3.2 Principle of operation
CNCR-230 is a radar sensor for continuous level measurement. It is suitable for liquids and
solids in practically all industries.
The instrument emits a continuous, frequency-modulated radar signal from its antenna. The
emittedsignalisreectedbythematerialandreceivedbytheantennaasanechowithmodied
frequency. The frequency change is proportional to the distance to the material.

4.1 General instructions
The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/
ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
Protect your instrument against moisture ingress through the following measures:
• Use a suitable connection cable
•Tightenthecableglandorplugconnectorrmly
• Face the connection cable or conduit entry downward, never upward
This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through
cleaning processes) and on cooled or heated vessels.

CNCR-230 • Two-wire 4 - 20 mA/HART 7
4.2 Mounting instructions
The radar emits pulses of electromagmetic waves which are polarized. By adjusting the rotation of
the instrument the polarization can be changed to reduce false echoes.
The narrow portion of the radar signal is in the middle of the conduit entry on the instrument. This
should be pointed towards the center of the vessel or any obstacle that may cause any unwanted
reectionstominimizefalseechos,forexample,thesidewallorvesselstructure.
Fig. 4: Polarization Position
1. Cable conduit entry/vent
The lower side of the radar antenna is the beginning of the measuring range. It is at the same time
the reference plane for the min./max. adjustment, see following diagram:
When mounting the sensor, keep a distanceofatleast200mm(7.874in)from the vessel wall. If the
sensor is installed in the center of a round top vessel, multiple echoes can arise. However, these can
be suppressed by a false signal suppression (see chapter “Set up”).
Fig. 5: Reference plane
1. Reference plane

CNCR-230 • Two-wire 4 - 20 mA/HART 8
In vessels with cone bottoms, the sensor can be mounted in the center of the vessel
to measure material down to the outlet.
Fig.7:Mountingtheradarsensorwithconicalbottom
Fig.6:Mountingtheradarsensoronroundvesseltops
If you cannot maintain this distance, you should carry out a false signal suppression during initial
setup. This applies particularly if buildup on the vessel wall is expected. If this is the case, we
recommend repeating the false signal suppression later with the additional buildup.
Donotmounttheinstrumentsinorabovethellingstream.Makesurethatyoudetectthematerial
surface,notthellstream.

CNCR-230 • Two-wire 4 - 20 mA/HART 9
When using a threaded coupling, the antenna end should protrude at least 5 mm (0.2 in) out
of the socket.
Fig.8:Mountingtheradarsensorawayfromthellstream.
Fig. 9: Thread mounting
Ifthereectivepropertiesofthemediumaregood,youcanmountCNCR-230onsocketsor
stand pipes longer than the antenna. The pipe end should be smooth, burr-free, and the end
rounded.
Recommended values for socket or stand pipe lengths and heights are in the following table.
The values come from typical applications.

100 mm 4” ≤400mm ≤15.8in
150 mm 6” ≤600mm ≤23.6in
Note:
The sensor should be mounted in a location where the radar signal is not interfered with by
structure,suchasladders,bracesorllstream.
Make sure when planning the installation there is a clear, unobstructed view to the material to
be measured. After installation a false signal suppression should be carried out to minimize
anyreectionsfromthemountornearbystructure.
5 Connecting to power supply
5.1 Preparing the connection
•Carryoutelectricalconnectionbytrained,qualiedpersonnelauthorizedbytheplantoperator
• If overvoltage surges are expected, overvoltage arresters should be installed
Warning:
Only connect or disconnect in de-energized state.
Note:
Power the instrument via an energy-limited circuit (power max. 100 W) according to IEC 61010-1, e.g.
• Class 2 power supply unit (acc. to UL1310)
• SELV power supply unit (safety extra-low voltage) with suitable internal or external limitation
of the output current
Useroundcabletoensuree󰀨ectivesealingofthecableglandtotheappropriateIPratingand
checkthecablediameterversusthecableglandbeforewiringforpropert.
The instrument is connected with standard two-wire cable. If electromagnetic interference is
expected which is above the test values of EN 61326-1 for industrial areas, shielded cable
should be used.

CNCR-230 • Two-wire 4 - 20 mA/HART 11
Note:
Shielded cable generally necessary in HART multidrop mode.
Note:
If the temperatures are too high, the cable insulation can be damaged.
We recommend connecting the cable screening to ground potential at one end on the supply side
when using shielded cable.

e.g. via a measuring plate
In this menu item you select the unit for measured distance in mm, m, in or ft.
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.

CNCR-230 • Two-wire 4 - 20 mA/HART 20
To perform the adjustment, enter the distance with full and empty vessel, see the following example:
Fig.16:Parameterexample,Min./max.adjustment

2.Max.level=min.measuringdistance
3. Reference plane
6.4.2 Extended Functions
In the menu item “Display value”youdenetheindicationofthemeasuredvaluesontheindicationas
llingheight,distance,percent,lin.percentorscaled.
In the menu item “Scaling”youdenehowthelevelvalueisshownontheindication.Thisincludesthe
scaling size, unit and format as well as the assignment to 0% and 100% of the measured value.
Scaling makes it possible, for example, to display the volume in m³.
Thestartingpointforthesedistancespecicationsisalwaysthereferenceplane,i.e.theloweredgeof
the sensor. Information on the reference plane can be found in the chapters “Mounting” and “Technical
data”.Theactualllingheightisthencalculatedonthebasisoftheseentries.
The actual 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.
