Parameter 137
Configure
monitoring YES
Configuration of the protection YES/NO
Parameters are grouped together in blocks to permit quicker navigation through the
large number of configuration screens. Selecting "YES" or "NO" has no effect if
controlling or monitoring is performed. This parameter has the following effects:
YES ..............The configuration screens in the next block are displayed and can ei-
ther be viewed ("Select" push-button) or modified ("Cursor →",
"Digit ↑" or "Select" push-buttons).
NO................The parameters in the next block are not displayed, cannot be modi-
fied and are therefore skipped.
Generator Power Monitoring
It is possible to monitor a configurable generator power limit value. It is possible to output the tripping to one of
these freely configurable relays by means of the relay manager (relay manager function 56). This function makes
it possible to initiate external load shedding.
NOTE
With this function no centralized alarm is issued and no message is displayed. A relay output is en-
abled which must be externally evaluated.
WARNING
This function does not operate as generator protection.
If generator protection is necessary, either the generator protection of this control (Parameter 146 and
Parameter 151) or an external protection device should be used.
Parameter 138
Gen.power monit.
ON
Generator power monitoring ON/OFF
ON................The generator power is monitored (relay manager function 56 must
be assigned to a relay). The subsequent screens of this function are
displayed.
OFF..............Monitoring is not carried out, and the subsequent screens of this
function are not displayed.
Parameter 139
Power monitoring
resp.value 000%
Generator power monitoring threshold value 0 to 150 %
If this threshold value has been exceeded for at least the delay time (Para-
meter 141), the relay assigned relay manager function 56 energizes.
Parameter 140
Power monitoring
gen.hyst. 000%
Generator power monitoring hysteresis 0 to 99 %
If the monitored generator power level drops below the threshold value configured
in
Parameter 139 by value configured here, hysteresis occurs and the relay de-
energizes.
Parameter 141
Power monitoring
Delay time 000s
Generator power monitoring delay 0 to 650 s
For the control unit to recognize a power monitoring fault condition, the threshold
value configured in
Parameter 139 must be exceeded without interruption for this
period of time.
