In addition, although currently more lift lock loop normal, but also pull the door lock relay, but usually in the door to take a pair of normally open relay contacts and then sent to the computer (or PC) for testing, if the door lock relay contact itself poor state of lock circuit will cause failure.

Safety Edge (photoelectric door, door curtains)
Role:
In order to prevent the passengers caught in elevator doors closing process, it is generally in the elevator door sedan equipped with a safety touch pad (or photoelectric or light curtains).
Safety Edge: one device for mechanical pinch, when the elevator in the closing process, the people met safety edge, safety edge indented, led lower part of a micro switch, safety edge switching, control direction of rotation to open the door...
