Abstract

Actuating system for roller shutters, sliding barriers or the like, comprising a rotational sensor for controlling and/ or measuring the relative angular position of a shaft or a rotating spindle able to generate a signal with a number of pulses proportional to the angle moved dirough, characterized in that the sensor comprises means for generating a reference pulse every predefined number of pulses of said signal.
