Abstract

Lorsqu'un signal de commande d'arrêt est envoyé à un dispositif électrique dans lequel une coupure de courant efface et annule les conditions de fonctionnement prédéfinies, le fonctionnement de la charge du dispositif électrique est arrêté alors que la puissance est envoyée à un circuit dans lequel sont stockées les conditions de fonctionnement. Etant donné que le fonctionnement de la charge est arrêté en réponse au signal de commande d'arrêt, la puissance de travail peut être réduite. De plus, étant donné que la puissance est envoyée au circuit dans lequel les conditions de fonctionnement sont stockées, les conditions de fonctionnement ne sont pas effacées et le fonctionnement se poursuit, conformément aux conditions de fonctionnement lorsque l'opération est relancée. Lorsqu'un signal de commande d'arrêt est envoyé à un dispositif électrique, pendant une coupure de courant, le dispositif électrique se place dans un état d'attente, et, lorsque la puissance est à nouveau distribuée après la coupure de courant, la puissance est à nouveau fournie et un signal de commande de fonctionnement est produit. Le fait de fournir à nouveau de la puissance lorsque le signal de commande de fonctionnement est produit a pour effet de placer le dispositif électrique dans un état d'attente et le fait d'appliquer le signal de commande de fonctionnement a pour effet de faire fonctionner le dispositif qui se trouvait jusqu'alors en état d'attente.
