|---|
Do not operate generator at a voltage greater than 5% above the name plate rating. |
The factory calibration adjustment (1) should be used by the factory technicians only. The following procedure can be used if the factory calibration has been disturbed:
- Remove the seal from the factory calibration adjustment (1) .
- Start the genset.
- Run the genset at no load.
- Turn the factory calibration adjustment (1) in a fully counterclockwise direction.
- Turn the voltage adjust rheostat (2) in a fully clockwise direction.
- Slowly turn the factory calibration adjustment (1) CW until the voltage on 20-22-24 is 144 ± 1 ACV.
- Turn the voltage adjust rheostat (2) CCW.
- Verify that the voltage on 20-22-24 is less than 90 ACV. The unit is calibrated.
- Seal the factory calibration adjustment (1) .
