6.2 MANUAL OPERATION
NOTE:- If a digital input configured to panel lock is active, changing module modes will not be
possible. Viewing the instruments and event logs is NOT affected by panel lock.
Activate Manual mode be pressing the pushbutton. An LED indicator beside the button confirms this action.
Manual mode allows the operator to start and stop the set manually, and if required change the state of the load
switching devices.
6.2.1 WAITING IN MANUAL MODE
When in manual mode, the set will not start automatically.
To begin the starting sequence, press the
button.
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 7000 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.
