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
8VEGATOR 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.

A potentiometer for switching point adaptation is located on the front
plate of the signal conditioning instrument. With this potentiometer you
can adapt the measuring system to the conductivity of the product.
On top to the side (covered when mounted) there is a DIL switch block
with four switches. The individual switches are assigned as follows:
l 1 - A/B mode
- A - Max. detection or overflow protection
- B - Min. det
l 2 - Integration time 2 s

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.

If
a fault message is not wanted, a bridge must be provided on the

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
