10 COMMISSIONING
10.1.1 PRE-COMMISSIONING
Before the system is started, it is recommended that the following checks are made:-
10.1. 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.
10.2. The unit DC supply is fused and connected to the battery and that it is of the correct polarity.
10.3. 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. The module will
not operate unless either the Emergency Stop is fitted correctly OR terminal 3 is connected to DC positive.
10.4. Make all checks on the engine and alternator as detailed by their respective manufacturer documentation.
10.5. Check all other parts in the system according to the manufacturer documentation.
10.6. Thoroughly review the configuration of the DSE controller and check that all parameters meet the
requirements of your system.
10.7. 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 then press “START” the unit start sequence will commence.
10.8. 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 STOP/RESET
position to reset the unit.
10.9. Restore the engine to operational status (reconnect the fuel solenoid). Select “MANUAL” and then press
“START”. This time the engine will start and the starter motor will disengage automatically. If not then check
the engine is fully operational (fuel available, etc.) and the fuel solenoid is operating. The engine will now run
up to operating speed. If not, and an alarm is present, check the alarm condition for validity, and check input
wiring. The engine will continue to run for an indefinite period. At this time to view the engine and alternator
parameters - refer to the ‘Description of Controls’ section of this manual.
10.10. Fully commission the engine/alternator and any other parts in the system as detailed in the respective
manufacturer documentation. This includes load bank testing, load acceptance, breaker control and more.
10.11. When building a synchronising system, follow the DSE “4 Steps To Synchronising” as detailed elsewhere in
this document before attempting to parallel the set with another supply.
10.12. 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.
10.13. If despite repeated checking of the connections between the DSE87xx series controller and the customer’s
system, satisfactory operation cannot be achieved, then the customer is requested to contact the factory for
