(FR) MÉCANISME DE VERROUILLAGE DE SÉCURITÉ
Abstract:
(EN) It is disclosed a safety interlock mechanism that comprises: a plurality of interlock switches having a first contact and a second contact; an actuator mechanically coupled to each interlock switch, the actuator having an active position wherein the actuator acts on the switch so that the first contact is in conductive state and having a passive position wherein the actuator acts on the switch so that the second contact is in conductive state; and a detection circuit connected one of the interlock switches; wherein the plurality of interlock switches are connected in series through the first contact and the detection circuit is connected to the second contact being the detection circuit an active circuit to determine the position of the actuator.
(FR) L'invention concerne un mécanisme de verrouillage de sécurité qui comprend : une pluralité de commutateurs de verrouillage ayant un premier contact et un second contact ; un actionneur accouplé mécaniquement à chaque commutateur de verrouillage, l'actionneur ayant une position active, l'actionneur agissant sur le commutateur de sorte que le premier contact soit dans un état conducteur et ayant une position passive, l'actionneur agissant sur le commutateur de sorte que le second contact soit dans un état conducteur ; et un circuit de détection connecté à l'un des commutateurs de verrouillage ; la pluralité de commutateurs de verrouillage étant connectés en série par l'intermédiaire du premier contact et le circuit de détection étant connecté au second contact étant le circuit de détection d'un circuit actif pour déterminer la position de l'actionneur.
