1 DESCRIPTION OF OPERATION

1.1 MANUAL MODE OPERATION

To initiate a start sequence in MANUAL, press the pushbutton, and the start sequence is
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

fault

will be illuminated.
When the engine fires, the star ter 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.

1.2 AUTOMATIC MODE OF OPERATION

This mode is activated by pressing the pushbutton. An LED indicator beside the button
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 star ter 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.
