1 USER WARNINGS
RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT
-Keep away from heat sources and direct sunlight
-Repair the instrument from rain (except special IP versions)
-Do not wash with water jets (except special IP versions)
-Do not dip in water
-Do not spill liquid on the instrument
-Do not use solvents to clean the instrument
-Do not install in areas subject to explosion hazard (except special Atex versions)
2 RECOMMENDATIONS FOR CORRECT INSTALLATION OF WEIGHING
INSTRUMENTS
The terminals indicated on the instrument’s wiring diagram to be connected to earth
must have the same potential as the weighed structure (same earthing pit or earthing
system). If you are unable to ensure this condition, connect with an earthing wire the
terminals of the instrument (including the terminal 0 VDC) to the weighed structure.
The cell cable must be individually led to its panel input and not share a conduit with
other cables; connect it directly to the instrument terminal strip without breaking its
route with support terminal strips.
Use “RC” filters on the instrument-driven solenoid valve and remote control switch coils.
Avoid inverters in the instrument panel; if inevitable, use special filters for the inverters and
separate them with sheet metal partitions.
The panel installer must provide electric protections for the instruments (fuses, door lock switch
etc.).
It is advisable to leave the equipment always switched on to prevent the formation of
condensation.
MAXIMUM CABLE LENGTHS
RS485: 1000 metres with AWG24, shielded and twisted cables
RS232: 15 metres for baud rates up to 19200

3 RECOMMENDATIONS FOR CORRECT INSTALLATION OF THE LOAD CELLS
SIZING OF LOAD CELLS CAPACITY
For safety reasons, in case of static weighing, it is advisable to use the load cells at a
maximum of 70-80% of its nominal capacity (assuming that the load is uniformly distributed
over the entire weighed structure); depending on the handling mode of the load to weigh,
consider to further reduce the % of load with respect to the nominal capacity (ex.: forklifts
handling, bridge cranes, etc.).
In case of weighing with dynamic loads, the installer has to estimate the thrust speed, the
acceleration, the frequency, etc.
INSTALLING LOAD CELLS
The load cells must be placed on rigid, stable in-line structures; it is important to use the
mounting modules for load cells to compensate for misalignment of the support surfaces.
PROTECTION OF THE CELL CABLE
Use water-proof sheaths and joints in order to protect the cables of the cells.
MECHANICAL RESTRAINTS (pipes, etc.)
When pipes are present, we recommend the use of hoses and flexible couplings with open
mouthpieces with rubber protection; in case of hard 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).
CONNECTING SEVERAL CELLS IN PARALLEL
Connect several cells in parallel by using - if necessary - a watertight junction box with
terminal box. The cell connection extension cables must be shielded, led 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 4x1 mm2minimum 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 - KNOCKS – 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 plant is
protected against lateral shifting and tipping relating to: shocks and vibration; windy
conditions; seismic conditions in the installation setting; stability of the support structure.

User manual WTS Ver.1.16
Seite 6von 52
EARTHING THE WEIGHED STRUCTURE
By means of a copper wire with suitable cross-section, connect the cell upper support plate
with the lower support plate, then connect all the lower plates to a single earthing system.
Electrostatic charges accumulated because of the product rubbing against the pipes and the
weighed container walls are discharged to the ground without going through or damaging the
load cells. Failure to implement a proper earthing system might not affect the operation of the
weighing system; this, however, does not rule out the possibility that the cells and connected
instrument may become damaged in the future. It is forbidden to ensure earthing system
continuity by using metal parts contained in the weighed structure.
FAILURE TO FOLLOW THE INSTALLATION RECOMMENDATIONS WILL BE
CONSIDERED A MISUSE OF THE EQUIPMENT

3.1 LOAD CELL INPUT TEST (QUICK ACCESS)
From the weight display, press for 3 seconds; the response signal of the load cells is
displayed, expressed in mV with four decimals.
3.2 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 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 cell wire and between any other 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):
Take out the load cell to be tested from underneath the container, or alternatively, lift the
container support.
Make sure that the excitation of two wires of the load cell connected to the instrument (or
amplifier) is 5 Vdc ±3%.
Measure the response signal between the positive and the negative signal wires by directly
connecting them to the tester, and make sure that it is comprised between 0 and ±0.5 mV
(thousandths of a Volt).
Apply load to the 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.

9 PROGRAMMING OF SYSTEM PARAMETERS
From the weight display, press simultaneously keys and to access the parameter
setting.
: to enter a menu/confirm the data entry.
: to modify the displayed value or menu item.
: to select a new value or modify the displayed menu item.
: to cancel and return to the previous menu.
9.1 THEORETICAL CALIBRATION
This function allows the load cell rated values to be set.
To perform the theoretical calibration set the following parameters in sequence:
-

(default:

): the system full scale is given by one cell capacity multiplied by
the number of cells used. Example of system full scale value calculation: 4 cells of 1000kg
FULL SCALE = 1000 X 4 = 4000. The instrument is supplied with a theoretical full scale
value

corresponding to 10000. To restore factory values, set 0 as full scale.
-

(default: 2.00000 mV/V): sensitivity is a load cell rated parameter expressed in mV/V.
Set the average sensitivity value indicated on the load cells. It’s possible to set a value between
0.50000 and 7.00000 mV/V. Example of 4-cell system with sensitivity: 2.00100, 2.00150,
2.00200, 2.00250; enter 2.00175, calculated as (2.00100 + 2.00150 + 2.00200 + 2.00250) / 4.
-

:the division (resolution) is the minimum weight increment value which can be
displayed. It is automatically calculated by the system according to the performed
calibration, so that it is equal to 1/10000 of full scale. It can be changed and be variable
between 0.0001 and 100 with x1 x2 x5 x10 increments.
-By modifying the theoretical full scale or the sensitivity, the real calibration is
cancelled and the theoretical calibration only is considered valid.
-If the theoretical full scale and the recalculated full scale in real calibration (see
section REAL CALIBRATION (WITH SAMPLE WEIGHTS)) are equal, this
means that the calibration currently in use is theoretical; if they are different, the
calibration in use is the real calibration based on sample weights.
-By modifying the theoretical full scale or the sensitivity, the system’s parameters
containing a weight value will be set to default values (setpoint, hysteresis, etc.).

User manual WTS Ver.1.16
Seite 16 von 52
9.1.1 MAXIMUM CAPACITY

: Maximum displayable weight (from 0 to full scale; default: 0). When the weight exceeds
this value by 9 divisions the following is displayed ‘

’. To disable this function, set 0.
9.1.2 TARE WEIGHT ZERO SETTING
This menu may also be accessed directly from the weight display, holding down the
key for 3 seconds.
Perform this procedure after having set the THEORETICAL CALIBRATION data.
Use this function to set to zero the weight of the empty system after commissioning and then
later on to compensate zero variations due to the presence of product residues.
Procedure:
-Confirm the message

(Zero) by pressing .
-The weight value to be set to zero is displayed. In this phase all of the LEDs are flashing.
-Confirming once again, the weight is set to zero (the value is stored to the permanent
memory).
-Press to display the value of the total weight reset by the instrument, given by the
sum of all of the previous zero settings.
9.1.3 ZERO VALUE MANUAL ENTRY
WARNING: Perform this procedure only if it’s not possible to reset the weighed structure
tare, for example because it contains product that can not be unloaded.
Set in this parameter the estimated zero value (from 0 to 999999; default: 0).

User manual WTS Ver.1.16
Seite 17 von 52
9.2 REAL CALIBRATION (WITH SAMPLE WEIGHTS)
After having performed the THEORETICAL CALIBRATION and TARE WEIGHT ZERO
SETTING, this function allows correct calibration to be done using sample weights of
known value, if necessary, any deviations of the indicated value from the correct value
to be corrected.
Load onto the weighing system a sample weight, which must be at least 50% of the maximum
quantity to be weighed.
By confirming the message

the flashing value of the weight currently on the system is
displayed. In this phase all of the LEDs are off. Adjust the value on display by using the arrow
keys if necessary. After confirming, the new set weight will appear with all the LEDs flashing.
After an additional confirmation, the message

will be restored and by repeatedly
pressing the key the weight will once again be displayed.
Example: for a system of maximum capacity 1000 kg and 1 kg division, two sample
weights are available, one of 500 kg and the other one of 300 kg. Load both weights onto
the system and correct the indicated weight to 800. Now remove the 300 kg weight, the
system must show 500; remove the 500 kg weight, too; the system must read zero. If this
does not happen, it means that there is a mechanical problem affecting the system
linearity.
CAUTION: identify and correct any mechanical problems before repeating the
procedure.
-If theoretical full scale and recalculated full scale in real calibration are equal, it
means that the theoretical calibration is currently in use; otherwise, the real
calibration based on sample weights is in use.
-If the correction made changes the previous full scale for more than 20%, all the
parameters with settable weight values are reset to default values.
LINEARISATION OPTION ON MAX 8 POINTS:
It is possible to perform a linearisation of the weight repeating the above-described
procedure up to a maximum of eight points, using eight different sample weights. The
procedure ends by pressing the button or after entering the eighth value; at this
point it will no longer be possible to change the calibration value, but only to perform a new
real calibration. To perform a new calibration, should return to the weight display and then re-
entering into the calibration menu.
By pressing after having confirmed the sample weight that has been set, the full scale
appears, recalculated according to the value of the maximum sample weight entered and
making reference to the cell sensitivity set in the theoretical calibration (

).

9.3 FILTER ON THE WEIGHT
Setting this parameter allows a stable weight display to be obtained.
To increase the effect (weight more stable) increase the value (from 0 to 9, default
4).
As seen in the diagram:
-By confirming the

message, the currently programmed filter value is displayed.
-By changing and confirming the value, the weight is displayed and it will be possible to
experimentally verify its stability.
-If stability is not satisfactory, confirming brings back the message

and the filter may
be modified again until an optimum result is achieved.
The filter enables to stabilise a weight as long as its variations are smaller than the
corresponding “Response Time”. It is necessary to set this filter according to the type of
application and to the full scale value set.

If the print function is enabled, the symbol corresponding to the selected unit of measure will
be printed after the measured value.
For the units marked with * it’s possible to set also the display coefficient
(parameter

, see the related paragraph). To use

is necessary to
enable it, closing the

input (see paragraph OUTPUTS AND INPUTS
CONFIGURATION).
9.5.1 DISPLAY COEFFICIENT
By setting the coefficient

the display is changed accordingly.
If one of the inputs is set to

 mode (see paragraph OUTPUTS AND INPUTS
CONFIGURATION) when the input is closed the value will be displayed modified according to
the

coefficient; when the input is opened the standard weight display will be restored.

: (max settable value: 99.9999; default: 1.0000) will have different meanings according to the
value set in

, i.e. the selected unit of measure. (see paragraph SETTING UNITS OF
MEASURE).
