METHOD FOR MONITORING A BRAKE SYSTEM IN AN ELEVATOR SYSTEM AND CORRESPONDING BRAKE MONITOR FOR AN ELEVATOR SYSTEM

摘要

A brake monitor for monitoring a brake system of an elevator system that includes a drive and a drive controller in addition to the brake system. The brake monitor includes a first brake signal input for electrically connecting the brake monitor to a first brake contact of the brake system and a driving signal input for connecting the brake monitor to a first electrical driving signal line of the drive controller. Also provided are a power supply, a microprocessor and a relay circuit. The relay circuit is configured to be activated for interrupting a safety circuit of the elevator system or for interrupting a control voltage of the drive controller so that the elevator system can be stopped.
