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's position does not allow for an "a" value listed in the table,
the leaf's hinge pivot can be shifted (fig. 4), or a recess can be made cut out
of the actual gate-post (fig. 5).
4.4) Mounting the brackets to the gate-post and to the gate.
Fix the bracket "P" (fig. 6) to the gate-post with a good welding.
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 operates on a slope (opening inwards with an uphill driveway), fig.7
gives the maximum oscillations of the piston with respect to its horizontal.
• 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).
• WARNING!: Fixing bracket "F" must be welded before fitting the operator.
Then, with reference to Fig. 7, fully insert bush "B" in the bracket, position
spacer ring "R", insert the operator pivot and fix the pivot to the bracket
by means of ring "S".
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.
6) THE ELECTRICAL PLANT SET-UP (fig. 12).
Lay out the electrical installation (fig. 16) with reference to the CEI 64-8 and
IEC 364 provisions, complying with the HD 384 and other national standards
in force for electrical installation.
The mains power supply connections must be kept totally separate from the
service connections (photocells, electric edges, control devices etc.).
WARNING! For connection to the mains, use a multipolar cable with
a minimum of 3x1.5mm cross section and complying with the previ-
2
ously mentioned regulations. For example, if the cable is out side (in
the open), it has to be at least equal to H07RN-F, but if it is on the inside
(or outside but placed in a plastic cable cannel) it has to be or at least
egual to H05VV-F with section 3x1.5mm
Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards.
Fig.12 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.12):
I
Type-approved omnipolar circuit breaker with at least 3,5 mm contact
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 Blinker tuned in with antenna
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
For the connection from the controller to the control board, three cables have
been provided having the following functions:
• red motor +
• black motor -
• white end-of-stroke control
Fig. 16 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 - (red/black) on the control board.
The first command after an interruption of the power supply should be an

opening manoeuvre.
The cable sections and numbering are indicated in the diagram (fig. 12).
For distances of over 100 meters, the cable section must be increased.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. 13):
Bring the leaf to the required closing position, loosen the two closing limit
fixing screws (FC1 in Fig. 1) and move the limit device towards the fixing
bracket until the microswitch is heard clicking.
Carry out a closing manoeuvre to check the exact limit activation point; if the
leaf stops before the required closing point, slightly move the limit device
towards the rod end; if, on the contrary, the leaf reaches the closing ground
stop plate and the operator reverses its movement, slightly move the limit
device towards the operator body. After identifying the correct limit position,
fix the device by means of the two screws.
8.2) Opening limit device adjustment (Fig. 14):
Bring the leaf to the required opening position, loosen the two opening limit
fixing screws (FC2 in Fig. 1) and move the limit device towards the fixing
bracket until the microswitch is heard clicking.
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 identifying the correct limit
position, fix the device by means of the two screws.
N.B.When using the LIBRA control board, remember to slightly anticipate the
intervention of the limiting devices because the stem, after intercepting the
limiting devices, continues to move for a further 1-2 cm. (100 ms). In this way
a perfect strike of the leaves against the ground supports is guaranteed.
9) MANUAL OPENING
All controllers feature a key release mechanism. After lifting the lock cover
(fig.15), insert the release key supplied and turn it clockwise by 90°.
Push the leaf manually to open the gate. To reset the motorised operation,
turn the key in the opposite direction and refit the cover.
10) ELECTRIC LOCK
WARNING: In the case of leaves longer than 3m, it is
indispensable to install an electric lock.
Fig. 16 shows an example of how a 12 Va.c. ECB electric lock is to be con-
nected to a LIBRA control panel.
In order to control the electric lock, the Libra panel requires an appropriate
ME BT board.
11) CHECKING THE AUTOMATION
Before considering the automation completely operational, the following
checks must be made with great care:
• Check that all the components are firmly anchored.
• Control all the safeties work properly (i.e. photocells, pneumatic skirt, etc.).
• Check the emergency manoeuvre control.
• Check the opening and closing manoeuvres using the controls.
• Check the control unit's electronic logic in normal (or customised) opera-
tion.
12) USE OF THE AUTOMATION
Since the automation may be remote controlled either by radio or a Start
button, it is essential that all safeties are checked frequently.
Any malfunction should be corrected immediately by a qualified specialist.
Keep children at a safe distance from the field of action of the automation.
