5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
• The electrical connection must only be carried out 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".
The voltage supply is connected with standard cable according to the
national installation standards.
Standard two-wire cable can be used to connect the sensors.
Note:
If the temperatures are too high, the cable insulation can be dam-
aged. Hence keep apart from the ambient temperature also the self-
heating of the instrument for the temperature resistance of the cable
in the connection compartment in mind. 1)
When used in the USA/Canada, only cables with copper conductors
may be used.
5.2 Sensor input mode active/passive
Through the selection of the terminals, you can choose between ac-
tive and passive operation of the sensor input.
• In active mode, the controller provides the power for the con-
nected sensors. Power and measurement data are transmitted
over the same two-wire cable.This mode is provided for connec-
tion of measuring transducers without separate power supply
(sensors in two-wire version).
• In passive mode the sensors are not powered, only the measured
value is transmitted. This input is for connection of transmitters
with their own separate voltage supply (sensors in four-wire ver-
sion).The VEGAMET 342 can also be looped into the existing
circuit like a normal ammeter.
Note:
With a VEGAMET 342 in Ex version, the passive input is not available.
5.3 Connecting
The power supply and the inputs and outputs are connected via
removablescrewterminals.Youcanndinformationonthemax.wire

6 Access protection
VEGAMET 342 • 4 … 20 mA
63731-EN-221107
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.
Information:
If no Bluetooth connection to the device should be possible, Bluetooth
communication can be deactivated. Access via app or DTM is thus no
longer possible.The Bluetooth function can be deactivated/activated
in the menu item " Extended functions" under " Access protection -
Bluetooth communication".
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
information sheet " PINs and Codes".The Bluetooth access code can
also be read out via the display and adjustment unit.
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.

VEGAMET 342 • 4 … 20 mA
63731-EN-221107
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-
ment tools, as all Bluetooth access and device codes are automati-
cally synchronized when connected to the " myVEGA" account

Via the HART communication sockets integrated in the terminals, a
parameter adjustment of the connected HART sensors can be carried
out without interrupting the measuring circuit.The resistor required
forthispurpose(230Ω)isalreadyintegratedinVEGAMET342.The
sockets have an inner diameter of 2 mm for direct connection of a
VEGACONNECT or other HART modems. The adjustment of the con-
nected sensor is carried out via the VEGA Tools app or via PACTware
and appropriate DTM.

7.4 Setup steps
Through parameter adjustment, the instrument is adapted to the
individual application conditions. A measurement loop calibration is
the most important step and should always be carried out. A scaling
of the measured value to the desired physical variable and unit, pos-
sibly including a linearization curve, is often useful. The adaptation of
the relay switching points or the setting of a damping to smooth the
measured value are further standard adjustment options.
Information:
When using PACTware and the respective DTM or the VEGA Tools
app, additional settings can be carried out which are not possible or
only partly possible with the integrated display and adjustment unit.
Communication takes place via the built-in Bluetooth interface.
