Deactivates in the moment when the measured values are back in limits. Fault reset has no effect on
this output.
I Unb Sig
Signalling of current unbalance according to the setting in I Unb group. Activates immediately in the
moment of fault conditions (does not wait until delay times out). Deactivates in the moment when the
measured values are back in limits. Fault reset has no effect on this output.
DOC Sig
Signalling of directional overcurrent protection. Activates immediately in the moment of fault conditions
(does not wait until delay times out). Deactivates in the moment when the measured values are back
in limits. Fault reset has no effect on this output.
DOC Test
Test output for directional overcurrent protection. When the setpoint DOC Test is set to ENABLED, the
directional overcurrent protection activates this output even if standard activating conditions are not
fulfilled. This is to allow full quadrant range test of this protection
–
this output stays active all the time
the protection senses the corresponding quadrant and magnitude of the current.
Activating DOC test
does blocks the regular function of the ANSI 67 directional overcurrent protection stage!
EFC >Sig
Signalling of earth fault over current condition according the setting in EFC group. Activates
immediately in the moment of fault conditions (does not wait until delay times out). Deactivates in the
moment when the measured values are back in limits. Fault reset has no effect on this output.
IGS > Sig
Signalling of ground surge protection according the setting in IGS group. Activates immediately in the
moment of fault conditions (does not wait until delay times out). Deactivates in the moment when the
measured values are back in limits. Fault reset has no effect on this output.
NVD Sig
Signalling of neutral voltage displacement conditions according the setting in NVD group. Activates
immediately in the moment of fault conditions (does not wait until delay times out). Deactivates in the
moment when the measured values are back in limits. Fault reset has no effect on this output.
P Sig
Signalling of out off limit power according the setting in P<> group. Activates immediately in the
moment of fault conditions (does not wait until delay times out). Deactivates in the moment when the
measured values are back in limits. Fault reset has no effect on this output.
Sync Check
Binary output related to ANSI 25 Synchro check. The output is active in either of the following cases:
-
voltage, frequency and phase condition are met and dwell time is over according to the setting
in Sync Check group
-
connection to dead line or bus are enabled and the voltage is under Dead Voltage limit for the
dwell time
AC Reclosing
Binary output related to ANSI 79 AC Reclosing. The output closes AR Delay after power-up of the unit.
The output opens immediately when the appropriate trip event appears. The trip, which is considered
for the reclosing function is selected by the setpoint AC Reclosing: Rec Initiate. The output closes
again with the pre-set delay after the trip state terminates.
