• Read the instructions carefully before installing the gate automation system. Keep these instructions for future reference.

• Installation, electrical wiring and adjustments must be carried out in compliance with current safety standards.

• FAAC cannot be held responsible for failure to observe technical standards in the construction of gates, or for any deformation of the gates

which may occur during use.

•Before installing the gate automation system, make all necessary structural modifications to ensure safety clearances, and for the protection

and/or isolation of all cutting, entrapment, and crushing areas.

•This equipment should be defined only to the use for which it has been expressly conceived (all equipment), any other use should be

considered improper and therefore dangerous. The manufacturer cannot be held responsible for eventual damage caused by improper,

incorrect and unreasonable use.

• Do not use this device in areas subject to explosion: the presence of flammable gases or fumes is a serious hazard.

• Before carrying out any cleaning or maintenance operations, unplug the equipment from the electrical supply network either by removing

the plug or by turning off the system’s main switch.

•An isolation switch should be provided for the installation according to by current safety regulations with an opening distance of 3 mm or

more on the part of the contacts. Alternatively, use a 6A thermo-magnetic breaker with multi-pole switching.

• Ensure that there is a differential switch up-line of the electrical system, with a trip threshold of 0.03A.

• Check that the earthing plant is in perfect condition and connect it to the gate frame. Also earth the yellow/green wire of the operator.

•The end-user must avoid any attempt to repair or adjust the automation system; these operations must be carried out exclusively by

qualified personnel.

•Use only FAAC original spare parts for maintenance operations.

•Do not carry out any modifications to automation components.

•Packaging material (plastic, polystyrene etc.) is a potential hazard and must be kept out of reach of children

•The installer must supply all information regarding manual operation of the system in the event of an emergency and provide the end-user

with the leaflet attached to the product.

•The operator is fitted with an anti-crush safety system, this is a torque control device which guarantees ultimate safety and reliability if properly

adjusted

•In any event, FAAC always recommends the installation of other safety devices, taking into consideration current safety standards, installation

site, system operation logics, dimensions and weight of the gate.

• The safety devices (e.g photocells, safety edges, etc.) will protect the crushing and entrapment areas and general potential hazard areas of

the automation.

•Each installation must be fitted with at least one flashing light (e,g, FAAC LAMP, MINILAMP etc,) as well as a warning plate suitably fixed to the

gate.

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

gate automation system.

4.2 Installation of leaf supporting foundation box (fig.3)

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).

Fig. 10b

4.3 Setting up the gate

– 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).
