35243-EN-120228

The following switching functions are possible:
lSingle channel control (simple level detection)
lTwo-point control (pump control)
lTwo-channel control (two separate switching points)
lFour-channel control or combination of two-point and two-channel
control (with two VEGATOR 632)
The VEGATOR 632 signal conditioning instrument powers connected
sensors and simultaneously processes their measuring signals.
It delivers a small alternating current to the measuring cell via the
signal cable.Electrolytic decomposition of the electrode rods and the
medium is avoided by using alternating current.
The cable is connected to the measurement loop or the metallic vessel
and the probe.
When the medium reaches the switching point of the sensor,the
voltage on the sensor 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 damping and the mode can be adjusted on the signal conditioning
instrument via the slide switch.The instrument function can be
preadjusted with a DIL switch block.
The switching point can be adjusted with a potentiometer.
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.
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.
