INSTALLING THE AUTOMATED SYSTEM
3.2.
INSTALLATION DIMENSIONS
3.1.
PRELIMINARY CHECKS
To ensure a correctly operating automated system, the structure
of the existing gate or gate to be built must satisfy the following
requirements:
•
Max length of leaves according to the dimensions of Table 1.
•
A strong and rigid leaf structure.
•
Smooth, uniform leaves movement, without any irregular friction
during the entire travel;
•
Existing hinges in good condition.
•
Travel limit mechanical stops must be provided.
We advise you to carry out the metalwork jobs before installing
the automated system.
The condition of the structure directly influences the reliability and
safety of the automated system.
Table A
: Recommended dimensions for standard operators
Table B
: Recommended dimensions for long operators
(*) Rod effective stroke (**) maximum dimension
c
= The effective rod stroke is shorter than the maximum stroke,
in order to prevent the rod from reaching its stop point
internally, during the opening and closing stages.
(*) Rod effective stroke (**) maximum dimension
3.3.
INSTALLATION OF THE OPERATORS
1)
Fasten the rear attachment on the pilaster, following the
indications in
Tables A/B
. Modify, if necessary, the length of
the supplied attachment.
Attention
: To avoid compromising good operator
functionality, we recommend you to respect the indicated
dimensions.
• For iron pilasters, accurately weld the rear attachment
(ref.
, Fig. 6) directly on the pilaster.
• For masonry pilasters, select one of the following solutions:
A) appropriately lay a walling-in plate and then
accurately weld the rear attachment.
B) secure, with screws and expansion plugs, the rear
attachment plate (ref. a, Fig.6) to the pilaster and
then accurately weld the rear attachment to the
plate as shown in Fig. 6.
3.2.1.
GENERAL RULES FOR DETERMINING THE
INSTALLATION DIMENSIONS
If the dimensions indicated in table A or B cannot be executed,
the following must be considered in order to determine different
measurements:
-
to obtain
90° opening of the leaf: a + b = c.
-
to obtain
over 90° opening of the leaf: a + b < c.
-
lower a and b dimensions will result in higher speeds
. We advise
you to observe the current legal regulations;
-
limit the difference of the a and b dimensions to within 40 mm
:
higher differences will considerably vary speed during the
opening and closing motion;
-
for reasons of operator dimensions, the
minimum Z dimension
is 50 mm
(Fig. 4);
-
if the pilaster dimensions or the position of the hinge (dimension
d
) do not make it possible to contain dimension
a
to the
required size, a niche must be made in the pilaster as shown
in Fig. 5;
-
dimension
a
must always be larger than dimension
E
.
For installations opening toward the outside, refer to paragraph
9.1.
