Possible Causes
Corrupted firmware or EEPROM on CAME control unit, Surge damage to microcontroller, Incorrect parameter configuration, Failed low‑voltage regulator on board
How to Fix / Troubleshooting
Safety first: Disconnect mains power before opening the control box.
Steps:
- Power cycle: Turn off power for at least 2 minutes, then restore. Observe if E9 clears.
- Factory reset: If the manual allows, perform a factory reset of the CAME control board parameters, then reprogram limits and remotes.
- Inspect board: Look for burn marks, swollen components, or corrosion on the PCB. Any visible damage usually means replacement is required.
- Check low‑voltage outputs: Verify that 24 V outputs for accessories are present and stable. Absence may indicate regulator failure.
Internal control board faults generally are not field‑repairable. Replace the CAME control unit with the same model or a compatible updated version.
