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 mm2 cable

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).
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.

- 3 -
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

- 4 -
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.

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.
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.

ANTI PEAK
When the weight is stable, the anti peak filter removes any sudden disturbances with a maximum
duration of 1 second. Confirm the filter on the weight with ENTER and select one of the following
options:
-: anti peak filter enabled (default);
-: anti peak filter disabled.

- 14 -
ALIBI MEMORY (ONLY FOR INSTRUMENTS WHERE THIS OPTION IS AVAILABLE)
The instrument automatically saves the weight in the alibi memory during the lorry entry or exit operations.
If the net function is active, the net weight is stored; otherwise, the gross weight is stored.
Saving to the alibi memory is only possible if:
-the alibi memory is enabled;
-the weight is stable;
-the weight is above the minimum weight (20 e);
-the weight is below the max capacity;
-the weight has changed since the latest storage to alibi (see section WEIGHINGS STORAGE
AND PRINTING CONDITIONS);
An identifying number is automatically assigned to each record stored in the memory, it increases
for stored records from 1 to 999999, and is automatically reset to 1 after reaching 999999.
The alibi memory is used in a “circular” manner: when the memory end is reached, the system will
restart from the memory beginning by overwriting the first record; an alarm message is displayed
().
ALIBI MEMORY READING

-Gross weight () or net weight (); confirm with ENTER;
-Tara weight () or preset tare (), only if the recalled weight is a net weight; confirm
with ENTER;
The parameter provides the ID of the last record stored in Alibi Memory by default.

OUTPUTS AND INPUTS CONFIGURATION
OUTPUTS
The outputs are set by default as follows:
- OUT1:  / .
- OUT2:  / .
- OUT3, 4:  /  /  /  / .
Possible operation modes:
- (normally open): the relay is de-energised and the contact is open when the weight is
lower than the programmed setpoint value; it closes when the weight is higher than or equal to
the programmed setpoint value.
- (normally closed): the relay is energised and the contact is closed when the weight is
lower than the programmed setpoint value; it opens when the weight is higher than or equal to
the programmed setpoint value.
-: the contact will switch on the basis of weight, according to setpoint (see section SETPOINT
PROGRAMMING).
-: the contact will not switch on the basis of weight, but is controlled by remote protocol commands.
-: relay switching occurs when the weight is stable.
-: (OUT 1 only): connect to the green light of the signal station.
-: (OUT2 only): connect to the red light of the signal station.
If the operation mode  is selected and the net functions are enabled, the following options are
also active:
-: the contact will switch on the basis of gross weight.
-: the contact will switch on the basis of net weight (If the net function is not active, the
contact will switch on the basis of gross weight).
If net functions are disabled (see parameter  in section INFO MENU), by
selecting  the operating mode  will be activated.
-: relay switching occurs for both positive and negative weight values.
-: relay switching occurs for positive weight values only.
-: relay switching occurs for negative weight values only.
