Abstract

a. Installation indicatrice d'un état de fonctionnement, notamment pour contrôler le travail à effectuer sur une ligne de fabrication. b. Installation caractérisée en ce qu'elle comporte un moyen pour émettre un signal de sortie commençant à l'exécution du travail, un moyen pour choisir un intervalle de temps d'entretien prédéterminé le travail, qu'il faut effectuer en fonction du signal de sortie, moyen donnant un signal d'entrée à la fin du travail et un moyen répondant au signal d'entrée pour donner un signal d'état d'alerte d'entretien si le signal d'entrée n'est pas fourni dans l'intervalle de temps d'entretien prédéterminé c. L'invention s'applique au contrôle de procédés industriels quelconques.
