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 (1) and with at least one control and evaluation unit (2), the monitoring and detection devices (1) being series-connected to one another and to the control and evaluation unit (2) 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 (1) has several different influence areas (3) and several signal outputs.

L'invention concerne un circuit servant à contrôler que l'état d'une installation du type téléphérique ou télésiège est correct et/ou à reconnaître un état incorrect d'une telle installation. Ce circuit comporte une pluralité de dispositifs de surveillance et de reconnaissance (1) et au moins une unité de commande et d'évaluation (2). Les dispositifs de surveillance et de reconnaissance (1) sont connectés en série les uns avec les autres et avec l'unité de commande et d'évaluation (2) et peuvent être interrogés en ce qui concerne leur état, en particulier en ce qui concerne leur état de commutation. Afin qu'un tel circuit puisse satisfaire aux exigences de sécurité les plus hautes tout en ne présentant qu'un faible encombrement, chaque dispositif de surveillance et de commutation (1) présente plusieurs zones d'influence (3) différentes et plusieurs sorties de signal.
