2 For your safety
2.1 Authorised personnel
All operations described in this operating instructions manual
must be carried out only by trained specialist personnel
authorised by the operator. For safety and warranty reasons,
any internal work on the instruments must be carried out only
by personnel authorised by the manufacturer.
2.2 Appropriate use
VEGASON 66 is a sensor for continuous level measurement.
Detailed information on the application range of VEGASON 66
is available in chapter "Product description".
2.3 Warning about misuse
Inappropriate or incorrect use of the instrument can give rise to
application-specific hazards, e.g. vessel overfill or damage to
system components through incorrect mounting or adjustment.
2.4 General safety instructions
VEGASON 66 is a high-tech instrument requiring the strict
observance of standard regulations and guidelines. The user
must take note of the safety instructions in this operating
instructions manual, the country-specific installation standards
(e.g. the VDE regulations in Germany) as well as all prevailing
safety regulations and accident prevention rules.
2.5 CE conformity
VEGASON 66 is in CE conformity with EMC (89/336/EWG)
and to NSR (73/23/EWG).
Conformity has been judged according to the following
standards:
l EMC:
- Emission EN 61326: 1997 (class A)
- Susceptibility EN 61326: 1997/A1:1998
l LVD: EN 61010-1: 2001
VEGASON 66 is designed for use in an industrial environment.
Nevertheless, electromagnetic interference from electrical
conductors and radiated emissions must be taken into
VEGASON 66 - 4 ... 20 mA/HART - four-wire 5
For your safety
28783-EN-060731
account, as is usual with a class A instrument acc. to
EN 61326. If VEGASON 66 is used in a different environment,
the electromagnetic compatibility to other instruments must be
ensured by suitable measures.
2.6 Fulfilling NAMUR recommendations
In respect to interference resistance and emitted interference,
VEGASON 66 fulfils NAMUR recommendation NE 21.
VEGASON 66 and its indicating/adjustment components fulfill
NAMUR recommendation NE 53 in respect to compatibility.
VEGA instruments are generally upward and downward
compatible:
l Sensor software to DTM-VEGASON 66 HART, PA or FF
l DTM VEGASON 66 for adjustment software PACTware™
l Indicating and adjustment module for sensor software
The parameter adjustment of the basic sensor functions is
independent of the software version. The range of available
functions depends on the respective software version of the
individual components.
The software version of VEGASON 66 can be determined as
follows:
l via PACTware™
l on the type label of the electronics
l via the indicating and adjustment module

3.2 Principle of operation
VEGASON 66 is an ultrasonic sensor for continuous level
measurement. It is particularly suitable for solids, but also good
for liquids.
The transducer of the ultrasonic sensor transmits short
ultrasonic pulses to the measured product. These pulses are
reflected by product surface and received again by the
rtansducer as echoes. The running time of the ultrasonic
pulases from emission to reception is proportional to the
distance and hence the level. The determined level is
converted into an appropriate output signal and outputted as
measured value.
Four-wire electronics with separate power supply.
The supply voltage range can differ depending on the
instrument version. The exact range is stated in the "Technical
data" in the "Supplement".
Measured value transmission is carried out via the 4 … 20 mA/
HART output separate from power supply.

. Requirement is a certain height of the
supply voltage. The eact voltage specifications are stated in
the "Technical data" in the "Supplement".
3.3 Operation
VEGASON 66 can be adjusted with four different adjustment
media:
l the adjustment module PLICSCOM
l the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g.
PACTware™ and PC
l the manufacturer-specific adjustment programs AMS™ or
PDM
l a HART handheld
The entered parameters are generally saved in VEGASON 66,
optionally also in PLICSCOM or in PACTware™.
3.4 Storage and transport
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 environ-
ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.
l Storage and transport temperature see "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General instructions
Make sure that the wetted parts of VEGASON 66, especially
the seal and process fitting, are suitable for the existing
process conditions such as pressure, temperature etc. as well
as the chemical properties of the medium.
You will find specification in chapter "Technical data" in the
"Supplement".
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module. The housing can be rotated
by 330° without the use of any tools. You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your VEGASON 66 additional protection against
moisture penetration by leading the connection cable downward in front of the cable entry. Rain and condensation water
can thus drain off. This applies mainly to mounting outdoors, in
areas where moisture is expected (e.g. by cleaning processes)
or on cooled or heated vessels.

Mounting
28783-EN-060731
The reference plane for the measuring range (version A) is the
lower edge of the flange. The reference plane for versions B, C
and D is the lower edge of the transducer.
Make sure that for all versions a min. distance - the so called
dead zone - below the reference plane is maintained in which a
measurement is not possible. The exact value of the dead
zone is stated in the "Technical data" in the "Supplement".
Information:
If the medium reaches the transducer, buildup can form on it
and cause faulty measurements later on.

Gauge pressure in the vessel does not influence VEGASON
66. Low pressure or vacuum, however, damp the ultrasonic
pulses. This influences the measuring result, particularly if the
level is very low. With pressures under -0.2 bar (-20 kPa) you
should use a different measuring principle, e.g. radar or guided
microwave.

4.3 Mounting instructions
Mount VEGASON 66 at least 500 mm (19.7 in) from the vessel
wall. If the sensor is installed in the center of vessels with
dished or round tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see
"Setup").
If this distance cannot be maintained, a false echo storage
should be carried out during setup. This applies particularly if
buildup on the vessel wall is expected. In such case, we
recommend repeating the false echo storage later on with
existing buildup.
