7.2) Mod. CPZ

(Fig.8).

Plastic rack - 22x22mm section - supplied in 3,28ft (1- metre) lengths - max.

capacity 1102,3lb (500kg (

≈

5000N)). This model is to be fixed to the gate

by means of normal or self-threading screws. Also in this case, you are

advised to insert a section of rack the other way round in the joint between

the various pieces, so as to maintain the correct tooth pitch. This type of

rack is quieter and allows height adjustments to be made even after having

been fixed, using the slots provided.

7.3) Mod. CVZ

(Fig.8)

Galvanised iron rack - 1,18x0,47“(30x12mm) section - supplied in 3,28ft (1

- metre) lengths - threaded spacers to be welded - max. capacity 4409,2 lb

(2000kg (

≈

20000N)). Having fixed the spacers in the middle of each of the

slots in the various rack pieces, weld the spacers to the gate. Also in this

case, arrange a section of rack the other way round in the joining points of

the various rack pieces to ensure a correct tooth pitch. The screws which fix

the rack to the spacers allow the rack to be adjusted in height.

7.4) Rack fitting

To fit the rack, proceed as follows:

• Activate the emergency release by rotating the appropriate release knob

(See paragraph “Emergency manoeuvre”).

• Rest the rack end on the control pinion and secure it (by welding or using

screws) in correspondence with the pinion, while sliding the gate along

by hand (fig. 9).

• In the case of incorrect gate alignment (excessive side curving) which

cannot be corrected, place a few shims between the rack and gate in

order to ensure continuous centring of the rack with respect to the pinion

(fig. 10).

DANGER - The welding operation is to be carried out by a competent

person who must be provided with all the personal protection equipment

required by the current safety standards.

8) PINION ADJUSTMENT

Having finished fixing the rack, the rack-pinion play needs to be adjusted to

approximately 0,078”(2mm) (fig.6): this is obtained by slackening the four

M10 nuts under the gearmotor base by approximately 0,078”(2mm), and

then securing the four upper nuts. Make sure that the rack and pinion are

aligned and centred (fig.10).

WARNING - Remember that the rack and pinion life strictly depends

on their correct meshing.

9) ELECTROMECHANICAL LIMITING DEVICES

The operation must be carried out with the emergency release activated and

the mains power supply disconnected. The runners which control the limiting

devices are to be positioned at both ends of the rack.

- Push the gate fully open by hand.

- Position the opening end-of-stroke runner (fig.11) so that it intercepts the

microswitch control lever and makes it trigger. Having identified the correct

position, tighten the runner screws.

- Push the gate fully closed by hand.

- Position the closing end-of-stroke runner (fig.11) so that it intercepts the

microswitch control lever and makes it trigger. Having identified the correct

position, tighten the runner screws.

- The runners must lock the gate before this intercepts the mechanical

backstops placed on the track. The closing end-of-stroke runner adjustment

must be made in such a way as to leave a clearance of approximately

50mm between the gate and the fixed swing leaf, as prescribed by the

current safety standards, otherwise fit an electric edge at least 50mm

thick (fig.12).

10) GATE BACKSTOPS

DANGER - The gate must be provided with mechanical backstops, both

on opening and closing, in order prevent it from coming out of the upper

guide (fig.13); the backstops must be tightly secured to the ground, a

few centimetres beyond the electrical stop point.

11) ELECTRICAL INSTALLATION SETUP

Lay out the electrical installation as shown in fig.14 with reference to the CEI

64-8 and IEC364 provisions complying with the HD384 and other national

standards in force for electrical installation.

WARNING! For connection to the mains, use a multipolar cable having

a minimum cross section of 3x16 AWG and complying with the current

standards. (For example, if the cable is not protected, it must be at least

equal to H07 RN-F, whereas if it is protected it must be at least equal

to H07 VV-F with a 3x16 AWG sq cross section).

Connect the control and safety devices in compliance with the previously

mentioned technical installation standards. The cables (mains and auxiliary)

must be distinctly separated. Fig.14 shows the number of connections and

their cross sections for a length of approximately 328,08 ft(100 metres); for

greater lengths, calculate the cross section for the true automation load.

The main automation components are (fig.14):

Type-approved adequately rated omnipolar circuit-breaker with

at least 0,14”(3,5 mm) contact opening, provided with protection

against overloads and short circuits, suitable for cutting out automa-

tion from the mains. If not already install ed, place a type-approved

omnipolar circuit-breaker with a 0.03A threshold just before the

automation system.

ANTENNA INSTALLATION
Use an antenna tuned to 433MHz.
For Antenna-Receiver connection, use RG8 coaxial cable.

The presence of metallic masses next to the antenna can interfere with radio
reception. In case of insufficient transmitter range, move the antenna to a
more suitable position.

12) TERMINAL CONNECTIONS

After adequate electric cables have been made to pass through the raceways

and the various automation components fixed to the chosen points, these

must be connected according to the instructions and diagrams shown in the

relevant instruction manuals. Connect the phase, neutral and earth (com-

pulsory) cables. The mains cable is to be secured in the appropriate cable

clamp (fig.15- ref. P1), the accessory cables in their cable clamp (fig.15- ref.

P2), and the protection (earth) wire, having a yellow/green insulating sheath,

must be held in its appropriate wire clamp (fig.15 - ref. S).

The automation device is to be set at work after all the safety devices have

been connected and checked. See the terminal diagram in fig.16.
