WARNING

3.9.1 Load Wiring

3.9.2 Current Carrying Capacity

at least

The following considerations should be made to select wiring for connecting the load to the power supply:

* Current carrying capacity of the wire (refer to 3.9.2) * Insulation rating of the wire should be at least equivalent to the maximum output voltage of

the power supply. * Maximum wire length and voltage drop (refer to 3.9.2) * Noise and impedance effects of the load wiring (refer to 3.9.4).

Twofactors must be considered when selecting the wire size:

1. Wires should be heavy enough not to overheat while carrying the power supply load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater.

3.8.7 Foldback Check

CAUTION

When local sensing, a short from +LS or +S to -V or -S or -LS, will cause damage to the power supply. Reversing the sense wires might cause damage to the power supply in local and remote sensing. (Do not connect -S to +V or +S to -V.)

Table 3-2: Maximum wire length for 1V drop on lead (in feet)

Table 3-3: Maximum wire length for 1V drop on lead (in meters)

2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated current. Although units will compensate for up to 5V in each load wire, it is recommended to minimize the voltage drop (1V typical maximum) to prevent excessive output power consumption from the power supply and poor dynamic response to load changes. Please refer to Tables 3-2 and 3-3 for maximum wire length to limit voltagedrop in American and European dimensions respectively.

3.9.3 Wire termination

The wires should be properly terminated with terminals securely attached. DO NOT use unterminated wires for load connection at the power supply.

3.9.4 Noise and Impedance Effects

3.9.5 Inductive loads

3.9.6 Making the load connections

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted- pairs to the shortest possible length. Shielding of sense leads may be necessary in high noise environments. Where shielding is used, connect the shield to the chassis via a rear panel Ground screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling, which might impact the stability of power supply. The sense leads should be separated from the power leads. Twisting the load wires reduces the parasitic inductance of the cable which could produce high frequency voltage spikes at the load and the output of power supply, because of current variation in the load itself. The impedance introduced between the power supply output and the load could make the ripple and noise at the load worse than the noise at the power supply rear panel output.Additional filtering with bypass capacitors at the load terminals may be required to bypass the high frequency load current.

Inductive loads can produce voltage spikes that may be harmful to the power supply.A diode should be connected across the output. The diode voltage and current rating should be greater than the power supply maximum output voltage and current rating. Connect the cathode to the positive output and the anode to the negative output of the power supply. Where positive load transients such as back EMF from a motor may occur, connect a surge suppressor across the output to protect the power supply. The breakdown voltage rating of the suppressor must be approximately 10% higher than the maximum output voltage of the power supply.

CAUTION

Ensure that the load wiring mounting hardware does not short the output terminals. Heavy connecting cables must have some form of strain relief to prevent loosening the connections or bending the bus-bars.

6V to 60V Models

Refer to Fig.3-5 for connection of the load wires to the power supply bus-bars and to Fig.3-6 for mounting the bus-bars enclosure to the chassis.

WARNING

Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

WARNING

Hazardous voltages exist at the outputs and the load connections. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

80V to 600V Models

Output Load Wires No Conductor Pretreatment: Phoenix Contact clamping parts are designed

so that all kinds of copper conductors can be clamped without pretreatment. It is forbidden to solder the conductors. The solder tin yields and fractures under high pressure. The result is increased contact resistance and an excessive temperature rise. In addition, corrosion caused by pickling or fluxes has been observed on soldered conductor ends. Notch fractures at the transition point from the rigid to the flexible conductor area are also possible.

3.9.8 Connecting single loads, remote sensing

Fig.3-11 shows recommended remote sensing connection for single loads. Remote sensing is used when, in Constant Voltage mode, the load regulation is important at the load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either at the power supply chassis or the load ground. The optimal point for the shield ground should be determined by experimentation.

3.9.10 Multiple load connection with distribution terminals

If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by a pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-13). If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.

3.9.11Grounding outputs

Either the positive or negative output terminals can be grounded. To avoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminal as close as possible to the power supply chassis ground. Always use two wires to connect the load to the power supply regardless of how the system is grounded.

WARNING

Models up to 60VDC Rated Output shall not float outputs more than +/-60VDC above/below chassis ground. Models > 60VDC Rated Output shall not float outputs more than +/-600VDC above/below chassis ground.

WARNING

OUTPUT TERMINAL GROUNDING

There is a potential shock hazard at the RS232/485 and the IEEE ports when using power supplies with rated or combined voltage greater than 400V with the Positive Output of the power supplies is grounded. Do not connect the Positive Output to ground when using the RS232/485 or IEEE under the above conditions.

3.10 LOCAL AND REMOTE SENSING

The rear panel J2 sense connector is used to configure the power supply for local or remote sensing of the output voltage. Refer to Fig.3-14 for sense connector location.

WARNING

There is a potential shock hazard at the sense connector when using a power supply with a rated output voltage greater than 40V. Local sense and remote sense wires should have a minimum insulation rating equivalent or greater than the maximum output voltage of the power supply. Ensure that the connections at the load end are shielded to prevent accidentalcontact with hazardous voltages.

3.10.2 Local sensing

The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the output voltage. See Table 3-4 for J2 terminals assignment. With local sensing , the output voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regulation is less critical.

WARNING

There is a potential shock hazard at the sense point when using power supply with a rated output voltage greater than 40V. Ensure that the connections at the load end are shielded to prevent accidental contact with hazardous voltages.

CAUTION

When using shielded sense wires, ground the shield in one place only. The location can be the power supply chassis or one of the output terminals.

3.10.3 Remote sensing

Use remote sense where the load regulation at the load end is critical. In remote sense, the power supply will compensate for voltage drop on the load wires. Refer to the power supply specifications

for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage available at the output. Follow the instructions below to configure the power supply for remote sensing:

1. Ensure that the AC On/Off is in the Off position.

2. Remove the local sense jumpers from J2.

3. Connect the negative sense lead to terminal J2-5 (-S) and the positive sense lead to terminal J2-1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely

into the rear panel sense connector,J2.

4. Turn On the power supply.

1. If the power supply is operating in remote sense and either the positive or negative load wire is not connected, an internal protection circuit will activate and shut down the power supply. To resume operation, turn the AC On/Off to the Off position, connect the open load wire, and turn On the power supply.

2. If the power supply is operated without the remote sense lines or local sense jumpers, it will

continue to work, but the output voltageregulation will be degraded. Also, the OVP circuit may activate and shut down the power supply.

CHAPTER 5 LOCAL OPERATION

5.1 INTRODUCTION

5.2 STANDARD OPERATION

This Chapter describes the operating modes that are not involved in programming and monitoring the power supply via its serial communication port (RS232/RS485) or by remote analog signals. Ensure that the REM/LOC LED on the front panel is Off, indicating Local mode. If the REM/LOC LED is On, press the front panel REM/LOC button to change the operating mode to local.

- For information regarding remote analog programming refer to Chapter 6.

- For information regarding usage of the serial communication port refer to Chapter 7.

The power supply has two basic operating modes: Constant Voltage Mode and Constant Current Mode. The mode in which the power supply operates at any given time depends on the output voltage setting, output current limit setting and the load resistance.

1. In constant voltage mode, the power supply regulates the output voltageat the selected value, while the load current varies as required by the load.

2. While the power supply operates in constantvoltage mode, the VOLTAGE LED on the front panel

illuminates.

3.Adjustment of the output voltage can be made when the power supply output is enabled (Output On) or disabled (Output Off).When the output is enabled, simply rotate the VOLTAGE encoder knob to program the output voltage. When the output is disabled, press the PREV button and then rotate the VOLTAGE encoder knob. The VOLTAGE meter will show the programmed output voltage for 5 seconds after the adjustment has been completed.Then the VOLTAGE meter will display "OFF".

4.Adjustment resolution can be set to coarse or fine resolution.

Press FINE button to select between the lower and higher resolution. The FINE LED turns On when the resolution is set to FINE.

5.2.1 Constant Voltage Mode

If after completing the adjustment, the display shows a different value than the setting, the power supply may be at current limit. Check the load condition and the power supply current limit setting.

The maximum and minimum setting values of the output voltage are limited by the Over Volt

age protection and Under Voltage limit setting.

Refer to Sec.5.3 and 5.4 for more details.

NOTE

5.2.2 Constant Current Operation

1. In constant current mode, the power supply regulates the output current at the selected value, while the voltage varies with the load requirement.

2. While the power supply is operating in constant current mode, the CURRENTLED on the front

panel illuminates.

3.Adjustment of the output current limit can be made when the power supply output is enabled

(Output On) or disabled (Output Off).

- Disabled output (Off): Press PREV button and then rotate the Current encoder knob. The CURRENT meter will show the programmed current limit for 5 seconds after the adjustment has been completed. Then the VOLTAGE meter will display "OFF".

- Enabled output, power supply in Constant Voltage mode: Press the PREV button and then rotate the CURRENT encoder knob. The CURRENT meter will show the programmed current limit for 5 seconds after the adjustment has been completed, and then will return to show the actual load current.

- Enabled output, power supply in Constant Current mode: Rotate the CURRENT encoder knob to adjust the current limit.

4. Adjustment resolution can be set to Coarse or Fine adjustment. Press the FINE button to select between the Coarse and Fine resolution. The FINE LED turns On when the resolution is set to FINE.

If the power supply operates in Constant Voltage mode, while the load current is increased to greater than the current limit setting, the power supply will automatically switch to Constant Current mode. If the load is decreased to less than the current limit setting, the power supply will automatically switch back to Constant Voltage mode.

The OVP circuit protects the load in the event of a remote or local programming error or a power supply failure. The protection circuit monitors the voltage at the power supply sense points and thus providing the protection level at the load. Upon detection of an Over Voltage condition, the power supply output will shut down.

The OVP can be set when the power supply output is Enabled (On) or Disabled (Off). To set the OVP level, press the OVP/UVL button, so that the CURRENT meter shows "OUP".

The VOLTAGE meter shows the OVP setting level. Rotate the VOLTAGE encoder knob to adjust the OVP level. The display will show "OUP" and the setting value for 5 seconds after the adjustment has been completed and then will return to it's previous state.

The minimum setting level is approx. 105% of the set output voltage, or the value in Table 7-6, whichever is higher.The maximum setting level is shown in Table5-1.

5.3.3 Resetting the OVP circuit

When the OVP is activated the power supply output

shuts down. The VOLTAGE display shows

"OUP" and the ALARM LED blinks.

To reset the OVP circuit afterit activates:

1. Reduce the power supply Output Voltage setting below the OVP set level.

2. Ensure that the load and the sense wiring is connected properly.

3. There are four methods to reset the OVPcircuit.

3.1 Press OUT button.

3.2 Turn the power supply Off using theAC On/Off switch, wait until the front panel display turns

Off, then turn the power supply On using theAC On/Off switch.

3.3 Turn the power supply output Offand then On using the SO control (refer to sect.5.7). In this

method the power supply should be set to Auto-Restart mode.

3.4 Send OUT1 command via the RS232/485 communication port.

5.5 FOLDBACK PROTECTION

5.6 OUTPUT ON/OFF CONTROL

5.7 OUTPUT SHUT-OFF (SO) CONTROL VIA REAR PANEL J1 CONNECTOR

The UVL prevents adjustment of the output voltage below a certain limit.The combination of UVL and OVP functions, allow the user to create a protection window for sensitive load circuitry.

Setting the UVL can be made when the power supply output is Enabled (On) or Disabled (Off). To set the UVL level, press the OVP/UVL button TWICE, so that the CURRENT meter shows “UUL”. The VOLTAGE meter shows the UVL setting level. Rotate the VOLTAGE encoder knob to adjust the UVL level. The display will show “UUL” and the setting value for 5 seconds after the adjustment has been completed and then will return to it’s previous state. UVL setting values are limited at the maximum level to approximately 95% of the Output Voltage setting. Attempting to adjust the UVL above this limit will result in no response to the adjustment attempt. The minimum UVL setting is zero.

5.4.1 Setting the UVL level

Foldback protection will shut down the power supply output if the load current exceeds the current limit setting level. This protection is useful when the load circuitry is sensitive to an over current condition.

To arm the Foldback protection, the FOLD button should be pressed so that the FOLD LED illuminates. In this condition, transition from Constant Voltage to Constant Current mode will activate the Foldback protection. Activation of the Foldback protection disables the power supply output, causes the ALARM LED to blink and display " Fb" on the VOLTAGE meter.

There are four methods to reset an activated Foldback protection.

1. Press the OUT button. The power supply output is enabled and the Output Voltage and current will return to their last setting. In this method, the Foldback protection remains armed, therefore if the load current is higher than the current limit setting, the Foldback protection will be activated again.

2. Press the FOLD button to cancel the Foldback protection. The power supply output will be disabled

and the VOLTAGE display will show “OFF”. Press the OUTbutton to enable the power supply output.

3. Turn the power supply output Off and then On using the SO control (refer to sect. 5.7). In this method the foldback protection remains armed, therefore if the load current is higher than the current limit setting the Foldback protection will be activated.

4. Turn the power supply Offusing the AC On/Off switch, wait until the front panel display turns Off, then turn the unit back ON again. The power supply output is enabled and the Output Voltage and Current will return to their last setting. In this method, the Foldback protection remains armed, therefore if the load current is higher than the current limit setting, the Foldback protection will be activated again.

The Output On/Off enables or disables the power supply output. Use this function to make adjustments to either the power supply or the load without shutting off the AC power. The Output On/Off can be activated from the front panel using the OUT button or from the rear panel J1 connector.The OUT button can be pressed at any time to enable or disable the power supply output. When the output is disabled, the output voltage and current fall to zero and the VOLTAGE display shows “OFF”.

Contacts 2,3 and 15 of J1 (Fig.4-2, Item 5) serve as Output Shut-Off (SO) terminals. The SO terminals

accept a 2.5V to 15V signal or Open-Short contact to disable or enable the power supply output. The SO function will be activated only when a transition from On to Off is detected after applying AC power

to unit. (Thus , inAuto-Restart mode, the output will be enabled after applying AC power, even if SO is in Off level.). After On to Off transition is detected, the SO will enable or disable the power supply output according to the signal level or the short/open applied to J1.This function is useful for connecting power supplies in a “Daisy-chain” (refer to section 5.16). The SO control can be used also to reset the OVP and Fold Protection. Refer to sect. 5.3 and 5.5 for details.

5.5.1 Setting the Foldback protection

5.5.2 Resetting activated Foldback protection

When the unit is shut-off by J1 signal, the VOLTAGE display will show “SO” to indicate the unit state. J1 contact 15 is the SO signal input and contacts 2 and 3, IF_COM, are the signal return (connected internally). Contacts 2,3 and 15 are optically isolated from the power supply output. The SO control logic can be selected by the rear panel SW1 Setup switch. Refer to Table 5-2 for SW1 setting and SO control logic.

5.9 CV/CC SIGNAL

5.10 PS_OK SIGNAL

CV/CC signal indicates the operating mode of the power supply, Constant Voltage or Constant Current. CV/CC signal is an open collector output with a 30V parallel zener, at J1-13, referenced to the COM potential at J1-12 (connected internally to the negative sense potential). When the power supply operates in Constant Voltage mode, CV/CC output is open. When the power supply operates in Constant Current mode, CV/CC signal output is low(0-0.6), with maximum 10mA sink current.

PS_OK signal indicates fault condition in the power supply. PS_OK is a TTL signal output at J1-16, referenced to IF_COM at J1-2,3 (Isolated Interface Common)). When a fault condition occurs, PS_OK level is low, with maximum sink current of 1mA, when no fault condition occurs, PS_OK level is high with maximum source current of 2mA. The following faults will set the PS_OK to Fault state:

Safe Startmode-If the Enable/Disable fault condition clears when units in safe start mode

recovery is by pressing OUT button or by sending a ‘OUT 1’ serial command.

Auto Restart mode-The output will return back ON automatically when the Enable/Disable

fault conditions clears.

To prevent possible damage to the unit, do not connect any of the Enable/Disable inputs to the positive or negative output potential.

CAUTION

Do not connect CV/CC signal to a voltage source higher than 30VDC. Always connect CV/CC signal to the voltage source with a series resistor to limit the sink current to less than 10mA.

When turning on the power supply AC On/Off, it can start to its last setting of Output Voltage and

Current limit with the output enabled (Auto-restart) or start with the output disabled (Safe mode).

Press and hold the OUT button to select between Safe start and Auto-restart modes. The VOLTAGE

display will continuously cycle between "SAF" and "AU7” every 3 seconds. Releasing OUT

pushbutton while one of the modes is displayed, selects that mode. The default setting at shipment

is Safe mode.

In this mode, the power supply restores its last operation setting. Upon start-up, the output is

enabled or disabled according to its last setting.

In this mode, the power supply restores its last operation setting and sets the Output to Off state. At

start-up, the output is disabled and the output voltage and current are zero. To enable the output and restore the last output voltage and current limit values, momentarily press OUTbutton.

The OTP circuit shuts down the power supply before the internal components can exceed their safe internal operating temperature. When an OTP shutdown occurs, the display shows "O7P" and the ALARM LED blinks. Resetting the OTP circuit can be automatic (non-latched) or manual (latched) depending on the Safe or Automatic restart mode.

In Safe start mode, the power supply stays off after the over temperature condition has been removed. The display continue to shows "O7P" and theALARM LED continues to blink. To reset the OTP circuit, press OUT button (or send OUT ON command via the serial port).

InAuto-restart mode , the power supply recovers to it's last setting

automatically when the over temperature condition is removed.

When power supplies are connected in series, and the load or one of the output terminals is grounded, no point may be at a greater potential of +/-60VDC from ground for models up to 60VDC Rated Output and +/-600VDC from ground for models >60VDC Rated Output. When using RS232/485 or IEEE, refer to the OUTPUT TERMINALS GROUNDING warning, section 3.9.11.

5.14.1 Series connection for increased output voltage

In this mode, two units are connected so that their outputs are summed. Set the current limit of each power supply to the maximum that the load can handle without damage. It is recommended that diodes be connected in parallel with each unit output to prevent reverse voltage during start up sequence or in case one of the units shuts down. Each diode should be rated to at least the power supply rated output voltage and output current. Refer to Fig.5-1 and 5-2 for series operation with local and remote sensing.

5.15 PARALLEL OPERATION

Up to four units of the same VOLTAGE and CURRENT rating can be connected in parallel to provide up to four times the output current capability. One of the units operates as a master and the remaining units are slaves. The slave units are analog programmed by the master unit.

In remote digital operation, only the master unit can be programmed by the computer while the slave units may be connected to the computer for voltage,current and statusreadback only.

There are two methods, basic and advanced, to configure multiple supplies for parallel operation. Refer to Sec. 5.15.1 and to Sec. 5.15.2 for detailedexplanation.

In this method, setting the units as Master and Slaves is made by the rear panel J1 connections and the setup switch SW1. Each unit displays its own output current and voltage. To program the load current, the Master unit should be programmed to the total load current divided by the number of units in the system. Refer to the following procedure to configure multiple supplies for simple parallel operation.

5.15.1 Basic parallel operation

5.15.2 Advanced parallel operation

1. Basic configuration

In this method, multiple supplies can be configured to parallel operation as a single power supply. The total load current and output voltage are displayed by the Master unit and can be readback from the Master unit. The Slave units display only their operating status (On, Off or Fault condition). Refer to the following procedure to configure multiple supplies for Advanced parallel operation.

Repeat steps 1 to 5 in Sec. 5.15.1 (Basic parallel operation).

1. Setting up the Master unit

2. Setting up the slave units

3. Setting Over Voltage protection

4. Setting Foldback protection

5. Connection to the load

Set the master unit output voltage to the desired voltage. Program the current limit to the desired load current limit divided by the number of parallel units. During operation, the master unit operates in CV mode, regulating the load voltage at the programmed output voltage. Connect the sensing circuit to local or remote sensing as shown in Fig.5-4 or Fig.5-5.

-1.The output voltage of the slave units should be programmed 2%~5% higher than the output voltage of the master unit to prevent interference with the master unit's control. The current limit of each unit should be programmed to the desired load current limit divided by the number of parallel units.

-2.Set the rear panel setup switch SW1 position 2 to it's up position.

-3.Set the rear panel setup switch SW1 position 3 in the same position as

SW1 position 4 of the master.

-4.Connect short between J1-8 and J1-12 (refer to Table 4-4.)

-5. Connect J1 terminal 10(IPGM) of the slave unit to J1 terminal 25(P) of the master unit.

During operation the slave units operate as a controlled current source following the master output current. It is recommended that the power system is designed so that each unit supplies up to 95% of its current rating because of the imbalance which may be caused by cabling and connections voltage drop.

The master unit OVP should be programmed to the desired OVP level. The OVP of the slave

units should be programmed to a higher value than the master OVP. When the master unit shuts down, it programs the slave unit to zero output voltage. If a slave unit shuts down (when its OVP is set lower than the master output voltage), only that unit would shut down and the remaining slave units would supply all the load current.

Foldback protection if desired, may only be used with the master unit. When the master unit shuts down it programs the slave units to zero output voltage.

In parallel operation, power supplies can

be connected in local or remote sensing. Refer to Fig.5-4 and 5-5 for typical connections of parallel power supplies. The figures show connection of two units, however the same connection method applies up to 4 units.

2. Setting the units as Master or Slave

3. Master and Slave units default operation

4. CURRENT display accuracy

5. To release units from Slave mode

a) Depress and hold the FINE button for 3 seconds. The Master/Slave configuration will be displayed on the Current Display. Rotate the CURRENT encoder to obtain the desired mode. Refer to Table 5-4 for the CURRENT display and modes of operation.

b) When the desired configuration is obtained, depress and release the FINE button or wait approx. 5 seconds.

a) When a unit is programmed to Slave mode it enters the Remote mode with Local Lockout,

then all the front panel controls are disabled to prevent accidental setting change.

b) The Slave units parameters will automatically set the following:

*Output voltage to approximate. 102% of rated output voltage. *Programmed Current to zero. *UVL to zero volts *OVP to its maximum value

c) The Master and Slave modes are stored in the power supply EEPROM when the AC power is

Turned off. The system will return to the Master/Slave mode upon re-application of AC power.

In the advanced parallel mode, the total current is programmed and reported by the Master. In this method, the CURRENT display accuracy is 2%+/- 1 count. In cases that higher accuracy is required, it is recommended to use the basic parallel operation mode.

Slave units can be released using the following procedure: a) Depress FINE button for 3 seconds. The Master/Slave configuration will be displayed on the

CURRENT display. b) Select H1 mode using the CURRENT encoder. c) Depress FINE button again or wait 5 seconds. d) Turn the AC power Off to store the new setting. e) After exiting from Slave operation the unit’s parameters will be set to:

CAUTION

Make sure that the connection between -Vo terminals is reliable to avoid disconnection during operation. Disconnection may cause damage to the power supply.

With local sensing it is important to minimize the wire length and resistance. Also the positive and negative wire resistance should be close as possible to each other to achieve current balance between power supplies.

NOTE

5.16 DAISY-CHAIN CONNECTION

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units. When the fault is removed, the system recovers according to its setting to Safe start mode or Automatic restart. Setup switch SW1 position 5 should be set to its Down position to enable the Daisy-chain operation. Other SW1 positions can be set according to the application requirements. If a fault occurs in one of the units its PS_OK signal will be set to low level and the display will indicate the fault. The other units will shut off and their display will indicate "SO”. When the fault condition is removed, the units will recover to their last setting according to their Safe start or Auto-restart setting. Fig.5-6 shows connection of three units, however the same connection method applies to systems with a larger number of units.

CHAPTER 6 REMOTE ANALOG PROGRAMMING

6.1 INTRODUCTION

The rear panel connector J1 allows the user to program the power supply output voltage and current limit with an analog device. J1 also provides monitoring signals for output voltage and output current. The programming range and monitoring signals range can be selected between 0-5V or 0-10V using the setup switch SW1. When the power supply is in Remote Analog programming, the serial communication port is active and can be used to read the power supply parameters.

CAUTION

COM (J1-12), VPGM_RTN (J1-22) and IPGM_ RTN (J1-23) terminals of J1 connect internally to the -Sense potential (-S). Do not connect these terminals to any potential other than -Sense (-S), as it may damage the power supply.

6.2 LOCAL /REMOTE ANALOG SELECTION

Contact 8 of J1 (Fig. 4-2, item 5) accepts TTL signal or Open-Short contact (referenced to J1-12) to select between Local or Remote Analog programming of the output voltage and current limit. In Local mode, the output voltage and current limit can be programmed via the front panel VOLTAGE and CURRENT encoders or via the RS232/485 port. In Remote Analog mode, the output voltage and current limit can be programmed by analog voltage or by programming resistors via J1 contacts 9 and 10 (refer to sec. 6.4 and 6.5). Refer to Table 6-1 for Local/Remote Analog control (J1-8) function and Setup switch SW1-1, 2 setting.

6.3 LOCAL/REMOTE ANALOG INDICATION

Contact 21 of J1 (Fig. 4-2, item 5) is an open collector output that indicates if the power supply is in Local mode or in Remote Analog mode. To use this output, connect a pull-up resistor to a voltage source of 30Vdc maximum. Choose the pull-up resistor so that the sink current will be less than 5mA when the output is in low state. Refer toTable 6-2 for J1-21 function.

Perform the following procedure to set the power supply to Remote Voltage programming :

1. Turn the power supply AC On/Off switch to Off.

2. Set setup switch SW1-1 to its UP position for output voltage external programming and SW1-2 to its UP position for Output Current limit external programming.

3. Set SW1 position 3 to select programming voltage range according to Table 6-3.

4. Ensure that SW1 positions 7 and 8 are at their Down (default) position.

5. Connect a short between J1-8 and J1-12 (refer to Table 4-4).

6. Connect the programming source to the mating plug of J1 as shown in Fig.6-1. Observe correct polarity for the voltage source.

7. Set the programming sources to the desired levels and turn the power supply ON. Adjust the programming sources to change the power supply output.

1. SW1 positions 4,5,6 and 9 are not required for remote programming. Their setting can be determined according the application.

2. The control circuits allow the user to set the output voltage and current limit up to 5% over the model-rated maximum value. The power supply will operate within the extended range, however it is not recommended to operate the power supply over its voltage and current rating and performance is not guaranteed.

NOTES:

6.5 RESISTIVE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT

For resistive programming, internal current sources, for output voltage and/or output current control, supply 1mA current through external programming resistors connected between J1-9 & 22 and J1-10 & 23. The voltage across the programming resistors is used as a programming voltage for the power supply. Resistance of 0~5Kohm or 0~10Kohm can be selected to program the output voltage and current limit from zero to full scale. A variable resistor can control the output over its entire range, or a combination of variable resistor and series/parallel resistors can control the output over restricted portion of its range.

Perform the following procedure to set the power supply to Resistive programming:

1. Turn the AC On/Off switch to Off.

2. Set setup switch SW1-1 to its UP position for output voltage external programming and SW1-2 to its UP position for Output Current limit external programming.

3. Set SW1 position 3 to select programming resistor range according to Table 6-4.

4. Set SW1-7 to its UP position for output voltage resistive programming and SW1-8 to its UP position for Output Current limit resistive programming.

5. Connect a short between J1-8 and J1-12 (refer to Table 4-4).

6. Connect the programming resistors to the mating plug of J1 as shown in Fig.6-2.

7. Set the programming resistors to the desired resistance and turn the power supply ON.

Adjust the resistors to change the power supply output.

1. SW1 positions 4, 5, 6 and 9 are not required for remote programming. Their setting can be determined according to the application requirements.

3. To maintain the temperature stability specification of the power supply, the resistors used for programming should be stable and low noise resistors, with temperature coefficient of less than 50ppm.

4. When resistive programming is used, front panel and computer control (via serial communication port)

of output voltage and current are disabled.

6.6 REMOTE MONITORING OF OUTPUT VOLTAGE AND CURRENT

The J1 connector, located on the rear panel provides analog signals for monitoring the output voltage and output current. Selection of the voltage range between 0-5V or 0-10V is made by setup switch SW1-4. The monitoring signals represent 0 to 100% of the power supply output voltage and output current.The monitor outputs have 500 ohm series output resistance. Ensure that the sensing circuit has an input resistance of greater than 500 Kohm or accuracy will be reduced. Refer to Table 6-5 for required J1 connection, SW1-4 setting and monitoring voltage range.

- Down for RS232

- Up for RS485

Five optional rates are possible: 1200, 2400, 4800, 9600 and 19200. To select the desired rate, the following steps should be taken:

1. If the unit is in Remote mode (front panel REM/LOC LED illuminates), press REM/LOC button to put the unit into Local mode.

2. Press and hold for approx. 3sec. the REM/LOC button. The CURRENT display will show the communication port Baud Rate.

3. Using the CURRENT adjust encoder, select the desired Baud Rate.

1. The unit will be put into Remote mode only via serial communication command. Commands that will put the unit into Remote mode are:

RST PV n OUT n PC n RMT n (for n values see Tables 7-3, 7-4 and 7-5)

-Address:

-Baud-rate:

-RS232/485:

-Vout setting:

-Iout setting:

-Master/Slave

2. There are two Remote modes:

1. Remote:

2. Local Lockout:

In this mode, return to local can be made by the front panel REM/LOC or via serial port command RMT 0. Set the unit into Remote mode via serial port

RMT 1 command.

In this mode the unit can be returned to Remote mode via the serial port RMT 1 command or by turning off the AC power until the display turns off and then turn it to on again. In Local Lockout mode, the front panel REM/LOC button is not active. Set the unit into Local Lockout mode via serial port RMT 2 command.

7.2.6 RS232/485 port in Local mode

7.2.7 Front panel in Remote mode

When the power supply is in local mode, it can receive queries or commands. If a query is received, the power supply will reply and remain in Local mode. If a command that affects the output is received, the power supply will perform the command and change to Remote mode. Serial commands may be sent to set the status registers and read them while the unit is in Local mode. If the Enable registers are set (refer to section 7.8) the power supply will transmit SRQ’s while in Local.

Front panel control in Remote mode is disabled except for:

1. PREV: use to preview the Voltage and Current limit setting.

2. OVP/UVL: use to preview the OVP/UVL setting.

3. LOC/REM: use to set the unit into Local mode.

In Local Lockout mode, only PREV and OVP/UVLare active.

The RS232/485 interface is accessible through the rear panel RS232/485 IN and RS485 OUT connectors. The connectors are 8 contact RJ-45. The IN and OUT connectors are used to connect power supplies in a RS232 or RS485 chain to a controller. Refer to Fig.7-1 for IN/OUT connectors

7.3 REAR PANEL RS232/485 CONNECTOR

Serial data format is 8 bit, one start bit and one stop bit. No paritybit.

The Address is sent separately from the command. It is recommended to add a 100 msec software delay between query or sent command to next unit addressing.

Refer to section 7.7.3 for details.

The end of message is the Carriage Return character (ASCII 13). The power supply ignores the Line Feed (ASCII 10) character.

The backslash character “\” will cause the last command to be repeated.

The user may optionally add a checksum to the end of the command. The checksum is "$" followed by two hex characters. If a command or a query has checksum, the response will also have one. There is no CR between the command string and the "$" sign. Example: STT?$3A

STAT?$7B

The power supply acknowledges received commands by returning "OK" message. If an error is detected, the power supply will return an error message. The rules of checksum apply also to the acknowledge.

7.8 STATUS, ERROR AND SRQ REGISTERS

This section describes the various status error and SRQ registers structure. The registers can be read or set via the RS232/485 commands. When using the IEEE option, refer to the user manual

for Genesys Power Supply IEEE Programming interface. Refer to Fig.7-7 for the Status and Error Registers Diagram.

7.8.1 General

Fig.7-7: Status and Error Registers Diagram

7.8.2 Conditional registers

The fault Condition Register and the Status Condition Register are read only registers that the user may read to see the condition of the supply. Refer to table 7-8 for description of the Fault Condition Register bits and Table 7-9 for the Status Condition register bits.

SRQ = “!nn”, nn = address

7.8.2 Conditional registers

7.8.3 Service Request: Enable and Event Registers

The conditional Registers are continuously monitored. When a change is detected in a register bit which is enabled, the power supply will generate an SRQ message. The SRQ message is: "!nn" terminated by CR, where the nn is the power supply address. The SRQ will be generated either in Local or Remote mode.

CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION

8.1 INTRODUCTION

Isolated Analog Programming is an internal option card for analog programming of the Genesys power supply series. The option is factory installed and cannot be obtained with GPIB (IEEE) Interface. Output Voltage and Current Limit can be programmed and readback through optically isolated signals which are isolated from all other ground references in the power supply. There are two types of Isolated Analog programming cards:

1. 0-5V/0-10V option (PN: IS510): Using 0-5V or 0-10V signals for programming and readback.

2. 4-20mA option (PN: IS420): Using current signals for programming and readback.

NOTE:

Use 100Kohm minimum input impedance for the monitoring circuits to minimize the readback error.
