DSE Model 521 Remote Start Engine Management System - Operators Manual

The generator will run off load, unless a
Remote Start signal is applied, and if Load Transfer has
been selected as a control source, the appropriate auxiliary output selected will active.
If the
Remote Start signal is removed, the generator will continue to run On load until the selector
switch is turned to
Auto. The Remote Stop Delay Timer will time out, the load is then
disconnected. The generator will then run
off load allowing the engine a cooling down period.
Turning the selector to
STOP de-energises the FUEL SOLENOID, bringing the generator to a stop.
MANUAL OPERATION WITH EXTERNAL START AND STOP PUSHBUTTONS
If the module has been configured to use external Start and Stop pushbuttons the normal ‘Manual’
mode of operation is over-ridden and the following sequence is observed;
Turn the selector switch to
MANUAL.
To start the set operate the
‘Start’ Push-button, the pre-heat output (if selected) will energise and
the timer is initiated.
Once the above delay has expired the
Fuel Solenoid is energised, then the Starter Motor is
engaged.
The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking
attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence
continue beyond the set number of attempts, the start sequence will be terminated and
Fail to
Start
fault will be displayed by a flashing LED.
When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from
the Alternator output. Alternatively a Magnetic Pickup mounted on the flywheel housing can be used
for speed detection. (This is selected by PC using the
808 interface.) The warning lamp output of
the charge alternator can also be used to disconnect the starter motor, however it cannot be used
for underspeed or overspeed.
After the starter motor has disengaged, the
Safety On timer is activated, allowing Oil Pressure,
High Engine Temperature, Underspeed, Charge Fail and any delayed Auxiliary fault inputs to
stabilise without triggering the fault.
Once the engine is running, the
Warm Up timer, if selected is initiated, allowing the engine to
stabilise before it can be loaded.
The generator will run off load, unless a
Remote Start signal is applied, and then if Load Transfer
has been selected as a control source, the appropriate auxiliary output selected will be activated.
If the
Remote Start signal is removed, the generator will continue to run On load until the selector
switch is turned to
Auto. The Remote Stop Delay Timer will time out, the load is then
disconnected. The generator will then run
off load allowing the engine a cooling down period.
Turning the selector to
STOP or pressing the ‘Stop’ Pushbutton de-energises the FUEL
SOLENOID
, bringing the generator to a stop.
