Abstract

See full text

A safety monitoring device of an elevator system having a shaft extending over at least two floors has a safety circuit with door contact switches being closed or opened accordingly when a respective shaft door is closed or opened. The door switches form an electrical series circuit that is electrically broken to block the elevator car from moving when any of the door switches is opened. The monitoring apparatus has at least one bypass switch that actuates a first door switch for a first shaft door on a first floor such that, when the elevator car reaches the first floor, the bypass switch bypasses the first door switch to switch the safety circuit independently of the first door switch. A monitoring means of the monitoring apparatus monitors the switching state of the safety circuit and/or of a second door switch for a second shaft door on a second floor.
