2.3) Assembly
To assemble the system correctly, check the following points:
1) Projection of column C
2) Opening angle
α
3) Speed
4) Thrust
2.3.1) Fixing the rear bracket
Carry out the following operations:
1.1Measure the value of C (e.g.: 70mm).
1.2Find the value of C in the graph and draw a horizontal line (fig.8).
1.3Find the minimum value of “B” on the graph using the straight line
you have just drawn (the example shows 130 mm fig.9), the area
above the line contains the points where the bracket can be
fixed.
2 There is a relationship between the opening angle of the gate and
the positions of the bracket (A and B) as can be seen in the graph
relative to the product (paragraph on fixing the rear bracket)
where the different coloured areas represent the maximum
permitted angles. If, for example (fig.9), the gate must be
opened by 100°÷110°, A and B must identify a point on the
graph belonging to the corresponding colour area.
3 Inside this area, remember that the thrust applied to the gate and
the opening and closing time are directly proportional to the
values of A and B and that these values must be similar for linear
operation; the recommended installation line should therefore be
respected.
