3.2 Principle of operation
VEGATOR 532 Ex is a single signal conditioning instrument with two
channels for processing the signals of conductive probes.
oning instrument 7
3 Product description
Functional principle
Power supply
Packaging
Transport
The VEGATOR 53
2 Ex signal conditioning instrument powers
connected instruments and simultaneously processes their measuring
signals.
When the medium reaches the switching point of the sensor, the
voltage between sensor and VEGATOR 532 Ex drops. The output
relays then switch according to the set mode.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3 Operation
The mode (A/B) can be preset via the DIL sw itch on the signal
conditioning instrument.
A potentiometer for switch point adjustment is located on the front
plate of VEGATOR 532 Ex.
3.4 Packaging, transport and storage
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 f oam 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.
Transport inspection
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.
Storage
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:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration

When you are mounting VEGATO
R 532 Ex with Ex approval in a carrier,
you have to use a VEGA Ex module.
In Ex applications, a protection of IP 20 must be maintained. Cover the
gaps or free modules from the front with appropriate blind covers.
Keep a distance of at least 2 TE (10 mm/0.4 in) from the module cards
of other manufacturers.
If you want to mount VEGATOR 532 Ex in the complete left position in
the carrier, you have to mount a blind cover with at least 4 TE (20 mm/
0.8 in) in front of the module of VEGATOR 532 Ex.

The Ex separating chamber must be plugged in before starting with the
setup of the Ex versions of VEGATOR 532 Ex.
The Ex separating chamber is part of module 33/Ex-33.
Safe operation can be only ensured if the operating instructions
manual and the EU type approval certificate are observed. VEGATOR
532 Ex must not be opened.
You can find further information on mounting the Ex separating
chamber in the operating instructions manual of the module (module
33/Ex-33).
Instrument coding

VEGATOR 532 Ex • Signal conditi
All signal conditioning instruments are provided with different gaps
dependent on type and version (mechanical coding).
The module is provided with coded pins that can be inserted to prevent
accidental interchanging of the various instrument types.
The coded pins are part of module 33/Ex-33.
With a VEGATOR 532 Ex in Ex version, the supplied coded pins (type
coded pins and Ex coded pin) must be inserted by the user according
to the below chart.

Two potentiometers for switching point adaptation are located on the

medium separately for each channel.
Use a small screwdriver to carry out adjustments on the potentiometer.
One slide switch per channel is located on the circuit board of the

To monitor the electrodes and their circuits, a resistor of 220 kΩ must
be mounted between connection 1 and connection 2 in the connection
housing of the probe, i.e. with single point control, the measuring and
earth electrodes are monitored, and with double point control, the max.
and earth electrodes are monitored.
If you want to use both channels for two separate measurements (no
two-point control), the measuring electrodes are monitored, e.g.
ground and max. electrode of channel 1 (connection d30 and d32) and
ground and min. electrode of channel 2 (connection z30 and z32).
By doing this, a failure is triggered separately for each channel. In case
of failure:
l the channel-specific control lamp fault signal lights
l the relay output of the concerned channel deenergises
l the transistor output of the concerned channel is blocked
l The functions of the inteferred channel remain
For probes with 220 kΩ resistor, a soldering bridge must be closed on

The max. electrode is now adapted to the conductivity of the medium,
i.e. the relay (channel 1) deenergises at max. level and the transistor

Prerequirements
l First of all, connect only ground and max. electrode to the signal
conditioning instrument (terminals d28 and d30)
l Set the selection switch to mode A
l Connect the signal conditioning instrument to power supply
l Turn the potentiometer (channel 1) to position 0
l Fill the vessel until the max. electrode is covered approx. 1 cm by

l Connect the min. electrode to terminal d32 of the signal
conditioning instrument
The two-point control is now adapted to the conductivity of the
medium, i.e. the relay deenergises at max. level and the transistor
blocks.
This switching condition remains until the level falls below the position
of the min. electrode, i.e. the relay energizes at min. level and the
transistor conducts.
The relay deenergises again at max. level and the transistor blocks.

7.2 Remove interferences
A maximum of reliability is ensured. Nevertheless, faults can occur
during operation. These may be caused by the following, e.g.:
l Measured value from sensor not correct
l Power supply
l Interference on the cables
The first measure to be taken is to check the input/output signal. In
many cases, the causes can be determined this way and the faults
rectified.
However, should these measures not be successful, call the VEGA
service hotline in urgent cases under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.
