higher differences cause great speed variations during the gate
opening and closing movement.
Keep a
Z
dimension in such a way that the operator does not
strike the pillar.
c
in the LS versions the limit switches are triggered for the first and
the last 30 mm.
Therefore use such A and B dimensions in order to
use the whole operator travel. Shorter travels could limit or cancel
the limit switch adjustment range
.
If the pillar dimensions or the hinge position do not allow the
installation of the operator, a niche on the pillar, as shown in
Fig. 5, should be created in order to maintain the A dimension
as determined. The niche should be dimensioned in such
a way to enable easy installation, operator rotation and
operation of the release device.
3.4. INSTALLING THE OPERATORS
Fix the rear bracket in the position determined before. In the
event of iron pillar carefully weld the bracket directly on the
pillar (Fig.6). In the event of masonry pillar, use the suitable
plate (optional) for the fixing to screw (Fig.7) by making use
of suitable fastening systems. Then carefully weld the bracket
to the plate.
During the fastening operations, check if the bracket is
perfectly horizontal by means of a level.
Assemble the rear fitting to the operator as shown in Fig.8.
Set the operator for manual operation (see paragraph 5)
Completely extend the rod till it reaches the limit stop, fig.9
ref.
a
.
Lock the operator again (see paragraph 5.1)
Turn the rod clockwise half a revolution / a revolution, Fig.9
ref.
b
.
Assemble the front bracket as shown in Fig.10.
Fix the operator to the rear bracket by means of the supplied
pins as shown in Fig.11.
Close the leaf and, keeping the operator in a perfect horizontal
position, determine the fastening point of the front bracket
(Fig.12).
Temporarily fix the front bracket with two welding spots
(Fig.12).
If the gate structure does not allow a fix bracket fastening it
is necessary to create a sturdy supporting base in the gate
structure.
Release the operator (see paragraph 5) and manually check
if the gate can completely open without hindrances and stop
at the mechanical travel stops as well as if the leaf moves
regularly without any friction.
Carry out the necessary corrective measures and repeat from
point 8.
Temporarily release the operator from the front bracket and
weld the bracket definitively.
If the leaf structure does not allow a bracket welding, the
suitable bracket to screw (optional) can be used together
with suitable fastening systems (Fig.13). Then carry out the
same operations as prescribed for the bracket to weld
.
We recommend to grease all the fastening pins of the fittin-
gs
.
3.5. WIRING THE OPERATOR
A terminal board is fitted in the lower part of the operator for the
connection of the motor, of any limit switch and for the earthing
of the operator.
For the connections should be usable a sheathed cable sui-
table for mobile installation outdoor.
Motor wiring operations:
Open one of the two pre-drilled holes in the supplied cover,
Fig.14; in case of operators with limit switches, open both
holes.
Fit the supplied cable gland.
Connect the motor and the earthing with reference to Fig.15
and the following tables.

Close the cover with the four supplied screws, Fig.16.
3.6. LIMIT SWITCHES
“
LS
” models are equipped with opening and closing limit switches.
Therefore they require the use of a control board able to control
these inputs.
Limit switches are triggered for the first and the last 30 mm
of the travel. Therefore the operator should use the whole
available travel during the opening phase. Shorter travels
can limit or completely cancel the limit switch adjustment
range.

Limit switches are wired in the same terminal board where the motor
wiring has been carried out. Wire the limit switches as follows:
Open the second pre-drilled hole in the cover, Fig.17.
Fit the supplied cable gland, Fig.17.
Insert the cable and connect it to the terminals observing the
colours specified in the following table (with redo Figure 18).

,
togliere l’alimentazione elettrica.
Carefully observe points 10, 11, 12, 13 and 14 of the SAFETY GE-
NERAL RULES.
With reference to the indications in Fig.3, set the ducts and carry
out the electrical connections of the control board and of the
chosen accessories.
Always separate power cables from control and safety cables
(push button, receiver, photocells, etc.). To avoid any electrical
noise whatever in the unit, use separate sheaths.
