1.3 MANUAL OPERATION
NOTE:- The following sequence is only applicable to controllers not using external
start/stop push-button control.
To initiate a start sequence in MANUAL, turn the selector switch to MANUAL .
NOTE:- There is no Start Delay in this mode of operation.
If the pre-heat output option is selected this timer is then initiated, and the auxiliary output selected
is energised.
After the above delay 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 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.
