Description
Sd Underspeed SD
During starting of the engine when the RPM reach the value of
Starting RPM (page 191) setpoint the starter is switched off and the
speed of the engine can drop under Starting RPM (page 191) again.
Then the Underspeed protection becomes active. Protection
evaluation starts 5 seconds after reaching Starting RPM (page 191) .
Emergency Stop SD
If the input Emergency Stop is opened shutdown is immediately
activated.
GCB Fail SD Failure of generator circuit breaker.
Sd RPM
Measurement Fail
SD
Failure of magnetic pick-up sensor for speed measurement. This
alarm appears, if starter was disengaged for other reason than
overcrossing Starting RPM (page 191) (like oil pressure or D+) and
at the end of timer Maximum Cranking Time (page 190) there are
no RPMs > Starting RPM (page 191) detected.
Wrn Stop Fail WRN
Gen-set stop failed. See description at Gen-set Operation States
chapter.
Wrn Maintenance 1 WRN
The period for servicing is set by the Maintenance Timer 1 (page
219) setpoint. The protection comes if counter reaches zero.
Wrn Maintenance 2 WRN
The period for servicing is set by the Maintenance Timer 2 (page
220) setpoint. The protection comes if counter reaches zero.
Wrn Maintenance 3 WRN
The period for servicing is set by the Maintenance Timer 3 (page
220) setpoint. The protection comes if counter reaches zero.
Charge Alternator
Fail
WRN Failure of alternator for charging the battery.
Sd Override WRN The protection is active if the output Sd Override is closed.
Generator CCW Rot WRN
Genset voltage phases are not wired correctly. GCB closing is
prohibited by chontroller.
Note: This table does not contain all alarms in controller. It is only list of the most common alarms.
5.5.10 History log
The history log is an area in the controller’s non-volatile memory that records “snapshots” of the system at
moments when important events occur. The history log is important especially for diagnostics of failures and
problems. When the history file is full, the oldest records are removed.
Each record has the same structure and contains:
• The event which caused the record (e.g. “Overspeed alarm” or “GCB closed”)
• The date and time when it was recorded
• All important data values like RPM, kW, voltages, etc. from the moment that the event occurred.
