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 dimen-
sions (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.
• 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 installing the gearmotor, ensure that the specifications meet the
requirements in terms of application limits as stated below and within the limits
as specified in "Product Technical Specifications".
With the LONG motor arm :
- maximum leaf width: 3.50 m (= maximum leaf weight: 200 kg)
With the SHORT motor arm :
- maximum leaf width: 3.00 m (= maximum leaf weight: 180 kg)
• Checks to perform: note on Graph 1 alongside, the weight and width of the
leaf; trace two lines from this point and check that these intersect within one of
the two grey areas of the graph. Caution! - If the lines intersect in the white
area, this product cannot be used to automate the gate.
• To enable installation of the gearmotor, the minimum column width must be
210 mm.
• The arm fixing bracket must be located in a resistant area of the leaf (for
example the frame), to guarantee a solid and safe fixture;
• Check position "E" (fig. 2):
- If position "E" is between 300 mm (minimum) and 650 mm (maximum),
the gearmotor arm must be set at the SHORT length. In these conditions,
the maximum leaf opening can reach 90°.
- If position "E" is equal to or over 650 mm, the gearmotor arm must be
set at the LONG length. In these conditions, the maximum leaf opening can
reach 110°.
Connection
A: Cable CONTROL UNIT POWER SUPPLY
B: ELECTRIC LOCK Cable
C: BLUEBUS DEVICE cable
D: KEY-OPERATED SELECTOR SWITCH cable
E: GEARMOTOR POWER SUPPLY Cable
ENCODER CONNECTION 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 mm2); in this case earthing is required in the vicinity of the automation.
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
Note 4 – These cables may be replaced with a single cable of 5 x 1,5 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
components (some components may not be present in the kit):
a - Gearmotor with control unit model HK7024
b - Gearmotor without control unit model HK7224
c - Flashing light
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 compo-
nent envisaged in the system. Important – Before installation, prepare the elec-
tric cables required for the system, with reference to fig. 4 and "Table 1 - Tech-
nical 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
connection pipelines must not create condensate in the control unit, with con-
sequent damage to the electronic circuits.
3.4 - Installation of gearmotor mod. HK7024 - HK7224
WARNINGS
• 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.
Before starting installation, determine the length of the gearmotor arm with ref-
erence to paragraph 3.4.1.
3.4.1 - Determining the length of the gearmotor arm
01. Assemble the components of the motor arm as shown in fig. 5.
02. Establish the position of the gearmotor in the VERTICAL direction:
on the column, trace a horizontal line at the same height as the designated
position of the fixing bracket for the arm on the leaf after installation (fig. 6).
03. Establish the position of the gearmotor in the HORIZONTAL direction
(position A):
CAUTION! – If there is a fixed obstacle (wall, tree, etc.) in the vicinity of
the installation area, measure value E (fig. 2) and proceed as follows:
• if value E is equal to or greater than 650 mm, refer to paragraph 3.4.2
Maximum admissible length
