2.6 INSTALLING THE GATE
Fig.2-23-24/a-24/b-25-26/a-26/b-27
1) Unlock the system (see paragraph 6).
2) Turn the splined bushing, inserted on the pinion, in closing
direction until it stops.
3) To avoid the piston reaching the internal mechanical stop,
turn the bushing 5 degrees in the direction of opening.
4) Make the gate guide bracket:
take a U-section sized as shown in fig.23;
position the section on the splined bushing in the “leaf
closed” position;
determine the correct position of the bushing by referring
to the position of the leaf with respect to the rotation axis
(fig.24/a-b);
weld the bushing to the section using two welding points;
check that the system timing is correct by simulating
complete opening;
carefully weld the bushing to the section (fig.25);
close the U-section, on the post side, using a plate as
shown in fig.26/a-b.
5) Lubricate the jack pinion using grease.
6) Insert the guide bracket on the pinion in the previous “leaf
closed” position.
7) Place the gate in the bracket and hinge the top part.
The gate must rest on the guide bracket. To
increase the jack height, turn the levelling set
screws clockwise (fig.2-ref.7).
In order to not compromise correct operation of
the automated system, never weld the gate leaf
to the guide bracket or directly to the splined
bushing.
8) Manually check that the gate freely opens completely,
stopping on the external stops and that the movement
of the leaf is smooth and without friction.
9) Correctly position the jack protection box as shown in
fig.27.
10) Wall in the box using cement. To avoid possible
deformation, also fix the box cover.
3 OPERATION
3.1. CHECKING THE SENSE OF ROTATION
1) Cut off power to the electronic control unit.
2) Manually place the gate in the centre of the opening
angle.
3) Lock the system again (see paragraph 6).
4) Restore power.
5) Send an OPEN pulse and ensure that the gate opens.
If the first OPEN pulse commands closing, invert the phases of
the electrical motor on the unit terminal board (brown and black
wires).
3.2 SETTING OPERATION TIME
Opening/Closing time is determined by programming the
electronic control unit (see corresponding instructions).
To obtain maximum efficiency of the hydraulic locking system,
it is necessary to program an opening/closing time that allows
maintaining the electric motor powered for a few seconds after
the leaf has reached the mechanical stop.
3.3. SETTING THE ANTI-CRUSHING SYSTEM
Fig.28
With inward opening, the 750 automated system features an
anti-crushing system that guarantees stopping the movement

in the presence of an obstacle.
We recommend calibrating this torque regulator in compliance
with the laws in force.
To do this accurately, use a linear torque wrench as a strength
measuring tool.
Setting of the anti-crushing system tripping threshold is done using
the by-pass screws as shown in fig. 28.
The red screw adjusts the closing torque of the leaf.
The green screw adjusts the opening torque of the leaf.
To increase torque, turn the screws clockwise.
To reduce torque, turn the screws anticlockwise.
4 TESTING THE AUTOMATED SYSTEM
5 MANUAL OPERATION
Fig.29
Should manually operating the gate be required due to power
cut-offs or automated system inefficiency, use the release lever
as shown in fig.29.
To lock the system again, place the lever in its original position
and ensure that it reaches the stop.
6 MAINTENANCE
Fig.20
During maintenance, periodically check the oil level using the
references on the oil filler cap rod (fig.20).
Check the gate structure every 6 months.
When required, top up oil using only FAAC HP OIL.
It is also necessary to periodically check both the correct setting
of the by-pass screws and the efficiency of the release system
(see the corresponding paragraphs).
Also periodically check the gate structure and in particular ensure
that the top hinge is in perfect working condition.
The system’s safety devices must be checked every 6 months.
