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.
Click steps to track your progress.
Observe the door closing operation for any physical obstructions in the door path or track.
