 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 Cooling Speed.
 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 immediately ready to be closed.
When the cool down is finished, the output Fuel Solenoid is de-energized and Stop Solenoid is
energized. The engine will stop within the time period determined by the setpoint Stop Time. If the
engine does not stop within this time, the alarm Stop fail will be issued.
The output Stop Solenoid is energized until the engine is stopped, but at least for the duration of Stop
Time. If the Stop time has elapsed and the engine has still not stopped, the stop solenoid is de-
energized for 5 s and then energized again for max. Stop time and this repeats until the engine is
stopped.
The output Ignition is continuously energized until the engine is stopped.
6.13.1 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 revs (RPM).
 The generator voltage in all phases is lower than 50 V.
 None of additional running indication signals is active. See the chapter Speed sensing for
details.
6.14 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 built-in alarms with fixed alarm types.
 Each alarm is written to the Alarmlist.
 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 e-mail.
