In an elevator safety device, a brake device puts brakes to brake a car through an operation of a safety relay main contact provided to a safety circuit. When the car stops during normal operations, a safety relay instruction signal for operating the relay main contact to such a direction that the brake device puts brakes is generated from a detection circuit. Then, the detection circuit detects whether or not the safety relay main contact is operated in accordance with the safety relay instruction signal.
Dispositif de sécurité d'ascenseur dans lequel un frein est actionné par l'action du contact principal d'un relais de sécurité installé dans un circuit de sécurité pour freiner une cage. Quand la cage est arrêtée en fonctionnement normal, un circuit de détection génère un signal de commande de relais de sécurité servant à actionner le contact principal du relais de sécurité dans le sens de l'actionnement du frein. Le circuit de détection détecte si le contact principal du relais de sécurité a fonctionné en réponse au signal de commande du relais de sécurité ou non.
