1 DESCRIPTION OF OPERATION

To initiate a start sequence in MANUAL, press the

initiated.

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 10 second period. If the engine fails to fire during this cranking attempt

then the starter motor is disengaged for a 10 second period. Should this sequence continue

beyond the 3 starting attempts, the start sequence will be terminated and Fail to Start

will be illuminated.

When the engine fires, the starter motor is disengaged and locked out at 20 Hz measured from the

Alternator output. 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 (which is fixed at 12

seconds), 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, at which point the load will be transferred to the generator.

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

de-energises the FUEL SOLENOID, bringing the generator to a stop.

NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can

not be changed.
