If the size of the pilaster or the position of the hinge should not permit
installation of the operator, a
niche will have to be made in the
pilaster in order not to change
value A, as indicated in figure 6.
The size of the niche must be such
as to permit easy installation of the
operator, not limiting its rotation
and allowing activation of the
release device.
The rear bracket, adjustable to different positions, facilitates the
installation procedure, being adaptable to different types of gate
and limiting any modifications necessary to satisfy installation
values A and B. Figure 7 shows certain positions which the bracket
can take; all positions intermediate to those shown may be
obtained.
Positions must be chosen which permit assembly of the bracket,
using both the securing screws.
3.3.1. g
eNeral rules for determiNatioN of the iNstallatioN values
• To obtain opening of the leaf to 90° : A+B=C.
• To obtain opening of the leaf more than 90° : A+B<C
• Lower values of A and B produce higher peripheral leaf
speeds.
• Limit the difference between value A and value B to within 4 cm,
greater differences cause variations in speed during movement
of the gate on opening and closing.
• Keep the value Z so that the operator does not strike against
the pilaster.
• The mechanical stops intervene in the first and final 50 mm of the
stroke. Not exploiting the entire operator stroke could limit the
field of regulation or reduce it to zero.
3.4. INSTALLATION OF THE OPERATORS
To correctly install the operators, follow the procedure indicated:
1. Secure the fixed part of the rear bracket in the position
determined previously, using suitable assembly systems. In the
case of iron pillars, the bracket may be welded directly to the
pilaster, see figures 8 and 9.
During assembly procedures, check that the bracket is
perfectly horizontal using a spirit level.

2. Secure the rear bracket, as indicated in figure 10, so as to
s a t i s f y v a l u e s A a n d B
determined previously.

3. Secure the rear fitting of the operator as indicated in figure
11.
4. Check that the front fitting is in the position indicated in figure
12 (with the mechanical stop at closing) or in figure 13 (with
no mechanical stop at closing). If this should not occur, the
operator must be temporarily powered, in order to bring the
fitting into position.
To do this, a 12 V DC battery may be used.

5. Secure the front bracket as indicated in figure 14.
