GENERAL DESCRIPTION OF THE PRODUCT
Dardo 424 is a 24 Vdc electromechanical operator for external mount on swinging gates in residential and block of flats
applications. It comes in a kit format to operate two gate leafs. Command and safety accessories for a proper performance are
included. It is a non reversible, 24 Vdc power supplied motor-operator, complete with an incorporated encoder. Stop plates are
fitted to the pressure cast aluminium body. The linear movements are by a brass shaft nut (threaded bush) and a screw shaft (rolled
thread), all supported by a radial bearing and a lubricated bushing.
In case of an electric power failure, Dardo 424 can be "released" by a custom-made, coded key and the gates moved by hand.
Terminals are factory fitted to each operator and provide connections for the power supply and the encoder to the electronic
controller Elpro 42 , to be installed stand alone, in a sheltered place.
NOTE: The Dardo operators are not handed units and therefore they come all alike both for the right and the left gates: following
their respective connections to the Elpro 42 controller, they are identified as Dardo M1 (first gate to open and pedestriam mode)
and Dardo M2 (gate delayed on opening) (Pic.3).
Dardo does not come fitted with electronic limit switches as they are not necessary, limit stop positions are learned by the system
in phase of programming as determined by the incorporated stop plates.

PRODUCT APPLICATIONS
The table below shows the maximum dimensions of a gate leaf in relation to its maximum weight.
Max. width per leaf L (m)
Max. weight per leaf P (kg)
NOTE: the gate structure should not be fully panelled without openings, avoid that in-filling is more than 50% of the gate surface.
