3.2 Principle of operation
VEGAPULS C 23 is a radar sensor for non-contact, 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medium
andreceivedbytheantennaasanechowithmodiedfrequency.The
frequency change is proportional to the distance and is converted into
the level.
3.3 Adjustment
Devices with integrated Bluetooth module can be adjusted wirelessly
via standard adjustment tools:
• Smartphone/tablet (iOS or Android operating system)
• PC/notebook with Bluetooth USB adapter (Windows operating
system)

3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter " Supplement -
Technical data - Ambient conditions"
• Relative humidity 20 … 85 %

4.1 General instructions
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences
4.2 Mounting versions
For the wall mounting, a mounting bracket with opening for thread G1
is recommended.The mounting of the device in the bracket is carried
out via the supplied G1 counter nut of plastic.Take note of chapter "
Mounting instructions" for the recommended distance to the wall.

4.3 Mounting instructions
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical wave compo-

nent. By turning the instrument in the mounting strap, the polarisation
canbeusedtoreducetheeectsoffalseechoes.
The position of the polarization is in the middle of the type plate on the
device or 90° to the logo.

When mounting the device, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the device is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can be suppressed by an appropriate adjustment (see chapter
" Setup").
If you cannot maintain this distance, you should carry out a false
signal suppression during setup.This applies particularly if buildup on
the vessel wall is expected. In such cases, we recommend repeating
the false signal suppression at a later date with existing buildup.

In vessels with conical bottom it can be advantageous to mount the
device in the centre of the vessel, as measurement is then possible
down to the bottom.

For nozzle mounting, the nozzle should be as short as possible and
itsendrounded.Thisreducesfalsereectionsfromthenozzle.
The antenna edge should protrude at least 5 mm (0.2 in) out of the
nozzle.
≥ 5 mm
(0.20")
Fig. 11: Recommended socket mounting of VEGAPULS C 23
Ifthereectivepropertiesofthemediumaregood,youcanmount
VEGAPULS C 23 on sockets longer than the antenna. The socket end
should be smooth and burr-free, if possible also rounded.
Note:
When mounting on longer nozzles, we recommend carrying out a
false signal suppression (see chapter " Parameter adjustment").
Youwillndrecommendedvaluesforsocketheightsinthefollowing
illustration or the table.The values come from typical applications.
Deviating from the proposed dimensions, also longer sockets are
possible, however the local conditions must be taken into account.

The mounting location of the radar sensor should be a place where no
otherequipmentorxturescrossthepathoftheradarsignals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a " clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.

In liquids, direct the device as perpendicular as possible to the me-
dium surface to achieve optimum measurement results.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion.This ensures that the
interferingreectionsfromtheagitatorsaresavedwiththebladesin
dierentpositions.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Carryoutelectricalconnectionbytrained,qualiedpersonnel
authorised by the plant operator
Warning:
Only connect or disconnect in de-energized state.
The operating voltage and the digital bus signal are routed via sepa-
rate 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)
acc. 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
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termi-
nated with suitable terminating resistors.
We recommend to connect the cable screening to ground potential at
one end on the supply side when using shielded cable.
