1.1 Function and configuration
Product description
VEGAMET 601 and 602 signal conditioning
instruments are modulare units with plug-in
sockets suitable for carrier rail mounting
(DIN 46 277). Together with the respective
sensors they are used for continuous level
measurement.
The evaluation results are made available as
a current output 0/4 … 20 mA and a voltage
output 0 … 10 V. The instruments are
equipped with an adjustable integration time,
and in addition VEGAMET 602 Ex has a fault
monitoring.
Function
The measuring data of the sensor are
outputted as level-proportional current and
voltage signals. The adjustment (empty and
full adjustment) can be done very easily via
two potentiometers.
Fault monitoring on VEGAMET 602
The integrated fault monitoring on VEGAMET
602 detects shortcircuit and line break of the
measuring cable. A failure LED lights in case
of failure and a failure relay deenergises.

2 Mounting and installation instructions
Mounting and installation instructions
Mounting
Each series 600 signal conditioning instrument consists of a plug-in socket for carrier
rail mounting DIN 46 277 and a module unit.
The supply voltage can be connected to
terminals 9 and 10.
For neighbouring series 600 signal conditioning instruments it is possible to continue
the connection L1 and N directly via the supplied plug-in jumpers.
The same is valid for the connection of VEGAMET voltage output 0 … 10 V to VEGASEL
voltage input 0 … 10 V, terminals 7 and 8).
Note!
It is not allowed to use the jumpers for single
instruments or at the respective end of an
instrument row. If this instruction is not observed, there is the danger of contacting the
operating voltage or causing a short-circuit.
As a rule, the signal conditioning instrument
must be mounted outside the hazardous
area or special Ex protective measures must
be taken.
Transparent cover
To protect the instrument against unauthorised or inadvertent use, the front plate of
VEGAMET can be provided with a sealable
transparent cover after setup. To remove the
transparent cover see the following figure.
10 VEGAMET 601, 602
Mounting and installation instructions
Coding
To avoid mixing up the various signal conditioning instruments, the plug-in socket is
provided with pins and the signal conditioning instrument with appropriate gaps
(mechanical coding).
Instrument coding ensures (with differently
positioned coded pins) that the various signal conditioning instruments are not inadvertently swapped.
An Ex coding with fixed coded pin ensures
that non-Ex and Ex instruments are not interchanged.
The coding is part of the explosion protection: on VEGAMET 602 Ex the supplied
coded pins (instrument coded pin and Ex
coded pin) must be inserted by the operator
acc. to the table below.

3 Electrical connection
Electrical connection
3.1 Connection instructions
The following wiring plans are valid for standard as well as Ex versions of the signal conditioning instruments. Please observe the
following instructions:
- the relay contact of VEGAMET 602 Ex is
shown in a de-energised condition
- if strong electromagnetic interferences are
expected, we recommend the use of
screened signal cables
- the screening must be earthed only on one
side (sensor side)
- in case of overvoltages, we recommend
the use of VEGA overvoltage arresters
- the connection must be made acc. to the
respective national installation standards
(e.g. in Germany acc. to the VDE regulations).
3.2 Connection instructions for approved applications
The following applications require the use of
certified instruments:
- in hazardous areas (if necessary, observe
special national regulations)
- as part of an overfill protection system acc.
to WHG
- in the shipbuilding industry
- in pressurised vessels.
For these applications, the respective official
documents (test reports, test certificates,
general type approval, type approval certificate and conformity certificates) as well as
the valid installation and operating regulations
must be noted. The official documents are
supplied with the respective instrument.
In Ex applications, the voltage supply of the
sensor must only be made via an intrinsically
safe circuit. These are the possibilities:
- VEGAMET series 600 signal conditioning
instrument in Ex version
- not certified VEGAMET series 600 signal
conditioning instrument with VEGA safety
barrier type 145
The official documents of these additional
instruments must also be noted.

With the upper three DIL switches you can
set an integration time. If all three are set to
position "off", the integration time is zero seconds. With switch "2" two seconds are set,
with switch "6" six seconds are set, etc. If
several switches are set to "on", the time
intervals will be summed up. It is therefore
possible to set 2, 6, 8,12, 18 or 20 seconds
as integration time.
With the fourth DIL switch you choose if you
want to have a 4 … 20 mA or a 0 … 20 mA
current output.
4.2 Setup sequence
The following list gives you a short descrip-
tion of the setup steps
- mount the plug-in socket
- wire the plug-in socket acc. to your control
requirements
- cover the input terminals with the separating wall (4)
- set the range of the current output on the
DIL switch (11)
- set the integration time on the DIL switch
(11) to "off"
- now mount the module unit into the plug-in
socket
- switch on the power supply, the green LED
(3) lights
- carry out the adjustment acc. to "Section
4.3"
- if an integration time is necessary, the instrument must be removed again and the
respective setting must be made on the
DIL switch.
4.3 Adjustment
The adjustment of the empty and full levels is
made via two spindle potentiometers. For the
adjustment procedure, it is useful to connect
a voltmeter to the voltage output 0 … 10 V.
This means:
- empty adjustment, vessel empty corresponds to 0.0 Volt or level 0 %
- full adjustment, vessel full corresponds to
10.0 Volt or level 100 %
Note the following adjustment examples. As a
rule, the potentiometer 1 must first be turned
approx. 22 revolutions clockwise before the
empty and full adjustment is carried out.
As an additional aid to adjustment, the lowest
segment of the analogue display flashes at
0.0 V and the highest at 10.0 V.

If the failure lamp continues to light, the signal conditioning instrument
is defective. In this case, send the instrument for repair to VEGA.
- Should the failure lamp extinguish, connect the signal conditioning

connect instead a resistor of 2.2 kOhm.
- If the failure lamp continues to light, probably the connection cable is
