Governor Calibration for Paralleling
Generator Sets
Calibration Procedure
1. Place generator master switch to OFF. Generator
set must not be running.
2. Set the gain pot at 30% and the droop pot
completely counterclockwise (CCW).
3. Adjust the idle speed by turning the 20-turn pot
clockwise (CW)
counterclockwise (CCW) to decrease speed.
4. Adjust the run speed by turning the 20-turn pot
clockwise (CW)
counterclockwise (CCW) to decrease speed.
5. Place generator master switch to RUN or TEST
position to start generator set.

2. Use the run speed pot to set the engine rpm to the
desired no load speed (frequency) on the
frequency meter.
3. Apply full load to the generator set.
4. While watching the frequency meter, slowly turn
