Abstract

Nouveaux systèmes permettant de tester des fermetures ou des barrières de protection utilisées sur des machines dangereuses en vue de protéger le personnel. Les protections sont vérifiées séparément ou bien en conjonction avec des dispositifs de sécurité qui peuvent comprendre des mécanismes de verrouillage, de blocage et des dispositifs d'enclenchement. La procédure de test se déroule sans qu'il soit nécessaire d'arrêter la machine sur laquelle est monté le système de protection. Des dispositifs de vérification sont introduits dans la procédure pour établir l'intégrité des dispositifs de sécurité et pour effectuer des tests automatiques. Cette invention concerne également plusieurs dispositifs nouveaux qui sont mis en oeuvre dans ces systèmes.
