1.1.3 Equipment Recommendations
Failure to follow the installation recommendations will be
considered a misuse of the equipment.
To Avoid Equipment Damage
• Keep away from heat sources and direct sunlight.
• Protect the instrument from rain.
• Do not wash, dip in water or spill liquid on the instrument.
• Do not use solvents to clean the instrument.
• Do not install in areas subject to explosion hazard.
1.1.4 Correct Installation of Weighing Instruments
• The terminals indicated on the instrument’s wiring diagram to be connected to
ground must have the same potential as the scale structure (ground). If you are
unable to ensure this condition, connect a ground wire between the instrument
and the scale structure.
• The load cell cable must be run separately to the instrument input and not share a
conduit with other cables. A shielded connection must be continuous without a
splice.
• Use “RC” filters (quench-arcs) on the instrument-driven solenoid valve and
remote control switch coils.
• Avoid electrical noise in the instrument panel; if inevitable, use special filters or
sheet metal partitions to isolate.
• The panel installer must provide electrical protection for the instruments (fuses,
door lock switch, etc.).
• It is advisable to leave equipment always switched on to prevent the formation of
condensation.
• Maximum cable lengths:
- RS-485: 1000 meters with AWG24, shielded and twisted cables
- Analog current output: up to 500 meters with 0.5 mm2cable
- Analog current output: up to 300 meters with 0.5 mm2cable
1.1.5 Correct Installation of the Load Cells
Installing Load Cells:
The load cells must be placed on rigid, stable structures within .5% of plumb and
level. It is important to use mounting modules for load cells to compensate for
misalignment of the support surfaces.
Protection Of The Load Cell Cable:
Use waterproof sheaths and joints in order to protect the cables of the load cells.
Mechanical Restraints (pipes, etc.):
When pipes are present, we recommend the use of hoses, flexible couplings and
rubber skirted joints. In case of rigid conduit and pipes, place the pipe support or
anchor bracket as far as possible from the weighed structure (at a distance at least 40
times the diameter of the pipe).
Important

Introduction 3
Connecting Several Cells in Parallel:
Connect several load cells in parallel by using, if necessary, a watertight junction box
with a terminal box. The load cell connection extension cables must be shielded,
placed individually into their piping or conduit, and laid as far as possible from the
power cables (in case of 4-wire connections, use cables with 4 x 1 sq.mm minimum
cross-section).
Welding:
Avoid welding with the load cells already installed. If this cannot be avoided, place
the welder ground clamp close to the required welding point to prevent sending
current through the load cell body.
Windy Conditions - Shocks - Vibrations:
The use of weigh modules is strongly recommended for all load cells to compensate
for misalignment of the support surfaces. The system designer must ensure that the
scale is protected against lateral shifting and tipping relating to shocks and vibration,
windy conditions, seismic conditions and stability of the support structure.
Grounding The Weighed Structure:
By means of a 10 AWG solid or braided wire or braided grounding strap, connect the
load cell upper support plate with the lower support plate, then connect all the lower
plates to a single earth ground. Once installed, electrostatic charges are discharged to
the ground without going through or damaging the load cells. Failure to implement a
proper grounding system might not affect the operation of the weighing system; this,
however, does not rule out the possibility that the load cells and connected instrument
may become damaged by ESD. It is forbidden to ensure grounding system continuity
by using metal parts contained in the weighed structure(see Figure 1-1).

1.1.6 Load Cell Testing
Load Cell Resistance Measurement (Use a Digital Multimeter):
• Disconnect the load cells from the instrument and check that there is no moisture
in the load cell junction box caused by condensation or water infiltration. If so,
drain the system or replace it if necessary.
• The value between the positive signal wire and the negative signal wire must be
equal or similar to the one indicated in the load cell data sheet (output resistance).
• The value between the positive excitation wire and the negative excitation wire
must be equal or similar to the one indicated in the load cell data sheet (input
resistance).
• The insulation value between the shield and any other load cell wire, and
between any other load cell wire and the body of the load cell, must be higher
than 20 Mohm (mega ohms).
Load Cell Voltage Measurement (Use a Digital Multimeter):
• Remove weight of scale from load cell to be tested.
• Make sure that the excitation wires of the load cell connected to the instrument is
5 Vdc +/- 3%.
• Measure the millivolt signal between the positive and the negative signal wires
by directly connecting them to the multi-meter, and make sure it reads between 0
and 0.5 mV (thousandths of a volt).
• Apply load to the load cell and make sure that there is a signal increment.
If one of the above conditions is not met, please contact the
technical assistance service.

1.5 Instrument Commissioning
1. Power on the transmitter and wait five minutes until all the components have
reached a stable temperature.
2. Check that the display shows the mV value of the load cells and that when
loading the load cells there is an increase in weight.
3. If there is not, check and verify the connections and correct positioning of
the load cells.
4. Set the three-way selector switch to ZERO, the red LED will light.
If the display reads BLOCK, zero setting is not enabled.
5. The display shows the load cell reading in mV and the flashing zero value of
the selected analog output (0 V, 0 mA or 4 mA); adjust the analog output
value by turning the control knob.
6. Hold the control knob down until the display reads ZERO.
7. Release the control knob and set the selector switch back to NORMAL.
Zero setting can also be obtained by referring to the values read by
devices connected to the instrument, such as the PC or PLC.
Note
Note

Calibration 9
2.0 Calibration
Before carrying out the instrument real calibration, the type of analog output must be
selected and the tare weight zero setting must be performed.
2.1 Real Calibration (With Sample Weights)
1. Load a sample weight (at least 50% of the full scale value) onto the weighing
system.
2. Set the three-way selector switch to FS CAL. The yellow LED will light.
If the display reads BLOCK, zero setting is not enabled.
3. The display shows the load cell reading in mV and the corresponding
flashing value of the analog output. Adjust the analog output value by
turning the control knob.
4. Hold the control knob down until the display reads FS CAL.
5. Release the knob control and set the selector switch back to NORMAL.
Calibration can also be obtained by referring to the values read by
devices connected to the instrument, such as the PC or PLC.
Example:
The weighing system uses four 1000 kg cells, the 4-20mA analog output has been
selected and you wish to have 20 mA at 2000 kg. Check that the system is not
loaded; perform the tare weight zero setting and load a sample weight of 1000 kg
onto the system (equal to 50% of the required full scale value); move the selector
switch to FS CAL and set the analog output value to 12 mA by working the knob
control (range: 20 – 4 = 16 mA; ½ of the range: 16 / 2 = 8 mA; ½ of full scale: 8 + 4 =
12 mA); hold down the knob control until the display reads FS CAL; release the
knob control and set the selector switch back to NORMAL.
With this type of calibration it is possible to set the analog output value corresponding
to a given value in mV read by the cell.
Note
Note

10 SCT-30 Weight Transmitter Manual
2.2 Theoretical Calibration
Theoretical calibration may be carried out with or without load cells
connected to the instrument. The analog output is zero (4 mA for the
4-20 mA output case) when the value read by the cell is 0 mV.
1. Hold down the control knob and set the selector switch to FS CAL within
four seconds. The yellow LED will light.
2. Release the control knob.
3. 5.000mV will flash on the first line of the display. Adjust the value by
turning the control knob.
4. Hold down the control knob for at least three seconds.
5. Upon releasing the control knob, line two on the display will start flashing.
6. Adjust the analog output value by turning the control knob.
7. Hold down the control knob for at least three seconds.
8. Upon releasing the control knob, the first display line begins to flash again.
Confirm the settings by adjusting the selector switch to NORMAL or change
the values again by repeating the above.
Ensure that the weighing system is not loaded and perform the tare
weight zero setting.
Example:
The weighing system uses four 1000 kg cells with 2 mV/V sensitivity, the 4-20mA
analog output has been selected and you wish to have 20 mA at 2000 kg.
Considering that the instrument provides 5 Vdc supply for the load cells, the cell
full scale value is equal to 2 mV/V x 5 V = 10 mV. Additionally, 2000 kg is equal to
50% of the system full scale (4 x 1000 kg = 4000 kg), therefore, the values to enter
are 50% of 10 mV = 5 mV and 20 mA.
2.3 Digital Filtering
The instrument has a digital filter to reduce the effects of weight oscillation. Set the
DIP switch indicated by FILTER.
For an increased effect (weight more stable) increase the value of the
response time.

RS-485 Serial Connection 11
3.0 RS-485 Serial Connection
The instrument transmits via RS-485 serial port, according to a continuous one way
protocol or a querying protocol (MODBUS RTU). The division value will be between
0 and 200000 for load cell signal values between 0 and 10 mV.
For protocol setting, see Section 4.0.
3.1 Continuous One Way Transmission Protocol
The instrument transmits the number of divisions according to a continuous protocol
via the following string:
xxxxxxCRLF
where: xxxxxx = 6 division characters (48 – 57 ASCII).
CR = 1 carriage return character (13 ASCII).
LF = 1 new line character (10 ASCII).
3.2 Modbus-RTU Protocol
The MODBUS-RTU protocol enables to manage the reading and writing of the
registers listed here below according to the specifications contained in the reference
document for this standard Modicon PI-MBUS-300.
The numerical data listed below are expressed in hexadecimal notation if preceded by
0x.
Modbus-RTU Data Format
The data received and transmitted via the MODBUS-RTU protocol has the following
format:
- 1 start bit
- 8 data bits, least significant bit sent first
- Parity none
- 1 stop bit
Of the controls available in the MODBUS-RTU protocol, only the READ HOLDING
REGISTER control may be used (code 0x03).
The interrogation frequency is linked with the preset communication rate (the
instrument will stand by for at least 3 bytes before beginning to calculate a possible
response).
Tot. bytes = 8
QUERY
Address Function Add. Reg. 1 No. register 2 bytes
A 0x03 0x0000 0x0002 CRC

12 SCT-30 Weight Transmitter Manual
Tot. bytes = 3+2*No. registers+2
where: No. of registers = number of Modbus registers to be read, starting
from register 1 address;
No. of bytes = number of following data bytes;
In the event of a string received correctly but not executable, the slave responds with
an EXCEPTIONAL RESPONSE. The FUNCTION field is transmitted with the msb
at 1.
The communication strings are controlled by CRC (Cyclical Redundancy Check).
In case of a communication error the slave will not respond with any string. The
master must allow for a time-out before response reception and if no response is
received, it infers that a communication error has occurred.
