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 dierent 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
beinserted 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.

Grounding 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 14 AWG (2.5 mm2). The
transmitter must be powered by a dedicated power supply with ground. Do not connect EARTH and GND terminals together!
SCT-4X Correct earth connection

GND Vdc
+-
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 6 AWG
(16 mm2); 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 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
6 AWG (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
theearthing 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 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 6 AWG (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 eects, the earth reference
ofthe 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 (10 m) from the structure.
• If the load receiver is more than 33 (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 page 17).
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 33 ft (10 meters), or in high-resolution
applications.
i
The SCT-4X has a DIP switch (EXC-SEN) located under the cover for Cell 1 and 2 connections. Set the DIP switch to correspond
with the type of load cells connected to the transmitter:
• ON for a 4-wire connection
• OFF for a 6-wire connection

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 P K . L K . D V for the time set in P K . L K . T M and is subsequently
unblocked if the weight deviates from the blocking value for a number of divisions greater than P K . D I V (o P K . b n . d v ) or if the time set in
P K . T I M E has elapsed.

Saving a Weighing Operation in Alibi Memory
A weighing operation is stored after receiving the PID serial command (see “Serial commands” page 54) 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, 1.000lb, 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 (see “Reactivating printing” on page 50).
In addition, if the transmitter is restricted, 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.

Reading 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 “ r e w . i d” (from 0 to 255) and the ID number “ i d” (from 0 to 131072).
The weighing data are shown. Use the and keys to scroll through the following information:
• “ C h . X”, where X indicates the scale number.
• “ U m YY”, where YY indicates the unit of measurement ( k G, G, t or l b).
• “ G r o s s”, followed by the gross weight.
• “ T a r e / t a r e p t”, 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 54.
FROM PLC

Serial Communication Configuration
The transmitter has 3 serial ports (COM1 / 232, COM2 / 485, USB) that can be used indiscriminately to communicate:
In bidirectional mode with the PC / PLC (“PC” port);
In one-directional mode with the PC, thermal printer, repeater (“PRN” port);
The USB port always allows quick connection to the PC to change / save / restore the transmitter settings at any time.
It is necessary to choose which port to use as PC and, consequently, which one to use as PRN.

Serial Commands
By selecting the PC port on demand mode ( o n d e), 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<CR LF> Command sent when sending a correct command. This response does not imply that the command is executed.
ERR01<CR LF> Command sent correctly but followed by letters entered unintentionally (e.g. READF, TARES).
ERR02<CR LF> Incorrect command data.
ERR03<CR LF> Command sent not allowed (transmitter busy, or not used in the selected operating mode).
ERR04<CR LF> Command sent non-existent.
i
If the 485 protocol has been selected, you must precede the command with the transmitter address (e.g. 01READ).

Unbalancing
The instrument has an active unbalance function as standard that signals if the load is unevenly distributed, compared to the stored
condition.
Imbalance occurs when the load distribution percentage value on a cell deviates by at least 10% for more than 3 seconds.
It is possible to change these value with the following parameters:

Displayed if you try to calibrate a point without first confirming the number of calibration points ( n t p).
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.
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 ( t p 1 / t p 2 / t p 3 ) is equal to the zero point ( t p 0).
Scale to be calibrated (we recommend resetting the transmitter to the factory default “ d e f a u” settings before
proceeding).
Scale to be calibrated (we recommend resetting the transmitter to the factory default “ d e f a u” 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.
