Description
NotReady state is shown on the controller screen and the
message appears in the Alarm list. As soon as input is
deactivated, engine start is enabled again.
Wrn CylTemp1-32
A+H
Warning protection on AI Cylinder temperature 1-32 is
active. Check corresponding setpoints in the
Engine
protect
group.
Wrn MCB fail
A+H
MCB failure was detected.
See
Circuit breakers operation sequence, GCB/MCB fail
detection
chapter in IGS-NT-x.y-Reference Guide.
Stp GCB fail
A+H
GCB failure was detected.
See
Circuit breakers operation sequence, GCB/MCB fail
detection
chapter in IGS-NT-x.y-Reference Guide.
Wrn BTB fail
A+H
BTB failure was detected.
See
Circuit breakers operation sequence, GCB/MCB fail
detection
chapter in IGS-NT-x.y-Reference Guide. It
applies to BTB breaker too.
Wrn MGCB fail
MGCB failure was detected.
See
Circuit breakers operation sequence, GCB/MCB fail
detection
chapter in IGS-NT-x.y-Reference Guide. It
applies to MGCB breaker too.
Sd Oil press B
A+H
Engine shut-down was
activated by binary input with “Oil
press” function (see LBI card in GenConfig for information
about source signal for this function).
Wrn RSync fail
A+H
Reverse synchronization failure indication, genset or group
of gensets was not synchronized to mains within
Sync/Load ctrl
:
Sync timeout
time.
Check setting of setpoints in the
Sync/Load ctrl
and
Volt/PF ctrl
groups. Frequency regulation loop, Angle
regulation loop and Voltage regulation loop are active
during synchronisation and you may need to adjust their
setting.
Actual state of synchronization is visible on the controller
measurement screen with synchroscope where speed and
voltage regulator's outputs, slip frequency and generator
and mains voltages can be observed during the
synchronization process.
Stp Sync fail
A+H
Synchronization failure indication (alarm Sync timeout is
active), gen-set or group of gensets was not synchronized
to mains/bus within
Sync/Load ctrl
:
Sync timeout
time.
Check setting of setpoints in the
Sync/Load ctrl
and
Volt/PF ctrl
groups. Frequency regulation loop, Angle
regulation loop and Voltage regulation loop are active
during synchronisation and you may need to adjust their
setting.
Actual state of synchronization is visible on the controller
measurement screen with synchroscope where speed and
