4) INSTALLATION OF THE ACTUATOR

4.1) Preliminary checks

Check that:
• The gate structure is sufficiently sturdy.
• Also make sure that the actuator pushes against the leaf reinforced section.
• The leaves move manually and without effort all along their stroke.
• The door stop plates are fitted at the end of both closing and opening
strokes.
• If the gate has not been recently installed, check the wear condition of all
components.
• Repair or replace faulty or worn parts.
The automation reliability and safety are directly influenced by the state
of the gate structure.
WARNING: Remember that motor drive facilitates the use of the gate,
but does not solve the problems due to faults and defects in the instal-
lation or failure to maintain the gate itself.
Fix the "Warning" sign provided (Fig. 12) on both sides of the gate.
The diagram in fig. 2 should be used as a reference for installation and
consult the table for the distances in mounting the gate post.
The diagram in fig. 2 uses the following legend:
P Gate post rear fastening bracket
F Front leaf fastening fork
a-b "P" bracket installation value
C Distance between fixing points (C = 14.8" (993 mm))
D Gate length
X Distance from gate axis to the edge of the post
Z Always over 1.77" (45 mm) (b - X)
kg max. weight of leaf
leaf opening in degrees
α°
4.2) How to read the installation distance tables
Select "a" and "b" according to the angle in degrees α° that the gate has to
open. The table shows the ideal value for "a" and "b" for an opening of α° =
90° at constant speed.
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.
When "a" and "b" are at their maximum, the piston develops the maximum
force.

INSTALLATION MANUAL
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 fork "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).
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).
For the electrical installation are the "Canadian Electrical Code PART I"
for Canada and the "National Electrical Code (NFPA 70)" for the United
States.
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 power supply (120V, 60Hz), perma-
nent wiring is to be employed as required by local codes. Supply conductors
(120V, 60Hz) and the main ground conductor should be contained in ap-
proved flexible watertight conduit and be at least size N. 16 AWG. Ground
Terminal: make sure the main ground conductor is connected to the ground
terminal (See Fig.3 in the LIBRA-UL-R User's and Installation Manual for
further information).
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 328 ft (100 metres); in case
of longer cables, calculate the cross section for the true automation load.
When the auxiliary connections exceed 165 ft (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 0,13" (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.

RG58 Antenna cable
For the connection from the controller to the control board, three cables have
been provided having the following functions:
• green
• black
• white
Fig. 16 shows the wiring diagram of the LIBRA UL R control unit.
Should the opening or closing direction be incorrect, it is possible to invert
the connections of motor + and motor - (green/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 328ft (100 meters), the cable section must be in-
creased. All metal masses in the housings of equipment and automation
must be earthed.
7) ADJUSTING THE PUSHING FORCE
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
