bulk solids also under arduous process conditions and large measur-
ing ranges. It the ideal solution for level measurement in high silos,
large�bunkers,�stone�crushers�and�melting�furnaces.�With�different�
antenna versions and materials, this sensor is the optimum solution
for virtually all applications and processes.
The instrument is also suitable for applications in liquids.
Dependent�on�the�application�range,�different�versions�are�used:
• Small silos and vessels, measurement of virtually all bulk solids:
Horn antenna
• Large�silos�and�vessels,�measurement�of�bulk�solids�with�low�εr
value: Parabolic antenna
• Liquids: Parabolic antenna
The�instrument�can�be�used�with�products�with�an�εr�value�≥1.5.�The�
actually achievable value depends on the measuring conditions and
the antenna system.

VEGAPULS 68 • Foundation Fieldbus
36538-EN-170405
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 appropri-
ate output signal and outputted as measured value.
3.3

General instructions
On�instruments�with�threaded�process�fitting,�the�hexagon�must�be�
tightened�with�a�suitable�wrench.�For�the�proper�wrench�size�see�
chapter "Dimensions".
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• When�mounting�horizontally,�turn�the�housing�so�that�the�cable�
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Make sure before mounting that all parts of the instrument exposed to
the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Process�fitting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion�and�mechanical�influences
You�can�find�detailed�information�on�the�process�conditions�in�chapter�
"Technical data" as well as on the type label.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection. The dust protection caps do
not�provide�sufficient�protection�against�moisture.

Mounting instructions
The illustrations with the following mounting instructions show a radar
sensor with horn antenna. The mounting instructions apply analo-
gously also to the version with parabolic antenna.
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical wave compo-
nent.�By�turning�the�instrument�in�the�connection�flange�or�mounting�
boss,�the�polarisation�can�be�used�to�reduce�the�effects�of�false�

If you cannot maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup on
the vessel wall is expected. In such cases, we recommend repeating
the false signal suppression at a later date with existing buildup.

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
VEGAPULS 68 • Foundation Fieldbus
36538-EN-170405
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.
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.

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
table.
To adjust the angle of inclination with the swivelling holder see next
section.
Proceed as follows to align the sensor with the swivelling holder:
1. Loosen terminal screw of the swivelling holder with a fork spanner
SW 13

Information:
The hexagon screws must not be loosened.
2. Align the sensor, check angle of inclination. Max. angle of inclina-
tion of the swivelling holder see chapter "Dimensions"
3. Re-tighten the terminal screw, max. torque see chapter "Technical
data".
The mounting location of the radar sensor should be a place where no
other�equipment�or�fixtures�cross�the�path�of�the�radar�signals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.

Vessel installations
VEGAPULS 68 • Foundation Fieldbus

In case of existing vessel installations, a false signal suppression
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�baffles�above�the�installations�scatter�the�
radar�signals�and�prevent�direct�interfering�reflections.
Fig.�17:�Cover�flat,�large-area�profiles�with�deflectors
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�reflections�from�the�agitators�are�saved�with�the�blades�in�
different�positions.
Fig. 18: Agitators
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.

Information:
Keep in mind that for these applications, the sensors are designed for
relatively slow level changes. When using VEGAPULS 68 on a mov-
able 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�fitting�and�electronics�hous-
ing. Ths distance piece is used for thermal decoupling of the electron-
ics against high process temperatures.
Information:
The spacer may only be incorporated up to a maximum of 50 mm into
the vessel insulation. Only then is a reliable temperature decoupling
guaranteed.

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

For this application, the minimal amounts of stray radiation from the
sensor�can�be�reflected�and�strengthened�by�the�walls�of�the�subsur-
face 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�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�sen-
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.

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.

Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
• The electrical connection must only be carried out by trained
personnel authorised by the plant operator.
• If overvoltage surges are expected, overvoltage arresters should
be installed.
The instrument requires a operating voltage of 9 … 32 V DC. Operat-
ing voltage and the digital bus signal are carried on the same two-wire
connection cable. Power is supplied via the H1 power supply.
Connection is carried out with screened cable according to Fieldbus
specification.
Use cable with round cross section for instruments with housing and
cable�gland.�To�ensure�the�seal�effect�of�the�cable�gland�(IP�protection�
rating),�find�out�which�cable�outer�diameter�the�cable�gland�is�suitable�
for.
Use�a�cable�gland�fitting�the�cable�diameter.
Make sure that the entire installation is carried out according to the
Fieldbus�specification.�In�particular,�make�sure�that�the�bus�is�termi-
nated with suitable terminating resistors.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
On plastic housings, the NPT cable gland or the Conduit steel tube
must be screwed into the threaded insert without grease.
Max. torque for all housings, see chapter "Technical data".
Make sure that the cable screen and grounding are carried out ac-
cording�to�Fieldbus�specification.�We�recommend�to�connect�the�
cable screen to ground potential on both ends.
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

on the housing must be connected to the potential equalisation (low
impedance).
5.2
Connecting
The voltage supply and signal output are connected via the spring-
loaded 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.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left.
3. Loosen compression nut of the cable gland and remove blind
plug
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

After VEGAPULS 68 is connected to the bus system, the instrument
carries out a self-test for approx. 30 seconds. The following steps are
carried out:
• Internal check of the electronics
• Indication of a status message, e.g. "F 105 Determine measured
value" on the display or PC
• Status�byte�goes�briefly�to�fault�value
Then the actual measured value is outputted to the signal cable. The
value takes into account settings that have already been carried out,
e.g. default setting.

In the main menu item "Setup", the individual submenu items
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.
Setup
Every�medium�has�different�reflective�properties.�With�liquids,�there�
are additional interfering factors such as turbulent product surface
and foam generation. With bulk solids, the additional interfering fac-
tors are dust generation, angle of repose and secondary 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 optimally adapted to the product,
and�measurement�certainty,�particularly�in�products�with�poor�reflec-
tive 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.
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:
Setup - Medium
Setup - Application

urements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de-
signed for interface measurement.
Through this selection the operating range of the sensor is adapted
to the vessel height, which considerably increases measurement
certainty�under�different�basic�conditions.
The min. adjustment must be carried out independently of this.
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.
Apart from the medium and the application, the vessel form itself can
influence�the�measurement.�To�adapt�the�sensor�to�these�measuring�
conditions,�this�menu�item�offers�different�options�for�vessel�bottom�
and ceiling for certain applications.
Enter the requested parameters via the appropriate keys, save your

Since the radar sensor is a distance measuring instrument, it is the
distance from the sensor to the product surface that is measured. To
indicate the actual level, the measured distance must be assigned to
a certain height percentage.

Saving the parameterisation data
We recommended writing down the adjustment data, e.g. in this op-
erating 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 menu item "Copy device
settings" in the menu "Additional settings". The data remain there
permanently even if the sensor power supply fails.
The following data or settings for adjustment of the display and ad-
justment module are saved:
• All data of the menu "Setup" and "Display"
• The items "Sensor-specific�units,�temperature�unit�and�linearisa-
tion" in the menu "Additional settings".
• The values of the user-programmable linearisation curve
The function can also be used to transfer settings from one instru-
ment to another instrument of the same type. If it is necessary to
exchange a sensor, the display and adjustment module is inserted
into the replacement instrument and the data are likewise written into
the sensor via the menu item "Copy device settings".

Maintenance
If the instrument 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, take
measures to avoid heavy soiling 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 available for diagnostic pur-
poses. The data remain there even in case of voltage interruption.
Up to 100,000 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. certainty
• 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:
• Modification�of�a�parameter
• Switch-on�and�switch-off�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:

Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The�first�measures�are:
• Evaluation of fault messages via the adjustment device
• 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.
The below tables show typical examples of application-related
measurement errors with bulk solids. A distinction is made between
measurement errors during:
• Constant level
• Filling
• Emptying
The images in column "Error pattern" show the real level as a broken
line and the level displayed by the sensor as a continuous line.

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,�the�order�data�must�first�be�downloaded�from�

ent time constants with the primary and secondary process measurement.
Fig. 60: Schematic presentation function block PID Control
Function block Output Splitter
The function block "Output Splitter" generates two control outputs out of one input. Each output is
a linear image of a part of the input. A retrograde calculation function is realised by using the linear
imaging function inversely. A cascading of several Output Splitters is supported by an integrated
decision table for the combinability of inputs and outputs.
Fig. 61: Schematic presentation function block Output Splitter
Function block Signal Characterizer
The function block "Signal Characterizer" has two channels the outputs of which are not in linear
relation�with�the�respective�input.�The�non-linear�relation�is�defined�by�a�look-up�table�with�individu-
ally selectable x/y-pairs. The respective input signal is imaged on the corresponding output, hence
this function block can be used in a control loop or signal path. Optionally the function axis can be
exchanged in channel 2 so that the block can be also used in a reverse control loop.

Function block Integrator
The function block "Integrator" integrates a continuous input signal over the time and sums the
results�of�an�impulse�input�block.�It�is�used�as�a�totalizer�up�to�a�reset�or�as�a�subtotalizer�up�to�a�
reference point at which the integrated and accumulated value is compared with the default values.
When these default values are reached, digital output signals will be outputted. The integration func-
tion�is�carried�out�upwardly�starting�with�zero�and�downwards�with�a�default�value.�Two�flow�values�
are�also�available�so�that�the�net�flow�volume�can�be�calculated�and�integrated.�This�can�be�used�for�
calculation�of�volume�and�mass�changes�in�the�vessel�or�for�optimisation�of�flow�controls.

Function block Input Selector
The function block "Input Selector"�offers�selection�possibilities�for�up�to�four�inputs�and�generates�
an output signal according to the selection criteria. Typical input signals are AI blocks. Selection
possibilities�are�maximum,�minimum,�mean�value,�average�value�and�first�useful�signal.�Through�
parameter combination, the block can be used as rotary switch or as preselection switch for the
