Beschreibung
Zusammenfassung:	Apparatus (10) for use with barrier movement systems (16) in which a flexible member (26, 26') is used to move or support the barrier. The apparatus measures tension in the flexible member and generates a signal when the tension eases beyond a predetermined point. Additionally, the apparatus includes a stop member (83) which moves in response to easing tension to a position to stop further barrier movement. L'invention concerne un appareil à utiliser avec des systèmes d'actionnement de barrière, dans lequel un élément souple est utilisé pour l'actionnement ou le soutien de la barrière. Ledit appareil mesure la tension dans l'élément souple et génère un signal lorsque la tension se relâche au-delà d'un point prédéterminé. De plus, ledit appareil comporte un élément d'arrêt qui se déplace en réaction au relâchement de tension, de sorte qu'il soit mis dans une position empêchant la barrière de bouger.
