The J1 connector also provides monitoring signals for the output

 

voltage and output current. The programming range and monitoring

 

signal range can be selected using the SW1 setup switch.

 

With analog programming enabled, you cannot program the output voltage or

current using the front panel knobs or the remote interface. However, you can

 

read back output voltage or current from the front panel or the remote interface.

 

 

Analog Programming Control Terminals

J1 connector pin 8 accepts a TTL signal or an open/short contact switch (referenced to pin 12) to select between Local or Analog programming of the output voltage and current. This function is enabled or disabled by SW1 setup switches 1 and 2.

J1 connector pin 21 is an open collector output that indicates if the power supply is in Local mode or in Analog mode. To use this output, connect a pull-up resistor to a voltage source of 30 VDC maximum. Choose the pull-up resistor so that the sink current will be less than 5mA when the output is in low state.

isolated programming source when operating the unit using analog programming.

Voltage programming sources of 0 - 5 V or 0 - 10 V can be used to program the output voltage and current limit from zero to full scale.

Set the power supply to analog voltage programming as follows:

Make sure that the power supply is turned off.

Set SW1 setup switch 1 (for voltage) and 2 (for current) to the Up position.

Set SW1 setup switch 3 to select programming voltage range according to the following table.

Make sure that SW1 setup switches 7 and 8 are set Down.

Connect a short between J1 pin 8 and J1 pin 12 (see figure).

Connect the programming source to the mating plug of J1 as shown in the following figure. Observe the correct polarity for the voltage source.
