3.2 Principle of operation
The PLICSMOBILE T81 is a mobile network unit for transmission of
measured values and for remote parameter adjustment of HART sen-
sors, especially of plics®sensors. Due to the large operating voltage
range and the integrated power saving functions, a mains-independ-
ent power supply via battery or accumulator/solar cells is possible,
for example through PLICSMOBILE B81.Typical applications are
measured value transmission from mobile vessels, battery-operated
level measurement and deep well measurement.
The measured value and message transmission can be optionally
carried out via e-mail or SMS. Furthermore, the measured values can
be transmitted via https for visualisation in "VEGA Inventory System".
The use of PLICSMOBILE T81 is particularly suitable for inventory
management,VMI(VendorManagedInventory)andremoteenquiry.
The external mobile network unit PLICSMOBILE T81 can be con-
nected to any 4 … 20 mA HART two-wire sensor of the plics®series.
In HART Multidrop operation up to 15 sensors can be connected to a
PLICSMOBILET81(max.5withExversion).
The transmission of measured values, event messages and diagnos-
tic information to the user is carried out via the GSM/GPRS/UMTS
network.Thank multi band technology, the device can be used virtu-
ally anywhere in the world. There is also the option of accessing the
connected sensor via remote parameter adjustment.
The combined radio antenna enables the GSM/GPRS/UMTS com-
munication as well as the Bluetooth connection. In addition, the
antenna enables the reception of position data via GPS.
Powerissuppliedviaastandardlowvoltagesource(externalpower
supplyunit/battery/accumulator/solarpanel)orviatheoptionally
availablePLICSMOBILEB81.Youcannddetailedspecicationson
the power supply in chapter "Connecting to power supply" as well as
in "Technical data".
3.3 Adjustment
The device is adjusted via a PC with PACTware and the corre-
sponding DTM or via smartphone/tablet with the VEGA Tools app.

4.1 General instructions
In the standard version, the PLICSMOBILE T81 is designed for
wallmounting.Mountingadaptersforcarrierrailmounting(tophat
rail35x7.5accordingtoDINEN50022/60715)aswellasfortube
mounting are optionally available.
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.
Makesurethattheenvironmentalandambientconditionsspeciedin
chapter "Technical data" are maintained.
Checkbeforemountingifasucientnetworkcoverage(signal
strength)ofthemobilenetworkproviderisavailableattheplanned
location. This can be simply tested by means of a mobile phone.
Keep in mind that the SIM cards in the PLICSMOBILE T81 and in the
mobile phone are from the same mobile phone provider or work in
the same mobile phone network.The PLICSMOBILE T81 supports
themobilephonestandards2G(GSM)and3G(UMTS).Themobile
phonestandard4G(LTE)howeverisnotsupported.Thereforeforthis
test of the network coverage, the 4G standard in the mobile phone
shouldbetemporarilyswitchedo.
If the radio reception is too weak, you should search for a better posi-
tion. In closed rooms this would be, for example, close to a window
or at least closer to an outer wall. In addition, an antenna extension
with magnetic base is available which can be placed up to 2.9 m away
from the instrument.
Caution:
During operation, a distance of at least 20 cm should be kept between
the antenna and persons working nearby. Operation of the instrument
with smaller distances is not recommended.
Protect your instrument against moisture ingress through the following
measures:
• Usetherecommendedconnectioncable(seechapter"Connect-
ing to power supply")
• Tighten the cable gland
• When mounting horizontally, turn the housing so that the cable
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where high
humidityisexpected(e.g.throughcleaningprocesses)andoncooled
or heated vessels.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Makesurethatthedegreeofcontaminationspeciedinchapter

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:
Connect only in the complete absence of line voltage.
Power can be supplied optionally via PLICSMOBILE B81 or a sepa-
rate power supply unit.
When using a power supply unit, the secondary circuit must be
separated from the primary circuit by double or reinforced insulation
(accordingtothenationallyvalidsafetystandards).
The air and creeping distances in PLICSMOBILE T81 meet the re-
quirements of EN IEC 61010-1 for secondary circuits with reinforced
insulationunderovervoltagecategoryIII(altitudeupto2000m).
The voltage supply of PLICSMOBILE T81 is connected with standard
cable according to the national installation standards.
If electromagnetic interference is expected which is above the test
values of EN 61326-1 for industrial areas, screened cable should be
used.
Make sure that the cable used has the required temperature resist-
anceandresafetyformax.occurringambienttemperature
We generally recommend the use of shielded cable for HART
multidrop mode.
Use cable with round cross section for instruments with housing and
cable gland. Use a cable gland suitable for the cable diameter to
ensurethesealeectofthecablegland(IPprotectionrating).
Connect the cable screen on the sensor side 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imped-
ance).
5.2 Connection options
Power can be supplied to the sensors and PLICSMOBILE in two
ways:
This version requires only one power supply for all devices. Up to
15 HART sensors can be connected to the PLICSMOBILE T81. The
power supply is connected to the PLICSMOBILE T81. In addition to
the measured value, the sensor connection cable also transmits the
power supply to all sensors via HART.

5 Connecting to power supply
PLICSMOBILE • Mobile network unit PLICSMOBILE T81
55234-EN-191217
With this version, the PLICSMOBILE T81 and a 4 … 20 mA/HART
sensors are each powered via a separate power supply. Here, the
measured values can be transmitted via radio communication and
the 4 … 20 mA HART signal of the sensor is available in parallel for
processing, e.g. via a PLC.
5.3 HART communication
If the sensors are connected to PLICSMOBILE, HART communica-
tion is ensured and no additional HART resistor must be looped.
If the internal resistance of the connected power supply for the sensor
islessthan230Ω,theHARTsignalisextremelydampedorshort-
circuited. Digital communication with PLICSCOM is then no longer
possible.With low impedance processing systems, a resistance of
approx.230Ωmustbeloopedintothe4…20mA/HARTcable.This
resistance is already integrated in PLICSMOBILE T81 and can be
looped automatically into the circuit by selecting the appropriate wires
(seewiringplanswithorwithoutHARTresistor).
The connection to power supply is carried out as described in the
respective operating instructions manual.
Note:
WhenconnectingmorethanoneHARTsensor,adierentaddress
mustbeassignedtoeachsensor(addressrange1-15).Address0
(mode4…20mA)maynotbeused.Whenassigninganaddress,
only one sensor should be connected to PLICSMOBILE T81. If con-
nectionisalreadycompleted,thewiringmustbebrieyundonefor
addressing. Depending on the installation location of the sensors, it
can be advantageous to carry out this addressing before installing
and connecting the sensors.This can be conveniently carried out
e.g. in the workshop.You only need a 24 Volt power supply as well as
an indicating and adjustment module PLICSCOM or the adjustment
software PACTware with VEGACONNECT.
The HART protocol enables the connection of up to two masters on
thesameline(Primary/SecondaryMaster).ThePLICSMOBILET81
works as Primary Master in the factory setting. If another master is to
be connected, e.g. for parameterization of the sensor, it must work as
a Secondary Master. If this is not possible, the PLICSMOBILE T81
canalternativelybereconguredasaSecondaryMaster.
5.4 Connection steps sensor connection cable
The sensor connection cable is used for transmission of the meas-
ured value from the sensors to the PLICSMOBILE T81. In addition, it
can also transmit the voltage supply for all connected sensors.
ThesensorconnectioncableisavailableinExversion(blue)
aswellasinnon-Exversion(black).Itcanbeorderedinthree
lengths(5/10/25m)andcanbeshortenedafterwardstoindividual
lengths. On one end there is a ready-for-use plug for connection to
PLICSMOBILE T81. On the other end are free cable ends for direct
connection to the sensor.
