%
Range:
Gen<f
– 150,0 % of
Nominal freq
Protection:
BreakerOpen & Cool-down.
Gen <f

Gen>f
% of
Nominal freq
Protection:
BreakerOpen & Cool-down.
Hint:
The generator frequency is evaluated from the L3 phase.
Gen f del

0,00 – 600,00 s
BusMeasError
[ DISABLED / ENABLED ] (FV)
DISABLED:
The protection is off.
ENABLED:
Bus measure error is detected in MINT / COX application when the voltage on controller‘s
bus terminals is out of limits 20 seconds after:
a) GCB (own) was closed in MAN or AUT mode.
b) MCB (feedback) was closed in AUT mode.
c) Any other GCB in power management group (on CAN bus) was closed. The alarm is activated after
20 s, however the GCB (own) closing is blocked immediately from safety reasons.
Force value possibility: Yes
Protection:
BreakerOpen & Cool-down.
Reverse power
[ % ]
Threshold for generator reverse (back) power alarm in % of nominal power.
Step:
1
%
Range:
0 – 50 % of
Nomin power
Protection:
BreakerOpen & Cool-down.
ReversePwr del
[ s ]
Delay for generator back (reverse) power alarm.
Step:
0,1 s
Range:
0 – 600,0 s
Range:
-32000 – 0 kW
EarthFaultCurr
[ A ]
Threshold for generator Earth fault current protection. The value is measured via the 4
th
current terminal In /
Im3.
Step:
1 A
Range:
0 – 10000 A
Protection:
BreakerOpen & Cool-down.
EthFltCurr del
[ s ]
Delay for generator Earth fault current protection.
