Abstract

A method and a system for disconnecting passenger transport systems, especially escalators and moving walkways. Functional units of a passenger transport system monitor for malfunctions of the passenger transport systems by using switching elements and the signals of the functional units are combined to form a security chain. The signals of the functional units and signals from a drive monitoring unit are supplied to at least one pilot unit. Subsequently, a disconnecting signal is provided to a respective disconnecting contact as a result of a malfunction detected by the functional units and/or the drive monitoring system.
