1.3 GENERAL PRODUCT DESCRIPTION The ADX Power Source is a high-performance AC power conversion instrument. It is intended for indoor use and the chassis is designed to fit into a standard 19 inch instrument rack or to be used on any test bench surface. The power source is suitable for use as a frequency converter as well as for sophisticated AC test power generation.

These power sources are configured with a digital controller. Controller type is a modified UPC1 version for sophisticated programmable control. This controller provides all of the manual control capability, plus a wide variety of additional features including program storage and remote interface (Serial standard or GPIB optional).

All ADX models have dual-range output voltage capability, able to operate at either 0-150 volts or 0-300 volts. When operated in the high voltage range, the output may be used as either a single-ended or split-phase configuration. The phase separation of L1 and L2 is fixed at 180 degrees in that case.

Output power is 1kVA at any nominal input voltage from 115 to 240 Vac.

External Voltage Sense capability is provided and will display the actual voltage at the remote sense location. The CSC (Continuous Self Calibration) feature will allow the controller to regulate the voltage at the sense location.(CSC)

Output voltage and current metering is provided on the system display. Specifications of the metering functions are described in the UPC Series Operation Manual.

Figure 1-1: 110ADX POWER SOURCE - FRONT VIEW


SECTION 2

SPECIFICATIONS

2 SPECIFICATIONS This section states the electrical and mechanical specifications of the ADX Power Source. Some specifications are controller dependent and are noted as such.

2.1 ELECTRICAL SPECIFICATIONS

2.1.1 INPUT POWER REQUIREMENTS The following input power forms are accepted by the ADX

INPUT VOLTAGE

The Model ADX accepts any single phase input voltage of 115-240 Vac, 50Hz or 60 Hz Nominal and is tolerant of transient overvoltages typically present on the AC MAINS power distribution lines.

INPUT CURRENT

The input current required by the ADX varies as a function of the nominal AC input line voltage applied. Input current at rated output power and recommended input service is shown in the table below. Overload conditions will result in higher input currents that still fall within the recommended input service. The AC input current is electronically limited at 25Arms. This allows full rated power down to 115V -10% or 103VAC L-N (Low Line Voltage).

NOTE: Under low voltage input conditions, the max input current is electronically limited to 25ARMS maximum. At least 12AWG input cable wire is recommended.

Vin INPUT CURRENT SERVICE RECOMMENDED

Table 2-2: RATED OUTPUT CURRENT BY MODEL

Refer to the Rating Curve charts of Figure 2-1 for maximum output current at a specific output form, voltage, or power factor by model number.

OVERLOAD OPERATION

The ADX Power Source can deliver up to 120% of rated RMS output current at 25°C ambient temperature with any input line voltage of 100 Vac or higher. Elevated ambient temperature, low input voltage, or power factors between 0.8 and 1.0 will increase the internal dissipation of the power source and can cause shutdown due to over-temperature conditions. Length of time to reach over-temperature varies with the above parameters.

NOTE: All ADX Models are equipped with an over power protection feature. See section 4.16 for more details.

2.3.3 INPUT POWER CONNECTION Input power is brought into the ADX at the Input Power terminal block on the rear panel.

2.3.4 OUTPUT POWER CONNECTION Output power is taken from the ADX Power Source via rear panel mounted terminal blocks. Remote Sense terminals are also provided at this terminal block.

Terminal block TB5 on the rear of the ADX may be used to remotely enable/disable the output of the power source. An electrical connection between terminals TB5-1 and TB5-3 enables the output of the ADX allowing normal operation from the front panel or remote interface. An open connection between TB5-1 and TB5-3, disables the output of the ADX. The ADX is supplied with a jumper installed in TB5 such that the output is enabled. That jumper may be replaced by a switch or relay which can operate as a safety interlock or remote disconnect.

2.3.5 CHASSIS SLIDE MOUNTS The ADX Power Source is designed to accept slide rails for mounting in a 19” Instrument Cabinet. These rack slides can be provided as a cost option. Contact your local sales representative or the Pacific Power Source Sales Office.

ADX SERIES MANUAL SECTION 3 INSTALLATION


Once the unit has been removed from its shipping container, select an appropriate location for the unit. Key points to consider when locating the chassis are:

1. PROXIMITY TO THE LOAD - The power source should be located as close to the load as possible. This helps to reduce distribution losses. These losses increase as the output frequency increases.

2. VENTILATION - The chassis requires good ventilation to adequately cool the internal components. Airflow should allow 240 CFM. The air intake is located on both sides near the front. A minimum clearance of two inches on each side and 12 inches to the rear is required for proper operation.

When the unit is placed in a 19 inch rack, it must be supported by either chassis slides or full depth angle brackets. The front panel alone will not support the weight of the chassis. Chassis slides are available from Pacific Power Source as a cost option. Call factory service for details.

After the location for the chassis is selected, verify that the input voltage of the power source is correct. Input voltage is stated on the system ID label.

After the input voltage form has been verified as correct, slide the chassis into the rack or set it into its final position. Make input and output connections as stated in paragraphs 3.3 and 3.4, respectively.

If either the Remote Interface (GPIB or RS-232) or External Sense feature is to be used, refer to paragraphs 3.5 and 3.7 for connection information.

Before activating the ADX output, check that the output voltage is correct to prevent possible damage to any attached equipment.

3.2 OUTPUT RANGE CONFIGURATION The ADX is a dual-range power source. The output voltage range is selected by the FORM setting selected in the UPC controller. See the UPC Series Operation Manual for setup. The standard output configurations are:

FORM 1: 0 – 150 Vac

FORM 2: 0 – 300 Vac

AMPS TO VOLTS RATIO:

For accurate current meter display, the Amps to Volts Ratio Setting of the UPC is always set to 5 for the Model ADX.



3.3 INPUT POWER CONNECTION The ADX Power Source has been designed to accept most standard single-phase input voltage forms. This is accomplished by incorporating an active wide-range power factor correction circuit. Any single-phase input voltage from 115 to 240 Vac ±10% can be applied. No range selection is required.

CAUTION PRECAUTION

CONNECTION OF THIS UNIT TO IMPROPER INPUT VOLTAGE

WILL CAUSE CATASTROPHIC DAMAGE TO THE POWER SOURCE. READ THE INPUT VOLTAGE LABEL AND CONNECT TO THAT INPUT VOLTAGE ONLY.

3.4 OUTPUT POWER CONNECTION The ADX provides output connections at both the front and rear of the chassis. Front panel load connection is through a universal outlet socket. Available current at this socket is 10 amps max., protected by a circuit breaker located at the rear of the unit. Rear panel load connection is available through a terminal block which is rated for the full output current of the ADX. Figure 3.3 illustrates connection of a single-phase load to the ADX rear-panel terminal. Refer to Paragraph 2.1.2 for minimum output service requirements for various output voltages and size the output wires accordingly.

NOTE: No metal parts should be touching the output terminals as dangerous voltage

may be present. It is the user's responsibility to meet all local and national electrical codes when installing this equipment.

For safe operation, the PE ground terminal should always be connected to the chassis of the load.

Output power should also be referenced to the chassis, unless otherwise demanded. The output is isolated but insulation specifications require that no more than 150 Vac be present between the output neutral (LINE2 or N) and chassis. For single-phase applications, a jumper should be attached between LINE2 and PE/GND. For applications using the high range as a split-phase configuration, the jumper should be attached between N and PE/GND.

Refer to Paragraph 3.7 for connection of the External Sense connection, when used.

The ADX Power Source output can be configured for single and split phase voltage forms. Figure 3.4 is a simplified block diagram of the possible output architectures.

The FORM1 (low range, 0-150 Vac) mode of operation is a one vector output form, single-phase only. The power amplifiers are connected in parallel to form one output vector. The load can be attached from LINE1 to LINE2 or LINE1 to N. In this form, LINE2 and Neutral are connected. This output form is capable of 0-150 VACl-n.

The FORM2 (high range, 0-300 Vac) mode of operation is a two vector output form where the vectors are separated by 180° and equal in amplitude. This output form uses power amplifiers in pairs, one for each vector.

For single phase 0-300 VACl-l, connect the load from LINE1 to LINE2.

For loads that require three connections (L1-N-L2), commonly referred to as "Split-Phase" power, LINE 1 and LINE 2 are equal in voltage and 180 degrees apart, referenced to Neutral. Loads can be connected from either LINE to Neutral or from LINE1 to LINE2.

3.5 REMOTE INTERFACE The ADX with the UPC Series programmable controller is supplied with an RS232 serial remote interface.

Interface Type Notes RS232 RS-232 Interface. D-Sub 9 Pin connector located on rear panel.

(Depicted in Figure 3.4) Pin out DB9 Connector: Pin 2: Receive Data Pin 3: Transmit Data Pin 5: Signal Ground All other pins are N/C

Table 3-1: RS232 PIN OUT

Connection and communication information relative to these interfaces can also be found in the UPC Series Operation Manual.

3.6 AUX I/O INSTALLATION On the rear panel J5, the AUX I/O (Auxiliary Input/Output) connector, contains synchronizing outputs (digital), external oscillator inputs (analog), and amplitude modulation inputs (AM, analog). These are extremely useful in certain test applications. The use of any of these signals is optional and connection to these points is required only when these features are used.

All signals contained within the AUX I/O connector are low-level (less than ±15 VDC) and are referenced to chassis (earth) ground reference.



The AUX I/O connector is a DB-25S connector. A DB-25P connector is required for connection to AUX I/O connector.

Figure 3-3: AUX I/O DB25S PIN OUT DIAGRAM



3.6.1 ANALOG INPUTS

Three Auxiliary Inputs are provided on J5, one per phase. The Auxiliary Inputs are AC coupled and algebraically summed to the Oscillator signals produced by the UPC. Note that the Auxiliary Inputs can be used as external oscillator inputs simply by programming the UPC for 0 VAC output.

Auxiliary Input voltage range (Vaux): ± 10Vpk (20Vpk-pk)

Input impedance: 600 ohms

Small Signal Gain Bandwidth: > 100 kHz. (auxiliary inputs)

Form 1:

Power source OUTPUT VOLTAGE = Vprogram + (Vaux x 25 x XFMRratio).

Form 2:

Power source OUTPUT VOLTAGE = Vprogram + (Vaux x 50 x XFMRratio).

Three AM Inputs are provided on J5, one per phase. Varying DC voltage may be used to Amplitude Modulate the output.

AM Input voltage range (Vam): ± 10Vdc (20Vpk-pk)

Input impedance: 600 ohms

Power source OUTPUT VOLTAGE = Vprogram + (Vam/10 x (204.5 x XFMRratio))

The maximum voltage is limited by the output voltage range of the power source

NOTE: Attempting to drive the OUTPUT VOLTAGE beyond the voltage range of the power source will result in a clipped (distorted) output waveform.

3.6.2 DIGITAL OUTPUTS

J5 digital outputs are 0 to 5 VDC, positive logic.

Logic outputs are:

Transient Pedestal: Not supported on ADX models

DRM: frequency generating clock, depending on FSPAN (4.6.4, 4.6.3.2)

SYNC OUT: Positive Zero Crossing (0º) of Phase A analog output



3.7 EXTERNAL SENSE CONNECTION The ADX Power Source includes connections for external sense of the output voltage. This allows measurement of the output voltage at an external sense point. This feature can be completely disabled, so the wiring detailed in this paragraph is optional.

Figure 3.4 shows external sense wiring for the ADX. There is very little current flowing through the External Sense Feedback lines. Standard 22 AWG, 600 Volt control wire is recommended for this application. Twisting the External Sense wiring is recommended and, in some cases, can improve performance. In noisy environments, shielding may become necessary to minimize interference. If shielded cable is used, be sure to ground the shield at one end only to prevent the possibility of creating a ground loop.

WARNING ATTENTION

LETHAL VOLTAGES ARE PRESENT AT THE OUTPUT TERMINALS OF THIS DEVICE! WHEN EXTERNAL SENSE IS CONNECTED, THE SAME VOLTAGE APPEARS ON THE SENSE TERMINALS.

SECTION 4

OPERATION

4 OPERATION This section describes the operation of the ADX AC Power Source UPC-1 controller.

4.1 OVERVIEW The ADX is operable either from its front panel keyboard (LOCAL CONTROL operation) or by its Data Bus (REMOTE CONTROL operation, Serial or IEEE-488/GPIB). A host computer can force REMOTE CONTROL when the ADX controller is displaying a Metering display. LOCAL CONTROL can be resumed either by a bus command (GoTo Local) or by manually pressing the LOCAL key. The host computer can force retention of REMOTE CONTROL by issuing a lockout command (Local LockOut (LLO), thereby preventing manual override.

When using the UPC controller, it is useful to think of it as being in one of 4 operating "modes" when in LOCAL CONTROL.

1. MANUAL OPERATE 2. PROGRAM OPERATE 3. PROGRAM EDIT 4. SETUP

MANUAL MODE is control of the operating characteristics via the front panel keyboard. Voltage and Frequency parameters are manually set from the front panel. Volts and Frequency may be directly entered through the numeric keyboard or they may be smoothly varied by use of the "slew" controls (up and down arrows). The V/I METER display (default display) shows both command values and metered values.

The PROGRAM OPERATE mode attempts to simplify certain test operations by allowing the operator to execute pre-stored setups (combinations of Volts, Frequency and Current limit). A stored program can be executed simply by pressing PROGRAM, entering a program number, then EXECUTE. Up to 99 programs can be stored as desired. After a program is called up by number, EXECUTE causes the base program parameters to be executed. These base parameters are commonly referred to as "Steady-state" parameters.

The PROGRAM EDIT mode allows the operator to create new programs, or change existing programs. It is noteworthy that programs other than any program actively executing, can be edited without disrupting power source output. For example, if program 15 is executing, program 23 can be edited without interrupting execution of program 15.

The SETUP MODE is used to make changes in system configuration. Examples are:

• Copy and Delete Programs • Set Min. and Max. Voltage Limits • Set Min. and Max. Frequency Limits • Engage and Disengage CSC (Continuous Self Calibration) • Set the Metering Sense Point – Internal or External • Set Slew rates • Change Frequency Span • Enable keyboard lockout • Set initial power on output voltage • Monitor Controller (UPC) and Power Source status • View Firmware Version

ADX SERIES MANUAL SECTION 4 OPERATION


• Enable Calibration Mode for Output and Metering • Set Serial Interface Parameters or GPIB Device Address • Erase Memory • Set Amps-to-Volts Current Metering Ratio

4.2 SELECTING OPERATING MODES On first turn-on the system will operate using a set of default parameters stored in memory. The display will be the V/I METER display. This is the default - and most frequently used - display. It shows all basic operating parameters, and in the lower left portion shows the operating mode. All operating modes can be accessed from the V/I METER display. If the V/I METER display is not active, pressing CLEAR a few times will always return to the V/I METER display.

MANUAL OPERATION (4.3) - is available by pressing V or F for voltage or frequency adjustments. An LED will light above a pressed key to indicate an active selection. The selected parameter can then be changed by typing a new value and pressing EXECUTE or holding one of the SLEW keys (︿ or ﹀).

PROGRAM OPERATION (4.4) -requires pressing PROGRAM, select a program number (1-99) and press ENTER to display the values stored in that program. Pressing EXECUTE will then cause the UPC to use those values. Note that pressing TRANS has no function on the ADX as this capability is not present.

PROGRAM EDIT (4.5) – is accessed by pressing PROGRAM, select a program number (1-99) and press ENTER to display the values stored in that program. Press EDIT to allow changes to the values stored in that program, ENTER to move the cursor through the screen, and STORE to save the values.

SETUP MODE (4.6) Pressing the fn key presents the menu list of SETUP features. It is used to copy and delete programs, erase memory, set meter sense points, toggle CSC on or off, min and max frequency and min and max voltage. Calibration for metering may also be performed. Status is given for system information such as firmware version, GPIB device address or Serial Interface parameters, transformer ratio, amps to volts ratio, number of Power Source amplifiers and current transformer location

NOTE: The five keys in the lower right portion of the keyboard (highlighted with a different color) are executive keys. Every attempt has been made to ensure that:

• In order to change power applied to the load one of these keys must be pressed.

• Whenever one of these keys is pressed, power to the load may be changed.

This operational feature has been designed to help keep the user from accidentally pressing the wrong key and unintentionally changing power to the load.

Remember! When you press a BLACK key something will probably happen to change output power.

ADX SERIES MANUAL SECTION 5 REMOTE CONTROL


4.3 FRONT PANEL CONTROLS

The location of the front panel controls and indicators of the ADX Power Source is shown below. A brief description of each is also given. Figure 4.1 is a front view of the ADX unit.

1. INPUT POWER SWITCH (Circuit Breaker @ 30A) Circuit Breaker used as the main input ON/OFF control and protects the power source from drawing excessive input current from the input AC line.

2. LCD Display. All settings and measurement data is display on the 4 x 40 character backlit LCD Display.

3. Numeric Keypad – Parameter values for any setting may be entered directly using the 0-9 keypad. A decimal point and a “+/-“ key is located in this area as well. The LOCAL/REMOTE, HELP, DISPLAY and FUNCTION (fn) key are located directly to the left of the numeric keypad.

4. EXECUTE, TRANS and OUTPUT ENABLE keys. Black keys are used to change the output. Note that the TRANS key functionality is not implemented in the ADX series.

5. OUTPUT ON/OFF Key. This switch opens the output relay and cannot be overridden by the remote control interface. It provides a means of physically disconnecting the power source from the load. This switch must be in the ON/AUTO position to control the output relay via either the OUTPUT ENABLE button or the remote control interface.

OUTPUT POWER SWITCH and INDICATORS Switch used to control the output relay of the ADX-Series Power Source. An indicator shows the status of the output. The power source will shut down for over-temperature or other internal faults if they occur. A shutdown state is reset when the Output Power Switch is set to OFF and the fault has cleared.

6. UNIVERSAL OUTLET SOCKET: This socket allows most plug to be used to connect a load. Note that this socket is fuse limited to 10A rms max. For full current output on higher power models, use the rear panel output terminals to connect the load.

4.10 SYSTEM SHUTDOWN This paragraph describes the conditions which will cause an automatic system shutdown and the procedure used to reset the ADX-Series Power Source.

WARNING ATTENTION

LETHAL VOLTAGES ARE PRESENT AT THE INPUT AND OUTPUT TERMINALS OF THIS EQUIPMENT!

DES TENSIONS A CARACTERE MORTEL SONT PRESENTES SUR LES BORNES D’ENTRÉE ET DE SORTIE DE CET EQUIPEMENT!



4.10.1 SHUTDOWN CONDITIONS

The Output Contactor of the ADX-Series Power Source will be opened automatically when:

1. Excessive temperature is detected. Either the input power circuit or one of the power amplifiers has become too hot. Over-temperature is usually caused by either an overload on the system output or restricted air-flow (air inlets may be blocked, dirty fan filters, or a clogged or non-functioning fan).

2. The Output FORM (UPC controller) has been changed. While the Output Contactor is engaged, any change of FORM, low range to high range or high range to low range, will force the unit to open the output contactor so that the range can be changed safely.

When the Output Contactor has been opened due to one of the above faults, the red SHUTDOWN LED on the front panel of the power source will be lighted. The output contactor will remain open while the SHUTDOWN LED is lighted. This LED will remain lighted until the unit is reset.

If the Output Power Switch is in the ON/AUTO position when the unit is turned on, the SHUTDOWN LED will light. This is normal operation. The LED is turned off simply by placing the Output Power Switch into the OFF position.

4.10.2 RESETTING SHUTDOWN FAULTS A shutdown fault is reset as follows:

1. Set the OUTPUT POWER Switch to the OFF position. If the unit is controlled through the remote (GPIB or RS-232) port, command the output OFF (:OUTP OFF).

2. Wait for the SHUTDOWN LED to extinguish. This LED will remain lighted until the condition which caused the shutdown to occur has been corrected. In the case of shutdown due to over-temperature this may take some time while the unit cools. The output contactor cannot be engaged until the shutdown fault has been cleared.

3. After the SHUTDOWN LED has been extinguished, the unit will function normally.

NOTE: The SHUTDOWN LED is latched ON when a fault occurs. The OUTPUT POWER Switch or the Output Enable of the UPC MUST be placed in the OFF position before the SHUTDOWN LED will extinguish, even if the original fault no longer exists.



4.11 OUTPUT VOLTAGE FORMS The ADX is a dual-range power source. The output voltage range is selected by the FORM setting selected in the UPC controller. See the UPC Series Operation Manual for setup. The standard output configurations are:

FORM 1: 0 – 150 Vac

FORM 2: 0 – 300 Vac

A recommended strategy for selecting the optimum output voltage form is to select the minimum voltage range necessary to drive the load. That will provide the maximum available current and allows the power source to operate more efficiently. This results in less heat being created within the unit.

4.12 AUDIBLE ALERT An audible alert within the ADX will sound to indicate any of several conditions:

1) When power is applied, it will “beep” 2X indicating normal start-up.

2) If the AutoStart option has been ordered, the unit will “beep” several times indicating normal start-up and activation of the unit output. Power may be present at the output terminals immediately, depending on the active program settings. See the Modification insert if applicable to your unit for more information.

3) During operation a steady tone may be produced, indicating one of the following operational limits has been exceeded:

• Input AC voltage is too high or too low; not within the 90-264 Vac specification.

• Input current has exceeded 25 Arms. This could occur at low input voltage and high power output combination.

• Output power demand exceeds the specified 120% overload condition.



4.13 CONSTANT CURRENT MODE The default mode of operation for the ADX is constant current mode. In this mode, the output voltage will be reduced once the set current limit is reached to maintain the current level drawn by the load. Once the load current demand drops below the set current limit level, the programmed output voltage is restored automatically. Thus, the AC Source continues to operate even if the UUT demands more current than the set current limit value. This current limit function is an average responding RMS current limit with a 50 msec response time. The current limit value can be set in the PROGRAM screen by entering the EDIT mode and using the ENTER key to scroll to the Ilim field value located at the bottom of this screen.

PROGRAM: #1 FROM=1 COUPLING=DIRECT FREQ=60.00 V=120.0 WF=1 #SEGS=0 Ilim=10.25

PROGRAM SCREEN Ilim SETTING NOTE: If the Ilim = value is set higher than the maximum available current for the range, the amplifier hardware limit will come in first so the Constant Current Mode does not engage.

Table 4-1: CURRENT PROTECTION - CC MODE



4.14 CONSTANT VOLTAGE MODE (CURRENT PROTECTION MODE) When the CURRENT PROTECTION feature is enabled, the ADX will operate in a constant voltage mode. In this mode, if the load current exceeds the set current protection limit (IprA) for a specified period of time, the power source will generate a fault condition and open the output relay of the power source. This disconnects the load from the AC Source. An error message will be displayed on the screen when this event occurs. The programmable delay may be used to allow ride-through of temporary inrush current events and prevent nuisance tripping in this mode of operation. The protection delay (IprT=) can be set by the user in 100 msecs steps from 100msec (1) to 109.22 mins (65535) When the System Output is disabled due to Current Protect, the UPC will display

“ERROR – CURRENT PROTECTION TRIGGERED”

Either the CLEAR or DISPLAY button must be depressed to clear the fault before the OUTPUT ENABLE switch will operate.

To avoid conflicts with the constant current mode of operation, the protection mode has to be enabled by the user. It can be toggled ON or OFF from the CURRENT PROTECT MENU which is reached by pressing function key fn followed by:

Press 3 for GENERAL SETUP Press 7 for MORE OPTIONS… Press 3 for CURRENT PROTECT

Notes: 1. During system operation, the UPC must be metering system output for Current Protect to

operate. Current Protect (as with voltage and current metering) is disabled during program edit or UPC Setup mode for firmware revisions 5.2.2 or lower.

2. When the System Output is disabled due to Current Protect, the UPC will display, “ERROR – CURRENT PROTECTION TRIGGERED”. Either the CLEAR or DISPLAY button must be depressed to clear the fault before the UPC32 OUTPUT ENABLE switch will operate.

3. It is recommended the Current Limit (Ilim) be set to a value greater than Current Protect (IprA). Setting current limit at or below current protect value will prevent Current Protect from disabling the power source output.



4.15 POWER PROTECTION MODE All ADX models are furnished with an over power protection mode. If for whatever reason the ADX source is delivering considerably more true power than its maximum rating, the unit will shut down to protect itself from damage. Trip levels are typically set at 130% of rating and a two second delay is imposed to avoid nuisance tripping during temporary overloads or power inrush conditions. If the total output power drawn by the load exceeds the power trip level in Watts, the output is turned off and the following error message will be displayed:

ERROR – POWER PROTECTION TRIGGERED P= 2500W OUTPUT NOW DISABLED

The power protection trip level differs for each ADX model as shown in the table below. MODEL OPP TRIP LEVEL 110ADX 1300 W 115ADX 1950 W

Table 4-3: POWER PROTECTION TRIP LEVELS BY MODEL

Upon a triggering an over power fault, the ADX can be cleared by pressing the CLEAR button and the output can be re-enabled using the OUTPUT ENABLE button.


SECTION 5

REMOTE CONTROL OPERATION

5 REMOTE CONTROL OPERATION This section describes remote control functions of the ADX UPC controller for communication over the IEEE-488 BUS or Serial Remote Interface. To select the proper commands for accurate setup and control of the UPC/power-source system, a thorough understanding of the UPC capabilities is needed. It is strongly recommended that the user read (4.0) (Front Panel Operation) to become familiar with the features and capabilities of the UPC.

Most commands listed in this section are also used with both the Serial and optional GPIB Remote Interface.

5.1 PREFACE For GPIB communications, REMOTE CONTROL is established when control or programming commands are sent to the ADX controller by a Bus Controller with REN (remote enable) set true. The REN line on the bus interface must be held TRUE to maintain REMOTE CONTROL. REMOTE CONTROL can only be initiated and maintained while the UPC is displaying a Metering display or while in the UPC STATUS display, but not while manually editing any screen data. All front panel programming and signal controls are disabled while REMOTE CONTROL is active, but metering information is still accessible for viewing at the front panel display.

NOTE: Status and metered data queries do not place the UPC into REMOTE CONTROL.

The front panel LOCAL key allows the user to restore LOCAL CONTROL unless the Bus controller has sent the IEEE-488 - LOCAL LOCKOUT (LLO) message. The Bus Controller may restore LOCAL CONTROL by sending the IEEE-488 - GOTO LOCAL (GTL) message.

NOTE: Pacific Power Source has Instrument drivers available for use with National Instruments LabWindows, and LabView programming environments. These software drivers simplify programming and control of the ADX power source via the REMOTE interface. A sample application, UPC Interactive, written in LabView, including the source code, is provided.



5.2 PROGRAMMING CONVENTIONS 1. COMMANDS are shown in the left hand column in BOLD, beginning with an asterisk ( * ) or

colon ( : ) text with NO underline.

2. Command DESCRIPTIONS appear in the right hand column.

3. SCPI is "Standard Commands for Programmable Instruments -1992". Refer to the SCPI 1992 standard for more information. The full standard publication is available from the IVI Foundation at http://www.ivifoundation.org/

4. Some SCPI keywords are optional, and are ignored by the device. Optional keywords are enclosed in [ ] brackets.

5. Lowercase letters of commands shown are also optional.

6. The SCPI 1992 standard requires uppercase text in all SCPI commands (start with : ), however, the UPC is not case sensitive and will accept commands sent in lower case. It is recommended that programming formats follow the SCPI standard.

7. All SCPI commands have query command counterparts unless noted. A query command consists of the command immediately appended with a question mark ( ? ). Values cannot be sent with a query. IEEE-488.2 commands do not have query counterparts unless explicitly shown with a question mark appended.

8. IEEE-488.2 commands start with an asterisk ( * ) and are not case sensitive.

9. All required Functional Elements for devices are implemented.

10. Refer to the ANSI/IEEE-488.1 1987 and ANSI/IEEE-488.2 1987 standards for more information.

11. All numerical values are ASCII encoded decimal strings consisting of 1 or more ASCII digits. 8 and 16 bit register values are binary weighted values represented by an ASCII string of 1 or more decimal digits. One exception, the Serial Poll byte, is an 8 bit hexadecimal byte.

12. Multiple Commands and Queries may be sent in one Program Message but each must be separated by a semicolon ( ; ). The term 'Program Message' refers to one or more commands and/or queries sent to the controller as one continuous string and is not to be confused with Stored Programs (1-99) within the controller.

13. Multiple data parameter names and values must be separated by commas.

14. Multiple keyword' messages may be sent without duplicating the first level SCPI keyword (i.e., SOURce). e.g., :SOURce:VOLTage1,120; FREQuency,60 A keyword is a single word beginning with a colon (:).

15. Program Messages MUST be terminated with a LINE FEED (0Ahex, 10dec) or END (EOI) signal. This is referred to as an end-of-string <eos>. A Carriage Return character (0Dhex, 13dec) is converted to a LINE FEED by the UPC. Further SCPI commands shall begin with a first level keyword (i.e.,:SOURce:).

16. All values shown in angle brackets <> are examples of real values used with commands but labels are sometimes used to indicate a variable which is not known until actual time of use. e.g., <AMPS meter range> might actually be <50>. Units such as AAC, Hz. or % shown after the angle bracketed value are not to be included inside the value, but are shown as a reference to the units. The angle brackets are not part of the value.

17. The controller data input buffer is 8k bytes, as is its data output buffer. No program message may exceed this length.

18. All :SOURce: commands also support query. An alternate method of writing or reading the

http://www.ivifoundation.org/

ADX SERIES MANUAL SECTION 6 MAINTENANCE

5.5.3 EVENT AND STATUS REPORTING Events and device Status may be queried by the Bus Controller through the following registers and queues. Query commands are explicitly shown in this section for clarity.

NOTE: It is recommended that reading EVENT and STATUS registers and queues occur in the following order. Reading any register or queue is optional. Indents indicate a hierarchy.

1. STB register, read via Serial Poll or *STB?.

2. ESR register, read via *ESR?.

3. SYSTem:ERRor? queue.

4. STATus:OPERation:EVENt? register.

5. STATus:QUEStionable:EVENt? register.

NOTE: For most applications, the STB register and SYSTem:ERRor queue will satisfy status and error reporting.

5.5.3.1 IEEE488.2 STATUS REPORTING Both IEEE-488 and serial port communications with UPC support the status reporting standards. Query commands are explicitly shown for clarity. Refer to the ANSI/IEEE-488.2 1987 standard for more information.

NOTE: <NRf> indicates Numeric Response format.

STATUS BYTE REGISTER (STB)

STATUS conditions reported by the STATUS BYTE may be queried via the IEEE-488 Bus Serial Poll function, or read directly using *STB?. The SRQ function will be invoked to signal the Bus controller that service is requested, when an unmasked STATUS BYTE bit goes true. Note that no SRQ is generated while in LOCAL CONTROL. *CLS clears the ESR and the STB (Figure 5.1).

The IEEE-488.2 Common Commands for Status Reporting from the UPC are:

BIT NAME DEFINITION 7 SOS :STATus:OPERation register bit summary 6 MSS/RQS - MASTER SUMMARY

summarizes all STATUS BYTE bits (except bit 6) for *STB?, or, - REQUEST SERVICE indicates the device requested service when Serial Poll was performed.

5 ESB STANDARD EVENT STATUS REGISTER bit summary 4 MAV MESSAGE AVAILABLE indicates Query response data is available 3 SQS :STATus:QUEStionable register bit summary 2 EEQ ERROR/EVENT QUEUE indicates an SCPI Error/Event message is

available 1 BUSY indicates UPC front panel not in V/I mode 0 SHUTDOWN indicates Power Source SHUTDOWN

Table 5-1: IEEE-488.2 STATUS BITS

Setting a SERVICE REQUEST ENABLE (SRE) bit true unmasks the STATUS bit in the STB. Bit 6 of the SRE is not applicable as the MASTER SUMMARY bit of the STB cannot be masked. The STB, SRE, ESR and ESE registers are 8 bits each.

STANDARD EVENT STATUS REGISTER (ESR)

Events reported by the STANDARD EVENT STATUS register may be queried via the *ESR? command. Reading the ESR register clears it. The EVENT STATUS summary bit in the STATUS BYTE (STB) will be set when an unmasked EVENT STATUS bit goes true.

BIT NAME DEFINITION 7 PON POWER ON indicates Input power was just applied 6 URQ USER REQUEST indicates "LOCAL" key was just pressed 5 CME COMMAND ERROR indicates invalid command or query received 4 EXE EXECUTION ERROR indicates can't execute command with data

received 3 DDE DEVICE DEPENDANT ERROR indicates UPC not properly configured 2 QYE QUERY ERROR indicates cannot respond with data 1 RQC REQUEST CONTROL - not used 0 OPC OPERATION COMPLETE indicates previous operation complete

Table 5-2: STANDARD EVENTS STATUS REGISTER (ESR) BITS

Setting an EVENT STATUS ENABLE (ESE) bit true unmasks the EVENT bit in the ESR. Also see :SYSTem:ERRor? query for corresponding information.

5.5.4 SCPI STATUS REPORTING The following lists the SCPI Commands for Status Reporting from the UPC. Refer to the SCPI 1992 standard for more information. Query commands are explicitly shown in this section for clarity (Figure 5-2). See (5.2) Conventions regarding SCPI.

:SYSTem:ERRor? Query: system error

Returns one of the following types of messages, with details appended to it if possible. A maximum of 256 characters may be sent as a response to this query.

-0, "No error" No error detected

-100, "Command error" indicates invalid command or query received

-200, "Execution error" indicates can't execute command with parameters received

-300, "Device-specific error" indicates UPC not properly configured

-400, "Query error" indicates query aborted

NOTE: The SYSTem:ERRor query clears the corresponding error bit in the ESR.

:SYSTem:VERSion? Query: SCPI version. Returns <1992.0>.

:SYSTem:SERIALNUMber? Query: Returns serial number string (1-15 characters). Note: The serial number is also displayed on the LCD display at power up.



The STATus:OPERation and STATus:QUEStionable registers provide information about the present mode of operation.

• Transition of a CONDition bit to the true state causes the EVENt bit to be set true. • Unmasked ENABle bits allow an EVENt bit to be reported in the summary bit for that

EVENt register in the STATUS BYTE register. • Setting an ENABLe bit true unmasks the corresponding EVENt bit. • Reading an EVENt register clears it. • All :STATUS registers are 16 bits.

The STATus:OPERation registers provide information about the present mode of operation.

NOTE: Most bits in the following :STATus registers are not applicable to the UPC but are shown for reference and may be used for future product enhancements. The PROGram running bit (14) in the :STATus:OPERation registers indicates a stored program (PROGRAM# 1-99) is running.

:STATus:OPERation:CONDition? present condition query.

:STATus:OPERation:ENABle enables events to be reported in the SOS bit in the STB.

:STATus:OPERation:ENABle? STAT:OPER:ENABLE register query.

:STATus:OPERation:EVENt? latched condition query. The STATUS:QUESTIONABLE registers provide information about errors and questionable measurements.

NOTE: All bits in the following :STATus registers are not applicable to the UPC but are shown for reference and may be used for future product enhancements.

:STATus:QUEStionable:CONDition? present condition query.

:STATus:QUEStionable:ENABle enables events to be reported in the SQS bit in the STB.

:STATus:QUEStionable:ENABle? STAT:OPER:ENABLE register query.

*LLO Command: LOCAL LOCKOUT. Puts the UPC into REMOTE mode and disables local operation of the UPC keyboard.

*GTL Command: GOTO LOCAL. Enables local operation of the UPC keyboard.

*DCL Command: DEVICE CLEAR. Performs a hardware RESET of the UPC.



5.7 REMOTE CONTROL EXAMPLES The REN (remote enable) line on the bus interface must be kept true to maintain REMOTE CONTROL. REMOTE CONTROL can only be initiated while the UPC is displaying a Metering display or while in the UPC STATUS display, not while editing.

See (3.5) for setting up the SERIAL INTERFACE parameters.

If the GPIB option is installed, be sure that the UPC GPIB device address is set to a known unique address within any GPIB system. The factory default device address is 1. See (4.6.5) for configuration of the GPIB device address.

Optional keywords have been omitted throughout this section for clarity. The command strings may contain spaces.

NOTE: Un-address means to send the UNTALK and UNLISTEN messages. This is only applicable for the GPIB, NOT the serial option. With many programming languages that support GPIB communications, listener and talker addressing and un-addressing is handled automatically and is transparent to the user. Check your programming language or driver documentation for verification.

NOTE: <eos> should be a LINE FEED (0Ahex, 10dec). See GPIB convention #15 (5.2) for more details.

CAUTION

ALL :SOURce PARAMETERS SHOULD BE SET PRIOR TO ENABLING THE OUTPUT FOR THE FIRST TIME

7.2.1 CONTROLLER CALIBRATION The first step in system calibration is to calibrate the UPC controller

To calibrate the ADX controller, it will be necessary to:

1. Set up the ADX to generate output voltage and current.

2. Measure the voltages and currents on all phases using an external Voltmeter and Current Meter that have been calibrated to a traceable standard (i.e., NBS, NIST), and are at least 2x as accurate as the ADX controller metering (see (2.1), SPECIFICATIONS)

3. Enter the measured values into the UPC via the keyboard or Remote Interface.

The ADX Controller then creates the required calibration factors (kFactors,) and stores them in memory. The kFactors can be viewed on the display by pressing fn, 4, 3, (7.2.2), or through the control bus (5.5.1), :CALibrate:KFACTORS).

Typically, calibration is performed with output settings of 60 Hz. and 120 volts. Because of the precision and stability of the system, the calibration factors are the same for all other values of volts and frequency. For convenience, or if precision at a particular setting is needed, the system may be calibrated at any frequency, voltage and current desired. Calibration of current metering is based on the Load Current set by the user. Therefore a nominal Load Current should be chosen for this calibration process.

NOTE: Only RMS voltages and currents are corrected.

WARNING

OBSERVE THE FOLLOWING WHEN CALIBRATION IS REQUIRED:

1) REMOVE ALL JEWELRY FROM ARMS AND NECK WHEN CALIBRATING EQUIPMENT. THIS PREVENTS THE POSSIBILITY OF SHORT CIRCUIT THROUGH THE JEWELRY, CAUSING BURNS TO, OR ELECTROCUTION OF, THE OPERATOR. 2) WEAR SAFETY GLASSES TO PREVENT EYE INJURY DUE TO FLYING PARTICLESCAUSED BY ACCIDENTAL SHORT CIRCUIT CONDITIONS.

3) DO NOT REMOVE ANY PANELS OR COVERS WITHOUT FIRST OPENING ALL CIRCUIT BREAKERS AND THEN REMOVING THE INPUT SERVICE.

To calibrate the ADX Controller:

1. Apply power to the power source and UPC.

2. Display the 'CALIBRATION' menu. Press fn, 4

CALIBRATION MENU: 1 RESET ALL KFACTORS 2 EXTERNALLY REFERENCED CALIBRATION 3 KFACTOR DISPLAY



3. Press 2 to select EXTERNALLY REFERENCED METER CALIBRATION

Ф INT.V-SENSE EXT.V-SENSE | I1 0.00 A 0.000 0.000 | Ia 0.00 B 0.000 0.000 | Ib 0.00 C 0.000 0.000 | Ic 0.00

4. Enter the measurements taken with external test equipment (voltmeter, ammeter) for each parameter shown on the UPC display. All measurements taken are to be AC RMS (True RMS metering is absolutely necessary), Line to Neutral only for voltages.

5. Upon completion, press EXECUTE.

The ADX controller has separate current metering circuits for FORM 1 (single phase) and for FORM 2. In order to fully calibrate all current meters for all power forms, this procedure must be performed twice.

1. Operate the power source in FORM 1 to calibrate I1 (single phase). 2. Operate the power source in FORM 2 (Vab) to calibrate Iab (single/split phase).

Only the phases existent need to have values entered. If a phase parameter is not used or is not available as in the case of a 1 or 2 phase power source, the phase C parameters should be set to 0. Entering 0 for a parameter causes the correction factor (kFactor) for that parameter to be set to the default value, 1.0000 .

NOTE: Only the values pertaining to the present output FORM will be displayed.

Voltages are AC RMS, LINE-NEUTRAL for FORM 1 & 3, LINE-LINE (A-B) FOR FORM 2 voltages.

Currents are AC RMS.

Each time a non-zero value is entered, the UPC measures the output signal for that parameter and compares it against the entered external meter calibration value. A new calibration factor (kFactor) is then calculated and used to correct the meter display for that value.

If a value for a parameter is not keyed in, the existing calibration factor will not be re-calculated. The correction factors are stored in Battery-backed memory (RAM) until the memory is lost or cleared.

7.2.2 K FACTOR DISPLAY

The correction factors (kFactors) created during EXTERNALLY REFERENCED CALIBRATION may be displayed or modified directly, from the kFactors display screen. Activate the CALIBRATION Menu (fn, 4), press 3 and the kFactor display appears as shown below.

(FORM 2 display shown).

Kin A:1.0000 B:1.0000 C:0.0000 Kex A:1.0000 B:1.0000 C:0.0000 Ki A:1.0000 B:1.0000 C:0.0000 Ko A:1.0000 B:1.0000 C:1.0000

Kin - are the kFactors for internal voltage sensing of phase A, B and C.

Kex - are the kFactors for external voltage sensing of phase A, B and C.

Ki - are the kFactors for current sensing of phase A, B and C.

Ko - are the oscillator gain kFactors.



It is recommended that the kFactors are reset to 1.000 before calibration. The new kFactor is then the ratio of the external metered value to the UPC meter display value. This minimizes error and will provide the best results.

new kFactor = ( test equipment value ) UPC meter display value To manually calculate and revise a particular existing kFactor,

1. observe the UPC meter display value 2. use the following equation to calculate the new kFactor:

new kFactor = old kFactor X ( test equipment value ) UPC meter display value

7.2.3 RESET ALL KFACTORS

Resets all kFactors to the factory default (1.000). Activate the CALIBRATION Menu (fn, 4), press 1 and the kFactor reset warning appears as shown below.

WARNING: RECALIBRATION REQUIRED PRESS "EXECUTE" TO CONTINUE PRESS "CLEAR" TO CANCEL

WARNING: You will have to recalibrate your power source.

7.3 POWER SOURCE LOAD TEST These tests are used to verify that the power source is able to deliver full rated output power. Additionally, the output metering function of the controller is also checked.

1. Set the Power Source for FORM2 Output, CSC Enabled.

ADX SERIES MANUAL SECTION 10 SERIAL REMOTE INTERFACE


SECTION 10

SERIAL REMOTE INTERFACE

10 SERIAL REMOTE INTERFACE This section describes using the optional Serial Remote Interface of the UPC. This section is intended to be used in conjunction with (5.0) of this Operation Manual.

10.1 GENERAL The Serial Remote Interface of the UPC is the standard communication port for the UPC-1. See (10.3) for setup information. An optional GPIB/IEEE-488 parallel communication port may be installed in place of the serial port. Check the connector label at the rear of the unit to determine which interface is installed.

10.2 SERIAL PORT SPECIFICATIONS The Serial Remote Interface of the UPC is compatible with the ANSI/IEEE-488.2, SCPI and RS-232C standards. It loosely adheres to the RS-232C standard as some interfacing requirements of that standard are not necessary.

This Remote Interface of the UPC has the following communication characteristics:

1. Selectable BAUD RATES of: 38400 BAUD 19200 BAUD (default) 9600 BAUD 4800 BAUD 2400 BAUD 1200 BAUD 300 BAUD

2. Selectable PARITY of ODD, EVEN or NONE (default).

3. Selectable EOS (End Of String) Terminator CR, LF or CR/LF (default): Sets the EOS sent from the UPC. The UPC accepts any of the above combinations when receiving.

4. 8 Data bits, 1 Start bit, 1 Stop bit.

5. HANDSHAKE: None.

Note: The Serial Remote interface of the UPC has no Handshake. This is a simple 2 wire interface.

6. Operation is HALF-DUPLEX (per IEEE-488.2).

Refer to (10.6) below for Pinouts and Signal names.


10.3 SETUP After installing the Serial Interface into the UPC - OR - after erasing all program memory – OR - after system RESET, the serial communication parameters must be set (BAUD RATE, PARITY and EOS Terminator) as follows:

1. Press the fn key, select GENERAL SETUP then UPC STATUS.

2. Press the EDIT key and type the desired BAUD RATE numerically, selected from the list above. Then press ENTER.

3. Select the PARITY by pressing the +/- key until the desired selection (NONE, ODD or EVEN) is shown. Then press ENTER.

4. Select EOS (End Of String) Terminator by pressing the +/- key until the desired selection (CR/LF, LF or CR) is shown. Then press ENTER.

5. Press STORE.

NOTE: Incorrect communication parameters may result in the UPC displaying a: PARITY ERROR, FRAMING ERROR, and/or OVERRUN ERROR.

Sending a BREAK signal will result in a BREAK RCVD message and will terminate data transmission in progress from the UPC.

10.4 OPERATION Operation of the UPC via Remote Serial Interface consists of utilizing the same commands available for the IEEE-488 interface (5.0) except as noted in (10.4.1), (10.4.2), and (10.4.3).

NOTE: Normally the UPC is in the LISTENER mode. When the UPC is Queried for information, the UPC automatically enters the Talker mode until the response data is sent or another command is sent from the Host.

10.4.1 COMMUNICATION MONITORING AID The UPC STATUS Display (fn,3,3) displays "LISTENER" while data is being received from the HOST, or "TALKER" if a Query response (Message Available) is available and has not yet been completely sent by the UPC.

The UPC STATUS Display will display the LAST DATA BYTE received from the HOST. Carriage Returns (0Dhex) are displayed as Line Feeds (0Ahex).

This monitoring aid is not updated as fast as serial communications can occur, therefore sudden changes on the Serial Interface may not be seen on the UPC display.

The ADX controller does not support RTS/CTS.



10.4.2 FUNCTIONAL EXCEPTIONS Some functions applicable with the IEEE-488 interface are NOT applicable with the Serial Interface. Specifically they are the following:

1. All IEEE-488.1 interface functions (5.6.1).

2. IEEE-488.2 commands: *SRE and *SRE?, are ignored, as Service Requests and Serial Polls are not applicable (5.5.3.1).

(Use *STB? to obtain the Status Byte.)

10.4.3 FUNCTIONAL ADDITIONS The following commands have been added to replace functions lost due to the removal of the IEEE-488.1 GPIB. These commands are similar to the IEEE-488.2 Common Commands and fall into the category of DEVICE CONTROL COMMANDS (5.6.2).

*DCL DEVICE CLEAR - Causes a Hardware RESET of the UPC. *LLO LOCAL LOCKOUT - Puts the UPC into REMOTE with LOCAL LOCKOUT state. *GTL GOTO LOCAL - Restores LOCAL mode.

10.5 PHYSICAL CONNECTIONS Connection to the UPC Serial Interface is made via a DB-25 connector on the rear panel of the UPC SCU or POWER SOURCE.

All other pins are reserved for future use.


10.6 TESTING THE SERIAL REMOTE INTERFACE 1. Connect the UPC Serial Interface to a DTE serial port of a PC using a DB-25 cable. Most 25

pin connectors on PC's are DTE type. The UPC is a DCE type and must connect to a DTE port. If using a 9 pin connector on the PC, verify the pinouts of the cable match the UPC to the PC correctly.

2. Configure the PC Baud Rate to 19200 or 9600 Baud, No Parity, 8 Data bits, 1 stop, 1 start bit using a terminal emulation program. Ensure the UPC is configured the same (see (10.3) of this manual for setup). Leave the EOS set to CR/LF.

3. Enter the UPC STATUS display of the UPC (fn,3,3), do NOT press EDIT this time. See (10.4.1) for info on the COMMUNICATION MONITORING AID.

4. Send Executable commands from the PC such as :SYST:BEEP, :VOLTS 100, :FREQ 50, and verify that the UPC responds correctly.

5. Send Query commands from the PC such as *IDN?, FETCH:VOLT1?, and verify that the PC receives correct data from the UPC after each Query command is sent. No other operation is needed to cause the UPC to send the response data.
