12. 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

b)Preset “b”in “out”mode
•”PL” is shown during “dt” in case initial line phase state is phase loss, consequently main trip
output(97-98) is trip right after “dt”is elapsed
•Main trip output(97-98) is trip after the sum of “dt”and operational 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
▸”rotA”Mode : OFF →voltage of L1, L2, L3
▸”rotA”mode: ON →voltage of L1,L2,L3, Frequency

▸Average voltage : same as a case of line voltage by “rotA”ON,OFF
▸Bar graph indication : DSP-DVR-M Type
Operational state
The ratio of a sensed voltage to preset “ov”value is shown
e.g. preset value for “ov”:400V, sensed voltage :320V, then bar graph:80%
Trip state

13.Time-Voltage based trip output
▸Over Voltage : “out”mode/a, trip caused by over-voltage during a normal operation
▸Over Voltage : “out”mode/b, trip caused by over-voltage during a normal operation

▸Over/Under voltage: “out”mode/a, auto reset after trip during a normal operation
▸Over/Under voltage: “out”mode/b, auto reset after trip during a normal operation
