摘要:
The invention concerns a safety device for power operated closing systems, such as industrial, commercial, garage, gate electromechanical systems and similar, where the closing system has at least one moving part driven by an electric motor using mains supply voltage and frequency current, governed by an electronic control panel. As a safety measure, the device makes us of an encoder or an encoder and inverter in combination, to generate signals to the electronic panel indicating the position and speed of the moving part so as to control and limit the dynamic or impact force of the latter on encountering an obstacle during its travel.
