8.5.1

Setting Up The Master Unit

Setting up the Power Supply for 0-5/0-10V Isolated Programming and Monitoring.
Perform the following procedure to configure the power supply:
1. Press the power supply AC Input power switch to the OFF position.
2. Connect a wire jumper between J1-8 and J1-12 (refer to Table 4-4).
3. Set DIP-switch SW1-1 to the UP position for Output voltage external programming and SW1-2 to
the UP position for Output current limit external programming.
4. Set SW1-3 to select the Programming Voltage Range: DOWN = 0-5V, UP = 0-10V.
5. Set SW1-4 to select the Monitoring Voltage Range: DOWN = 0-5V, UP = 0-10V.
6. Ensure that SW1-7 and SW1-8 are in the DOWN position.
7. Connect the programming sources to the mating plug of the Master Isolated Programming
connector. Observe for correct polarity of the voltage source.
8.5.2

Setting Up The Slave Unit

Setting up the Power Supply for 0-5/0-10V Isolated Programming and Monitoring.
Perform the following procedure to configure the power supply:
1. Press the power supply AC Input power switch to the OFF position.
2. Connect a wire jumper between J1-8 and J1-12 (refer to Table 4-4).
3. Set DIP-switch SW1-1 to the DOWN position for Output Voltage programming by front panel and
SW1-2 to the UP position for Output Current limit external programming.
4. Set SW1-3 to select the Programming Voltage Range: DOWN = 0-5V, UP = 0-10V.
5. Set SW1-4 to select the Monitoring Voltage Range: DOWN = 0-5V, UP = 0-10V.
6. Ensure that SW1-7 and SW1-8 are in the DOWN position.
7. Connect pin 7 (IMON_ISO) of the Master unit Isolated Analog connector to pin 3 (IPROG_ISO) of
the Slave unit Isolated Analog connector.
8. Connect pin 4 (GND) of the Master unit Isolated Analog connector to pin 4 (GND) of the Slave unit
Isolated Analog connector.
Daisy-Chain Connection:
NOTE: All power supplies should be connected
in a daisy-chain configuration
9. Connect J1-2, -3 of the Master unit to J1-2, -
3 of the Slave unit.
10. Connect J1-15 of the Master unit to J1-16 of
the Slave unit.
11. Connect J1-16 of the Master unit to J1-15 of
the Slave unit.
12. Set the Master unit programming sources to
the desired programming levels.
13. Turn ON the Master and Slave power
supplies by pressing their respective AC Input power switch to the ON position and then pressing
the Master unit front panel display OUT button.
14. Check and readjust the Master unit programming sources to the desired programming levels.
CAUTION
Output current to higher then the power supply ratings.
