3.2 Principle of operation
VEGATRENN 141 is an [EEx ia] separator with separate power sup-
ply for connection of 4 … 20 mA/HART sensors in two-wire version.
As an associated electrical device, it ensures a galvanic separation
between sensor circuit and processing circuit and thus between Ex
and non-Ex areas.
An integrated transmitter power supply powers the connected sensor.
The current signal from the sensor (4 … 20 mA) is transferred to the
output linearly and galvanically separated. The instrument is HART
transparent, i.e. the HART signals are transmitted bidirectionally
between input and output.
Wide range power supply with a nominal voltage of 24 … 230 V AC
50/60Hzor24…65VDC.

Detailed information about the power supply can be found in chapter
"Technical data".
3.3 Operation
NoadjustmentorcongurationofVEGATRENN141isnecessary.A
parameter adjustment of the connected sensors can be carried out
via the HART communication sockets behind the hinged front cover.
Adjustment of the connected sensors is carried out preferably via a
Windows PC with a parameter adjustment software such as PACT-
ware and corresponding DTM. A VEGACONNECT interface converter
or a HART modem is necessary for connecting the PC.
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 of standard instruments consists of environment-
friendly, recyclable cardboard. 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 Mounting
4.1 Mounting instructions
VEGATRENN 141 is designed for carrier rail mounting (top hat rail
35 x 7.5 according to DIN EN 50022/60715). Due to its protection
rating of IP 20, the instrument is suitable for mounting in switching
cabinets.Itcanbemountedhorizontallyandvertically.
Note:
When several instruments are mounted together without space in
between, the ambient temperature at the installation location of the
instrument must not exceed 60 °C. Around the ventilation slots there
must be a distance of at least 2 cm to the next component.
VEGATRENN 141 is a corresponding, intrinsically safe equipment
andmustnotbeinstalledinhazardousareas.Asafeoperationisonly
ensurediftheoperatinginstructionsandEGtypeapprovalcerticate
are observed.VEGATRENN 141 must not be opened.
A distance of 50 mm to the intrinsically safe terminals must be en-
sured when mounting.

VEGATRENN 141 • 4 … 20 mA/HART
52239-EN-160229
5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed
Inhazardousareasyoumusttakenoteoftherespectiveregulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
The nominal range of the voltage supply can be 24 … 230 V AC
50/60Hzor24…65VDC.Youcannddetailsonthevoltagesupply
in the technical data.
The voltage supply of VEGATRENN 141 is connected with standard
cable according to the national installation standards.
The sensors are connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should
be used. In general, cable screening is necessary in HART multidrop
mode.
Connect the cable screen on both ends to ground potential. In the
sensor, the screen must be connected directly to the internal ground
terminal. The ground terminal on the outside of the sensor housing
must be connected to the potential equalisation (low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low-frequency potential equalisation currents are thus
suppressed,buttheprotectiveeectagainsthighfrequencyinterfer-
ence signals remains.
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
owoverthecablescreen.Incaseofgroundingonbothsidesthis
can be achieved by the use of a capacitor or a separate potential
equalisation.
The instrument is equipped with communication sockets in the front
for connection of a VEGACONNECT or another HART handheld as
well as an integrated HART resistor.
If the resistance of the connected processing system is less than
230Ω,thedigitaladjustmentsignalisextremelydampedorshort-cir-
cuited. Digital communication with the PC is then no longer possible.
Withlowimpedanceprocessingsystems,aresistorofapprox.230Ω
must be looped into the 4 … 20 mA cable.This resistor is already inte-
grated in VEGATRENN 141 and can be chosen through the selection
of the respective terminals.

5 Connecting to power supply
VEGATRENN 141 • 4 … 20 mA/HART
52239-EN-160229
In HART multidrop mode, the measured values are transmitted
on the same cable (bus) as the digital HART signals. An analogue
4 … 20 mA transmission is not possible, the current is limited to 4 mA.
An own, unambiguous address (address range 1-15) must be as-
signedtoeachconnectedsensor.Inthismode,uptovesensorscan
be connected to one channel.
5.2 Connection procedure
The pluggable terminals can be removed as needed to allow more
convenient connection.To make the electrical connection, proceed as
follows:
1. Mount the instrument as described in the previous chapter
2. Connect sensor cable to terminal 1/2, and where applicable, con-
nect the screen
3. Connectpowersupply(switchedo)toterminal16/17
4. Connect processing circuit, e.g. from PLC to terminal 11/12 or
10/12 (with HART resistor), and screen, if necessary
Theelectricalconnectionisnished.
Note:
If several sensors should be connected in HART multidrop mode, a
respective HART address must be assigned to each sensor before
connecting to VEGATRENN 141.

7 Maintenanceandfaultrectication
7.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
7.2 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Maximum reliability is ensured. Nevertheless, faults can occur during
operation.These may be caused by the following, e.g.:
• Voltage supply
• Interference in the cables
Therstmeasuretobetakenistochecktheinput/outputsignalas
well as the power supply. In many cases, the causes can be deter-
minedandfaultscanbequicklyrectied.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. [phone].
Thehotlineismanned7daysaweekround-the-clock.Sinceweoer
this service worldwide, the support is only available in the English
language.The service is free, only standard call charges are incurred.
Depending on the reason for the fault and the measures taken, the
steps described in chapter "Set up" may have to be carried out again.
