2.1 Authorised personnel
All operations described in this operating instructions manual must be
carried out only by trained specialist personnel authorised by the plant
operator.
During work on and with the device the required personal protective
equipment must always be worn.
2.2 Appropriate use
The EL 6 is a sensor for level detection.
You can find detailed information on the application range in chapter
"Product description".
Operational reliability is ensured only if the instrument is properly used
according to the specifications in the operating instructions manual as
well as possible supplementary instructions.
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 the manufacturer. Arbitrary
conversions or modifications are explicitly forbidden.
2.3 Warning about misuse
Inappropriate or incorrect use of the instrument can give rise to
application-specific hazards, e.g. vessel overfill or damage to system
components through incorrect mounting or adjustment.
2.4 General safety instructions
This is a high-tech instrument requiring the strict observance of
standard regulations and guidelines. The user must take note of the
safety instructions in this operating instructions manual, the countryspecific installation standards as well as all prevailing safety
regulations and accident prevention rules.
The instrument must only be operated in a technically flawless and
reliable condition. The operator is responsible for trouble-free
operation of the instrument.
During the entire duration of use, the user is obliged to determine the
compliance of the required occupational safety measures with the
current valid rules and regulations and also take note of new
regulations.

2.6 Environmental instructions
Protection of the environment is one of our most important duties. That
is why we have introduced an environment management system with
the goal of continuously improving company environmental protection.
The environment management system is certified according to DIN
EN ISO 14001.
Please help us fulfil this obligation by observing the environmental
instructions in this manual:

Application area
Functional principle
Voltage supply
3.2 Princi
EL 6 is a point level sensor with partly insulated conductive electrode
for level detection.
EL 6 is very rugged and can be used in all areas of industrial process
technology.
The level switch can be used in conductive liquids such as e.g. water.
Typical applications are overfill and dry run protection.
The conductive measuring principle places no special requirements on
installation. Hence, many different applications can be equipped with
EL 6.
Conductive probes detect the product resistance when their electro-
des are covered by the product.
The switching signal is determined by the length or mounting position
of the respective electrode.
A low alternating current flows through the electodes, is measured for
amplitude and phase position by the electronics of the signal
conditioning instrument and converted into a switching command.
EL 6 is operated with an external processing unit. The connected
signal conditioning instrument powers EL 6 and provides a switching
signal. A connected device can be activated directly with this switching
command (e.g. a warning sys tem, a PLC, a pump, etc.).
You can find the exact range of the voltage supply in chapter
"Technical data" in the operating instructions manual of the signal
conditioning instrument.

3.3 Operation
The probe does not have its own electronics. The measurement is
carried out via the connected signal conditioning instrument.
3.4 Storage and transport
Packaging
Transport
8 Cond
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
