AUTOMATIC MODE
Note: If a digital input configured to Panel Lock is
active, changing module modes is not be
possible. Viewing the instruments and event
logs is NOT affected by Panel Lock.
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
Note: If the unit has been configured for CAN, com-
patible ECU’s receive the start command via
CAN and transmit the engine speed to the DSE
controller. For further details of module
configuration, refer to DSE Publication:
057-223 DSE60xx MKII Configuration Software
Manual.
If a starting request is made, the starting sequence
begins. Starting requests can be from the following sourc-
es:
Stopping Sequence
Engine Running
Note:
The load transfer signal remains inactive until
the Oil Pressure has risen. This prevents
excessive wear on the engine.
Once the engine is running and all starting timers have
expired, the animated Engine Running icon is
displayed.
The generator is placed on load if configured to do so. If
all start requests are removed, the stopping sequence
begins.
Failure of mains supply (DSE6020 MKII only).
Activation of an auxiliary input that has been configured
to Remote Start or Auxiliary Mains Fail (DSE6020 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 dura-
tion 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 CAN link to the
engine ECU depending on module.
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.
The Return Delay timer operates to ensure that the start-
ing request has been permanently removed and isn’t just
a short term removal. Should another start request be
made during the cooling down period, the set returns on
load.
If there are no starting requests at the end of the Return
Delay timer, the load is removed from the generator to the
mains supply and the cooling timer is initiated.
The Cooling Down timer allows the set to run off load and
cool sufficiently before being stopped. This is particularly
important where turbo chargers are fitted to the engine.
After the Cooling Down timer has expired, the set is
stopped.
