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.

Earthing of the system
For correct earthing and optimal system operation, the transmitter, load cells, junction box, if any, and weighing structure must be
earthed.
TRANSMITTER
The earth connection must be made via the appropriate terminal. The cable cross-section must be less than 2.5 mm2.
LOAD CELLS AND JUNCTION BOX
The connection must be made by connecting the earth cables to the earth bar (cables that must have a cross-section of at least 16 mm2);
finally, connect the earth bar to the earth post with a cable having a cross-section of at least 50 mm2.
EXAMPLES:
• If the load cells are connected to the transmitter through a junction box, the cable shield from the transmitter and the cell cable shields
must be connected to the earth socket of the junction box (refer to the junction box manual) and the junction box must be earthed using
a copper cable with a cross-section of not less than 16 mm2.
• If the load cells are connected directly to the transmitter (without using the junction box), the cell cable shields must be connected to
theearthing point (or earth bar).
• If the weighing system involves large and/or outdoor structures (weighbridges, silos, etc.) and the distance between the junction box
andthe weight transmitter is greater than 10 m, connect the cell cable shields to the earth socket in the junction box.
WEIGHING STRUCTURE
Earth the weighing structure and/or any unconnected structures (e.g. silos that release material onto the weighing structure) using cables
with a cross-section of not less than 16 mm2.
Also connect the upper part with the lower part of each cell by means of a copper braid with a cross-section not less than 16 mm2(refer
to the earthing examples on page 12 and page 13).
SERIAL CABLES AND CONNECTED INSTRUMENTS
Connect the serial cable shield to the earthing point (or earth bar) inside the panel. To avoid any undesired eects, the earth reference
ofthe connection cable, power supply and transmitter must be at the same potential.
GENERAL NOTES:
• All earth cables must be of suitable length, so as to obtain an overall resistance of the earthing system of less than 1 Ω.
• If the weighing system involves large and/or outdoor structures (weighbridges, silos, etc.):
- the earth connection must be made by connecting the earth cables to an earth bar and the earth bar to the earth post
with a cable having a cross-section of not less than 50 mm2;
- the thickness of the cables must be greater (50 mm2instead of 16 mm2and 100 mm2instead of 50 mm2), because the
voltages at stake are greater (e.g. lightning);
- the earth post must be placed at a distance of at least 10 m from the structure.
• If the load receiver is more than 10 m from the transmitter, we recommend using the SENSE line and load cells equipped
with a (SENSE) compensation circuit.

Load cell installation
After carrying out the instructions for the platform or load receiver, the shielded cable from the cell(s) must be properly connected to the
terminal block(s) of the transmitter (from CELL1 to CELL4; see section “Wiring diagrams”).
The transmitter has one channel (CELL1) for 6-wire connection to load cells (using the REFERENCE), while for the remaining channels
(CELL2, CELL3, CELL4) only 4-wire connection is allowed.
The REFERENCE allows you to compensate for any voltage drop on the section of cable connecting the transmitter to the load receiver.
It is especially useful when the distance between the transmitter and the load receiver is more than 10 metres, or in high-resolution
applications.
