You can customize remote operation settings for OVP (over voltage
protection) control and TTL shutdown by changing jumper positions on
the

information on how to use over voltage protection and TTL shutdown.
Over voltage protection (OVP) on the
the factory for 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 REN software command or the front panel LOCAL switch,
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
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 J65 and the Remote OVP Control jumper
J103, both on the
Ethernet/RS-232 Interface
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.
