How to Fix / Troubleshooting
Safety first: Keep the area clear until behavior is corrected.
- Check logic settings: Enter the Nice programming menu and review logic and auto‑close parameters. Disable auto‑close if not desired.
- Monitor safety devices: Watch photocells and safety edge after the door closes. If they trigger due to vibration or misalignment, the controller may reopen the door.
- Inspect limit switches: Ensure the close limit switch is firmly actuated and not bouncing due to vibration. Adjust cam position or replace the switch if necessary.
