2For your safety
2.1Authorised personnel
All operations described in this operating instructions manual
must be carried out only by trained specialist personnel
authorised by the operator.
During work on and with the device the required personal
protection equipment must always be worn.
2.2Appropriate use
VEGAKON 66 is a sensor for level detection.
You can find detailed information on the application range in
chapter "Product description".
2.3Warning 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.
2.4General 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 country-specific 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.
The user is also obliged to determine,during the entire
duration of use,the compliance of the necessary occupational
safety measures with the current valid regulations and take
note of new regulations.
2.5CE conformity
VEGAKON 66 is in CE conformity with EMC (89/336/EWG)
and LVD (73/23/EWG).
Conformity has been judged according to the following
standards:

lEMC:
-Emission EN 50081-1
-Susceptibility EN 50082-2
lLVD:EN 61010
2.6Environmental 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 man-
agement system is certified according to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the environ-
mental instructions in this manual:
lChapter "Packaging,transport and storage"
lChapter "Disposal"

3.2Principle of operation
The conductive VEGAKON 66 compact level switches detect
levels of conductive liquids.
If at least two electrodes are covered with a conductive
medium,small alternating currents (<1mA)flow from the
measuring electrode to the ground electrode.

Fig.2:Functional principle
1Ground probe
2Max.level (max.electrode)
3Min.level (min.electrode)
These alternating currents are measured in respect to their
amplitude and phase position and converted into a switching
command.
VEGAKON 66 can be used for reliable detection of products
over a very wide conductivity and viscosity range.
Alevel detection can be realised with two measuring electro-
des,e.g.a pump or two-point control with three measuring
electrodes.
VEGAKON 66 is a compact instrument,i.e.it can be operated
without external evaluation system.The integrated electronics
evaluates the level signal and outputs a switching signal.With
this switching signal,a connected device can be operated
directly (e.g.a warning system,aPLC,a pump etc.).
The data for power supply are stated in chapter "Technical
data"in the "Supplement".

3.3Operation
The VEGAKON 66 is a compact level switch with integrated
oscillator.
On the electronics module you will find the following indicating
and adjustment elements:
lControl lamp for indication of the switching condition
lMode changeover for selection of the output signal
lDIL switch for adjustment of the integration time
lRotary switch for adjustment of the conductivity value
3.4Storage and transport
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 environ-
ment-friendly,recyclable cardboard.In addition,the sensor is
provided with a protective cover of cardboard.For special
versions PE foam or PE foil is also used.Dispose of the
packaging material via specialised recycling companies.
lStorage and transport temperature see "Supplement -

4Mounting
4.1General instructions
Use the recommended cables (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGAKON 66 additional protection against
moisture penetration by leading the connection cable down-
ward in front of the cable entry.Rain and condensation water
can thus drain off.This applies mainly to mounting outdoors,in
areas where moisture is expected (e.g.by cleaning processes)
or on cooled or heated vessels.
Fig.3:Measures against moisture penetration
The process fitting must be sealed if there is gauge or low
pressure in the vessel.Before use,check if the seal material is
resistant against the measured product and the process
temperature.
The max.permissible pressure is stated in chapter "Technical
data"in the "Supplement"or on the type label of the sensor.
4.2Mounting information
Due to agitators,equipment vibration or similar,the probe can
be subjected to strong lateral forces.
During operation,the probe must not touch any installations or
the vessel wall.If necessary,secure the end of the probe
(insulated). Provide a suitable insulated support directly above
the probe end.
