How to Fix / Troubleshooting
Note: Some units may still charge but cannot report energy usage accurately when this error is present.
- Check if charging still works: If charging is allowed, you may temporarily use the charger while scheduling service for the meter.

- Reseat communication cable: Unplug and replug the meter's communication cable to the main control board.
- Configuration check: In the installer menu, verify that the correct meter type and address are selected.
- Replace meter module: If communication cannot be restored, replace the internal energy meter module.
