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)
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 –SUPPLY) 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
-Analog current output: up to 500 metres with 0.5 mm2 cable
-Analog voltage output: up to 300 metres with 0.5 mm2cable
RECOMMENDATIONS FOR CORRECT INSTALLATION OF THE LOAD CELLS
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).

- 2 -
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.
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

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.
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.
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.
-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.

BUFFER BATTERY
The instrument is equipped with an internal battery that allows to keep active the internal clock even
in the event of power failure.
At the first start and after long periods of inactivity, leave the instrument on for at least 12
hours to fully charge the battery.
AFTER A BLACKOUT
After a blackout the instrument DOES NOT come on again automatically, you have to press ON.
To guarantee an automatic restart after a blackout, disable the ON key as follows:
-disconnect power supply and open the instrument;
-identify flat connectors coming from the keypad on the main board;
-extract the 4-pole connector;
-short-circuit the following pins using the unused jumper inside the instrument:
▫WDESK: the two pins further in compared to the main board (see picture to the left);
▫WTAB / WINOX: the two outer pins compared to the main board (see picture to the right);
-connect the 4-pole flat to the two pins still free complying with initial orientation.

INSTRUMENT COMMISSIONING
To turn on the instrument press ON. To turn it off press OFF for about 3 seconds: when 
appears release the key.
After a blackout the instrument DOES NOT come on again automatically, you have to press ON.
To guarantee an automatic restart after a blackout, disable the ON key (see section AFTER A
BLACKOUT).
Upon switch-on, the display shows in sequence:
- →  (ONLY in case of approved program);
-instrument model (e.g.:  or  or );
- followed by the software code (e.g.:  );
-program type:  (bridge);
-followed by the software version (e.g.:  );
- followed by the hardware code (e.g.:  );
-serial number (e.g.: );
Check that the display shows the weight and that when loading the load cells there is an increase in
weight. If there is not check and verify the connections and correct positioning of the load cells.
-If the instrument has already been theoretical CALIBRATED (plant system identification tag
present on the instrument and on the cover: load cell’s rated data already entered):
▫Reset to zero (see section TARE WEIGHT ZERO SETTING).
▫Check the calibration with sample weights and correct the indicated weight if necessary (see
section REAL CALIBRATION (WITH SAMPLE WEIGHTS)).
-If the instrument HAS NOT BEEN CALIBRATED (missing plant system identification tag)
proceed with calibration:
▫If load cells data are unknown, follow the procedure in section REAL CALIBRATION (WITH
SAMPLE WEIGHTS).
▫Enter the rated data of load cells following the procedure given in section THEORETICAL
CALIBRATION.
▫Reset to zero (see section TARE WEIGHT ZERO SETTING).
▫Check the calibration with sample weights and correct the indicated weight if necessary (see
section REAL CALIBRATION (WITH SAMPLE WEIGHTS)).
-Select the printer model used (see section SERIAL COMMUNICATION SETTING).
-Set instrument’s clock with current date and time (see section DATE AND TIME SETTING).

PROGRAMMING OF SYSTEM PARAMETERS
From the weight display, press simultaneously keys MENU and ESC to access the parameter setting.
MENU/ENTER: to enter a menu/confirm the data entry.
▲▼: to modify the displayed figure or menu item.
◄►: to select a new figure.
ESC: to cancel and return to the previous menu.
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: 4 cells of 1000 kg 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, the sensitivity or divisions, 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, the sensitivity or divisions, the system’s parameters
containing a weight value will be set to default values (setpoint, hysteresis, etc.).
