Possible Causes
Incorrect bridging of safety inputs, Misconfigured operating mode, Defective safety input on control board, Faulty wall control wiring
How to Fix / Troubleshooting
Safety first: Ensure the door area is clear. Disconnect power before changing wiring.
Step-by-step:
- Review wiring: At the control board, verify that safety inputs (photocell, safety edge, stop) are wired exactly as per the Hormann diagram. Remove any unauthorized jumpers or incorrect bridges.
- Check wall station: If a Hormann wall console is installed, disconnect it temporarily and test operation with only the remote. A shorted wall button or cable can block closing.
- Operating mode: Some Hormann controls allow “open‑only” or partial modes. Enter the programming menu and confirm that standard automatic mode is selected.
- Test safety devices: Confirm that photocells and safety edges are functioning and not permanently triggered.
- If error persists: The logic input section of the control board may be defective and require replacement.
