INSTALLATION

3.1 - Pre-installation checks

Before going ahead with the installation, check the integrity of the product com-
ponents, and ensure the model chosen is suitable for its intended use and for
the environment in which it is to be installed.
• Check that all the material to be used is in excellent condition and suitable for
its intended use.
• Check that the ground-mounted mechanical stops (not supplied), are present
both when opening and closing the automation system.
• Check that the mechanical structure of the gate is suitable for the installation
of automation and compliant with locally applicable regulations (if necessary,
refer to the label on the gate). This product cannot be used to automate a gate
which is not already in good, safe working order, neither can it fix faults caused
by incorrect installation or poor maintenance of the gate.
• Check that the operating conditions of the devices are compatible with the
usage limitation declared (see paragraph 3.2).
• Move the gate leaves manually in both directions and ensure that the resist-
ance to movement is constant at all points of travel (there should not be any
points where more force or less is required).
• Bring the gate leaves manually into a position at random, then let go and check
that they remain stationary.
• Check that the gearmotor fixing zone is compatible with its overall dimensions
(fig. 1).
• Check that the place where the gearmotor is to be installed allows enough
space for its arm to execute its full range of movement (fig. 2).
• Check that there is sufficient room around the gearmotor for it to be released
manually when required.
• Ensure that the surfaces on which the various devices are to be installed are
strong and capable of ensuring a firm hold.
• Ensure that each device is installed in a position which is protected and does
not expose it to accidental impacts.
• Ensure that all the electrical cables to be used are the type listed in Table 1.

3.2 - Application limits

Before starting gearmotor installation, perform the following checks:
• ensure that the leaf to be motor-powered remains within the limits specified in
Graph 1;
• maximum leaf width: 2,4 m (with weight up to max. 160 kg);
• maximum leaf weight: 250 kg (with width up to max. 1,5 m);
• check limits specified in the table of "Product technical specifications";
• minimum width of space for gearmotor installation: 170 mm;
• The arm fixing bracket must be located in a resistant area of the leaf (for exam-
ple the frame), to guarantee a solid and safe fixture.

C: BLUEBUS DEVICE cable
D: KEY-OPERATED SELECTOR SWITCH cable
E: GEARMOTOR POWER SUPPLY Cable
F: FLASHING LIGHT with aerial cable
Note 1 – If the power cable exceeds a length of 30 m, use a cable with a larger section (3x2.5 mm
Note 2 – If the Bluebus cable exceeds a length of 20 m, up to a maximum of 40 m, use a cable with a larger section (2 x 1 mm
Note 3 – These 2 cables may be replaced with a single cable of 4 x 0,5 mm
CAUTION! – The cables used must be suited to the type of environment of the installation site.

3.3 - Preliminary installation set-up work

Fig. 3 provides an example of an automation system, produced using Nice com-
ponents (some components may not be present in the kit):
a - Gearmotor with control unit model HO7124
b - Gearmotor without control unit model HO7224
c - Flashing light MLBT
d - Pair of photocells model MOFB
e - Digital keypad (mod. MOTB) - Transponder badge reader (mod. MOMB) –
Key-operated selector switch (mod. MOSE)
f - Pair of posts for photocells
g - Mechanical stop on closing
h - Electric lock
These parts are positioned according to a typical standard layout. With refer-
ence to fig. 3, locate the approximate position for installation of each component
envisaged in the system. Important – Before installation, prepare the electric
cables required for the system, with reference to fig. 4 and "Table 1 - Techni-
cal specifications of electric cables".
Caution – When laying the ducting for routing the electrical cables, also take
into account that due to possible deposits of water in the routing ducts, the con-
nection pipelines must not create condensate in the control unit, with conse-
quent damage to the electronic circuits.

3.4 - Installation of gearmotor mod. HO7124 - HO7224

• Incorrect installation may cause serious physical injury to those working
on or using the system.
• Before starting automation assembly, make the preliminary checks as
described in paragraphs 3.1 and 3.2.
01. Measure position "B" (fig. 5);
02. Move the leaf to the maximum required opening position and check that
the angle found remains within the values shown on Graph 2;
03. On Graph 2, with value "B" and the opening angle, calculate value "A" (fig.
6). Example: if "B" is 100 mm and the required angle is 100°, value "A" is
approx. 180 mm.

04. Mount the gearrmotor fixing bracket on the wall in a horizontal position, as
shown in fig. 7: use suitable plugs, screws and washers (not supplied);
05. Fix the gearmotor to the previously mounted bracket, as shown in fig. 7-3:
use the screw supplied (M4.8x13);
06. Then fix the curved arm to the straight arm, using the pin and Benzing
snap ring (fig. 7-4); fix the leaf fixing bracket to the curved arm, using the
pin and Benzing snap ring (fig. 7-4);
07. Manually release the gearmotor (fig. 7-6), see paragraph 3.6;
08. At this point, determine the zone for fixing the bracket ion the gate leaf, setting
2.4
the gearmotor arms to the maximum extension (fig. 7-7): it is important to
position the bracket at the point furthest from the position of the gearmotor;
