SECTION 1

INTRODUCTION TO THE QUANTUM™ EVAPORATORCONTROL SYSTEM


090.610-O (MAR 2016)Page 6

The Operator Interface Panel (we will call it the In-terface Panel throughout the rest of this guide) is the central point of the system, whereby all Remote Zone Interface Panels are attached. It can easily be identi-fied by the presence of a display screen and a keypad. The Interface Panel monitors and controls all of the Remote panels that are attached to it, through RS-485 serial communications (to be explained later).

The Interface Panel runs the actual program that provides the control for the entire system. Through communications, it monitors the status of each attached Remote Zone Interface Panel, and provides the necessary control instructions for each Remote Zone Interface Panel to perform. Additionally, all setpoints are stored in the Interface Panel.

Status of the entire system may be monitored form here, and appropriate changes made to system operation.

THE REMOTE I/O PANEL

Each complete Evaporator system will have from one to ten Remote I/O Panels, and each panel is capable of controlling up to 3 Evaporator zones:

Quantum LX Evaporator

Remote Panel Number: ___________

Notice that there is a yellow sticker on the front of the door for each Remote I/O Panel. This sticker will identify the Remote Panel number and the Zones it will control. This will all be explained in greater detail later, but it is an important fact to note.

The Remote Panels do not have a display or keypad. Each Remote Panel can control three independent Zones. Each Quantum™ LX Evaporator system can manage up to 10 Remote I/O Panels, providing the ability to control as many as 30 Evaporator zones.

SETUP DESCRIPTION

The following Setup Guide is meant to assist the installation technician in making all necessary electrical power, control and communications connections to a Quantum™ LX Evaporator system. They will be provided also with the basic information necessary to login and configure the system. It will then aid in troubleshooting the system should problems arise. This Guide will help to ensure:

WIRING

• Location of incoming AC source power to all panels (Interface and Remote)

• Basic installation guidelines are followed.• Location, polarity and grounding of

communications wiring.• Location of all control (I/O) wiring.• Proper powering up of all panels.

CONFIGURATION

• Logging into the system.• Verifying communications.• Configuring the Zones.• Calibrating sensors.• Setting up operating Setpoints.

OPERATION

• Setting the operating Mode.• Verifying the data being returned to the Interface

panel from all remote panels (Zones).• Checking and clearing of alarms.• Zone overview• Ammonia Configuration

IDENTIFYING AN EVAPORATOR SYSTEM

A minimum Evaporator system will include one Operator Interface Panel and one Remote I/O Panel.

THE OPERATOR INTERFACE PANEL

Each complete Evaporator system will have a single Operator Interface Panel, as shown below:


090.610-O (MAR 2016)Page 7

EVAPORATOR SYSTEM CONFIGURATIONS

As stated before, each complete Evaporator system will consist of one Interface Panel, and can at least one Remote I/O Panels Each Remote Panel can control up to three zones.

SYSTEM INSTALLATION

An in depth installation setup is beyond the scope of this guide, however some basic rules can be observed:

▯ Pay particular attention to the yellow sticker on the front of each Remote I/O Panel. It will have been filled in at the factory, as to which panel will control which zone. This is a close-up of the sticker:

Quantum LX Evaporator

Remote Panel Number: ___________

Zone: ___________

Zone: ___________

Zone: ___________

▯ Maintain a total distance of 2000 feet or less between the Operator Interface Panel, and the very last Re-mote I/O Panel on any one communications cable run. As will be explained later, it is possible to have two separate communications cable runs, depending upon the total number of Remote I/O Panels. Keep in mind that neither of these cable runs can exceed 2000 feet in length.

▯ Remote I/O Panels should be mounted in close prox-imity to the zones that they will be controlling. In some instances, there may be fan motor starters lo-cated in a separate area from the zone, so it may be more convenient to locate the Remote I/O Panels near the starters, than the actual Evaporator unit. The

idea is to minimize the length of the control wiring, so if there is less wiring to the zone than to the starters, then install close to the starters or vice-versa.

▯ The system is capable of Ethernet communications, this may be something to consider when placing In-terface Panels, as you would want a nearby Ethernet connection to be available.

▯ Keep all communications wiring in a separate conduit from control wiring.

▯ When wiring for communications, it is important to ground only one end of the communications cable. This ground will be located in the very last Remote Panel of each communications cable run. If the com-munications were to be grounded at both ends, then it would be possible for ground loops to develop, which could impair communications between panels.

▯ Interface Panels should be located in easy access ar-eas, and should be mounted at eye level for screen viewing.

▯ Remote Panels are rated for both indoor and outdoor use. Although access to the Remote Panels will be rare after installation and setup, it is still advanta-geous to keep them accessible for potential mainte-nance situations (reasonable lighting, sufficient door swing, etc.).

▯ Install all panels within a convenient distance of a power source.

▯ Refer to the Zone Configuration Chart for additional information.


090.610-O (MAR 2016)Page 10

CHECKING THE AC POWER

Interface Panel

▯ Ensure that the Control Power switch is in the OFF position.

▯ Energize the 120 Volt circuit at its source.▯ Using a DVM, measure the voltage at the AC

power terminal strip. Ensure that you read ap-proximately 120 VAC between Hot and Neutral, and Hot and Ground. There must not be voltage between Neutral and Ground.

▯ Once the incoming voltage has been verified, turn the Control Power switch to ON.

▯ On the enclosure door, and watch the Quantum™ LX controller (on the backside of the door). You should notice various LED’s blinking or flashing.

▯ Watch the display on the front of the door. Af-ter a short period of time, you should notice the display showing a boot sequence. Various text messages will be shown as it proceeds with the boot-up process. When finished, a screen similar to the following image should be visible:

▯ If the panel has reached the point of showing the above screen, the boot process was successful. Turn OFF the Control Power switch, and De-en-ergize the 120 Volt circuit at its source.

▯ If the panel does not reach to the point of show-ing the above screen, then troubleshooting will be required. Refer to end of this guide entitled Troubleshooting.

Remote Panel(s)

▯ Unlike the Interface Panel, the Remote panels do not have an external power switch. Instead, the enclosure will contain two HOA (Hand-Off Automatic Modules). These modules allow the technician to override control signals, by manu-ally energizing components. An example of one of these modules is shown here:

Red, power OFF tab

Black, power ON plunger

▯ Notice in the above pictorial, there is a Red pow-er OFF tab, and a black power ON plunger. These items are located on a circuit breaker for each of the two HOA modules. Together, they act as the Control Power switch.

▯ Push each of the Red power OFF tabs down. The Black power ON plunger should pop up. If the plunger does not pop up, then the power was already off. Do this to both HOA modules.

▯ Energize the 120 Volt circuit at its source.

▯ Using a DVM, measure the voltage at the AC power terminals (1, 2 and PE). Ensure that you read approximately 120 VAC between Hot and Neutral, and Hot and Ground. There must not be voltage between Neutral and Ground.

▯ Once the incoming voltage has been verified, push in the Black power ON plungers of both HOA modules.

▯ To the right of the HOA modules are several I/O boards. There will be at least one Digital board (recognizable by the plug-in I/O modules), and one Analog board. Inspect all boards for the presence of flashing, blinking or steadily lit LED’s. If LED’s are lit on all boards, then power has been properly applied.

▯ If LED’s are not lit on all boards, then refer to the section entitled Troubleshooting.


090.610-O (MAR 2016)Page 11

WIRING FOR COMMUNICATIONS

NOTE: Refer to the next sections entitled ZONE CON-FIGURATION CHART and EVAPORATOR SYSTEM COM-MUNICATIONS WIRING DIAGRAM, for additional infor-mation about how the system is configured.

Interface Panel

Depending upon the number of Remote Panels that have been installed, there could be up to two dif-ferent communications cables run to the Interface Panel. One of these cables would feed Remote I/O Panels 1 through 5, and a second cable would feed Panels 6 through 10. The incoming RS-485 commu-nications cable(s) will be a two-conductor, shielded type. Frick Controls recommends the use of Belden #9841 or equal.

Wiring for 1 to 5 Remote Panels

For systems that have between 1 and 5 Remote Panels, use the following wiring procedure:

▯ Open the panel door.

▯ On the inside of the enclosure door, you will find the Quantum™ controller, and a communications terminal block. No-tice that there are two wires that con-nect from the left side of the terminal block, to the Quantum™ (Comm. 4). These are the internal TX / RX commu-nications wires. You will be connect-ing the external field communications wires to the other (right) side of these terminals.

▯ Take the end of the incoming commu-nications cable, and strip about 2 inches of insulation from the end.

▯ Clip the shield wire back even with the insulation, and either use heat shrink tubing to cover the area, or electrical tape. This will help to ensure that any strands of the shield that may be ex-posed don’t come into contact with any live voltage areas of the panel.

▯ Strip the end of each of the two re-maining conductors back about ¼ of an inch. Generally there are only three color combinations available depending on the type of cable used. There will be either a black and white/clear insulated wire, a red and white/clear insulated wire, or a red and black. Either way, one of the wires should be black. Take the black wire and insert it into the top position of the terminal block (labeled as –TX/RX).

▯ Take the remaining wire (white/clear or red) and insert it into the second posi-tion down from the top of the terminal block (labeled as +TX/RX).

▯ It is very important that the colors of these wires follow this same polarity scheme throughout the daisy-chaining process to all panels.

▯ Refer to the Zone Configuration Chart later in this guide to verify dipswitch settings.

Wiring for 6 to 10 Remote Panels

For systems that have Remote I/O Panels 6 through 10, use the following wiring procedure:

▯ Open the panel door.

▯ Follow the same guidelines for insu-lation and wire stripping as described earlier.

▯ For Q5 board installation, skip this step. On controllers that have the Q4 board, there is a DIN rail mounted below the incoming power strip. On the DIN rail is mounted a RS-232 to RS-485 com-munications converter module (Comm. 3), and a power supply. Both of these components have been pre-wired at the factory. All that is left to do is con-nect the field connections. Refer to the following pictorial for connections:

TX/RX+ TX/RX-

▯ For Q5 board units, skip this step. For Q4 board units, Insert the black wire into the top of the module in terminal position 4, and the white/clear or red wire into position 6, as shown above.


090.610-O (MAR 2016)Page 12

▯ For Q5 units, connect the Comm-3 communications wires directly to the appropriatly labled Comm-3 terminal strip.

▯ This should complete the Interface Panel communications wiring.

▯ This should complete the Interface Panel communications wiring.

▯ Refer to the Zone Configuration Chart later in this guide to verify dipswitch settings.

Remote Panel(s)

Follow the same description for wire stripping as with the Interface Panel, with the exception that the shield wire does NOT get trimmed off.

▯ On Evaporator systems with only one Re-mote Panel, the only communications cable that you will have is that which comes di-rectly from the Interface Panel.

▯ Insert the stripped end of the black wire into the terminal marked TX/RX-, and the white/clear or red stripped wire into the terminal marked TX/RX+, and the shield wire into the Ground terminal as shown (the Ground terminals may be identified by their Green/Yellow color).

TX/RX-

TX/RX+

Shield

▯ On Evaporator systems with more than one Remote panel, the first Remote panel will have two communications cables; the first will be from the Interface Panel, and the sec-ond will be going to the next remote panel.

Functionally, it does not matter which cable is which, as long as the polarity of both is observed. NOTE: It would be a good idea at this time however to label each of the two cables as to where they are going for future maintenance / troubleshooting use (refer to the yellow sticker on the front of each Re-mote Panel for the panel numbers).

▯ Insert the black stripped wires from both cables to the TX/RX-, and the white/clear or red stripped wires into the terminal marked TX/RX+. Both shield wires should be twisted together, and then taped to prevent them from touching any live surfaces. The shield wires DO NOT get connected to any termi-nals.

▯ Follow this procedure for all Remote Panels, except for the very last one. This panel will have only one communications cable (label it also), which will be coming from the pre-vious panel. The connections for this cable are the same as that for a single Remote Panel, that is, the shield wire must be at-tached to one of the Ground terminals.

▯ NOTE: Only the last Remote Panel should have the shield wire grounded (terminated).


090.610-O (MAR 2016)Page 13

ZONE CONFIGURATION CHART

The following table is to be used to set the System configura-tion. The following page then shows a pictorial representa-tion of how this chart applies to a full system. The columns indicate:

• INTERFACE COMMUNICATIONS PORT

• COMM. 4 – This is an RS-485 serial port physi-cally located on the Q4 controller, or on the Q5 Interface (within the Operator Interface Panel). This signal can directly feed all attached Remote Panels (up to 2000 feet total distance). This port provides communications to the digital and an-alog boards within Remote Panels 1 through 5 (zones 1 through 15)

• COMM. 3 - On the Q4 controller, this is an RS-232 serial port physically located on the Q4 con-troller (within the Operator Interface Panel). This signal requires conversion to RS-485 to meet the distance requirements of the system, so a

converter module has been installed to provide this conversion (provides up to 2000 feet total distance). On the Q5 controller, this port is lo-cated on the Interface board. This port provides communications to the digital and analog boards within Remote Panels 6 through 10 (zones 16 through 30)

• PANEL # - This number identifies each Remote Panel as a discrete device, similar to an address. Each Panel can control up to 3 zones.

• ZONE # - This number identifies each individual zone in the system. It is this value that will ap-pear on many of the Interface Panel screens to describe the zone that is being viewed.

• BOARD # - This lists the available analog and digital boards within each zone.

• DIPSWITCH # - This shows the settings of how each dipswitch must be configured to recognize the appropriate I/O board.

VERIFYING COMMUNICATIONS

The first step in verifying communications is to view what I/O boards have been detected by the Interface Panel. This infor-mation will appear on the About screen, shown here:

Review the information that is shown in the Analog and Digital Board areas of the screen. Compare what is shown against what is actually installed.

NOTE: This screen does not update (refresh) automati-cally. To see any new or different information that may occur, you must access a different screen, then come back to this one to see any new data.

The analog board area of the screen can list up to the ten possible analog boards that are allowed, and they are listed in a single column. In the digital board area, you will notice that there are two columns. The left hand column represents Panels 1 through 5 (and digital boards 1 – 10), and the right hand column represents Panels 6 – 10 (and Digital boards 1 - 10). Refer to the Zone Configuration Chart and the Evaporator System Communications Wiring Diagram for clarification.

Compare what is displayed here with what is actually installed in your system. If a board is physically installed in a Remote Panel, yet does not show up on this screen, then find the Panel that the board is located in, and visually check the RX and TX LED’s on the board. These LEDs should be flashing. The RX LED will be flashing much faster than the TX LED, but neither should be off completely, as this indicates a potential wiring problem.

Start by verifying that the boards within Remote Panel 1 are correctly being detected. Then move on to the next panel, and so on, for each of the two potential communications branches (Comm. 3 and Comm. 4). If Remote Panel 1 shows correctly, but there is a problem with Remote Panel 2, then do nothing with the wiring up to and including Panel 1. Inspect instead Panel 2 for proper communications polarity and connections. A good indication that you have wires backwards (reversed) would be that the RX LED is on solid within the suspect panel. If wiring WAS found to be incorrect, make the correction, and then access the Communications screen by selecting Configu-ration from the Main Menu, then Communications.

On the Communications screen shown above, use the [Tab] key to select Redetect IO Comms and press [Enter]. This will cause the Quantum™ LX controller to reinitiate all com-munications with the system. After Redetecting IO Comms, wait about 30 seconds, then access the About screen once again. If the wiring issue has been corrected, the questionable I/O board should now be listed, and the RX/TX LED’s for that board should be flashing normally.

If the boards for Remote Panel 2 are now properly detected, then move on to Panel 3, etc.

When all installed boards have been detected, then the basic setup is complete. You can now move on to configuring the system operating parameters.


090.610-O (MAR 2016)Page 18

The Alpha screen shows a graphic representation of the numerical keypad. The symbols that appear above each key on this screen are the possible combinations of sym-bols that are associated with the digital portion of the key.

As an example, suppose that you wanted to modify the text line in the screen example shown. You want to change the line from reading Auxiliary Analog 1, to Zone 1. The first thing you would do, is to use the [Backspace] key on the keypad to position the cursor (blinking vertical line), to the far left side of the text. Notice as the cursor backspaces, it erases the current line of text.

Press the number [3] key (notice that the capital Z is one of the symbols in the line right above the [3] key). A capi-tal Y will appear in the Current Character box. Continue to press the [3] until the capital Z appears there. Now press the [Up Arrow] key, and notice that the Z has been placed on the text line in the first position.

Next press the [6] key on the keypad, and continue press-ing it until the small o appears in the Current Character box. Press the [Up Arrow] key to place the o on to the text line. Continue entering text until you are satisfied with the changes that you have made, press the [Enter] key to accept them, and you will be returned to the pre-vious screen. Once all zones names have been entered, press the [Submit] key.

NOTE: If many fields need to be renamed, the user can plug a computer keyboard into the following locations:

• For the Q4 controller - Use PS2 style plug, and use the socket labeled PL7.

• For the Q5 controller - Use a USB compat-ible keyboard, and plug it into one of the two available USB connections.

ZONE CONFIGURATION

Zone Configuration is the process of setting the operating pa-rameters of each of the installed zones.

• Global Zone Configuration – Use this screen to enable or disable each independent zone. NOTE: If a zone is installed, it MUST be enabled before it can be setup and accessed. The screen also allows you to custom name each zone.

• Current Zone Configuration –Once the Global Zone Configuration has been setup, use this screen to set-up the parameters for each of the individual zones (1 -30).

Global Zone Configuration

Access this screen from the Main Menu. Select Configura-tion, then Global Zone Configuration. The following screen will appear:

Each Evaporator zone that is in use should be set to En-abled. The Global Zone configuration screen also provides the ability to supply a unique name for each zone. After moving the cursor to one of the Name fields, press the Up Arrow key to access an alpha/numeric data entry screen, as shown here:


090.610-O (MAR 2016)Page 19

Current Zone Configuration

Access this screen from the Main Menu. Select Configuration, then Current Zone Configuration. The following screen will appear:

Notice in the upper right hand corner of this screen is a set-point box that contains a value. You may change the value in this box to the number of the zone that you wish to configure. You must then press the [Submit] button for the screen to dis-play that zone. In the above example, the number 1 is shown on the box. Notice that right below the setpoint box, the words ZONE #1 is displayed, so Zone 1 is the zone parameters that are being shown.

Many other screens also show the Zone selection box in the upper right corner. Any screen that displays this box presents data that pertains exclusively to the selected zone. The selec-tions on the Current Zone Configuration page must be made for each Evaporator zone that has been enabled on the Global Zone Configuration page.

The Current Zone Configuration page permits the user to en-able any four control functions:

• Cooling• Defrost• Dehumidification• Heating

The Options section allows the user to configure various me-chanical aspects of the system, which include the type and operation of valves as well as the fan type.

CALIBRATING SENSORS

Each temperature or humidity sensor in the Evaporator should be calibrated before the system is put into operation.

Access this screen from the Main Menu. Select Calibration, then Analog Inputs:

The process used for establishing calibration values is rela-tively simple. It will however require a container of ice water or an infrared digital temperature probe.

First, establish the temperature for a specific zone’s tempera-ture sensor. If a digital infrared measurement device is used, simply enter the calibrated temperature into the Current Value box and press [Submit]. The system will automatically cal-culate the correct offset value to use. If an ice bath is used, simply allow the temperature of the sensor to stabilize, and then enter 32 into the Current Value box and press [Submit]. This process should be repeated for each sensor in the system.

ESTABLISHING SETPOINTS

Cooling Setpoints

Access this screen from the Main Menu. Select Set-points, then Cooling, and finally Mode (1-4):


090.610-O (MAR 2016)Page 20

Zone Active / Off – This drop down menu must be set to Active for the zone to be able to run.

Mode Control – Set this based upon whether you would prefer Manual, Mode Schedule or Digital Input operation. Allows the user to manually set the active mode:

• Manual - Allows the zone to follow which-ever Mode (1-4) setpoints have been setup, based upon the Active Mode.

• Mode Schedule – The zone will follow the Mode Schedule.

Active Mode – If Mode Control is set to Manual, the user can set the active Evaporator mode.

A Defrost can be initiated at anytime be pressing the [Start Defrost] button.

THE HOME SCREEN

This screen will appear each time the Interface Panel has been powered up (default). It can also be accessed from the main menu by selecting Home.

Many of the operating characteristics for each zone can be viewed from here. The upper left hand corner of the screen tells you which zone is currently being viewed, and the zone setpoint box allows you to enter the number of any other enabled zone that you may wish to view.

The square grey box in the lower left hand corner will contain a red blinking dot if any zone being viewed has an active alarm condition, or a yellow blinking dot if any zone has an active warning..

This screen will display basic alarm information for the se-lected zone, as well as the current temperature and zone setpoint. At the bottom of this screen, basic status infor-mation is provided about valves and the fan. The Defrost box provides information when a defrost is underway.

The four Cooling Mode screens allow each zone to operate with four separate groups of setpoints. This screen shows the setpoints available for configura-tion based upon the selecting mode on the Current Zone Configuration page. Most importantly, the Liq-uid On and Off temperatures should be set, as well as the Fan On and Off temperatures. It is also recom-mended to set the Alarm High and Low temperatures for each Mode.

Defrost Setpoints

Access this screen from the Main Menu. Select Set-points, then Defrost, and finally Defrost Setpoints:

The Defrost Setpoints screen permits the user to specify the duration of each defrost step. Addition-ally, the Defrost Initiation should be set for each zone. During the configuration process, it is possible to start a defrost via the Mode Setup screen (see next section). The Next Stage button on the Defrost Set-points screen can then be used to advance through the defrost in order to validate valve operation.

THE MODE SCREEN

Access this screen from the Main Menu. Select Modes:

This screen is used to set each of the individual zones as to which Mode (1-4) they will perform. As described ear-lier, set the Zone number to the zone you which to setup.


090.610-O (MAR 2016)Page 21

ALARMS

Access this screen from the Main Menu. Select Safeties, and then Current:

This screen shows any alarms or shutdowns that are currently active for the zone selected. To view the ac-tive alarms/shutdowns for another zone, simply enter the number of the zone into the Zone setpoint box in the up-per right corner of the screen.

If an alarm is allowed to continue, a shutdown could re-sult. When a shutdown occurs in any zone, that zone will be prevented from running until the shutdown is corrected and cleared.

The alarms/shutdowns may be cleared for each zone by tabbing to the [Clear Safeties] button in the upper right corner, and press [Enter].

ZONE OVERVIEW SCREEN

Access this screen from the Main Menu. Select Zone Overview:

This screen permits the user to view the status of each Evaporator zone, as well as the current temperature. In the event that a zone has an active warning, the tempera-ture will be displayed in yellow, and if the temperature text is displayed in red, that zone is currently in shutdown. In either case, the operator should consult the Safeties screen to determine the nature of any alarms and resolve the problem.

AMMONIA CONFIGURATION

The first step in configuring and calibration the ammonia sensors, is to insure that all sensors are first plugged in. Channels 4, 5 and 6 of each Remote I/O Panel are pre-configured to accept three ammonia sensors on analog inputs.

NOTE: This manual has been written based upon Session Level 2 security. To assess the following screen, Session Level 3 must be set. Access the following screen from the Main Menu; Select Cali-bration, then Ammonia Sensors, and finally Page 1 (or 2):

Use the above screen to calibrate each ammonia input channel using an ammonia detector.

After calibrating all ammonia sensors, the alarm thresh-olds need to be set. Access the following screen from the Main Menu. Select Configuration, then Ammonia, and fi-nally Page 1 (or 2):

Use the above page to set the warning and shutdown ammonia levels for each ammonia sensor, as well as the associated delays. Each sensor may also be given an indi-vidual name from this page.


090.610-O (MAR 2016)Page 22

• System Ammonia Shutdown – If any configured zone within the system has an active Ammonia Shutdown, then the System Ammonia Shutdown output as set on this screen will be energized.

Additionally, you can configure the board and channel for the standard system warning and shutdown alarms.

• System Warning – If any configured zone within the system has any active Warning, then the System Warning output as set on this screen will be energized.

• System Shutdown - If any configured zone within the system has any active Shutdown, then the System Shutdown output as set on this screen will be energized.

These can be used to alert the user if ANY configured zone has an active warning or shutdown.

Only the zone which has the physical warning/shutdown out-put needs to be configured. Any warnings or shutdowns within the system will then cause that output to be energized. In the example shown above, zone 26 has an active warning. Zone 4 has been configured for Digital Board 2 as the Device Source and the I/O channel has been set to 19. This particular warn-ing from zone 26 will cause the horn on zone 4 (output 19) to sound.

In order for a zone to properly display and act upon alarms and shutdowns, the zone must have one or more am-monia sensors assigned to it. To access this screen, select Menu > Setpoints > Safety:

Finally, there are four system wide alarm inputs that can be configured. NOTE: This manual has been written based upon Session Level 2 security. To assess the fol-lowing screen, Session Level 3 must be set.

Up to four ammonia sensors may be mapped in the sys-tem to any zone. These assignments must be made to every zone.

To access this configuration screen, select Menu > Con-figuration > Digital I/O:

At the bottom of this screen there is an ammonia warning and shutdown alarm output which the board can be config-ured for. These will alert the user if any configured zone has an active ammonia warning or an active ammonia alarm. This can be any unused output. The Ammonia warning / shutdowns can be used for plant warnings that pertain to ammonia and not standard shutdowns or warnings.

• System Ammonia Warning – If any configured zone within the system has an active Ammonia Warning, then the System Ammonia Warning output as set on this screen will be energized.

TROUBLESHOOTING

The following section will help to identify some common prob-lems that may arise within an Evaporator system. Use this sec-tion in conjunction with the 090.610-M (Maintenance) manual.

Operator Interface Panel

1. Quantum™ controller does not have any LED’s lit:

• Check for the presence of 120 VAC power at the incoming AC terminal strip. (see the section entitled CHECKING THE AC POWER)

• Check for the presence of proper DC power to the Quantum™ (refer to the 090-610 M manual under the section entitled QUAN-TUM™ LX CONTROL PANEL POWER SUP-PLY.

• If the Quantum™ controller has proper DC voltage applied, then with turn the control power OFF, remove the program flash card, and recycle the power. If the LED’s do not start their booting pattern, continue to the next step.

• Try disconnecting all cables one at a time (with the exception of the DC power). If the LED’s start flashing normally, then recon-nect the removed cables one at a time, until the problem reappears, then troubleshoot that cable.

• If the DC power to the Quantum™ controller is normal, and the cables from the previous step had all been removed without correct-ing the problem, then the board will need replaced.

2. Quantum™ appears to boot normally, but nothing shows on the display:

• Ensure that the display cable is securely plugged in at both ends.

• For the Q4 controller only, Verify that jump-ers LK3 and LK4 are set properly. Both links should be set to position B.

• Ensure that the connectors on both ends of backlight inverter board are plugged in se-curely. Use caution when checking around the inverter, as high DC voltage is present when the control power is ON.

• Shine a flashlight onto the display screen at an angle. If the Quantum™ has properly booted, you should see some text dimly shown on the screen. If it appears as though there IS something being displayed, but it is not visible, then there is a problem with the backlight, the inverter, cable or Quantum™.

Remote Panels

1. LED’s are not lit on one or more I/O boards within the panel.

• Ensure that both HOA modules have their cir-cuit breakers engaged (see the section entitled CHECKING THE AC POWER).

• If both breakers are engaged, check the incom-ing 120 VAC power. (see the section entitled CHECKING THE AC POWER)

• If AC power is correct, and breakers are en-gaged, measure the DC voltage to the ques-tionable board(s) as described in the Digital or Analog board sections of the 090-610 M (Main-tenance) manual.

• If DC power to the questionable board(s) is good, replace the board.

2. One or more of the boards within a Remote Panel are not being detected on the About screen:

• Refer to the Evaporator System Communications Wiring Diagram and verify that the board DIP-SWITCH settings are correct.

• Verify that the communications wiring polarity is correct.

• Push the [Redetect] button on the About screen to see if the failing board is now redetected.

OVERVIEW OF OPERATOR INTERFACES

Web Browser

The web browser interface can be viewed from any desk-top or laptop computer, which has access to the network that an Evaporator Controller is attached to. To change screens, setpoints, etc., you simply use a mouse and the keyboard to view and change data.

All Evaporator screens that are shown will have several buttons on the right hand side of the screen. Most screens will have three buttons, and one setpoint box. The three buttons are:

[Menu] – Clicking on this button will cause the main menu to appear on the left side of the screen. Click-ing a second time will cause the menu to disappear.

[Start Refresh] [Stop Refresh] – This button(s) ap-pears immediately below the [Menu] button. This is actually a toggle button, as it changes function from Start Refresh to Stop Refresh each time it is clicked on. When the button shows as Start Refresh, a set-point box will appear below it, with a time value dis-played. The time value determines how often the display screen will refresh, or update its values. This time value is defaulted to 5 seconds, which means that the display will update all values shown every 5 seconds. Depending on the network connection speed, this updating may interfere with your ability to change data setpoints, because the screen will re-fresh while you are entering the data. To solve this, simply toggle the Refresh Button. By pressing [Stop Refresh], screen refreshing will terminate, and the time setpoint box will reappear. In this state, the par-ticular screen that you are viewing will never update the displayed values. Changing to another screen will show the most recent values on the new screen, and then will not update again. So in the Stop Refresh state, screens will only be updated when new screens are accessed. This feature should not be used when monitoring data.

One screen that DOES NOT have these buttons is:

Software Maintenance – To leave this screen, click on [Exit] button. Note: Using the [Exit] button takes several seconds, and it will force the password level back to zero.

OPERATOR ACCESS

Operator access to this system is through various screens. A screen is the physical representation of data on the dis-play. Each screen has a title area. The title is descriptive of the screen. The current date and time is shown in this title area. The day of the week, Sunday (Sun.) through Saturday (Sat.) is displayed. The month of the year from January (Jan.) to December (Dec.) is displayed. The day of the month from 1 to 31 and the year from 0001 to 9999 is displayed. The time displayed is the current time in 24 hours (military) format. The hours, minutes and seconds are displayed.

Some screens are for informational purposes only, and cannot be modified. These screens typically show analog values such as temperature and humidity, which are strictly functions of an associated sensor, and as such, cannot be modified. Other screens show setpoint values which can be changed, in order modify the units operating characteristics. For easier viewing, related information is separated into boxes. Sometimes selec-tions are hidden when that the feature is unavailable.

TO CHANGE SETPOINTS

The setpoints define the operation and limits of each air unit. These setpoints can be change by operators in the field. These setpoints are stored on the compact Flash card.

NOTE: Setpoints are not lost after power is interrupt-ed. However, we suggest that a list of Setpoints be recorded and stored safely to facilitate reentry, in case there is a need to return to the original settings.

1. The data entry fields are identified by a black box with a white interior. The data is shown in black text. When on a screen that has adjustable setpoints, tab to the setpoint box that you wish to modify (or select it on a web browser). Once the data field has been selected, the background turns blue, and the text turns white.

2. The current value of that setpoint is shown. Use the keypad to enter the new value. Typing a new value will completely erase the old value.

3. Press the keypad [ENTER] key to input the new data in the data entry field and to move to the next data entry field.

4. If the data entered into the setpoint box is valid, then once you have pressed the keyboard [EN-TER] key, the [SUBMIT] box in the lower left hand side of the viewing screen will turn from a grey background, to a red background. After all the setpoint changes on this screen have been entered, press the [SUBMIT] button to save the setpoint changes to memory.

5. If the value is out of bounds, an error message box displays the proper range of values. Press the [OK] button to acknowledge the error mes-sage. Re-enter a correct value.

USER DEFINED OPERATING STAUS SCREEN

DESCRIPTION: The purpose of this screen is to allow the user to select additional analog channels to be more readily view-able. Since the main Operating Status (Home) screen is ca-pable of only showing a limited number of pre-assigned analog values, it may be desirable for the user to have a method of viewing additional information that they can select, on a com-mon screen. They may even select values that are already be-ing displayed on the Operating Status screen, as well as values that are not shown there. This screen is provided to allow the user to view up to 20 dif-ferent analog channels of their choosing.

Notice at the top of this screen is a setpoint entry box, where a particular zone number can be entered. When a different zone number is entered and submitted, the screen data will be up-dated with the information from that zone. This same setpoint box appears on many of the screens.

As an example of how this screen works, assume that in addi-tion to the data that is shown on the Operating Status screen, the user would like to monitor the Return Air Temperature, Ammonia and Humidity, all on the same screen (this one).

Notice that Return Air Temperature and Humidity are already shown on the Operating Status (Home) screen, but the Ammo-nia is not shown. In order to set this screen up to show these three values, the user would highlight the Enable User Defined Channel 1 (or whatever channel they wish to use), by using the keypad to tab it. Once the box is highlighted, press the [Enter] key to show a drop down menu. Use the tab or arrow keys to scroll through the list. When the selection that you want to use has been highlighted, press the [Enter] key to select it. Once selected, a value will appear to the right of the list, which corre-sponds to the analog value for that channel. Press the [Submit] key to accept any changes.

The following selections may be shown on this screen:

• Control Temperature• Ammonia• Humidity• Auxiliary Analog 1 - 10

The date and time of the warning or shutdown occurrence is shown to the right of its description. The most recent message will appear on the top line of the screen with the oldest appearing at the bottom. When a Warn-ing or Shutdown is logged to this screen, it will also be logged to the Safety History screen.

The following Current Safeties screen key is provided:

[Clear Safeties] - Selecting this key will clear all warnings and/or shutdowns from this screen. This will also place a date/time stamp for the corresponding entry on the Safety History screen showing that the particular Warning or Shutdown was cleared. Clearing the entry on the Current Safeties screen, will not clear it from the Safety History screen.

To resume normal operation it will be necessary to go through the following steps:

1. Correct the condition(s) causing the warning.

2. Press the [ALARM SILENCE] key to turn off the warning device. (This action may precede correcting

the condition(s) causing the warning). Or, go to step 3.

3. To clear the Warnings/Shutdowns screen and turn off any warning device, press the [Clear Safeties] key.

4. If the conditions causing the warning have not been corrected or a new fault has occurred, a new WARN-ING or SHUTDOWN message will appear. The Safety History screen keeps a record of the warnings and shutdowns. This information will help troubleshoot persistent operational problems.

NOTE: There are two system-wide events that can occur, which provide an output signal that can be used as an alert. These events are:

• System Warning – If any configured zone within the system has any active Warning, then the System Warning output will be energized.

• System Shutdown - If any configured zone within the system has any active Shutdown, then the Sys-tem Shutdown output will be energized.

Refer to the Warnings/Shutdowns Message section for a list of possible conditions.


090.610-O (MAR 2016)Page 36

SAFETIES - Safety History

DESCRIPTION: The Safety History screen shows the warnings and shutdowns that have recently occurred. When a warning or shutdown is triggered, a blue descriptive message shows on this screen. The date and time of the warning or shutdown occurrence is shown to the right of its description, followed by the date and time that the safety was cleared. The most recent message will appear on the top line of the screen with the old-est appearing at the bottom.

It is possible to view the conditions that are shown on the Operating Status screen at the exact moment that a warn-ing/shutdown occurred. Use the tab key to select (highlight) a warning or shutdown and then press [Enter] to view its associ-ated Freeze (Operating Status) screen.

Freeze Screen Description

This Freeze screen provides a snapshot of the values that were current at the time of the latest warning/shutdown. The information on the Freeze screen can help the user to identify the cause of the fault. The Freeze screen has the same appearance and contains the same informa-tion as the Operating Status screen. (For a description of the information presented by the Freeze screen, refer to the Operating Status screen). This data is saved during a power outage.

DESCRIPTION: This is the Trending Setup screen. Up to eight channels can be monitored in real time trending, and up to eight channels monitored in history trending.

Real Time Trending - is a method by which the user can set the Quantum™ LX to map analog inputs to a graphic chart for-mat. These analog input values are stored at a specific interval over a corresponding period of time. The graphed values will scroll across the screen from left to right, at a speed that is de-termined by the recording interval. Two individual data points can be viewed on the Real Time Data Log screen. A total of 900 values are stored. Trending data is lost upon power cycle.

The following setpoints are provided:

Real Time Recording Interval – The time interval that defines how often the real time trending data values are updated. This value may be set for any time duration be-tween 1.0 second and 86,400.0 seconds (24 hours).

History Trending - is a method by which the user can set the Quantum™ LX to record analog inputs to a graphic chart format. This feature is similar to Real Time trending, except that the data is not lost at power cycle. The events that occur will scroll across the screen, at a speed that is determined by the recording interval. A total of 2000 values are stored.

History Recording Interval – The time interval that de-fines how often the history trending data values are up-dated. This value may be set for any time duration be-tween 1.0 minute and 60.0 minutes (1 hour).

SETPOINTS – Cooling (Mode 1)

DESCRIPTION: This screen allows for the setup of the Mode 1 Cooling. In addition to this screen, there is also Mode 2, 3 and 4 Cooling Modes. Cooling Control Setpoints are used to maintain temperature. When a zone is cooling, the control temperature determines whether the liquid valve is open or closed, based upon the Liq-uid On and Liquid Off setpoints. Suction operations are based on the configuration specified on the Current Zone Configura-tion screen. If Suction has been set to Always, then the Suction valve will remain open at all times, otherwise the Suction will only open when the Liquid valve is open.

This screen provides setpoint boxes to allow for the configura-tion of Cooling Mode 1:

Liquid

Digital Control

• On - If the control temperature equals or exceeds this setpoint, the output for the liquid valve will be energized or turned on to open a liquid valve and therefore provide cooling.

• Off - If the control temperature is less than or equal to this setpoint, the output for the liquid valve will be de-energized or turned off to close a liquid valve and therefore pre-vent further cooling.

Analog Control

• Setpoint – The value that the unit will at-tempt to maintain temperature to.

• Proportional Band – The temperature range over which the PID control will be managing liquid cooling (provided Integration Time is not set to zero, in which case it will be strict-

ly proportional). If the Setpoint is 40 degrees and the Proportional Band is 2 degrees, the PI control will set the output to Liquid Min if the temperature is below 40 degrees (Set-point). When the temperature is between 40 and 42 degrees (Setpoint plus Proportional Band) the PI control will be increasing the output in a manner to bring the liquid tem-perature toward the setpoint). Above 42 de-grees the output will be set to Liquid Max.

• Integration Time – The Integral component works to push the Control Input toward the Control Setpoint by tracking the difference between the Control Input and the Control Setpoint over time.

• Maximum – This is the maximum percent of the analog output signal.

• Minimum – This is the minimum percent of the analog output signal.

Dehumidification

• On – If the humidity level falls below this value, the dehumidification control will operate.

• Off – If the humidity level exceeds this value, then dehumidification will terminate.

• Low Temperature – When the control tem-perature falls below the Low Temperature setpoint, dehumidification will terminate to prevent driving the temperature lower.

Reheat

• On – If Reheat has been enabled, and the tem-perature falls below this value, then the Reheat valve will be opened.


090.610-O (MAR 2016)Page 43

• Off - If Reheat has been enabled, and the tem-perature rises above this value, then the Reheat valve will be closed.

Fan

Digital Control

• On - If the control temperature reading equals or exceeds this setpoint, the fan out-put will be energized or turned on to run the fan.

• Off - If the control temperature is less than or equal to this setpoint, the fan high-speed output will be de-energized or turned off to stop the fan.

Analog Control


• Proportional Band – The temperature range over which the PID control will be managing fan operation (provided Integra-tion Time is not set to zero, in which case it will be strictly proportional). If the Setpoint

is 40 degrees and the Proportional Band is 2 degrees, the PI control will set the output to Fan Min if the temperature is below 40 degrees (Setpoint). When the temperature is between 40 and 42 degrees (Setpoint plus Proportional Band) the PI control will be increasing the output in a manner to bring the liquid temperature toward the setpoint). Above 42 degrees the output will be set to Fan Max.

• Integration Time – This setpoint controls the influence that the Integral component exerts on the PID Output value. The Integral component works to push the Control Input toward the Control Setpoint by tracking the difference between the Control Input and the Control Setpoint over time.

• Maximum – This is the maximum percent of the analog output signal.

• Minimum – This is the minimum percent of the analog output signal.


090.610-O (MAR 2016)Page 44

SETPOINTS – Heating (Mode 1)

DESCRIPTION: This screen allows for the setup of the Mode 1 Heating. There is also Mode 2, 3 and 4 Heating Modes. Heating (using hot gas as the heat source) is sometimes used to raise the temperature within an area of a plant such as a loading dock. The process of heating initiates with the Pre-heat stage. Pre-heat is used to properly prepare for heating. Pre-heat can consist of three steps: Pump Out, Soft Hot Gas, and Fan Delay. Then Hot Gas heating operates by opening the Hot Gas valve when the temperature falls below the On setpoint, and turns the valve off when the temperature exceeds the Off setpoint. This process continues until it becomes necessary to terminate heating. Post-heat stage is used to properly exit from heating. Post-heat can consist of two steps: Bleed, and Fan Delay. Each step has an operator adjustable time setpoint.

This screen provides setpoint boxes to allow for the configura-tion of Heating Mode 1:

Hot Gas

• On - If the control temperature is less than this setpoint, the output for the Hot Gas solenoid valve will be energized to provide heating.

• Off - If the control temperature equals or ex-ceeds this setpoint, the output for the Hot Gas solenoid valve will be de-energized to cancel heating.

Fan

Digital Control

• On - If the control temperature is less than this setpoint, the output for the Fan will be energized.

• Off - If the control temperature equals or exceeds this setpoint, the output for the Fan will be de-energized

Analog Control


• Proportional Band – The temperature range over which the PID control will be managing fan operation (provided Integra-tion Time is not set to zero, in which case it will be strictly proportional). If the Setpoint is 25 degrees and the Proportional Band is 2 degrees, the PI control will set the output to Fan Min if the temperature is below 23 degrees (Setpoint minus Proportional Band). When the temperature is between 23 and 25 degrees, the PI control will be decreas-ing the output towards the Fan Min value. When the temperature is between 25 and 27 degrees (Setpoint plus Proportional Band) the PI control will be increasing the output in a manner to bring the liquid temperature toward the setpoint). Above 32 degrees the output will be set to Fan Max.

• Integration Time – This setpoint controls the influence that the Integral component exerts on the PID Output value. The Integral component works to push the Control Input toward the Control Setpoint by tracking the difference between the Control Input and the Control Setpoint over time.

• Maximum – The maximum speed for the variable speed fan output.


090.610-O (MAR 2016)Page 45

• Minimum – The minimum speed for the variable speed fan output.

• Cycling – When enabled, the fans will con-tinue to switch on periodically when the heating requirement is satisfied.

Transition – When a mode has both heating and cool-ing enabled, it is important to specify the transition tem-perature to limit delays associated with the Pre-heat and Post-heat stages. This allows for the Pre-heat stages to start before the temperature falls below the Hot Gas On

setpoint. Similarly, as the temperature is rising toward the Cooling On setpoint, the Post-heat stages can begin be-fore cooling is required.

• Cooling To Heating – When the temperature falls below this value, Pre-heat stages will be executed.

• Heating To Cooling – When the temperature exceeds this value, the Post-heat stages will be executed.


090.610-O (MAR 2016)Page 46

SETPOINTS – Heating Timers

DESCRIPTION: This screen allows for the setup of the Heating Timers, as they apply to Heating Modes 1, 2, 3 and 4.

Pre-Heat:

• Pump Out - The time in minutes to pump out the liquid in the coils. During this step, the liquid and hot gas valves are closed, the suction valve is opened, and the fans are running. The fan runs according to the fan settings that were entered on the “Heating Setpoints” screen. If it is a two-speed fan, the selected fan speed is energized. If it is a variable speed fan, the fan is turned on the amount of the variable percent.

• Pump Out Fan Speed – The speed setting of the

fan while it is running during pump out.

• Soft Hot Gas - The time in minutes to provide soft hot gas heating of the coils. During this step, the soft hot gas valve is opened, the other valves are closed, and the fans are stopped. - (enhanced unit only).

• Fan Delay - The time in minutes to provide hot gas heating of the coils without fans running.

During this step the hot gas valves are opened, the other valves are closed, and the fans are stopped.

Post-Heat:

• Bleed - The time in minutes to bleed (bleed valve is opened). During this step, all other valves are closed, and the fans are not running.

• Fan Delay - The time in minutes to delay after

heating, prior to starting the fans and the cool-ing process. This is the last step of the sequence. This step is important for preventing liquid from being blown off the evaporator coils and into the room. Opening the liquid valve will start frosting the evaporator coils. During this step the liquid and suction valves are opened. The soft hot gas, hot gas, and bleed valves are closed, and the fans are not running.


090.610-O (MAR 2016)Page 47

SETPOINTS – Mode Schedule

DESCRIPTION: Scheduling allows the user to program up to four different operating schedules for each day of the week. This can be a great way to save energy. At night or on week-ends and holidays, or even over lunch periods, a higher tem-perature can be set to reduce energy consumption. This screen shows a time schedule. Up to four different modes can be entered for each day of the week. The Schedule is only effective if the Mode Control selection is set to automatic.

Notice that there are four columns of Hour/Minute entries, each followed by an Operating mode selection. The available selections are:

• Off• Mode 1• Mode 2• Mode 3• Mode 4

Use the left most column (on the row for the day of the week that you wish to schedule) to enter the time of day that you would like the Evaporator to switch from it’s previous operat-

ing mode, into a new mode. When that time of day arrives, the Evaporator Unit will be switched over to the scheduled mode. This mode will then be the active running mode, and will con-tinue to be the active mode until the time in the succeeding column is reached. If the time in the next column is 00:00, it will be skipped.

The Schedule must be activated to switch the presently active mode to the Scheduling mode at the assigned time. An entry of 00:00 will void the time entry field. If a mode change is required at midnight (00:00) use 00:01.

The following are descriptions of the setpoints:

Time Column - The time of day that you want to switch to the Scheduled Mode of control.

Mode Column - Set this to the Mode that you want to run at the assigned time.


090.610-O (MAR 2016)Page 48

SETPOINTS – Defrost Setpoints

Defrost is used to remove the build up of ice that reduces cooling efficiency. The defrosting of a zone can consist of five steps: Pump out, Soft Hot Gas, Hot Gas, Bleed, and Fan Delay. Each step has an operator adjustable time setpoint.

The following setpoint boxes appear on this screen:

Defrost Timers

[Pump Out] - The liquid output is closed (de-ener-gized) while the suction valve and the fan output re-main opened (energized) to remove and evaporate as much as possible of the remaining liquid refrigerant.

[Soft Hot Gas] – (Enhanced unit only) The soft hot gas valve is opened, the other valves are closed, and the fans are stopped. The soft hot gas valve is used to slowly turn on hot gas and lower the pressure dif-ferential that occurs when going from cooling to de-frosting.

[Hot Gas] – The hot gas valve is opened, the other valves are closed, and the fans are stopped. The hot gas solenoid is energized for the set amount of time. This step allows high pressure/high temperature gas to enter the evaporator coil and melt the frost build up on the evaporator coils clearing the coil for good airflow.

[Bleed] – The hot gas solenoid output is de-ener-gized, and the bleed solenoid output is energized for the set amount of time. This bleed step is usu-ally energized for a few minutes to allow the hot gas trapped in the evaporator coil to slowly release from the tubing. This prevents quick over pressurization of the suction piping line and vessel.

[Fan Delay] - The bleed solenoid is de-energized and the liquid and suction solenoid outputs are energized again allowing the liquid refrigerant to cycle through the evaporator coil thus cooling the evaporator to an operating temperature. This step usually lasts for just a few minutes and is used mainly to frost the small amount of water left on the unit so as to not blow water over product when the fan is restarted. After Fan Delay, the fan output is energized again to pro-vide air movement across the evaporator coil to re-initiate the cooling process.

[Liquid Timer Setpoint]

[Maximum Hours Between Defrosts] – Enter the maximum number of hours that you want between defrosts.

[Defrost Initiation] – The following drop down box is provided:

• None

• Defrost Schedule – Defrosts are initiated at the times specified in the Defrost Schedule.

• Liquid Timer – Defrosts are initiated when the Liquid Timer exceeds the Liquid Timer setpoint.

• Defrost Schedule with Liquid override – De-frosts are initiated according to the Defrost Schedule, provided that the Liquid Timer has exceeded the Liquid Timer setpoint.


090.610-O (MAR 2016)Page 49

[Demand Defrost] – The following drop down box is provided:

• Disabled – The Defrost Input is not moni-tored.

• Enabled – The Defrost Input will be moni-tored, and a zone defrost will be initiated when this input is energized.

The following screen buttons have also been provided:

[Clear Liquid Timer] – This button will set the Liquid Timer to zero.

SETPOINTS – Defrost Schedule

Each pair of text boxes allow the user to enter a time in hours (0-23) and minutes (0-59). A defrost will be initiated for each entry on the defrost schedule, provided that the Defrost Source is set to initiate defrosts by the Defrost Schedule.

An entry of 00:00 will void the time entry field. If defrost is required at midnight (00:00) use 00:01.

If liquid override is enabled, these times are also dependent on a Liquid counter setpoint. The liquid counter counts a cumula-tive time that the liquid solenoid output is open between de-

frosts. When the panel reaches a time in the Defrost Schedule and the liquid counter exceeds the Liquid counter setpoint, then the unit goes into it’s defrost mode. If the counter has not exceeded the Liquid counter setpoint, no defrost is initialized.

The following are descriptions of the setpoints:

Time Column - The time of day, in hours and minutes, that you want to switch to defrost a particular zone.


090.610-O (MAR 2016)Page 50

SETPOINTS – Safety Setpoints

The top right corner of this screen shows the zone number which is currently being viewed. Any changes to this screen will be applied to this zone. Change the Zone setpoint box to view other zones.

The following Pull down menus and setpoint boxes appear on this screen, for the zone selected:

Ammonia Sensors – Up to four ammonia sensors may be monitored by each zone using the four pull-down menus shown. The assigned sensor does not need to be physi-cally tied to the zone selected, it can be any sensor within the entire system. The same sensor may even be used for multiple zones.

If the ammonia PPM value at any of the selected sensors ex-ceed the safety Warning or Shutdown setpoint for the zone (located on the Configuration – Ammonia Sensor Configura-tion screen), then the panel will show the Warning/Shutdown message.

Powerup Delay – Upon powerup, the control system will remain inactive for this period of time.

Fan Auxiliary - This is an auxiliary input signal from a fan starter that confirms when the fan is running.

• Disabled – The Fan Auxiliary Input is not in use.

• Enabled – The Fan Auxiliary Input will be moni-tored whenever the Fan Output is energized. In the event that the Fan Auxiliary Input becomes de-energized, a zone shutdown will occur.

• Delay – When Fan Auxiliary is enabled, this De-lay specifies the period of time that will elapse before a zone shutdown occurs in the event that the Fan Auxiliary Input is de-energized while the Fan Output remains energized.

[Device Source] – The Evaporator Quantum™ LX can have up to ten analog boards. The first five boards service zones 1-15, and the second group services zones 16-30. A drop down menu is provided to select from the following analog boards:

• None• Analog Board 1 Port 4• Analog Board 2 Port 4• Analog Board 3 Port 4• Analog Board 4 Port 4• Analog Board 5 Port 4• Analog Board 1 Port 3• Analog Board 2 Port 3• Analog Board 3 Port 3• Analog Board 4 Port 3• Analog Board 5 Port 3

[Device Channel] - A setpoint entry box is provided to se-lect the analog board output channel that you wish to use.

[Output] - The value of the Output signal as controlled by the PID. This is not a setpoint value.

[Actual] - The Actual value of the input signal. This is not a setpoint value.

[Setpoint] - Enter the value that you wish to control to.

[Proportional Band] – This setpoint determines the size of a region either above or below the Control Setpoint. Within this region, the output is governed by the PID control, and assumes a value between high limit and low limit. Outside of this region, the Proportional component is either 100% or 0%. If the PID’s Action is Forward, the Proportional Band extends above the Control Setpoint. If the PID’s Action is Reverse, the Proportional Band extends below the Control Setpoint.

[Integration Time] - This setpoint controls the influence that the Integral component exerts on the PID Output value. The Integral component works to push the Control Input toward the Control Setpoint by tracking the differ-ence between the Control Input and the Control Setpoint over time.


090.610-O (MAR 2016)Page 52

[High Limit] - The highest value that the output can be.

[Low Limit] - The lowest value that the output can be.

[When Running Off Value] - If the PID’s Control is When Running, this value sets the value of the PID output when the Evaporator is off.

Overview to Tuning a PID Controller

The purpose of this section is to give some basic guide-lines for tuning Proportional Band and Integration Time of a PID controller. To tune a PID controller, it would be advantageous to hook the system up to some test equip-ment to allow you to record the appropriate variables. At the very least, the appropriate data will have to be moni-tored and recorded by hand from the system screen for subsequent evaluation and possible spreadsheet graphing.

Proportional Band - When the control Input is at the Control Setpoint, the Proportional component of the PID Output will be 0%. As the Control Input moves through the Proportional Band, and away from the Control Setpoint, the Proportional component will increase. If the Control Input is in the middle of the Proportional Band, the Pro-portional component value is 50%, and when the Control Input reaches the outside of the Proportional Band, the Proportional value will be 100%. The value of the Propor-tional component is calculated as the difference between the Control Input and the Control Setpoint, divided by the Proportional Band and then multiplied by 100.

Example:

Control Input: Return Air Temp.Control Setpoint: 100° FProportional Band: 10° FAction: Forward

Control Input Proportional Output

100° F 0%

102.5° F 25%

105° F 50%

108° F 80%

110° F 100%

112° F 100% The value selected for the Proportional Band will be de-termined by the stability of the system, the accuracy re-quired, and the average output value, among other things. One way to pick a starting value is to find a range of al-lowable Control Input values and then to select a Propor-tional Band so that the Proportional value will reach 100% before the Control Input moves outside of the allowable range.

After the initial value is entered for the Proportional Band, watch the system to see how it reacts. If the PID output shows too much oscillation, increasing the Proportional Band will cause the control to react slower, which will dampen this oscillation. If the PID reacts too slowly, then decreasing the Proportional Band will make the control react faster.

Proportional Only Control - There will be certain appli-cations in which only proportional control is required for good performance. When this is the case, the Integration Time can simply be set to zero, and the Proportional Band set to a desired value.

Some advantages of only using Proportional control are that it is generally more stable than Proportional and In-tegral control and its function is easier to understand. A disadvantage of only using Proportional control is that the Control Input usually will settle into a spot somewhere in the Proportional Band, and will not move to the Control Setpoint. For instance, from the example shown above, if the Proportional Output averages 80%, then the Control Input will remain at 108° F and will not go to 100° F. This may be acceptable in some applications. In certain other cases the setpoint can be offset to move the Control Input to the point it needs to be.

Integration Time - The Integral calculation in PID control uses past performance to calculate a value for the PID output. It does this by periodically adding a small value to the PID output to move the Control Input toward the Control Setpoint. Eventually, the Integral component of the PID output will equal the average PID output value as Control Input gets to the Control Setpoint, and the Pro-portional component goes to 0%. When combined with the Integral calculation, the Proportional component can be negative and its range becomes -100% to +100%. If the Control Input moves above or below the Control Set-point, the Proportional control will prevent it from moving too far, and the Integral control will move it back to the setpoint.

Once the Proportional Gain is set, start with a large Inte-gration Time (180 seconds). Here again, you want to find the range of Integration Time that gives you reasonably fast performance, without too much overshoot, and with-out too much oscillation. If the Control Input repeatedly overshoots the Control Setpoint, or oscillates too much, increasing the Integration Time will slow the control. If the Control Input moves too slowly toward the Control Setpoint, decreasing the Integration Time will cause the control to react faster.

SETPOINTS – Auxiliaries – Digital Input Configuration

Use this screen to setup an Auxiliary Digital Input that is to be used to generate a warning or a shutdown whenever the associated input is not energized (off). As an example from the screen shown above:

If Auxiliary Input 1 is set to Shutdown When Running, and the Delay is set to 10 seconds, then whenever the device that is physically attached to I/O Channel 15 (Digital Board 1) becomes de-energized (turns off) AND the unit is Running, then the de-lay timer will start to count down. When the Delay times out, a shutdown message is issued (Auxiliary Input 1 Shutdown), and the unit will stop running.

As an example of how this screen could be used would be if you had an emergency stop switch. As long as the input remains energized, the unit will continue to run. However, if the emergency stop switch is configured to open the circuit, it would thereby de-energize the input on board 1, channel 22. The zone would shutdown, and cease operation.

A drop down menu box is provided for each of the eight pos-sible Auxiliary Inputs:

[Activity]

• Disabled - The device will not be monitored for warnings or shutdowns.

• Shutdown When Running - The device will be monitored for shutdown occurrences only when the zone is on.

• Shutdown Always - The device will be monitored for shutdown occurrences all of the time.

• Warning When Running - The device will be monitored for warning occurrences only when the zone is on.

• Warning Always - The device will be monitored for warning occurrences all of the time.

[Delay] - This value specifies the duration that the digital signal must remain off before an alarm is issued.

CALIBRATION – Analog Inputs

DESCRIPTION: This screen is used to calibrate the Return Air Temperature, Ammonia and Humidity sensors. This screen should be used anytime a sensor is found to be out of calibration. The recommended practice for adjusting the calibration reading is to first determine which sensor(s) need to be calibrated. Once this is determined, you must know the actual reading that the sensor should be showing. This can be accomplished by comparing the displayed reading shown here, with the actual value using a separate measurement device, such as a Digital Volt Meter, or temperature probe, etc. As an example, assume that the Humidity on this screen reads 30%, but a separate device is showing a reading of 40%. Highlight the setpoint box for Humidity, and enter the value of 30. The new reading will now read 30, and should match your separate reading.

A setpoint box exists for each of the displayed analog readings:

[Return Air Temperature]

• Current Value• Offset

[Ammonia]

• Current Value• Offset• Low Range• High Range

[Humidity]

• Current Value• Offset• Low Range• High Range


090.610-O (MAR 2016)Page 60

CALIBRATION – Ammonia Sensors

DESCRIPTION: This screen is used to calibrate any installed Ammonia sensors.

NOTE: Each Ammonia sensor that is to be used must be calibrated before the system is put into operation. Page 1 allows for calibration of Ammonia Sensors 1 through 15, Page 2 allows calibration of Ammonia Sensors 16 through 30.

The displayed value of each installed ammonia sensor should be compared against the reading of a calibrated ammonia de-tector, and any compensation should be made to the sensor on this screen.

The following Setpoint boxes appear here:

Current Value – This box shows the actual value that the sensor is detecting.

Offset – This box is used to adjust (compensate) the value shown in the Current Value box. If the Current Value were displaying 100, but an ammonia detector were showing 95, the difference of 5 should be entered here.

Range

Low - Set the Low Range value according to the low range of the sensor itself.

High- Set the High Range value according to the high range of the sensor itself.

A Sensor Signal type is shown at the end of each row. This is informational only, and cannot be changed here.


090.610-O (MAR 2016)Page 61

CALIBRATION – Analog Output Calibration

DESCRIPTION: This screen is used to calibrate individual ana-log outputs.

Use this screen if an analog output signal (channel) requires calibration.

The QuantumTM LX analog outputs have a range of approxi-mately 0 to 25mA, but most devices that are controlled require a signal that varies between 4 and 20mA. To restrict the ana-log outputs to the proper values, each of the outputs must be calibrated before they can be used. Every output channel has a Top End and a Bottom End value that are used for calibration. Both values can be set from 0% to 100%. The output channel’s maximum value is represented by 100% and its minimum value is represented by 0%. To calibrate the channel, the Top End per-centage is decreased until the maximum output for the channel is limited to 20mA. In addition, the Bottom End percentage is increased until the minimum output for the channel is 4mA.

Below is a systematic procedure for calibrating one analog output.

1. Configure the analog output channel for its intended use. For example, if the channel is to be used for PID control, enter the Device Source and Device Channel of the selected analog output channel under one of the PID columns on the PID Setup page.

2. Set a meter to read the channel output value in mil-liamps.

3. Go to the Analog Output Calibration page.

4. Select the Analog Board and the Channel Number for the output that is being calibrated.

5. After the Analog Board and Channel Number are se-lected, the channel function will be displayed below the Channel Number. If Not Configured is shown here

instead, the channel has not yet been assigned a con-trol function. Return to step 1 and setup the channel for the control task it is to perform.

6. Press [1] and the value shown on the meter should go to the channel low-end value.

7. Check that the “Delta For Changing Output Percent-age” value is 10.00. If it is not, press [0] until it is displayed as 10.00.

8. If the channel output is greater than 4mA press [4]. If the channel output is less than 4mA, press [7]. Use these keys to find the output value closest to 4mA.

9. Press [0] once to decrease the “Delta For Changing Output Percentage” value to 1.00.

10. Use the [7] and [4] buttons again to find the value closest to 4mA.

11. Repeat steps 9 and 10 for Delta values of 0.1 and 0.01 to bring the output value as close as possible to 4mA.

12. Press [3] and the value shown on the meter should go to the channel high-end value.

13. Check that the “Delta For Changing Output Percent-age” value is 10.00. If it is not, press [0] until it is displayed as 10.00.

14. If the channel output is greater than 20mA press [4]. If the channel output is less than 20mA, press [7]. Use these keys to find the output value closest to 20mA.

15. Press [0] once to decrease the “Delta For Changing Output Percentage” value to 1.00.


090.610-O (MAR 2016)Page 62

16. Use the [7] and [4] buttons to again find the value closest to 20mA.

17. Repeat steps 15 and 16 for Delta values of 0.1 and 0.01 to bring the output value as close as possible to 20mA.

NOTE: The analog output channel will return to its control task either when another output channel is selected for calibration or when the user goes to another screen.

CONFIGURATION – Communications

DESCRIPTION: This screen is used to set the Panel ID number that this control panel communicates with, and the parameters for each of the two communications channels, as well as to show the status of the internal I/O board status. The following setpoints are provided:

[Panel ID] - The value of the Evaporator Quantum™ LX Control Panel that this Evaporator Controller is communi-cating with. On networked systems, this number must be unique. Valid values are from 0 - 99.

Comm1

(Setup parameter definitions for Comm1 and 2 are identical) Communications related information for the communications ports:

Status - Shows the current communications status of the port. The possible messages are:

• Off - No communications are currently taking place. NOTE: A delay of 15 seconds or more of inactive communications (time between valid re-sponses) will cause this message to display.

• Active - Valid communications are actively oc-

curring.

• Failed - An invalid command was received by the port. This could be due to a bad checksum value, a wiring issue, or hardware problem at either the transmitting or receiving (Quantum™ LX) end.

[Baud Rate] - The baud rate defines the speed at which external communications can occur. The higher the baud rate, the faster the communications. A drop down menu is provided to select from the following:

• 1200• 2400• 4800• 9600• 19200• 38400• 57600• 115200

[Data Bits] - Determines the number of bits in a transmit-ted data package. A pull down menu is provided to select from the following:

• 7• 8

[Stop Bits] - A bit(s) which signals the end of a transmis-sion on a serial line. A drop down menu is provided to select from the following:

• 1• 2

[Parity] - In communications, parity checking refers to the use of parity bits to check that data has been transmit-ted accurately. The parity bit is added to every data unit (typically seven or eight data bits) that are transmitted. The parity bit for each unit is set so that all bytes have either an odd number or an even number of set bits. Par-ity checking is the most basic form of error detection in communications. A drop down menu is provided to select from the following:

• None• Even• Odd


090.610-O (MAR 2016)Page 70

[RS-485 Communications] - (Available for Comms1 and Comms 2 only). This pull down box allows the user to se-lect whether or not the communications will be through RS-485 hardware protocol or not. A drop down menu is provided to select from the following:

• Yes• No

[Protocol] - A protocol is the special set of rules that each end of a communications connection use when they com-municate. A drop down menu is provided to select from the following Frick recognized protocols:

[I/O Comms] - A status indicator is provided to show the current state of the internal communications of the I/O boards. The possible displayed states are:

• Off - Loss of communications or intermittent communications failures to the internal Quan-tum™ LX I/O boards.

• Active - Indicates that normal I/O communica-tions are occurring.

• Failed - Loss of communications, a shutdown

message will be generated.

[Redetect IO Comms] - Select this key to detect all con-nected Analog and Digital boards. If a board has been re-moved, a communication error shutdown will be issued until this key is selected. Reference the About screen to view what has been detected.

[Use Map File] - Because the addressing scheme between earlier Quantum™ version software and the Quantum™ LX version 3.0x and later software is not the same, this utility was created. The map file is a conversion utility that can be used to allow a communications application that was previously written by the user under the Quantum™ version 2.3x and earlier to function properly with the LX by redirecting the old addresses to the new LX addresses. A pull down menu is provided to select from the following:

• No - Do not use map file, the user is either not going to be using external communications, or they will be writing the communication applica-tion based upon the LX addresses.

• Yes - The user has an application that was previ-ously written for the Quantum™ version 2.3x or earlier, and they want to utilize the same code for the LX.

Two keys are located at the bottom right hand side of the screen. The following describes their function:

[Download MapFile.txt from Quantum™ LX] – With a USB memory stick installed on the LX, pressing this key will cause the MapFile.txt file to be downloaded from the Quantum™ LX into the USB memory.

[Upload MapFile.txt to Quantum™ LX] – After the user has modified the MapFile.txt file to suit their needs, pressing this key will cause the file to be up-loaded from the USB memory back into the Quan-tum™ LX.

CONFIGURATION – Ethernet

DESCRIPTION: This screen is used to view and set basic Eth-ernet operational values. It is from this screen that all internet and e-mail based operating characteristics are set. NOTE: In order to connect to the Internet, a valid Internet account and connection must be used.

NOTE: User Level 1 or above must be set to access this screen.

The following fields are provided:

IP Data:

[Address Type] - The following drop down menu is provided:

• Fixed (Static)• DHCP (Dynamic)

This should be set by the network or LAN administra-tor.

[IP Address] - Four setpoint boxes are provided here. The network or LAN administrator will enter the nu-merical IP address for this specific Quantum™ LX panel.

[Gateway Address] - Four setpoint boxes are pro-vided here. The network or LAN administrator will enter the numerical Gateway address.

[Subnet Mask] – Like IP addresses, a subnet mask contains four bytes (32 bits) and is often written us-ing the same "dotted-decimal" notation. A subnet mask neither works like an IP address, nor does it ex-ist independently from them. Instead, subnet masks accompany an IP address and the two values work together.

Applying the subnet mask to an IP address splits the address into two parts, an "extended network ad-dress" and a host address.

For a subnet mask to be valid, its leftmost bits must be set to '1'. Conversely, the rightmost bits in a valid subnet mask must be set to '0', not '1'.

All valid subnet masks contain two parts: the left side with all mask bits set to '1' (the extended network portion) and the right side with all bits set to '0' (the host portion).

[Web Server Port] - One setpoint box is provided here. The network or LAN administrator will enter the numerical address for this Web port (80 is typically used).

Email Data

[Email Notification On Alarm or Shutdown] - For the E-mail notification feature to work, it must be en-abled (it is disabled as a default). The following drop down menu is provided:


[Local Email Address] - Use this setpoint box to enter a valid E-mail address that messages are sent from.

CONFIGURATION – Security

DESCRIPTION: This screen allows the user/supervisor to set the various levels of password protection. The Security screen shown above can only be modified at the Quantum™ LX con-trol panel via the keypad.

The various levels are:

• Level 0 - Also known as the BASIC level. This level is not shown on the Security screen, as it is the lowest level of system access, and as such, does not require a password to activate. This is the default level, and provides access to only the very basics of machine operation.

• Level 1 - Also known as the ADVANCED level. This requires a password to set. Only those users who are authorized with the password may enter this level. It provides greater access than Level 0 (BASIC). The valid entry range is zero (0) to 5000. The factory default value for this password is 10 (ten).

• Level 2 - Also known as the SERVICE level. This requires a password to set. Only those users who are authorized with the password may enter this level. It provides greater access than Level 1. The factory default value for this password is 20 (twenty).

To set the password protection for the each level, use the keypad to highlight the box beside the level that you wish to change. Set the level to either zero (0) or one (1), and enter the appropriate password for that level in the next box. The valid range for password entry is -999999 to 999999.

NOTE: It is highly recommended that the supervisor docu-ments this password and stores it in a safe place. If the password is ever forgotten, it can only be corrected by call-ing the factory.

SERVICE – Software Maintenance

DESCRIPTION: This screen allows the technician to perform system software maintenance. The following selections have been provided:

1) Save Setpoints - Use this option to save all setpoints and custom text to a USB device as a form of backup:

• Ensure that all setpoint values have been docu-mented as a safety precaution. Install a USB de-vice into the provide connection on the Quan-tum™.

• Press the [1] button

• The software program will read the USB device, and the following dialog box will appear:

• Any numerals that appear on the center line of this box, will represent units that have already been saved (from 0 to 99). If no units have yet been saved, the center line will be blank.

• Enter a number on the keypad that corresponds to the unit number that you wish to save, then press [Enter]. If the unit number has not been saved before, the setpoints will be saved to a file

on the USB device (a progress bar will appear asking you to Please Wait… In the future, any time you try to write the setpoints to this num-ber, you will be prompted with a message telling you that the set number already exists – do you wish to overwrite it? Answer by highlighting the Yes button, and pressing [Enter] if you do indeed wish to overwrite the values. If you enter a num-ber that does not appear on the center line, no such warning will appear.

• After the file has been written or updated, the dialog boxes will disappear, and you can either exit, or continue with another function.

2) Full System Install - Use this option to install the program:

• Ensure that all setpoint values have been docu-mented as a safety precaution.

• Press the [2] button.

• If a valid USB device with the operating system loaded on it is plugged in, the software will be loaded. If however, there is no USB device in-stalled, or the device does not contain the op-erating software, the following dialog box will appear:


090.610-O (MAR 2016)Page 79

• If the above dialog box appears, you must insert

a valid software upgrade USB device.

3) Restore Setpoints – Use this option to re-load previ-ously saved setpoints and custom text to the Quantum™.

• Ensure that all setpoint values have been docu-mented as a safety precaution. Install the previ-ously saved setpoint USB device into the pro-vided connection on the Quantum™.



• Any numerals that appear on the center line of this box, will represent units that have already been saved (from 0 to 99). If no units have yet been saved, the center line will be blank and therefore there are no setpoints to restore.

• Enter a number on the keypad that corresponds to the unit number that you wish to restore, then press [Enter].

• A progress bar will appear asking you to Please Wait…

• After the file has been written or updated, the dialog boxes will disappear, and you can either exit, or continue with another function.

4) Delete Setpoints – Use this option to delete the set-points and custom text for a particular unit.:

• Ensure that all setpoint values have been docu-mented as a safety precaution. Install the previ-ously saved setpoints USB device into the pro-vided connection on the Quantum™.



• Any numerals that appear on the center line of this box, will represent units that have already been saved (from 0 to 99). If no units have yet been saved, the center line will be blank, and therefore there are no setpoints to delete.

• Enter a number on the keypad that corresponds to the unit number that you wish to delete, high-light the Ok button, then press [Enter]. You will be prompted with a new dialog box which will ask y ou OK to delete set number (0-99)?

• Highlight the Yes button, and press [Enter]. The dialog box will be updated with a new message stating that Set number (0-99) has been deleted!

ABOUT

DESCRIPTION: The About screen shows all Analog and Digital boards that have been detected by the Quantum™ LX, as well other related software information. the following information is shown here:

Linux Kernel - The Quantum™ LX controller runs on a Linux operating system (rather than Microsoft Windows). This is the software version number for the main Linux Kernel.

Software Version - This is the version of the software program that does the actual control of the Quantum™ LX. It runs in the Linux environment.

Sales Order - A six digit numerical value that has been assigned to a specific Evaporator package by Frick Com-pany. It is very important to have this number available when calling the factory for assistance or parts ordering.

Item - This is actually an extension of the Sales Order number. It would potentially be used for a site where the same Sales Order number was assigned for a variety of equipment. The Item Number would be different for each unit.

Analog Boards - Displays the analog board that were de-tected through communications at the last power up. If board were detected, the software version of the program running on that board (with date of the software) will be shown.

Digital Boards - Shows all digital boards that were de-tected through communications at the last power up. If boards were detected, the software version of the pro-gram running on that board (with date of the software) will be shown.

MISCELLANEOUS SCREENSAlpha

The Alpha screen shows a graphic representation of the Quan-tum™ LX numerical keypad. It is accessible from any screen that allows the user to enter alpha/numeric data, such as some of the Calibration screens, for example. The symbols that ap-pear above each key on this screen, are the possible combina-tions of symbols that are associated with the digital portion of the key. Pressing any of these keys repeatedly will cause the characters immediately above the keys on the keypad to ap-pear in the Current Character box. This is a similar technique that is used for sending text messages on a cellular phone.

As a example, suppose that you wanted to modify the text line in the screen example shown above. You want to change the line from reading Auxiliary Analog 1, to Packing Room 1. The first thing you would do, is to use the [Backspace] key on the keypad, to position the cursor (blinking vertical line), to the far left side of the text. Notice that each time the backspace key is pressed, the character to the left of the flashing cursor line is

erased. Once the flashing cursor is at the beginning of the line, press the number [6] key and notice that a capital P, for Pack-ing appears in the Current Character box (P is the first symbol in the line right above the numeral [6] key). When the letter that appears in the Current Character Box is the one that you wish to select, press the [^] key (up arrow) to copy the Current Character to the bottom text line. Next press the [7] key twice, and notice that on the first press, a capital A appears, and on the second press, a lower case a appears (for Packing).

Continue entering the text using this method. When you need to enter a space, simply press the [+/-] key once, then the [^] (up arrow), a space will be entered on the text line.

Finish all text entry, and when you are satisfied that it is what you want, press the [Enter] key, which will cause the text entry screen to be replaced by the previous screen, then press the [Submit] key to accept the changes.
