3. Insert the bushing (4) into the chosen hole on the rear bracket (1) and thread the operator fork (5) on to the bracket, aligning the hole with the
bushing. Fix the whole set with a screw, washer and self-locking nut and tighten.
4. Fix the operator to the front bracket (2) using a screw and washer, and tighten.
5. Manually open and close the gate several times and check that the movement of the leaf is regular and that the operator moves on a plane parallel
to the gate’s plane of movement.
6. Check that the nut screw bushing support (3) slides perfectly on the operator nut screw and that, with the leaf closed and open, there are at least
5 mm between the nut screw bushing support (3) and the closure (6) and opening (7) stop plates.
7. If necessary, use a different hole on the rear bracket and repeat the operations indicated in points 3 and 4. .
8. Dene with precision the opening and closure positions of the stop plates on the operator’s internal slider, as follows:
• take the gate to a closed position, abutting against the stop plate.
• loosen the support of the closure stop plate (6) using a suitable wrench and position so that it touches the nut screw bushing support (3); then
lock again by tightening.
• Take the gate leaf to the desired opening position;
• loosen the support of the opening stop plate (7) using a suitable wrench and position so that it touches the nut screw bushing support (3); then
lock again by tightening.
9. Denitively x the front bracket (2) of the operator, to the leaf of the gate, choosing the clamping means to suit the material of the leaf (with screws
or by welding).
10. Release the operator as indicated in the RELEASING THE OPERATOR chapter.
2.5 Releasing the operator
ATTENTION:
• The tter must permanently x the label describing the manual release operation close to the manual release key.
• The activation of the manual release could cause an uncontrolled movement of the gate in the event of mechanical damage or
mechanical unbalance conditions.
• Before performing the manoeuvre, switch off the electricity supply to the automation.
• To avoid breaking the key, do not apply excessive force.
This command makes it possible to release the operator transmission and to perform leaf movement manually. It can be used in the case of a blackout or
system malfunction.
The release is activated using a wrench, which must be kept in a safe place.
a) Lift the lock protection cover (1).
b) Insert the key (2) into the lock and turn clockwise through 360°.
c) The leaf is now free and can be moved manually.
d) To relock the leaf, insert the key (2) and turn anticlockwise through 360°.
