MOUNTINGS PLACEMENT
Choose the most suitable height on the wing to position the
front operator mounting. Where possible, place it half way up
the wing. The best mounting place is usually the strongest
point where there is little fl exing. Note: Do not install near
the ground. Install where the manual emergency release can
be used easily.
Check if the mounting position you have chosen requires
further reinforcement of strengthening. If there is no profi le
strip on the structure, you should weld a support in the position
where the front mounting will be attached. The strip should be
large enough to distribute the load evenly (Fig.3).
Decide the lay-out of the operator mountings; measure from
the wings centre of rotation (Fig.8 and Table 3).
CAUTION! The measurements A and B as used as references
to defi ne:
- the effective stroke (C) of the operator
- the peripheral speed of the wing
-the maximum opening angle of the wing (
Fig. 8
Use measurements A and B to position the rear mounting.
The measurements A and B should be as similar to each
other as possible in order to ensure uniform peripheral
speeds.
The minimum value for A is 70 mm.
The minimum value for B is 90 mm.
L : length of the mounting (see par. 3.5).
Y: distance from the pillar edge to the axis
of the gate hinge
E: distance from the front
mounting pivot to the axis
of the gate hinge.
IMPORTANT!
In order to ensure a fi rm lock during closing the measurement
B should always be higher than the measurement E.
B > E
!
Warning
Always CHECK that the installation measurements
and angles match those specifi ed for the gate, pillar
and hinge types you are using.
The recommended data listed in Table 3 is not
mandatory. This data is provided as a guide only and is
calculated for an E value of 70 mm.

IMPORTANT. If the distance between the pillar edge and the centre of rotation is higher than the maximum
Y value shown on the table, or if the wing is anchored to a continuous wall, you should create a niche to
support the operator (see par. 4.6).

NOTE: The sum of A + B equals the effective stroke (C) need to
obtain a wing opening of 90°.
If you wish to open the gate to an angle greater than 90°, decide
the best positions for the A and B measurements and then reduce
the measurement B until you get to the required opening angle.

Care should be taken to decide the Y measurement; an incorrect
(mm)
measurement at this point will cause interference between the

operator and the pillar edge.
