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.

2Neutralisation electrode
3Probe
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.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
Connect the operating voltage according to the following connection
diagrams.The electronics module KONE60Ris designed in protection
class 1.To maintain this protection class,it is absolutely necessary
that the ground conductor be connected to the internal ground
terminal.Take note of the general installation regulations.
The data for power supply are specified in chapter "Technical data".
The instrument is connected with standard two-wire cable without
screen.If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas,screened cable should be
used.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
5.2Connection instructions
Danger:
Switch offpower supply before starting connection work.
Connect mains voltage according to the connection diagrams.

7Maintenance and fault rectification
7.1Maintenance
When used as directed in normal operation,VEGAKON 61 is
completely maintenance free.
7.2Electronics exchange
In general,all electronics modules of series KONE60 can be
interchanged.If you want to use an electronics module with a different
signal output,you can download the corresponding operating
instructions manual from our homepage under Downloads.
Proceed as follows:
1Switch offpower supply
2Unscrew the housing cover
3Loosen compression fittings with a screwdriver
4Pull the connection cables out of the terminals
5Loosen the two screws with a screw driver (Phillips recessed
head)
6Pull out the old electronics module
7Compare the new electronics module with the old one.The type
label of the electronics module must correspond to that of the old
electronics module.
8Note settings of all adjustment elements of the old electronics
module.
Set the adjustment elements of the new electronics module to the
same settings of the old one.
9Screw in and tighten the two holding screws with a screwdriver
(Phillips)
10 Insert the wire ends into the open terminals according to the wiring
plan
11 Tighten the screw terminals
12 Check the hold of the wires in the terminals by lightly pulling on
them
13 Check cable gland on tightness.The seal ring must completely
encircle the cable.
14 Screw the housing cover on
The electronics exchange is now finished.
As soon as you insert the electronics module,VEGAKON 61 is ready
for operation.
