Intended Use, not intended Use
A device from Lorenz Messtechnik GmbH is used for display, processing and control of processes. It
must not be used as the sole means of averting dangerous conditions on machines and systems.
Machines and systems must be designed in such a way that faulty states cannot lead to a dangerous
situation for the operating personnel (e. g. through independent limit value-switches or mechanical
interlocks). In particular, it must be ensured that a the device, its malfunction or its failure does not
lead to damage to property or a loss of that can lead to danger to people. It is also important to prevent
the precautions that are taken from being cannot be circumvented for the safety of a plant. Emergen-
 cystopdevicesmustremaine󰀨ectiveatalltimes.
Installation Instructions
Devices from Lorenz Messtechnik GmbH must be installed and connected in compliance with the
relevant DIN and VDE standards. They must be installed in such a way that unintentional operation
 issu󰀩cientlyexcluded.Topreventaninterruptionofthesupplyandsignallinesfromleadingtoan
 undenedor dangerousstate, appropriatehardware andsoftware safetyprecautions mustbe ob-
served.Supply and signallines mustbeinstalled insuch a waythat theydonot interferewith the functionof
the Lorenz Messtechnik GmbH by interfering signals (such as inductive or capacitive interferences).
Notes on Malfunctions, Maintenance and Repair
The devices do not contain any parts that require or can be serviced by the user. Repairs may only
be carried out by Lorenz Messtechnik GmbH. If it can be assumed that safe operation of the device is
no longer possible, it must be put out of operation immediately and secured against unintentional
operation. This applies in particular if:
• The device is visibly damaged
• The device is no longer functional
• Parts of the appliance are loose
• The connecting lines are visibly damaged
In addition, we would like to point out that all obligations of Lorenz Messtechnik GmbH arise exclusi-
vely from the respective purchase contract in which the warranty is conclusively stated.

2.2 Intended Use
Devices from Lorenz Messtechnik GmbH are to be used exclusively for measuring tasks and the di-
rectly associated control tasks. Any use beyond thisis considered to be improper.
The valid legal and safety regulations must be observed during measurement. The instrument is not
a safety component in the sense of its intended use and it is transported and stored properly. The
installation and commissioning, the operation and the disassembly must be carried out professionally.
2.3 General Hazards in the Event of non-compliance with the Safety
Instructions
The device complies with the current safety requirements. Residual dangers can emanate from the
device if it is improperly used and operated by untrained personnel. Any person entrusted with the
installation, operation, maintenance and repair of the device must read and understand the operating
instructions and, in particular, the safety instructions.
Incorrect use (e. g. by untrained personnel) may result in residual hazards. The operating instructions
must be read and understood by all persons involved in the installation, commissioning, maintenance,
repair, operation and dismantling of the device is trusted. The device must not be used if visible da-
mage is visible.
2.4 Residual Hazards
The system planner, equipment supplier and operator must plan, implement and be responsible for
the safety of the equipment. Other hazards must be minimized. The residual dangers of the measure-
ment technology must be pointed out and human error must be taken into account. The design of the
system must be suitable for avoiding hazards - a hazard analysis must be carried out for the system.
The applicable regulations and laws are as follows to note.
3 Safety and Warning Notices
3.1 Symbols

4 Preamble
4.1 Product Description
 TheSI-USB3isameasuringamplierwithuptofourindependentinputchannels.Eachinputchannel
is displayed as a separate device on a PC (virtual serial interface). Each measuring channel can be
individually set in the factory for a physical quantity or a sensor.
The following sensor signals are currently available:
Strain gauge signals: ±3 mV/V (corresponds ±30000 digits)
Active signals with voltage input: ±5V (corresponds ±25000 digits)
Active signals with voltage input: ±10V (corresponds ±25000 digits)
Active signals with current input: 0 ... 20 mA (corresponds 0 ... 20000 digits)
Active signals with current input: 4 ... 20 mA (corresponds 0 ... 20000 digits)
Active signals with current input: 10 ±10 mA (corresponds 0 ... 20000 digits)
Active signals with current input: 12 ±8 mA (corresponds 0 ... 20000 digits)
Linear potentiometer: 0 ... 5V (corresponds 0 ... 25000 digits)
Temperature measurement: - 200 ... 860 °C (corresponds - 6400 ... 27520 digits)
 Quadratureencoder:   5VTTL  (corresponds±32511digits)

Warning: Please pay attention to the signal type of the sensor when connecting the sensor.
  Connectingthesensorwiththewrongsignaltypecandamagetheamplierandthesensor.
The Lorenz USB drivers are required for the operation on a PC. They are available for download on
our website. Guidance is available in document no. 090235.
For the operation of the SI-USB3 we recommend the software VS3. It is available for download on our
website. Guidance is available in document no 090367.
Among others, this software provides following functions:
• CongurationpossibilitiesfortheVS3
• Storage of sensor-related scaling and adjustment data
• Display for the presentation of measured data
(actual value, tare value, minimum value and maximum value)
• Presentation of the measured data in a diagram
• StorageofmeasureddatainCSV-format(outputcongurable)
• Storage of the diagram in BMP-format (output size adjustable)
• Print-outofthediagramwithdateanddenablesuperscription
• Presentation of the sensor information
The communication protocol is available for the development of your own applications. The English
protocol description is available in document no. 90110 on our website.
4.2 Safe and correct Use
Warning: Observe the correct sensor adjustment.
ConsiderthecorrectVS3conguration.
Chooseasignicantleidentication/prexwhenstoringmeasureddata.
Fasten housing, ground, connect power supply, protect from splash water and do not pull
the cable.

It is important to ensure that there is no interchanging of the sensors, e. g. if a measuring
chain exists.
The power is supplied either via the black power supply socket with a separately delivered power sup-
ply unit or via the green socket. Again, the polarity is independent for both power supply sockets. The
middle PIN is the shield for the green socket.
Or
+ - - +
The four sensors are signed with Sensor 1 - 4. First the power supply must be connected. When a
sensor is connected, the corresponding power LED is activated. Only when a PC/Laptop connection
via the USB socket on the back exists, the Link-LED is activated. If the Link-LED is dark, check again
the connection SI-USB3 to the PC/Laptop. Temperature measurements are possible at sensor con-
nection 1 and/or sensor connection 4.
