Start Functions
The controller unit will start the genset when the start command is given. The start
sequence is deactivated when the remove starter event occurs or when the running
feedback is present.
The reason for having two possibilities to deactivate the start relay is to be able to delay
the alarms with run status.
If it is not possible to activate the run status alarms at low revolutions, the remove
starter function must be used.
An example of a critical alarm is the oil pressure alarm. Normally, it is configured
according to the shutdown fail class. But if the starter motor has to disengage at 400
RPM, and the oil pressure does not reach a level above the shutdown setpoint before
600 RPM, then the genset would shut down if the specific alarm was activated at the
preset 400 RPM. In that case, the running feedback must be activated at a higher
number of revolutions than 600 RPM.
