摘要： An apparatus (1) for moving a closing barrier, in particular for moving a door or gate, comprises:
- a control station (10) for controlling the movement apparatus, said control station (10) comprising a supply circuit (100) for supplying a PWM supply voltage to a two-wire communication and supply bus (B) coupled to said control station (10); and
- at least one utilizer device (12) that uses said PWM supply voltage and is coupled to said two-wire communication bus (B), said utilizer device (12) comprising a conversion circuit (120) for converting said PWM supply voltage into a supply current for an electric motor (122) for movement of said closing barrier.
The control station (10) comprises an amplitude-modulation circuit (102) for transmitting an amplitude-modulated data communication signal superimposed on said PWM supply voltage onto said communication and supply bus (B), and the at least one utilizer device (12) that uses said PWM supply voltage is coupled to a circuit (124) for amplitude demodulation of said amplitude-modulated data communication signal for receiving signals from said communication and supply bus (B).

摘要： Operating system for a sectional door (1) comprising a gear motor (6) housed in a box (13) with flattened configuration suitable to be positioned adjacent to the horizontal shaft (7) on which there are wound torsion springs for the balancing of the sectional door (1), substantially at the same level as such horizontal shaft (7). The drive carrier (4) of the sectional door (1) may be configured to be connected to the upper panel (2) of the door selectively at one end thereof or at the opposite end, and the guide (5) of the carrier (4) can be installed in two mutually alternative positions rotated by 180°.
