gEnErAL InForMAtIon
Of rugged construction, with an innovative and pleasant
design, the road barriers EVA are suited for intensive use
thanks to their 24VDC motor. This system is very easy to
install and adjust.
Equipped with an easy-to-use manual release, the barrier is
preset to assemble buffer batteries to allow its operation in
the event of power failure.
The arm in paint aluminium allows for the housing of any
accessories, as well as forewarning and safety devices. In
the event the arm hits an obstacle, an amperometric sensor
causes the movement reversion immediately.
The control unit is placed on the upper side of the barrier to
facilitate wire connections.

DIMEnSIonS
Overall dimensions are expressed in mm.
The road barrier length ranges from 5m to 7m maximum.
As about 30cm are required to fix the road barrier, a useful
opening of passage, ranging from 2.70m to 6.70m, will be
available, as shown in Fig.1
Optional accessories can be fitted onto be barrier (photo-
cells, selector, etc.). For assembly, apply the special covers
supplied (Ref. A).

A right-hand opening road barrier is a system which, seen
from the door side, closes the right-hand side of the passage.
The left-hand opening is in the opposite way. The EVA 7 road
barrier is normally supplied as right-hand opening road barrier
(EVA7-DX). In any case, with a few, simple operations, the
opening side can be changed (EVA7-SX). The procedure is
described in paragraph "Presetting of right-left hand opening
of the barrier".
oPEnIng
The access to the electric and mechanical components of
the road barrier is protected by a lock with customized key.
Proceed as follows:
1 loosen the two nuts D
2 introduce the key in the lock on the side of the door and
turn it anti-clockwise
3 lift the front cover
4 remove the cover
By removing the front door it is now possible to reach both
the control unit, that is placed under the cover, and the me-
chanical parts of the road barrier.

AnD ACCESSorIES
Before tensioning the spring, the type of spring to be used
must be chosen.
two types of springs can be selected, which are different
in length: a short spring (364mm - EVA.KM)) and a long
one (480 mm - standard).
In Table , see the type of springs required according to the
length of the beam and the use of accessories.
2 springs, 480mm long, which can be used in most types
of installations, are factory supplied.
A 360mm long spring is not supplied with the system and
it will be therefore necessary to buy it.
The table hereunder shows the indicative tensioning value
(expressed in mm); for a correct balancing of the road beam,
see section "Balancing".
