Adjustment of the Anti-Crushing Device
Perform the following steps in the order given
to ensure trouble-free gate operation.
5.1
ADJUSTMENT OF ANTI-CRUSHING SYSTEM
5.2
ADJUSTMENT OF INTERNAL TRAVEL STOP
SCREWS (MODEL 760 CR ONLY)
5.3
ADJUSTMENT OF DECELERATION RAMP
(MODEL 760 CR ONLY)
The FAAC 760 operators (with or without
deceleration ramp) are equipped with an
anti-crushing safety system that stops the
gate should an obstacle be encountered.
Adjust the anti-crushing system’s torque
according to applicable standards, but
should not exceed 15 Kg of force at the
outer edge of the gate.
Use a linear dynamometer to ensure that
force at the outer edge of the gate is
measured accurately.
Turn the by-pass valve screws as shown in fig.
19 to set the anti-crushing system’s threshold.
–
The red screws adjusts torque for anti-
clockwise leaf movement.
–
The green screw adjusts torque for
clockwise leaf movement.
Turn the screws clockwise to increase torque.
Turn the screws anti-clockwise to decrease
torque.
706 operators (model CR) have adjustable
deceleration ramps both in opening and
closing positions for use with gates which
open to angles of 90° or more.
Deceleration starts at 10° from the setting of
the internal travel stop adjusting screws (ref.
A–B, fig. 20/a).
