Abstract

It is desired that elevators are not operated when the brake is not completely released. Thus, the disengaging of brakes must be monitored or guaranteed otherwise. For providing guaranteed opening the current for opening the brake is determined and then an additional current is provided to the brakes in order to guarantee the opening. The current for opening the brake is determined by doing a test sequence for each brake individually. In the test sequence one brake is used to hold the elevator. Then a momentum is applied to the elevator for moving the elevator car. The current is determined by increasing the current to the engaged brake gradually until the elevator moves. When the movement is detected the current value is stored. When the elevator is operated regularly the additional current is added to the stored value.
