VEGATOR 3
Product description
1 Product description
1.1 Function and configuration
VEGATOR 521, 522, 523 and 527 level
switches are signal conditioning instruments
in European size (DIN 41 494) for level
detection. Typical applications are overfill
protection in vessels and dry run protection
or double point control of pumps. Depending
on the instrument type, up to 2 sensors with
analogue transmission of measured data can
be connected to the input. 2 relays (spdt)
and 2 floating transistors are available as
outputs. All instruments are equipped with a
fail-safe relay and transistor. The instruments
are provided with fault monitoring and
adjustable integration time.
All VEGATORs are available with Ex
approvals or as overfill protection systems
acc. to WHG and VbF.
Function
VEGATOR signal conditioning instruments
enable detection of min./max. levels. The
measured data of the sensor are converted
into a switching command, and connected
instruments can be switched on or switched
off. The integrated fault monitoring detects
short-circuit or break of the measuring cable
as well as selected failures from the
transmitter. The failure lamp lights and the
output relays and output transistors are
deenergised in case of failure.
In case of mains failure, the relays
deenergise.
Configuration
For configuration of a measuring system, a
VEGATOR and one or two sensors with
analogue measured data transmission, e.g. a
capacitive electrode or a pressure
transmitter are required.
