VEGAPOINT 21 • Transistor (NPN/PNP)
56623-EN-210210
It is designed for industrial use in all areas of process technology and
can be used in water-based liquids.
Typicalapplicationsareoverllanddryrunprotection.Withathe
small sensor unit, VEGAPOINT 21 can be also mounted e.g. in thin
pipelines.The sensor allows use in vessels, tanks and pipes. Thanks
to its simple and robust measuring system, VEGAPOINT 21 is virtu-
allyunaectedbythechemicalandphysicalpropertiesoftheliquid.
Italsoworksunderdicultmeasuringconditionssuchasturbulence,
air bubbles, strong external vibrations or changing media. In addition,
the sensor can also detect foam.
Function monitoring
The electronics module of VEGAPOINT 21 continuously monitors the
following criteria via frequency generation:
• Failure of the signal generation
• Line break to the sensor element
If a malfunction is detected or in case of voltage supply, the electron-
icstakesonadenedswitchingstatus,i.e.theoutputisopen(safe
state).
Analternatingelectriceldisgeneratedatthetipofthemeasur-
ing electrode. If the sensor is covered with medium, the resonance
frequency changes.This change is detected by the electronics and
converted into a switching command.
Buildupisignoredtoacertaindegreeandthereforehasnoinuence
on the measurement.
3.3 Adjustment
The switching status of VEGAPOINT 21 can be checked from outside
(LED illuminated ring).
The optionally integrated Bluetooth module enables in addition a wire-
less adjustment of VEGAPOINT 21.
This is done via standard operating devices:
• Smartphone/tablet (iOS or Android operating system)
• PC/notebook with Bluetooth LE or Bluetooth USB adapter (Win-
dows 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

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
The VEGAPOINT 21 can be mounted in any position.The instrument
must be mounted in such a way that the sensor is at the height of the
requested switching point.

VEGAPOINT 21 • Transistor (NPN/PNP)
56623-EN-210210
Note that the switching point varies depending on the type of medium
and the mounting position of the sensor.
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
The level switch is a measuring device for stationary screw mounting
and must be treated accordingly. Damage to the measuring tip will
destroy the instrument.
Use the hexagon above the thread for screwing in.
Aftermounting,makesurethattheprocessttingisscrewedincor-
rectly and thus securely seals even at maximum process pressure.
4.2 Mounting instructions
In adhesive and viscous media, the surfaces of the sensor should
protrude into the vessel to avoid buildup.Therefore mounting bosses
should not exceed a certain length.
Fig. 5: Adhesive products
In horizontal pipelines, avoid mounting in the upper or lower area of
the pipe.
In the upper part of the pipe cavities can form due to air inclusions.
Solids can settle in the lower pipe area. Both can lead to measure-
ment errors.
In horizontal pipelines, lateral installation is therefore recommended.

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
• If overvoltage surges are expected, overvoltage arresters should
be installed
Warning:
Only connect or disconnect in de-energized state.
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
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Lower output voltage of the power supply unit under nominal load
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
chapter " Technical data")
Use cable with round cross section. Depending on the plug connec-
tion, you have to select the outer diameter of the cable respectively so
thatthesealeectofthecableglandisensured.
The instrument is connected with standard four-wire cable. If electro-
magnetic interference is expected which is above the test values of
EN 61326-1 for industrial areas, shielded cable should be used.

6 Access protection
VEGAPOINT 21 • Transistor (NPN/PNP)
56623-EN-210210
6 Access protection
6.1 Bluetooth radio interface
Devices with a Bluetooth radio interface are protected against un-
wanted access from outside.This means that only authorized persons
can receive measured and status values and change device settings
via this interface.
A Bluetooth access code is required to establish Bluetooth com-
munication via the adjustment tool (smartphone/tablet/notebook).
This code must be entered once when Bluetooth communication is
establishedforthersttimeintheadjustmenttool.Itisthenstoredin
the adjustment tool and does not have to be entered again.
The Bluetooth access code is individual for each device. It is printed
on the device housing and is also supplied with the device in the infor-
mation sheet " PINs and Codes". It can be changed by the user after
therstconnectionhasbeenestablished.IftheBluetoothaccess
code has not been entered correctly, a new entry can only be made
after a waiting period has elapsed.The waiting time increases with
each additional incorrect entry.
The emergency Bluetooth access code enables Bluetooth communi-
cation to be established in the event that the Bluetooth access code
is no longer known. It can't be changed. The emergency Bluetooth
access code can be found in information sheet " Access protection".
If this document is lost, the emergency Bluetooth access code can
be retrieved from your personal contact person after legitimation.
The storage and transmission of Bluetooth access codes is always
encrypted (SHA 256 algorithm).
6.2 Protection of the parameterization
The settings (parameters) of the device can be protected against un-
wanted changes. The parameter protection is deactivated on delivery,
all settings can be made.
To protect the parameterization, the device can be locked by the user
with the aid of a freely selectable device code. The settings (param-
eters) can then only be read out, but not changed.The device code
is also stored in the adjustment tool. However, unlike the Bluetooth

The emergency device code allows unlocking the device in case the
device code is no longer known. It can't be changed. The emergency

ed (SHA 256 algorithm).
