Installation
The installation of OVO 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 OVO you must:
•
Verify and ensure after installation that no door parts obstruct pub-
lic 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 automation.
•
Make sure that the force and dimensions of the door fall within the
specified operating limits provided in chapter 2.1 ("Operating limits”).
•
Check that the static friction (that is, the force required to start the
movement of the leaf) is less than half the "maximum torque", and
that the dynamic friction (that is, the force required to keep the leaf
in movement) is less than half the "nominal torque". Compare the re-
sulting values with those specified in section 9 ("Technical specifica
-
tions"). The manufacturer recommends a 50% margin 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 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 (pho-
tocells, keys, etc.) are protected from impact and that the mounting
surfaces are sufficiently sturdy.
• Make sure that the minimum and maximum clearances specified in
fig. 2
and
3
are observed.

• Check and ensure that the manual release is fitted at a maximum
height of 1.8 m.
•
Components must never be immersed in water or other liquids.
•
Keep all OVO components away from heat sources and open
flames; these could damage the components and cause malfunc
-
tions, 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 OVO plug into sockets equipped with a safety
grounding system.
•
The socket must be protected by suitable magneto-thermal and
differential switches.

Fitting OVO
Installation of the OVO gearmotor comprises 3 stages:
•
Assembly of GRO33 and GRO13 guides (see sections 3.2.1 and
3.2.2).
•
Mounting the gearmotor to the guide (see section 3.2.3)
3.2.1 - Assembly of guide supplied GRO33
The guide that is supplied with GRO33 must be assembled as fol-
lows:
01.
Referring to
fig. 4
, remove the belt tensioner device (
4a
); insert
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 washers (R05), 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
.
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 con-
nection 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 significant
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.
3.2.2 - Assembly of guide supplied GRO13
The GRO13 guide is already assembled. All you have to do is ten-
sioning the belt using the M8 nut [F] (
fig. 13
) until it is sufficiently taut.
