TEST MODE
Test Mode
is activated by pressing the
Test Mode
button.
The
Test Mode
icon is displayed to indicate
Test Mode
operations.
In
Test Mode
, the set does not start automatically.
To begin the starting sequence, press the
Start
button.
STARTING SEQUENCE
The fuel relay is energised and the engine is cranked.
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 is terminated and the display shows
Fail to Start.
The starter motor is disengaged when the engine fires. Speed detection is factory configured to be derived from the AC
alternator output frequency, but can additionally be measured from a Magnetic Pickup mounted on the flywheel or from
the CANbus link to the engine ECU depending on module configuration.
Additionally, rising oil pressure can be used to disconnect the starter motor (but cannot detect underspeed or overspeed).
After the starter motor has disengaged, the
Safety On Delay
timer activates, allowing Oil Pressure, High Engine
Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.
NOTE:
If a digital input configured to panel lock is active, changing module modes is not possible. Viewing the
instruments and event logs is NOT affected by panel lock.
NOTE:
There is no start delay in this mode of operation.
NOTE:
If the unit has been configured for CAN, compatible ECUs receives the start command via CAN.
NOTE:

057-185 DSE71xx MKII Configuration
Software Manual.
