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.
