4.3.4 Remote Programming Only the Output Voltage or Current Limit
The front panel REMOTE/LOCAL switch allows you to switch back and forth between remote
and local programming signals for all three programming inputs of Voltage, Current, and OVP.
When operation is desired for programming only the output voltage and/or current limit without
the other, or to leave the OVP control on the front panel, follow the procedures below:
Remote Programming of the Output Voltage Only
For remote programming of output voltage only:
1. Turn off power to the supply.
2. Connect a programming source to remote programming connector J3 between pins 9
(voltage programming input/positive) and 12 (return).
3. Connect a jumper between remote programming connector pins J3-20 and J3-21 for
external control of output voltage.
4. Adjust the external programming signal to zero.
5. Switch the ENABLE/STANDBY switch to STANDBY.
6. Turn the power supply ON.
7. Set the front panel LOCAL/REMOTE switch to the LOCAL position and adjust the
external programming signal. By pressing the V&I PREVIEW button and observing the
front panel voltmeter reading, the external control can be adjusted to the desired setting.
8. Adjust the current and OVP controls to the desired settings with the front panel controls
9. Switch the ENABLE/STANDBY switch to ENABLE.
10. The output voltage is now remotely programmed with local control of the current limit
and OVP settings.
