3.2 Principle of operation
Area of application
VEGAPULS 68 is a radar sensor in K-band technology
for continuous level measurement.
A version of VEGAPULS 68 is available for the
respective application:
VEGAPULS 68 - 4 ... 20 mA/HART
29261-EN-050202
10
The version with horn antenna is particularly suitable
for small silos and vessels for measurement of
virtually all solids.
The version with parabolic antenna is particularly
suitable for large silos and vessels with up to 70 m
(76 yd) measuring distance and for measurement of
solids with small dielectric value.
Product description
Physical 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 running 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.
Power supply
Two-wire electronics 4 ... 20 mA/HART for power supply
and measured value transmission on the same cable.
The power supply range can differ depending on the
instrument version. The exact range is stated in the
Technical data in the Supplement.
3.3 Adjustment
VEGAPULS 68 can be adjusted with three different
adjustment media:
the indicating and adjustment module PLICSCOM
an adjustment software acc. to FDT/DTM standard,
e.g. PACTware™ and PC
l a HART handheld
The entered parameters are generally saved in VEGAPULS 68, optionally also in PLICSCOM or in
PACTware™.
3.4 Storage and transport
29261-EN-050202
Packaging
Your instrument was protected by packaging during
transport. Its capacity to handle normal loads during
transport is assured by a test acc. to EN 24180.

4.1 General instructions
Installation position
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of
an indicating and adjustment module PLICSCOM. The
housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment
module PLICSCOM in four different positions (each
displaced by 90°).
Moisture
Use the recommended cable (see chapter "Connecting
to power supply") and tighten the cable entry.
You can give your VEGAPULS 68 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.

29261-EN-050202
Measuring range
The reference plane for the measuring range is the lower
edge of the flange or the seal surface of the thread.
Information:
If the product reaches the antenna, buildup can form on
it over a period of time and later cause measurement
errors.

Mounting
Installation location
When mounting the sensor, keep a distance of at least
200 mm (7.9 in) to the vessel wall. If the sensor is
installed in the center of concave or arched vessel tops,
multiple echoes can arise. These can, however, be
faded out 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
this case, we recommend repeating the false echo
storage later on with existing buildup.
> 200 mm

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

The version with swivelling holder ensures optimum
orientation of the sensor to the solid cone.
Loosen the screw on the swivelling holder with a flat
wrench SW 13, direct the sensor and retighten the
screw, torque max. 20 Nm.
Vessel installations
The radar sensor should be installed at a location where
no installations cross the radar signals.
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 location that the radar
signals have "free access" 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
baffles above the installations scatter the radar signals
and avoid a direct false echo reflection.

Connecting to power supply
5 Connecting to power supply
5.1 Preparing the connection
Note safety instructions
Always observe the following safety instructions:
Connect only in the complete absence of line voltage
If overvoltages are expected, overvoltage arresters
should be installed.
Tip:
We recommend VEGA overvoltage arresters ÜS-F-LB-I
and ÜSB 62-36G.X.
Take note of safety
instructions for Ex
applications
In hazardous areas you should take note of the
appropriate regulations, conformity and type approval
certificates of the sensors and power supply units.
Select power supply
Power supply and current signal are transmitted via the
same two-wire connection cable. The power supply
range can differ depending on the instrument version.
The exact range is stated in the Technical data in the
Supplement.
Provide a reliable separation between the supply circuit
and the mains circuits acc. to DIN VDE 0106 part 101.
The VEGA power supply units VEGATRENN 149AEx,
VEGASTAB 690, VEGADIS 371 as well as all VEGAMETs meet this requirement.
Bear in mind the following factors regarding supply
voltage:
Select connection cable
VEGAPULS 68 is connected with standard two-wire
cable without screen. An outer cable diameter of 5 ...
9 mm ensures the seal effect of the cable entry. If
electromagnetic interference is expected, we recommend the use of screened cable.
VEGAPULS 68 - 4 ... 20 mA/HART
29261-EN-050202
22
the reduction of the output voltage of the power
supply unit under nominal load (with a sensor current
of 20.5 mA or 22 mA in case of fault signal)
the influence of additional instruments in the circuit
(see load values in Technical data)
Connecting to power supply
Cable screening and
grounding
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 outside on the housing must be connected to
the potential equalisation (low impedance).
If potential equalisation currents are expected, the
connection on the evaluation 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.
Select connection
cable for 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 procedure
Proceed as follows:
1 Unscrew the housing cover
2 If a PLICSCOM indicating 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) insulation from the ends of
the individual wires
5 Insert the cable into the sensor through the cable
entry
29261-EN-050202
6 Lift the opening levers of the terminals with a
screwdriver (see following illustration)
7 Insert the wire ends into the open terminals
according to the wiring plan
8 Press down the opening levers of the terminals, you
will hear the terminal spring closing

9 Check the hold of the wires in the terminals by lightly
pulling on them
10 Connect the screen to the internal ground terminal
and the external ground terminal to potential equalisation
11 Tighten the compression nut of the cable entry, the
seal ring must completely encircle the cable

Adjustment system
The sensor is adjusted via the four keys of the indicating
and adjustment module PLICSCOM. The LC display
indicates the individual menu items. The functions of the
individual keys are shown in the above illustration.
Approx. 10 minutes after the last pressing of a key, an
automatic reset to measured value indication is trigger-

Setup with the indicating and adjustment module PLICSCOM
ed. Any values not confirmed with [OK] will not be
saved.
6.4 Setup procedure
Switch on phase
After VEGAPULS 68 is connected to power supply or
after voltage recurrence, the instrument carries out a
self-test for approx. 30 seconds. The following steps are
carried out:
internal check of the electronics
indication of the instrument type, the firmware version
as well as the sensor TAGs (sensor name)
l Output signal jumps briefly (approx. 10 seconds) to
the set interference current.
Then the actual measured value is displayed and the
corresponding current is transmitted to the cable1)
Address setting HARTMultidrop
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 of PLICSCOM
or in the online help of PACTware™ or DTM.

The values correspond to the actual level as well as to the settings
already carried out, e.g. default setting.
VEGAPULS 68 - 4 ... 20 mA/HART
29261-EN-050202
Because VEGAPULS 68 is a distance measuring
instrument, the distance from the sensor to the product
surface is measured. In order to have the actual level
displayed, an allocation of the measured distance to the
percentage height must be carried out. To make this
adjustment, the full and empty distances in the vessel
are entered. If these values are not known, it is also
possible to carry out the adjustment with other distances, e.g. 10 % and 90 %. Starting point of these distance
values is always the seal surface of the thread or flange.
The actual level is then calculated on the basis of these
Setup with the indicating and adjustment module PLICSCOM
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
provided with the correct parameter values.
Start your parameter adjustment with the following menu
items of the basic adjustment:

3 Save the settings with [OK] and move to the medium
selection with [–>].
Medium selection
Each product has different reflective properties. In
solids, these are dust generation, material cones and
additional echoes caused by the vessel wall. Due to the
medium selection, the sensor is adapted in an optimum
way to the product and the accuracy, particularly for
products with bad reflective properties, is increased
considerably.
Medium
Solid
For solids you choose also Powder/Dust, Granular/
Pellets or Ballast/Pebbels.

Apart from the medium also the vessel form can
influence the measurement. To adapt the sensor to
these conditions, this menu item offers (depending on
either liquid or solid is selected) different options. For
Liquid these are Storage tank, Stilling tube, Open vessel
or Stirred vessel, for Solid Silo or Bunker.

Damping
To suppress fluctuation in the measured value display,
e.g. by agitated product surfaces, an integration time
can be set. This time can be between 0 and 999
seconds. Please note that the reaction time of the entire
measurement will be longer and the sensor will react to
quick changes of the measured value with a corresponding delay. In general, a time of a few seconds is
sufficient to smooth the measured value display.

Linearization curve
A linearization is necessary for all vessels in which the
vessel volume does not increase linearly with the level e.g. in a cylindrical or spherical tank - and the indication
or output of the volume is requested. Corresponding
linearization curves are preprogrammed for these
vessels. They represent the correlation between the
level percentage and vessel volume. By activating the

is displayed correctly. If the volume should not be
displayed in percent but e.g. in l or kg, a scaling can be
set in the menu item Display.

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

False echo storage
High sockets or vessel installations, such as e.g. struts
or agitators as well as buildup and weld joints on the
vessel walls cause false reflections which influence 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
probably existing false reflections can be detected.
