DESCRIPTION
The ARM2000 swing gate operator is an electro-mechanical, ir-
reversible operator that transmits motion to the leaf via a worm
screw system.
The operator is available in 18V DC and 230V AC versions. All
versions are supplied with adjustable closign mechanical stopper.
The irreversible operation ensures the leaf is mechanically locked
when the motor is not operating, but it is not intended as a high
degree security deterrent against intrusion attempts and/or tam-
pering. A convenient and safe release system with customised key
makes it possible to manually move the leaf in the event of a mal-
function or of a power failure.
ATTENTION:
The correct operation and the declared specifications
only apply if TAU accessories and safety devices 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 or-
der to ensure crush-proof safety.
The ARM2000 swing gate operator has been designed
and built for controlling vehicle access. It is not in-
tended as a high degree security deterrent against
intrusion attempts and/or tampering. 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 operator, make all structural modifications in
order to ensure safety distances and protect and segregate areas
in which people may be exposed to the risk of crushing, shearing,
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;

ARM2000 Series
• 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 opera-
tor.
The condition of the gate structure directly affects the reliabil-
ity and safety of the gate operator.
Installation dimensions (fig.4)
Determine the fitting position of the operator with reference to pic. 4.
Make sure space between the open leaf and any obstacles (walls,
fences etc.) allows the operator to fit.

VALUES
When distance "C" is greater/smaller than 20 mm, increase/de-
crease distance "B" by the difference (e.g.: if C = 25mm, increase
"B" by 5mm), making sure that it does not exceed the limits shown
in the chart.
Note: to work correctly, the angle formed by the ac-
tuator and the gate (Y°, pic. 4) must be ≥ 2° both with
the gate completely closed and completely open.
Note: for a quick opening and optimum closed-hold-
ing position (gates with an electrical lock), use the
maximum distance "B" shown in the chart.
If the pillar dimensions or the hinge position do not allow the in-
stallation of the operator, a niche on the pillar, as shown in pic.
5, should be created in order to maintain the A distance as deter-
mined. The niche should be dimensioned in such a way to enable
easy installation, actuator rotation and operation of the release
device. The mounting brackets are designed to enable small ad-
justments in both directions (pic. 5A), it is possible to use the two
multipoint brackets overlapped (pic. 5B: in this case the only holes
to be used are the 3 highlighted, according to the direction of the
leaf movement). 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 weld directly the bracket or use 4
suitable screws (pic. 6). In the event of brick pillar (pic. 7), use 4
suitable bolts (after you have assembled the bracket, pic. 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 fastening of the
back bracket (weld the steel parts instead of using
screws to assemble the bracket, use steel anchors
instead of the dowels, weld the bracket onto the pil-
lar, etc.).
