3.2Principle 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".
3.3Operation
The integration time and the mode (A/B)can be preset via a DIL switch
block on the signal conditioning instrument.
Apotentiometer for adjustment the switching point is located on the
front panel of VEGATOR 631 Ex.
3.4Packaging,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 environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
