CA 2343128

The subject invention is directed to methods, processes and decisions on test outcomes for testing for faulty, therefor dangerous, performance of zero speed indicators (16) that are used to control the opening of barriers guarding moving machine components (17). The indicators (16) may be tested by removing them from the components (17) during operation without shutting down production or in certain situations the indicators (16) may be tested during the run down phase of the components caused by machine stop initiations. The tests allow to anticipate and hence prevent hazardous opening of barriers due to a faulty zero speed indication. Additionally, the invention is directed to testing of the insertion of motion interference devices in conjunction with zero speed indicators, both of which must perform correctly in order to permit the unlocking and opening of the protective barrier. There are included various exemplary devices for effecting the testing function.

L'invention concerne des procédés, procédures et décisions concernant les résultats de la recherche de performances erronées, et donc dangereuses, de détecteurs de vitesse nulle utilisés pour commander l'ouverture de barrières protégeant contre des éléments mobiles de machines. On peut tester ces détecteurs en les enlevant des éléments pendant le fonctionnement sans arrêter la production. Dans certaines situations, on peut les tester pendant la phase de décélération d'éléments due au déclenchement d'arrêts de machines. Ces tests permettent d'anticiper et, donc, d'empêcher l'ouverture dangereuse de barrières résultant d'une indication erronée de vitesse nulle. Dans les procédés selon l'invention, on teste également l'insertion de dispositifs d'interférence de mouvement en liaison avec des détecteurs de vitesse nulle, les deux devant fonctionner correctement afin de permettre le débloquage et l'ouverture de la barrière de protection. L'invention inclut divers modèles de dispositifs pour effectuer la fonction de test.
