1.2 AUTOMATIC MODE OF OPERATION

This mode is activated by pressing the

confirms this action.

Whether the start sequence is initiated by mains (utility) failure or by remote start input, the

following sequence is followed:

To allow for short term mains supply transient conditions or false remote start signals, the Start

Delay timer is initiated. After this delay, if the pre-heat output option is selected then the pre-heat

timer is initiated, and the corresponding auxiliary output (if configured) will energise.

NOTE:- If the mains supply returns within limits, (or the Remote Start signal is

removed if the start sequence was initiated by remote start) during the Start Delay timer,

the unit will return to a stand-by state.

After the above delays the Fuel Solenoid is energised, then one second later, 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 rest period. Should this sequence continue

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

Fail to Start

fault 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, 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 accepting the load.

If the remote start is being used and has been configured to Remote start is on load, or the mains

has failed, the load will be transferred to the generator.

On the return of the mains supply, (or removal of the Remote Start signal if the set was started by

remote signal), the Stop delay timer is initiated. Once it has timed out, the load is transferred back

to the mains (utility). The Cooling timer is then initiated, allowing the engine a cooling down period

off load before shutting down. Once the Cooling timer expires the Fuel Solenoid is de-energised,

bringing the generator to a stop.

If the mains should fail (or a Remote Start signal is re-activated) whilst the generator is Cooling

down, the load will be immediately transferred to the generator.

Should the mains supply fall outside limits again (or the Remote Start signal be re-activated)

during the cooling down period, the set will return on load.

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

not be changed.
