The curve makes it possible to determine
maximum operating time (T) on the basis of
duty cycle (F).
For example, 760 CBAC/SB operators can
run continuously at a duty cycle of 60%.
To ensure smooth running, operation should
be kept within the area below the duty cycle
curve.
Important Note:The curve has been
plotted for operation at 24 °C.
Allow a reduction of up to 20% in the duty
cycle at higher ambient temperatures.
Calculating the Duty Cycle
The duty cycle is the percentage of actual
operating time (opening and closing)
compared with total cycle time (opening +
closing +stationary + internal).
TA + TC
%F = x 100
TA + TC+TP+TI
TA : opening time
TC : closing time
TP : stationary time
TI : length of interval between one
complete cycle and the next
% duty cycle
Time (h)
3.1 Maximum duty cycle curve
Important Notes:
Read these instructions carefully before installing the gate automation system. Keep these
instructions for future reference.
Installation and electrical wiring must conform to current standards.
Switch off power supply before performing any work on the electronic control unit.
Install a 10 A thermal-magnetic differential switch with O.03 A trip threshold up-line from the
electrical system.
FAAC accepts no responsibility for damage or injury resulting from the incorrect use of this

4.1 Preliminary Checks
Proceed as instructed below:
To ensure trouble-free operation, make sure
that the gate (whether existing or yet to be
installed) are within following specifications:
– max. weight of single leaf 800 Kg
– max. length of single gate leaf 4 m (see
table 1)
– strong and rigid leaf frame
– smooth gate movement
– min. clearance between bottom edge of
gate and ground as in fig. 6/a (where ‘s’ =
thickness of guide bracket)
– mechanical travel stops.
If any welding or brazing has to be done on
the gate, do this before installing the
automation system.
a) Existing gate with fixed hinges
– Remove the gate.
– Remove the bottom hinge.
If the gate cannot be removed, place
blocks under its bottom edge to support it.
b) Existing gate with adjustable hinges
– Remove the bottom hinge.
– Slacken off the top hinge.
– Swing the leaf around the axis of the
top hinge (fig. 4).
c) New gate to be installed
– Fit just the top hinge. If possible use an
adjustable hinge.

1. Dig out a hole for the foundation box as
shown in fig. 5.
N.B.: Depending on the nature of the
ground, it may be necessary to cast a
bed of quick-setting concrete at the
bottom of the hole to avoid subsidence
in future.
2. Insert the base box in the hole, fig. 6 a/b.
The centre of the pinion must be
perfectly aligned with the leaf’s axis of
swing.
N.B.: A telescopic rod is available as an
accessory. This can be used to align the
base box and top hinge, fig. 7.

3. Lay down a PVC tube of diameter 40
mm through which the electrical cable
passes. The tube must reach from the
box to the control unit (fig. 8). Install a
second tube as a surface water drain
(fig. 8).
4. Fix the box with concrete.
N.B.: Wait for the concrete to set before
starting this work.
1. Prepare the gate guide bracket as
follows:
– Use a ‘U’ profile of the dimensions
given in fig. 9.
– Ascertain the correct location for the
bushing to suit the position of the gate
with respect to the axis of rotation
(fig. 10 a/b).

– Plate the bushing so that one notch
aligns with the centre-line of the ‘U’
profile (fig. 11).
N.B.: This alignment is essential to the
correct operation of the gate
automation system.
– Carefully weld the bushing to the ‘U’
profile (fig. 12).
– Seal the ‘U’ profile on the post side
with a plate as shown in fig. 13a/b.
2. Grease the pinion.
3. Fit the guide bracket over the pinion
so that the tooth with the punch mark
engages in the bushing notch aligned
along the centre-line of the bracket
(fig. 14).
4. Fit the gate into the guide bracket
and fix the top hinge in place.
Important: do NOT weld the gate to
the guide bracket or to the bushing.

1. Prepare the operator for installation as
follows:
– Remove the plastic cover from the
rack ram (fig. 15).
– Fit the release device (see section 7
page 12).
2. Remove the cover plate from the
foundation box (fig. 16).
3. Manually fit the gate at its half
opening position (angle a, fig. 17).
Caution! Failure to fit the gate at the
right angle will prevent the gate from
opening or closing fully on
completion of the installation.
To determine the precise angle a,
measure the length of line L (fig. 17)
and position the gate at the mid-point
of the line.
4. Fit the operator inside the box and
engage the rack ram with the pinion in
the box (fig. 18).
5. Fix the operator in place with the four
M8 bolts provided (fig. 18). If possible,
use a torque wrench to tighten the
bolts to 2.6 Kgm.
6. Release the operator (see section 7)
and manually open the leaf to check
that the mechanism operates
smoothly.
7. Connect up the cables to the
electronic control unit (see relevant
instructions).

5. Start-up
5.1 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).
Fig. 19
5.2 Adjustment of the internal travel stop screws (model 760 CR only)
Fig. 20a

11
Fig. 20b
Fig. 21
N.B.: Operators are delivered with the travel
stop screws screwed fully in, which
correspond to the maximum leaf opening
angle.
Proceed as follows to set the internal travel
stop adjusting screws.
1. Release the operator (see section 7,
page 12).
2. Manually move the leaf to the closed
position limit stop.
3. Slacken off the lock nut from the closed
travel stop adjusting screw (fig. 20/a).
4. Slacken off the closed travel stop
adjusting screw (fig. 21) until the leaf starts
moving.
5. Screw in the closed travel stop adjusting
screw again by two turns.
6. Tighten the lock nut.
7. Manually move the leaf to the opened
position limit stop.
8. Slacken off the lock nut from the open
travel stop adjusting screw (fig. 20/a).
9. Slacken off the open travel stop adjusting
screw (fig. 21) until the leaf starts moving.
10. Screw in the open travel stop adjusting
screw again by two turns and tighten the
lock nut.
N.B.: Make sure that the leaf always strikes the
mechanical limit stops on the ground.
11. Re-lock the operator (see section 7,
page 12).
If you wish deceleration to start at a lead
angle of less than 10°, screw in the
corresponding travel stop adjusting screw a
couple of turns.
The deceleration ramp can be adjusted on
both opening and closing by turning the
relevant adjusting screws as shown in fig. 22.
Turn the screws anti-clockwise to reduce the
intensity of the deceleration.
5.3 Adjustment of deceleration ramp (model 760 CR only)
Fig. 22

12
Fig. 23
Turn the screws clockwise to increase the
intensity of the deceleration.
Caution! Reduce deceleration action to a
low setting if the system normally has to work
in ambient temperatures above 20 °C. This
avoids deceleration becoming too abrupt
when the temperature drops.
If the total angle of opening of the leaf is less
than 90°, the 760 operators model CR can
be set up so that deceleration is only active
on the closing cycle.
To ensure trouble-free operation, before you
fix the operator inside the foundation box,
move the leaf manually to a distance D from
its fully closed position:
D = L x 0.76 (fig. 23)
where L = leaf length.
See section 5.2 for details on how to set the
internal closed position travel stop adjusting
screws.
Adjustment of the internal open position
travel stop has no effect.
If the gate ever has to be operated manually
as a result of a power failure or malfunction,
release the gate with the key release device.
The release device, without the lock, is
supplied with the operator’s installation kit.
The key lock is available as an accessory in
two versions, with standard or numbered key.
See fig. 24 to fit the key lock to the release
device

The release device must be fixed to the
operator as shown in fig. 25, to ensure the
gate can be released from the inside and
outside.
Proceed as follows to operate the leaf
manually (fig. 26).
– Open the release device access door.
–Insert the release key in the lock.
–Turn the key at least one full turn towards
the gate post.
To re-lock the operator, turn the key in the
opposite direction as far as it will go.
N.B.: The key can only be removed when in
vertical position.
Checking the oil level
The oil level must be kept just below the filler
plug hole (fig. 27).
For low-to-medium duty cycles, you need
only change the level once every 4 years.
With heavy duty cycles, change every two
years.
Top up only with FAAC XD 220 oil.
Bleeding
N.B.: 760 operators have all the air removed
from their hydraulic systems before delivery.
No bleeding is therefore required on initial
installation.
Bleeding is only necessary if work has been
done on the hydraulic system.
Air in the hydraulic system causes irregular
movement of the leaf and noisy operation.
Fig. 25
Fig. 27
Fig. 26

Proceed as follows to bleed air from the
system.
1. Give an opening signal to the gate.
2. While the gate is opening, remove the
access cover and slacken off the opening
bleed screw (ref. C, fig. 20 a/b) as shown in
fig. 28.
3. Wait until only clear, bubble-free oil flows
out.
4. Tighten the bleed screw again before the
operator reaches the end of the opening
cycle.
5. Give a closing signal to the gate.
6. While the gate is closing, remove the
access cover and slacken off the closing
bleed screw (ref. D, fig. 20 a/b) as shown in
fig. 28.
7. Wait until only clear, bubble-free oil flows
out.
8. Tighten the bleed screw again before the
operator reaches the end of the closing
cycle.
Repeat the above operations a few times
on both bleed screws.
9. Top up the oil level to just below the filler
hole (fig. 27). Use only FAAC XD 220 oil.
