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
negative.
NOTE: If Emergency Stop feature is not required, link the input to the DC Negative or
disable the input. For further details of module configuration, refer to DSE Publication:
057-
201 DSE46xx Configuration Software Manual.
•
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. Press the
Manual/Start
Mode
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
. Press the
Stop/Reset Mode
button to reset the unit.
•
Restore the engine to operational status (reconnect the fuel solenoid). Press the
Manual/Start
Mode
button. 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.
•
Press the
Auto Mode
button, 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
the delayed load outputs will activate, the Generator will accept the load. If not, check the wiring
to the delayed load output contactors. 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
•
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 the DSE
Technical Support Department
