Power supply of the instrument
The instrument is powered via terminals 14 and 15.
The power cable must be routed separately from other power cables with different voltages,
load cell cables and logic inputs / outputs.
Supply voltage: 12 – 24 V ca ± 15%, 4 VA
Terminal board connection: 14 – Power supply +
15 – Zero
Connection of the load cells
The cell (or cells) cable(s) must not be channeled with other cables (for example outputs
connected to contactors or power cables), but must follow its own path.
Any cable extension connections must be carefully shielded, respecting the color code and
using the cable of the type supplied by the manufacturer. The extension connections must
be made by welding, or through support terminal blocks or through the junction box supplied
separately.
The cell cable must have a number of conductors not higher than those used (4 or 6). In the
case of a multi-conductor cable, connect the remaining wires to the cell power supply (termi-
nal 2)
Up to a maximum of 4 350 ohm cells in parallel can be connected to the instrument. The supply voltage of the
cells is 5 V direct current and is protected against a temporary short circuit. The measuring range of the instru-
ment involves the use of load cells with sensitivity from 1 mV / V to 3 mV / V. The cable of the load cells must
be connected to terminals 1 ... 6 of the removable terminal board. In the case of a 4-conductor cell cable,
connect the cell power terminals to the respective polarity of the reference terminals (1-4 2-3).
Connect the shield of the cell cable to terminal 1!

Connection logical input
The logic input is isolated from the instrument through an optocoupler.
The connection cable of the logic input must not be channeled with power or power cables
Use a connection cable as short as possible (no longer than 5 meters). If a longer length is
required, use a relay relay.
In the case of DC power supply (e.g.24 V dc) and a long or disturbed input connection cable,
we recommend connecting pin 13 (input) and 14 (+ power supply) instead of 12 and 13
Relay output connection
The three outputs are relayed with three commons. The capacity of each contact is 24 V DC / VAC 0.5 A.
Serial RS485 connection
The cable must not be channeled with other cables (e.g. outputs connected to remote control
switches or power supply cables), it must possibly follow its own path.

Serial RS232 connection
To make the serial connection, use a shielded cable, taking care to connect the screen to
ground at only one of the two ends. If the cable has more conductors than those used, con-
nect the free wires to the screen.
The serial connection cable must have a maximum length of 15 meters (EIA RS-232-C stand-
ards), beyond which it is necessary to adopt the RS422 interface with which the instrument
is equipped.
The cable must not be channeled with other cables (e. g. outputs connected to remote control
switches or power cables), but it must possibly follow its own path.
The PC used for the connection must comply with the EN 60950 standard.
The connection diagram with a 9-pole PC connector is shown below:
Connection of analog output (optional)
The instrument, when it is in this hardware configuration, provides an analogue output in current or in voltage.
Characteristics
Analogue voltage output: range from 0 to 10 volts or from 0 to 5 Volts, minimum load 10 kΩ
Analogue current output: range from 0 to 20mA or from 4 to 20mA, maximum load 300Ω
The settings for the type of analog output supplied (voltage or current) are determined at the factory and must
be specified at the time of purchase.
To make the connection use a shielded cable, taking care to connect the screen to ground
at only one of the two ends.
Analogue transmission is particularly sensitive to electromagnetic disturbances; it is there-
fore suggested that the cables are as short as possible and that they follow their own path.

Termination resistance RS485 and RS422
The transmission of the RS485 / RS422 link bus is of the differential type, i. e. the signal is the result of the
difference between the voltages of the two wires that make up the bus.
The RS485 / RS422 transmitters provide (under load) an output level of ± 2-3V between outputs A and B; the
receivers recognize levels up to ± 200 mV as a valid signal.
This technique allows an excellent noise immunity even on very long cable runs. To make the line more im-
mune to noise, the first and last device on the network should have a termination resistance connected in
parallel with the line.
Typically, it is necessary to use termination resistors whose value ranges from 120 to 560 ohms. When the
terminating resistors are present, there must also be the polarization resistors of the two lines, which are nor-
mally present in the master (PLC) or connectors, so that at rest the difference in potential between the two
lines is greater than 200 mV, as required by the RS485 specification.

In the case of connection to two RS422 pairs and two nodes,
the resistors are placed near the farthest receiver and the
value can go down to 120 Ohm (figure on the side).
n the case of connection to two
RS422 but multi-node pairs,
the same 120 Ohm value is
indicated in the figure opposite,
but this applies to very long
lines (hundreds of meters). In
the case of shorter lines the
resistances must be increased
because the total impedance with the 120 Ohms would be a little too low, 60 Ohm without counting the load
of the receivers, so it would be better to use resistors of about ~ 250 Ohm.
The same goes for the
RS485 connection. Use 250
Ohm resistance for non-
excessively long lines.

User manual
Main characteristics of use
The main operating characteristics are:
Weight control detected by alarm and pre-alarm thresholds
Alarm due to cell failure or power failure
Display signals
The weight of the scale is normally displayed on the 6-digit display. According to the various programming
procedures, the display is used for programming the parameters to be inserted in the memory, ie messages
indicating the type of operation being carried out and therefore helping the operator in the management and
programming of the instrument.
When the instrument is switched on, the display is tested, and then a code
identifying the software and its version appears. It is important to communi-
cate these codes in case of request for assistance.
When a programming procedure is not in progress, the display shows the measured weight expressed in kg.
Under certain conditions, the following messages are reported:
Signal weight not detectable
Weight signal not detectable.
Signal of underweight
Indication of weight outside the negative reading range.
Overload signal
When the gross weight in the scale exceeds the maximum load capacity of the weigh-
ing system by more than 9 divisions, the display shows this message (see page 36).
LED indicators (red)
Near the display, there are 2 LEDs that indicate respectively if there is a tare (the LED on the left is lit) and if
the weight is stable (the LED on the right is on).
Other LED indicators (green)
Near the relays there are three indicator LEDs that are on when the relative relay is energized.

Use of the keyboard
The instrument is programmed and controlled through the keypad consisting of 4 keys, all with multiple func-
tions. The instrument, according to the operation in progress, automatically stabilizes the selection of one of
the key functions.

Data setting
Restore zero (semi-automatic zero)
This operation is performed to correct small shifts of the zero of the instrument.
The gross weight reset command is not executed under the following conditions:
Weight instable (the weight does not stabilize within 3 seconds of the reset command)
When the gross weight, compared to the original zero calibration, is greater (positive or negative) than
200 divisions
The operation to reset the gross weight is maintained when the instrument is switched off.
Self weighing tare (autotare)
The auto tare command is not executed under the following conditions:
Unstable weight (the weight does not stabilize within 3 seconds of the auto tare command).
Gross weight negative

Input and output
Input
1 Reset displayed value (auto tare)
Output
1 Set-point output 1 positive intervention
2 Set-point output 2 positive intervention
3 Set-point output 2 positive or negative intervention
The relays are normally energized.
When a set point is exceeded, the relative relay de-energizes.
When a set point has a value of zero, its output is always de-energized.
All relays de-energize (alarm condition), when the following conditions occur: cell cable breakages or weight
outside the nominal range (NO CON) or exceeding the maximum weight (upper dashes).
Commissioning the instrument
To put the instrument into operation, after installation and wiring of the connections, the following operations
must be carried out:
Set the weight calibration data
Perform the weight calibration
Set the parameters and set-points according to your needs
Pagina – page – Seite 13

Calibration data menu
Weighing system capacity
Set the value corresponding to the sum of the nominal capacities of the load cells,
in kg. This data constitutes the full scale value of the weighing system. Values
between 1 and 60,000 kg are accepted. After a change, the set points are reset.
Password protected setting.
Sensibility
Set the sensitivity of the load cells to perform a theoretical weight calibration.
After a change, the set points are reset. Password pro-setting.
Divisions value
The division value is expressed in kg, selectable between 0.001 kg and 50 kg.
The ratio between the maximum system capacity and the division value
constitutes the resolution of the system (number of divisions). The number of
divisions must be at least 100.
If the instrument is switched off without leaving the set-up menu, the programmed settings will
not be memorized.
To access the calibration settings use the 2792 password.

Weight calibration and linearization
During the calibration phase, the display shows the weight intermittently with the word "CAL".
During the linearization phase the display shows the weight intermittently with the wording "LIN n" where in-
stead of n there is the number of the point to be set (from 1 to 9).
Zero calibration
Carry out the operation with the scales unloaded but complete with the tare weight, with stabilized weight. The
displayed weight must be reset. This operation can be repeated several times.
Full scale calibration
Before carrying out the operation, load the sample weight on the scale and wait for it to stabilize; the display
shows the measured value to be calibrated. If the set value is higher than the resolution offered by the instru-
ment, it is not accepted and the display shows an error message for a few seconds. It is always possible to
repeat the calibration operations.
If the instrument is switched off without leaving the set-up menu, the programmed settings will
not be memorized.

Weighing parameters setting menu
Weight filter
This parameter adjusts the action of the digital filter applied to the detected weight.
If a low value is programmed the filter action is lower, by programming a high value
the weight is more filtered (minimum value 0, standard value 5, max value 9).
In the first case, a faster response of weight variations is obtained.
In the second one, we get a slowing of the weight response on the display, which
allows to absorb oscillations or vibrations of the weighing system.
Weight stability
The weight is considered stable when it is kept within a certain range for a certain
period of time.
Value Variation
0 Stability determined very quickly.
1 Stability determined quickly.
2 Stability determined with average parameters.
3 Stability determined accurately.
4 Stability determined very accurately.

Autozero at power up
This parameter is the maximum weight zeroed at power up. The auto-zero func-
tion consists in carrying out an automatic zero calibration when the instrument is
switched on, only if the detected weight stabilizes within the set threshold. To
disable the function, set the value 0.
Tracking of zero
When the scales are discharged, the instrument automatically corrects small and
slow weight variations (positive or negative) compared to the zero scale.
Value Variation
0 Tracking function of zero excluded.
