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.
Power supply of the signal output is via the Profibus DP/PA
segment coupler or VEGALOG 571 EP cards. A two-wire
cable acc. to Profibus specification serves as carrier of both
power and digital data signals for multiple sensors. The
instrument profile of VEGASON 66 corresponds to profile
specification version 3.0.
The GSD (instrument master files) and bitmap files necessary

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 does, 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.

28789-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 according to Profibus specification.
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 and current
output are transmitted via separate two-wire 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.
VEGASON 66 is connected with screened cable acc. to
Profibus specification.
An outer cable diameter of 5 … 9 mm ensures the seal effect
of the respective cable entry.
Please make sure that your installation is carried out according
to the Profibus specification. In particular, make sure that the
termination of the bus is done with appropriate terminating
resistors.
In systems with potential equalisation, connect the cable
screen directly to ground potential at the power supply unit, in
the connection box and at the sensor. The screen in the sensor

28789-EN-060731
must be connected directly to the internal ground terminal. The
ground terminal outside on the housing must be connected to
the potential equalisation (low impedance).
In systems without potential equalisation, connect the cable
screen directly to ground potential at the power supply unit and
at the sensor. In the connection box or T-distributor, the screen
of the short stub to the sensor must not be connected to
ground potential or to another cable screen. The cable screens
to the power supply unit and to the next distributor must be
connected to each other and also connected to ground
potential 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.
The total capacitance of the cable and of all capacitors must
not exceed 10 nF in Ex applications.
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

approx. 30 seconds. The following steps are carried out:
l Internal check of the electronics

Before starting the actual parameter adjustment of a Profibus
PA sensor, the address setting must first be carried out. You
will find a detailed description in the operating instructions
manual of the indicating and adjustment module or in the
online help of PACTware™ or DTM.
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:

Each product has different reflective properties. In addition,
there are various interfering factors which have to be taken into
account: agitated product surfaces and foam generation (with
liquids); dust generation, material cones and echoes from the
vessel wall (with solids). To adapt the sensor to these different
conditions, you should first select in this menu item "Liquid" or
"Solid".
Medium
Liquid
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".

Storage tank
Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
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".

Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
In this menu item you can enter an unambiguous designation
for the sensor, e.g. the measurement loop name or the tank or

With this menu item, the Basic adjustment is finished and you
can now jump to the main menu with the [ESC] key.
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

Proceed as follows:
1 Move from the measured value display to the main menu
by pushing [OK].
2 Select the menu item "Service" with [->] and confirm with
[OK]. Now the menu item "False signal suppression" is
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
the following menu schematic. You will find a detailed
description of these menu items in the operating instructions

10.2 Profibus PA
Instrument master file
The instrument master file (GSD) contains the characteristic data of the Profibus PA
instrument. These data are, e.g. the permissible transmission rates as well as information on
diagnostics values and the format of the measured value outputted by the PA instrument.
A bitmap file is also provided for the planning tool of the Profibus network. This file is
automatically installed with the GSD file. The bitmap file is used for symbolic indication of the
PA instrument in the configuration tool.
Ident number
Each Profibus instrument gets an unambiguous ident number (ID number) from the Profibus
user organisation (PNO). This ID number is also included in the name of the GSD file. For
VEGASON 66 the ID number is 0x0770(hex) and the GSD file "SN__0770.GSD". Asan
option to this manufacturer-specific GSD file, PNO provides also a general so-called profilespecific GSD file. For VEGASON 66 you have to use the general GSD file "PA139701.GSD". If
the general GSD file is used, the sensor must be set to the profile-specific ident number via the
DTM software. By default, the sensor operates with the manufacturer-specific ID number.
Note:
When using the profile-specific GSD file, the PA-OUT value as
well as the temperature value are transmitted to the PLC (see
block diagram "Cyclical data traffic").
Cyclical data traffic
The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during
operation. The below block diagram below shows which data can be accessed by the PLC.

Module of the PA sensors
For the cyclic data traffic, VEGASON 66 provides the following modules:
l AI (PA-OUT)
- PA-OUT value of the FB1 after scaling
l Temperature
- PA-OUT value of the FB2 after scaling
l Additional Cyclic Value
- Additional cyclical value (depending on the source)
l Free Place
- This module must be used if a value should not be used in the data telegram of the
cyclical data traffic (e.g. replacement of the temperature and Additional Cyclic Value)
Max. three modules can be active. By means of the configuration software of the Profibus
master, you can determine the configuration of the cyclical data telegram with these modules.
The procedure depends on the respective configuration software.
Supplement
VEGASON 66 - Profibus PA 53
28789-EN-060731
Note:
The modules are available in two versions:
l Short for Profibus master supporting only one "Identifier
Format" byte, e.g. Allen Bradley
l Long for Profibus master only supporting the "Identifier
Format" byte, e.g. Siemens S7-300/400
Examples of telegram configuration
In the following you will see how the modules can be combined and how the appendant data
telegram is structured.
