Possible Causes
Governor misadjustment, Incorrect controller frequency setting, Worn governor linkage, Engine wear affecting speed control
How to Fix / Troubleshooting
Safety first: Frequency adjustments affect all connected loads. Only trained personnel should make governor changes.
- Confirm controller setting: Ensure the Genergy controller is configured for the correct nominal frequency (50 or 60 Hz) for your region.
- Check no‑load frequency: With the generator breaker open, run the unit and measure frequency. Adjust the governor setpoint per the service manual to bring it into spec.
- Test under load: Apply typical load and verify that frequency remains within ±2% of nominal. If droop is excessive, adjust governor droop or gain settings.
- Inspect linkage: Replace worn or loose linkage components that prevent precise speed control.
