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
-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.

- 2 -
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.
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 top of the
display shows the gross weight; the bottom shows the response
signal of each load cell expressed in mV with three decimals.
Example: a load cell with 2.000 mV/V sensitivity provides a
response signal between 0 and 10 mV.
LOAD CELL TESTING
Load cell resistance measurement (use a digital multimeter):
-Turn off the instrument.
-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).
Load cell voltage measurement (use a digital multimeter):
-Turn on the instrument.
-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.

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 "A" filter can only be set if the instrument is connected to one load cell only.
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.

ALIBI MEMORY (ONLY FOR INSTRUMENTS WHERE THIS OPTION IS AVAILABLE)
To save a weight to the alibi memory press the key for less than 3 seconds or close the
dedicated input or send the command via serial protocol (see the Protocols manual).
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.
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.
WARNING: the alibi memory cannot store all the 999999 records; the number of records that
can be stored depends on the instrument type and on the program used.
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
 (identification): enter the ID number of your required record and confirm, the display will show:
-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.
If the entered identifier does not match any record, the message  is displayed.

OUTPUTS AND INPUTS CONFIGURATION
OUTPUTS
The outputs are set by default as follows:  / / / /.
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.
-: relay switching occurs when one of the following alarms is triggered: , ,
,  ,  , ,  ; the operation mode is forced to  (normally
closed).
If the operation mode  is selected, 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).
-: 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.
By confirming with ENTER the setpoint operation can be set to the value 0:
-: relay switching will not occur if the setpoint value is 0.
-:
-setpoint = 0 and switching = : relay switching occurs when the weight is 0; the
relay will switch again when the weight is different from zero, taking hysteresis into
account (both for positive and for negative weights).
-setpoint = 0 and switching = : relay switching occurs for a weight higher than or equal
to 0, the relay will switch again for values below 0, taking hysteresis into account.
-setpoint = 0 and switching = : relay switching occurs for a weight lower than or equal
to 0, the relay will switch again for values above 0, taking hysteresis into account.

INPUTS
Default: input 1 =  input 2 =  input 3 = 
Possible operation modes:
- (NET/GROSS): by closing this input for no more than one second, it’s making an
operation of SEMI-AUTOMATIC TARE and the display will show the net weight. To display the
gross weight again, hold the NET/GROSS input closed for 3 seconds.
-: by closing the input for no more than one second, the weight is set to zero (see section
WEIGHT ZERO-SETTING FOR SMALL VARIATIONS (SEMI-AUTOMATIC ZERO)).
-: keeping the input closed the maximum weight value reached remains on display. Opening
the input the current weight is displayed.
-: closing the input no operation is performed, the input status may however be read remotely
by way of the communication protocol.
-: closing the input for max one second the weight is transmitted over the serial
connection according to the fast continuous transmission protocol only once (only if  is
set in the item ).
-: when the input is closed the weight is displayed based on the set coefficient (see setting
of the units of measure and coefficient), otherwise the weight is displayed.
-: when the input is closed the data are sent for printing if in the communication protocol
of either serial port the parameter  is set. If the alibi memory is active, data storage is
carried out too.
SEMI-AUTOMATIC TARE (NET/GROSS)
THE SEMI-AUTOMATIC TARE OPERATION IS LOST UPON INSTRUMENT POWER-
OFF.
To perform a net operation (SEMI-AUTOMATIC TARE), close the NET/GROSS input or press the
TARE key for less than 3 seconds. The instrument displays the net weight (just set to zero) and the
NET symbol lights up. To display the gross weight again, keep the NET/GROSS input closed or
press TARE for 3 seconds.
This operation can be repeated many times by the operator to allow the loading of several products.
Example:
Put the box on the scale, the display shows the box weight; press TARE, the display shows the net
weight to zero; introduce the product in the box, the display shows the product weight. This
operation can be repeated several times.
While the net weight is displayed, keep pressed to display gross weight. When
the key is released the net weight will be displayed again.
The semi-automatic tare operation is not allowed if the gross weight is zero or negative or
unstable or above the maximum capacity.

- 14 -
PRESET TARE (SUBTRACTIVE TARE DEVICE)
It is possible to manually set a preset tare value to be subtracted from the display
value provided that the  ≤ max capacity condition is verified. In multi-
interval instruments, the max permitted value is Max1 (max capacity of range 1).
By default the instrument shows the last programmed preset tare value: to apply it press and
then ENTER.
After setting the tare value, going back to the weight display, the display shows the net weight
(subtracting the preset tare value) and the NET symbol lights up to show that a tare has been
entered. To delete a preset tare and return to gross weight display, hold down TARE for about 3
seconds or keep the NET/GROSS input (if any) closed for the same length of time (3 seconds). The
preset tare value is set to zero. The NET symbol is turned off when the gross weight is displayed
once again.
While the net weight is displayed, keep pressed to display the preset tare. When
the key is released the net weight will be displayed again.
-IF A SEMI-AUTOMATIC TARE (NET) IS ENTERED, IT IS NOT POSSIBLE TO
ACCESS THE ENTER PRESET TARE FUNCTION.
-IF A PRESET TARE IS ENTERED, IT’S STILL POSSIBLE TO ACCESS THE SEMI-
AUTOMATIC TARE (NET) FUNCTION. THE TWO DIFFERENT TYPES OF TARE ARE
ADDED.
ALL THE SEMI-AUTOMATIC TARE (NET) AND PRESET TARE FUNCTIONS WILL BE
LOST WHEN THE INSTRUMENT IS TURNED OFF.
SEMI-AUTOMATIC ZERO (WEIGHT ZERO-SETTING FOR SMALL VARIATIONS)
By closing the SEMI-AUTOMATIC ZERO input, the weight is set to zero; alternatively, by pressing
the key for less than 3 seconds, the  message is displayed for 3 seconds, by
pressing ENTER the weight is set to zero. The zero-setting will be lost upon instrument power-off.
This function is only allowed when:
-the weight is stable; otherwise the  alarm appears;
-the combined effect of the semi-automatic zero and zero tracking does not exceed 2% of the
maximum capacity, otherwise the alarm  appears.

PEAK
By keeping the PEAK input closed the maximum weight value reached remains displayed. By
opening the input the current weight is displayed.
Peak values have no legal validity.
ANALOG OUTPUT
-: it selects the analog output type (4÷20 mA, 0÷20 mA, 0÷10 V, 0÷5 V; default: 4÷20 mA).
-: choice of a weight followed by the analog output: gross () or net (). If the net
function is not active, the analog output varies according to gross weight.
- : set the weight value for which you wish to obtain the minimum analog output value.
Only set a value different from zero if you wish to limit the analog output range; for
instance: for a full scale value of 10000 kg you require an 4 mA signal at 5000 kg and
20 mA at 10000 kg, in this case, instead of zero, set 5000 kg.
- : set the weight value for which you wish to obtain the maximum analog output value; it
must correspond to the value set in the PLC program (default: calibration full scale). E.g.: if I am
using a 4÷20 mA output and in the PLC program I wish to have 20 mA = 8000 kg, I will set the
parameter to 8000.
- : analog output correction to zero: if necessary adjust the analog output, allowing the PLC
to indicate 0. The sign “-“ can be set for the last digit on the left. E.g.: if I use a 4÷20 mA output
and, with the minimum analog setting, the PLC or tester read 4.1 mA, I must set the parameter to
3.9 to obtain 4.0 on the PLC or tester.
- : correction of analog output to full scale: if necessary permit modification of the analog
output by allowing PLC to indicate the value set in the parameter  . E.g. if I am using a
4÷20 mA output with the analog set to full scale and the PLC or tester reads 19.9 mA, I must set
the parameter to 20.1 to get 20.0 on the PLC or tester.

NOTE: the analog output may also be used in the opposite manner, i.e. the weight setting that
corresponds to the analog zero ( ) may be greater than the weight set for the analog full scale
( ). The analog output will increase towards full scale as the weight decreases; the analog
output will decrease as the weight increases.
For example:
  = 10000   = 0 analog output 0÷10 V
Weight = 0 kg analog output = 10 V
Weight =5000 kg analog output = 5 V
Weight =10000 kg analog output = 0 V
All analog outputs of the instrument are ACTIVE and SINGLE ENDED type, therefore
they can be connected only to PASSIVE receiver devices. The minimum load allowed for
voltage outputs is 2 kohm, the maximum load allowed for current outputs is 400 ohm.
