3.2 Principle of operation
CNCR-130 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 through 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 according to DIN/EN/IEC/
ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
4.2 Mounting
A ceiling mounting bracket is a simple method of mounting the sensor. Take note of Figure 5 for
the recommended minimum distance to the vessel wall.
The simplest mounting of the device is on the ceiling.
Fig. 5: Ceiling mounting

CNCR-120/130 • Modbus and Levelmaster protocol 7
4.3 Mounting instructions
The radar emits pulses of electromagnetic waves which are polarized. By adjusting the rotation of
the instrument the polarization can be changed to reduce false echos.
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
reectionstominimizefalseechos,forexample,thesidewallorvesselstructure.
The position of the polarization is in the middle of the label on the instrument.
For the wall mounting, a mounting bracket with a 1.5” opening from BinMaster is recommended.
The sensor is secured in the mount using a 1.5” plastic counter nut. Take note of Figure 5 for the
recommended minimum distance to the vessel wall.

CNCR-120/130 • Modbus and Levelmaster protocol 8
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.
Fig. 8: Mounting of the radar sensor on round vessel tops
In vessels with cone bottoms, the sensor can be mounted in the center of the vessel to measure
material down to the outlet.

Fig. 11: Mounting of the radar sensor with inowing material
For socket or stand pipe mount, the pipe should be as short as possible and its end rounded to
reducefalsereectionsfromtheendofthepipe.
When using a threaded coupling, the antenna end should protrude at least 5 mm (0.2 in) out of
the coupling.
The lower side of the radar antenna is the reference plane for the min./max. adjustment, see the
following diagram.

100 mm 4” ≤400mm ≤15.8in
150 mm 6” ≤600mm ≤23.6in
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.
Ifthereectivepropertiesofthematerialaregood,youcanmountCNCR-130onsocketsor
stand pipes 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.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
•Electricalconnectionshouldbecompleted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.
The operating voltage and the digital bus signal are routed via separate two-wire connection cables.
Thedataforpowersupplyarespeciedinchapter“Technical data”.
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
Thedeviceissuppliedwithaxedcable.Ifanextensionisrequired,twistedtwo-wirecable
suitable for RS 485 should be used for the Modbus signal.
If electromagnetic interference is expected which is above the test values of EN 61326-1 for
industrial areas, shielded cable should be used.
MakesurethattheentireinstallationiscarriedoutaccordingtotheFieldbusspecication.In
particular, make sure that the bus is terminated with suitable terminating resistors.
We recommend to connect the cable shield to ground at one end on the supply side when
using shielded cable.

6 Setup with smartphone/tablet (Bluetooth)
6.1 Preparations
Make sure that your smartphone/tablet meets the following system requirements:
• Operating system: iOS 8 or newer
• Operating system: Android 5.1 or newer
• Bluetooth 4.0 LE or newer
DownloadtheWirelessDeviceConguratorappfromthe“Apple App Store” or “Google Play Store” to your
smartphone or tablet. To enable the Bluetooth software enter the BinMaster company ID code BMYQXZ.
6.2 Connecting
Start the adjustment app and select the function “Setup”. The smart-phone/tablet searches automatically for
Bluetooth-capable instruments in the area. The message “Connecting …” is displayed.
The devices found are listed and the search is automatically continued.
Select the requested instrument in the device list.
Whenestablishingtheconnectionforthersttime,thesmartphone/tabletandthesensormustauthenticate
eachother.Aftertherstcorrectauthentication,eachsubsequentconnectionismadewithoutanew
authentication query.
Forauthentication,enterthe6-digitBluetoothaccesscodeinthenextmenuwindow.Youcanndthecode
on the outside of the device housing and on the CNCR setup sheet enclosed in the device packaging.

Note:
If an incorrect code is entered, the code can only be entered again after a delay time and the delay gets
longer after each incorrect entry.
The message “Waiting for authentication” is displayed on the smart-phone/tablet.
After connection, the sensor adjustment menu is displayed on the smart-phone/tablet.
If the Bluetooth connection is interrupted, e.g. due to a too large distance between the two devices, this is
displayed on the adjustment tool. The message disappears when the connection is restored.
Parameter adjustment of the device is only possible if the parameter protection is deactivated, which is
default. Parameter protection can be activated later if desired.
6.3 Parameter adjustment
The sensor adjustment menu is divided into two areas, which are arranged next to each other or
one below the other, depending on the adjustment tool.
• Navigation section
• Menu item display
The selected menu item can be recognized by the color change.

Parameters for the bus communication
The CNCR-130 is preset with the following default values:
Startbitsanddatabitscannotbemodied.
General conguration of the host
Thedataexchangewithstatusandvariablesbetweenelddeviceandhostiscarriedoutviaregisters.
Forthis,acongurationinthehostisrequired.Floatingpointnumberswithshortprevision
(4 bytes) according to IEEE 754 are transmitted with individually selectable order of the data bytes
(byte transmission order). This “Byte transmission order” is determined in the parameter “Format
Code”. Hence the RTU knows the registers of the CNCR-130 which must be contacted for the
variables and status information.

11.3 Levelmaster commands
The CNCR-130 is also suitable for connection to the following RTUs with Levelmaster protocol.
The Levelmaster protocol is often called “Siemens” “Tank protocol”.
The Levelmaster commands are based on the following syntax:
•Capitallettersareatthebeginningofcertaindataelds
•Smalllettersstandfordataelds
• All commands are terminated with “<cr>” (carriage return)
• All commands start with “Uuu”, whereby “uu” stands for the address (00-31)
• “*” can be used as a wild card for any position in the address. The sensor always converts this in
its address. In case of more than one sensor, the wild card must not be used, because otherwise
several slaves will answer
• Commands that modify the instrument return the command with “OK“. “EE-ERROR” replaces
