Abstract: An elevator system includes an elevator car, a hoisting machine moving the elevator car in a hoistway, and a hoisting machine brake having one or more brake pads moving into a brake position where the one or more brake pads contact a braking surface to reduce speed of the elevator car when activated to brake. To provide a solution ensuring reliable operation of the brake, the elevator system includes a temperature sensor providing a signal indicating a temperature of the braking surface, and a monitoring unit monitoring operation of the hoisting machine brake, the monitoring unit receiving the signal indicating the temperature and is configured to indicate a brake fault when the indicated temperature during an elevator run has reached an upper limit value or increased with more than a limit value.

Abstract: A method for ensuring elevator safety in an elevator system, an elevator control unit, an elevator system, and a computer program product are disclosed in this document. The method comprises detecting a foreign object in an elevator shaft during normal operation mode, establishing a safe zone of the elevator shaft, wherein the safe zone is associated with a safe zone speed, a safe distance, and a safe direction, switching operational mode of the elevator system to a safe zone mode, determining that the elevator car is in the safe zone, and allowing movement of the elevator car in the safe zone to the safe direction at a speed not exceeding the safe zone speed.
