How to Fix / Troubleshooting
Safety first: Ensure the generator cannot start unexpectedly while you are working by disabling auto-start and opening the ATS control circuit if necessary.
- Review exercise settings: Access the A-iPower controller menu and verify the scheduled exercise time and duration. Adjust to the recommended weekly or monthly interval.
- Check utility sensing: In the ATS, verify that the utility voltage sensing leads are properly connected and tight. Loose connections can cause false outage detection.
- Measure utility voltage: Have a qualified electrician confirm that utility voltage is stable and within spec at the ATS.
- Update controller configuration: Ensure the controller is set for the correct utility voltage and phase.
