Testing method for unintended car movement protection device for elevators and unintended car movement protection device for elevators

An unintended car movement protection device for an elevator comprising:

• an opened or closed door detector including a car door switch and a landing door switch;
• a position detector for detecting a position of a car in a hoistway;
• and
• a control device configured to place a braking device into a braking mode and to cut off power supply to an electric motor to drive the car when it is determined based on a signal from the opened or closed door detector and the position detector respectively that the car entails unintended car movement,
• wherein the control device enables a floor releveling operation by way of an elevator control device in such a closed door state that the car door and the landing door are closed, to control an operation of the car when making the unintended car movement protection device operate for testing to check an operation of the unintended car movement protection device while simulatively setting an opened door detection state of the opened or closed door detector, in which the car door or the landing door are detected to be opened and a power cut-off command signal to be outputted to the electric motor to drive the car, and
• wherein the elevator control device is configured to check the operation of the unintended car movement protection device by making the car in the closed door state move by unbalanced torque in accordance with the power cut-off command signal when the car lands on the releveled floor through the floor releveling operation.
