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).
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 previously
2
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 .
2
Connect the control and safety devices in compliance with the previously men-
tioned 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 3mm contact ope-
ning, 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.
SPL
Heater board for operation at temperatures below 10°C (optional)
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 LOG-GK 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 ope-
ning 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) ADJUSTMENT OF THE LIMITING DEVICES
The correct adjustment of the limiting devices is obtained by positioning the
end-of-stroke magnets correctly (FC1 and FC2 in Fig.1) with respect to the axis
of the front bracket. Loosen the fastening screws of the magnets as described
in the following paragraphs so that they can slide inside the end-of-stroke track
"B" (Fig.1).
8.1) Adjustment of the closing limiting devices (Fig.13):
Move the leaf to the desired closing point, loosen the two screws A and B of the
closing limiting device (FC1 in Fig.1) and move it so that the distance between
the screw B and the axis of the front racket is 376 mm approximately (as shown
in fig. 13).
Perform a closing manoeuvre to make sure that the end-of-stroke limiting device
operates correctly; if the leaf stops too far before the desired closing point, slightly
move the limiting device towards the end of the stem; if, on the contrary, the leaf
hits the ground closing stopping device and the actuator reverses its moving
direction, move the end-of-stroke limiting device slightly towards the actuator
body. After identifying the correct position of the limiting device , fix it using the
two screws A and B.
8.2) Adjustment of the opening limiting devices (Fig.14):
Move the leaf to the desired opening position, loosen the two screws C and D
of the opening limiting device (FC2 in Fig.1) and move it so that the distance
between the screw D and the axis of the front bracket is 376 mm approximately
(as shown in fig. 14).
Perform an opening manoeuvre to make sure that the end-of-stroke limiting de-
vice operates correctly; if the leaf stops too far before the desired opening point,
slightly move the limiting device towards the actuator body; if, on the contrary,
the leaf hits the ground closing stopping device and the actuator reverses its
moving direction, move the end-of-stroke limiting device slightly towards the
end of the stem. After identifying the correct position of the limiting device , fix
it using the two screws C and D.
N.B. When using the LOG-GK 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) COVErS
An is available in order to protect the stem and to improve the appearance of
the actuator.
The stem cover is mounted on the right or left actuator by simply inverting the
position of the cover and making sure that the water drain outlet is directed
downwards (fig. 17).
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.
