the power supply mains.

• Check that earthing is carried out correctly: connect all metal parts for
closure (doors, gates etc.) and all system components provided with an
earth terminal.

• Fit all the safety devices (photocells, electric edges etc.) which are
needed to protect the area from any danger caused by squashing,
conveying and shearing, according to and in compliance with the
applicable directives and technical standards.

• Position at least one luminous signal indication device (blinker) where
it can be easily seen, and fix a Warning sign to the structure.

• The Company declines all responsibility with respect to the automation
safety and correct operation when other manufacturers’ components
are used.

• Only use original parts for any maintenance or repair operation.

• Do not modify the automation components, unless explicitly authorised

by the company.

• Instruct the product user about the control systems provided and the
manual opening operation in case of emergency.

• Do not allow persons or children to remain in the automation operation area.

• Keep radio control or other control devices out of children’s reach, in

order to avoid unintentional automation activation.

• The user must avoid any attempt to carry out work or repair on the
automation system, and always request the assistance of qualified
personnel.

• Anything which is not expressly provided for in the present instructions,
is not allowed.

2) GENERAL OUTLINE

This controller is suitable for residential use and has been designed for
swing gates with particularly large gate posts. The drive arm, built with a
special anti-shearing shape, allows the leaves to be moved when the
controller is considerably out of place with respect to the fulcrum of the
leaves. The non-reversible electro-mechanical gearmotor maintains the
stop during closing and opening. The release lever, fitted in each controller

and situated inside the door fitted with personalised key, allows the manual
manoeuvre to be easily carried out.
WARNING! The installation, the maintenance and the repair should be
done by responsible and qualified persons with an updated knowledge of
the current safety standards. It’s strictly forbidden to service the automation
when the power is on.
ATTENTION! The JOINT model controller is not equipped with mechanical
torque adjustment. It is compulsory to use a control panel of the same
manufacturer, in compliance with the basic safety requirements of directives
73/23/CEE, 89/336/CEE, 89/37/CEE equipped with appropriate electric
adjusment of the torque.

4) INSTALLATION OF AUTOMATION

Preliminary checks
Check:

- That the structure of the gate is rigid and strong enough. The fixing

position should be assessed according to the structure of the leaf. In any
case, the manoeuvring arm must push against a reinforced point in the
leaf (fig.2).

- That the leaves move manually for the whole of their stroke. If a new gate

is not being installed, check whether its components are worn.
Repair or replace any worn or damaged parts.
Automation reliability and safety are directly influenced by the condition
of the gate’s structure.

5) FIXING OF SUPPORTING PLATE (Fig.2)
The controller is supplied complete with anchoring bracket and lever arm.
Once the reinforcement point of the leaf has been identified with the gate
closed, draw an imaginary horizontal line from the centre of the reinforcement
point to the gate post (fig.2). Position the anchoring bracket according to the
values given in fig. 2 for openings of up to 90° or in fig.3 for openings greater
than 90° up to a maximum of 125°.
The bracket fixing position must be flat and parallel to the leaf. Use screws
or expansion bolts which are suited to the type of gate post. If the surface
of the gate post is not regular, use expansion bolts with studs so that the
parallel plate of the leaf can be adjusted (fig.4).

- Fasten the gearmotor to the gate post using the 4 screws, pointing the

gearmotor to the left or the right (fig.5).

- Assemble the lever arm as shown in fig.6.

DX= assembly on the right leaf
SX= assemby on the left leaf
Choose the most suitable position of ‘F’ bracket for the fastening to the leaf.

- Insert the square of the first lever in the output shaft of the gearmotor and

fasten it (fig.7).

- Release the controller by activating the release lever so that the arm can

move easily (see the “EMERGENCY MANOEUVRE” paragraph).

- The correct position for the controller arm is shown in fig.8. The leaf

fixing point “A” can be identified by positioning the arm so that it is in
accordance with the distance shown in fig.8.

- Fix the angular towing bar “A” to the leaf by welding or using screws.

- With the controller released, check the correct movement of the arm.
