Title (EN) NONVOLATILE STATUS INDICATOR SWITCH
(FR) INTERRUPTEUR INDICATEUR D'ÉTAT NON VOLATIL
Abstract:
(EN) A non-volatile status indicator switch is provided. In one embodiment, the invention relates to an aircraft electrical system including a fault detection circuit coupled to a relay, and a fault indicator circuit coupled to the fault detection circuit and to a control input of the relay, wherein the fault indicator circuit includes a nonvolatile memory element, wherein the fault detection circuit is configured to detect a fault and to provide a signal indicative of the fault to the fault indicator circuit, and wherein the fault indicator circuit is configured to respond to the signal indicative of the fault by providing a predetermined control signal to the relay and by storing information indicative of the detection of the fault in the nonvolatile memory element.
(FR) L'invention concerne un interrupteur indicateur d'état non volatile. Selon un mode de réalisation, l'invention concerne un système électrique d'aéronef comportant un circuit détecteur d'anomalie couplé à un relais, et un circuit indicateur d'anomalie couplé au circuit détecteur d'anomalie et à une entrée de commande du relais, le circuit indicateur d'anomalie comportant un élément mémoire non volatile, le circuit détecteur d'anomalie étant configuré pour détecter une anomalie et pour fournir au circuit indicateur d'anomalie un signal indiquant l'anomalie, et le circuit indicateur d'anomalie étant configuré pour réagir au signal indiquant l'anomalie en fournissant au relais un signal de commande prédéfini et en mémorisant dans l'élément mémoire non volatile des informations indiquant la détection de l'anomalie.
