4. Follow the controller instructions to step to the
voltage gain adjustment menu. Adjust the voltage
gain (parameter 2P) until the light flicker minimizes.
Save the settings.
5. Check and readjust the voltage if necessary.
6. Save the settings.
Note:
The controller will revert to the previous
settings at the next startup if the changes
are not saved.
7. Stop the generator set.

5.8 Voltage Reconnection
Voltage Reconnection is covered in the generator set
Installation Manual. See the List of Related Materials for
the document number.
5.9 Governor System
The frequency of the alternator output is determined by
the speed of the engine. A two-pole alternator must be
driven at 3600 RPM to provide 60 Hertz and 3000 RPM
to provide 50 Hertz. The engine speed is maintained by
the Engine Control Module (ECM).
See the engine
documentation for ECM information.
5.10 Fault Shutdown Tests
Verify the operation of the generator set overspeed,
overcrank, and low oil pressure shutdowns by
performing the following tests.
If these tests are
inconclusive,
test
individual
shutdown
circuit
components (wiring harness, switch, etc.) as described
elsewhere in this section.
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving parts.
WARNING
Servicing the generator set when it is operating. Exposed
moving parts can cause severe injury or death.
Keep
hands, feet, hair, clothing, and test leads away from the belts
and pulleys when the generator set is running.
Replace
guards, screens, and covers before operating the generator
set.
Short circuits.
Hazardous voltage/current can cause
severe injury or death.
Short circuits can cause bodily injury
and/or equipment damage
.
Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
5.10.1 Controller Fault Shutdown
Functions
Check the operation of the fault functions programmed
in the ADC 2100 by performing the following tests. If the
ADC 2100 does not operate as described, check the
controller configuration settings; see Section 4.11. Also
check the controller wiring and connections.
