- For reasons of operator clearance, the minimum value for
Z is
50 mm
(Fig. A)
If the dimensions of the gate post or position of the hinge do
not allow for the specified distance of “
a
”, make a recess in the
gate post as shown in Fig. B.
- Dimension

INSTALLATION OF THE AUTOMATION SYSTEM
3.1.
PRELIMINARY CHECKS
To ensure trouble-free operation, make sure that the gate
(whether existing or yet to be installed) has the following
specifications:
•max. length of each gate leaf: 7 metres
•strong and rigid leaf frame
•smooth gate movement, with no stiff points
•hinges in good condition
•phisical travel limit stops
If any welding or brazing has to be done on the gate, do this
before installing the automation system. The good order of the
structure directly influences the reliability and safety of the
automation system.
3.2.
INSTALLATION OF THE OPERATORS
1) Fix the rear bracket to the gate post according to the
instructions in
Table 2
. Adjust the length of the bracket if
necessary.
Warning
: Observe the specified dimensions to ensure correct
operator functioning.
In the case of iron gate posts, weld the bracket directly onto
the gate post.
In the case of brick/concrete gate posts, flush-mount a wall
plate (2, Fig. 4), and weld the bracket to the plate (Fig. 4).
2) Fix the operator to the rear bracket by means of the screws
supplied (Fig. 4).
3) Screw the front bracket half-way onto the rod (1, Fig. 6) and
secure with the nut provided.
4) Release the operator (see paragraph 5).
5) Extend the rod to the end of its stroke and then retract it by
Table 2
INSTALLATION DIMENSIONS
about 5 mm (Fig. 5).
6) Lock the operator (see paragraph 6)
7) Fit the front bracket onto the rod as shown in Fig. 6, ref. 2.
8) Close the gate leaf and, keeping the operator perfectly
horizontal, locate the leaf attachment position of the front
bracket (Fig. 7).
9) Fix the front bracket temporarily to the leaf by two welds.
N.B.:
If the gate frame does not allow for secure fixing of the
bracket, add a support plate.
10) Release the operator and ensure that the gate opens smoothly

CALCULATING INSTALLATION DIMENSIONS: GENERAL
RULES
If modifications to the dimensions specified in Table A or B are
necessary, proceed as follows:
- For
90° leaf opening: a + b = c
- For
leaf opening over 90°:
a + b < c
-
The smaller the dimensions of a and b the higher the gate speed
.
Always respect current standards.
-
Limit the difference between a and b to within 40 mm
: larger
differences alter speed considerably during opening and
closing.
