control devices etc.).
Warning! For connection to the mains, use a multipolar cable having minimum
3x1.5mm cross section and complying with the previously mentioned
2
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).

AL Blinker with tuned antenna and RG58 cable.
M Actuator.
E
Electric lock.
Fte
Pair of external photocells (emitter section).

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 disconnected,
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 limits set out by the
current national standards. Under no circumstances whatsoever must
the by-pass valves be fully closed. Complete the adjustments and restore
the release system, taking care to refit the packing rings and washers. The
actuator is not provided with electrical limit switches. Therefore the motors
switch off at the end of the operation time set by the control unit. The said
operation time must last approximately 2-3 seconds after the moment when
the leaves meet the ground stop plates.
11) COVERING ELEMENT POSITIONING
Covering element "C" for all models can become left or right-handed by
reversing the position of cap "T" (fig.22), taking care to keep the water drainage
channel always at the bottom.
12) AUTOMATION CHECK
Before the automation device finally becomes operational, scrupulously check
the following conditions:
• Check that all components are tightly fixed.
• Check that all control devices (photocells, pneumatic edge etc) operate
correctly.
• Check the emergency manoeuvre command.
• Check the opening and closing operations using the control devices
provided.
• Check the normal (or personalised) function control logic in the control unit.

13) AUTOMATION OPERATION
Since the automation system can be remotely controlled by means of a radio
control device or a Start button, all safety devices must be frequently checked
in order to ensure their perfect efficiency. In the event of any irregular operation,
request immediate assistance from qualified personnel.
Children must be kept at a safe distance from the automation operation
area.
14) CONTROL
Various types of control are provided (manual, radio control, magnetic
card access control etc.) depending on the installation requirements and
characteristics. (See the specific instructions for the various control systems).
The installer undertakes to instruct the user about the correct automation
operation, and also point out the operations required in case of emergency.
15) MAINTENANCE
Before carrying out any maintenance to the controller, disconnect the system
power supply. Periodically check the system for oil leaks.
Topping up should be carried out as follows:
a) Remove the release system (see fig.19).
b) Keeping the gate closed, top up using the prescribed oil until its level reaches
above the piston pipe (fig.20 ref. "P"). To check this, insert a screwdriver
through the release cover block fixing hole, so as to reach the piston pipe and
make sure it is oiled.
c) Refit all the component paying attention to the seals. Check all automation
safety devices.
When any operational malfunction if found, and not resolved, disconnect
the system power supply and request the assistance of a qualified technician
(installer).
If the power supply cable is damaged, it must be replaced directly by our
company or our technical service department or by a technician having
similar qualification so as to avoid any risks. When automation is out of order,
activate the manual release knob to allow the manual opening and closing
operations to be carried out by means of the electric lock.
16) MALFUNCTIONS AND REMEDIES
16.1) Faulty operation of the actuator
Using an appropriate instrument, check that the ends of the actuator are
supplied with voltage after the opening or closing command is given. If the
motor vibrates but does not turn, the causes could be as follows:
• Wrong connection of common wire C (always light blue).
• No connection between the drive capacitor and the two drive terminals.
• If the leaf movement is opposite to what it should be, reverse the motor drive
connections in the control unit.
Leaf stops: when the operation time is insufficient, the leaves may not complete
their strokes. In that case, slightly increase the operation time setting in the
control unit.
16.2) Faulty operation of the electrical accessories
All faulty control and safety devices can cause abnormal operation or
automation block. If the control unit is provided with a self-diagnosing system,
identify the fault. In case of malfunction, it is advisable to disconnect and bridge
all the automation devices one by one, if necessary, until the faulty device is
identified. After replacing or repairing it, restore all the devices which were
previously disconnected or bridged. For all devices installed, refer to their
respective instruction manual.
Warning: the above operation must be carried out by qualified personnel.
During maintenance, the gate operational area must be appropriately indicated
and closed off, in order to avoid any danger to persons, animals and property.
Warnings: Correct controller operation is only guaranteed when the data
specified in this manual are respected. The company cannot be held responsible
for any damage caused by failure to observe the standards on safety, installation
and good technical practice, as well as the directives specified in the present
manual.
