5. INSTALLATION OF THE AUTOMATED SYSTEM
5.1.
PRELIMINARY CHECKS
To ensure trouble-free operation of the automated system,
make sure that the structure of the existing gate or the gate
to be installed, complies with the following requirements:
•
max. single leaf length up to 2 metres (with V and VR
operator versions);
•
max. single leaf length up to 3.5 metres (with L and LR
operator versions);
•
sturdy and rigid leaf structure;
•
proper and uniform movement of the leaves, without
any irregular friction during their entire travel;
•
good condition of existing hinges;
•
presence of mechanical stops.
•
presence of the electric lock for the reversing version.
•
presence of an efficient earthing for the electric
connection of the operator.
We advise you to carry out any metalwork jobs before
installing the automated system.
The condition of the structure directly affects the reliability
and safety of the automated system.
5.2.
INSTALLATION OF THE OPERATORS
1) Secure the rear bracket on the pillar according to the
instructions of
Dwg. A
. If necessary, change the length
of the supplied bracket. Any securing errors may be
remedied thanks to 4 securing holes on the rear bracket.
Attention
: observe the indicated dimensions in order not
to endanger the operator efficiency.
In case of iron pillar, carefully weld the bracket directly
on the pillar (Fig. 4).
In case of masonry pillar, use the optional plate for a
securing to wall or to be bolted (Fig. 4).
Then carefully weld the bracket on the plate.

GENERAL RULES TO DETERMINE
THE INSTALLATION DIMENSIONS
If the dimensions indicated in table A cannot be realized,
the following must be taken into consideration in order to
determine different measures:
-
to get
90° leaf opening: a + b = c
-
to get
leaf opening over 90°: a + b < c
-
lower a and b dimensions determine higher speed
.
Current standards have to be complied with.
-
limit the difference of the dimensions a and b within
4 cm
: higher differences cause high speed variations
during the opening and closing movement.
-
due to the operator overall dimensions, the
min. Z
dimension is 80 mm
(Fig. A).
-
with the
LS
versions, dimensions
A
and
B
must be
used as they enable use of the entire travel. Shorter
travel distances could limit or reduce the limit-
switch adjustment range to zero.
-
If the pillar dimensions or the hinge position make it
impossible to keep the dimensions
a
within the
desired measure, a niche on the pillar is to be
executed as shown in Fig. B.
-
in the LS versions, the limit-switches are tripped only
during the first and last 25 mm of travel. As a result,
the full travel distance C must be used.
