TESTING METHOD FOR UNINTENDED CAR MOVEMENT PROTECTION DEVICE FOR ELEVATORS AND UNINTENDED CAR MOVEMENT PROTECTION DEVICE FOR ELEVATORS

WIPO Patent Application WO/2021/005656

A1

A testing method for an unintended car movement protection device for elevators is disclosed that can reduce test time. In this testing method: a passenger car (100) is moved to a position at which a floor releveling operation is enabled, test operation of an unintended car movement protection device is performed, and a floor releveling operation by an elevator control device (108) for controlling passenger car operations is enabled by way of a command signal from a control device (1) for the unintended car movement protection device; the control device for the unintended car movement protection device is set so as to simulate an open door detected state, in which an open car door (110) or landing door (109) is detected, and to output a power shut-off command signal to an electric motor (105) that drives the passenger car; and then, the floor releveling operation is executed by the elevator control device while in a closed door state, in which the car door and the landing door are closed, and when the passenger car floor is level with the landing by way of the floor releveling operation, the passenger car is moved because of unbalanced torque while in the closed door state in accordance with the power shut-off command signal.
