Nice HK7024 Instructions And Warnings For Installation And Use page 15

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
• if value E is between 300 mm (minimum) and 650 mm (maximum),
refer to paragraph 3.4.3
3.4.2 - Installing the gearmotor with the LONG MOTOR ARM LENGTH
01. a) On the column, measure value B (fig. 7) = distance between the leaf
rotation fulcrum and the column surface designated for fixture of the rear
gearmotor bracket.
b) Move the leaf to the required opening position (maximum 110°): value of
angle.
c) On Graph 2 note the obtained value B and from this point, trace a hori-
zontal line until it intersects the area covering the angle value measured in
point b.
d) At the points of intersection between the horizontal line and the area,
trace vertical lines to determine the feasible values for value A (fig. 8).
Then choose a value for A within this range.
e) On the column, mark the value found for value A and trace a vertical line
at this point.
02. Fixing the bracket on the column (fig. 9):
f) phases 1-2: Place the bracket on the column, aligning its vertical cen-
treline with the previously traced vertical line (value A), and its arm with
horizontal line traced during procedure 3.4.1. In this phase, ensure that
the gearmotor is perfectly level: an offset gearmotor can cause automation
malfunctions.
g) phases 3-4: Mark the fixing points, drill the holes in the column and
insert the plugs, and then secure the bracket using suitable screws and
washers.
03. Fixing the gearmotor arm on the leaf:
h) Move the gate leaf to the maximum closing position;
i) phase 5: Fix the gearmotor to the bracket with the two screws and nuts
supplied;
l) Release the gearmotor; see chap. 3.6;
m) phase 6: Firmly push the gearmotor arm to its maximum extension.
Caution! - Ensure that the arm stops and locks in place at its travel limit;
n) Move the arm towards the leaf, and position the fixing bracket on the leaf.
o) phase 7: Ensure that the gearmotor arm is perfectly level and use a
pencil to mark the centre of the profile of the slots on the bracket, to
enable future fine adjustment of leaf closure (see paragraph 4.8).
p) Use one hand to keep the bracket in contact with the leaf and perform a
complete opening and closing cycle.
q) phase 8: Drill the leaf at the marked points, remove the bracket from the
arm and fix it on the gate leaf with suitable screws.
r) phase 9: Fix the arm to the bracket, inserting the pin and Benzing snap
ring. Important – Check that the bracket and arm are perfectly level. If
necessary, loosen the screws and level correctly.
s) Position the mechanical limit stops with reference to chap. 3.5;
t) phase 10: Lastly, manually move the gate leaf to approx. mid-travel and
block the gearmotor with the relative key (see chap. 3.6). Then manually
move the gate leaf by a few centimetres in the opening direction.
04. If the gate to be automated is a two-leaf model, repeat the same opera-
tions as described in this chapter 3.4 to install the second gearmotor.
3.4.3 - Installing the gearmotor with the SHORT MOTOR ARM LENGTH

01. a) On the column, measure value B (fig. 7) = distance between the leaf
rotation fulcrum and the column surface designated for fixture of the rear
gearmotor bracket.
b) On Graph 2 note the obtained value B and from this point, trace a
horizontal line until it intersects the area covering the range 90° - 95°.
c) At the points of intersection between the horizontal line and the area,
trace vertical lines to determine the feasible values for value A (graph 2).
Then choose a value for A within this range.
d) On the column, mark the value found for value A and trace a vertical line
at this point.
02. Fixing the bracket on the column (fig. 10):
e) phases 1-2: Place the bracket on the column, aligning its vertical cen-
treline with the previously traced vertical line (value A), and its arm with
horizontal line traced during procedure 3.4.1. In this phase, ensure that
the gearmotor is perfectly level: an offset gearmotor can cause automation
malfunctions.
f) phases 3-4: Mark the fixing points, drill the holes in the column and
insert the plugs, and then secure the bracket using suitable screws and
washers.
g) Move the gate leaf to the maximum closing position;
h) phase 5: Fix the gearmotor to the bracket with the two screws and nuts
supplied;
i) Release the gearmotor; see chap. 3.6;
03. Check the length of the slotted arm with respect to the configura-
tion:
l) phase 6: Move the arm towards the leaf, and position the fixing bracket
on the leaf. Caution! - manually push the curved arm against the leaf
until the arm is locked in place (maximum opening).
m) phase 7: Ensure that the gearmotor arm is perfectly level and use a
pencil to mark the centre of the profile of the slots on the bracket, to
enable future fine adjustment of leaf closure (see paragraph 4.8).
n) Provisionally secure the bracket on the leaf and move the latter to the
maximum opening position.
04. Fixing the gearmotor arm on the leaf:
o) phase 8: Drill the leaf at the previously marked points.
p) phases 9-10: Remove the bracket from the arm and fix it on the gate
leaf with suitable screws.
q) phase 11: Fix the arm to the bracket, inserting the pin and Benzing
snap ring. Important - Check that the bracket and arm are perfectly level.
If necessary, loosen the screws and level correctly.
r) Position the mechanical limit stops with reference to chap. 3.5;
s) phase 12: Lastly, manually move the gate leaf to approx. mid-travel and
block the gearmotor with the relative key (see chap. 3.6).Then manually
move the gate leaf by a few centimetres in the opening direction.
05. If the gate to be automated is a two-leaf model, repeat the same opera-
tions as described in this chapter 3.4 to install the second gearmotor.
3.5 - Mechanical limiter adjustment
01. Manually move the gate leafs to the maximum opening position;
02. Rotate the plastic disk on the lower section of the gearmotor, to position
the aperture under the arm as shown in fig. 11-1;
03. Insert the limiter in the first possible place: try to insert as shown in fig.
11-2 (opening direction);
04. Rotate the disk to prevent the limiter from dropping, moving the aperture
to the position shown in fig. 11-3; for more precise adjustments, use the
adjustment screw (fig. 11-4);
