NOTE:- If a digital input configured to panel lock is active, the LCD will display the
panel lock, changing module modes will not be possible. Viewing the instruments
is NOT affected by panel lock.
To initiate a start sequence in MANUAL, press the
(indicated by an LED indicator beside the button), pressing the START (
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.
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
flashing shutdown
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 5200 series configuration software). Rising oil pressure can also be used to disconnect
the starter motor, however it cannot be used for underspeed or overspeed detection.
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 the mains supply fails or a Remote Start on load signal is applied. If Close
generator has been selected as a control source, the appropriate auxiliary output will then activate.
The generator will continue to run On load regardless of the state of the mains supply or remote start input until the
Auto mode is selected.
If Auto mode is selected, and the mains supply is healthy with the remote start on load signal not active, then the
Remote Stop Delay Timer begins, after which, the load is disconnected. The generator will then run off load
allowing the engine a cooling down period.
Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.
