VEGAPULS 66 enamel • 4 … 20 mA/HART - four-wire
31954-EN-141215
This operating instructions manual applies to the following instrument
versions:
• Hardware version < 2.0.0
• Softwareversion≤3.8
3.2 Principle of operation
VEGAPULS 66 is a radar sensor in C-band technology for continuous
level measurement.
The version with enamelled antenna is particularly suitable for
measurement of highly corrosive liquids, preferably in enamelled ves-
selsunderdicultprocessconditionssuchasbuildup,condensation
and foam generation as well as strong product movement.
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereected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.
Four-wire electronics with separate power supply.
Thesupplyvoltagerangecandierdependingontheinstrument
version.
Thedataforpowersupplyarespeciedinchapter"Technical data".
Measuredvaluetransmissioniscarriedoutviathe4…20mA/HART
output separate from power supply.
The backlight of the display and adjustment module is powered by
the sensor.The prerequisite for this is a supply voltage at a certain
level.Theexactvoltagespecicationsarestatedinchapter"Technical
data".
3.3 Operation
The instrument can be adjusted with the following adjustment media:
• With the display and adjustment module
• withthesuitableVEGADTMinconjunctionwithanadjustment
softwareaccordingtotheFDT/DTMstandard,e.g.PACTwareand
PC
• withmanufacturer-specicadjustmentprogramsAMS™orPDM
• With a HART handheld

Instruments with enamel coating should be treated very carefully and
shocks should be avoided. Unpack VEGAPULS 66 directly before
installation. Insert VEGAPULS 66 carefully into the vessel opening
and avoid touching any sharp vessel parts.
4.2 Mounting instructions
When mounting the VEGAPULS 66, keep a distance of at least
500 mm (19.69 in) to the vessel wall. If the sensor is installed in the
center of dished or round vessel tops, multiple echoes can arise.
These can, however, be suppressed by an appropriate adjustment
(seechapter"Setup").
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 cases, we recommend repeating the
false signal storage at a later date with existing buildup.

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 for example, ladders, limit switches, heat-
ing spirals, struts etc. can cause false echoes that interfere with the
usefulecho.Makesurewhenplanningyourmeasuringsitethatthe
radarsignalshave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.

Throughtheactionoflling,stirringandotherprocessesinthevessel,
dense foams which considerably damp the emitted signals may form
on the product surface.
If foams are causing measurement errors, the biggest possible radar
antenna should be used.
As an alternative, sensors with guided microwave can be used.These
areunaectedbyfoamgenerationandarebestsuitedforsuchap-
plications.
Byusingastandpipe,theinuenceofvesselinstallationsandturbu-
lence can be excluded. Under these prerequisites, the measurement
of products with low dielectric constant (from 1.6) is possible.
Surge or bypass tubes must extend all the way down to the requested
min. level, as measurement is only possible within the tube.

When the sensor is mounted on a bypass tube, the distance from VE-
GAPULS 66 to the upper tube connection should be approx. 500 mm
(19.69 in) or more. In case of extremely rough tube inner walls, you
should use an inserted tube (tube in tube) or a radar sensor with tube
antenna.

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
Tip:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
In hazardous areas you must take note of the respective regulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
Supply voltage and current output are carried on separate two-wire
connection cables if reliable separation is required.The supply volt-
agerangecandierdependingontheinstrumentversion.
Thedataforpowersupplyarespeciedinchapter"Technical data".
The standard version can be operated with an earth-connected cur-
rentoutput,theExdversionmustbeoperatedwithaoatingoutput.
This instrument is designed in protection class I.To maintain this
protection class, it is absolutely necessary that the ground conductor
be connected to the internal ground terminal.Take note of the general
installation regulations.
Always connect the instrument to vessel ground (potential equalisa-
tion) or in case of plastic vessels to the next ground potential. For
this purpose there is a ground terminal on the side of the instrument
housing.
For power supply, an approved installation cable with PE conductor is
required.
The 4 … 20 mA current output is connected with standard two-wire
cable without screen. If electromagnetic interference is expected
which is above the test values of EN 61326 for industrial areas,

exchange the seal or use a suitable cable gland.
If screened cable is required, 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 on the
outside of the housing must be connected to the potential equalisa-
tion (low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low-frequency potential equalisation currents are thus
