4.2 FIRST START
NOTE: It is impossible to predict exactly what happens when the set is first started!
Observe carefully and be prepared to stop the generator. Test Emergency Stop operation prior
to starting. Ensure the previous section is completed fully.
NOTE: Do not apply load to the set until instructed during the following procedure.
NOTE: For further details of module configuration, refer to DSE Publication: 057-271
DSEA108 Configuration Suite PC Software Manual.
Start the generating set and observe the feedback voltage using the SCADA screen and the
voltmeter.
4.2.1 AVR TRIPS AFTER FIRST START
If the AVR trips, the LED flashes. Immediately stop the generating set and then count the flashes.
Take the following action:
LED state
Cause
Action
Rapid Continuous
Flashing
Corrupt configuration
Write the configuration to the AVR again, if this
reoccurs the AVR is faulty and should be returned.
Single Flash
Start-up Failed Trip
(Voltage Feedback
Failed to Reach 70%
of
Set Point
)
Delayed by 10 seconds if the setup instructions
were correctly followed.
Go to the next stability range using the DIP
switches to increase the
Maximum Duty Cycle
.
This may require repeating depending on the duty
cycle the alternator needs.
Two Flashes
Over Excite Trip
Increase the
Over Excite Trip
on the Protections
menu by 50%.
This may require repeating depending on the
excitation voltage the alternator needs.
Three Flashes
Loss of Sensing
Check the feedback wiring as this indicates a loose
connection.
Four Flashes
Under Frequency Trip
Indicates the engine is not up to speed, check the
governor.
Five Flashes
Potentiometer Fault
Indicates that the potentiometer connected to
terminals P1 and P2 has become open circuit.
Steady
UFRO Active
Indicates the engine is not up to speed, check the
governor.
