When the annular electrode is covered with a conductive medium,
small alternating currents (<1mA)flow from the measuring electrode
to the reference and neutralisation electrode.

4insulation
These alternating currents are measured in respect to their amplitude
and phase position and converted into a switching command.
Interfering buildup is automatically eliminated via the neutralisation
electrode,the conductivity detected and the switching point sensitivity
derived thereof.An adjustment of the instrument is not necessary.
VEGAKON 61 can be used for reliable detection of products over a
very wide conductivity and viscosity range.
VEGAKON 61 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,a
PLC,a pump etc.).
The data for power supply are specified in chapter "Technical data".
3.3Operation
The VEGAKON 61 is a compact level switch with integrated
electronics module.
On the electronics module you will find the following indicating and
adjustment elements:
lControl lamp for indication of the switching status
lMode changeover for selection of the output signal

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 environment-
friendly,recyclable cardboard.In addition,the sensor is provided with
a protective cover of paperboard.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.
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.
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:
lNot in the open
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration
lStorage and transport temperature see chapter "Supplement -
Technical data -Ambient conditions"
lRelative humidity 20 …85 %

4Mounting
4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,process seal and process fitting,are
suitable for the existing process conditions.These include above all
the process pressure,process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data"or on the
type label.
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your VEGAKON 61 additional protection against
moisture penetration by leading the connection cable downward in
front of the cable entry.For this reason,the housing can be turned
without any tools by 270°.Rain and condensation water can thus drain
off.This applies mainly to outdoor mounting as well as installation in
areas where high humidity is expected (e.g.through 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 specified in chapter "Technical data"
or on the type label of the sensor.
4.2Mounting instructions
Remove the supplied seal from the thread of VEGAKON 61.This seal
is not required when using the welded socket with O-ring in front.
