CORRECT OPERATION OF THE SYSTEM REQUIRES THAT THE INDICATED
DIMENSIONS ARE OBSERVED.
If it is not possible to maintain the dimensions indicated in the table, different measurements should be
calculated with reference to the following items:
• For b
= 90° ®
A + B = Cu
• For b
> 90° ®
A + B < Cu (b
• Dimension A must always be greater than the sum of dimensions D+d1.
• In the event of very thick gates, with consequent difficulties in maintaining dimension D, it is possible to
increase dimension D; it is also advisable to increase dimension A by the same amount, in any case
observing the rules indicated above.
• The difference between A and B must not exceed 50 mm; greater differences cause a non-constant door
movement (drive/thrust force and movement speed vary during operation).
