3.2 Principle of operation
Application area
35243-EN-120228
VEGATOR 632 • Signal conditioning instrument 7
VEGATOR 632 is a single signal conditioning instrument with two
channels (relay) for processing the signals of conductive probes.
3 Product description
Functional principle
The following switching functions are possible:
l Single channel control (simple level detection)
l Two-point control (pump control)
l Two-channel control (two separate switching points)
l Four-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.

Transport
Transport inspection
Detailed information about the power supp ly can be found in chapter
"Technical data".
3.3 Operation
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.
3.4 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 foam or PE foil
is also us ed. 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.

cable
Cable screening and
grounding
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
l If overvoltage surges are expected, overvoltage arresters should
be installed
Tip:
We recommend VEGA overvoltage arresters B61-300 (power supply
VEGATOR 632) and B62-36G (sensor supply).
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
The power supply can be 85 … 253 V AC, 50/60 Hz or 20 … 60 V DC.
The operating voltage of VEGATOR 632 is connected with standard
cable according to the national installation standards. The line
resistance must be max. 25 Ω per wire. If electromagnetic interference
is expected which is above the test values of EN 61326 for industrial
areas, screened cable should be used.
If screened cable is necessary, connect the cable screen on both ends
to ground potential. In the sensor, the screen must be connected
directly to the internal ground terminal. The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed, but the protective effect against high frequency interference si gnals remains.

connected to the ground terminal of VEGATOR 632.
Line monitoring
35243-EN-120228
VEGATOR 632 • Signal conditioning instrument 13
The line break monitoring or alarm function defines the function of the
signal conditioning instrument in case of failure.
The line monitoring is required for probes with approval according to
WHG (WRA) or Ex.
To realize a line monitoring, an additional electronics must be
integrated in the connection housing of the probe.

Note:
When carrying out switching point adjustments keep in mind that there
is a switching delay of 0.5 sec between the moment when the
switching point is reached and the moment when the switching
function is triggered. The potentiometer must therefore be turned
slowly.
A possible additional switching delay should only be switched on after
the adjustment.
Signal lamps (C)
Control lamps (LED) in the front plate indicate operation, switching
status and fault signal.

- Mains voltage on, instrument is operating
l Red (rd)
- Failure lamp
- Fault on the sensor circuit due to sensor failure or line break
- If the fail safe relay is deenergized, the red failure lamp will
light
l Yellow (ye)
- Relay control lamps
- The yellow relay control lamps react depending on the set
mode (min./max.)
- The relay control lamp generally indicates the activated

switching point is reached and the moment when the switching
function is triggered. The potentiometer must therefore be turned
slowly.
A possible additional switching delay should only be switched on after
the adjustment.
The following switching delays can be selected with the 3-step switch.

10.6 Master/Slave function
Definition of the instru-
ment as Master or Slave
(DIL switch block A)
When connecting two VEGATOR 632 signal conditioning instruments,
one instrument must be configured as reference power supply unit
(Master) and one as Slave.
Adjust the respective instrument as Master or Slave with switch 8 of
the DIL switch block (A).
To ensure that the two VEGATOR 632 can synchronize their phases, a
connection cable is required between the two signal conditioning
instruments.
Connect this connection cable according to the following illustration
between terminals 10 of the signal conditioning instruments.

Malfunction
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 Voltage 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.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline 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.
? The red failure control lamp (LED) of the signal conditioning
instrument lights
l Sensor not connected correctly
à Check the electrical connection by means of the wiring plans
l Line break
à Check the electrical connection cables from the probe to the
signal conditioning instrument
l Probe without line break monitoring
à Check if in the sensor housing between terminals 1 and 2 the
electronics for line break monitoring is mounted. If the probe
has no line break monitoring, set the switch for line break
monitoring (alarm) on the signal conditioning instrument to off.
In Ex systems, make sure that the Ex protection is not compromised by
the possible use of measuring instruments.
? The signal conditioning instrument does not switch when the
respective probe is covered or uncovered
l Operating voltage missing (green control lamp is off)
