Elevator maintenance of security and technical points(6/10)

Fault Status:
In the whole department is closed, the door to the control panel to observe the state of the relay, the relay is released if the lock state, you should judge for lock loop is disconnected.
Repair method:
Since most elevator climbing Express are not run off when the door locks, door locks fault though so easy to judge, but it is difficult to figure out which door failure.

My maintenance recommendations:
1. First stop should be the focus of suspicion layer elevator door malfunctions.
2. asked whether layer triangular key opened the door, in the hall with a triangular key to re-look at the hall door switch.
3. Make sure that in the maintenance state, the control panel separate short hall door and hall door, the separation is part of the hall door or car door part of the fault.
4. If so Tingmen partial failure, ensuring the maintenance status, short hall lock loop to run the elevator inspection speed, layer by layer Tingmen check each channel interlock exposure (do not forget the passive door).
Note: After repair door lock circuit fault, we must first take down the door wiring short, can only express elevator to the state will be restored...
