Possible Causes
Failed RFID antenna or reader PCB, Disconnected ribbon cable to RFID module, Physical damage to front panel around reader, Firmware configuration disabling RFID unintentionally
How to Fix / Troubleshooting
Safety first: Isolate power before opening the front panel.
- Check configuration: Verify in the Siemens app or web interface that RFID authentication is enabled.
- Test multiple cards: Try several known-good RFID cards to rule out card failure.
- Inspect connections: With power OFF, remove the front cover and reseat the connector between the RFID reader and main control board.
- Physical inspection: Look for cracks or impact damage around the reader area that could have broken the antenna.
If the reader remains unresponsive after these checks, replace the RFID reader module according to Siemens service instructions.
