6.2.2
STARTING SEQUENCE
NOTE:- There is no start delay in this mode of operation.
The fuel relay is energised and the engine is cranked.
NOTE:- If the unit has been configured for CAN, compatible ECU’s will receive 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 will be
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 but can additionally be measured from a Magnetic Pickup mounted on the flywheel (Selected by PC
using the 71xx series configuration software).
Additionally, rising oil pressure can be used disconnect the starter motor (but cannot detect underspeed or overspeed).
NOTE:- If the unit has been configured for CAN, speed sensing is via CAN.
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.
