3. GENERAL INFORMATION ABOUT THE ACTUATOR
The Skyro 650 actuator opens and closes window sashes by means of a square
steel rack. The rack is moved by a gear reducer driven by an electric motor, which in turn is
powered and controlled by an electronic circuit board. The opening and closing movemen
is determined by the polarity of the electrical wires in accordance with the wiring carried out
(see wiring diagrams on page 14 and 15).
