Nice AVIO500 Instructions Et Avertissements Pour L'installation Et L'utilisation page 32

STEP 3
The installation of AVIO500 must be carried out by
qualified personnel in compliance with current legislation,
standards and regulations, and the directions provided in
this manual.
3.1 – PRELIMINARY CHECKS
Before proceeding with the installation of AVIO500 you must:
• Verify and ensure after installation that no door parts obstruct
public roadways or pavements.
• Check that all the materials are in excellent condition, suitable
for use and that they conform to the standards currently in force.
• Make sure that the structure of the gate is suitable for automa-
tion.
• Make sure that the force and dimensions of the door fall within
the specified operating limits provided in chapter 2.2 ("Operating
limits").
• Check that the static friction (that is, the force required to start
the movement of the door) is less than half the "maximum torque",
and that the dynamic friction (that is, the force required to keep the
door in movement) is less than half the "nominal torque". Com-
pare the resulting values with those specified in step 15 ("Techni-
cal specifications"). The manufacturer recommends a 50% mar-
gin on the force, as unfavourable climatic conditions may cause
an increase in the friction.
• Make sure that there are no points of greater friction in the

3.2 – FITTING AVIO500
Installation of the AVIO500 gearmotor comprises 3 stages:
• Assembly guides (see sections 3.2.1 and 3.2.2).
• Mounting the gearmotor to the guide (see section 3.2.3)
3.2.1 – Assemblyof guide supplied to AVIO500 for not
assembled version only)
The guide that is supplied must be assembled as follows:
01. Referring to fig. 4, remove the belt tensioner device (4a); in-
sert one end of the belt into the pulley (4b); reintroduce the belt
tensioner device into the guide (4c).
02. Pass the same end of the belt through the head [A], as in fig.
5. NB - Make sure that the belt is correctly positioned: it must be
with the teeth facing inwards, straight and without twists.
03. Turn the lower section of the carriage so that the grooves cor-
respond with the two ends of the belt, as in fig. 6.
04. Place both ends of the belt into all the shaped slots of the
lower carriage [B]. Secure the ends of the belt with the 2 screws
(V4.2x9.5) and 2 brackets, as in fig. 7.
05. Fix the belt guide [C] to the upper carriage [D] with the V6x18
screw and related M6 nut, as in fig. 8.

opening or closing travel of the door.
• Make sure that the mechanical stops are sturdy enough, and
that there is no danger of the door derailing.
• Make sure that the door is well balanced: it must not move by
itself when left stationary in any position.
• Make sure that the mounting positions of the various devices
(photocells, keys, etc.) are protected from impact and that the
mounting surfaces are sufficiently sturdy.
• Make sure that the minimum and maximum clearances speci-
fied in fig. 2 and 3 are observed.
• Check and ensure that the manual release is fitted at a maxi-
mum height of 1.8 m.
• Components must never be immersed in water or other liquids.
• Keep all AVIO500 components away from heat sources and
open flames; these could damage the components and cause
malfunctions, fire or dangerous situations.
• If the door includes an access door, make sure that it does not
obstruct normal travel. Fit a suitable interlock system if necessary.
• Only insert the AVIO500 plug into sockets equipped with a safe-
ty grounding system.
• The socket must be protected by suitable magneto-thermal
and differential switches.

06. Insert the upper carriage [D] into the lower carriage [B] and
place the entire carriage assembly inside the guide, as in fig. 9.
07. Hammer the three pieces of the guide into place inside the
connection brackets [E], as in fig. 10 and 11. Important – the
guides must slide into the brackets until they click into position.
08. Carefully position the belt into the guide, making sure that it
is not twisted.
09. Push the head [A] into the free end of the guide using signifi-
cant force, as in fig. 12.
10. Finally, tension the belt with the adjustment screw [F] of the
belt tensioner device, as in fig. 13.
CAUTION! the gearmotor could break if the belt is TOO
taut, and it could cause unpleasant noise if it is TOO slack.
