Abstract
A circuit is described for monitoring the faultless state and/or for detecting the faulty state of a cable railway or chairlift system, with a plurality of monitoring and detection devices ( ) and with at least one control and evaluation unit ( ), the monitoring and detection devices ( ) being series-connected to one another and to the control and evaluation unit ( ) and having the potential to be interrogated with respect to their state, especially with respect to their operating state. To be able to meet safety requirements which are as high as possible and at the same time to require only a small installation space, each monitoring and detection device ( ) has several different influence areas ( ) and several signal outputs.
