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 3 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 end-of-stroke operation is controlled by two magnetic limit devices.
The operator is provided with an obstacle detection system complying with
EN12453 and EN 12445 standards.
The following optional accessories are available on request:
- Buffer battery kit mod. BT BAT
Allows operation of the automation even when there is no mains power
supply for a short period of time.

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. The
optimum "a" and "b" values for 92° opening at constant speed are highlighted.
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 a 40 mm thick medium-size gate. Al-
ways check that there is no possible collision between the gate and the
operator.

8) POWER CABLE Fig. D
The board power supply cable must be of the H 05 RN-F type or equivalent.
The equivalent cable must guarantee:
- permanent outside use
- maximum temperature on the cable surface of +50° C
- minimum temperature of -25° C

11) CORRECT INSTALLATION Fig. G
Correct installation entails maintaining a rod stroke margin of approx. 5-10
mm to avoid possible trouble with operation.
12) FASTENING OF FITTINGS TO LEAF Fig. H
IMPORTANT: the front bracket must be fitted with the bush collar protruding
UPWARDS (Fig. G Ref. 1).

14) CLOSING LIMIT DEvICE ADjUSTMENT Fig. j
ATTENTION! To avoid braking the limit switch cable, tighten screw A keeping
the wire B well tightened (as shown in Fig. J Rif. 3).

16) DIMENSIONS Fig. L
17) TIPS FOR SPECIAL INSTALLATIONS Fig. M, N, O.
With the leaf fully open, create a recess to accommodate the operator.
Fig. M gives the minimum dimensions of the recess .
If distance "b" is greater than the values given in the installation tables:
- create a recess in the pillar Fig. N
- move the leaf so that it is flush with the pillar Fig. O.
18) LEAF STOPS AT GROUND LEvEL
For the actuator to work properly, it is advisable to use stops "Fig. P Rif. 1" to
stop the leaves both when they are open and closed, as illustrated in Fig.
P. The leaf stops must prevent the actuator rod from reaching the end of
its travel.
19) MANUAL OPENING (See USER GUIDE -FIG.Y-).
20) ELECTRIC LOCK
WARNING: In the case of leaves longer than 3m, it is indispensable
to install a solenoid latch.
For electric lock connection, the optional board is required (refer to the
appropriate instruction).
