2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the
appropriate instrument has been selected in terms of measuring range,
design and specic measuring conditions.
Serious injuries and/or damage can occur should these not be observed.
Further important safety instructions can be found in the individual chapters
of these operating instructions.
2.1 Intended use
The model LSO.06 transducer is used for limit value detection in liquids. The
model LSO.25 switching amplier may be used in conjunction with the model LSO.06
transducer for overow control. The instruments are very robust and designed for rough
operating conditions.
These instruments have been designed and built solely for the intended use described
here, and may only be used accordingly.
The technical specications contained in these operating instructions must be observed.
Improper handling or operation of the transducer and the switching amplier outside of its
technical specications requires the instrument to be shut down immediately and inspect-
ed by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.

2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to
equipment.
■
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualications described
below.
■
Keep unqualied personnel away from hazardous areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and
knowledge of country-specic regulations, current standards and directives, are capable
of carrying out the work described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.
2.3 Additional safety instructions for instruments with ATEX approval
WARNING!
■
Non-observance of these instructions and their contents may result in the
loss of explosion protection
■
Observe the European Use Directive (EN 60 079-10:1996 )
2.4 Special hazards
WARNING!
Observe the information given in the applicable type examination certicate
and the relevant country-specic regulations for installation and use
in potentially explosive atmospheres (e.g. IEC 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to equipment.
For additional important safety instructions for insturments with ATEX
approval see chapter "2.3 Additional safety instructions for instruments with
ATEX approval".

WARNING!
To ensure safe working on the instrument, the operating company must
ensure
■
that suitable rst-aid equipment is available and aid is provided whenever
required.
■
that the operating personnel are regularly instructed in all topics regarding
work safety, rst aid and environmental protection and knows the
operating instructions and, in particular, the safety instructions contained
therein.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
Electrical instruments may only be installed and mounted by skilled
electrical personnel.
■

4.1 Description
The transducer is used for measuring liquid level limits.
The conical tip of the sensor ensures really precise on-off performance level sensing.
Its reaction is independent of various physical parameters of the liquid such as density,
dielectric constant, conductivity, colour or refractive index. This allows the use for safe
level switching as well as for precise level control applications. If there is any foam you
even can decide whether to use the sensor for foam level or liquid level control, suppress-
ing the influence of foam on switching.
If the sensor is supplied with a U-tip, it is able to sense changes in refractive index. So it
can be used for example as an interface level switch for liquids.

4.2 Instrument design
Each unit consists of a transducer and a controller (switch amplier). The transducer may
be of one-piece or multi-part design. Ex types are generally constructed as multi-part
types. Multi-part transducers can be equipped with a heat-sink to expand the temperature
range.

For explosion protected version please note the following :
The amplier is designed as a plug-in card for a 19" plug-in card. The plug-in card alone
doesn't fulll the ingress protection IP 20 in accordance with EN 60529: 1991. It only is
intended for the installation into a suitable rack which guarantees the minimum ingress
protection IP 20. Not used plug-in places have if necessary to be covered with blind plates.
The distances and tracking distances particularly are between the individual plug-in cards
as well as the intrinsic safe and not intrinsic safe circuits, the requirements on the wiring as
well as the excess temperature and the dissipation power converted in the assemblies are
to take into account according to
EN 60079-11:2007 . To avoid mistakes, the switch ampli-
ers are provided with an encoding system. It has to be made sure that the counter-strip is
executed availably and identically in the 19" rack.

5. Transport, packaging and storage
5.1 Transport
Check instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -25 ... +70 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
Avoidance of exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, ammable atmospheres
Store the instrument in its original packaging in a location that fullls the conditions listed
above. If the original packaging is not available, package and store the instrument as
described below:
1. Wrap the instrument in an antistatic plastic lm.
2. Place the instrument, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag, containing a
desiccant, inside the packaging.
WARNING!
Before storing the instrument (following operation), remove any residual
media. This is of particular importance if the medium is hazardous to health,
e.g. caustic, toxic, carcinogenic, radioactive, etc.
