8 COMMISSIONING
8.1 PRE-COMMISSIONING
Before the system is started, it is recommended that the following checks are made:-
The unit is adequately cooled and all the wiring to the module is of a standard and rating
compatible with the system.
The unit DC supply is fused and connected to the battery and that it is of the correct polarity.
To check the start cycle operation take appropriate measures to prevent the engine from starting
(disable the operation of the fuel solenoid). After a visual inspection to ensure it is safe to proceed,
connect the battery supply. Select “MANUAL” and press the START button. The unit start
sequence will commence.
The starter will engage and operate for the pre-set crank period. After the starter motor has
attempted to start the engine for the pre-set number of attempts the LCD will display ‘Failed to
start’.
Restore the engine to operational status (reconnect the fuel solenoid), again select “MANUAL” and
press the START button. This time the engine should start and the starter motor should disengage
automatically. If not then check the engine is fully operational (fuel available, etc.) and that the fuel
solenoid is operating. The engine should now run up to operating speed. If not, and an alarm is
present, check the alarm condition for validity, then check input wiring. The engine should continue
to run for an indefinite period.
Select “AUTO” on the front panel, the engine will run for the pre-set cooling down period, then stop.
The generator should stay in the standby mode. If not check that there is not a signal present on
the Remote start input and that the mains (utility) supply is healthy and available.
Initiate an automatic start by supplying the remote start signal or failing the mains (utility) supply.
The start sequence will commence and the engine will run up to operational speed. Once the
generator is available a load transfer will take place, the Generator will accept the load. If not,
check the wiring to the Generator switching device.
Remove the remote start signal and/or ensure the mains (utility) supply is healthy, the return
sequence will start. After the pre-set time period, the load will be removed from the generator. The
generator will then run for the pre-set cooling down period, then shutdown into it’s standby mode.
If despite repeated checking of the connections between the 720 and the customer’s system,
satisfactory operation cannot be achieved, then the customer is requested to contact the factory for
