Gen <f [ Hz ]
Threshold for generator under frequency.
Step: 0,1 Hz
Range: 40,0 – 70,0 Hz
Protection: BreakerOpen & Cool-down.
Hint:
The generator frequency is evaluated from the L3 phase.
Gen f del [ s ]
Delay for generator under frequency and over frequency protection.
Step: 0,02 s
Range: 0,00 – 600,00 s
Min stab time
This is the minimum time the controller will wait, after switching the engine to nominal RPM, to close the
GCB (the delay ensures that the GCB is closed with correct generator frequency/voltage).
Step: 1s
Range: 1 – Max stab time s
Force value: Yes
Max stab time
This is the maximum time the controller will wait for generator voltage and frequency to build up, after
switching the engine to nominal RPM.
Step: 1s
Range: Min stab time – 3600 s
Force value: Yes
Hint:
When generator voltage in Max stab time does not reach defined limits (see Gener protect group), an alarm
occurs and the gen-set will cool down and stop.
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: Yes
Reverse power [ kW ]
Threshold for generator reverse (back) power alarm.
Step: 1 kW
Range: -60000 – 0 kW
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
