Method&#x2014;and device for the implementation thereof intended to provide a protection system for barriers which are movable along an operating path and actuated by a motor, such as roller blinds, gates or the like, comprising the steps of connecting the barrier, with play, to a fixed part () so that the barrier is able to move independently of the action of the motor over a travel section (); defining within the section () a set of safety positions corresponding to a safety position for the barrier; detecting along the travel section () the actual position of the barrier with respect to the fixed part (); preventing or reversing the action of the motor and/or the movement of the barrier when the barrier, inside the travel section (), does not have a position included within the set of safety positions.

Safety device for roller blinds, sun, awnings, gates or the like

Method for controlling a signalling device inserted in an automatism of gates (G), movable barriers, doors or the like, and having at least one warning device (L, BZ), characterized in that it supplies power from the signalling device (LL) to at least one mechanical group (M) having a motor, detects in the signalling device (LL) the absorbed power from the at least one mechanical group (M) having a motor, and activates the at least one warning device (L, BZ) when the predefined absorbed power threshold has been exceeded.

Signaling device and method of controlling the device

An electrical control safety system is provided comprising two photocells or equivalent sensors applied on a sliding gate, the two photocell systems being composed respectively of at least two transmitters and two receivers, and the control safety system being cyclically able to make the first photocell system operate during a first operating time interval while the second photocell system is disabled, and being cyclically able to make the second photocell system operate, during a second operating time interval, subsequent to the first time interval, while the first photocell system is disabled.

Electrical control safety system comprising photocells or equivalent sensors

An electrical system for controlling at least one gate or door or similar element of the type moved by means of at least one corresponding electric motor includes an electric network (NTWRK) consisting of two electric wires adapted to allow the distribution of direct-current power supply and digital information, a central control unit (UC) having two terminals (T,T) adapted to be connected respectively but indifferently to the two wires of the network (NTWRK) in order to transmit direct-current power supply and to transmit and receive digital information, a certain number of peripheral units (UP), each having two terminals (T,T) adapted to be connected respectively but indifferently to the two wires of the network (NTWRK) in order to receive direct-current power supply and to receive and/or transmit digital information.
