AUTOMATIC MODE
Auto Mode is activated by pressing the Auto Mode button .
The
Auto Mode
icon is displayed to indicate
Auto Mode
operations.
Auto Mode allows the generator to operate fully automatically, starting and stopping as required with no user
intervention.
WAITING IN AUTO MODE
If a starting request is made, the starting sequence begins.
Starting requests can be from the following sources:
• Failure of mains supply (DSE7120 MKII only).
• Activation of an auxiliary input that has been configured to Remote Start or Auxiliary Mains Fail (DSE7120 MKII Only).
• Activation of the inbuilt exercise scheduler.
STARTING SEQUENCE
To allow for ‘false’ start requests, the start delay timer begins.
Should all start requests be removed during the start delay timer, the unit returns to a stand-by state.
If a start request is still present at the end of the start delay timer, 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 over-
speed).
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 external panel lock is active, changing module modes is not possible. Viewing the
instruments and event logs is NOT affected by panel lock.
NOTE: If the unit has been configured for CAN, compatible ECU’s receive the start command via CAN and transmit the
engine speed to the DSE controller.
NOTE: For further details of module configuration, refer to DSE Publication: 057-185 DSE71xx MKII Configuration
Software Manual.
