10 COMMISSIONING
10.1 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. Check all mechanical parts are fitted correctly and that all electrical
connections (including earths) are sound.
•
The unit
DC
supply is fused and connected to the battery and that it is of the correct polarity.
•
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. The
module will not operate unless either the Emergency Stop is fitted correctly OR terminal 3 is
connected to DC positive.
•
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
and then press
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
. Select the
position to reset the unit.
•
Restore the engine to operational status (reconnect the fuel solenoid). Select
and then
press
. 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. It will be possible at this time to view the engine and alternator
parameters - refer to the ‘Description of Controls’ section of this manual.
•
Select
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.
•
Initiate an automatic start by supplying the remote start signal (if configured). 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 (if configured), the Generator will accept the load. If not, check the
wiring to the Generator Contactor Coil
(if used)
. Check the Warming timer has timed out.
•
Remove the remote start signal. The return sequence will begin. After the pre-set time, the
generator is unloaded. The generator will then run for the pre-set cooling down period, then
shutdown into its standby mode.
•
Set the modules internal clock/calendar to ensure correct operation of the scheduler and event
logging functions. For details of this procedure see section entitled
Front Panel Configuration –
Editing the date and time.
•
If, despite repeated checking of the connections between the controller and the customer’s
system, satisfactory operation cannot be achieved, then the customer is requested to contact the
factory for further advice on:-
