Guide for the installer
Page
Thank you for choosing our product. FAAC is sure that it will give you
all the performances you are looking for. All our products are the
result of a long experience in the field of the automated systems.
In the middle of the handbook you will find a detachable
brochure with the images for the installation.
The
770
automation system for swing gates is a geared motor. It is
designed for underground installation and therefore does not alter
the appearance of the leaf.
The foundation box of the automation system comes ready to
take an operator.
The
770
electromechanical operator is irreversible, so it ensures
a mechanical stop and eliminates the need to install an electric
lock.
IMPORTANT NOTES FOR INSTALLER
Before starting the installation of the operator read this manual
completely.
Keep this manual for future reference.
Smooth operation and specifications are obtained only declared
following the directions given in this handbook and with acces-
sories and safety devices FAAC.
The lack of a mechanical clutch device requires to ensure an
adequate level of security automation, the use of a central control
device with an electronically controlled clutch.
The automation was designed and built to control vehicular ac-
cess. Avoid any other use.
The operator can not be used to handle emergency exit routes
or gates installed on emergency (escape routes).
If there is built-in anti motorize from a door to the walkway is requi-
red to add a safety switch on the door, connected on the entry of
STOP, to inhibit the operation of automation with door open.
Everything that is not expressly stated in this manual is not al-
lowed.

2. MAXIMUM USE CURVE
The curve makes it possible
to establish maximum work
time (T) according to use
frequency (F).
With reference to IEC 34-1
standard, the 770 gearmotor
operating at S3 service, can
function at a use frequency
of 30%.
To ensure efficient operation,
operate in the work range
below the curve.
The curve is obtai-
ned at a temperatu-
re of 20°C. Exposure
to the direct sun rays
can reduce use fre-
quency down to 20%.
C
alCulation
of
use
frequenCy
The percentage of effective work time (o closing) compa-
red to total time of cycle (o c pause times).
Calculation formula:
Ta + Tc
% F = ––––––––––––––––––– X 100
Ta + Tc + Tp + Ti
where:
Ta = opening time
Tc =
closing time
Tp = pause time
Ti = time of interval between two complete cycles

To lay electrical cables, use adequate rigid and/or flexible
tubes.
Always separate low voltage accessories from those ope-
rating at 230 V~. To avoid any interference, always use
separate sheaths.
4. INSTALLATION OF THE AUTOMATION SYSTEM
4.1. PRELIMINARY CHECKS
To ensure trouble-free operation, make sure that the gate (whether
existing or yet to be installed) has the following specifications:
max. weight of single leaf 500 Kg;
max. length of single gate leaf 3.5 m with levers for 110° ope-
ning;
max. length of single gate leaf 3 m with levers for 180° opening;
max. length of single gate leaf 2.5 m with levers for 140° ope-
ning;
strong and rigid leaf frame;
