Possible Causes

How to Fix / Troubleshooting

Safety first: Access control components are low‑voltage, but the enclosure also contains live parts. Only qualified personnel should open the unit.

Steps to try:

  • Test multiple cards: Try more than one authorised RFID card or tag to rule out a single bad card.
  • Check app settings: Ensure RFID access control is enabled and that your cards are correctly registered in the Hager app or backend.
  • Reboot and update: Power‑cycle the charger and check for firmware updates that may address RFID issues.
  • Technician inspection: If E15 persists, a technician should open the front cover, check the RFID reader connection to the main board, and inspect the antenna.
  • Replace RFID module: If the reader is unresponsive, replace the RFID reader/antenna assembly with a compatible Hager part.
