If the unit has been configured for CAN, compatible ECU's receives the start command via CAN.
If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the crank rest
duration after which the next start attempt is made. Should this sequence continue beyond the set number of
attempts, the start sequence is terminated and the display shows Fail to Start.
When the engine fires the starter motor is disengaged. Speed detection is factory configured to be derived
from the main alternator output frequency.
Additionally, rising oil pressure can be used to disconnect the starter motor (but cannot detect under speed
or over speed).
After the starter motor has disengaged, the safety on timer activates, allowing oil pressure, high engine
temperature, under-speed, charge fail and any delayed auxiliary fault inputs to stabilise without triggering the
fault.
Engine Running
Once the engine is running and all starting timers have expired, the animated `Engine Running' icon is
displayed.
In manual mode, the load is not transferred to the generator unless a `loading request' is made. A loading
request can come from a number of sources.
• Activation of an auxiliary input that has been configured to Remote Start On Load or Auxiliary Mains
Fail.Activation of the inbuilt exercise scheduler if configured for `on load' runs.
The load transfer signal remains inactive until the Oil Pressure has risen. This prevents excessive wear on
the engine.
Once the generator has been placed on load, it is not automatically removed. To manually remove the load
either:
• Press the AUTO mode button to return to automatic mode. The set observes all auto mode start requests
and stopping timers before beginning the `Auto Mode Stopping Sequence'.
• Press the STOP/RESET mode button to remove load and stop the generator.
• Activation of an auxiliary input that has been configured to generator load inhibit.
Stopping Sequence
In manual/start mode the set will continue to run until either:
1. The STOP/RESET mode button is pressed - The delayed load outputs are de-activated immediately and
the set immediately stops.
2. The AUTO mode button is pressed. The set observes all auto mode start requests and stopping timers
before beginning the 'Auto Mode Stopping Sequence'.
Maintenance Alarm
Depending upon module configuration one or more levels of engine maintenance alarm may occur based upon
a configurable schedule.
