~YP2 has signal to be input to coils of the safe circuit board terminal 24V and COM there is provided 24V voltages to relay K1, relay K1
Normally opened contact adhesive, YP1 → relay K1 normally opened contacts (now normally opened contact K1 contacts are now switched by 24V → door area
Adhesive) → d → door area signal input point X4 conducting (loop cfgd), door area signal input point X4 has 24V control sources.Door area letter
Number input point X4 has after signal input, and output point Y0 has contact adhesive between output, the detection control of circuit 30 M0 and Y0, is formed back
Road 24V → door area switch YP1 → c → relay K2 coils → e → Y0 → M0 → 0V, relay K2 coils obtain electric, relay K2
Normally opened contact K2 adhesives, now (now inhaled by first 1 → normally opened contact of node K1 (now adhesive) → normally opened contact K2
Close) → the 3rd node 3, there is path between the first node 1 and the 3rd node 3, now the 3rd node 3 has voltage signal.
A. in the case of normal (car door lock is not shorted), elevator is opened purpose floor layer door, gate and opened the door in place
When, equal nonpassage between the first node 1 and the second node 2, the 3rd node 3 and the second node 2, the no-voltage signal of the second node 2,
Therefore door lock short circuit test point X2 no-voltage signals.
If b. car door lock is shorted, now pass through the second 2 → UK1 of node → 3 between the 3rd node 3 and the second node 2
The formation path of node 3, the second node 2 has voltage signal, therefore door lock short circuit test point X2 has voltage signal.
Therefore, whether we can have voltage signal to judge whether car door lock is shorted by door lock short circuit test point X2：
If detecting X2 has voltage signal, it is judged as that car door lock is shorted, master control blackboard newspaper failure does not release before failure that elevator can not be again
The secondary normal operation of startup；If detecting X2 no-voltage signals, it is judged as that layer, car door lock are not shorted.
Above disclosed is only preferred embodiment of the present utility model, can not limit this practicality with this certainly new
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered
