391 AUTOMATED SYSTEM
The 391 automated system consists of a non-reversing electro-
mechanical operator available in two versions:
• 391 E with built-in control unit
• 391 without control unit
The operator was designed for automating the opening of gates
with one or two leaves, with maximum length of 2.5m.
A handy, safe releases system, with personalised key, moves the
leaf in case of a power cut or fault.
The two articulated arms are designed for moving gates with
very large pilasters. The distance between the hinge and the
gearmotor securing point can be up to 220 mm. Thanks to the
special geometry of the two arms, all possible shearing points
have been eliminated.
• Correct operation and the specifications declared
in these instructions can be obtained only with
FAAC
accessories and safety devices.
• To make an installation conforming to current safety
regulations, the absence of a mechanical anti-crushing
clutch, means that a control unit with an adjustable
electronic clutch device is necessary.
• The 391 automated system was designed and built for
controlling vehicle access - do not use for any other
purpose.

For leaves with a length L>2m, an electric lock must be installed
to guarantee locking the leaf.

The weight P of the leaf is a function of the length L. Check if your
leaf is in the zone shown in the graph underneath.
