Generator does not exercise at scheduled time
Advertisements
Possible Causes
Incorrect date/time or schedule settings, disabled exercise mode, controller firmware issue, low battery preventing start.
How to Fix / Troubleshooting
Safety first: Ensure the generator is in AUTO mode and that no active alarms are present before adjusting settings.
Steps:
- Check clock: Set the correct date and time on the Honeywell controller.
- Verify exercise settings: Confirm that the exercise function is enabled and scheduled for the desired day and time.
- Battery status: Ensure the battery is healthy and that no 'Low Battery' alarm is present.
- Manual test: Run a manual test to confirm the unit can start and run. If a manual test works but the exercise function does not, the controller may need a firmware update or replacement.
