Electromechanical automation for spring-operated overhead doors. Control unit with self-learning and self-diagnostic functions. Encoder-type limit switch without references in the chain. Control unit compatible with the EElink protocol. Specially designed for simpler and faster installation in compliance with the safety standards laid down by the Machinery Directive. Thanks to the antisquashing system, the operator inverts motion and prevents damage to people and property in the event of contact (BT). The limit switch with integrated encoder allows the maximum stopping precision. No mechanical component of the limit switch system is subject to wear and maintenance. The strength of the track provides greater resistance to stress during assembly and in operation. The track can be fixed directly to the ceiling without using brackets. The cables are housed inside two grooves formed in the track itself. Working stroke recovery possibility by rotating the motor head 90°.
