ARM2000 Series
DESCRIPTION
The ARM2000 automated system for swing gates is an electro-
mechanical non-reversing actuator that transmits motion to the leaf
via a worm screw system.
The actuator is available in 12 Vdc and 230 Vac versions. All ver-
sions are equipped with closing limit switches.
The non-reversing system ensures the leaf is mechanically locked
when the motor is not operating. A convenient and safe release
system with customised key makes it possible to manually move
the leaf in the event of a malfunction or of a power failure.
ATTENTION:
The correct operation and the declared specifica-
tions only apply if TAU accessories and safety de-
vices are used.
In the absence of a mechanical clutch, the use of
a control unit with an adjustable electronic clutch,
or the installation of a sensitive edge, is required in
order to ensure crush-proof safety.
The ARM2000 automated system was designed and
built for controlling vehicle access. Avoid any other
use whatever.

Notes:
• Use suitable tubes and/or hoses to lay electric cables
• Choose short routes for cables and keep power cables sepa-
rate from control cables.
Preliminary checks
Prior to installing the automation, make all structural modifications
in order to ensure safety distances and protect and segregate ar-
eas in which people may be exposed to the risk of crushing, shear-
ing, dragging or similar dangers.
• Make sure the existing structure is sufficiently sturdy and stable;
• the mechanical parts must conform to the provisions of Stand-
ards EN 12604 and EN 12605;
• leaf length in compliance with the actuator specifications;
• regular and uniform movement of the leaves, without any fric-
tion and dragging during their entire travel;
• stiff hinges in good conditions;
• presence of both opening and closing mechanical limit stops;
• presence of an efficient earthing for electrical connection of the
actuator.
Perform any necessary metalwork job before installing the auto-
mated system.
The condition of the gate structure directly affects the reliabil-
ity and safety of the automated system.
Installation dimensions (fig.4)
Determine the fitting position of the actuator with reference to fig.4.
Check with care if the distance between the open leaf and any ob-
stacles (walls, fences etc.) is higher than the actuator dimensions.

If the pillar dimensions or the hinge position do not allow the in-
stallation of the actuator, a niche on the pillar, as shown in Fig. 5,
should be created in order to maintain the A dimension as deter-
mined. The niche should be dimensioned in such a way to enable
easy installation, actuator rotation and operation of the release de-
vice. The mounting brackets are designed to enable small adjust-
ments in both directions (fig.5A). In any case, always refer to the
measurements shown in the table.
Please keep to the values given in the table and oil the gate’s
hinges.
1_ Fix the rear bracket in the position determined before. In the
event of iron pillar carefully use n°4 Ø 6,3 mm self-drilling
screw (fig.6). In the event of brick pillar (fig.7), use n°4 M8 bolts
(after you have assembled it, fig.7A).
During the fastening operations, check if the bracket is
perfectly horizontal by means of a level.
WARNING - In case of large gate leaves and /or
closed design leaves other than the installation of
an electro lock it is suggested to strengthen the fas-
tening of the back bracket (weld the steel parts in-
stead of using screws to assemble the bracket, use
M10 instead of M8 screws, weld the bracket onto the
pillar, etc.).
