Sustained operation on a door with an obstruction can result in damage to
drive.
1. Object or person obstructing door movement.

detection range not matching operator's opening speed. Door is
unavoidably contacted by person using door.

speed should be increased.

Locking alarm
• Door is blocked while in
the closed position.
1. Most common cause of this error is the drive unit attempting to open a
locked door.

• Lock switch detects the lock pin's switching status and switches the drive
unit off if necessary.
3. It is recommended to use a lock status switch, as repeated attempts to
open a locked door may damage the drive unit or the door.
