1604 Force 3PTrip CB2 PSL
External input via DDB to force host relay trip
conversion logic to issue a three phase trip
signal to CB2 for all faults
P544 and P546 only
1605 Enable AR CB2
External input via DDB to enable CB2, if "in
service", to be initiated for autoreclosing by an
AR initiation signal from protection. DDB input
defaults to high if not mapped in PSL, so CB2
AR initiation is permitted.
