3.2. INSTALLING THE OPERATOR

1)Dig out a hole for the base plate as

shown in fig. 3.
In order to ensure the correct
engaging of the pinion and rack, the
base plate must be placed in the
position shown in fig. 4a (right closing)
or 4b (left closing).

N.B. it is advisable to place the base plate on a concrete foundation at about 50 mm
from the ground (fig. 5).

2) Lay the flexible pipes for connection cables between operator, accessories, and

power supply. The flexible pipes must protrude by approximately 3 cm from the
opening on the plate (fig 3).

3) Cement in the plate, ensuring that it is perfectly level.
4) Wait for the concrete to set in the hole.
5) Lay the cables for connection with accessories and power supply. To facilitate

the electrical wiring on the electronic unit, about 30 cm of cable should come
out of the opening on the base plate.

6) Fasten the operator to the base plate by means of the screws and washers

supplied, as shown in fig. 6.
The positioning of the operator is shown in fig. 5.
Pass the electrical cables through the relevant
opening (fig. 1 - ref. 5) on the base of the operator.

7)Pass the electrical connection cables through the

relevant opening on the base of the electronic
control unit support (fig. 1 - ref. 3), using the cable
clamp supplied.

8) Connect up the cables to the electronic control

unit.
Important: connect up the earth cable of the
system to the position shown in fig. 1 - ref. 12.

3.3. ASSEMBLING THE RACK

1) Fit the rack by means of the screws TE 8 x 25 and the spacers provided, as shown

in figure 7.
To avoid welding to the gate, galvanized passing spacers with screws TE 8 x 50 are
provided.
N.B. it is advisable to tighten the rack fixing screws at the top of the slot. This allows
the rack to be raised if, with time, the gate tends to sink.

2) Release the operator (see paragraph 3.5).
3) Slide the gate leaf open, by hand.
4) Place the first section of the rack on the pinion,

aligning the latter with the first spacer (fig. 8).

5) Fix the rack section to the leaf by means of a

clamp (fig. 8).

6) Slide the gate leaf by hand towards its closed

position, until it is in line with the third spacer on
the rack, and spot weld the spacer in position.

7) Completely weld the three spacers to the gate.

To fasten the other rack sections needed to reach the position of complete
closing, proceed as follows:

8) Line up another rack section to the last one fixed to the gate. Use a section of rack

of about 150 mm and ensure that the teeth are correctly spaced (fig. 9).

9) Slide the gate by hand towards its closed position until the third spacer of the

section to be fastened is aligned with the pinion (fig. 9).
N.B. ensure that all the rack sections are correctly centered on the pinion teeth.
If not, adjust the position of the operator.

10)Weld the three spacers of the section (fig. 9).

Caution:
a)

do not weld the rack sections to the spacers or to each other;

b)

do not use grease or other lubricants on the pinion and rack.

11)To obtain a correct slack between the pinion and rack, lower the operator by 1.5

mm, by means of the support nuts of the base plate (fig. 10).
When this adjustment has been completed, tighten the screws that fasten the
operator.
Caution: If the gate is new, check the slack (fig. 11) after a few months.

12)Manually check whether the gate can open completely and the movement of

the leaf is smooth and even, over its entire travel.
