3 Product description
Functional principle
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropriate output signal and outputted as measured value.

Mounting instructions
Horn and parabolic
antenna
The illustrations with the following mounting instructions show a radar
sensor with horn antenna. The mounting instructions apply analogously also to the version with parabolic antenna.
Polarisation
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical wave component. By turning the instrument in the connection flange or mounting
boss, the polarisation can be used to reduce the effects of false
echoes.

Installation position
Mount the sensor at least 200 mm (7.874 in) away from the vessel
wall.

(7.87")
Fig. 5: Mounting of the radar sensor on the vessel top
If you cannot maintain this distance, you should carry out a false
signal storage during setup. This applies particularly if buildup on the
vessel wall is expected. In such a case, it is recommended to repeat
the false signal storage at a later date with existing buildup.
Inflowingmedium
Mounting should not be too close to the inflowing material as the
microwave signal will be interferred. The optimum mounting position is
on the opposite of the filling. To avoid strong pollution, the distance to
the filter or dust extraction must be as big as possible.

Tip:
The instrument is also optionally available with an antenna extension.
The antenna length can be selected (either ex works or later) to allow
the antenna to protrude slightly out of the end of the mounting socket.
Due to the antenna extension however, disturbing reflections are
generated in the close-up range. This can lead to an increase in the
4 Mounting
required minimum distance, especially with poorly reflecting media
such as plastic powder. In practice, a cleanly constructed mounting
socket, if necessary with rounded edges, introduces fewer disturbing
influences than an antenna extension.
Orientation
To measure as much of the vessel volume as possible, the sensor
should be aligned so that the measuring beam reaches the lowest
level in the vessel. In a cylindrical silo with conical outlet mounting is
carried out on a socket. It should be positioned on one third up to the
half of the vessel radius.

If mounting in the centre of the silo is not possible, the sensor can be
directed to the vessel center by using the optional swivelling holder.

Example:
In a vessel 20 m high, the installation position of the sensor is 1.4 m
from the vessel centre.
The necessary angle of inclination of 4° can be read out from this
chart.
Proceed as follows to adjust the angle of inclination with the swivelling
holder:
1. Loosen terminal screw of the swivelling holder with a fork spanner
SW 13
2. Direct the sensor, check angle of inclination
Information:
The max. angle of inclination of the swivelling holder is approx. 15°
3. Tighten the terminal screw, torque max. 20 Nm.
Information:
The hexagon screws must not be loosened.
Vessel installations
The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
Vessel installations, such as e.g. ladders, limit switches, heating spirals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring site that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
36537-EN-140209
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
Fig.15:Coversmoothprofileswithdeflectors
Agitators
VEGAPULS 68 • Profibus PA
If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
23
4 Mounting
interfering reflections from the agitators are saved with the blades in
different positions.
Fig. 16: Agitators
Material heaps
Large material heaps are detected with several sensors, 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. A mutual infuence of the
sensors is not possible.
Fig. 17: Radar sensors on traverse crane
Information:
Keep in mind that for these applications, the sensors are designed for
relatively slow level changes. When using VEGAPULS 68 on a movable bracket, the max. measuring rate must be observed (see chapter
"Technicaldata").

Instruments for a temperature range up to 250 °C or up to 450 °C
have a distance piece between process fitting and electronics housing. Ths distance piece is used for thermal decoupling of the electronics against high process temperatures.

Installation in subsurface For level measurements in concrete silos, the sensors are often
enclosures
mounted in protective boxes. These boxes can be for example metallic, closed subsurface enclosures.

36537-EN-140209
For this application, the minimal amounts of stray radiation from the
sensor can be reflected and strengthened by the walls of the subsurface enclosures. In the case of sensors with plastic housings, this can
lead to coupling disturbances. This can be avoided by using a sensor
with aluminium or stainless steel housing.

4 Mounting
Mounting in multiple
chamber silo
The silo walls of multiple chamber silos are often made of profile
walls, such as e.g. profile sheeting, to ensure the required stability. If
the radar sensor is mounted very close to a heavily structured vessel
wall, considerable false reflections can be generated. Hence the sensor should be mounted at a large distance from the separating wall.
The optimal mounting position is on the outer wall of the silo with the
sensor directed towards the emptying aperture in the silo center.

Dust layers
To avoid strong buildup and dust in the antenna system, the sensor
should not be mounted directly at the dust extraction of the vessel.
In case of extreme dust deposits in the antenna system, VEGAPULS
68 is available with a rinsing air connection. The air is distributed via
channels in the antenna system and keeps it largely free of dust.
Fig. 22: Purging air connection with horn antenna
Fig. 23: Purging air connection with parabolic antenna

The practice has shown that a pressure of approx. 0.2 … 1 bar
provides a sufficient air flow (see diagram in chapter "Technicaldata",
"Purging air connection".

Safety instructions
Connecting to the bus system
5.1
Preparing the connection
Always keep in mind the following safety instructions:
•
•
Connect only in the complete absence of line voltage
If overvoltage surges are expected, overvoltage arresters should
be installed
Voltage supply
The voltage supply is provided by a Profibus DP /PA segment coupler.
Connection cable
Connection is made with screened cable according to the Profibus
specification. Power supply and digital bus signal are carried over the
same two-wire connection cable.
The voltage supply range can differ depending on the instrument
version. You can find the data for voltage supply in chapter "Technical
data".
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal effect of the cable gland.
If you are using cable with a different diameter or cross-section,
exchange the seal or use a suitable cable gland.
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.
You can find detailed information of the cable specification, installation and topology in the "ProfibusPA-UserandInstallationGuideline" on www.profibus.com.
Cable gland ½ NPT
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technicaldata".
Cable screening and
grounding
Make sure that the cable screening and ground is executed according to the Fielbus specification. If electromagnetic interference is
expected which is above the test values of EN 61326-1 for industrial
areas, we recommend to connect the cable screen on both ends to
ground potential.
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 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).
28
VEGAPULS 68 • Profibus PA
36537-EN-140209
In systems without potential equalisation with cable screening on
both sides, 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
5 Connecting to the bus system
ceramic capacitor (e.g. 1 nF, 1500 V). Low-frequency potential equalisation currents are thus suppressed, but the protective effect against
high frequency interference signals remains.
Connection technology
5.2
Connecting
The voltage supply and signal output are connected via the springloaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Connection procedure
Proceed as follows:
1. Unscrew the housing cover
2. If a display and adjustment module is installed, remove it by turning it slightly to the left.
3. Loosen compression nut of the cable entry gland
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

Set instrument address
An address must be assigned to each Profibus PA instrument. The
approved addresses are between 0 and 126. Each address must
only be assigned once in the Profibus PA network. The sensor is only
recognized by the control system if the address is set correctly.
When the instrument is shipped, address 126 is adjusted. This address can be used for function test of the instrument and for connection to a Profibus PA network. Then address must be changed to
integrate additional instruments.
The address setting is carried out either via:
•
•
•
Hardware addressing
The address selection switch in the electronics compartment of
the instrument (address setting via hardware)
The display and adjustment module (address setting via software)
PACTware/DTM (address setting via software)
The hardware addressing is effective if an address <126 is adjusted
with the address selection switches on the instrument. Hence the
software addressing is no longer effective, the adjusted hardware
address is valid.

Parameter adjustment
The instrument is adapted to the application conditions via the parameter adjustment. The parameter adjustment is carried out with an
adjustment menu.
Main menu
The main menu is divided into five sections with the following functions:
Setup: Settings, for example, to measurement loop name, medium,
application, vessel, adjustment, AI FB 1 Channel - scaling - damping
Display: Language setting, settings for the measured value indication
as well as lighting
Diagnosis: Information, for example on the instrument status, pointer,

Further settings: Instrument units, false signal suppression, linearization, sensor address, PIN, date/time, reset, copy sensor data
Info: Instrument name, hardware and software version, date of manufacture, instrument features
36537-EN-140209
In the main menu point "Setup", the individual submenu points
should be selected one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
VEGAPULS 68 • Profibus PA
39
6 Set up with the display and adjustment module
Setup
Setup - Medium
Each medium has different reflection properties. With liquids, further
interfering factors are fluctuation product surface and foam generation. With bulk solids, these are dust generation, material cone and
additional echoes from the vessel wall.
To adapt the sensor to these different measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.
Through this selection, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with poor reflective properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Setup - Application
In addition to the medium, also the application, i.e. the measuring site,
can influence the measurement.
With this menu item, the sensor can be adapted to the applications.
The adjustment possibilities depend on the selection "Liquid" or "Bulk
solid" under "Medium".
The following options are available when "Liquid" is selected:
The selection "Standpipe" opens a new window in which the inner
diameter of the applied standpipe is entered.

Through this selection, the sensor is adapted optimally to the application or the location and measurement reliability under the various
basic conditions is increased considerably.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Setup - Vessel height,
measuring range
With this selection, the operating range of the sensor is adapted to
the vessel height and the reliability with different frame conditions is
increased considerably.
Independent from this, the min. adjustment must be carried out.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Setup - Vessel form
Also the vessel form can influence the measurement apart from the
medium and the application. To adapt the sensor to these measurement conditions, this menu item offers you different options for vessel
bottom and ceiling in case of certain applications.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Setup - Adjustment
Since the radar sensor is a distance measuring instrument, the
distance from the sensor to the product surface is measured. For
indication of the real level, an allocation of the measured distance to
the percentage height must be carried out.
To perform the adjustment, enter the distance with full and empty vessel, see the following example:

Min. level = max. meas. distance
Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specifications is always the seal surface of the thread or flange. You
can find specifications of the reference plane in chapter "Technical
data". By means of these settings, the real level will be calculated.
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.
Setup - Min. adjustment
Proceed as follows:
1. Select the menu item "Setup" with [->] and confirm with [OK].
Now select with [->] the menu item "Min. adjustment" and confirm

Diagnosis - Measurement When non-contact level sensors are used, the measurement can be
reliability
influenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. With a functioning measurement, the values are > 10 dB.
6 Set up with the display and adjustment module
Diagnoses - Curve indica- The "Echocurve" shows the signal strength of the echoes over the
tion
measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.
The "False signal suppression" displays the saved false echoes (see
menu "Additional settings") of the empty vessel with signal strength in
"dB" over the measuring range.
A comparison of echo curve and false signal suppression allows a
more detailed statement of the reliability.
The selected curve is permanently updated. A submenu with zoom
functions is opened with the [OK] key:

"X-Zoom": Zoom function for the meas. distance
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"
"Unzoom": Reset the presentation to the nominal measuring range

With the function "Echocurvememory" the echo curve can be saved
at the time of setup. This is generally recommended; for using the Asset Management functions it is absolutely necessary. If possible, the
curve should be saved with a low level in the vessel.
36537-EN-140209
With the adjustment software PACTware and the PC, the high resolution echo curve can be displayed and used to recognize signal
changes over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.

6 Set up with the display and adjustment module
Note:
A false signal suppression detects, marks and saves these false signals so that they are no longer taken into account for level measurement.
This should be done with the low level so that all potential interfering
reflections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and confirm
with [OK]. With [->] you have to select the menu item "False
signal suppression" and confirm with [OK].
2. Confirm again with [OK].
3. Confirm again with [OK].
4. Confirm again with [OK] and enter the actual distance from the
sensor to the product surface.
5. All interfering signals in this section are detected by the sensor
and stored 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 a false
echo. The filling level would then no longer be detectable in this area.
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":
50
VEGAPULS 68 • Profibus PA
36537-EN-140209
The menu item "Delete" is used to completely delete an already created false signal suppression. This is useful if the saved false signal
suppression no longer matches the metrological conditions in the
vessel.
6 Set up with the display and adjustment module
The menu item "Extend" is used to extend an already created false
signal suppression. This is useful if a false signal suppression was
carried out with a too high level and not all false signals could be detected. When selecting "Extend", the distance to the product surface
of the created false signal suppression is displayed. This value can
now be changed and the false signal suppression can be extended to
this range.
Additional adjustments Linearization curve
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal 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 parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.
Caution:
Note the following if the instrument with corresponding approval is
used as part of an overfill protection system according to WHG:
If a linearization curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when adjusting the switching point on the limit signal
transmitter.

Saving the parameter adjustment data
We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.
If the instrument is equipped with a display and adjustment module,
the data in the sensor can be saved in the display and adjustment
module. The procedure is described in the operating instructions
manual "Display and adjustment module" in the menu item "Copy
sensor data". The data remain there permanently even if the sensor
power supply fails.
The following data or settings for adjustment of the display and adjustment module are saved:
•
•
•
All data of the menu "Setup" and "Display"
In the menu "Additional adjustments" the items "Sensor-specific
units, temperature unit and linearization"

Parameter adjustment
For parameter adjustment of the sensor via a Windows PC, the configuration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collection. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older firmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manual "DTMCollection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descriptions are available in the online help of PACTware and the DTMs.

Maintenance
If the device is used correctly, no maintenance is required in normal
operation.
In some applications, buildup on the antenna system can influence
the measuring result. Depending on the sensor and application, make
arrangements to avoid strong pollution of the antenna system. If necessary, clean the antenna system in certain intervals.
9.2
Measured value and event memory
The instrument has several memories which are available for diagnosis purposes. The data remain even with voltage interruption.
Measured value memory
Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:
•
•
•
•
•
•
•
•
Distance
Filling height
Percentage value
Lin. percent
Scaled
Current value
Meas. reliability
Electronics temperature
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Event memory
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
•
•
•
•
Modification of a parameter
Switch-on and switch-off times
Status messages (according to NE 107)
Error messages (according to NE 107)
36537-EN-140209
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
Echo curve memory
The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measurement conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:

Rectify faults
Reaction when malfunctions occur
The operator of the system is responsible for taking suitable measures to rectify faults.
Procedure for fault rectification
The first measures are:
•
•
•
Evaluation of fault messages, for example via the display and
adjustment module
Checking the output signal
Treatment of measurement errors
Further comprehensive diagnostics options are available with a PC
with PACTware and the suitable DTM. In many cases, the reasons can
be determined in this way and faults rectified.
Treatment of measurement errors with bulk
solids
The below tables show typical examples for application-relevant
measurement errors with bulk solids. There are two measurement
errors:
•
•
•
Constant level
Filling

also be the fault setting of the current output to "Hold value"
In case of a too low level indication, the reason could be a line
resistance that is too high

11.2 CommunicationProfibusPA
Instrumentmasterfile
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 Profibus network planning tool. This file is installed automatically when the GSD file is integrated. The bitmap file is used for symbolic indication of the PA instrument in the configuration tool.
ID 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. Optionally to this
manufacturer-specific GSD file, PNO provides also a general so-called profile-specific GSD file. 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. When using the
instruments on a segment coupler SK-2 or SK-3, no special GSD files are required.
The following table shows the instrument ID and the GSD file names for VEGAPULS radar sensors.

FunctionBlock
Module of the PA sensors
For the cyclic data traffic, VEGAPULS 68 provides the following modules:
•
•
•
•
AI FB1 (OUT)
– Out value of the AI FB1 after scaling
AI FB2 (OUT)
– Out value of the AI FB2 after scaling
AI FB3 (OUT)
– Out value of the AI FB3 after scaling
Free Place
– This module must be used if a value in the data telegram of the cyclical data traffic should not
be used (e.g. replacement of temperature and Additional Cyclic Value)
Note:
The modules are available in two versions:
•
76
Short for Profibus master supporting only one "Identifier Format" byte, e.g. Allen
Bradley
VEGAPULS 68 • Profibus PA
36537-EN-140209
A maximum of 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.
11 Supplement
•
Long for Profibus master only supporting the "Identifier Format" byte, e.g. Siemens
S7-300/400
