IGS-NT Combi, SW Version 3.0, ©ComAp – May 2013
IGS-NT-Combi-3.0 Reference Guide.PDF
Speed dn is used (i.e. at least one of these outputs is configured onto a physical
or virtual output terminal).
Alarm output: WrnVoltRegLim
This output is closed while the WrnVoltRegLim alarm is present in the alarm list,
i.e. while the analog output for AVR is near minimum or maximum position (out of
the range 2% to 98% for more than 2s).
NOTE:
This alarm is disabled when AVR control via binary outputs AVR up and AVR dn
is used (i.e. at least one of these outputs is configured onto a physical or virtual
output terminal).
Alarm output: WrnTestOnLdFail
This output is closed while the WrnTestOnLdFail alarm is present in the alarm list.
This alarm indicates that the Test on load function has failed, i.e. the controller is
in TEST mode, the input Test on load is closed, however, when the gen-set has
been synchronized to the mains and load ramp has been finished there is still
nonzero import from the mains, because the load is higher than the gen-set
capacity.
Alarm output: Sd Oil press B
This output is closed while the Sd Oil press B alarm is present in the alarm list, i.e.
while there is a mismatch between gen-set state (running/stopped) and position of
the input Oil press.
Alarm output: OfL StartBlck
This output is closed while message OfL StartBlck is present in the alarm list. The
message indicates that the setpoints Island enable, ParallelEnable and Synchro
enable are adjusted in such a way, that the genset is not allowed to operate in
current conditions, for example if mains breaker is opened and however island
operation is disabled.
Alarm output: Start blocking
The output is closed while there is the message Start blocking in the alarm list, i.e.
while the input Startblocking is closed.
Alarm output: Fuel theft
