Abstract

Un circuit de mesure dans le circuit de sortie du détecteur, par exemple, détermine la polarité du circuit utilisateur appliquée à ses bornes. L'un ou l'autre des deux états détectés est mémorisé dans une mémoire et l'étage d'attaque correct est relié aux bornes de sortie. Cet état persiste tant que la polarité au niveau des bornes de sortie ne varie pas. Si par exemple les bornes sont interchangées lors du remplacement d'un relais défectueux, le circuit de mesure corrige l'état mémorisé de sorte que l'étage d'attaque correct est également relié au circuit utilisateur. Si, par exemple, des détecteurs commutant sur (+) au lieu de (-) sont subitement nécessaires lors du remplacement d'une carte de commande ou d'une commande, il n'y a pas lieu d'interchanger les dispositifs. Ils sont initialisés (reconditionnés) lorsque la tension est commutée et adaptée aux nouvelles conditions.
