6.6.6 STOPPING SEQUENCE
In manual mode the set will continue to run until either :
• The stop button
is pressed – The set will immediately stop
• The auto button
is pressed. The set will observe all auto mode start requests and
stopping timers before beginning the Auto mode stopping sequence.
6.7 TEST MODE
NOTE:- Test Mode is only applicable to DSE7420 controller.
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

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 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.
