Symbology
Attention! This operation has to be carried out by specialized personnel.
Pay particular attention to the following indications!
Further information
Warnings
The procedures listed below have to be executed by specialized operators!
All connections have to be executed with the instrument shut off!
Identification plate of the instrument
It is important to communicate this data in case of request for information or indications concern-
ing the instrument together with the program number and the version which are shown on the
cover of the manual and are displayed when the instrument is switched on.

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.
