| Error Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | Blown fuse on power supply or reverse polarity. | Check PSU, measure voltage at terminals 1 & 2 (must be 10-14V DC). | | Card beeps but lock doesn’t open | Lock wired to wrong relay (NO vs NC). | Swap lock wire from NO to COM or NC to COM. | | Lock opens for 1 second then closes | Insufficient power supply amperage (lock surge). | Upgrade to 12V DC 5A PSU. Add a capacitor across lock power. | | Continuous alarm after door closes | Door contact sensor (SEN) stuck or misaligned. | Check reed switch gap (<10mm). Set 16 0 # to disable temporarily. | | “Error” beep (two short beeps) | Command syntax error or user not found. | Re-enter command slowly. Use 14 to verify user exists. | | Master code not accepted | Someone changed it, or keypad is faulty. | Perform emergency reset (jumper method). | | RFID range is <1cm | Interference from metal or voltage drop. | Mount on non-metallic spacer.
