5) ACTUATOR INSTALLATION

5.1) Preliminary checks
Check that:
• The gate structure is sufficiently sturdy. Also make sure that the actuator
pushes against the leaf reinforced section.
• The leaves move manually and without effort all along their stroke.
• The door stop plates are fitted at the end of both closing and opening
strokes.
• If the gate has not been recently installed, check the wear condition of all
components. Repair or replace faulty or worn parts.
The automation reliability and safety are directly influenced by the state of
the gate structure.
5.2) Installation dimensions
The installation dimensions can be worked out from the table concerning
the respective model (fig. 3) and with reference to the diagram in fig.4.
The diagram in fig. 4 uses the following conventional references:
P Rear bracket fixed to pillar.
F
Leaf fixing front fork.
a-b Dimensions used to determine the fixing point for bracket "P".
C Value of fixing distance between centres.
D
Leaf length.
x Distance from the leaf axis to the pillar edge.
Z
Value always greater than 1.96 in (50 mm) (b - x).
kg
Max leaf weight (see Technical specifications).
a° Leaf opening angle.
5.3) How to interpret the installation measurements (Fig.3)
The "a" and "b" values can be chosen from the table (fig. 3) depending on the a°
opening degrees which are to be obtained. The table highlights the optimum "a"
and "b" values for an opening of a°=90° at constant speed; in this condition, the
sum of the "a" and "b" values is equal to the value of the working stroke "Cu" (fig.2).
If the "a" and "b" values used are too different, the leaf movement is not constant,
and the towing-pushing force and movement speed may vary during mano-
euvring. Maximum "a" and "b" values develop maximum piston force. Warning!
All versions are provided with a ball joint which allows the rod to be lengthened
or shortened by approximately 0.19 in (5 mm), but only if it was fixed using the
dimensions shown in fig. 8 before installation; after installation, this adjustment
allows the rod stroke to be corrected. Fig.9 illustrates the oscillation that the
controllers may show with respect to their horizontal axis. During installation,
scrupulously follow all the phases described below, taking care to protect the
actuator's chromium-plated rod at all times, in order to prevent it from being
damaged by impact or any welding slag.
1) Identify "a - b - a° " in the table in fig.3.
2) Fix bracket "P" (fig.10) to the pillar.
3) Fit the piston in bracket "P".
4) Slacken the slow-down screw (fig.21) using the 0.11in (3mm) Allen wrench
provided.
5) Pull the rod out completely after activating the emergency release (fig.18).
6) Push the rod back in manually by a maximum of 0.39in (10 mm) and tighten
the emergency release (fig.18).
7) Fit fork "F" (fig.8) to the rod.
8) Fully close the gate leaf against the centre stop plate.
9) Keeping the piston level, mark the position for attaching fork (fig.10 ref. "F")
to the leaf.
10) Remove fork "F" from the rod and move the piston sideways.
11) Fix fork (fig.10 ref. "F") to the leaf by means of screws or welding.
12) Reconnect the rod to fork "F" and supply the actuator with power to adjust
the slow-down function.
13) Activate the gate to open.
14) Completely close the slow-down screw by turning it towards the "+"sign (fig.21)
and activate the leaf closing operation. The leaf should stop before arriving
at the closing position.
15) Slacken the adjustment screw towards the "-" sign until obtaining a slow-down
speed which avoids unpleasant slamming noise. Keep in mind that slowing
down can only be obtained during closing, precisely for the last 1.18 in (30mm)

of rod stroke, 0.39 in (10mm) of which account for safety extra-stroke; therefore,
slowing down takes place during the last 0.78 in (20mm) of working stroke.
5.4) Suggestions for particular installations
Fig.5 A recess must be made to house the controller when the leaf is completely
open; the recess measurements are shown in fig. 5.
Fig.7 When the "b" dimension is greater than the values shown in the installation tables,
it is necessary to move the leaf hinge-pivot or make a recess in the pillar, as in fig.6.
5.5) Anchoring of attachments to the pillar
Weld or fix the bracket base supplied to the pillar, check the "a" and "b" measure-
ments and then weld plate "P" to the said base. (fig.10).
• If the pillar is made of masonry, plate "P" must be welded to the metal base
"PF" and deeply anchored by means of suitable hooks "Z" which are to be
welded on the back of the said base (fig. 11a).
• If the pillar is made of stone, plate "P" is welded to the metal base "PF" and can
be fixed by means of four metal screw anchors "T" (fig.11b); if the gate is large,
it is advisable to weld plate "P" to an angle-shaped base (fig.11c).
5.6) Anchoring of attachments to the leaf
Weld or fix fork "F" to the leaf at distance between centres "C" shown in fig. 4,
making sure that the actuator is perfectly level (level "L", fig.10) with respect to
the gate movement plane.
• If the gate is made of metal, the fork can be welded (fig.12a) or fixed using
appropriate screws (fig.12c).
• If the gate is made of wood, the fork can be fixed using appropriate screws
(fig.12b).
6) Ground leaf stop plates
For the actuator to operate correctly, stop plates "FA" must be used during
both opening and closing manoeuvres, as shown in fig.13. The leaf stop plates
must prevent the actuator rod from going to the end-of- stroke position. Fig.
14 specifies the dimensions needed to check the correct actuator installation
both for pushing and towing. The plates must be positioned in such a way as to
maintain a rod stroke margin of approximately 0.393 in (10mm); this is to avoid
possible operation anomalies (suchas a lock-up).
7) ELECTRIC LOCK FITTING
This is needed on all models, as no hydraulic lock is provided either for opening
or closing manoeuvres. The EBP model electric lock (fig.15) consists of a conti-
nuous service electromagnet being anchored to the ground. This device remains
energised throughout the actuator operation time, and allows the catch to stay
lifted when it reaches the closing position,
without opposing any resistance; the catch will drop into position when the gate
has completed the closing cycle. The electric lock can also be used to keep the
block of the gate in case of actuator malfunction or current failure.
8) ELECTRICAL INSTALLATION SET-UP
Set up the electrical installation as shown in fig.16, making reference to the cur-
rent standards for electrical installations. The mains power supply connections
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 having minimum
3x1.5mm (16AWG) cross section and complying with the previously mentioned
2
regulations (UL1015).
Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards. Fig.16 shows the number of connec-
tions and the cross section for power supply cables having a length of approximately
328 ft (100 metres); in case of longer cables, calculate the cross section for the
true automation load. When the auxiliary connections exceed 164 ft (50-metre)
lengths or go through critical disturbance areas, it is recommended to decouple
the control and safety devices by means of suitable relays.
8.1) The main automation components are (Fig.16):
I Type-approved omnipolar circuit breaker with at least 0.118 in (3mm) contact
opening, provided with protection against overloads and short circuits, suitable
for cutting out automation from the mains. Place, if not al ready installed, a type-
approved differential switch with a 0.03A threshold just before the automation
system.

(optional).

Important: Before electrically activating the actuator, remove bleed screw "S" (fig.
17) which is positioned under the articulated joint block and keep it for any later
reuse. Only remove bleed screw "S" when the actuator is installed. Fit the release
cover block provided, as illustrated in the drawing (fig.18). "Warning! For the
