6.7 TEST MODE
NOTE:- Test Mode is only applicable to DSE7220/DSE7320 controllers.
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 test mode be pressing the pushbutton. An LED indicator beside the button confirms this action.
Test mode will start the set and transfer the load to the generator to provide a
Test on load function.
6.7.1 WAITING IN TEST MODE
When in test mode, the set will not start automatically.
To begin the starting sequence, press the button.
6.7.2 STARTING SEQUENCE
The set begins to crank.
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.
