Safety

General safety information
The following safety section provides an overview of the
safety aspects that must be observed for operation of the
device.
The device is constructed in accordance with international
and local regulations and is deemed to be operationally safe.
Additionally, the device is tested and shipped from the
factory in working condition. The information contained
within this manual, as well as all applicable documentation
and certification, must be observed and adhered to in order
to maintain the factory-deployed condition throughout the
operations of the KM26 series system/solution.
Full compliance with the general safety requirements must be
observed during operation of the device. In addition to
providing general information, the individual sections within
this manual contain descriptions, processes and / or
procedural instructions with specific safety information for
that corresponding action.
Only by observing all of the safety information the user can
minimize the risk of hazards to personnel and / or the
environment. The provided instructions are intended as an
overview only and do not contain detailed information on all
available models or every conceivable scenario that may arise
during setup, operation and / or maintenance work.
For additional information, or in the event of specific issues
not covered within these operating instructions, please
contact the manufacturer. ABB declares the contents of this
manual are not part of any prior or existing agreements,
commitments or legal relationships and are not intended to
amend those that are already in place.
CAUTION
Only qualified and authorized personnel are to be tasked
with the installation, electrical connection, commissioning
and maintenance of the KM26 series MLG. Qualified
personnel are those individuals who have experience in
the installation, electrical connection, commissioning and
operation of the KM26 series MLG or similar devices /
systems and hold the necessary qualifications. These
qualifications include but are not limited to:
• training or instruction – authorization to operate and
maintain devices or systems according to safety
engineering standards for electrical circuits, high
pressures and aggressive media
• training or instruction in accordance with safety
engineering standards regarding maintenance and
use of adequate safety systems.
For reasons of safety, ABB recommends that only
sufficiently insulated tools, conforming to IEC EN 60900,
be used. Since the MLG may form a link within a safety
chain, it is recommended that the device be replaced
immediately if defects are detected. In the event of use in
a hazardous area, only non-sparking tools are to be used.
In addition, the user must observe all relevant safety
regulations regarding the installation and operation of
electromechanical systems and the relevant standards,
regulations and guidelines concerning explosion protection.
WARNING
The device can be operated at high levels of pressure and
with aggressive media. As a result, serious injury or
significant property damage may occur if this device is
operated incorrectly.
Improper use
The KM26 series MLGs are designed for reliable and accurate
measurement of liquid levels in the industrial applications.
Use the KM26 series MLG for this purpose only. The
manufacturer accepts no liability for any form of damage
resulting from improper use!
It is prohibited to use the device for the following but not
limited to these purposes:
• as a climbing aid (for example, for mounting purposes)
port for pipes.
• removing material (for example, by drilling any part of the
MLG
Technical limit values
The device is designed for use exclusively within the values
stated on the identification plates (Refer to section 4.1
identification) and within the technical limit values specified
on the data sheets.
The following technical limit values must be observed:
• the maximum working pressure must not be exceeded.
• the maximum ambient operating temperature must not
be exceeded.
