Check for any abnormal noise or vibration on
the generating set.
Check if the exhaust system has any leakage.
Monitor the generating set operation by means
of the gauges on the control panel.
Check the engine temperature and oil pressure
by means of the gauges on the panel. Oil pressure
must reach the normal value 10 seconds after
the generating set operation.
Monitor the generating set outlet voltage and
frequency by means of the gauges on the panel.
Check on the voltmeter, if the voltage between
phases is 400 V and between phase and neutral
is 230 V. Check that the frequency at idle is 51-
52 Hz (for 50 Hz operation or 61-62 Hz for 60
Hz operation) on generating sets with mechanical
governors and 50 Hz or 60 Hz on generating sets
with electronic governors. Outlet voltage is
adjusted ex-factory. Adjustments should be done
only by authorized personnel.
If an engine block water heater is not available,
put the generating set under load after warming
with a 10 minute idle run (manual models).
Putting the generating set under load must be
done as follows:
Set the alternator outlet switch on the panel to
ON position.
Set the load switches (or fuses) on the distribution
panel to ON position one by one. This way, the
generating set cannot be suddenly put under full
load. Otherwise, the engine stalling or alternator
winding insulation deformation or burning can
occur.
Set the alternator outlet switch on the circuit to
OFF position before you stop the generating set.
Continue to run the unloaded diesel engine for
the purpose of cooling for 5 minutes and then
stop.
Never operate the generating set before removing
any fault, if any.
NOTE: If a digital input configured to panel lock
is active, the LCD will display the icon. When
in panel lock, changing modules will not be possible.
Viewing the instruments and event logs
is not affected by panel lock.
To initiate a start sequence in TEST, press the
pushbutton. When the controller is in the
test mode (indicated by an LED indicator beside
the button), pressing the START (1) button will
initiate the start sequence.
NOTE: There is no Start Delay in this mode of
operation.
The Fuel Solenoid is energized, then the Starter
Motor is engaged. The engine is cranked for a
preset time period. If the engine fails to fire during
this cranking attempt then the starter motor is
disengaged for the pre-set rest period. Should
this sequence continue beyond the set number
of attempts, the start sequence will be terminated
and Fail to Start fault will be displayed
accompanied by a flashing shutdown indicator.
The generator will continue to run on load
regardless of the state of the mains supply or
remote start input until the Auto mode is selected.
If Auto mode is selected, and the mains supply is
healthy with the remote start on load signal not
active, then the Remote Stop Delay Timer begins,
after which, the load is disconnected. The
generator will then run off load allowing the
engine a cooling down period.
Selecting STOP (0) removes the Close Generator
output (if configured) and de-energises the Fuel
Solenoid, bringing the generator to a stop.

CONTROLS WHICH MUST BE
DONE AFTER STARTING UP
THE GENERATING SET
9. STOPPING THE GENERATING SET
Before stopping the generator, alternator
output, circuit braker should be OFF position.
The genset should run 2-3 minute with no
load.
To stop the generator turn the key switch
to the STOP O position, de-energises key
switch the fuel solenoid, bringing the generator
to a stop.
