Protection Delay
You can specify an OCP/OVP/OPP/UCP/UVP delay to prevent momentary out-
put settings and status changes from tripping the protection. In most cases
these momentary conditions would not be considered an protection fault, and
having an OCP/OVP/OPP/UCP/UVP condition disable the output when they oc-
cur would be a nuisance. Specifying an protection delay (Delay) can ignore
these momentary changes during the specified delay period. Once the delay
time has expired and the protection limit condition persists, the output will shut
down.
