3.2 Principle of operation
CNCR-190 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
emittedsignalisreectedbythematerialandreceivedbytheantennaasanechowithamodied
frequency. The frequency change is proportional to the distance to the material.
3.3 Adjustment
Devices with integrated Bluetooth module can be adjusted wirelessly via software adjustment tools:
• Smartphone/tablet (iOS or Android operating system)
• PC/notebook with Bluetooth USB adapter (Windows operating system)

20 mA/HART can also be operated via a signal cable. This is done
via an interface adapter and a PC/notebook using DTM/PACTware.

4 Mounting
4.1 General instructions
The instrument is suitable for standard and extended ambient conditions according to DIN/EN/
IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
4.2 Mounting
For
the wall mounting, a mounting bracket with opening for thread G1 is recommended. The
sensor is mounted in the bracket using the supplied G1 plastic nut. Take note of Figure 4 for
the recommended distance to the wall.

4.3 Mounting instructions
The radar emits pulses of electromatic waves which are polarized. By adjusting 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 printed label on the instrument. This
should be pointed towards the center of the vessel or any obstacle that may cause any unwanted
reectiontominimizefalseechoes,forexamplethesidewallorvesselstructure.

When mounting the sensor, distance it at least 200 mm (7.874 in) from the vessel wall. If the sensor
is installed in the center of a round vessel top, multiple echoes can arise. However, these can be
suppressed by a false signal suppression (see chapter “Setup”).
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.
In vessels with cone bottoms, the sensor can be mounted in the center of the vessel to measure
material down to the outlet.

Ifthereectivepropertiesofthematerialaregood,youcanmounttheCNCR-190onsockets
or stand pipe longer than the antenna. The pipe end should be smooth, burr-free, and the end
rounded.
Note:
When mounting on longer sockets or stand pipes, we recommend carrying out a false signal
suppression after install (see chapter “Parameter adjustment”).
Recommended values for socket or stand pipe lengths and heights are in the following table.
The values come from typical applications.
For socket or stand pipe mount, the pipe should be as short as possible and its bottom end rounded
toreducefalsereectionsfromtheendofthepipe.
The antenna edge should protrude at least 5 mm (0.2 in) out of the socket or stand pipe.

The sensor should be mounted in a location where the radar signal is not interfered with by structure,
suchasladders,bracesorllstream.
Make sure when planning the installation there is a clear, unobstructed view to the material to be
measured.Afterinstallationafalsesignalsuppressionshouldbecarriedouttominimizeanyreections

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
•Carryoutelectricalconnectionbytrained,qualiedpersonnelauthorizedbytheplantoperator
• 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 according to UL1310)
• SELV power supply unit (safety extra-low voltage) with suitable internal or external limitation of the
output current
Thedeviceissuppliedwithaxedconnectedcable.Ifanextensionisrequired,astandardtwo-wire
cable can be used.
If electromagnetic interference is expected which is above the test values of EN 61326-1 for industrial
areas, shielded cable should be used.
Shielded cable generally necessary in HART multidrop mode.
We recommend to connect the cable screening to ground potential at one end on the supply side when
using shielded cable.
