Duration of the cool down phase is determined by the setpoint
Cooling is performed either at nominal speed (generator voltage and frequency protections are evaluated) or
at idle speed (generator voltage and frequency protections are not evaluated). Selection of the speed is done
by the setpoint
.
The cool down can be finished manually in MAN mode by pressing the STOP button.
If a new start request comes, the cool down will be interrupted and the gen-set will go back to the
stabilization phase. If the cooling was at nominal speed, the stabilization timers will not count down again so
the GCB is ready to be closed (after 2 seconds delay).
When the cool down is finished, the output
is de-energized and
is energized. The engine will stop within the time period determined by the setpoint
. If the engine does not stop within this time, the alarm
will be issued.
The output
is energized until the engine is stopped, but at least for the duration of
. If the
has elapsed and the engine has still not stopped, the
is de-energized for 5 s and then energized again for
and this repeats
until the engine is stopped.
Stopped gen-set evaluation
The gen-set is considered as stopped when all of following conditions are valid:
The engine speed is lower than 2 RPM.
The generator voltage in all phases is lower than 10 V.
None of
Additional running engine indications (page 102)
signals is active.
5.4.10 Alarm management
The controller evaluates two levels of alarms. Level 1 – yellow alarm – is a pre-critical alarm that is only
informative and does not take any action regarding gen-set control. Level 2 – red alarm – represents a critical
situation, where an action must be taken to prevent damage of the gen-set or technology.
One alarm of any type can be assigned to each binary input.
Two alarms (one yellow and one red type) can be assigned to each analog input.
There are also
with fixed alarm types.
Each alarm is written to the
.
Each alarm causes a record to be written into the history log.
Each alarm activates the Alarm and Horn output.
Each alarm can cause sending of a SMS message or an email.
