Technical Handbook 153
In manual mode, the board always performs only one starting attempt, and then it always
performs it on battery #1.
The automatic starting sequence is:
•
BATT1 output enabled , BATT2 output disabled .
•
2-second wait (note 1).
•
First crank attempt.
•
Pause
•
…...
•
Last crank attempt.
•
2 seconds delay
•
BATT1 output disabled , BATT2 output disabled .
•
2 seconds delay
•
Only if BATT2 output exists: BATT1 output disabled , BATT2 output enabled .
•
Only if BATT2 output exists: 2-second wait (note 2).
•
First crank attempt with the second battery.
•
Pause
•
…...
•
Last crank attempt with the second battery.
•
Failed start alarm.
•
2 seconds delay.
•
BATT1 output disabled , BATT2 output disabled .
Note 1: the two -second initial delay between the selection of battery #1 and the starter motor
control is performed at the same time of the pre-lubrication cycle and the glow plugs pre-
heating cycle, and it could be extended to the longer time between those configured in P.0242
and P.0209.
If the engine starts up, the sequence ends. The output BATT1 or BATT2 active in that moment
is disabled after a
2 seconds delay after detecting started engine.
These two controls are activated simultaneously at the beginning of the starting sequence.
Both remain active even with started engine, until the starting of the shutdown sequence:
The ECU_ENABLE control is removed immediately at the beginning of the shutdown
sequence.
The FUEL control is removed after P.0234 seconds ("delay between STOP and FUEL
controls") from the starting of the stopping cycle.
The FUEL control should be used to control the solenoid valve placed on the fuel line. At the
beginning of the starting sequence, the board opens the valve, thus allowing the fuel to get to
the engine. At the beginning of the stopping sequence, the board closes the solenoid valve:
the engine receives no more fuel and then it stops.
