520 / 600RF
520 / 700RF
Systems for remote automation of windows.
ELEMENTS OF THE SYSTEM:
1- Gear motor unit
2- Limit stop device
3- Rotary shaft
4- Shaft support bracket
5- Rack rail
6- Frame mount
with spring compensator
The new 520/600RF and 520/700RF systems have been designed to solve the problems represented by remotely opening and closing bottom-hinged or outwardopening windows, whether installed individually or in rows, also in long rows of windows, skylights, in breeding farms or greenhouses.
The windows are opened and closed by a series of rack rails running on a toothed sprocket, driven by a shaft, which in turn is turned by a gear unit.
The transmission of the rotational movement from the gear unit to the shaft, and from each element to the next on the shaft is guaranteed by joints with bolts and coupling pin.
The spring compensator on the end of the rack may be of the pulling or pushing type depending on which way the windows close, and guarantees even pressure on the window frames.
The rotary shaft support brackets run on ball bearings and have adjustment slots. They can also be fitted with counterbrackets. Available for shafts with diameters of 27-33-42 mm.
The rack rails feature brass toothed sprockets, which must be fixed to the rotary shaft using the relevant press-fit bolts.
The bracket, to screw onto the window, is held on the rack with a practical spring-loaded pin.
Electrical gear unit with single-phase motor coupled to a self-locking worm screw gear unit. With limit stop.
520 SERIES MOTOR
The 520 series motors have a three-phase motor coupled to a steel self-locking worm screw gear unit with bronze machinedfrom- solid gears in a cast iron selflubricated casing. The low-speed shaft has two protuberances with holes and a slot on both ends, so that it can be positioned in the centre or at one end of the gear unit. 520/700RF Motor The rotary limit stops are fast-acting and adjustable, and are fitted on one of the two hubs of the low-speed shaft, with an aluminium protective cover.

A curved rack can be supplied, in order to reduce the inward projection in the presence of obstacles or in case of window frames with limited height from the ground.

* Maximum overall load at 18° C.
N.B.: The number of racks to fit on each window must be calculated by taking into consideration the necessary thrust and the dimensions and stiffness of the frame itself.
N.B.: Racks with different lengths are available on demand.
