Possible Causes
Engine speed instability, Faulty governor actuator, Incorrect frequency setting in controller, AVR or alternator issues affecting speed feedback
How to Fix / Troubleshooting
Safety first: Isolate the generator from the load. Disable AUTO mode before making adjustments.
- Check engine speed: Use a frequency meter or multimeter with Hz function on the generator output. For 50 Hz models, speed should be ~1500 or 3000 RPM; for 60 Hz, ~1800 or 3600 RPM depending on design.
- Inspect governor actuator: On electronic-governed engines, check the actuator linkage for binding. Listen for hunting or surging. Loose linkages can cause unstable frequency.
- Controller settings: Verify that the nominal frequency and speed parameters in the Pramac controller match the generator rating plate.
- Professional adjustment: Fine-tuning governor gain and stability usually requires a technician with the proper tools. Avoid random adjustments that can worsen instability.
