during manoeuvring. 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 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 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 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 30mm of rod stroke, 10mm of which account for safety extra-
stroke; therefore, slowing down takes place during the last 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"
measurements 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
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 continuous 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,
INSTALLATION MANUAL
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
Lay out the electrical installation (fig.16) 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 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
mentioned regulations (e.g.: a H07 RN-F cable with 3x1.5mm
Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards. Fig.16 shows the number of
connections and the cross section for power supply cables having a length
of approximately 100 metres; in case of longer cables, calculate the cross
section for the true automation load. When the auxiliary connections
exceed 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 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.
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 and RG58 cable.
M Actuator.
E Electric lock.
Fte Pair of external photocells (emitter section).
Fre Pair of external photocells (receiver section).
Fti Pair of internal photocells with CF posts (emitter section).
Fri Pair of internal photocells with CF posts (receiver section).
T 1-2-4 channel transmitter.
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 connection of the accessories, please refer to
the relevant instruction manuals. The type of control boards and accessories
must be suitable for the intended use and in compliance with the current
safety standards"
9) MANUAL OPENING
In case of emergency, for example when the electrical power is discon-
nected, open the electric lock by means of the appropriate key to release
the gate, and open the leaf manually; you may also reach the release knob
to facilitate the manoeuvre. In order to get access to the release knob, move
the small cap in the direction indicated by the arrow (fig.18) to reveal the
lock, insert the key, turn it clockwise by 90° and lift the entire release cover
by pulling with the key. The knob must be allowed to turn as far as possible
in the direction indicated by the arrows.
OPEN to release: the gate can be opened manually with ease.
CLOSE to lock: turn the knob clockwise until it is completely locked, and
so restore the actuator electrical operation.
10) PUSHING FORCE ADJUSTMENT
For safety reasons, proceed as follows in order to get access to the
adjustment valves:
• Move the release cover block cap in the direction indicated by the arrow
(fig.19) to reveal the lock.
• Insert the key, turn it clockwise by 90° and lift the entire block by pulling
with the key. Unscrew the two fixing screws and remove the entire
release system.
• The pushing force is adjusted by two valves marked with the writing
"Close" and "Open" respectively, which are used to adjust the closing
and opening pushing force (fig.19).
Turn the valves towards the "+" sign to increase the force transmitted;
turn the valves towards the "-" sign to reduce the force. To achieve
proper antisquash safety, the pushing force must be slightly higher than
that needed to move the leaf during both closing and opening manoeuvres;
the strength, which is measured on the leaf edge, must never exceed the
2 cross section and complying with the previously
ENGLISH
2 section).
