Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Security messages
Note
For its automation and drives product portfolio, Siemens provides IT security mechanisms to
support secure operation of the plant/machine. Our products are continuously being further
developed also taking into account the aspect of IT security. We therefore recommend that
you regularly check for updates of our products and that you only use the latest versions.
You will find information on this in:
Industrial Security (http://www.siemens.com/industrialsecurity)
Here, you can register for a product-specific newsletter.
For the secure operation of a plant/machine, it is also necessary to integrate the automation
components in a full IT security concept for the entire plant/machine that represents the state
of the art in IT technology. You will find information on this in:
Industry Online Support
(http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo2&aktprim=99&lang=en)
Products from other manufacturers that are being used must also be taken into account.

System expansions
Install only system expansions that are intended for this device. Installing other expansions
can damage the system or violate the safety provisions and regulations for radio interference
suppression. You can obtain information on system expansions suitable for installation from
the technical customer service or from the sales office responsible for your area.
NOTICE
Invalidation of the warranty
Any damage to the device caused by installing or replacing system expansion products will
void the warranty.
NOTICE
Voltage can destroy electrostatic-sensitive modules
The device contains modules that are sensitive to electrostatic discharge. Modules that are
sensitive to electrostatic discharge can be destroyed by voltages well below those that can
be perceived by human beings. Such voltages occur if you touch a component or electrical
connectors of a module without first discharging the static from your body. The damage
caused by overvoltage on a module cannot normally be detected immediately and only
becomes apparent after a longer period of operation.
Measures for protecting against discharge of static electricity:
•Before working with modules, make sure that you discharge static from your body, for
example by touching a grounded object.
•The devices and tools used must also be free of static charges.
•Disconnect the power supply.
•Hold modules only by their edges and do not touch any connector pins or conductors.
Connecting the 24 V DC power supply
WARNING
The device should only be connected to a 24 V DC power supply which satisfies the
requirements of safe extra low voltage (SELV).
When the device is operated on a wall, in an open rack or other similar locations, an NEC
Class 2 current source is required for the compliance of the UL requirements (in
accordance with UL 60950-1). In all other cases (according to IEC/EN/DlN EN 60950-1), a
current source with limited power (LPS = Limited Power Source) is required.
24 V DC supply voltage (19.2 to 28.8 V)
The generation of the 24 V DC supply voltage by the line-side power supply must be
implemented as functional extra-low voltage with safe electrical isolation according
(floating) to IEC 80364-4-41, or as SELV to IEC/EN/DlN EN 60950-1 and LPS/NEC class 2.

Description 3
3.1 Area of application
The SIMATIC MV400 family of readers are optical code readers designed specifically for the
recognition and evaluation of numerous machine-readable codes and plain text in industrial
production.
The list of readable codes includes all common matrix and barcodes that can usually be
detected reliably regardless of the print technique or the carrier medium used.
In the SIMATIC MV400 device family, particular emphasis was placed on:
● Ruggedness
● Reliability
● Ease of operation
This applies both to the mechanical properties and the high-quality image processing
functions of all devices in the SIMATIC MV400 product family.
SIMATIC MV440 can also verify the code quality of codes according to commonly applied
standards. The reader calculates the quality of applied codes and therefore allows quality
control of the marking process.
Key functions of the reader
The main functions of the reader are reading codes and grading the code quality. The area
of application of the SIMATIC MV400 product family covers practically all areas of industrial
production. Potential uses range from recognition of stationary parts to fast moving parts on
conveyor systems.
Available versions
SIMATIC MV420
● SIMATIC MV420 is available with an integrated lens and lighting.
● SIMATIC MV420 has an ingress protection rating of IP67.
● SIMATIC MV420 is available in parts (base unit, ring light, lens).
SIMATIC MV440
● High-performance integrated lighting is available for SIMATIC MV440.
● The device can be adjusted for nearly all read distances and code sizes with a C/CS
mount lens. IP67 is also possible for this version with the lens cover.
● SIMATIC MV440 is also available in 3 different resolutions.

Industrial applications
The readers are therefore suitable for all industrial applications where direct marking (Direct
Part Marking – DPM), tracking and serialization of production parts are used. This applies
equally to production processes and logistics processes.
Communication Interfaces
The readers have all the common communications interfaces of industrial sensors and can
therefore be connected to a wide variety of systems. The MOBY-ASM interface allows
seamless combination with the RFID industrial standard MOBY and means that many
communications modules available in the MOBY system (ASMs) can be used, for example
for PROFIBUS.
Simple operation and commissioning
Despite the wide range of possible applications, a main feature of the readers is their ease of
operation and commissioning. For most applications, the parameters are set automatically.
If, however, readjustment becomes necessary, the parameters can be assigned using the
integrated Web server and an Internet browser without prior software installation.
As of release 04/2011, all SIMATIC MV440 readers can also be suppled by
Power over Ethernet (PoE) which further simplifies installation.
The Text-Genius license is available for SIMATIC MV440 readers as of release 09/2012.
This provides a reliable read function not just for standard plain text, but also for customer-
specific fonts.
