Installation 7
2.0 Installation
Rice Lake Weighing Systems recommends the instrument and the platform (transducer) be installed on a flat level
surface, that is stable and vibration free.
2.1 Location Selection
The following should be considered when selecting a location for the equipment:
* Dust-free
* Free of strong breezes or vapors
* Moderate temperature and humidity (59 to 86°F and 40-70%)
* Use waterproof sheaths and couplings in order to protect the load cell cables
* Use a waterproof junction box to connect the cells
* Avoid welding with load cells installed
2.2 Electrical Precautionary Measures
IMPORTANT
The following electrical precautionary measures must be considered when installing this equipment:
* Main power supply must be restricted to within ± 10% of the rated voltage
*Electrical best practices must be observed by the installing technician
* Follow recommended minimal separation distances given for cable categories. See Section 2.3.
* The extension leads of the load cells, or signal amplifiers connecting to the serial ports and analog
output, must be within stated maximum lengths. See Section 2.3
* It is recommended that load cell cables are shielded and run in conduit at an acceptable distance from
power transmission lines to avoid signal interference and signal noise
* All cable runs not in conduit or otherwise shielded should be of minimal length and terminated as close
to conduit exit as possible to avoid extraneous signal noise
* If the instrument is situated inside an electric panel, the power supply cable must be shielded and as
short as possible, separate from every coil supply cable, inverter, electromotive force, etc. In addition,
dedicate an uncoupler transformer in order to feed the instrument only
* Install RC filters on the contact coils, solenoid valves and all devices producing electric disturbances
* It is recommended to leave the instrument powered on at all times to avoid condensation forming on
the inside of the instrument
2.3 Maximum Cable Length
Load Cell Cable
The maximum load cell cable length is 164' with cable 6 x 0.25 mm2.
RS-232 Cable
The maximum length of the RS-232 cable is 50' with a maximum baud rate of 19200.
RS-485 Cable
The maximum RS-485 cable length is 400'. See Section 6.2 on page 52 .
Analog Output Cable
The maximum length of the analog output cable is 300' with a cable 2 x 0.25 mm2.
The maximum length of the analog output cable is 150' with a cable 2 x 0.25 mm2.
IMPORTANT

2.4 Grounding the System
For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in
proximity of the instrument on which to connect the ground of the instrument connected cables. Connect the
ground point of the instrument, load cells and weighing structure directly to the ground bar of the electric panel or
to a grounding pole.
2.4.1 Instrument
Create a single point ground in proximity to the instrument, on which to connect the ground of the instrument and
the connected shielded cables (load cell cable, serial ports cables, etc.).
Example: use an end connector terminal block and connect this point to ground with a 4 mm2cable.
2.4.2 Load Cells and Junction Box
When the load cells are connected to the instrument through a junction box, the shielding of the cell cables and the
instrument must be connected to the grounding of the junction box.
When the load cells are directly connected to the instrument, the shielding of the cell cables must be connected to
the single point ground. Use a cable having a 4 mm² diameter, if the single ground is a few feet away; use a copper
cable having at least a 16 mm² diameter, for longer distances.
Use a ground plate of a length to obtain a total resistance of grounding lower than 1 Ω.
System cabling should be kept as short as possible to minimize noise potential. After exiting conduit or other
shielding, a ferrite should be used prior to conductor termination.

IMPORTANT
Procedures not expressly described in this manual are considered improper use of the equipment.
Ensure the platform is level or the loading cells are resting evenly.
All connections must be made with respect to local zone and environment standards.
Follow the recommended electrical precautionary measures described in Section 2.2 on page 7.
Make sure that the grounding is made correctly. See Section 2.4 on page 8.

Installation 9
2.5 Connection to the Load Cell
After proper grounding of the platform and the load cell, connect the shielded cable from the load cell to the
instrument ground. See Figure 1-1 on page 3.
The load cell terminal board of the instrument may be connected to the 6-wire load cell; 4-wire load cell must
jumper sense to the excitation.
IMPORTANT
Sense is always enabled and must be jumpered to the same polarity excitation, when not using
6-wire load cell.
The sense compensates for drops in voltage in the part of the cable connecting the instrument to the load cell. This
is useful when the distance between the instrument and the load cell is greater than 10 m. Normally this is based on
the load cell being used. When exceeding the length of the load cell cable, six wires must be used to compensate
for voltage drop. It is, however, recommended to use the cable supplied with the load cell and not to modify it in
any way.

3.0 Operation
3.1 Basic Operation
The instrument must be powered with stabilized voltage at 12 VDC or 24 VDC supplied from an AC/DC external
charger (not included) which should be connected to appropriately rated AC main voltage.

Operation 15
3.3 Multi-Range Function
The multi-range function allows for subdividing the scale capacity in two, each up to 3000 divisions.
Example: with a 10 kg cell platform it is possible to approve the weighing system with:
Single range: 6 kg capacity and 2 g division (3000 div.)
Dual range: 6/3 kg capacity and 2/1 g division (3000 + 3000 div.)
Multi-range functioning is indicated by illumination of the relative LED identifying the operating range; when
the weight on the scale enters into the second range, the division of the second range is enabled. The first
range division is restored only when the weight on the scale goes below the gross zero of the scale.
The selection of the range number with multi-range functioning is made during the instrument’s calibration.

See Section 5.0 on page 44.
3.4 Optional Date/Time Adjustment

• 4 heading lines of 24 characters
•Gross weight
• Tare weight
• Net weight
• Ticket number
• Date and time (optional)
• A Code 39 barcode (with compatible printer)
In addition each single functioning mode has specific printouts, which are described in the various operating

Weight data can also be sent to a PC, with a standard or extended string, via the printer port (/ or
// in  parameter. See Section 6.5 on page 61.).
The following conditions must be met to print:
• the weight must be stable

• printout always active
To print the totaled weight in a totalizer mode:
• the weight must be stable
•the net weight must be greater than or equal to a division, with normal or fast totalization
• the net weight must be greater than or equal to 10 divisions, with automatic totalization
Printing is reactivated depending on how the
 parameter has been set in the setup mode. See Section 3.6.2 on
page 17.
3.6.1 Printouts
If the printer is on the secondary instrument:
• The printer must be selected in both the primary instrument and the secondary instrument in the

• Press the dedicated key on the primary or secondary instrument (depending on the selected function of the
primary instrument) to print the configured printouts in the active primary instrument. To configure print
formats see section Section 6.10 on page 68.
• Press when the sum displays to execute a printout of all detected scale weights, their sum and the
heading programmed in the secondary instrument. To configure a print format see section Section 6.10 on
page 68.
To execute a printout from a primary instrument, the printer must be selected in the primary instrument
parameter. See Section 4.2 on page 32.The printer does not need to be
selected in the secondary instrument.
Note
Printing cannot be performed if a printer has been selected in the secondary instrument, but not in the primary
instrument.
If more than one primary instrument is present, the number of the primary instrument from which the weight is
taken is added to each printout on the secondary instrument.
The header is inserted by the primary instrument, if enabled.
The primary instrument adds the ticket number and time and date, if enabled.
