[Diesel] Start sequence
The relay "Preglow" will be energized for the preheating time period ("Pre‐
glow" is displayed). Following preheating, the fuel solenoid is first energized
and then the starter is engaged ("Start" is displayed).
When the configured firing speed is exceeded, the starter is disengaged and
the fuel solenoid remains energized via the firing speed. "Ramp to rated" is
displayed until the engine monitoring delay timer expires and the start
sequence has finished.
If the engine fails to start, a start pause is initiated ("Start - Pause" is dis‐
played). If the number of unsuccessful start attempts reaches the configured
value, an alarm message will be issued ("Start fail" is displayed).
Stop sequence
After opening the GCB, the coasting time starts and the engine runs without
load ("Cool down" is displayed). On termination of the coasting time, the fuel
solenoid is de-energized, and the engine is stopped ("Stop engine" is dis‐
played). If the engine cannot be stopped via the fuel solenoid, the alarm mes‐
sage "Eng. stop malfunct." is displayed.
