Rotated indication
▸
If line voltage value with normal phase order is sensed after the control power is loaded, then 3
phase line voltage indication is rotated
▸
output(95-98) is energized (Open→Close) as normal phase voltage is loaded if out” mode is
preset “a”
▸
output(95-98) is not energized (Open→Open) if out” mode is preset “b”
▸
however v.oFF is shown if the voltage is not sensed or the voltage is dropped into 0V(Zero Volt)
while normal operation is done
▸
If single phase is applied. V-OFF or actual voltage is shown
▸
”dt”(trip delay time) mode is preset “OFF”
a)Preset “a” in “out” mode
•
Main trip output(97-98) is trip at once in case initial line phase state is phase loss
•
Main trip is energized ,then is trip after operational trip time is elapsed in case initial line phase
state is under reverse phase,over/under voltaege and voltage unbalance as each mode is preset
valued condition,also trip cause is shown
