Safety information
Please read this manual carefully, and also take
note of country-specific installation standards
(e.g. the VDE regulations in Germany) as well
as prevailing safety regulations and accident
prevention rules.
For safety and warranty reasons, any internal
work on the instruments, apart from that involved in normal installation and electrical connection, must be carried out only by qualified
VEGA personnel.

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.

1.2 Approvals
If measuring systems are installed according
to the following approvals, the respective
official documents must be consulted and
their regulations followed. The documents are
supplied with the respective measuring system.
WHG approval
VEGAMET 602 Ex signal conditioning instrument together with capacitive electrodes or
pressure transmitters as part of an overfill
protection system acc. to WHG.
To configure a measuring system, you need
a VEGAMET … signal conditioning instrument
and a sensor with analogue transmission of
measured values, e.g.
- capacitive electrodes or
Ex approval
For measuring system in hazardous areas,
certificate acc. to CENELEC.
