CF03 Method for Clearing OHP, FAN, and AC-FAIL Alarms
Sets the method for clearing alarms when overheat protection (OHP), fan failure protection
(FAN), or low AC input protection (AC-FAIL) has been activated. You cannot set this parameter
separately for each protection function.
When you select "Auto," if the overheat protection function (OHP) has been activated, output
will turn on again automatically when the internal temperature drops to a normal level. However,
if you do not fix the problem that caused the alarm to occur, the alarm will occur again, which
will force you to clear the alarm again. The overheat protection devices have long service lives
(approximately 100000 uses), but if they reach the end of their service lives, they will stop
operating. To maintain the performance of the RMX programmable power supply for a long
time, we request that you fully understand the Auto feature and only use it when necessary.

the panel settings are reset (CF00) and when a preset memory entry is recalled.
You can only specify this parameter when the RMX programmable power supply is being used
as a master unit.
