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.
8
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 different 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 load cells, junction box, if any, and weighing structure must be earthed.
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 effects, 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 mm2 instead of 16 mm2 and 100 mm2 instead 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 SENSE), while for the remaining channels (CELL2,
CELL3, CELL4) only 4-wire connection is allowed.
The SENSE 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.

Saving a weighing operation in the alibi memory

A weighing operation is stored after receiving the PID serial command (see “Serial commands” page 51) or after pressing the key.
The transmitter transmits on the PC port the gross weight, the tare and an ID code that uniquely identifies the weighing. The ID has the
following format:
• rewrite number: 5-digit number (from 00000 to 00255) indicating the number of complete rewrites;
• weighing number: 6-digit number (from 000000 to 131072) indicating the weighing number in the current rewrite.
Each time it is saved, the weighing number is increased by 1; when it reaches the value 131072, it starts again from 000000 and the
rewrite number is increased by 1.
Example
If the weighing that has been saved is as follows:
PIDST,1, 1.000kg, 1.000kg,00126-131072
The next one will be:
PIDST,1, 1.000kg, 1.000kg,00127-000000
A weighing operation can only be saved if the weight ≥ 0, stable and valid (not underloaded or overloaded).
To store the weighing operation by key, the function must be active (see “Reactivating printing” on page 47).
In addition, if the transmitter is approved, the weight must exceed 20 divisions.
If these conditions are not met:

• the response to the PID command will have “NO” instead of the ID (PIDST,1, 1.000kg, 1.000kg,NO);
• there is no transmission when the key is pressed.
LEGEND:

USER_MAN_ENG_DGTQ
Reading the alibi memory
FROM THE TRANSMITTER (MANUAL)
By pressing the key you can read a saved weight:

you will be asked to enter the rewrite number “rew.id” (from 0 to 255) and the ID number “id” (from 0 to 131072).
The weighing data are shown. Use the and keys to scroll through the following information:
• “Ch. X”, where X indicates the scale number.
• “Um YY”, where YY indicates the unit of measurement (kG, G, t or lb).
• “Gross”, followed by the gross weight.
• “Tare / tarept”, followed by the tare value.
Press the key to return to weighing.
The weighing of an ID can only be verified if:

• it has a rewrite number equal to the current alibi memory number and a weighing number ≤ the last value received with the PID
command;
• it has a rewrite number ≥ 0, but 1 less than the current alibi memory value, and a weighing number greater than the last value received
with the PID command.
FROM PC
To read a weighing operation from a PC, see the serial command “READING A WEIGHING OPERATION IN THE ALIBI MEMORY” on
page 53.
FROM PLC
To read a weighing operation from a PLC, refer to the Modbus and Fieldbus protocol manuals.
i
If the alibi memory is empty, when the key is pressed the display shows “empty” for one second and returns to weighing mode.
If an invalid ID is entered, the display shows “No id” and returns to weighing mode.

Serial commands
By selecting the PC port on demand mode (onde), you can communicate with the transmitter via serial commands.
For each command received, the transmitter emits a string containing the response (refer to the command description) or one of the
following signals:
OK<CRLF> Command sent when sending a correct command. This response does not imply that the command is executed.
ERR01<CRLF> Command sent correctly but followed by letters entered unintentionally (e.g. READF, TARES).
ERR02<CRLF> Incorrect command data.
ERR03<CRLF> Command sent not allowed (transmitter busy, or not used in the selected operating mode).
ERR04<CRLF> Command sent non-existent.
