1. DESCRIPTION
The ARM3000 swing gate operator is an electro-mechanical, irreversible 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 closing 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 tampering. 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 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 order to ensure crush-proof safety.
The ARM3000 swing gate operator has been designed and built for controlling vehicle access. It is not intended as a high de-
gree 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 separate 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 Standards EN 12604 and EN 12605;
• leaf length in compliance with the actuator specifications;
• regular and uniform movement of the leaves, without any friction 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 operator.
The condition of the gate structure directly affects the reliability 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.
