NOTE
The parameters for this control are grouped together in blocks to permit navigation through the large
number of configuration screens more rapidly. Selecting "YES" or "NO" has no effect whether or not
control or monitoring is carried out for the parameters located in that block. Selecting "YES" or "NO"
only determines if the individual parameters may be accessed and changed or are bypassed.
Parameter 139
Configure
monitoring YES
Configuration of the protection YES/NO
The generator and system protective functions are configured in this block of pa-
rameters. This parameter has the following effects:
YES .............. The parameters in this block are displayed and can either be viewed
("Select" button), or modifications can be made to the parameters
("Cursor→", "Digit↑" or "Select" buttons).
NO ................ The parameters in this block are not displayed, cannot be modified,
and are skipped.
Generator Power Monitoring
It is possible for the GCP to monitor two independently configured generator power limits. If one of these confi-
gured limits is surpassed, it is possible to energize a relay output by assigning a relay manager function (relay
manager function 56 and 80) to one of the freely configurable relays. This functionality makes it possible to in-
itiate external load shedding.
NOTE
This functionality does not initiate a centralized alarm or issue a message to be displayed. An external
device must evaluate the relay output.
WARNING
This function does not provide generator protection.
Parameter 151 and Parameter 156 or an external protection device must be used if generator protection
is
required.
Parameter 140
Gen.power monit.
ON
Generator power monitoring ON/OFF
ON ................ Generator power monitoring is enabled. Relay manager function 56
must be assigned to one relay and relay manager function 80 must be
assigned to a second relay. The subsequent screens of this function
are displayed.
OFF .............. Generator power monitoring is disabled. The subsequent screens of
this function are not displayed.
