Adjustment Procedure
Start Generator
1. Set the Voltage Adjust potentiometer
on the SR4A or SR8A for Rated Voltage
of generator set. (course adjustment)
2. Use the Voltage Trim potentiometer
to fine tune the Rated Voltage. This is
the potentiometer shown above.
3. The Voltage Trim potentiometer is
now calibrated and should not be
adjusted anymore.
4. Close the Voltage Raise discrete
input (4) and verify the EGCP-2 can
move the generator voltage in the
increase direction.
5. Close the Voltage Lower discrete
input (5) and verify the EGCP-2 can
move the generator voltage in the
decrease direction.
6. The Reactive Load Menu items may
need adjusted for stable Power Factor
control.
