6. COMMISSIONING
PRE-COMMISSIONING
Before the system is started, it is recommended that the following checks are made:-
6.1. The unit is adequately cooled and all the wiring to the module is of a standard and rating
compatible with the system.
6.2. The unit
DC supply is fused and connected direct to the battery and of correct polarity.
6.3. The Emergency Stop input is wired to an external normally closed switch connected to
DC
positive.
NOTE:- If Emergency Stop feature is not required link this input to the DC Positive.
6.1. To check the start cycle 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. Turn the selector switch to
“MANUAL”. The unit start
sequence will commence.
6.2. 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
“FAILED TO START” LED
will be illuminated. Turn to OFF to reset the unit.
6.3. Restore the engine to operational status (reconnect the fuel solenoid), again select
“MANUAL” and this time the engine should start and the starter motor should disengage
automatically. If not then check that 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.
6.4. Select
AUTO on the front panel, the engine will run for the pre-set cooling down period, then
shutdown. The generator should stay in the standby mode. If not check that there is not a
signal present on the
Remote Start input.
6.5. Initiate a remote start by grounding the
Remote Start input. The start sequence will start and
the engine will run up to operational speed. If one of the Auxiliary Outputs has been
configured for Load Transfer, the Generator will accept the load. If not, check the wiring to the
Generator Contactor Coil. Check the Warming timer has timed out.
6.6. Remove the Remote Start signal, 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.
6.7. All internal timers and selections should now be adjusted to the customers specifications or to
the engine and alternator manufacturers recommendations.
6.8. If despite repeated checking of the connections between the
521 and the customers system,
satisfactory operation cannot be achieved, then the customer is requested to contact the
factory for further advise on:-
