The protective functions are divided into 4 failure modes:
F0:
Warning. Gives warning only, no interference with the present running situation.
F1:
As F0, but with setting of alarm output : Common failure.
F2:
Stop. Trips breaker and stops genset after cooling down time.
F3:
Shutdown. Trips breaker and stops genset immediately.
By activation of "shutdown inhibit mode" (terminal 6), functions F2 and
F3 are changed to F1 (shutdown blocking)!!!

DESCRIPTION
ON/OFF. ON: Running parallel with
mains, the power factor will be kept
at preset value, regardless of
power consumption. By very low
loads (secondary current <5% I n ),
the control can become unstable.
Therefore, in this case, the control-
ler is overruled.
1...i 0.70 (i = inductive) The reac-
tive power is controlled in such a
manner, that the preset power
factor value is kept constant.
0.5...25.5%. Neutral zone, power
factor controller, percentage of ge-
nerator nominal power. The MGC-1
calculates the reactive power value
necessary to reach the desired
power factor. In parallel with mains,
the reactive power will be within
(P nom. ±Nz)*cos .
1.0...99.9. Amplification factor,
power factor controller. The Kp af-
fects the ON time for the relay out-
put. Kp
= ON time
