1) GENERAL OUTLINE

The SUB hydraulic controller provides the ideal solution for underground
hinge-pivot installations, as it brilliantly solves aesthetic automation
problems. The SUB actuator consists of a perfectly sealed single block,
containing a hydraulic control unit and a jack, which provides a hidden
underground installation without any hydraulic connections. The gate is
kept closed by an electric lock, or by a hydraulic lock on the SUB versions
supplied with it. The versions with slow-down functions avoid unpleasant
slamming noise when the gate is brought to the final opening and closing
stages. The pushing force can be adjusted with extreme precision by
means of two by-pass valves which provide antisquash safety. The end-of­stroke operation is electronically set by a timer on the control panel. The
emergency release, activated by the proper key supplied, can be easily
reached after removing the appropriate cap found on the cover.

6) ACTUATOR INSTALLATION

6.1) Preliminary checks

Check that:

- The leaf structure is sturdy and rigid.

- The upper hinge is in working order and possibly adjustable.

- A hole can be dug to lay the case under the hinge-pivot, or to one side
of the hinge-pivot for slide arm installation.

- The leaf ground stop plates are fitted.

- Repair or replace all faulty or worn components.

Fig.3 illustrates an exploded view of the installation. Automation reliability
and safety are directly affected by the condition of the gate structure.

6.2) Electrical installation setup

Set up the electrical installation as shown in fig.4, making reference to the
current standards for electrical installations, i.e. CEI 64-8, IEC364, complying
with HD384 and other national standards. Keep the mains supply connections
definitely separate from the service connections (photocells, electric edges,
control devices, etc.).

WARNING: For connection to the mains, use a multipolar cable of the
type provided for by the previously mentioned standards (for example,
if the cable is not protected, it must be at least equal to H07 RN-F,
whereas if it is protected it must be at least equal to H07 VV-F with a
3x1.5 mm2 cross section).

Connect the control and safety devices in compliance with the previously
mentioned installation standards. Fig.4 shows the number of connections

D811036_03

212

D811036_03

D8110

and the cross section for power supply cables about 100-m long; for greater
lengths, calculate the cross section needed for the true automation load.

6.3) Main automation parts (Fig.4):
I) Type-approved adequately rated omnipolar circuit-breaker with at

least 3-mm contact opening, provided with protection against
overloads and short circuits, suitable for cutting out automation
from the mains. If not already installed, place a type-approved
omnipolar circuit-breaker with a 0.03A threshold just before the
automation system.

Qr) Control panel and incorporated receiver.
SPL) Preheating board for operation with temperature lower than 5°C

(optional).

S) Key selector.
AL) Blinker with tuned antenna.
M) Controller.
E) Electric lock.
Fte) External photocells (emitting section).
Fre) External photocells (receiving section).
Fti) Internal photocells with CF posts (emitting section).
Fri) nternal photocells with CF posts (receiving section).
T) 1-2-4 channel transmitter.
RG58) Cable for antenna.
D) Connector block.



The connector block (fig. 6) must always be positioned higher
than the motor. In fact, as the controller is perfectly sealed, the

tank is made to breathe through the actuator supply cable.

6.4) Cementation of the foundation case (under the hinge-pivot)

The case must be cemented under the hinge-pivot, keeping in mind that the
actuator bearing shaft must be perfectly aligned to the leaf rotation axis. If
the gate is provided with fixed hinges, disassemble it and remove the lower
hinge. If the leaf is high enough 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 is provided with adjustable hinges,
remove the lower hinge, loosen the upper one and move the leaf to the
side. If the gate has been newly manufactured, fit an upper hinge which
can be adjusted.

- Dig a foundation hole having the dimensions shown in fig.5.

- Provide a drainage pipe (fig.6) for rainwater in order to prevent stagnation
inside the foundation case. Lay a raceway for the power supply cable as
far as connector block “D”

- Lay a strong foundation on the bottom (fig.5) where to bury the hooks of
foundation case “P”. The dimensions for positioning plate “P” are
defined in fig.5. Let the cement harden for the time needed.

- Rest the actuator on base “P”, with its shaft perfectly aligned to the leaf
axis (fig.7), and weld four angle bars “A” in correspondence with the four
corners of the actuator centring base. The minimum dimension between
the pillar and rotation shaft axis is shown in fig.6.

- Assemble the foundation case by fixing its two half sections together by
means of the screws supplied (fig.8), and fixing small plate “PI” to the
back. Position the box around the actuator, so that small plate “PI” (fig.

8) fits around the shaft, and the edge of the box protrudes above the
ground by about 10mm (fig.6). Position cover “CE” (fig.3) on the box and
fix its corners with 2 screws.

- Fill the rest of the hole with concrete.

6.5) Cementation of the foundation case (to one side of the hinge-pivot)

Installation with slide arm (to one side of the hinge pivot). This is advisable
when you want to avoid disassembling the existing gate leaf. Area “A”
highlighted in fig.9 corresponds to a right-angled triangle having a side of
approximately 200mm, where the actuator axis can be laid in order to allow
the leaf to open by at least 90°.

- The drive arm provides a distance between centres between grooved
bush “B” and sliding roller “R” of up to 380mm.

- Bush “B” must be welded to the drive arm with the leaf completely
closed, the roller must be inserted into slide “S” taking into account the
safety degrees shown on small card “CA” (fig.11). For slowed-down
versions, also take into account the slow-down degrees (fig.13).

- Slide “S” (fig.9) can be welded or fixed with screws both underneath and
to the side of the leaf. The position of the slide is to be identified by
marking on the leaf the spots reached by sliding roller “R” both during
closing and opening, Having identified the mid-point between the two
markings made previously, align the mid-point of slide “S” and fix it
tightly. If slide “S” is shorter than the distance between the two markings
on the leaf, this type of installation is not possible. Keep in mind that, the

nearer slide “S” is to the leaf rotation pivot, the greater will the leaf speed
be. Having identified the actuator position, proceed to cementing the
foundation case as described in paragraph 6.4.

7) BEARING FOUNDATION CASE
Two bearing foundation case models - CPS for SUB and CPS G for SUB
G (fig.10) - are available. Having installed the bearing case, the gate

becomes operational even without mounting the actuator, which can be
inserted later. In case of any maintenance needed, this type of case allows
the actuator to be removed without disassembling the gate leaf. Should the
CPS mod. bearing foundation case be used, refer to the respective manual
for the positioning procedure.

8) LEAF MOUNTING

With the actuator in its final position, proceed as follows.

- Prepare a U-shaped shoe (fig.3) where the leaf is to be inserted and then
fastened in its correct position by welding small plate “PS” to it.

- Position grooved bush “B” in the actuator shaft.

- Temporarily fasten the shoe to the leaf: mount the leaf in its completely
closed position, placed over the actuator shaft and perfectly aligned to
the rotation axis.

- Before welding bush “B” to the U-shaped shoe, the right fixing point must
be found. To determine the correct point, proceed as described below.

WARNING: Do not weld bush “B” directly to the leaf. Do not weld the
grooved bush to the actuator output shaft.

8.1) Version without slow-down function

- Release the jack with key “CS” supplied, in the way shown in fig.18.

- With the help of pliers, completely rotate the output shaft in the direction
of gate closing along its entire stroke.

- Arrange small card “CA” (fig.11) by positioning point “M” in
correspondence with the arrow in the casting.

- Rotate the shaft and bring point “G” (right-r.h. or left-l.h.) in
correspondence with the arrow.

- Protect the actuator from any metal spots during the subsequent
welding phase.

- The bush can now be welded to the shoe with the leaf mounted in the
gate closed and stopped position. Disassemble the shoe to weld bush
“B” all the way around its circumference.

- Any small defects in levelling foundation plate “P” can be corrected by
means of adjustment dowels “GR” (fig.3).

- Place the gate stop on opening in the required position; however, the
gate stop must maintain an extra rotation of at least 5° for safety, in order
to prevent the rack from reaching its end of travel.

NOTE: The rotation degrees of the SUB R versions are highlighted in fig.
12; in the case of versions without slow-down function, consider the slow­down angles (25°+25°) as normal speed. For the SUB G versions, take into
account a total rotation of 185°. For effective 180° openings, the safety
margin is 2.5° both on closing and on opening.

8.2) Version with slow-down function

The versions provided with slow-down function need particular attention in
identifying the fixing point of grooved bush “B” (fig.3). It is advisable to use
the actuator in a symmetrical way; fig.12 shows the 130 degrees of total
rotation of an ordinary actuator, divided into the various phases. By way of
example, fig.13 shows the correct operation method for an actuator
carrying out a leaf opening manoeuvre of 90°, that is 20°+ 20° for safety, 70°
for normal stroke and 10°+ 10° for slow-down. In order to obtain the angles
described, use small card “CA” on the “SUB R mod.” side (fig.11).
WARNING: For effective opening manoeuvres of less than 90°, slow-down
cannot be obtained in both directions. You need to decide beforehand
whether to have slow-down on closing or opening, taking into account that
slow-down begins to happen in the last 25°- 30° of shaft rotation, both on
opening and closing (fig.14). Having determined the correct angle for fixing
the grooved bush, fix it in the way described in paragraphs 8 - 8.1.
NOTE: For the SUB GR versions, take into account a total rotation of 185°,
out of which: 2.5°+ 2.5° for safety, 25°+ 25° for slow-down and 125° for
stroke at normal speed. This provides a maximum rotation of 180°.

8.3) Slow-down adjustment (R versions only)

Slow-down adjustment screws “VR” are highlighted in fig.15, and can be
adjusted by means of a 3-mm Allen wrench. This must be turned clockwise
to make the movement slower and anticlockwise to make is less slow.
Adjust the slow-down speed so as to prevent the leaf from slamming
when it stops.
