Output Purpose Description Label
True False
VOA Relay Trouble alarm.
OUTA contact closes when relay
trouble alarm occurs.
RELAY-TROU ACTIVE NORMAL
BESTlogic Expression: VOA=0
VO1
Phase differential trip.
OUT1 is a high-speed trip
contact. OUT1 contact closes if a
restrained, unrestrained, or time
overcurrent trip occurs.
