Dear Customer,

Thank you for purchasing a DINI ARGEO product.

This manual contains all the instructions for a correct installation and commissioning of the DGT4X 4-channel digital weight transmitter.

While thanking you for purchasing this product, we would like to draw your attention to some aspects of this manual.

This booklet provides useful information for the correct operation and maintenance of the scale to which it refers;

it is therefore essential to pay the greatest attention to all those paragraphs that illustrate the simplest and safest way to operate.

It is recommended that you carefully follow the instructions for programming the weight transmitter; performing actions not indicated in

this manual could compromise the proper functioning of the scale.

The utmost care has been taken in compiling this manual, but reports of any inaccuracies are always welcome.

The transmitter is covered by warranty and MUST NOT BE TAMPERED WITH BY THE USER under any circumstances.

Any attempt at repair or modiﬁcation may expose the user to the danger of electric shock and voids any warranty conditions, relieving

the Manufacturer from all liability.

Any problem with the product must be reported to the manufacturer or to the retailer where it was purchased.

In any case, always TURN OFF THE POWER SUPPLY before any installation or repair operation.

Transmitter installation

Installation requirements

Observe the following conditions for correct installation of the transmitter and of the load receiver:

• Flat, level support surface.

• Stability and absence of vibrations.

• Absence of aggressive dusts and vapours.

• Absence of draughts.

• Make sure that the platform is levelled or that the load cells are evenly supported.

• Moderate temperature and humidity (15°C - 30°C and 40% - 70%).

• Do not install in an environment where there is a risk of explosion.

• All transmitter connections must be made in accordance with applicable regulations in the area and environment of installation.

Observe the electrical precautions listed in the section “Electrical precautions”.

• Ensure that it is correctly earthed, see the relevant section “Earthing of the system”.

• Do not perform welding when the load cells have already been installed.

• If necessary, use watertight sheaths and ﬁttings to protect the load cell cables.

• Any junction boxes must be watertight.

• Anything not expressly described in this manual constitutes improper use of the equipment.

Electrical precautions

• Use a regulated mains supply within ± 10% of the rated voltage.

• The electrical protections (fuses, etc.) are the responsibility of the installer.

• Observe the recommended minimum distances between cables of dierent categories (see table on page 10).

• The following cables must comply with the maximum permissible lengths (see table on page 10), they must be shielded and must

beinserted alone in metal conduits or pipes:

- the load cell extension cables;

- the signal ampliﬁer cables;

- the cables for connecting the serial ports;

- the analog output cables.

• The cell or ampliﬁer cables must have an independent input in the electrical panel. They must be connected (if possible) directly to

the terminal block of the transmitter without passing through the conduit with other cables.

• Fit “RC” ﬁlters:

- on the contactor coils;

- on the solenoid valve coils;

- on all devices that produce electrical interference.

• If condensation can occur inside the weight transmitter, it is advisable to keep the equipment powered at all times.

• Connections to load cells and any external device must be as short as possible.

• The cable ends (connectors, leads, terminals, etc.) must be installed correctly; the cable shielding must be kept intact until close to

the connection point.

• If the transmitter is placed inside an electrical panel, a shielded cable must also be used for the power supply.
