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.

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.

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.

In vessels with conical vessel bottom it can be advantageous
to direct the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel
bottom.

Preferably the transducer should be mounted without socket
flush to the vessel top.

28783-EN-060731
If the reflective properties of the medium are good, you can
mount VEGASON 66 on a socket piece. The socket end
should be smooth and burr-free, if possible also rounded.
Carry out a false echo storage.
In liquids, direct the sensor as perpendicular as possible to the
product surface to achieve optimum measurement results.
Fig. 10: Orientation in liquids
To optimally align the sensor to solid products, a swivelling
holder can be implemented.
The ultrasonic sensor should be installed at a location where
no installations cross the ultrasonic beam.
Vessel installations such as for example, ladders, limit
switches, heating spirals, struts etc. can cause false echoes
superimposed on the useful echo. Make sure when planning
your measuring site that the ultrasonic signals have "free
access" to the measured product.
If there are existing vessel installations, a false echo storage
should be carried out during setup.
If large vessel installations such as struts or supports cause
false echoes, these can be attenuated through supplementary
measures. Small, inclined sheet metal or plastic baffles above
the installations scatter the ultrasonic signals and avoid direct
false echoes.

If there are agitators in the vessel, a false echo storage should
be carried out with the agitators in motion. This ensures that
the interfering reflections from the agitators are saved with the
blades in different positions.
Fig. 12: Agitators
Large material heaps are detected with several instruments,
which can be mounted on e.g. traverse cranes. For this type of
application, it is best to orient the sensor toward the solid
surface.

Through the action of filling, stirring and other processes in the
vessel, dense foams which considerably damp the emitted
signals may form on the product surface.
If foams are causing measurement errors, the sensor should
be used in a standpipe or, alternatively, the more suitable
guided radar sensors (TDR) should be used.
Guided radar is not influenced by foam generation and is
particularly suitable for such applications.
If there are strong air currents in the vessel, e.g. due to strong
winds in outdoor installations, or because of air turbulence, e.
g. by cyclone exhaustion you should mount VEGASON 66 in a
standpipe or use a different measuring principle, e.g. radar or
guided radar (TDR).
Strong heat fluctuations, e.g. caused by the sun, can cause
measurement errors. In this case, you should use a sun shield.

5 Connecting to voltage supply
5.1 Preparing the connection
Generally not 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 FS-LB-I and ÜSB
62-36G.X.
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
If reliable separation is required, power supply with mains
voltage and current output are transmitted via separate twowire connection cables. The supply voltage range can differ
depending on the instrument version. The exact range is
stated in the "Technical data" in the "Supplement".
This instrument is designed in protection class I. To maintain
this protection class, it is absolutely necessary that the ground
conductor be connected to the internal ground terminal. Take
note of the general installation regulations.
As a rule, connect VEGASON 66 to vessel ground (potential
euqalisation) or in case of plastic vessels to the next ground
potential. For this purpose, there is a ground terminal on the
side of the instrument housing.
For power supply, an approved installation cable with PE
conductor is necessary.
The 4 … 20 mA current output is connected with standard twowire cable without screen. If strong electromagnetic interference is expected, screened cable should be used.
An outer cable diameter of 5 … 9 mm ensures the seal effect
of the respective cable entry.
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 signals remains.
Take note of the corresponding installation regulations for Ex
applications. In particular, make sure that no potential equalisation currents flow over the cable screen. In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.
5.2 Connection steps
Proceed as follows:
1 Unscrew the housing cover
2 Loosen compression nut of the cable entry
3 Remove approx. 10 cm (4 in) of the cable mantle (current
output), strip approx. 1 cm (0.4 in) insulation from the ends
of the individual wires
4 Insert the cable into the sensor through the cable entry
5 Lift the opening levers of the terminals with a screwdriver
6 Insert the wire ends into the open terminals according to
the wiring plan
7 Press the opening lever of the terminals downward, you will
hear the terminal spring closing
8 Check the hold of the wires in the terminals by lightly
pulling on them
9 Connect the screen to the internal ground terminal and the
external ground terminal to potential equalisation
10 Tighten the compression nut of the cable entry, the seal
ring must completely encircle the cable
11 Connect the lead cable for power supply in the same way
acc. to the wiring plan, in addition connect the ground
conductor to the inner ground terminal.
12 Screw the housing cover back on
The electrical connection is hence finished.

6.4 Setup procedure
In HART-Multidrop mode (several sensors on one input) the
address must be set before continuing with the parameter
adjustment. You will find a detailed description in the
Operating instructions manual "Indicating and adjustment
module" or in the online help of PACTware™ or DTM.
HART mode
Standard
Address 0
As VEGASON 66 is a distance measuring instrument, the
distance from the sensor to the product surface is measured.
To have the real product level displayed, an allocation of the
measured distance to the percentage height must be made. To
carry out this adjustment, the distance is entered with full and
empty vessel. If these values are not known, an adjustment
with the distance values, e.g. 10 % and 90 % is also possible.
Starting point for these distance specifications is always the
the lower side of the flange (flange version, for all other
versions the lower side of the transducer.
The actual level is then calculated on the basis of these
entered values. At the same time, the operating range of the
sensor is limited from maximum range to the requested range.
The real product level during this adjustment is not important,
because the min./max. adjustment is always carried out
without changing the product level. These settings can be
made ahead of time without the instrument having to be
installed.
In the main menu item "Basic adjustment", the individual
submenu items should be selected one after the other and
provided with the correct parameter values.
Start your parameter adjustment with the following menu items
of the basic adjustment:
Proceed as follows:
1 Move from the measured value display to the main menu
by pushing [OK].

With solids, you can also choose between "Powder/Dust",
"Granular/Pellets" or "Ballast/Pebbels".
Through this additional selection, the sensor is adapted
perfectly to the product and measurement reliability, particularly in products with bad reflective properties, is considerably
increased.
Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
Apart from the medium, the vessel shape can also influence
the measurement. To adapt the sensor to these measuring
conditions, this menu item offers different options depending
on whether liquid or solid is selected. With "Liquid" these are
"Storage tank", "Stilling tube", "Open vessel" or "Stirred
vessel", with "Solid", "Silo" or "Bunker".

To suppress fluctuations in the measured value display, e.g.
by fluctuating product surfaces, an integration time can be set.
This time can be between 0 and 999 seconds. Keep in mind
that also the reaction time of the complete measurement will
be bigger and the sensor will react on measured value
changes with a delay. In general a time of a few seconds will
be sufficient to smooth the measured value display.

A linearization is necessary for all vessels in which the vessel
volume does not increase linearly with the level - e.g. with a
cylindrical or spherical tank - and the indication or output of the
volume is required. Corresponding linearization curves are
preprogrammed for these vessels. They represent the
correlation between the level percentage and vessel volume.
By activating the appropriate curve, the volume percentage of
the vessel is displayed correctly. If the volume should not be
displayed in percent but e.g. in l or kg, a scaling can be also
set in the menu item "Display".

High sockets or vessel installations, such as e.g. struts or
agitators as well as buildup and weld joints on the vessel walls
cause interfering reflections which can impair the measurement. A false echo storage detects and marks these false
echoes, so that they are no longer taken into account for the
level measurement. A false echo memory should be created
with empty vessel so that all potential interfering reflections will
be detected.

displayed.
3 Confirm "False signal suppression - Change now" with
[OK] and select in the below menu "Create new". Enter the
actual distance from the sensor to the product surface. All
false signals in this area are detected by the sensor and
saved after confirming with [OK].
Note:
Check the distance to the product surface, because if an
incorrect (too large) value is entered, the existing level will be
saved as false signal. The filling level would then no longer be
detectable in this area.
Additional adjustment and diagnosis options such as e.g.
scaling, simulation or trend curve presentation are shown in
