SYSTEM LAY-OUT
2.0 SYSTEM ELECTRICAL CONNECTION
- When making the electrical connections,carefully follow the instructions for each of
the components, referring to the wiring diagram B1 .
Warning
!
• Make the electrical connection of the single components after having completed
their installation.
• The entire circuit must be made consistent with the current safety regulations.
• Use cables with a cross-section of 1.5 mm2 for the wiring.
• Protect the operator power cable with a sheath if necessary; do this before connecting
the cable to the junction boxes.
Warning
!
• Every operator comes complete with a pickup capacitor. During installation, connect
the capacitor to the electrical equipment according to the wiring diagram supplied.
- After making the electrical connections, check the thrust force at the end of the gate
leaf; if necessary, adjust the pressure of the operator according to the procedure
described in the specific paragraph.

3. INSTALLING THE OPERATOR
3.0 POSITIONING THE MOUNTINGS
The following table ( C1 ) indicates the recommended data for defining the position of the
operator mountings in relation to the centre of rotation of the gate leaf.
The distances
A and B will give:
• The useful stroke length ( C ) of the piston
• The peripheral velocity of the gate leaf
• The angle of maximum opening of the gate leaf
• The holding capacity of the lock in relation to distance
E (which must always be less
than B when the operator is fitted with a hydraulic lock); the distance E is obtained, in
practice, by measuring the distance between front mounting fulcrum and gate hinge
axis (see fig.
C1 ).
Caution
• The sum A+B corresponds to the useful stroke length of the piston (C) for a 90°
opening of the gate leaf.
• The minimum value of distances A and B is 70 mm; the maximum one is indicated in
column B of the table (see fig. C1).
• Distances A and B must be as equal as possible in order to have a uniform peripheral
velocity.
• If the gate leaf shall be opened by more than 90°, first of all find the best A and B
measurements for mounting, then reduce distance B to the desired opening angle,
making sure, by checking the distance Y, that the corner of the post does not interfere
with the operator action.
Warning
!
• The greater the distance B in relation to E, the more efficient the holding capacity
of the hydraulic lock (for all types of operator).
• If the gate leaf is closed with an electric lock, then E must always be less than or
equal to B (never greater).
