5.3) Electrical installation set-up
Lay out the electrical installation as shown in fig. 2, with reference to the CEI
64-8 and IEC 364 provisions, complying with the HD 384 and other national
standards in force for electrical installation. The mains power supply connec-
tions must be kept totally separate from the service connections (photocells,
electric edges, control devices etc.).
WARNING! For connection to the mains, use a multipolar cable with a
minimum of 3x1.5mm

cross section and complying with the previou-

sly mentioned regulations. For example, if the cable is out side (in the
open), it has to be at least equal to H07RN-F, but if it is on the inside
(or outside but placed in a plastic cable cannel) it has to be or at least
egual to H05VV-F with section 3x1.5mm

Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards. Fig. 2 shows the number of con-
nections and the cross section for cables having a length of approximately
100 metres; in case of longer cables, calculate the cross section for the
actual automation load.
Warning! For actuator wiring and accessory connection, refer to the relevant
instruction manuals. The control panels and accessories must be suitable
for use and conform to current standards.

5.4) Foundation case cementing
The foundation case must be cemented under the hinge pivot, taking into
consideration that the actuator bearing shaft must be perfectly aligned with
the leaf rotation axis. If the gate has fixed hinges, remove the gate and the
lower hinge. If the leaf is sufficiently separated from the ground and cannot
be removed, proceed to supporting it by means of a shim placed between
the ground and the leaf during installation. If the gate has adjustable hinges,
remove the lower one, slacken the upper hinge and move the leaf to the
side. If the gate has been recently installed, fit an upper adjustable hinge.
Dig a foundation hole having the dimensions specified in fig.4. Lay an drain
pipe (fig. 4) for rainwater in order to prevent it from being collected inside the
foundation case. Lay a raceway for the power supply cable as far as con-
nector block “D”. Lay a solid foundation (fig.3) at the bottom, where to bury
the foundation box. To obtain good squareness between cases and leaves,
set out their alignment using a stretched rope between the 2 bearing pivots,
and aligning the 2 reference points “C” with each other (see fig.12).
Let the cement harden for the time needed.

6) GATE LEAF FITTING
• Abundantly grease the pivot in the foundation case.
• Position the lever assembly by inserting pipe “A” into the pivot of the

foundation case, as in fig.9. If the height of the assembled levers is not
sufficient, insert shim “S” between the assembled lever unit and the gate
leaf, as in fig.5.

• Place the gate leaves in the closing and in the closed position against the

centre stop plate.

• Perfectly align the assembled lever unit to the hinge.
• If a shim is used, weld it to the leaf first and then weld the lever unit

to the shim.

• Check the leaf operation.
• If the gearmotor is not to be installed, fit the foundation case cover and

fix with suitable screws.

At this stage, the gate opens and closes manually. All that remains to be

done is to position the gearmotor.

7) GEARMOTOR FITTING
Remove the nuts from the bottom of the case using a CH19 socket wrench.
The gearmotor is to be fixed to the foundation case in the position shown in
fig.6 and 8, using the 4 nuts which were previously removed.
• Tighten screws ”VR” (fig.7) and respective locknuts to the end-of-stroke

brackets and identify the left or right fastening position (fig.8).

• Fix the mechanical end-of-stroke brackets using the M8 screws pro-

vided (fig.7).

• Fit the motor-pivot connecting lever components following the correct

sequence given in fig.9.

In the case where the position of the levers interferes with the assembly of

the components, supply the motors with current (by means of the control
unit) until the levers reach the required position.

•

Fig.9: insert the greaser (C) into the threaded hole of the lever (A). The
type of grease recommended is: R

•  Grease the hub where pipe “A” must be inserted.
•  Check the opening and closing operations.
•  Attach to the leaf the internal and external release labels observing the

direction and position indicated in fig.14. The open-padlock symbol must
always be directed towards the leaf rotation axis.

• Connection of the gearmotor cable must be carried out in a junction box

positioned outside the foundation case without cutting the cable supplied
as standard (Fig.2-4-5 Ref.D).

8) END-OF-STROKE ADJUSTMENT
If no ground stop plates “FA” are fitted, adjust the internal stops using the
screws “VRC-VRO” (fig.10-11) until the leaf stops at the required point.
The mechanical stop for the opening and closing operations can be adjusted
by means of the appropriate screws “VRC-VRO”.
• On

CLOSING (fig.10): The end-of-stroke adjusting screw “VRC” should

come into contact with lever “L” after the leaf has reached the centre stop
plate “FA” (fig.8). This guarantees that the leaf rests against the centre
stop plate “FA” which, if provided with a rubber cap, avoids banging noi-
ses. In the case where, during the adjustment of the end-of-stroke stop
“VRC”, measurement “Z” (fig.8) becomes greater than 18÷20 mm, the
stop should be turned as in fig.13a.

• On

OPENING (fig.11): The end-of-stroke adjusting screw “VRO” must

come into contact with lever “L” after the leaf has reached the centre stop
plate “FA” (fig.8).

• After completing the adjustment, tighten the locknut on the end-of-stroke

adjustment screws “VRO” together with the screw tightening the end-of-
stroke dowel “VRC”.

• Repeat the same procedure for the second actuator.
• If the foundation case is not orthogonal to the leaf, a 10% adjustment

can be carried out both in clockwise and anticlockwise directions, by
positioning the support bracket and the stop plate as shown in fig. 13b.

9) MOTOR TORQUE SETTING
CAUTION! When using the ARIES mod. control unit with the torque set to
“F4” (maximum torque), it is compulsory to fit the ground stop plates “FA”
both on opening and closing.
The motor torque (antisquash) setting takes place in the control unit. See the
control unit instruction manual. The wiring diagram of the motor is included in the
instructions for use for the relative control unit. This setting must be calibrated
according to the minimum force needed to carry out the complete opening and
closing strokes, and always within the limits provided for by current standards.

WARNING: Check that the impact force value measured at the
points established by the EN 12445 standard is lower than that

specified in the EN 12453 standard.
CAUTION! Excessive torque setting can jeopardise antisquash safety. On
the contrary, insufficient torque setting may not guarantee a correct opening
or closing stroke.

10) EMERGENCY MANOEUVRE
Emergency release is obtained by using the key provided, on the release
unit which is located under the gate, on the protruding section of the lever-
pivot. To release, insert the key in the release triangle and turn it by about
90° in the direction shown by the open-padlock symbol (fig.14). If the leaf is
equipped with an electric lock, release the electric lock as well.
To open/close the gate, push it manually. To restore motor-driven operation,
reposition the gate by aligning it with the lever bearing the lock unit, and turn
the key in the direction shown by the closed-padlock symbol (fig.14) checking
that engagement is correctly restored. Keep the leaf release key (and that of
the electric lock, if any) in a place which is known to the users.
11) AUTOMATION CHECK
Before  making  the  automation  fully  operational,  carefully  carry  out  the
following procedure:
•  Check that all components are tightly fixed.
•  Check  the  correct  operation  of  all  safety  devices  (photocells,  electric
