3.3 INITIAL INSPECTION
Prior to shipment this power supply was inspected and found free of mechanical or electrical
defects. Upon unpacking of the power supply, inspect for any damage which may have occured in
transit.
The inspection should confirm that there is no exterior damage to the power supply such as broken
knobs or connectors and that the front panel and meters face are not scratched or cracked. Keep all
packing material until the inspection has been completed. If damage is detected, file a claim with
carrier immediately and notify the Lambda sales or service facility nearest you.

WARNING
Some components inside the power supply are at AC voltage even when the On/Off switch is in the
“Off ” position. To avoid electric shock hazard, disconnect the line cord and load and wait two
minutes before removing cover.
CAUTION
AC Input 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.
The power supply ON/OFF switch is not the main “disconnect device” and does not completely
disconnect all the circuits from the AC source.
An appropriately rated “disconnect device” such as circuit breaker, type B plug on power cord, ...etc.,
shall be provided in the final installation. The “disconnect device” for one phase units shall
disconnect both supply lines simultaneously. The “disconnected device” must be easily accessible.

3.9 CONNECTING THE LOAD
WARNING
Turn off the AC input power before making or changing any
rear panel connection. Ensure that all connections are
securely tightened before applying power. There is a potential
shock hazard when using a power supply with a rated output
greater than 40V.
3.9.1 Load Wiring
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).
3.9.2 Current Carrying Capacity
Two factors must be considered when selecting the wire size:
1. Wires should be at least 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.
18
18
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 voltage drop in American and European
dimensions respectively.

where current is expressed in Amperes and resistivity in ohms/km or ohms/1000ft.
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.
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.)
19
19
3.9.4 Noise and Impedance Effects
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 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.
3.9.5 Inductive loads
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.
3.9.6 Making the load connections
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.
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.
8V to 100V Models
Refer to Fig.3-6 for connection of the load wires to the power supply bus-bars and to Fig.3-7

maximum output voltage of the power supply.
CAUTION
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.

The 150V to 600V models have a four terminal wire clamp output connector:
Phoenix Contact P/N: FRONT4-H-7.62/4
The two left terminals are the positive outputs and the other two right terminals are the negative
outputs.Max. 30A per terminal.
The connector requirements are as follows:
1. Wires: AWG18 to AWG10.
2. Tightening torque: 4.4-5.3Lb-inch. (0.5-0.6Nm).
Follow the below instructions for connection of the load wires to the power supply:

3.9.11 Grounding 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.3-15 for sense connector location.
3.10.1 Sense wiring
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 accidental contact 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.

3.10.3 Remote sensing
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.
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.
Notes:
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 5 LOCAL OPERATION
5.1 INTRODUCTION
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.
5.2 STANDARD OPERATION
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.
5.2.1 Constant Voltage Mode
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 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.
NOTE
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.
NOTE
The maximum and minimum setting values of the output voltage are
limited by the Over Voltage protection and Under Voltage limit setting.
Refer to Sec.5.3 and 5.4 for more details.
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 VOLTAGE meter will display "OFF".
34
34
- 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.
5.2.3 Automatic Crossover
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.
5.3 OVER VOLTAGE PROTECTION (OVP)
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.
5.3.1 Setting the OVP level
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 Table 5-1.
Model
To preview the OVP setting, press OVP/UVL
pushbutton so that the CURRENT display will show
"OUP". At this time, the VOLTAGE display will show the
OVP setting. After 5 seconds, the display will return to
it's previous state.

5.3.2 Activated OVP protection indications
When the OVP is activated the power supply output shuts down. The VOLTAGE display shows
"OUP" and the ALARM LED blinks.
5.3.3 Resetting the OVP circuit
To reset the OVP circuit after it 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 OVP circuit.
3.1 Press OUT button.
3.2 Turn the power supply Off using the AC On/Off switch, wait until the front panel display turns
Off, then turn the power supply On using the AC On/Off switch.
3.3 Turn the power supply output Off and 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.
35
35
5.4 UNDER VOLTAGE LIMIT (UVL)
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.
5.4.1 Setting the UVL level
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.
5.5 FOLDBACK PROTECTION
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.
5.5.1 Setting the Foldback protection
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.
5.5.2 Resetting activated Foldback protection
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.
5.6 OUTPUT ON/OFF CONTROL
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”.
5.7 OUTPUT SHUT-OFF (SO) CONTROL VIA REAR PANEL J1 CONNECTOR
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 , in Auto-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.
36
36
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.

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.
5.9 CV/CC 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.
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.
5.10 PS_OK SIGNAL
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:
*OTP
*OVP
*Foldback
*AC fail
*Enable/Disable open (Power supply is disabled)
*SO (Rear panel Shut-Off - Power supply is shut off))
*IEEE failure (with optional IEEE interface)
*Output Off
37
37
5.11 SAFE START AND AUTO-RESTART MODES
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.
5.11.1 Automatic start 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.
5.11.2 Safe start mode
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 OUT button.
5.12 OVER TEMPERATURE PROTECTION (OTP)
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.
1. Safe start 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 the ALARM LED
continues to blink. To reset the OTP circuit, press OUT button (or send OUT ON command via the
serial port).
2. Auto-restart mode: In Auto-restart mode , the power supply recovers to it's last setting
automatically when the over temperature condition is removed.
5.13 LAST SETTING MEMORY

5.14 SERIES OPERATION
Power supplies of the SAME MODEL can be connected in series to obtain increased output voltage.
Split connection of the power supplies gives positive and negative output voltage.
38
38
CAUTION
Do not connect power supplies from different
manufacturers in series or in parallel.
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.
WARNING
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

In this mode, two units are configured as a positive and negative output. 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 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.5-3 for this operating mode.

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.
5.15.1 Basic parallel operation
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.
1. Setting up the Master unit
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.
2. Setting up the slave units
-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.
-6. Connect J1 terminal 23(IPGM_RTN) of the slave unit to J1 terminal 12(COM) 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.
3. Setting Over Voltage protection
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.
4. Setting Foldback protection
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.
5. Connection to the load
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
5.15.2 Advanced parallel operation
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.
1. Basic configuration
Repeat steps 1 to 5 in Sec. 5.15.1 (Basic parallel operation).

2. Setting the units as Master or Slave
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.

Table 5-4: Setting mode of operation
b) When the desired configuration is obtained, depress and release the FINE button or wait
approx. 5 seconds.
3. Master and Slave units default operation
a) When a unit is programmed to Slave mode it enters the Remote mode with Local Lockout. In
this mode, the front panel controls are disabled to prevent accidental setting change (refer to Sec.
7.2.7 for details).
b) The Slave units parameters will automatically set the following:
*AST On
*Output voltage to approximate. 102% of rated output voltage.
*OUT On
*Programmed Current to zero.
*Foldback protection Off
*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.
4. CURRENT display accuracy
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.
5. To release units from Slave 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:
*Programmed Voltage to zero
*AST OFF
*Programmed Current to zero
*OUT OFF
*UVL to zero volts
*Foldback protection OFF
*OVP to its maximum value
*Locked Front Panel

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.

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
are referenced to the -Vout potential (-V). Do not connect these terminals to
any potential other than -Vout (-V), as it may damage the power supply.
6.2 LOCAL /REMOTE ANALOG CONTROL
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.

6.4 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT
CAUTION
To maintain the isolation of power supply and prevent ground loops, use an
isolated programming source when operating the power supply via remote
analog programming at J1 connector.
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.
NOTES:
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.

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, J1-12 and J1-23 (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.
NOTES:
1. SW1 positions 4, 5, 6 and 9 are not required for remote programming. Their setting can be
determined according to the application requirements.
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.
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.

The backslash character “\” will cause the last command to be repeated.
7.5.5 Checksum
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
7.5.6 Acknowledge
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.

CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION
8.1 INTRODUCTION
TM
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.
