2) GENERAL INFORMATION
Electromechanical operator designed to automate residential-type gates.
The gearmotor keeps the gate locked on closing and on opening, without
needing an electric lock for leaves up to 2 m long. For leaves ranging
between 3m and 5m long, the electric lock becomes indispensable.
The operator is provided with an electronic torque limiter. It must be
controlled by an electronic control panel provided with torque setting.
The operator is provided with an obstacle detection system complying
with EN12453 and EN 12445 standards.

**In the event of a power supply at 60Hz, the maximum weight of leaf dedu-
ced from the diagram "Length" vs "Weight" is to be reduced by multiplying
it by the coefficient k = 0.7
Pmax 60Hz = Pmax 50Hz x 0.7
4) TUBE ARRANGEMENT Fig. A
Install the electrical system referring to the standards in force for electrical
systems CEI 64-8, IEC 364, harmonization document HD 384 and other
national standards.
Warning! For actuator wiring and accessory connection, refer to the
relevant instruction manuals. The control panels and accessories must

Should the opening or closing direction be incorrect, it is possible to invert
the connections of operation 1 and operation 2 on the control board.
The first command after an interruption of the power supply should be
an opening manoeuvre.

6) PILLAR FASTENINGS INSTALLATION DISTANCES Fig. B
6.1) How to read the installation distance tables
Select "a" and "b" according to the angle in degrees α° that the gate has
to open.
If there is too large a difference between "a" and "b", the leaf will not travel
smoothly and the pushing or pulling force will fluctuate during its stroke.
To respect the opening speed and ensure the controller operates correctly,
it is best to keep the difference between "a" and "b" as low as possible.
The table has been worked out for A40 mm thick medium-size gate.
Always check that there is no possible collision between the gate and
the operator.
7) FASTENING OF FITTINGS TO PILLAR Fig. C
8) MOTOR CORRECT ASSEMBLY Fig. D
NOTES The motor must be assembled correctly as in figure D.
The operator's incorrect assembly causes the actuator and performance
in general to fail the IP rating.
9) CORRECT HEIGHT FROM GROUND TO COMPLY WITH Fig. E
10) ATTACHING MOTOR TO FASTENING ON PILLAR Fig. F
NOTES: the nut must not be fixed inside the hexagonal seat but only until
it touches the half-body. The nut must not put pressure on the half-body.
11) MAXIMUM TILT Fig. G
12) CORRECT INSTALLATION Fig. H
Correct installation entails maintaining a rod stroke margin of approx.
5-10 mm to avoid possible trouble with operation.
13) FASTENING OF FITTINGS TO LEAF Fig. I
IMPORTANT: THE FRONT BRACKET MUST BE FITTED WITH THE SLOTS
FACING DOWN (AS IN THE FIGURE)
Align the front and back brackets as in Fig. I.
14) OPERATOR ATTACHMENT ON DOOR Fig. J
NOTES: the nut must not be fixed inside the hexagonal seat but only
until it touches the joint attachment. The nut must not put pressure on
the joint attachment.

16) TIPS FOR SPECIAL INSTALLATIONS Fig. L.

Fig. L shows the minimum recess dimensions.
If distance "b" is greater than the values given in the installation tables:
- create a recess in the pillar Fig. M
- move the leaf so that it is flush with the pillar Fig.N.
17) LEAF STOPS AT GROUND LEVEL Fig. O
For the actuator to work properly, it is advisable to use stops "Fig. O Rif. 1"
to stop the leaves both when they are open and closed, as illustrated in fig.
The leaf stops must prevent the actuator rod from reaching the end of
its travel.
18) MANUAL OPENING (See USER GUIDE -FIG.Y,Y1-).
19) ELECTRIC LOCK (Fig. Y)
WARNING: In the case of leaves longer than 2m, it is indispen-
sable to install a solenoid latch.
For electric lock connection, the optional board is required (refer
to the appropriate instruction).
