CAUTION

If you remove the unit's cover, use proper static control techniques to avoid damage to static-sensitive components on the printed circuit board.

You can customize remote operation settings for OVP (over voltage protection) control and TTL shutdown by changing jumper positions on the RS-232 PCB. Refer to the operating manual for information on how to use over voltage protection and TTL shutdown.

OVP Over voltage protection (OVP) on the RS-232 interface is set at the factory for Selection remote software operation. When operating the power supply in remote mode, you

control the OVP trip level using the OVSET software command. If you return the power supply to local operation by using the REM software command, control of the OVP trip level changes from software control to the front panel OVP potentiometer. The default OVP trip level is set as 110% of the power supply's rated output voltage. See Table 2.10, on page 24 for a complete list of remote power ON default settings.

You can isolate the location of OVP control by changing the positions of the Local OVP Control jumper J2 and the Remote OVP Control jumper J20, both on the RS-232 interface PCB. The default jumper settings allow control of OVP to depend on the operating state of the power supply. By physically changing the jumper settings, you can isolate the location of OVP control to software control only or front panel control only. Table 2.12, “OVP Control Mode Selection” shows a table of jumper settings and OVP programming selection. Refer to “Basic Setup Procedure” on page 19 for the positions of the jumpers on the RS-232 PCB.
