2.5 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation) are
in place.
For additional information on industrial security measures that may be implemented, please
visit:
https://www.siemens.com/industrialsecurity
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customer’s exposure to cyber
threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under

Due to the large number of possible applications, each detail of the described device versions
for each possible scenario during commissioning, operation, maintenance or operation in
systems cannot be considered in the instructions. If you need additional information not
covered by these instructions, contact your local Siemens office or company representative.
Note
Operation under special ambient conditions
We highly recommend that you contact your Siemens representative or our application
department before you operate the device under special ambient conditions as can be
encountered in nuclear power plants or when the device is used for research and development
purposes.
Safety notes
3.2 Requirements for special applications
SITRANS Probe LU240 with mA/HART
12 Compact Operating Instructions, 10/2018, A5E42673704-AB
Note
Operation under special atmospheric conditions
Ultrasonic measurement requires that the sound wave travel through the atmosphere in a
consistent manner. Applications with atmospheric conditions different from air (including, but
not limited to, gas layer stratification, very high methane or CO2 concentrations), should be
properly assessed to ensure safe, reliable use in the event of measurement errors due to sound
wave velocity changes.
3.3 Use in hazardous areas
Qualified personnel for hazardous area applications
Persons who install, connect, commission, operate, and service the device in a hazardous
area must have the following specific qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and systems
according to the safety regulations for electrical circuits, high pressures, aggressive, and
hazardous media.
● They are authorized, trained, or instructed in carrying out work on electrical circuits for
hazardous systems.
● They are trained or instructed in maintenance and use of appropriate safety equipment
according to the pertinent safety regulations.
WARNING
Use in hazardous area
Risk of explosion.
● Only use equipment that is approved for use in the intended hazardous area and labelled
accordingly.
● Don't use devices that have been operated outside the conditions specified for hazardous
areas. If you have used the device outside the conditions for hazardous areas permanently
make all Ex markings unrecognizable on the nameplate.

7. The equipment contains no user-replaceable parts and is not intended to be repaired by
the user. Repair of the equipment is to be carried out by the manufacturer, or their approved
agents, in accordance with the applicable code of practice.
8. Repair of this equipment shall be carried out in accordance with the applicable code of
practice.
9. If the equipment is likely to come into contact with aggressive substances, e.g. acidic liquids
or gases that may attack metals or solvents that may affect polymeric materials, then it is
the responsibility of the user to take suitable precautions that prevent it from being adversely
affected thus ensuring that the type of protection is not compromised.
10.The certificate number has an ‘X’ suffix which indicates that special conditions of installation
and use apply. Those installing or inspecting this equipment must have access to the
contents of the certificate or these instructions. The conditions listed in the certificate are
reproduced below:
– Under certain extreme circumstances, the non-metallic parts incorporated in the
enclosure of this equipment may generate an ignition-capable level of electrostatic
charge. Therefore the equipment shall not be installed in a location where the external
conditions are conducive to the build-up of electrostatic charge on such surfaces.
– In addition, the equipment shall only be cleaned with a damp cloth. This is particularly
important if the equipment is installed in a zone 0 location.

Quick commissioning wizard
The SITRANS Probe LU240 provides a single quick commissioning wizard that can be used
for various applications.
The initial wizard steps are common for all application types. Subsequent wizard parameters
will vary depending on the application you choose. For the purpose of documenting, three
separate lists follow. These lists include the wizard parameters available to commission each
application type (see links below).
1. From measurement view, press button to enter parameter view. The first level menu
(QUICK START) will display. Press button to enter this menu.
2. Press button again to enter "Quick commissioning wizard" (COMMISSION).
In the wizard, it is not necessary to press button to navigate to the next step. In each
step, you are taken directly to edit view.
3. Set "Operation", then "Material type".
Subsequent wizard parameters will vary depending on the application you choose. See
links below to step you through the wizard appropriate to your application.
4. Select "Yes" to confirm all parameter changes as the final step in the quick commissioning
wizard, and return to parameter view. "DONE" will appear on the main line of the display.
5. Press button three times to return to measurement view.
For more information about commissioning a Level, Space, Distance or Custom application,
go to Quick commissioning: Level/Space/Distance/Custom (Page 35).
For more information about commissioning a Volume application, go to Quick commissioning:
Volume (Page 40).
For more information about commissioning a Volume flow application, go to Quick

Note
Important information regarding the use of commissioning wizard
● A reset to factory defaults should be performed before running "Quick commissioning
wizard" if the device has been used in a previous application.
(Go to menu "Maintenance and diagnostics > Resets", and for parameter "Reset", select
setting "Factory reset".)
● Settings for quick commissioning wizard are inter-related and changes apply only after
"Confirm" is set to 'Yes' in final step.
● Do not use quick commissioning wizard to modify individual parameters. (See instead
chapter "Parameter assignment - Local" in full operating instructions.)
Perform customization for your application only
after
"Quick commissioning wizard" has
been completed.
Note
Wizard operation requires 22.5 mA
Device output will read 22.5 mA during wizard operation. When wizard completes, device
output will return to normal behavior.

HART communication 10
This device supports HART communication protocol.
SITRANS Probe LU240 can be configured over the HART network using the HART
Communicator 375/475 by Emerson, or a software package. The recommended software
package is the SIMATIC Process Device Manager (PDM) by Siemens.
Note
Supported HART parameters
For a list of applicable parameters, see the full operating instructions.
SIMATIC PDM
This software package is designed to permit easy configuration, monitoring, and
troubleshooting of HART devices. The HART EDD for SITRANS Probe LU240 was written with
SIMATIC PDM in mind and has been extensively tested with this software.
