Checking the OVP or OCP operation
The OVP or OCP is a function for protecting the load. Once you set the OVP or
OCP trip point, check that the OVP or OCP works before you connect the load by
carrying out the procedure below.
If the voltage limit setting is enabled in the CONFIG settings (CF29: ON), the
output voltage cannot be set higher than the OVP trip point. Thus, you will not be
able to check the OVP operation.
If the current setting limit is enabled in the CONFIG settings (CF30: ON), the
output current cannot be set higher than the OCP trip point. Thus, you will not be
able to check the OCP operation.

When the setting value of output voltage exceeds OVP trip point, the ALARM LED on
the front panel display illuminates and either of the POWER switch or the output will
be turned off (Depending on the CONFIG settings).
When the POWER switch is turned off, the ALARM LED illuminates even the power
turns off, and the Power-off display of the over voltage protection (OVP) will be
displayed for about 10 to 15 seconds. When the output is turned off, OVP function
display and the measuring value are displayed alternately and the ALARM LED
continues to be illuminated.
