Scale Interface
The W&M approved type FW-01 Scale Interface is the key component to integrate a Weighing System into your
PC. FlintWeigh does not require any separate weight display and the scale interface assures, that the weight
data will be reliably processed in the PC.
It is possible to connect up to 2 scales (up to 16x type RC3D digital load cells respective 2x type LDU digital
amplifiers) via RS485 to the scale interface, which will be connected to the PC via USB interface.
When the scales are based on standard load cells you can select among several LDU types which may be
plugged into socket within the KAL-4 junction box. The selection of the applied LDU will be defined by the
requirements for the weighing application. The technical characteristics of the LDU types and connection
details about digital and standard load cells you can find in chapter 4.
3.1. Application Range
For protecting the consumers all scales which are used for commercial transactions (legal for trade
applications) have to be calibrated in a standardized way. Typical legal for trade scales are retail scales in
shops. Privately used bathroom scales or kitchen scales are examples for scales which don’t require an
approved calibration.
Legal for trade applications
The weighing terminal has an EC type approval which covers standard load cells and scales of the accuracy
class and .
All load cells have to keep the tolerances according "OIML R60, Metrological regulation for load cells, Edition
2000".
For selecting the proper weighing module in legal for trade applications, it is required to verify the compatibility
of modules for the weighing instrument (see file KOMPMODENG.XLS on the Flintec CD-ROM).
For further information about software, alibi memory and legal for trade applications see chapter 4.
Industrial applications
All scale connections in industrial applications fall within the responsibility of the scale operator. In such
applications an approved alibi memory is not available.

5. FlintWeigh II Software Installation
Fig. 5.1 : Software source directory on the Flintec CD
Fig. 5.2 : Software target directory on the installation PC
The FlintWeigh II software displays the continuously measured weight value of the weighing system controller
within a graphical window in a legal for trade quality.
FlintWeigh II also provides an OLE interface. External programmes can access the data and information within
FlintWeigh II by using OLE functions. All windows and control buttons are part of the OLE interface.
By configuring two digital outputs and one digital input it is possible to implement a simple limit monitoring or
traffic light control.
5.1. Software Version
The software version is defined as follows:
NWxyF.exe with x = Main version no.
and y = Revision no.
5.2. Installation
It is not required to install the FlintWeigh II software in the conventional way. Just copy from the Flintec-CD to a
directory of your choice on a target PC of your choice:
these driver files are required to install the scale interface via USB connection
►the files "NW11F.exe" and " nxWeigh.dll"
e.g.: NW11F.exe Main version no. 1, Rev. no. 1
Hint: Your profile as a Windows user requires writing preferences for this installation directory. In this directory
further configuration files will be created (see chapter 5.3).
Then you connect the scale interface to an USB port of the installation PC. Hereby the installation PC
automatically detects the scale interface and the operating system will search for a suitable device driver, which
you can find in the directory “USB Driver 2008“ (Windows 7 / Vista) resp. “USB Driver 2006“ (Windows XP).
After the successful driver installation the Windows device manager should list the FlintWeigh scale interface in
the section “Connections (COM & LPT)“ listen. Please note the assigned COM port no. for further use during
the commissioning.
When started for the first time FlintWeigh II should start with the language setting "English" (see chapter 8.2).

Now the weight display (Fig. 7.1) should show a random value.
The next step is the calibration of the scale (see chapter 8.5).
7.4. Scale with Type RC3D Digital Load Cells
Important: The sensor type already has been set to “RC3D” (see Fig. 8.2; Register “Communication“).
If you have to configure a multi scale system, then select the wished scale no. ("1" or "2") within the weight
display (Fig. 7.1).
7.4.1. Preliminary Note
The next figure shows the basic principles of addressing the load cells in a weighbridge / vehicle scale. The
shown numbering simplifies the corner correction (chapter 8.4.3).
7.4.2. Define the Scale Parameters
for sensor type “RC3D“ and Single-interval scale
After activating the check box “enable” and clicking the button “RC3D“ the window
“RC3D Load Cells“ will be opened (see Fig. 8.10).
Here you select the load cells by their addresses (A, B, C, etc.). The serial numbers will
be read and displayed automatically.
If one or more address fields should have a red background, then the communication to
this/these load cell(s) is not OK. The corresponding load cells have to be checked
(address, protocoll, load etc.)

Changeover
Fig.8.11 RC3D Load cells
Single-interval The scale has exactly one weighing range with a constant
scale interval
Multi-range The scale has 2 or 3 weighing ranges with different scale
intervals. If the current gros value of the measured weight falls
within the next weighing range and larger scale interval
(changeover threshold 1 and 2), then the larger scale interval
remains active until the scale will be unloaded and will return to
the zero point.
Multi-interval The scale has 2 or 3 weighing ranges with different scale
intervals. The current gros value of the measured weight
determines the active weighing range and the active scale
interval at any time.
Step size of the display resolution for the scale respective the weighing range
Number of digits after the decimal point
Weight unit for the displayed weight: g, kg, t or lb
Condition for a stable scale (no. of scale intervals, no. of measured values);
Default: 2d and 10 values in legal for trade applications; in industrial applications these
criteria may be modified
Maximum load of the scale (as a multiple of the scale interval e1)
Minimum load of the scale (as a multiple of the scale interval e1)
Weight of the calibration weight (as a multiple of the scale interval e1)
Only for multi-range / multi-interval scales:
threshold 1/2:
Transition points for range or interval (as a multiple of the scale interval e1)
Important: For saving all scale parameter settings you have to close the window FlintWeigh II Settings
afterwards.
Now the weight display (Fig. 7.1) should show a random value.
The next step is the digital corner correction (see chapter 8.4.3).
7.4.3. Digital Corner Correction
Important: After the digital corner correction the scale always requires a new calibration.
Each corner (load cell) will be loaded one after the other with a
calibration weight (the calibration weight should be at least 10%
of max. capacity; better is 30% of max.capacity).
Using the slider the display value of the loaded load cell will be
corrected until the displayed value equals the calibration
weight.
The corner correction doesn’t depend on the sequence of the
loaded load cell, but a systematic course may spare time and
minimises the risk for errors (see chapter 8.4.1).
Hint: It may be meaningful to perform a calibration of the scale
and save the calibration data before the corner correction. This
optimises the display characteristics already before the corner
correction.
The next step is always the calibration of the scale (see chapter 8.5)
FlintWeigh Technical Manual, Rev. 3.03 November 2011
Page 20 of 32
7.5. Calibrate the Scale
Important: Before you can calibrate the scale you have to define the basic setup (see chapter 8.1) and the
scale parameters (see chapter 8.3 respective 8.4). If you have to configure a multi scale system, then select the
wished scale no. ("1" or "2") within the weight display (Fig. 7.1).
1. Open the window “nWweigh Settings“
2. Open the register “Calibration”
3. Unload the scale
4. Click the button “Dead load“; this defines the
current load status of the scale as the zero
point. The weight display should show now the
value “0”.
5. The calibration weight will be put on the centre
of the scale. The true applied weight (at least
10% of max. capacity) has to be entered into
the field “Test weight” (here 2500e = 5 kg).
6. Click the button “Gain“; now the correct gain
for the selected scale will be calculated. The
weight display should show now the value of
the calibration weight.
7. For saving the calibration data click the button
“Save calibration data”. Now a warning
appears which describes the consequences in
legal for trade applications. (“Attention! After
saving the claibration data, the internal
calibration counter (TAC) is still counted
forward. Afterwards the scale has to be reapproved by the Calibration Authority!”)
8. For confirming the saving click the button
“Save”. If you want to keep an existing
approval click the button “Cancel”.
9. After the calibration the window FlintWeigh II
Settings has to be closed. This will save all
setup changes.
10. The weight display will now show the weight of
the calibration weight, if the calibration weight
still loads the scale.
Hint: After the calibration you have to close the window FlintWeigh II Settings by clicking the button “X“ (upper
right window corner). In multi scale applications you may select and calibrate the second scale now.
FlintWeigh Technical Manual, Rev. 3.03 November 2011
Page 21 of 32
7.6. Optional Linearisation of the Scale Curve
The standard scale calibration may be supplemented by a linearisation with up to 5 correction points. Hereby
the correction points have to be in a stricly increasing order, which is:
Min. capacity < Point 1 < Point 2 < Point 3< Point 4 < Point 5 < Max. capacity of the scale
Important: Before any linearisation you have to define the basic setup (see chapter 8.1), the scale parameters
(see chapter 8.3 respective 8.4) and you have to calibrate the scale (see chapter 8.5). If you have to configure
a multi scale system, then select the wished scale no. ("1" or "2") within the weight display (Fig. 7.1).
1. Open the window “nWweigh Settings“
2. Open the register “Linearisation“
3. Correction point 1: A calibration weight will be
put on the centre of the scale. The true applied
weight as a multiple of the scale interval e has
to be entered. Then you use the slider to correct
the display value until it equals the calibration
weight
4. Define correction point 2, if applicable (this is
done like correction point 1 but uses a higher
weight)
5. Define further correction points, if applicable
6. 7. For saving the calibration data click the
button “Save calibration data”. Now a warning
appears which describes the consequences in
legal for trade applications. (“Attention! After
saving the claibration data, the internal
calibration counter (TAC) is still counted
forward. Afterwards the scale has to be reapproved by the Calibration Authority!”)
7. For confirming the saving click the button
“Save”.
.
Hint: After the linearisation you have to close the window FlintWeigh II Settings by clicking the button “X“ (upper
right window corner). In multi scale applications you may select and correct the second scale now.

Function
Fig.8.12 Example for the limit monitoring
After opening the service functions (window FlintWeigh II Settings) and selecting the register “Parameters“, you
can assign a functionality to the digital outputs:
for defining the digital outputs
Step 1: Select the source to control the output
Allowed settings are Scale 1, Scale 2 and
Combination.
Step 2: Assign a functionality to the output
Allowed settings are:
7.7.1. Setpoints and Limit Monitoring
“Off“ Without
“Limit“ Limit monitoring (see chapter 8.7.1)
“Traffic light“ Traffic light control (see chapter
8.7.2)
1. Select the scale as the source
2. Select the function “Limit“
3. Define the weight value as a multiple of interval
e; if the output shall follow the “Net value”, then
activate the associated check box
4. The output will be switched, if the “weight value
< Limit“. If the output shall show an inverse
logic, then activate the associated check box
“Exceeded”
5. By activating the check box “Input” you may use
the digital input as an additional switching
criteria for the limit monitoring: the setpoint
output will only be activated, if the digital input is
active, too
FlintWeigh Technical Manual, Rev. 3.03 November 2011
Page 23 of 32
7.7.2. Traffic Light Control
The implementation of a traffic light control requires following setup:
1. Define the function “Limit“ for digital output 1
2. Define the function “Traffic Light” for digital output 2
3. The setpoint values for both outputs have to be defined to the same value in such a way, that the
system can reliably detect an “Empty scale”
A functional setup switches the outputs as follows (vehicle scale example):
Action/Status
Output 1
(“Empty”)
Entrance Exit
Empty scale A1 = 1 Green Red
Vehicle is on the scale A1 = 0 Red
Red
Weight recorded A1 = 0 Red Green A2 = 1
Empty scale A1 = 1 Green Red
Output 2
(Weighing finalised)
A2 = 0
A2 = 0
A2 = 0
