CA 2248053

An injection device has signal generators (11, 12, 13, 14) which are connected to operative elements (8, 3, 5, 4) of the device and which give off signals which represents the operative condition of the device. The signals are sent to an electronic circuit which controls a presentation of the operational condition of the device and presents operational conditions, which are defined as not allowed, as error indications by switching off the display presenting the operational condition of the device. The number of signals from each generator is counted and a number of operations exceeding a pre-set number for the signal generator in question is interpreted as representing a not allowed operational condition.

Ce dispositif d'injection comprend des générateurs de signaux (11, 12, 13, 14) connectés à des éléments fonctionnels (8, 3, 5, 4) du dispositif et qui produisent des signaux représentant l'état de fonctionnement du dispositif. Ces signaux sont envoyés à un circuit électronique qui commande une indication de l'état de fonctionnement du dispositif et qui indique des états de fonctionnements définis comme non autorisés sous forme d'indications d'erreurs en désactivant l'affichage présentant l'état de fonctionnement du dispositif. Le nombre de signaux provenant de chaque générateur est compté, et un nombre d'opérations dépassant un nombre préétabli pour ce générateur de signaux est interprété comme représentant un état de fonctionnement non autorisé.
