Probable Faulty Locations
1)Operation error
2)Door close confirmation LS; corresponding dog position error
3)Something has been caught between the door.

Measures to Take
1)Do not open the door while the spindle is rotating or the axis is moving.
2)If the LS is defective, replace it. Adjust the dog position so that limit switch is always actuated while the door is closed.
3)Remove a foreign substance.
