CONTROL ARRANGEMENT AND A METHOD

摘要

A control arrangement of an elevator includes a safety gear, an over speed governor with a rope which is connected to the safety gear, a stopping device for generating an actuating force to the safety gear, and a drive unit for driving the elevator apparatus. In order to facilitate easy and efficient maintenance, the control arrangement includes a controller for controlling a triggered sequence to involve activating of the stopping device for braking with the safety gear, and controlling the drive unit to drive the elevator apparatus during braking with the safety gear until the safety gear stops the elevator apparatus.

1. A control arrangement of an elevator, comprising:
a safety gear for braking an elevator apparatus; an over speed governor with a rope which moves with the elevator apparatus and which is connected to the safety gear for initiating the braking by means of an actuating force transferred via the rope to the safety gem; a stopping device for preventing movement of the rope for generating the actuating force to the safety gear; and a drive unit for driving the elevator apparatus; and a controller for controlling a triggered sequence to involve:
activating the stopping device for braking with the safety gear; andcontrolling the drive unit to drive the elevator apparatus during braking with the safety gear until the safety gear stops the elevator apparatus.
