DSE 560 - Manual Operation with External Pushbuttons

DSE Model 560 Automatic Start Engine Management and Instrumentation System Operators Manual
560 OPERATING MANUAL ISSUE 5 4/4/02 MR 9
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 external ‘Start’ Pushbutton, 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 accompanied by a flashing red 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, Under-speed, 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 if Load Transfer has
been selected as a control source, the appropriate auxiliary output selected will activate.
NOTE:- It is possible to have a manual run on-load by using ‘Load Transfer (Always)’ -
Refer to the P808 for windows manual for further details.
If the Remote Start signal is removed, the generator will continue to run On load until the selector
switch is turned to Auto. The 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.
NOTE:- A version of the module is available which has the start button built into the
front fascia of the module. Operation of this module is as detailed above.
