3.2 Principle of operation
The VEGAPULS SR 68 is a radar sensor for continuous measurement
of bulk solids also under dicult process conditions. It is particularly
suitable for level measurement in high silos and large bunkers.
The instrument is also suitable for applications in liquids.
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reected 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.

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 reections are
generated in the close-up range. This can lead to an increase in the
required minimum distance, especially with poorly reecting media
such as plastic powder. In practice, a cleanly constructed mounting
socket, if necessary with rounded edges, introduces fewer disturbing
inuences than an antenna extension.
To measure as much of the vessel volume as possible, the sensor

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
Agitators
The mounting location of the radar sensor should be a place where no
other equipment or xtures 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.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baes above the installations scatter the
radar signals and prevent direct interfering reections.
Fig.18:Coversmoothproleswithdeectors
If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interfering reections from the agitators are saved with the blades in
dierent positions.

Material heaps
Mounting in the vessel
insulation
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. 20: 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 SR 68 on
a movable bracket, the max. measuring rate must be observed (see
chapter "Technical data").
Instruments for a temperature range up to 250 °C or up to 450 °C
have a distance piece between process tting and electronics housing. Ths distance piece is used for thermal decoupling of the electron-
ics against high process temperatures.
Information:
The distance piece must only be incorporated up to max. 50 mm in
the vessel isolation. Only then, a reliable temperature decoupling is
guaranteed.

38296-EN-130624
VEGAPULS SR 68 • Probus PA
For level measurements in concrete silos, the sensors are often
mounted in protective boxes. These boxes can be for example metallic, closed subsurface enclosures.
1 2
Fig. 22: Mounting of the instrument in an subsurface enclosure
1 Subsurface enclosure
2 Concrete bottom
For this application, the minimal amounts of stray radiation from the
sensor can be reected 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.
The silo walls of multiple chamber silos are often made of prole
walls, such as e.g. prole sheeting, to ensure the required stability. If
the radar sensor is mounted very close to a heavily structured vessel
wall, considerable false reections can be generated. Hence the sen-
27
4 Mounting
sor 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
28
Fig. 24: Orientation of VEGAPULS SR 68 for emptying in the silo center
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
SR 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.

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
V
oltage supply
Connection cable
Cable gland ½ NPT
Cable screening and
grounding
The voltage supply is provided by a Probus DP /PA segment coupler.
The voltage supply range can dier depending on the instrument
version. You can nd the data for voltage supply in chapter "Technical
data".
Connection is made with screened cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent 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
Probus specication. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.
You can nd detailed information of the cable specication, installation and topology in the "
line" on www.probus.com.
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 "Technical data".
Make sure that the cable screening and ground is executed according to the Fielbus specication. 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.
With 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).
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

high frequency interference signals remains.
5.2 Connecting
The voltage supply and signal output are connected via the springloaded terminals in the housing.
The 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
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

to ensure the optimum adjustment of the measurement. The procedure is described in the following.
Setup
Setup - Medium
Each medium has dierent reection properties. With liquids, further
interfering factors are uctuation 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 dierent 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 reective 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
40
In addition to the medium, also the application, i.e. the measuring site,
can inuence 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:

Setup - Adjustment
38296-EN-130624
VEGAPULS SR 68 • Probus PA
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:
45
6 Set up with the display and adjustment module
Fig. 41: Parameter adjustment example min./max. adjustment
1 Min. level = max. meas. distance
2 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
specications is always the seal surface of the thread or ange. 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.

Diagnosis - Measurement
reliability
38296-EN-130624
VEGAPULS SR 68 • Probus PA
When non-contact level sensors are used, the measurement can be
inuenced 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.
47
6 Set up with the display and adjustment module
Diagnoses - Curve indication
The "Echo curve" shows the signal strength of the echoes over the
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 accurate conclusion on measurement reliability. The selected
curve is continuously updated. With the [OK] key, a submenu with
zoom functions is opened:
"X-Zoom": Zoom function for the meas. distance
•
"Y-Zoom": 1, 2, 5 and 10x signal magnication in "dB"
•
"Unzoom": Reset the presentation to the nominal measuring range
•

With the function "Echo curve memory" the echo curve can be saved
v
e
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.
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.

Additional adjustments False signal suppr
ession
The following circumstances cause interfering reections and can
inuence the measurement:
High sockets
•
Vessel installations such as struts
•
Agitators
•
Buildup or welded joints on vessel walls
•
Note:
A false signal suppression detects, marks and saves these false signals so that they are no longer taken into account for level measure-
ment.
This should be done with the low level so that all potential interfering
reections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and conrm
with [OK]. With [->] you have to select the menu item "False
signal suppression" and conrm with [OK].
2. Conrm again with [OK].
3. Conrm again with [OK].
38296-EN-130624
VEGAPULS SR 68 • Probus PA
4. Conrm 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 conrming 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 lling level would then no longer be detectable in this area.
49
6 Set up with the display and adjustment module
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":
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.
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 cur
ve
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 overll protection system according to WHG:
If a linearization curve is selected, the measuring signal is no longer
necessarily linear to the lling height. This must be considered by the
user especially when adjusting the switching point on the limit signal
transmitter.

7.2 Parameter adjustment
For parameter adjustment of the sensor via a Windows PC, the conguration 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 rmware 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 "DTM Collection/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.

Standard/Full version
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project conguration simplies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.
In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.
The standard version is available as a download under
www.vega.com/downloads and "Software". The full version is available on CD from the agency serving you.
7.3 Saving the parameter adjustment data
We recommend documenting or saving the parameter adjustment

9.1 Maintenance
If the device is used correctly, no maintenance is required in normal
operation.
In some applications, buildup on the antenna system can inuence
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
E
ent memory
v
Echo curve 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.
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:
Modication of a parameter
•
Switch-on and switch-o times
•
Status messages (according to NE 107)
•
Error messages (according to NE 107)
•
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
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 measure-
ment conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:

Checking the output signal
•
Treatment of measurement errors
•
Further comprehensive diagnostics options oer a PC with the software PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectied.

9.5 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
In Ex applications only one instrument and one electronics module
with respective Ex approval may be used.
If there is no electronics module available on site, the electronics
module can be ordered through the agency serving you. The electronics modules are adapted to the respective sensor and dier in signal
output or voltage supply.
The new electronics module must be loaded with the default settings
of the sensor. These are the options:
In the factory
•
Or on site by the user
•
In both cases, the serial number of the sensor is needed. The serial
numbers are stated on the type label of the instrument, on the inside
of the housing as well as on the delivery note.
When loading on site, rst of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics
module").

Approvals
Instruments with approvals can have dierent technical data depending on the version.
For that reason the associated approval documents of these instruments must be carefully noted.
They are part of the delivery or can be downloaded under www.vega.com and "VEGA Tools" as
well as under "Downloads" and "Approvals".
11.2 CommunicationProbusPA
Instrumentmasterle
The instrument master le (GSD) contains the characteristic data of the Probus 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 le is also provided for the Probus network planning tool. This le is installed automatically when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instrument in the conguration tool.
ID number
Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user
organisation (PNO). This ID number is also included in the name of the GSD le. Optionally to this
manufacturer-specic GSD le, PNO provides also a general so-called prole-specic GSD le. If
the general GSD le is used, the sensor must be set to the prole-specic ident number via the DTM
software. By default, the sensor operates with the manufacturer-specic ID number. When using the
instruments on a segment coupler SK-2 or SK-3, no special GSD les are required.
The following table shows the instrument ID and the GSD le names for VEGAPULS radar sensors.

The prerequisites for maintaining the protection rating are a suitable cable as well as correct mounting.

Module of the PA sensors
For the cyclic data trac, VEGAPULS SR 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 trac should not
be used (e.g. replacement of temperature and Additional Cyclic Value)
A maximum of three modules can be active. By means of the conguration software of the Probus
master you can determine the conguration of the cyclical data telegram with these modules. The
procedure depends on the respective conguration software.
Note:
The modules are available in two versions:
Short for Probus master supporting only one "Identier Format" byte, e.g. Allen
•
Bradley
Long for Probus master only supporting the "Identier Format" byte, e.g. Siemens
•
S7-300/400
