1.2 AUTOMATIC MODE OF OPERATION
The module is activated by turning the selector switch to the AUTO position.
When a
Remote Start signal is applied to the remote start input, the following sequence is
initiated:-
The
Remote Start Present LED illuminates.
To allow for false signals the
Start Delay timer is initiated, after this delay, if the pre-heat output
option is selected this timer is then initiated, and the corresponding auxiliary output which is
selected energises.
NOTE:- If the Remote Start signal is removed during the Start Delay timer the unit will
return to a stand-by state.
After the above delays the Fuel Solenoid is energised, then the Starter Motor is engaged.
The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking
attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence
continue beyond the set number of attempts, the start sequence will be terminated and
Fail to
Start
fault will be displayed by a flashing LED.
