Generator Frequency Monitoring
Function: "Generator frequency not within the permissible range" - The generator frequency is outside of the
limit values set for overfrequency or underfrequency. The engine is shut down immediately (class F3 alarm), and
an alarm message is displayed. The activation of generator underfrequency monitoring is delayed by means of
"Delayed engine monitoring" (Parameter 307) in order to enable correct generator start-up.
Parameter 195
Gen.frequency-
monitoring ON
Generator frequency monitoring ON/OFF
ON ................ Monitoring of the generator frequency will be performed. The subse-
quent parameters of this function are displayed.
OFF .............. Monitoring is disabled, and the subsequent screens of this function
are not displayed.
Parameter 196
Gen.overfreq.
f > 000.0%
Threshold value: generator overfrequency 50.0 to 140.0 %
L This value refers to the parameter "Rated freq. in system" (Parameter 11).
If this threshold value has been exceeded for at least delay time (Parameter 197),
th
e following alarm class is initiated.
Issuing of class F3 alarm
Parameter 197
Gen.overfreq.
delay 0.00s
Generator overfrequency delay 0.02 to 9.98 s
For the control unit to recognize a generator overfrequency fault condition, the
threshold value configured in Parameter 196 must be exceeded without interruption
for t
his period of time.
Parameter 198
Gen.underfreq.
f < 000.0%
Generator underfrequency threshold value 50.0 to 140.0 %
L This value refers to the parameter "Rated freq. in system" (Parameter 11).
If the current value has been fallen below this threshold value for at least the delay
time (Parameter 199), the following alarm class is initiated.
Issuing of class F3 alarm
Parameter 199
Gen.underfreq.
delay 0.00s
Generator underfrequency delay 0.02 to 9.98 s
For the control unit to recognize a generator underfrequency fault condition, the
threshold value configured in Parameter 198 must be exceeded without interruption
for t
his period of time.
Engine Overspeed Monitoring
Parameter 200
Engine overspeed
> 0000 rpm
Engine overspeed monitoring 0 to 9,999 rpm
The overspeed monitoring is performed in addition to and independent of the gene-
rator frequency if the Magnetic Pickup Unit (MPU) has been enabled (Para-
m
eter 309). If the MPU has been disabled, the monitoring is disabled. If this thre-
shold value is been exceeded the following alarm class is initiated.
