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
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.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
4.2 Mounting instructions
The measuring range of the VEGAPULS 42 physically begins with the
antenna end.
However, the min./max. adjustment begins mathematically with the
referenceplane,whichislocateddierentlydependingonthesensor

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
" Set up").
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.

Note:
When mounting on longer nozzles, we recommend carrying out a
false signal suppression (see chapter " Parameter adjustment").
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.

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
(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault
signal)
• 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.
Depending on the connection method or signal output, the device is

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 with Bluetooth. In addition, it is supplied with
the device in the information sheet " PINs and Codes" In addition, the
Bluetooth access code can be read out via the display and adjust-
ment unit, depending on the device version.
TheBluetoothaccesscodecanbechangedbytheuseraftertherst
connection is established. If the Bluetooth access code is entered
incorrectly, the new entry is only possible after a waiting period has
elapsed. The waiting time increases with each further 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
access code, it must be re-entered for each unlock.When using the
adjustment app or DTM, the stored device code is then suggested to
the user for unlocking.
The emergency device code allows unlocking the device in case the
device code is no longer known. It can't be changed. The emergency
device code can also be found on the supplied information sheet " Ac-
cess protection". If this document is lost, the emergency device code
can be retrieved from your personal contact person after legitimation.

The storage and transmission of the device codes is always encrypt-
ed (SHA 256 algorithm).
6.3 Storing the codes in myVEGA
If the user has a " myVEGA" account, then the Bluetooth access code
as well as the device code are additionally stored in his account under
" PINs and Codes".Thisgreatlysimpliestheuseofadditionaladjust-
