3.2 Principle 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 (<1 mA) flow from the
measuring electrode to the ground electrode.
1
3
2
Fig. 2: Functional principle
1 Ground probe
2 Max. level (max. electrode)
3 Min. 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.
A level detection can be realised with two measuring electrodes, 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, a PLC, a pump etc.).
The data for power supply are stated in chapter "Technical
data" in the "Supplement".

4 Mounting
4.1 General 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 downward 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.
4.2 Mounting 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.

5 Connecting to power supply
5.1 Preparin
g the connection
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
Connect
the power supply according to the following diagrams.
Oscillator KONE60R is 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. As a
rule, connect VEGAKON 66 to vessel ground (PA), or in case
of plastic vessels, to the next ground potential. On the side of
the housing there is a ground terminal between the cable
entries. This connection serves to drain off electrostatic
charges.
The data for power supply are stated in chapter "Technical
data" in the "Supplement".
VEGAKON 66 is connected with standard cable with round
cross section. An outer cable diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland.
If cable with a different diameter or wire cross section is used,
exchange the seal or use an appropriate cable connection.
5.2 Connection instructions
Danger:
Switch off power supply before starting connection work.
Connect mains voltage according to the connection diagrams.
5.3 Wiring plan
Is used to switch external voltage sources to relays,
contactors, magnetic valves, horns etc.

With the rotary switch you can set the sensitivity of the
instrument. Position 0.1 kΩ is the less sensitive and switch
position 300 kΩ the most sensitive one, see chart "Switching
point adjustment".
There are three switches on the DIL switch block by which you
can adjust the switching on and off delay. Thus prevents, e.g.
the instrument from permanent switching if the level is within
the limits.
The delay refers to the switching status of both relay outputs.
With the switches (2 s, 6 s, 12 s) you can set the integration
time respectively in the range of 0 to 20 seconds. The times of
the activated timers add up. If e.g. the switches 2 s and 12 s
are activated, the integration time will be 14 s.
With the mode adjustment (A/B) you can change the switching
condition of the output. You can set the required mode
according to the "Function chart" (A - max. detection or overfill
protection, B - min. detection or dry run protection).
Loosen the holding screws of the electronics module. Fold the
tensile proving ring upward. With the tensile proving ring you
can pul the electronics module out of the instrument housing.

In case of horizontally mounted instruments, the response
height is determined by the mounting height.
In case of vertically mounted instruments, the response height
is determined by the length of the probe rods.
The modification of the response height by turning the
conductivity value switch is not useful.
To adapt the response height, you can shorten the measuring
rods by sawing them off. Before shortening, unscrew the rods
out of the plastic threaded part of the sensor to avoid
damaging the probe.
The numbers of the rods are visible on the lower side of the
thread.
The ground rod (no. 1) must have the same length or must
even be longer than the longest of the other rods.
The max. rod (no. 2) defines the response height with single
point level switches or the upper switching level with two-point
control. It is the shortest rod.
The min. rod (no. 3) defines the lower switching level, it must
hence be longer than the max. rod. It is not available with
instruments for single point level detection.
The electronics recognises if a min. rod is screwed in and
changes automatically from single to two-point control.
For products with a good conductivity (>3 mS), set the rotary
switch - cnductivity setting (3) generally to switch position 3 kΩ.
Hence the instrument is already completely adjusted.
Take note of the instructions in chart "Examples of conductivity
values". The recommended settings take also influences such
as e.g. condensation or slight buildup into account.

If there is danger of strong buildup or condensation, you can
set the instrument more insensitive by one rotary switch
position.
The "Function chart" shows how to select the switching
condition of the output.
The following settings apply to products with low conductivity
(<3 mS)
1 Fill the vessel until the shortest probe is covered approx.
1 cm
2 Switch on voltage supply
3 Set the A/B switch to mode A
4 Set the rotary switch to position "TEST min."
5 Turn the rotary switch slowly clockwise until the red LED
lights
The instrument is adapted to the medium, i.e. the relay
denergizes with max. level.
The following settings apply to products with low conductivity
(<3 mS)
1 Empty the vessel until the min. measuring electrode is only
covered approx. 1 cm
2 Switch on voltage supply
3 Set the A/B switch to mode B
4 Set the rotary switch to position "TEST max."
5 Turn the rotary switch slowly anticlockwise until the red
LED lights
The instrument is adapted to the medium, i.e. the relay
deenergized with min. level.
The following settings apply to products with low conductivity
(<3 mS)
1 Fill the vessel until the shortest probe is covered approx.

The instrument is adapted to the medium, i.e, the relay
deenergizes when the max. level is reached. Only when the
min. probe is decreased, the relay energizes again.
Example: A filling pump is switched on when the min. signal is
decreased, fills the vessels until max. signal is reached and is
then switched off.
The following settings apply to products with low conductivity
(<3 mS)
1 Empty the vessel until the min. measuring electrode is only
covered approx. 1 cm
2 Switch on voltage supply
3 Set the A/B switch to mode B
4 Set the rotary switch to position "TEST max."
5 Turn the rotary switch slowly anticlockwise until the red
LED lights
The instrument is adapted to the medium, i.e. the relay
energizes at max. level. Only of the min. probe is decreased,
the relay denergizes again.
Example: An emptying pump is switched on when the max.
signal is reached, empties the vessels until min. signal is
reached and is then switched off.
In case of several measurement loops (same medium), the
adjustment of one instrument with medium is sufficient. The
determined switch position can be transferred to all other
instruments.
When the conductivity value is known, the switching point
adjustment can be carried out according to the setup in chart
"Rotary switch adjustment".
When exchanging the electronics module, it is sufficient to take
over the setting of the old electronics module.
