Product description
29261-EN-050202
The antenna of the radar sensor emits short radar
pulses with a duration of approx.1ns.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.
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.
3.3Adjustment
VEGAPULS 68 can be adjusted with three different
adjustment media:
lthe indicating and adjustment module PLICSCOM
lan adjustment software acc.to FDT/DTM standard,

4.1General instructions
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°).
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.
Fig.2:Measures against moisture penetration
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.

When mounting the sensor,keep a distance of at least
200 mm (7.9in)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.

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.

Fig.11:Orientation in liquids
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.
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.

5Connecting to power supply
5.1Preparing the connection
Always observe the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltages are expected,overvoltage arresters
should be installed.
Tip:
We recommend VEGA overvoltage arresters ÜS-F-LB-I
and ÜSB 62-36G.X.
In hazardous areas you should take note of the
appropriate regulations,conformity and type approval
certificates of the sensors and power supply units.
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 VEGA-
METs meet this requirement.
Bear in mind the following factors regarding supply
voltage:
lthe reduction of the output voltage of the power
supply unit under nominal load (with a sensor current
of 20.5mAor 22 mAin case of fault signal)
lthe influence of additional instruments in the circuit
(see load values in Technical data)
VEGAPULS 68 is connected with standard two-wire
cable without screen.An outer cable diameter of 5...
9mm ensures the seal effect of the cable entry.If
electromagnetic interference is expected,we recom-
mend the use of screened cable.

22 VEGAPULS 68 -4... 20 mA/HART
Connecting to power supply
29261-EN-050202
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.1nF,1500 V). The low
frequency potential equalisation currents are thus sup-
pressed,but the protective effect against high frequency
interference signals remains.
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.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2IfaPLICSCOM indicating and adjustment module is
installed,remove it by turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,
strip approx.1cm (0.4in)insulation from the ends of
the individual wires
5Insert the cable into the sensor through the cable
entry
6Lift the opening levers of the terminals with a
screwdriver (see following illustration)
7Insert the wire ends into the open terminals

6.4Setup procedure
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:
linternal check of the electronics
lindication of the instrument type,the firmware version
as well as the sensor TAGs(sensor name)
lOutput 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)
InHART-Multidrop mode (several sensors on one input)
the address must be set before continuing with the
parameter adjustment.You will find a detailed descrip-
tion in the operating instructions manual of PLICSCOM
or in the online help of PACTware™or DTM.

Standard
Address 0
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 distan-
ces,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
1)The values correspond to the actual level as well as to the settings
already carried out,e.g.default setting.

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

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.
In liquids,fluctuating surfaces and foam generation are
further interfering factors.To adapt the sensor to the
different conditions,a general selection is made in this
menu item,i.e.Solid or Liquid.

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 0and 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 corre-
sponding delay.In general,a time of a few seconds is
sufficient to smooth the measured value display.

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 false reflections which influence the
measurement.Afalse echo storage detects and marks
these false echoes so that they are no longer taken into
account for the level measurement.Afalse echo
memory should be created with empty vessel so that all
probably existing false reflections can be detected.

8Maintenance and fault rectification
8.1Maintenance
When used as directed in normal operation,VEGAPULS
68 is completely maintenance-free.
8.2Fault rectification
VEGAPULS 68 offers maximum reliability.Nevertheless,
faults may occur during operation.These can have the
following causes,e.g.:
lSensor
lProcess
lPower supply
lSignal processing.
The first measures to be taken are to check the output
signal and evaluate fault messages via the adjustment
module PLICSCOM.The procedure is described below.
Further comprehensive diagnostics can be carried out
on a laptop with the software PACTware™and the
suitable DTM.In many cases,the reasons can be
determined in this way and faults can be rectified.
Should these measures not be successful,please call in
urgent cases the VEGA service hotline under the phone
number +49 1805 858550.
The hotline is available to you 7days a week round-the-
clock.Since we offer this service world-wide,the
support is only available in the English language.The
service is free of charge,only the standard telephone
costs will be charged.
Connect a hand-held multimeter with a suitable measu-
ring range acc.to the wiring plan.

8.3Exchanging the oscillator
If the electronics module is defective,it can be replaced
by the user
Oscillator PS-E.60SH.is suitable for VEGAPULS 68 –4
... 20 mA/HART.The following versions are available:
lPS-E.60SHX(without approvals)
lPS-E.60SHC(approvals XM,CX,CM,CK,CI,DX,
DM,DK,DI;EX,GX,UX,UF acc.to VEGA product
list)
InEx applications,only an oscillator with appropriate Ex
approval must be used.
If there is no oscillator available on site,it can be ordered
from the responsible VEGA agency.
The new oscillator must be according to the order data
of the sensor.These can be loaded as follows:
lat the premises by VEGA
lon site by the user.
Information:
When loading on site,first of all the respective file must
be downloaded from the Internet (see Setup).
In both cases,the serial number of VEGAPULS 68 is
necessary.The serial numbers are stated on the type
label of VEGAPULS 68 or on the delivery note.

The electronics exchange is finished.
As a rule,the exchange of the oscillator must be
documented internally when used in Ex applications.
If the serial number of the oscillator is stated when
ordering,VEGAPULS 68 is ready for operation directly
after mounting the oscillator.
If you are using an universal electronics from stock,you
have to load the sensor data after mounting the
oscillator.Use the item "serial number search"under
www.vega.com.After having entered the serial number,
the order data of the sensor will be displayed.Below the
order data you will find "Sensor data for Service-DTM"
as an XML file.Load this file to your PC and then into the
sensor via PACTware™/Service DTM.
After VEGAPULS 68 is ready for operation,settings
carried out on site must be repeated.
Tip:
Use the copy function of the adjustment module
PLICSCOM or the adjustment software PACTware™.
