• Flat, level support surface.

• Stability and absence of vibrations.

• Absence of aggressive dusts and vapor.

• Absence of drafts.

• Ensure the platform is level or that the load cells are evenly supported.

• Moderate temperature and humidity: 59°F - 86°F (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. Read the electrical precautions listed in the section “Electrical Precautions”.

• Ensure the system is correctly grounded, see the relevant section “System Grounding”.

• 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.

System Grounding

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 14 AWG (2.5 mm

2

). The

transmitter must be powered by a dedicated power supply with earth reference. Do not connect EARTH and GND terminals together!

SCT-1SX Correct earth connection

GND Vdc

+-

SCT-1SX

Incorrect earth connection

1 2

GND Vdc

+-

LOAD CELLS AND JUNCTION BOX

The connection must be made by connecting the ground cables to the ground bar (cables that must have a cross-section of at least 6 AWG/16 mm

2

); ﬁnally, connect the earth bar to the earth post with a cable having a cross-section of at least 1-1/0 AWG (50 mm2).

EXAMPLES:

• If more 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

6 AWG (16 mm2)

.

• If the load cell is 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 33 ft (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 6 AWG (16 mm

2

).

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 6 AWG (16

2

mm

) (refer to the grounding 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.

i

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 .

• 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 1-1/0 AWG (50 mm2);

- the earth post must be placed at a distance of at least 33 ft (10 m) from the structure.

• If the load receiver is more than 33 ft (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 must be properly connected to the terminal block of the transmitter (see page 17).

The transmitter has one channel for 6-wire connection to load cells (using the REFERENCE). 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 32 ft (10 meters), or in high-resolution applications.

Anti-peak Filter

The transmitter has an additional ﬁlter for the elimination of sudden weight peaks (e.g. shocks or falling material). The following parameters, opportunely conﬁgured, allow you to eliminate the peak by blocking the weight for its entire duration. The weight is blocked if it remains within the number of divisions set in PK.LK.DV for the time set in PK.LK.TM and is subsequently unblocked if the weight deviates from the blocking value for a number of divisions greater than PK.DIV (or PK.BN.DV) or if the time set in

Saving a Weighing Operation in the Alibi Memory

A weighing operation is stored after receiving the PID serial command (see “Serial commands” page 44) or after pressing the 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, 1.000lb, 1.000lb,00126-131072

The next one will be:

PIDST,1, 1.000lb, 1.000lb,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. In addition, if the transmitter is restricted, the weight must exceed 20 divisions.

Displayed if you try to calibrate a point without ﬁrst conﬁrming the number of calibration points (n tp).

Calibration error: unstable weight during point acquisition.

Calibration error: during the acquisition of a calibration point a NULL value was read from the converter.

Error that occurs if the capacity of channel X is not set, or there is an error in the calibration parameters of channel X, where X indicates the number of the channel to which the error refers.

Calibration error: a sample weight that is too low was used; it is recommended to use a weight of at least half the scale’s capacity.

Calibration error: The acquired calibration point (tp 1 / tp 2 / tp 3) is equal to the zero point (tp0).

Scale to be calibrated (we recommend resetting the transmitter to the factory default “defau” settings before proceeding).

Negative internal points were calculated during calibration:

• the calibration point is below the zero point;

• the signal is negative (check the connections).

Internal points below the minimum value were calculated during calibration:

• the calibration point is equal to the zero point;

• too high a capacity has been set with respect to the division.

Hardware error: software not compatible with the installed hardware.
