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.

Safety notes 2
2.1 Authorised personnel
All operations described in this documentation must be carried out only by trained
and authorized personnel.
During work on and with the device, the required personal protective equipment
must always be worn.
2.2 Appropriate use
SITRANS LR110 is a transmitter for continuous level measurement.
You can find detailed information about the area of application in chapter ""Product
description".
Operational reliability is ensured only if the transmitter is properly used according
to the specifications in the operating instructions manual as well as possible
supplementary instructions.
2.3 Warning about incorrect use
Inappropriate or incorrect use of this product can give rise to application-specific
hazards, e.g. vessel overfill through incorrect mounting or adjustment. Damage to
property and persons or environmental contamination can result. Also, the protective
characteristics of the transmitter can be impaired.
2.4 General safety instructions
This is a state-of-the-art transmitter complying with all prevailing regulations
and directives. The transmitter must only be operated in a technically flawless
and reliable condition. The operating company is responsible for the trouble-free
operation of the transmitter. When measuring aggressive or corrosive media that can
cause a dangerous situation if the transmitter malfunctions, the operating company
has to implement suitable measures to make sure the transmitter is functioning
properly.
The safety instructions in this operating instructions manual, the national installation
standards as well as the valid safety regulations and accident prevention rules must
be observed.

Safety notes
2.5Radar frequencies for worldwide use
For safety and warranty reasons, any invasive work on the device beyond that
described in the operating instructions manual may be carried out only by personnel
authorised by us. Arbitrary conversions or modifications are explicitly forbidden. For
safety reasons, only the accessory specified by us must be used.
To avoid any danger, the safety approval markings and safety tips on the device must
also be observed.
The low transmitting power of the radar transmitter is far below the internationally
approved limits. No health impairments are to be expected with intended use. The
band range of the measuring frequency can be found in chapter ""Technical data".
2.5 Radar frequencies for worldwide use
Country or region specific settings for the radar signals are determined via the
frequency. The operating mode must be set in the operating menu via Sitrans mobile
IQ App at the beginning of the setup.
WARNING
Operating the device without selecting the frequency for the appropriate country or
region group constitutes a violation of the regulations of the radio approvals of the
respective country or region.
2.6 Installation and operation in the USA and Canada
This information is only valid for USA and Canada. Hence the following text is only
available in the English language.
Installations in the US shall comply with the relevant requirements of the National
Electrical Code (NEC - NFPA70) (USA).
Installations in Canada shall comply with the relevant requirements of the Canadian
Electrical Code (CEC Part I) (Canada).
A Class 2 power supply unit has to be used for the installation in the USA and
Canada.
2.7 Security information
Siemens provides products and solutions with industrial security functions that
support the secure operation of plants, systems, machines and networks.
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.

Safety notes
2.7Security information
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 continous 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.

• Information about approvals
• Configuration information
• Technical data
• Serial number of the transmitter
• QR code for device identification
• Numerical code for Bluetooth access (optional)

3.2 Principle of operation
Application area
SITRANS LR110 is a radar transmitter for non-contact, continuous level
measurement. It is suitable for liquids and solids in practically all industries.
Functional principle
The transmitter emits a continuous, frequency-modulated radar signal through its
antenna. The emitted signal is reflected by the medium and received by the antenna
as an echo with modified frequency. The frequency change is proportional to the
distance and is converted into the level.
3.3 Adjustment
Wireless adjustment
Devices with integrated Bluetooth module can be adjusted wirelessly via
SiemensmobileIQapp.

3.4 Packaging, transport and storage
Packaging
Your transmitter was protected by packaging during transport. Its capacity to handle
normal loads during transport is assured by a test based on ISO4180.
The packaging consists of environment-friendly, recyclable cardboard. For special
versions, PE foam or PE foil is also used. Dispose of the packaging material via
specialised recycling companies.
Transport
Transport must be carried out in due consideration of the notes on the transport
packaging. Nonobservance of these instructions can cause damage to the device.
Transport inspection
The delivery must be checked for completeness and possible transit damage
immediately at receipt. Ascertained transit damage or concealed defects must be
appropriately dealt with.
Storage
Up to the time of installation, the packages must be left closed and stored according
to the orientation and storage markings on the outside.
Unless otherwise indicated, the packages must be stored only under the following
conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
