4.2) How to read the installation distance tables (Fig.2)
Select "a" and "b" according to the angle in degrees α° that the gate has to
open. The optimum "a" and "b" values for 92° opening at constant speed
are highlighted.
If there is too large a difference between "a" and "b", the leaf will not travel
smoothly and the pushing or pulling force will fluctuate during its stroke.
To respect the opening speed and ensure the controller operates correctly,
it is best to keep the difference between "a" and "b" as low as possible.
The table has been worked out for a 20-mm thick medium-size gate.
Always check that there is no possible collision between the gate and
the operator.
4.3) Off-standard installations.
Fig. 3 shows an installation with a recess when there is not sufficient
space between the leaf and perimeter wall.
When the leaf position does not provide for a value of "b" present in the
table, change the length of the bracket or make a recess in the gate-post
(Fig. 5).
4.4) Anchoring the attachments to the gate-post.
Fix the bracket "P" (fig. 6) to the gate-post with a good welding.
In the same way, weld the "F" bracket to the gate (or fix it with 4 M8 screws),
making sure that the operator to be fitted is positioned parallel with the gate
movement plane, fig.7. The bracket "F" should be welded in the same way
to the gate taking care that the actuator can then be mounted perfectly
horizontal to the line of travel of the gate fig. 7.
• If the gate-post is in brick, the plate "PF" must be set soundly into the post
using adequately sized cramps "Z" welded to the back of the plate (fig.
8).
• If the gate-port is in stone and the gate is small, the plate "PF" can be
mounted with four metal expansion plugs "T" (fig. 9). If a larger gate is
being installed it would be better to use a corner plate "PF" (fig. 10).
Fit the rear bracket pin as in Fig.6.
4.5) Anchoring the attachments to the gate leaf.
Fixing bracket "F" must be fixed at a distance of 700 mm from attach-
ment P in Fig.6.
IMPORTANT: the front bracket must be fitted with the bush collar
protruding UPWARDS (Fig.4 Ref.A).
4.6) Power supply cable (Fig.12)
The board power supply cable must be of the H 05 RN-F type or equiva-
lent. The equivalent cable must guarantee:
- permanent outside use
- rated voltage of 300/500 V
- maximum temperature on the cable surface of +50° C
- minimum temperature of -25° C
Moreover, it must have a minimum section of 3 x 1.5 mm2 and, for the
cable to hold correctly, it must be provided with an external sheath of Ø
= 7.1 to 9.6 mm. Insert the cable into O ring "K" (Fig.12), strip it by about
40 mm and connect the cables to the terminal bar (see diagram S).
Position the cable sheath so that O ring "K" is inserted in its housing in
the base and, leaving the sheath protrude by about J=5 mm (as shown
in Fig.12), close the hatch and fix it by means of the 3 screws.
4.7) Operator fitting
Position the operator on the brackets and fix everything as indicated in
Fig. 6 and 7.
In the case of gates moving over a slope (opening towards the inside
with an upward sloping driveway), the operator allows the gate to oscil-
late with respect to the horizontal axis, for the maximum values indicated
in fig.7.
5) GROUND GATE STOPS
For the controller to operate correctly the gate stop "B" must be used both
in opening and closing, as shown in fig. 11.

INSTALLATION MANUAL
6) THE ELECTRICAL PLANT SET-UP (fig. 13).
Lay out the electrical installation (fig. 13) with reference in force for elec-
trical installation.
The mains power supply connections must be kept totally separate from the
service connections (photocells, electric edges, control devices etc.).
Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards.
Fig.13 shows the number of connections and the cross section for power
supply cables having a length of approximately 100 metres; in case of
longer cables, calculate the cross section for the true automation load.
When the auxiliary connections exceed 50-metre lengths or go through
critical disturbance areas, it is recommended to decouple the control and
safety devices by means of suitable relays.
The main automation components are (fig.13):
I Type-approved omnipolar circuit breaker with at least 3,5 mm con-
tact opening, provided with protection against overloads and short
circuits, suitable for cutting out automation from the mains. If not
already installed, place a type-approved differential switch with a
0.03A threshold in the circuit just before the automation system.
Qr Control panel and incorporated receiver.
S Key selector
AL

M Controller
Fte Pair of outside photocells (transmitters)
Fre Pair of outside photocells (receivers)
Fti Pair of inside photocells with column (transmitters)
Fri Pair of inside photocells with column (receivers)
T 1-2-4 channel transmitter
RG58 Antenna cable
The connection between the operator and the control panel should be
carried out using three cables, identified as follows:
Fig. 17 shows the wiring diagram of the LIBRA control unit.
Should the opening or closing direction be incorrect, it is possible to invert
the connections of motor + and motor - on the control board.
The first command after an interruption of the power supply should be
an opening manoeuvre.
All metal masses in the housings of equipment and automation must be
earthed.
7) ADJUSTING THE PUSHING FORCE
WARNING: Check that the impact force value measured at the
points established by the EN 12445 standard is lower than that
specified in the EN 12453 standard.
The pushing force is calibrated by means of the torque regulator in the
control unit. The optimum torque must allow a complete opening or closing
cycle with the minimum force necessary. An excessive torque can reduce
the anti-crush safety. In the other case, an insufficient torque can impede
the manoeuvres. Consult the control unit's instruction manual.
8) LIMIT DEVICE ADJUSTMENT
End-of-stroke adjustment is carried out by correctly positioning the limit
devices (FC1 and FC2 in Fig. 1).
8.1) Closing limit device adjustment (Fig. 14):
Carry out a closing manoeuvre to check that limit device activation is
correct; if the leaf stops before the required closing position, slightly
move the limit device towards the head cap; if, on the contrary, the leaf
meets the ground closing stop and the operator starts to reverse, slightly
move the limit device towards the operator body. After completing the
adjustment, fix screw A.
ATTENTION! To avoid braking the limit switch cable, tighten screw A
keeping the wire B well tightened (as shown in Fig.14A).
8.2) Opening limit device adjustment (Fig. 15):
Carry out an opening manoeuvre to check the exact limit activation point;
if the leaf stops before the required opening point, slightly move the limit
device towards the operator body; if, on the contrary, the leaf reaches
the opening ground stop plate and the operator reverses its movement,
slightly move the limit device towards the rod end. After completing the
adjustment, fix screw A.
N.B. When using the LIBRA control board, remember to slightly anticipate
the intervention of the limiting devices because the stem, after intercepting
