appropriate objects to test the correct functionality of the
safety accessories, such as photocells, sensitive edges, etc. □
Carry out a risk analysis by means of appropriate instruments
measuring the crushing and impact force of the main opening
and closing edge in compliance with EN 12445. □ Identify the
appropriate solution necessary to eliminate and reduce such
risks. □ In case where the gate to automate is equipped with a
pedestrian entrance, it is appropriate to prepare the system in
such a way to prohibit the operation of the engine when the
pedestrian entrance is used. □ Apply safety nameplates with CE
marking on the gate warning about the presence of an
automated installation. □ The installer must inform and instruct
the end user about the proper use of the system by releasing
him a technical dossier, including: layout and components of
the installation, risk analysis, verication of safety accessories,
verication of impact forces and reporting of residual risks.

CE DECLARATION OF CONFORMITY of the manufacturer:
Meccanica Fadini snc (Via Mantova, 177/A - 37053 Cerea - VR - Italy) declares under own responsibility that: Dardo 424 complies
with the 2006/42/CE Machinery Directive, and also that it is sold to be installed in an “automatic system”, along with original
accessories and components as indicated by the manufacturing company. An automatic gate operator is, by law, a “machinery”
and therefore the installer must t the equipment with all of the applicable safety norms. The installer is also required to issue
the installer’s Declaration of Conformity. The manufacturer is not liable for possible incorrect use of the product. The product
complies with the following specic norms: analysis of the risks and subsequent action to cure them as per EN 12445 and
EN 12453, Low Voltage Directive 2014/35/UE, Electromagnetic Compatibility 2014/30/UE. In order to certify the product, the
manufacturer declares under own responsibility the compliance with the EN 13241-1 PRODUCT NORMS.
This product complies with the following norms:
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.
Pic. 1 displays all of the components that are delivered for the installation of each Dardo operator.
