Generator Overload Monitoring
NOTE
All percentage values refer to a percentage of the generator rated power (Parameter 32; page 26).
Function: "Positive real power not within the permissible range" - The single-phase or three-phase measured ge-
nerator real power is above the configured limit value of the real power.
Parameter 178
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 179
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 180), the following alarm class is initiated
(MOP ..Mains Parallel Operation).
Issuing of class F2 alarm
without power reduction
Parameter 180
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 179 must be exceeded without inter-
rupt
ion for this period of time (
MOP ..Mains Parallel Operation).
Parameter 181
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 182), the following alarm class is initiated
(IOP ..Isolated Parallel Operation).
Issuing of class F2 alarm
without power reduction
Parameter 182
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 181 must be exceeded without inter-
rupt
ion for this period of time (
IOP ..Isolated Parallel Operation).
