Failure in Closing the Lock

Kone · Frequency Inverter

What does 06 mean?

This error is recorded if the door fails to close properly within 15 seconds, despite the door-closing signal being continuously present. It triggers after eight continuous occurrences. It also occurs if the door-close limit signal disagrees with the door-lock position for 4 continuous seconds (excluding cases of missing door-lock signals), indicating an overtime condition in door closing.

Common Causes

  • The door mechanism fails to complete the closing sequence within the 15-second time limit.
  • Mechanical obstruction physically preventing the door from closing fully.
  • Faulty door motor or an issue within the door control circuit.
  • Disagreement between the door-close limit signal and the actual door-lock position for more than 4 seconds.
