WARNING
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 effectsof the load wiring (refer to 3.9.4).
Two factors 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 consum- ption 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 voltage drop in American and European dimensions respectively.

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 twisted­pairs 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 viaarear panel Ground screw. Even if noise is notaconcern, 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.Adiode 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 fromamotor 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 shield 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.

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 apair 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 twowires to connect the load to the power supply regardless of how the system is grounded.
WARNING

WARNING
There isapotential 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 voltage regulation will be degraded. Also, the OVP circuit may activate and shut down the power supply.

CHAPTER 5LOCAL 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 voltage at the selected value, while the load current varies as required by the load.
2. While the power supply operates in constant voltage mode, the VOLTAGELED 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 VOLTAGEmeter will show the programmed output voltage for5seconds after the adjustment has been completed. Then the VOLTAGEmeter 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 VoltageMode
If after completing the adjustment, the display shows a different value than the setting, the power supply maybeat 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
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 CURRENT LED 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 VOLTAGEmeter 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 for5seconds 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 Voltagemode, 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 ofaremote or local programming error orapower 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 VOLTAGEmeter shows the OVP setting level. Rotate the VOLTAGE encoder knob to adjust the OVP level. The display will show "OUP" and the setting value for5seconds 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 Table 5-1.

5.5 FOLDBACKPROTECTION
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 FOLDLED 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 LEDtoblink 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 OUT button 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 Off using 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.
TheOutput 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 timeto 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 Offis 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 ina“Daisy-chain” (refer to section 5.16). TheSO control can be used also to reset the OVP
and Fold Protection. Refer to sect. 5.3 and 5.5 for details.

When the unit is shut-offbyJ1 signal, the VOLTAGE display will show “SO” to indicate the unit state. J1 contact 15 is the SO signal input and contacts2and 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 St art mode-If the Enable/Disable fault condition clears when unitsin 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 inputsto the positive or negative output potential.
CAUTION
Do not connect CV/CC signal toavoltage 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.

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 status readback only.
There are two methods, basic and advanced, to configure multiple supplies for parallel operation. With both methods, Power Supplies, should be connected in a Daisy-Chain configuration.
Refer to Sec. 5.15.1 , to Sec. 5.15.2 and to Sec.5.16 for detailed explanation.
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.

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 amultiple power supply system to shut down all the unitswhen 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 itsDown position to enable the Daisy-chain operation. Other SW1 positions can be set according to the application requirements. Ifafault occurs in one of the unitsits PS_OK signal will be set to low level and the display will indicate
the fault. The other unitswill shut off and their display will indicate "SO”. When the fault condition is
removed, the unitswill recover to their last setting according to their Safe start orAuto-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 /REMOTEANALOG CONTROL
Contact 8ofJ1 (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 programmedby 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/REMOTEANALOGINDICATION
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 toavoltage 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 to Table 6-2 for J1-21 function.

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 asaprogramming 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, oracombination 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:

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 MONITORINGOF OUTPUTVOLTAGE 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 0to 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.

7.7.6 Global output commands
1. General
All supplies, even if not the currently addressed supply, receivingaglobal command will execute the command. No response to the PC issuing the command will be returned to the PC. The PC issuing the command will be responsible to delay and any other communications until the command is execute. 200 Ms minimum is the suggested delay.
If the command contains an error, out of range values for example, no error report will be sent to the issuing PC.
Reset. Brings the Power Supply toasafe and known state: Output voltage: 0V, output current: 0A, OUT:Off, Remote: RMT 1’ AST:Off OVP:Max, UVL:0. The conditional register (FLT and STAT) are updated. Other registers are not changed. Non-Latching faults (FB, OVP, SO) are cleared, OUT fault stays.
Sets the output voltage value in volts. The range of voltage values is shown in Table 7-3. ‘n’ may be up to 12 char plus dec. pt
Program the output current value in amperes. The range of current values is shown in Table 7-4. ‘n’ may be up to 12 char plus dec. pt
Turns the output to ON or OFF: “OUT 1/ON”=turn on “OUT 0/OFF”= turn off, clears CV and CC bitsin the Status Condition (STAT) OUT ON will respond with “E07’if the output cannot be turned on because ofalatching fault (OTP< AC, ENA, SO) shutdown.

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 circuitsto minimize the readback error.
