Generator Overload Monitoring
NOTE
All percentage values refer to a percentage of the generator rated power (Parameter 17; page 75).
Function: "Positive real power not within the permissible range" - The single-phase or three-phase measured
generator real power is above the configured limit value of the real power.
Parameter 146
Overload monit.
ON
Generator overload monitoring ON/OFF
ON................Monitoring of the generator real power will be performed. The sub-
sequent parameters of this function are displayed.
OFF..............Monitoring is disabled, and the subsequent screens of this function
are not displayed.
Parameter 147
Gen.overload MOP
resp.value 000%
Generator overload monitoring threshold value MOP 80 to 150 %
If this threshold value has been exceeded for at least the delay time (Para-
meter 148), the following alarm class is initiated
(MOP = Mains Parallel Operation).
Issuing of class F2 alarm
without power reduction
Parameter 148
Gen.overload MOP
delay 00s
Generator overload monitoring delay 0 to 99 s
For the control unit to recognize a generator overload monitoring fault condition,
the threshold value configured in
Parameter 147 must be exceeded without inter-
ruption for this period of time (
MOP = Mains Parallel Operation).
Synchronous Generators
Parameter 149
Gen.overload IOP
resp.value 000%
Generator overload monitoring threshold value IOP 80 to 150 %
If this threshold value has been exceeded for at least the delay time (Para-
meter 150), the following alarm class is initiated
(IOP = Isolated Parallel Operation).
Issuing of class F2 alarm
without power reduction
Parameter 150
Gen.overload IOP
delay 00s
Generator overload monitoring delay 0 to 99 s
For the control unit to recognize a generator overload monitoring fault condition,
the threshold value configured in
Parameter 149 must be exceeded without inter-
ruption for this period of time
(IOP = Isolated Parallel Operation).
