3.2 Principle of operation
VEGATOR 631 Ex is a single signal conditioning instrument for
processing the signals of conductive probes.
The VEGATOR 631 Ex signal conditioning instrument powers
connected sensors and simultaneously processes their measuring
signals.
When the medium reaches the switching point of the sensor, the
voltage between sensor and VEGATOR 631 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 integration time and the mode (A/B) can be preset via a DIL switch
block on the signal conditioning instrument.
A potentiometer for adjustment the switching point is located on the
front panel of VEGATOR 631 Ex.

Storage
8 VEGATOR 63
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.
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.

To implement line monitoring, you ha
ve to mount a resistor of 220 kΩ
between terminals 1 and 2 in the connection housing of the probe. This
means that with single point control, the measuring and ground
electrode are monitored and with two-point control, the max. and
ground electrode.
When a fault message is generated, the switching output is
simultaneously activated.

Note:
Keep in mind
momenet when the switching point is reached and the momenet when
the switching function is triggered, there is an integration time of
0.5 sec. The potentionmeter must therefore be turned slowly.
A possible additional integration time should only be switched on after
the adjustment.
In all following applications in conjunction with an integrated resistor of

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 and output signals.
The procedure is described as follows. In many cases the causes can
be determined this way and faults can be easily 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.

8.2 Disposal
The instrument consists of materials which can be recycled by
specialised recycling companies. We use recyclable materials and
have designed the electronics to be easily separable.
WEEE directive 2002/96/EG
This instrument is not subject to the WEEE directive 2002/96/EG and
the respective national laws. Pass the instrument directly on to a
specialised recycling company and do not use the municipal collecting
points. These may be used only for privately used products according
to the WEEE directive.
Correct disposal avoids negative effects to persons and environment
and ensures recycling of useful raw materials.
