NOTE A NO-Load test is performed in a similar manner, by pressing the <noXfer soft key> on the exerciser\test screen.


SECTION 4 Graphical Control Panel Page 27 of 125

SECTION 4 Graphical Control Panel There are four methods of interfacing with the RPTCS ATS Controller:

Interfacing via the graphical control panel. Interfacing via remote inputs.

Overview

The RPTCS graphical control panel provides the operator with rapid access to relevant information and controls using intuitive sequences. It also provides all available information and setting control, again with intuitive sequences.

Introduction

The central feature of the graphical control panel is an 89 mm (3.5-inch) 320 by 240 pixel backlit color LCD screen. The panel also contains keys (pushbuttons) that control the display and perform commands. In addition, the interface contains ALARM RESET, TEST, CONTROL, and INFO direct acting control pushbuttons. The display also contains several LED indicators that provide a summary of the machine status. Details are displayed on the screen when the user navigates to the appropriate page.

Graphical Display

Each display page consists of the three components shown below:

Header Soft Key Labels Selected Page



Header Bar

The header bar (white text on a blue background) displays the hierarchical path name, the date and time in 24-hour format, and the current password access level. The hierarchical path is always displayed on the left top side of the graphical display. The present time is displayed on the right top side.

Soft Key Labels

The soft-key labels are indicated on the bottom line. The soft-keys are used for navigation, performing functions, and for acknowledgement.

Navigation: soft-keys can be used to traverse across and down the hierarchy of pages. Functional: soft-keys can be used to perform page-specific functions. Acknowledgement: soft keys can be used to acknowledge popup windows.

Soft-keys labels change to show relevant selections for the displayed screen. The color of each soft-key label indicates its functionality. Soft-keys are highlighted for the displayed page, unauthorized keys are “greyed-out”, and unused keys are not displayed.

Selected Page

The remainder of the screen shows the selected page. Pages are organized in a hierarchical or tree-based menu structure. To improve readability, some pages are labeled with rectangular outlines or colored backgrounds. Some pages contain too many fields to display at once. These pages display arrows bars at the right edge to indicate that the page continues below the screen. When recalled, scrolled pages are re-positioned at the top of the page.

Fields display actual value or setting information, and have behaviors that allow help display, editing, and control. Each Actual Value analog field displayed on the home page has an associated alarm limit and changes color to orange when that limit is exceeded. Fields with an associated trip limit change their color to red when that limit has tripped. Fields that are disabled or unavailable are greyed-out.

Key Pad The function keys perform the labeled functionality. The summary of function key operation is shown below.

KEY OPERATION

HOME Single press recalls the home page; double press recalls the default display

UP Scroll up page, select field, tab to next field, increment value

DOWN Scroll down page, select field, tab to previous field, decrement value

ESC Single press closes pop-up, cancels editing, deselects field, moves to previous page; sustained press logs out (cancels security passcode entry)

ENTER Single press freezes scrolling and selects field, edits selected field, saves edited value;



double press sets the selected field/page as default; sustained press logs in (enter security passcode)

HELP Displays context sensitive help and Modbus address

Home

The HOME key always recalls the root or home page. The home page allows access to all sub-pages and also contains a status and process values summary. Double pressing the HOME key recalls the default display. Like a screen-saver, the default display appears after a period of inactivity and displays user-selected information.

UP and Down Key

The UP and DOWN keys function in different ways depending on their context.

Where a scroll bar is displayed, the UP and DOWN keys scroll the page up and down. Where there is no scroll bar or it is greyed-out, the first press of the UP and DOWN keys selects

the first field. Subsequent presses tab up and down through the fields, scrolling as required. When a field is open for editing, the UP and DOWN keys increment/decrement the value of that

field.

Enter Key

The ENTER key functions in different ways depending on its context.

If there are no selected fields, the ENTER key will freeze any scroll bars and select the first field on the display.

If a field is selected, pressing ENTER will attempt to open it for editing. If a field is opened for editing, pressing enter will exit the edit sequence. Double pressing the ENTER key at any time selects the displayed page as the default display. A sustained press on ENTER prompts the security passcode and displays a dialog box that

allows passcode entry.

ESC Key

The ESC key functions in different ways depending on its context.

If a pop-up dialog box is displayed, the ESC key closes it. If an edit sequence is in progress, the ESC key cancels the edit. If a field is selected, the ESC key de-selects it. In all other instances, the ESC key moves back one page in the menu structure. A sustained press on the ESC key clears the security passcode and prompts for confirmation.

HELP Key The HELP key functions in different ways depending on its context.

If a field is selected, the HELP key displays a help window for the field. If a help window is displayed, the HELP key closes it.

Help windows are also closed when any other key is pressed. A typical help window is shown below.



Pressing an invalid key displays a message explaining the problem and recommending a solution. Where the keypress is invalid because a security passcode is required, the dialog window will be a passcode entry window.

Control Keys

The RPTCS has four large direct control keys: ALARM RESET, TEST, CONTROL, and INFO.

ALARM RESET: allows the user to reset certain alarm conditions. TEST: takes the user directly to the System Test Screen. CONTROL: takes the user directly to the Control Screen that allows the user to select certain

modes of operation. INFO: takes the user directly to the Event Report screen.

LED indicators

The control panel LEDs summarize the status of the transfer switch:.

ALARM: indicates that there is a problem with the ATS, or that a user configurable alarm condition is active, or that the ATS is not in AUTO mode.

TD ACTIVE: indicates that the controller is timing before taking the next control action. XFER INHIBIT: indicates that the controller will not automatically transfer to the other source

and that operator intervention is required. S1 (Source-1, typically utility power) Available LED: indicates that S1 is present and within

user defined limits. S2 (Source-2, typically generator power) Available LED: indicates that S2 is present and within

user defined limits. S1 (Utility) Status LED: indicates that the load is connected to S1 power. S2 (Generator) Status LED: indicates that the load is connected to S2 power.

Home Page

The home page represents the root of the entire menu structure. An overview of the system status is displayed which indicates the following items:

ATS Status banner Type of ATS being controlled



Amperage rating of ATS Voltage rating of ATS Source 1 type Source 2 type Preferred source selection Information on the System Exerciser Information regarding the last load transfer.

The Values, Status, Setpoints, Diag, and Exerciser soft-keys are displayed on the home page. The Status soft-key will be highlighted if any alarm condition is present.

Pressing any of the soft-keys displays the first sub-page in the hierarchy. Pressing the ESC key within any of these sub-pages returns directly to the home page.

Default Display

The default display is automatically shown when no control key has been pressed for five minutes. It can also be recalled at any time by double-clicking the HOME key.

The default display can be set to the home page, any actual values page, or any status page. A page can be set to be the default display by navigating to that page and double-pressing the ENTER key. The default display setting is saved in non-volatile memory.

If a page is set as the default display, the soft-keys will be those of the selected page.

Actual Values Pages

The actual values pages are divided into five sections.

Summary (overview of primary actual values) Amps (metered current values) Volts (metered voltage values) Power (metered power values) PQ (metered power quality values)

The actual values summary page displays a summary of the analog actual values. The current, voltage, power, and PQ actual values pages are accessible from the summary page through the corresponding soft-keys at the bottom of the screen.

A typical actual values screen is shown below.



Status Pages The status pages provide the user with up-to-date information on the current status of the ATS that the RPTCS is controlling.

Status pages are divided into five sections.

Message (displays all locked out conditions plus conditions such as alarms, internal faults, control status, etc.).

Inputs (displays the present state of assigned contact inputs). Outputs (displays the present state of assigned contact outputs). System (displays the present state of the communications interface). Flex (displays the present state of the FlexLogic™ engine and number of lines used.)

A typical display is shown below:

Message types are classified by color and associated icon type, as follows:

Red Triangle = Alarm Orange Square = Status Black Text = Information Message

Message can have an associated countdown timer, if applicable.

When the controller is first powered up, the status page will display any parameters that must be entered for proper operation of the associated ATS.

Inhibits



These include Transfer Inhibits like "Inhibit transfer to S1".

Faults / Alarms

These trigger depending on the respective protection setpoints. A typical example would be “S1 Failure.”

Information Messages

Information can be one of two types:

information only

information with navigation (marked on the Status page with an Enter symbol on the right)

By pressing the Enter key when an information message with navigation is highlighted, the Grapical Control Panel will take the user directly to the respective page.

Setpoints Pages

The Setpoints pages are divided into five sections.

Config (contains basic configuration setpoints) Operation (contains range limits for both power sources and timer values for transfer operations) Control (contains basic control function setup, also accessible via the green CONTROL key) Security (contains the password security setpoints) Factory (for access by GE only)

The Home > Setpoints page displays a warning message concerning unexpected performance if setpoints are improperly changed. It is recommended that all relay outputs capable of causing damage or harm be blocked before a setpoints change is made and it is clear the relay is performing as intended with the new setpoints.

To streamline the setpoint entry process, the graphical control panel will not display setpoints that are not relevant at the specific instance. For instance, if a process interlock function is disabled, the six setpoints associated with that interlock function will not be displayed. If all ten process interlock functions are disabled, the RPTCS will display only 10 successive “Disabled” list items. If one of the interlock functions were then enabled, then room is made on the display for the six setpoints which are now functional.

The setpoint pages are in a common format of up to twelve lines. Each line has a column that displays the setpoint name and unit, and another column displaying the value entered.

The Home > Setpoints > Config > CT-VT page is shown below.



Diagnostics Pages

The diagnostic pages are divided into five sections.

Events (event recorder data for up to 256 events) Stats (statistical data on the last transfer event) Phasors (metered phasor data) About (product information)

Typical diagnostic pages for Events, Stats, Phasors, and Product Information are shown below.



Control Page

This page is used to view the active control modes. For example, selection of primary source, automatic vs. manual initialization of transfer, etc.

Popup Windows

There are three types of popup windows:

• Setpoint editor popup windows. • Help popup windows. • Invalid operation popup windows.

Refer to the Setpoints chapter for details on setpoint editor popup windows.

Help popup windows are initiated by pressing the HELP key. This will display help text for the active setpoint field.



Invalid operation popups explain the problem and provide direction on how to rectify it. This may also include invalid features or uninstalled options. Where a keypress is illegal because a security passcode is required, the popup is a passcode entry dialog box.

Help and illegal action popup windows remain open until they are acknowledged by clicking any soft or hard key, or until a pre-determined period of inactivity has passed.

Test

The Test page can be accessed by pressing the green Test button located on the front of the graphical display. It can also be accessed from the Home > Exerciser > Test page.

This page displays the RPTCS system test choices, as shown below. From the Test screen the user can perform the same operations as performed by the exerciser. Whereas exercises are performed automatically, a Test always has to be initiated by the user. The user must be logged in with the appropriate pass code to perform any of these tests.

There are four types of test: Xfer Load, No Xfer, Peak Shave and LED Test. The screen also provides an ‘End’ button to abort any of the two test types. Once any of these modes are active, a yellow banner highlights the selection.



Xfer Load

In order to simulate a load transfer as if an outage was occurring, the operator can select the Xfer Load test. With this test type, the engine will start up and the load will transfer according the Engine Start Time Delay followed by the Time Delay to Non-preferred Source. When the test is ended by depressing the END button, the switch will go through the Time Delay to Preferred Source before actually transferring back to the utility.

NOTE: Once a Xfer Load command has been issued and the alternative source has reached an acceptable level of voltage and frequency, the test cannot be aborted. If the user tries to end the test at this point, the load will still be transferred to the alternate source, but the return sequence will immediately activated.

No Xfer

For testing the functionality of the engine generator set only, the operator can initiate a NoXfer test. In this case will engine will start up, but the load will not be transferred.

Peak Shave

A peak shave test is very similar to a Xfer Load test except that during the retransfer to the preferred source the transfer to preferred source time delay is temporarily reset to five seconds. This allows the operator to quickly retransfer back to the preferred source when the peak shave test is ended.

LED Test

Pressing this button flashes all of the LEDs that are on the front of the graphical display.

Test Mode and Fail to Transfer

If the ATS cannot successfully retransfer back to preferred position due to mechanical or electrical control issues it will seek the non preferred source to reenergize the loads. The fail to transfer logic invokes the Test mode to keep the ATS in this position until the ATS can be properly inspected.

SECTION 9 Setpoints Page 48 of 125

SECTION 9 Setpoints CAUTION Great care has to be used when switching the standard mode of operation to “Dual Transition”. In this mode, the controller will not synchronize the two sources. Adequate time delay for the "Center-off position to Non-Preferred Source" and "Center-off position to Preferred Source" timers has to be selected to make sure any rotating loads have enough time to coast to a stop before selecting the Dual Transition mode. If this is not taken into account, severe damage to rotating equipment can occur!

Understanding Setpoints

Any of the ATS setpoints may be viewed or altered by pressing the Setpoints soft-key. Setpoints data is divided into four pages.

Configuration page: Information about the ATS configuration as well as system setup, inputs, outputs, communications, CTs, and VTs, events, and data log.

Operation page: Information about the two power sources, such as failure points for voltage and frequency, and failure time delays.

Control page: Operator access to different modes of operation. Security page: Information about the security and password features.

Press the Setpoint soft-key to scroll through the setpoints pages. When pressed for the first time, the following screen is displayed.

The soft-keys on the Home > Setpoints page open pages two levels down, since the pages immediately below this page are blank. For example, the Config soft-key opens the Home > Setpoints > Config > ATS page. The pages containing setpoint fields, except for the inputs and outputs pages, are in a common format. This is a simple tabular format with two columns: setpoint name and units, and setpoint value. Setpoints for features that are not enabled are omitted from the page.

CAUTION Setpoints may be changed while the ATS is in operation; however it is not recommended to change parameters while the ATS load is fed from Source 2.

Setpoints will remain stored indefinitely in the internal non-volatile memory even when control power to the RPTCS is removed. Protection parameters are based on the entered data. This data must be complete and accurate for the given system for reliable protection and operation of the ATS.



Setting Text Abbreviations

The following abbreviations are used in the setpoints pages:

A, Amps: amperes AUX: auxiliary COM, Comms: communications CT: current transformer GND: ground Hz: Hertz MAX: maximum MIN: minimum SEC, s: seconds UV & U/V: undervoltage VT: voltage transformer Ctrl: control Hr & hr: hour UTC: coordinated universal time ops: operations

Setpoint Editing

To streamline the setting entry process, the graphical control panel omits non-functional settings from the display.

CAUTION Settings may be changed while the automatic transfer switch is energized. However, appropriate measures must be taken to limit the consequences of entering unintended or misunderstood setting values. Consequences of inappropriate settings to the specific application at hand include loss of protection, loss of control, and undesired starting or stopping.

Enumeration Setpoints

Enumeration settings select from a limited set of values (for example, enabled or disabled). The following procedure describes how to edit an enumeration setting.

1. Use the soft-keys to select the relevant setting page. 2. Use the UP and DOWN keys to select the relevant setting field. 3. Press the ENTER key. A popup window will appear with a list of available values. 4. Use the UP and DOWN keys to select from the available values. If there are more than seven

available values, then an arrow indicator will appear on the lower right of the popup to indicate additional selections.

5. Press the ENTER key when complete to exit the edit sequence. The selection will be automatically saved.

6. Press Esc to cancel the edit and leave the setpoint unchanged.



Numeric Setpoints Numeric setpoints accept a numerical value within a specific range. The numeric setpoint editor is a numeric input panel, with the current value shown on the number display. The minimum, maximum, step, and default values are shown on the left of the keypad, and the label of the setpoint being edited is displayed on the menu bar of the setpoint editor.

The navigational soft keys change the numeric key in focus, which is highlighted in orange. There are also five functional soft-buttons in the popup window.

BkSpc: This key performs the backspace function, clearing the last digit or decimal from the display.

CLR: This key clears the field’s value from the display Default: This key returns the setpoint value to its default value. OFF: This key disables the setpoint and is visible only for setpoints that can be disabled.

In order to activate the functions offered by these buttons, the user has to highlight the appropriate button and press "Select".

The UP and DOWN front panel keys can also be used to increment and decrement the setpoint by its step value. Clicking the ENTER key verifies the displayed value. If the setpoint value is valid, it is stored as the new setpoint value and the editor is closed. Otherwise, an error statement is displayed and the Default soft-button is brought to focus. Clicking HOME before the value is stored cancels the edit sequence and recalls the home page.

The following procedure describes how to edit a numeric setting.

1. Use the navigation keys to select the relevant setting page. 2. Use the navigation keys to select the relevant setting field.



3. Press the ENTER key to open the numeric setpoint editor. 4. Use the navigational soft-keys to highlight the first digit of the new setpoint value. 5. Press the SELECT soft-key to select the highlighted digit. 6. Use the navigational soft-keys to highlight the next digit, then press SELECT. 7. When the new value has been fully entered, press the ENTER key to store the value and close

the window.

Alphanumeric Setpoints

Alphanumeric setpoints accept any alphanumeric value of a specified size and are generally used for labeling and identification purposes. When an alphanumeric setpoint is selected, the RPTCS displays an alphanumeric setpoint editor window.

A flashing underline marks the current character. The “<” and “>” soft-keys shift the cursor left and right. When the cursor is at the extreme right hand side of the field and the field has not reached its maximum length of string input, the “>” key shifts the cursor to the right and sets the selected character to the space character. Up to 20 characters can be stored for alphanumeric setpoints. A long click of the “<” and “>” soft keys move the cursor to the first or last character in the string.

The up and down soft-keys increment and decrement the selected character through the character set. A long click of the up or down soft-keys sets the selected character to “a” and “Z”, respectively. The shift soft-key toggles the case of the character set. Pressing ENTER stores the selected value, while pressing ESC cancels the editing sequence and closes the popup editor.

The following procedure describes how to edit an alphanumeric setting.

1. Use the soft-keys to select the relevant setting page. 2. Use the ARROW soft-keys to select the relevant alphanumeric setpoint field. 3. Press the ENTER key to open the alphanumeric setpoint editor. 4. The first character of the alphanumeric setting value will be marked with a flashing cursor

(underline). 5. Use the UP, DOWN, LEFT, RIGHT, SHIFT, and SPACE soft-keys to change the indicated

character. 6. Use the LEFT and RIGHT ARROW soft-keys to select and change more characters. 7. Press the ENTER key when complete to exit the edit sequence. The changes are automatically

saved.

Date, Time, and IP Entry

The entry process for date, time, and IP setpoints follows the same convention as numeric setpoints, where the day, month, year, hour, minute, second, and each octet of the IP address are entered as separate fields. Input verification is performed for all fields of the setpoint when the ENTER key is pressed. As these are standard formats, the minimum, maximum and step value displays are removed. For date and time setpoints, a format string of DD/MM/YYYY or HH:MM:SS is included as a part of the setpoint label for reference when entering a new value.



Security Access

There are three levels of security access allowing write access to setpoints, lockout reset, and firmware download. When there are no pop-ups present, a sustained press on the ESC key clears the security passcode. When operations are performed that require a higher level of security, a passcode entry dialog box automatically opens (for example, in entering factory page at read only security access).

The encrypted key information appears only when the current security access level is 0.

Factory Configuration Setpoints

The configuration setpoints contain data on ATS configuration as well as system setup, inputs, outputs, communications, CTs, and VTs. The following sub-pages are available.

ATS (setpoints related to ATS configuration). CT-VT (setpoints related to CT and VT configuration). Inputs (setpoints related to digital input configuration). Outputs (setpoints related to digital output configuration). Comms (setpoints related to communications configuration). System (setpoints related to RPTCS system configuration). Events (setpoints related to the event recorder). Counters (setpoints related to the digital counters).

ATS

The RPTCS can control the following types of transfer switch:

1. Standard (Open) Transition (with or without bypass isolation) 2. Dual Transition (with or without bypass isolation) 3. Closed Transition (with or without bypass isolation)

The home screen tells the user for which application a particular RPTCS is suitable. The figure below shows the home screen for a Closed Transition type controller.

NOTE It is important not to confuse the type of ATS being controlled, with the mode in which it is being operated. For example, a Closed Transition type switch can be operated in Closed Transition Mode or in Delayed Transition Mode.

Select the Home > Setpoints > Config > ATS page to edit the ATS data settings.

Basic Sequence of Operation

Open Transition –Single Operator

Loss of Power

1. Upon loss of “S1” Power, if the “Commit Transfer to S2” feature of the Controller is disabled:

When the Source 1 voltage or frequency has fallen below the values as set up in the Setpoints > Operations > S1 Settings Screen, the Controller initiates the Time Delay to Generator Start and the S1 Sag Timer. Upon the completion of the Time Delay to Generator Start, an Engine Start Signal is sent to Source 2, typically an engine generator set. When frequency and Voltage of S2 reach the values as set up in the Setpoints > Operations > S2 Settings Screen, the Time Delay to S2 begins timing. The Time Delay to S2 ensures that Source 2 is stable before actually transferring to this Source. If (and only if) the “S1” source is still interrupted or out of limits at the end of this timer cycle, the RPTCS energizes the Operator to move the Switch to the S2 Position, transferring the load to Source 2. If “S1” returns with all parameters within limits during this time delay, then transfer to “S2” is aborted. In this case, at the end of the “Time Delay Transfer to S2” cycle, the adjustable “Time Delay for Engine Cooldown” starts; at the end of the Cooldown Timer Cycle, the Controller sends a signal to the “S2” generator to shut down, and the system becomes ready for the next “S1” Source outage.

Non Commit Logic

Given that both sources are available the ATS always prefers to transfer to the Preferred Source (typically a Utility Source). During a Preferred Source failure, Non Commit logic always tries to transfer the ATS to the first available source and prevent any additional transfer sequences.



Once the Non Preferred Source is available the Time Delay to Non Preferred Source timer is timing and the transfer sequence is initiated. If the Preferred Source becomes available during this timing sequence, the transfer to the Non Preferred Source will be halted and the ATS will stay in the Preferred Source position.

If the Inhibit Transfer to S2/Block Transfer Relay accessory is being used the transfer sequence is halted. It is now waiting for the BTR signal from the remote switchgear. If the Preferred Source becomes available during this period the transfer to the Non Preferred Source will be halted and the ATS will stay on the Preferred Source

OR

Upon loss of “S1” power, if the “Commit Transfer to S2” feature of the controller is enabled:

When the Source 1 Voltage is interrupted or the Source 1 Voltage or frequency has fallen below the values as set up in the Setpoints > Operations > S1 Settings Screen, the Controller initiates the Time Delay to Generator Start and the S1 Source Sag Timer. Upon the completion of the Time Delay to Generator Start, an Engine Start Signal is sent to Source 2, typically an engine generator set. When frequency and Voltage of S2 reach the values as set up in the Setpoints > Operations > S2 Settings Screen, the Time Delay to S2 begins timing. The Time Delay to S2 ensures that source 2 is stable before actually transferring to this Source. If desired, the Operator can bypass this Timer from the Status Screen, or through a remote signal. After the Time Delay to S2, the RPTCS energizes the Operator to move the Switch to the S2 Position, transferring the load to Source 2.

Commit Logic

Given that both sources are available the ATS always prefers to transfer to the Preferred Source, but also will still seek the first available source.

During a Preferred Source failure, Commit logic commits to transfer once the Non Preferred Source is available.

Once the Non Preferred Source is available the Time Delay to Non Preferred Source is timing and the transfer sequence is initiated. The logic is now committed to transfer to the Non Preferred Source. If the Preferred Source now becomes available it will ignore it and continue on with its transfer which will cause an additional transfer outage to the load.

If the BTR accessory is being used, the transfer sequence is halted waiting for the BTR signal from the remote switchgear. If the Preferred Source now becomes available the transfer will be halted and the ATS will stay on the Preferred Source position.

2. The “Time Delay Transfer to S2” can be bypassed by Operator action via the RPTCS, once the generator power source is available and within limits, to force a transfer earlier.

3. When the ATS is in the “S2” position, the “Home Screen” on the RPTCS will indicate “Load Connected to S2”.

Restoration of Power

4. With the ATS load connected to the “S2” Source, when the “S1” Source recovers with all parameters within limits, as set up in the Setpoints > Operations > S1 Settings Screen, the Controller initiates a retransfer to Source 1. In order to ensure that the Utility Voltage and frequency are stable before retransferring back to Source 1, the Time Delay to the Preferred Source Timer begins to time for a period of time as set up by the User, typically set to 30 minutes. If the User wishes to retransfer before this Timer has expired then highlight the Timing Message on the Status Screen and bypass the Timer by pressing the Bypass Soft Key. When the Time Delay to Preferred Source has timed out or the Bypass Key has been pressed, the ATS will transfer the load back to Source 1.

5. Time Delay for S2 Sag: With the ATS load connected to the “S2” Source, and with the Time Delay to the Preferred Source Timer timing, if the “S2” Generator momentarily sags or swells



beyond the limits, the Controller attempts an immediate retransfer back to the good “S1” Source. The inherent delay of sensing this sag is less than 250 msec. The User can choose to add delay to this process by increasing the Time Delay for Generator Sag Timer in one-second increments.

6. The “Time Delay Transfer to S1” can be bypassed by operator action via the RPTCS, once the Utility Power Source is available and within limits, to force a bypass earlier.

7. Once the Retransfer to “S1” has occurred, the Controller starts the adjustable “Time Delay for Engine Cooldown” Timer, which keeps the engine/generator running, unloaded, to allow the engine to cool before shutting down. When this timer expires, the controller sends a signal to the “S2” generator to shut down, and the system becomes ready for the next “S1” Source outage. This Timer can be bypassed by Operator action via the RPTCS to force an earlier shutdown of the engine.

Fail to Transfer

1. The RPTCS controls the ATS by sending signals to the single S1 Operator. This operator moves the Mechanical Overcenter Main Contact Assembly for the given Source. During normal operation the Controller sends only one signal in order to transfer to the desired source. The Controller also has the ability to sense and react to the Fail to Transfer events. Fail to Transfer events could be caused by a failure of the Electric Operator or the Mechanical Overcenter Device.

2. The Controller sends only three transfer signals. If the ATS does not change position as expected the Controller annunciates “Any Transfer Failure” in the Event Log and lights the Alarm Led on the RPTCS. If the ATS loads are thus de-energized and the previous source is still good and available, the ATS attempts to retransfer back to it. The alarm output “Any Transfer Failure” can also be programmed for an external annunciation.

3. Upon a Failure to Transfer situation, the Automatic Transfer Sequence is temporarily halted. The Sequence reinitiates if a new Transfer Request is started. The new Sequence could be started by either a change of Source availability or resetting the Load-Test function.

4. Test Mode and Fail to Transfer. If the ATS cannot successfully retransfer back to preferred position due to mechanical or electrical control issues it will seek the non preferred source to reenergize the loads. The fail to transfer logic invokes the Test mode to keep the ATS in this position until the ATS can be properly inspected.

Open Transition –Dual Operator

Loss of Power

1. Upon loss of “S1” power, if the “Commit Transfer to S2” feature of the controller is disabled:

When the Source 1 is interrupted or the Source 1 Voltage or frequency has fallen below the values as set up in the Setpoints > Operations > S1 Settings screen, the Controller initiates the Time Delay to Generator Start and the S1 Sag Timer. Upon the completion of the Time Delay to Generator Start, an Engine Start Signal is sent to Source 2, typically an engine generator set. When frequency and Voltage of S2 reach the values as set up in the Setpoints > Operations > S2 Settings Screen, the Time Delay to S2 begins timing. The Time Delay to S2 ensures that source 2 is stable before actually transferring to this Source. If desired, the Operator can bypass this Timer from the Status Screen or through a remote signal. If (and only if) the “S1” Source is still interrupted or out of limits after the Time Delay to S2 expires, the RPTCS energizes an Operator to move the Switch to the OPEN Position, where the load is not connected to either source. Once the Switch is in the OPEN Position, the Time Delay Center-Off to S2 Timer starts its timing cycle. Upon completion of the Time Delay Center-Off to S2, the RPTCS energizes an Operator to transfer the load from the Cerner-off Position to Source 2. The load is then powered from “S2”. If “S1” returns with all parameters within limits before “Time Delay Transfer to S2” completes, then Transfer to “S2” is aborted. If the Transfer is aborted, at the end of the “Time Delay Transfer to S2” Cycle, the adjustable “Time Delay for Engine Cooldown” starts; at the end of the Cooldown Timer Cycle, the controller



sends a Signal to the “S2” generator to shut down, and the system becomes ready for the next “S1” Source outage.

Non Commit Logic

Given that both sources are available the ATS always prefers to transfer to the Preferred Source (typically a Utility Source). During a Preferred Source failure, Non Commit logic always tries to transfer the ATS to the first available source and prevent any additional transfer sequences.

Once the Non Preferred Source is available the Time Delay to Preferred Source timer is timing and the transfer sequence is initiated. If the Preferred Source becomes available during this timing sequence, the transfer to the Non Preferred Source will be halted and the ATS will stay in the Preferred Source position.

If the ATS successfully transfers to the Center Off position and the Inhibit Transfer to S2/Block Transfer Relay accessory is being used the transfer sequence is halted. It is now waiting for the BTR signal from the remote switchgear. If the Preferred Source becomes available during this period the transfer to the Non Preferred Source will be halted and the Time Delay Center Off to Preferred Source timer will begin timing to reclose back the Preferred Source

If the BTR input is satisfied before Preferred Source becomes available the Time Delay Center Off to Non Preferred Source timer will begin timing to close to the Non Preferred Source. Once this begins timing the sequence is finally committed to transfer. If the Preferred Source now becomes available during this period it will be ignored until the ATS is on the Non Preferred Source.

OR

Upon loss of “S1” power, if the “Commit Transfer to S2” feature of the controller is enabled:

When the Source 1 is interrupted or the Source 1 voltage or frequency has fallen below the values as set up in the Setpoints > Operations > S1 Settings screen, the Controller initiates the Time Delay to Generator Start and the S1 Sag Timer. Upon the completion of the Time Delay to Generator Start, an Engine Start Signal is sent to Source 2, typically an engine generator set. When frequency and Voltage of S2 reach the values as set up in the Setpoints > Operations > S2 Settings Screen, the Time Delay to S2 begins timing. The Time Delay to S2 ensures that Source 2 is stable before actually transferring to this Source. If desired, the Operator can bypass this timer from the Status Screen or through a remote signal. After the Time Delay to S2, the RPTCS energizes an Operator to move the Switch to the OPEN Position, where the load is not connected to either source. Once the switch is in the OPEN position, the Time Delay Center-Off to S2 Timer starts its timing Cycle. Upon completion of the Time Delay Center-Off to S2, the RPTCS energizes an Operator to transfer the load to Source 2.

Commit Logic

Given that both sources are available the ATS always prefers to transfer to the Preferred Source, but also will still seek the first available source.

During a Preferred Source failure, Commit logic commits to transfer once the Non Preferred Source is available.

Once the Non Preferred Source is available the Time Delay to Non Preferred Source is timing and the transfer sequence is initiated. The logic is now committed to transfer to the Non Preferred Source. If the Preferred Source now becomes available it will ignore it and continue on with its transfer which will cause an additional transfer outage to the load.

If the ATS successfully transfers to the Center Off position with the Preferred Source available and the BTR accessory is not being used the transfer sequence is still committed and continues on to the Non Preferred Source.



If the ATS successfully transfers to the Center Off position and the BTR accessory is being used, the transfer sequence is halted waiting for the BTR signal from the remote switchgear. If the Preferred Source now becomes available the transfer will be halted and the ATS will retransfer back to the Preferred Source position.

If the ATS successfully transfers to the Center Off position and the Non Preferred Source becomes no longer available the transfer sequence is halted waiting for either source to become available. The ATS will transfer to which ever source energizes first.

CAUTION Severe damage to equipment may occur.

Make sure that the value entered for “Time Delay Center-Off to S2” is sufficient to allow rotating loads to coast to a stop. Damage to connected rotating equipment can occur if too small of a time value is selected.

2. The “Time Delay Transfer to S2” and “Time Delay Center-Off to S2” Timers can be bypassed by Operator action via the RPTCS, once the generator power source is available and within limits, to force a transfer earlier.

3. In the Dual Open Transition Configuration, the ATS keeps the load connected to the preferred Source “S1” until the “S1” Switch Contacts move to CENTER-OFF; if “S1” returns before that operation, then the load is immediately repowered by “S1” regardless of the Voltage and/or frequency condition of that source.

4. When the ATS is in the “S2” Position, the “Home Screen” on the RPTCS will indicate “Load Connected to S2”.


5. With the ATS load connected to the “S2” Source, when the “S1” Source recovers with all parameters within limits, as set up in the Setpoints > Operations > S1 Settings Screen, the Controller initiates a Retransfer to Source 1. In order to ensure that the utility Voltage and frequency are stable before transferring back to Source 1, the Time Delay to Source 1 Timer begins to time for a period of time as set up by theUser, typically set to 30 minutes. If the User wishes to retransfer before the Time Delay to S1 Timer has expired, then highlight the timing message on the Status Screen and bypass the Timer by pressing the Bypass Soft Key. When the Time Delay to S1 Timer has timed out or the Bypass Key has been pressed, the RPTCS Controller will energize an Operator and the ATS will move to the OPEN/NEUTRAL Position. Once the Switch is in the OPEN Position, the Time Delay Center-Off to S1 Timer starts its Timing Cycle. Upon completion of the Time Delay Center-Off to S1 Timer, the RPTCS energizes an Operator to retransfer the load back to Source 1.

6. Time Delay for S2 Sag: With the ATS load connected to the “S2” Source, and with the Time Delay to the Preferred Source Timer timing, if the “S2” Generator momentarily sags or swells beyond the limits, the Controller attempts an immediate retransfer back to the good “S1” Source. The inherent delay of sensing this sag is less than 250 msec.

7. The User can choose to add delay to this process by increasing the Time Delay for Generator Sag Timer in one-second increments.


Make sure that the values entered for 'Delay - Neutral to S1' and/or 'Delay - Neutral to S2’ are sufficient to allow rotating loads to coast to a stop. Severe damage to connected rotating equipment can occur if too small of a time value is selected.

8. The “Time Delay Transfer to S1” and “Time Delay Center-Off to S1” Timers can be bypassed by Operator action via the RPTCS, once the Utility Power Source is available and within limits, to force a transfer earlier.

9. The controller maintains the engine start/run signal for the time period specified as the Time Delay to Engine Cooldown in order to ensure proper cooling of the engine before shutting it down. If the Operator desires to turn off the engine before the Time Delay to Engine Cooldown



has expired, then highlight the Timing Message on the Status Screen and bypass the Timer by pressing the Bypass Soft Key. When the Time Delay to Engine Cooldown has timed out or the Bypass key has been pressed, the Engine Start Signal is removed, causing the engine to shut down, and the system becomes ready for the next “S1” Source outage.

Fail to Transfer

10. The RPTCS controls the ATS by sending Open and Close Signals to the S1 and S2 Operators. These Operators move the Mechanical Over-center Main Contact Assembly for the given Source. During normal operation the Controller sends only one signal to each Operator (Open or Close) in order to transfer to the desired source. The Controller also has the ability to sense and react to the Fail to Transfer events. Fail to Transfer events could be caused by a failure of the Electric Operator or the Mechanical Over-center Device.

11. During Open Transition Transfers the Controller always sends Open Signals before issuing the Close Command to the next Source. The Controller sends only three Open or Close Signals. If the ATS does not change position as expected the Controller annunciates “Any Transfer Failure” in the Event Log and lights the Alarm Led on the RPTCS. If the ATS loads are thus de-energized and the previous source is still good and available, the ATS attempts to retransfer back to it. The alarm output “Any Transfer Failure” can also be programmed for an external annunciation.

12. Upon a Failure to Transfer situation, the Automatic Transfer Sequence is temporarily halted. The Sequence reinitiates if a new Transfer Request is started. The new Sequence could be started by either a change of Source availability or resetting the Load-Test function.


Closed Transition- Dual Operator

Closed transition transfer switches are designed to transfer a load between two available Synchronized Sources without interrupting power to the load, (i.e. in a Make-Before-Break configuration). The actual paralleling of the two sources typically occurs within a time period of 100 ms. Closed Transition Operation can only occur when both sources of power (“S1” and “S2”) are available and within limits; thus transfer switches configured for Closed Transition can only operate in that manner when transferring back from “S2” to “S1” after a power outage, and when transferring between “S1” and “S2” in both directions during Exerciser Tests, and during Manual Transfer Operations. The switch reverts to Dual/Open Transition Operation, as described above, during the transfer from “S1” to “S2” after a Utility power outage, since the “S1” power will not be available.

In order for the controller to consider both sources synchronized, the following criteria have to be met:

Phase Rotation: match Voltage difference: less than Setpoint Limit Phase Angle difference: less than Setpoint Limit Frequency difference: less than Setpoint Limit

It is recommended that the customer keep the Phase Angle and Frequency difference at conservative settings to prevent nuisance tripping of feeder breakers due to out of synch window, current transients.

Loss of Power

Upon loss of “S1” Power, the transfer switch will operate as described in Open Transition –Dual Operator described above.


1. With the ATS load connected to the “S2” Source, when the “S1” Source recovers with all parameters within limits, as set up in the Setpoints > Operations S1 > Settings Screen, the



Controller initiates a retransfer to Source 1. In order to ensure that the Utility Voltage and frequency are stable before transferring back to Source 1, the Time Delay to Source 1 Timer begins to time for a period of time as set up by the User, typically set to 30 minutes. If the User wishes to re-transfer before the Time Delay to S1 has expired, then highlight the Timing Message on the Status Screen and bypass the Timer by depressing the Bypass Soft Key. When the Time Delay to S1 has timed out or the Bypass Key has been pressed, the RPTCS Controller will wait until both Sources are within the allowable Synchronization Limits and then will energize an Operator to connect the load with Source 1 while it is still connected to Source 2. Once both sources are connected to the load, the RPTCS Controller will immediately energize another Operator and the load will be disconnected from Source 2. The actual time during which both Sources are paralleled is typically less than 100 ms.

2. Time Delay for S2 Sag: With the ATS load connected to the “S2” Source, and with the Time Delay to the Preferred Source Timer timing, if the “S2” Generator momentarily sags or swells beyond the limits, the Controller attempts an immediate retransfer back to the good “S1” Source. The inherent delay of sensing this sag is less than 250 msec. The User can choose to add delay to this process by increasing the S2 Sag Timer in 100 millisecond increments.

3. The Controller maintains the Engine Start Signal for the time period specified as the Time Delay to Engine Cooldown Timer in order to ensure proper cooling of the engine before shutting it down. If the Operator desires to turn off the engine before the Time Delay to Engine Cooldown has expired, then highlight the Timing Message on the Status Screen and bypass the Timer by pressing the Bypass Soft Key. When the Time Delay to Engine Cooldown has timed out or the Bypass Key has been pressed, the engine start signal will be removed, causing the engine to shut down.

4. If both Sources do not synchronize within the programmed allowable time period, then the RPTCS Controller’s Alarm Light will come on, the Controller Display Screen will display the Banner Message "Sync Fail - Bypass Wait", and the Status Screen will display the Message "Sources out of Phase". If that occurs, the ATS will continue to be connected to the same Source presently powering the load, as long as that source is available. If the two sources become synchronized, then the Controller will transfer in Closed Transition Mode, as described above. In the event of synchronization failure, Operator action can be taken, via the RPTCS, to manually transfer the load to the other Source. In that case, the Switch will transfer in “Dual/Open Transition Mode”, as described above. This means that the load will be unpowered for the time period programmed for “Time Delay - Neutral to S1” or 'Time Delay - Neutral to S2”, respectively.


Make sure that the values entered for “Time Delay Center-Off to S1” and/or “Time Delay Center-Off to S2” are sufficient to allow rotating loads to coast to a stop. Severe damage to connected rotating equipment can occur if too small of a time value is selected.

5. During a Closed Transition Operation, with both Sources connected in parallel, if the ATS fails to open the Contacts for the Source away from which it is transferring, and both Sources remain paralleled for more than 100ms, the Controller will trigger an Alarm, and will attempt to reopen the contacts for the Source that had just been connected to the load in parallel with the first source (referred to as the “Open-Last-Closed” Feature).

6. If the Sources remain paralleled for 300ms, the Controller will trigger another Alarm Message. The Controller can also be programmed to operate a Programmable Output which, in turn, can be used to shunt trip, and thus disconnect, an upstream Circuit Breaker from either Source. This will ensure that the two Sources will not remain paralleled for an extended period of time.

7. External Hardware Relay Logic is provided to close a set of contacts in the event the Sources remain paralleled for more than 300 ms. These Contacts should be wired out to shunt trip at least one circuit breaker from either Source, upstream of the transfer switch.



8. All Closed Transition type Switches can also be programmed with an Audible Alarm Horn. This Output is activated under the three conditions listed below. In order to silence the Horn, the Operator must navigate to the Status Screen, highlight the “Audible Alarm” Message, and then press the Horn Silence Soft Key. Please note that the Horn Silence command will only execute when the Operator is logged in with at least Level 1 Security. In order to log in with Security Level 1, press and hold down the ENTER Button for three seconds and then enter the appropriate Password (Factory default 11111):

The two Sources don't become synchronized within 60 seconds while attempting to transfer to the other Source.

The ATS fails to disconnect from the Source from which it is transferring away and both Sources remain paralleled for more than 100ms (Open Last Closed Feature is being activated).

The Open Last Closed Feature fails and the Controller issues a Shunt Trip Command to an Upstream Source Circuit Breaker. Figure Closed Transition Power Outage Sequence of Events

Fail to Transfer

1. The RPTCS controls the ATS by sending Open and Close Signals to the S1 and S2 Operators. These Operators move the Mechanical Overcenter Main Contact Assembly for the given Source. During normal operation the Controller sends only one signal to each Operator (Open or Close) in order to transfer to the desired source. The Controller also has the ability to sense and react to Fail to Transfer events. Fail to Transfer events could be caused by a failure of the Electric Operator or the Mechanical Overcenter Device.

2. During Closed Transition Transfers the Controller always sends synchronized In-Phase Close Signals before issuing the Open Command to the next Source. The Controller only sends three In-Phase Close Signals. If ATS does not change position as expected it then annunciates “Any Transfer Failure” in the Event Log and illuminates the Alarm Led on the RPTCS. The alarm output “Any Transfer Fault” can also be programmed for an external annunciation.

3. The Automatic Transfer Sequence is now temporarily halted. The Sequence will reinitiate if a new Transfer Request is started. The new sequence could be started by either a change of Source availability or resetting the load test function.

NOTE: Once the two ATS sources are in parallel, the controller sends an open signal to the other set of contacts. This transfer occurs in fewer than 100 milliseconds. In the event this first signal does not open up the contacts a second open signal is sent to the original contacts. This action returns the ATS to the original source and occurs in fewer than 300 milliseconds.

4. In the event that neither of these Open Signals successfully isolates at least one Set of contacts, the FTT Timer Circuit operates. The FTT Contacts are dedicated to provide a remote shunt trip signal. The shunt trip signal should be wired to either source one or source two feeder breakers. The factory recommended default timer setting for this feature is 500 milliseconds. This circuit is completely outside and isolated from the RPTCS controller.

NOTE: The RPTCS also has an optional internal shunt trip function that can be programmed and then wired to duplicate the above feature.

5. If the ATS has experienced a Fail to Transfer event that left both sources paralleled and has subsequently operated the shunt trip contacts, the RPTCS becomes locked out from any further automatic transfers. On the Status screen, the status “ATS Lockout” is shown.

6. The FTT Trip Contacts can be wired to either the Source 1 or Source 2 feeder breaker. This Contact is now keeping a Trip Signal on that feeder breaker. No attempt should be made to close that feeder breaker until at least one Set of ATS Main Contacts is opened.

7. On the Banner at the top of the RPTCS Screen’s Status Message Page, the message “Waiting for Reset Key” is displayed, alerting the Operator that the Fail-to-Trip condition must be reset before the RPTCS is able to perform another operation. Resetting the Controller (as described



below) causes the ATS to transfer back to an energized Source and to no longer keep the Sources in parallel with each other.

8. In order to reset the RPTCS from the Lockout Condition, the Operator must first select the Status Window (if not already on that Window) by pressing the Status Soft Key. Once in that Window, use the Scroll-Down Function Key on the Status Page to highlight the Lockout Reset message and then press the Enter Function Key. This brings up a Dialog Box allowing the Operator to either Cancel or Reset the lockout with the appropriate Soft Key.


Fail to Synchronize/Sources out of Phase

1. When the RPTCS initiates a transfer sequence the Fail to Synch timer begins. It then has to wait for the two sources to be in phase. At the end of this timing period if the ATS has not successfully transferred the Sources out of Phase status and event will log.

2. This is an alarm feature only and does not stop the transferring sequence. Should the two sources come in phase after this alarm the ATS will transfer. If the operator wishes to stop the transfer sequence they can either set or reset the Load Test mode depending on which direction they were attempting to transfer to.

3. If the two sources do not come into phase but the operator still wishes to transfer they have two options. A bypass message will pop up on the Status page. Pressing this Bypass key will initiate an immediate Open Transition Transfer. The other option is to reset the transfer mode key switch back into open transition mode.

Block Transfer and Load Shed Operation

The RPTCS has the capability to protect emergency generators from overloading. This is done through the use of industry standard Block Transfer and Load Shed features.

1. Block Transfer (BTR, Inhibit Xfer to S2) When selected this input function, when not energized, will block the transfer of load to the S2 source. Typically this 24VDC signal is sent by remote emergency switchgear to a designated input. It usually is used to indicate that the generator bus is ready to load.

2. Bypass Block Transfer (internal on GCP) When momentarily selected this function on the GCP Status page allows the transfer to S2 even if the above input is not energized.

3. Bypass Block Transfer (external switch) An input and key switch can be added so when momentarily selected it will allow the transfer to S2 even if the above input is not energized.

4. Load Shed (LSR) When selected this function when energized will shed the load off S2 source. Typically this 24VDC signal is sent by remote emergency switchgear to a designated input. It usually is used to indicate that the generator bus is overloaded. If the S1 source is energized the ATS will attempt to retransfer back to it. If both the Load Shed and Block transfer signal are issued the Load Shed function will override the BTR signal. If the ATS is in Manual Mode, Load Shed will not function.

5. Local Load Shed The RPTCS has the ability to Load Shed without signals from a downstream remote Emergency Switchgear system. Source 2 (normally the generator source) can be protected with this Load Shed feature. It does this by monitoring the S2 source and insures that it stays within the desired setpoints. If the source exceeds these values the ATS will attempt to shed load from the S2 source. See page 90 for a full description. This can be activated by changing the parameters. These configuration options can only be accessed by the factory.



Common ATS Setpoints

Several setpoints are dependent on the chosen ATS type. The setpoints shown below are common for all ATS types. They are accessible as Modbus registers as well as through the Setpnt/Config/ATS screen.

ATS NAME Range: ATS, Up to 20 alphanumeric characters Default: ATS

This setpoint specifies a name for the ATS. This name will appear with the actual values, sequence of events record, and other reports

LOAD CONTROL TYPE (for up to 6 loads - LC1 through LC6) Range: Not Set/Elevator 1 or 2 or 3 Default: Not Set

Load control signals are used to protect certain loads during a transfer of the switch from one active source to the other. The following picture shows the screen that is used to activate load control outputs

Load control outputs selected as type Elevator 1 or 2 or 3 will close a contact prior to the load transfer. The operator can specify the time period during which the signal is activated by entering the desired value as ‘Pre Load Control x (LCx) Timer’. Unlike the ‘Pre Load Control x (LCx) Timer,’ the Elevator 1 or 2 or 3 signals will stay active after the load transfer has occurred for the time specified as ‘Post Load Control x (LCx) Timer’. Timer presets are selected for each load on the Setpoints\Operation\Timers screen and can range from 0 sec to 60 minutes.

When one or more Load Control outputs have been activated, the following will happen during a transfer sequence with both sources available (e.g. load test):

Immediately after the Time Delay to Non-Preferred Source or Time Delay to Preferred Source expires, the Load Control output is energized.

If several Load Control outputs have been selected by the user, the Load Control with the longest ‘Pre Load Control x (LCx) Time’ is activated, followed by the one with the second longest Pre Load Control Time, etc.

All load control pre-timers expire at the same time. When that happens, the RPTCS controller transfers the ATS from S1 to S2 or S2 to S1.

Preload Controlx (LCx) Timers de-energize immediately after the transfer. Load Control outputs for each Load Control output selected as ‘Load Disconnect’ remain

energized for the time specified as ‘Post Load Control Time’ for the respective load. The total time that a given Load control output is active, thus, is the sum of the ‘Pre Load

Control x (LCx) Timer’ and ‘the Post Load Control x (LCx) Timer’.



The Elevator 1 or 2 or 3 outputs will be energized, regardless whether one or two sources are available, i.e. they will be activated even during a transfer of the load due to a source failure.

Current and Voltage Transformers (CT-VT)

The figure below shows the CT-VT screen that allows the user to specify the kind of CT used in conjunction with the A card in slot E of the RPTCS controller (if applicable) and the type of connection for the voltage sensing for both sources.

Phase CT Type

Default: None - This is the secondary side of the external CT. It is strongly recommended to use 5A

secondary only. - Dependency: If CT card installed

VT Ratio

Default: 1.00 - Voltage transformer ratio. Required for medium voltage switches. Used where

primary voltage is greater than 600 VAC. - Dependency: None



ATS Secondary Voltage

Default: 480.00 - Transformer secondary voltage - Dependency: None

CT Primary

Range: 100 to 4000 A in steps of 1 Default: 100 A

- This is the primary nominal current injected into the external CT. - Dependency: If CT card is installed

3 Phase Voltage Connection

Default: Wye - Source 1, 3-phase connection style - Dependency: If ATS is in 3-phase mode

3 Phase Voltage Connection S2

Default: Wye - Source 2, 3-phase connection style - Dependency: If ATS is in 3-phase mode

Default: Generator



Load Phase Rotation Check

Default: Enabled

Load Phase Rotation

Range: ABC or CAB Default: ABC

- User has the three choices for rotation. Turn all sensing off, allow only ABC rotation or only CAB rotation.

Voltage IMB Fail LVL

Range: Off, 5 to 20% in steps of 1 Default: Off

- May be used to trigger an alarm if condition is true. - Dependency: ATS must be in 3-phase mode

Voltage IMB Restore

Range: 3 to 18% in steps of 1 Default: 8%

- Dependency: Voltage Iimbalance Fail Level should be on

Voltage IMB Fail DLV

Range: 1 to 60 s in steps of 1 Default: 30 s

- Dependency: Voltage Iimbalance Fail Level should be on Note: Although it is possible to enter different connection types for both sources, both wiring schemes

and selected connection type have to match. Unexpected results and possible damage to the switch can result if this is not observed.

Note: Only 5 A secondary connections are supported.

Inputs

There are in total 25 inputs. Four of these are non configurable are dedicated for the basic operation of all types of switches. The remaining inputs are factory programmable only.

Note: Each function can be assigned to only one input. Once an input is assigned, its status can be monitored from the Status > Inputs screen.

Input Configuration Setpoint Page



Input Table

INPUT DESCRIPTION

Access Switch Range: Disabled, Enabled Default; Disabled Changes security level to 2 from 1, when enabled.

Process Interlock A to J Range: Disabled, Enabled Default; Disabled Ten independent process interlocks A through J (abbreviated as “IL A….J” on the display) are used to provide fault or alarm actions based on a contact input.

S1 Closed Limit Switch S1 Closed limit switch. This Input is not configurable; it is permanently set to input F10. It is not shown on the INPUT CONFIG option screen but you can monitor its position on the INPUT STATUS screen.

S1 Open Limit Switch S1 Open limit switch. Permanently set to input F12. It is not shown on the INPUT CONFIG option screen but you can monitor its position on the INPUT STATUS screen

S2 Closed Limit Switch S2 Closed limit switch. Permanently set to input F11. It is not shown on the INPUT CONFIG option screen but you can monitor its position on the INPUT STATUS screen.

S2 Open Limit Switch

S2 Open limit switch. Permanently set to input F13. It is not shown on the INPUT CONFIG option screen but you can monitor its position on the INPUT STATUS screen.

Inhibit RPTCS Operation

When energized, this contact input disables the functionality of the controller. No outputs will change state when this input is turned on. This Mode is used to disable the controller when all four ATS Limit Switches are reading an OPEN state. This could be due to a contact development or wiring problem. This Mode is used to disable the controller when the Bypass Isolation Switch is Isolated. Isolating the ATS cradle separates the four ATS limit switches from the controller. This mode is used to disable the controller operation when supplied with a No- Break Bypass Isolation Switch. When the solenoid overlap interlock pushbutton is pressed on the front door, in order to manually operate the bypass handle, the RPTCS invokes this mode to freeze the ATS and prevent any nuisance operation.

Load Test X(F,T,L or K)1

Tests the non-preferred source by starting the generator, and attempts to transfer the load

Remote Load Shed LSR

If "Remote Load Shed Capable" is installed on the Maintenance page, this input may be energized to shed the ATS off the S2 position. Typically this signal is sent by remote emergency switchgear. On dual operator ATS’, if S1 is not available the ATS will move to Center Off. If S1 is available the ATS will transfer to S1.

Inhibit Xfer to S2 (Block Transfer, BTR)

When selected this function when not energized will block the transfer to S2. Typically this signal is sent by remote emergency switchgear. It usually is used to indicate that the generator bus is ready to load.

The following setpoints are available:

Slave Address

Range: 1 to 254 in steps of 1 Default: Off

- For RS485 communications, each RPTCS IED must have a unique address from 1 to 254. Address 0 is the broadcast address detected by all IEDs in the serial link. Addresses do not have to be sequential, but no two units can have the same address or errors will occur. Generally, each unit added to the link uses the next higher address starting at 1.

RS 485 Baud Rate

Range: 9600, 19200, 38400, 57600, or 115200 baud Default: 115200

- This setpoint selects the baud rate for the RS485 port. The data frame is fixed at 1 start, 8 data, and 1 stop bits, while parity is optional.

NTP IP Address - This setpoint is set to the IP address of the external clock source.

Note: Setting of the NTP IP Address will not function unless Comms Security is set to Disabled.

Ethernet IP Address

Range: Standard IP address format Default: 0.0.0.0

- This setpoint specifies the dedicated IP address provided by the network administrator.

Note: When changing the IP address, power to the controller must be cycled in order for the new IP address to become active.

Ethernet Gateway Address


- This setpoint specifies the gateway IP address provided by the network administrator.

Ethernet Subnet Mask


- This setpoint specifies the subnet IP address provided by the network administrator.



Comms OK Evaluation

- Specifies the time without comms before a trip will be generated.

Comms Failure Alarm

Range: Off, 5 to 25 step 5s Default: Off

- Specifies the time without comms before an alarm will be generated.

Note: Timing delay commences 5 seconds after a failure is detected.



System

The System screen lets the user select important system parameters, such as date and time, LED light intensity, and others.

System Trouble

For relay self-test, the RPTCS runs a series of self-tests, including data and program memory integrity and program execution watchdogs. If any of these tests fail, a self-test fault or alarm is generated depending on the value of the Self Test Action setpoint. The following setpoint is available for the system trouble element.

Self Test Action

This setpoint defines whether a self-test failure will cause a fault or an alarm.

Range: Fault, Alarm Default: Fault

LED Indicators

These setpoints allow the user to control the display characteristics of the front panel LEDs. The following setpoints are available:

Intensity

Selects brightness level (1 to 6) for Control Panel LEDs.

Range: 1 to 6 Default: 1

Screen Saver

The user can select whether or nor the screen save mode is enabled or disabled. When enabled, the screen will change to displaying a picture of the controller after being idle for five minutes. After two minutes, the pictures will disappear and the screen will go completely dark.

The Screensaver is enabled by default. If desired, the user can disable it in order to have the screen visible at all times. Russelectric discourages disabling the Screensaver in order to avoid the screen being burned-in with a screen image.



Events

The Events screen allows the user to enable or disable certain functions relating the recording of events as seen in the picture below.

AUTO/MANUAL SELECT



General

Select the Home > Setpoints > Control > General page to edit the controller setpoints. The general control screen allows the user to set up the following operating parameters:

Selection of Preferred Source: typically S1 (utility power) is the preferred power source. Auto/Manual: A transfer switch can be set up for the following types of transfers:

o Automatic (both from S1 to S2 and from S2 to S1) o Manual S1 to S2, S2 to S1 o Manual S2 to S1 Only

Preferred Source

Range: S1, S2 Default: S1

The Preferred Source is the source of power that the controller will try to connect to the load, if both sources are available. Either source 1 (generally utility power) or source 2 (generally generator power) can be selected as Preferred Source. Typically, utility power is the preferred source to power the ATS load.

The Source Available and Position LED’s on the GCP indicate green for the preferred source and red for the Non Preferred Source. These colors change with the selection.

If you momentarily change the preference selection the transfer will be halted.

Changing the change the preference selection does not reconfigure the status of all accessories unless they are designated with the terms Preferred and Non Preferred. As an example; Engine Start, BTR and Load Shed functions are always locked to the S2 source.

Commit Transfer to S2

Range: Disabled, Enabled Default: Disabled

If this option is enabled, then the switch will transfer to Source 2 once the 'Delay - Transfer to Non-Preferred Source’ timer has begun timing, even if Source 1 returns before the transfer takes place. This feature can be used to ensure that the transfer takes place, because one brief outage may be followed by another outage.

If this option is disabled, the switch will only transfer if the outage is still present when the 'Delay - Transfer to Non-Preferred Source’ timer has expired.

Depending on empirical data, the user may want to assume that either a brief outage is an isolated event or that it is likely to be followed by another outage.



If the data indicates that brief outages are isolated events, then the user should set the 'Commit Transfer to S2' to Disable. This will start the generator, but the ATS will not transfer to the “S2” source unless the outage is still present when the generator power has reached its nominal Voltage and frequency and when the 'Delay - Transfer to Non-Preferred Source' timer has expired.

If the data indicate that a brief outage will likely be followed by other outages, then the user should set the 'Commit Transfer to S2' to Enable. This will ensure that the ATS will still transfer to the “S2” source if the outage has cleared when the generator power has reached its nominal Voltage and frequency and the ' Delay - Transfer to Non-Preferred Source ' timer has begun to time. At this point you have committed to transfer.

Transition Mode Select

Range: Delayed, Closed Default: Delayed

Applicable only to Closed Transition types of ATS.

If a power outage occurs, the RPTCS controller will transfer the load to the “S2” source, once that source has become available. An interruption of power cannot be avoided in this case. However, after the utility has returned and the Time Delay to Preferred Source timer has expired, another brief power interruption due to the load transfer from one source to the other may be undesirable.

If this is the case, the switch needs to be operated in Closed Transition mode. The RPTCS controller will then ensure that power to the load is not interrupted during the re-transfer process.

Closed Transition may also be desirable for testing and exercising the switch so that power interruptions to the switch load can be avoided during the transfer.

Alternatively, the user can select Delayed Transition mode as the normal mode of operation.

Local Load Shed Mode [Auto Load Shed KW Bypass]

Range: Enabled, Disabled (Factory Accessible only) Default: Enabled

The RPTCS has the ability to Load Shed to the center off position without signals from a downstream remote Emergency Switchgear system. Source 2 (normally the generator source) can be protected with this Load Shed feature. It does this by monitoring the S2 source and insures that it stays within the desired setpoints. If the source exceeds these values the ATS will attempt to shed load from the S2 source. This can be activated by changing the parameters. These configuration options can only be accessed by the factory.

Note: Local Load Shed operations do not automatically reset back to S2 even if the setpoint recovers. There are three ways to reset a Local Load Shed condition; Allow the source to recover within the specified setpoint and then reset the condition on the Status page of the GCP. Use the Local Load Shed Reset input. If the ATS transfers back to the S1 source, the S2 generator cooldown timer expires and the source voltage is de-energized then the Local Load Shed condition will reset waiting for the next call to transfer.

With the RPCTS configured for Local Load Shed Mode you can set up the ATS to shed due to Underfrequency and Undervoltage events.

With the RPCTS configured for Local Load Shed Mode and equipped with Power metering (RPTCS Level 3 and above) you can also set up the ATS to shed due to Overpower events.

The RPTCS can be configured to either load shed off the S2 source by opening up the ATS S2 main contacts Load Shedding to the center off position or by sending trip signals to remote feeder breakers. On the Control Screen the ATS S2 Load Shed Mode has two options “CB Trip Load Shed” or ‘Local Load Shed”. Choosing “Local Load Shed” will cause the ATS itself to shed off the S2 source. Choosing “CB Trip Load Shed” will allow you to configure an output to operate a relay and trip downstream circuit breakers and therefore unload the S2 source.



Underfrequency Set’ on the Settings > Operations > S2 Set screen from OFF to a valid frequency set point, as shown in the Operation Setpoints Table 8.4.2 above. For example, the user could enter a value of 59.0 Hz as the trigger point for the Load Shed feature.

Once a valid set point has been entered, as noted in the Operation Setpoints Section above, the user will be presented with three more entry fields, “S2 Local Load Shed Underfrequency Delay”,” S2 Local Load Shed Under Voltage Set”, and “S2 Local Load Shed Overpower Set”, with the allowable ranges.

For example, the parameters could be set up as follows:

S2 Auto Load Shed Underfrequency Set 59.0 Hz

S2 Auto Load Shed Underfrequency Delay 3s

S2 Auto Load Shed UnderVoltage Set 95%

S2 Auto Load Shed Overpower Set 103%

In the example above, the Auto Load Shed output will be triggered when the frequency falls below 59.0 Hz for more than 3 seconds, when the Voltage drops to less than 95% of nominal, or when the power of the switch increases to 103% of nominal. If this output is used to trip a downstream load breaker, a part of the load fed by the switch can be shed in order to stabilize the generator and keep the system from failing due to overload.

If desired, the user can also bypass the load shedding due to a KW overload condition. To accomplish this; the ‘Auto Load Shed KW Bypass’ parameter on the Control Screen is changed from ‘Disabled’ to ‘Enabled’. The output will remain energized until the user manually clears the Load Shed on the Status screen of the controller.

The Local Load Shed Mode, Local Load Shed KW Bypass, and Local Load Shed Reset accessory functions can be added and controlled by hardwiring inputs to further customize local load shed operations.

Local Load Shed Reset -This is an input that allows a manual reset when the setpoint recovers. The user can also reset the condition on the Status page of the GCP.

Local Load Shed kW Bypass - This is an input that allows a manual bypass Local Load Shed kW Bypass operation. The RPCTS must be configured for Local Load Shed Mode and equipped with Power metering (RPTCS Level 3 and above).

CB Trip Load Shed - This is the alarm output that is used to send trip signals to remote feeder breakers. On the Control Screen the ATS S2 Load Shed Mode has two options “CB Trip Load Shed” or ‘Local Load Shed”. Choosing “Local Load Shed” will cause the ATS itself to shed off the S2 source. Choosing “CB Trip Load Shed” will allow you to configure an output to operate a relay and trip downstream circuit breakers and therefore unload the S2 source.

ATS S2 Load Shed Mode - Used in conjunction with “CB Trip Load Shed” mode. This is an input that when on allows the user to utilize both CB Trip Load Shed and the Load Shed to the center off position feature.

Load Shed - This is a control output that is used to annunciate the status of Remote Load Shed operation.

Remote Load Shed -This is the standard input signal from a downstream remote Emergency Switchgear system.

Note: If either the hardwired user configurable input or the selector on the control switch has been set to ‘Local’, the ATS will disconnect from the S2 power source when the controller detects an local Load Shed condition. In order to have the local Load Shed trip a downstream breaker, the mode selector on the Control screen has to be set to ‘Remote’ and the hardwired input (if configured by user) has to be OFF.

Note: Great care has to be used by the customer to properly apply the Auto Load Shed feature in order to avoid unintentional power loss to the switch load.



Sync Phase Angle Limit

Range: OFF, 0° to 20° Default: 10°

With this variable, the user can select the allowable phase angle difference between Source 1 and Source 2 in order for a transfer to take place.

Note: The Sync check function cannot be disabled on closed transition switches. The off setting is equal to 0°.

Note: The Sync check function can be turned off on open transition single operator switches (See accessory SCF on accessory page). When off is selected the in phase monitor is not used and the transfer switch will transfer immediately in an open transition mode.

Slip Rate

Range: 0.00 to 0.20 Default: 0.20

With this variable, the user can select the allowable maximum allowable frequency difference in order for a transfer to take place.

Inhibit Transfer to S1

Range: OFF/NO, ON/YES Default: OFF/NO

This has the same function as the Inhibit Transfer to S1 input.

Maintain S2

Range: Enable/Disable Default: Disable

When selected this function will maintain the S2 position even if there is a load shed or loss of the S2 source.

This Mode can also be controlled using hardwired inputs.

Dependency: If ATS is configured for Auto/Manual or Manual operation only

Enable S1 Sag Timer

Range: Enable/Disable Default: Enable

S1 Sag Timer Disable

With the ATS load connected to the S1 Source, and with S2 available if the S1 source momentarily sags or swells beyond the limits, the Controller attempts an immediate transfer back to the good S2 Source. The inherent delay of sensing this sag is less than 250 msec. The User can choose to add delay to this process by increasing the S2 Sag Timer in 100 millisecond increments.

S1 Sag Timer Enable

When the ATS is closing back onto the S1 source it takes 250msec for the sag function to operate and turn on. If there is a power quality disturbance on the S1 source caused by the oncoming load at the precise moment the main contacts close it is possible that this will be seen as an S1 failure and the ATS will attempt to retransfer back to the good S2 source. By enabling this timer the Sag timer function it will always be on even before the S1 contacts are closed and provide the maximum protection.

Enable S2 Sag Timer

Range: Enable/Disable



Default: Enable

S2 Sag Timer Disable

With the ATS load connected to the “S2” Source, and with the Time Delay to the Preferred Source Timer timing, if the “S2” Generator momentarily sags or swells beyond the limits, the Controller attempts an immediate retransfer back to the good “S1” Source. The inherent delay of sensing this sag is less than 250 msec. The User can choose to add delay to this process by increasing the S2 Sag Timer in 100 millisecond increments.

S2 Sag Timer Enable

When the ATS is closing into the S2 source it takes 250msec for the sag function to operate and turn on. If there is a power quality disturbance on the S2 source caused by the oncoming load at the precise moment the main contacts close it is possible that this will be seen as an S2 failure and the ATS will attempt to retransfer back to a good source. By enabling this timer the Sag timer function it will always be on even before the S2 contacts are closed and provide the maximum protection.

Modbus Control Override

Range: Enable/Disable Default: Disable

If a remote user is manipulating Modbus Registers for various control features and then communication with the RPTCS is lost the Modbus Register will not reset and the ATS will be stuck in whatever mode the remote user commanded it to. By momentarily pressing enable all remote Modbus register will be reset back to their default settings.

Example: A remote user accesses the proper address to command the RPTCS to start the engine/generator. The remote user’s computer then fails which will leave the engine/generator running indefinitely. Pressing and resetting the Enable will override all Modbus Control addresses back to the original state and the engine generator will shut down.

When the Modbus Control Overide is left Enabled all Modbus Registers will be constantly reset. This will block all unwanted remote users from tampering with the RPTCS control and operation.

Manual Xfer (Manual Mode Operations)

Range: Auto, Man Xfer, Man Xfer to Pref Default: Auto

The ATS itself needs to be configured as an Auto/Manual ATS in order to access any of the following Manual operations.

Automatic: In Automatic mode the RPTCS will automatically control all load transfers from S1 to S2 or from S2 to S1.

Man Xfer (Manual Transfer Mode): Selecting this Mode places the ATS into the Manual Mode. In this Mode, the Controller cannot automatically initiate a transfer due to a Source failure, Load Shed Signal or Load Test. In order to transfer the switch, the Operator can use the appropriate “S1”>”S2” Soft Key or “S2”>”S1” Soft Key. Optional External Pushbuttons may be installed to perform the same function as these Soft Keys.

Manual Mode can be used to stop a transfer sequence before it starts. Manual Mode cannot be used to place the ATS into the Center Off position Manual Mode cannot be used to stop a transfer sequence once it is in the Center Off

position. If the soft keys are pressed to initiate a manual transfer the user can stop this sequence

from occurring by pressing the alternate soft key. This must be done before the first set on main contact is operated.



Maintain S2 with Man Xfer Mode: In addition to the manual control operation, the Operator can also select to Maintain S2.

When selected this function will maintain the S2 position even if there is a load shed or loss of the S2 source. When this feature is selected, the ATS will not transfer out of the S2 position under any condition; pressing the “S2”>”S1” Soft Key will have no effect.

To select this feature, use the Control Screen. This feature will only be available when the system is in either Manual Mode. Enabling this feature turns it ON, disabling OFF.

Optional External Pushbuttons may be installed to perform the same function as this control feature.

Man Xfer to Pref (Manual Transfer to Preferred Source): In this Mode, the Controller automatically transfers from “S1” to “S2” for a power outage or load test. When the “S1” Source once again becomes available or the load test is reset, the Controller does not initiate a retransfer. In order to retransfer, the Operator uses the S2>S1 Soft Key, or External Pushbutton (if supplied). While waiting for the Soft Key or Pushbutton to be actuated, if the “S2” Source fails or receives a Load Shed Signal, the Controller automatically sneaks back to retransfer the load to the good “S1” Source.

Maintain S2 with Man Xfer to Pref Mode: In addition to the Man Xfer to Pref operation, the Operator can also select to Maintain S2.

When selected this function will maintain the S2 position even if there is a load shed or loss of the S2 source. When this feature is selected, the ATS will not transfer out of the S2 position under any condition; pressing the “S2”>”S1” Soft Key will have no effect.

To select this feature, use the Control Screen. This feature will only be available when the system is in either Manual Mode. Enabling this feature turns it ON, disabling OFF.

Optional External Pushbuttons may be installed to perform the same function as this control feature.

Security Levels

Three security levels above the default level are recognized. Each security level can also be set for passcode access. The passcode is programmed as a five-digit number, using only digits 1 through 5. The security access levels are:

Level 1 Security (default passcode is 11111): This security level allows user access to: - \Exerciser\All parameters - \Setpoints\Config\System\All parameters - \Setpoints\Config\Waveform\All parameters - \Setpoints\Config\Datalog\All parameters - \Setpoints\Operation\All parameters - \Setpoints\Control\Alarms - \Setpoints\Security\Passcode Level 1

Level 2 Security (default passcode is 22222): This security level allows user modifications to: - \Diagnosis\Events\Clear - \Diagnosis\Stats\Clear - \Setpoints\Config\ATS\All parameters - \Setpoints\Config\Comms\All parameters - \Setpoints\Control\General\All parameters - \Setpoints\Control\ManXfer - \Setpoints\Security\Passcode Level 2 - \Setpoints\Security\Comms Security

Level 3 Security access is for Russelectric factory use only. For reference, this level allows modifications to:

- \Setpoints\Config\CT-VT\All parameters - \Setpoints\Config\Inputs\All parameters - \Setpoints\Config\Outputs\All parameters - \Setpoints\Config\Maint\All parameters - \Setpoints\Security\Passcode Level 3 - \Setpoints\Security\Access Switch Level - \Setpoints\Control\Interlock

The system passcode can be entered at any time by a sustained press on the ENTER key. This displays a dialog box prompting for a new passcode. Alternatively, the system passcode can be entered by pressing a currently unauthorized (grayed-out) control/selection key. This will display an error message detailing the required security levels and whether access switch or passcode entry is required. If only a passcode is required to complete the control/selection, the error message displays a passcode entry dialog box.

Passcodes are automatically canceled after five minutes of inactivity. The system passcode access can also be canceled by a sustained press on the ESC key, which clears any previously entered passcode. Communications passcode access can be cancelled by writing zero to the passcode register.



The following system security setpoints are programmed in the security page.

Passcode Level 1, Passcode Level 2, Passcode Level 3 Range: any five-digit number using digits 1 through 5 only or Disabled Default value: 11111 (level 1), 22222 (level 2)

Access is granted if a passcode has been correctly entered matching the value of this setpoint. Note that Level 3 is for factory personnel only.

Access Switch Level Range: 1, 2 Default value: 1

Sets the access level provided by the access switch being closed. The contact input for the access switch is configured on the contact inputs page.

Comms security Range: Enabled, Disabled Default: Disabled

Sets whether the security feature applies to the communications ports.

NOTE: Setting of the NTD IP Address will not function unless Comms Security is set to Disabled.

Events

The Home > Diag > Events page displays up to 256 events (Minimum Event Sensing Duration: 100 msec).

When this page is selected, the controller will load and format an event list of the ten most recent events from the event recorder, as shown in Figure 11.2.2. The most recent event is placed at the top of the list, with the oldest event at the bottom.



If a new event occurs while viewing the event page, the event list will automatically reorganize it self and place the newest event first. The addition of new events while the event list is being viewed will not reset the event screen to the top of the page unless the newest event is being viewed. If there are no events in the event recorder, then this page will be empty.

Individual events are selected by using the UP and DOWN keys to highlight the event then pressing the ENTER key. This will display a pop-up window with the event details.

Statistics

The Home > Diag > Stats page displays date and time information as well as the reason for the last failure of the preferred source. It also contains information about how long the load has been in either source, how many transfers have occurred, and the total time the load has been without power. All this data is accumulative and can be reset by pressing the CLEAR soft key.

Phasors

The Home > Diag > Phasors page displays phase rotation, Voltages and angles, frequency, and phase difference for both sources. Below shows a typical screen for a 240V, 3-phase system. In this example, both sources are on an ABC rotation with an actual phase angle difference of 1.3 degrees. The frequency differential (slip rate) between both sources is ensuring that the phase angle will be driven towards 0 during the synchronization period. If the resulting phase angle difference becomes less than 10° (factory default), the controller will allow the switch to transfer.

This page also features a status message that will inform the operator about the lead status of one power source with respect to the other power source. When the phase angle is less than 3°, the message changes ‘S2 In Sync w/ S1’.



Product Information

The Home > Diag > Info page displays fixed system information, including the order code, serial number, hardware revision, software revision, modification number, boot revision, boot modification, original calibration date, and last calibration date.

Reports

The Home > Diag > Report page displays additional information on the last transfer event and the load conditions at that time.



Waveform

The Home > Diag > Waveform page displays information regarding the date and time of the waveform capture as well as the event that triggered it.

The setup for the wave form capture is performed on Home > Diag > Waveform.

SECTION 11 Exerciser Page 110 of 125

SECTION 11 Exerciser The RPTCS has a built-in exerciser that can be enabled and set up from the Exerciser\Info screen. This feature allows the user to test the system periodically or to setup a schedule for operating the system periodically in order to minimize utility costs.

Information Screen

From Excerciser > Info screen the operator can access all required setup parameters for scheduling exercises. It also indicates as to when the last exercise took place and when the next exercise will be performed.



Setup

The Home > Exercise > Setup page displays the RPTCS Exerciser parameters as shown below.

Exercise type and schedule can be selected on the Excerciser > Setup screen as seen above. The mode of operation of the exerciser function can be selected with a time base of 1 day, 1 week, 14 days, 28 days, or 365 days. With a time base of 365 days, up to 24 events can be scheduled. With all other time bases, the number of exercise events is limited to 7.

For each exercising event, the operator enters a start time as well as a duration. The exercise duration range is 0 to 60 minutes. In addition, the operator can select the type of exercise as ‘Genstart and Transfer’ or as ‘Genstart only’.

NOTE: Do not program two or more CDT events for the same time.

When the ‘Gen Start only’ mode is selected, the controller will start the engine, but does not actually transfer the load. In this mode, the readiness for the engine generator set is tested. It does not test the functionality of the automatic transfer switch itself.

In the ‘Gen Start and Transfer’ mode, the controller starts the engine and actually transfers the load to the alternative source. This mode can be used to test the integrity of the emergency power system. It can also be used to setup a schedule for times of operation when the switch load will run on an alternative power supply. This could be done, e.g., to avoid power demand charges from a utility company.

If the operator chooses to abort an ongoing test, there is a ‘Test Cancel’ button on the Exerciser > Info screen. This screen also contains a ‘Test’ button that will take the user directly to the Test screen.

Test

The Test page can be accessed by pressing the green Test button located on the front of the graphical display. It can also be accessed from the Home > Exerciser > Test page.

This page displays the RPTCS system test choices, as shown below. From the Test screen the user can perform the same operations as performed by the exerciser. Whereas exercises are performed automatically, a Test always has to be initiated by the user. The user must be logged in with the appropriate pass code to perform any of these tests.

There are four types of test: Xfer Load, No Xfer, Peak Shave and LED Test. The screen also provides an ‘End’ button to abort any of the two test types. Once any of these modes are active, a yellow banner highlights the selection.



Xfer Load

In order to simulate a load transfer as if an outage was occurring, the operator can select the Xfer Load test. With this test type, the engine will start up and the load will transfer according the Engine Start Time Delay followed by the Time Delay to Non-preferred Source. When the test is ended by depressing the END button, the switch will go through the Time Delay to Preferred Source before actually transferring back to the utility.

NOTE: Once a Xfer Load command has been issued and the alternative source has reached an acceptable level of voltage and frequency, the test cannot be aborted. If the user tries to end the test at this point, the load will still be transferred to the alternate source, but the return sequence will immediately activated.

No Xfer

For testing the functionality of the engine generator set only, the operator can initiate a NoXfer test. In this case will engine will start up, but the load will not be transferred.

Peak Shave

A peak shave test is very similar to a Xfer Load test except that during the retransfer to the preferred source the transfer to preferred source time delay is temporarily reset to five seconds. This allows the operator to quickly retransfer back to the preferred source when the peak shave test is ended.

LED Test

Pressing this button flashes all of the LEDs that are on the front of the graphical display.

Test Mode and Fail to Transfer

If the ATS cannot successfully retransfer back to preferred position due to mechanical or electrical control issues it will seek the non preferred source to reenergize the loads. The fail to transfer logic invokes the Test mode to keep the ATS in this position until the ATS can be properly inspected.

Two-position lever-operated selector switch with the following positions: (A) NO-COMMIT TO TRANSFER OPERATION & (B) COMMIT TO TRANSFER OPERATION, in the event of a Source 1 power failure. As noted in Section 8 above, whenever the Source 1 fails, various adjustable timers delay the start of the engine generator, and then delay the transfer of the switch to the generator (Source 2). In the NO COMMIT position, if Source 1 returns and is within all limits prior to the initiation of the Transfer to Source 2 operation, the transfer sequence is not performed and the transfer switch remains in the Source 1 position. In the COMMIT position, even if Source 1 returns prior to the initiation of the Transfer to Source 2 operation, that transfer sequence is still performed and the transfer switch will remain in the Source 2 position for the times described in Section 8 above. Includes (1) Legend plate marked: "NO COMMIT" - "COMMIT" & (1) Nameplate marked: "TRANSFER MODE SELECTOR SWITCH".

Function

LSR Load Shed Circuit (Internal)

Local Load Shed Circuit (Internal)

Internal Load Shed function energized by a remote 24VDC will shed the load off S2 source. Typically this 24VDC signal is sent by remote emergency switchgear to a designated input. It usually is used to indicate that the generator bus is overloaded.

The RPTCS has the ability to Load Shed without signals from a downstream remote Emergency Switchgear system. Source 2 (normally the generator source) can be protected with this Load Shed feature. It does this by monitoring the S2 source and insures that it stays within the desired setpoints. If the source exceeds these values the ATS will attempt to shed load from the S2 source. See page 90 for a full description. This can be activated by changing the parameters. These configuration options can only be accessed by the factory.

After the status lights are checked to see if the desired bypass source is available, the pushbutton is pushed and held to energize the solenoid while the bypass lever is moved to the desired source. Includes (1) Nameplate marked: "SOLENOID INTERLOCK PUSHBUTTON".
