Possible Causes
Incorrect system voltage or phase setting, Mismatched frequency configuration, Corrupted controller settings, Unauthorized parameter changes
How to Fix / Troubleshooting
Safety first: Turn OFF the generator and isolate it from utility power at the main breaker before changing any configuration.
- Review nameplate: Check the generator nameplate for rated voltage, phase, and frequency (e.g., 120/240V single‑phase, 60 Hz).
- Enter setup menu: Access the controller configuration menu per the DuroMax manual. Verify that voltage, phase, and frequency settings match the nameplate.
- Restore defaults: If settings appear corrupted, use the controller's "factory reset" or "restore defaults" function, then re‑enter only the required site‑specific parameters (date/time, exercise schedule, etc.).
- Lock configuration: After correcting settings, enable any configuration lock or password to prevent accidental changes.
- Controller replacement: If E17 persists and settings cannot be saved, the control module may be faulty and require replacement.
