3.2 Principle of operation
The PLICSMOBILE T81 is a mobile network unit for transmission
of measured values and for remote parameter adjustment of plics®
sensors. Due to the large operating voltage range and the integrated
power saving functions, a mains-independent power supply via bat-
tery or accumulator/solar cells is possible. 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.vewithExversion).
The transmission of measured values, event messages and diagnos-
tic information to the user is carried out via the GSM/GPRS network.
Thanks to quadband technology, the device can be used virtually
anywhere in the world. There is also the option of accessing the con-
nected sensor via remote parameter adjustment.
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"Technical data".
The PLICSMOBILE T81 normally supplies power to the connected
sensors.
3.3 Adjustment
The device is adjusted via PACTware and the corresponding DTM.
The connection is made via the Bluetooth module integrated in
PLICSMOBILE T81.
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.

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.
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. If the radio reception is too weak, you
should search for a better position. In closed rooms this would be, for
example, close to a window or at least closer to an outer wall.
Note:
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.
Usetherecommendedcables(seechapter"Connecting to power
supply")andtightenthecablegland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cableentry.Rainandcondensationwatercanthusdraino.Thisap-
plies mainly to outdoor mounting as well as installation in areas where

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
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
requirements of EN IEC61010-1 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.
The sensor connection cable included in the delivery is used to con-
nect the sensor.
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).
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.
5.2 Connection options
Power can be supplied to the sensor and PLICSMOBILE in two ways:
With this version, only one voltage supply is required for both devices.
The voltage supply is connected to the PLICSMOBILE T81. In
addition to the measured value, the sensor connection cable also
carries the voltage supply of the sensor via HART. Hence there is
no 4 … 20 mA HART signal from the sensor electronics available for
processing, e.g. via a PLC. That's why the measured value transmis-

sion can only be carried out via radio transmission through e-mail/
SMS/VEGA Inventory System.
With this version, the sensor and the PLICSMOBILE T81 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 is available in parallel for processing, e.g. via a PLC.
HART communication
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cable.Thisresist-
ance is already integrated in PLICSMOBILE T81 and can be looped
automatically into the circuit by selecting the appropriate wires (see
wiring plan).
The connection to power supply is carried out as described in the
respective operating instructions manual.
5.3 Connection steps sensor connection cable
The sensor connection cable is used for transmission of the meas-
ured value from the sensor to the PLICSMOBILE T81. In addition, it
can also transmit the voltage supply for the connected sensor.
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.
To connect, proceed as follows:
1. Connect the colour coded wire ends to the respective sensor
terminals, as described in the wiring plan and the operating
instructions of the sensor.
2. Isolate unused wires, depending on connection type and cable
version
3. Connect the screen to the internal ground terminal, connect the
outer ground terminal on the housing to potential equalisation
4. Tighten the compression nut of the cable entry gland. The seal
ring must completely encircle the cable
5. Insert the plug of the sensor connection cable into the plug con-
nection on PLICSMOBILE T81
6. Tighten plug connection
5.4 Connection steps voltage supply
The connection of the voltage supply is made via spring-loaded termi-
nals in the electronics compartment. A small screwdriver is required

6 Battery operation and power saving mode
6.1 Battery/accumulator operation
If no mains voltage is available, PLICSMOBILE can be also powered
with batteries. For this purpose, an optional power pack is available
in a separate housing (PLICSMOBILE B81). This power pack can be
either ordered or equipped with chargeable accumulators or Lithium
batteries. As an alternative, an external battery/accumulator can be
connectedviathevoltagesupplyterminals.Youcannddetailed
informationofthevoltagesupplyinchapter"Technical data".
When battery/accumulator operation and time-controlled measure-
ment transmission are activated, the power saving mode should be
switchedonandtheBluetoothfunctionswitchedotoincreasethe
operatingtime(detailsseechapter"Power options").Inaddition,the
HART Multidrop mode should be switched on.
Note:
For charging the accumulators the ambient temperature must be in
a range of 0 … +45 °C (+32 … +113 °F). Temperatures outside this
range are permitted, however due to the protective circuit integrated
in the instrument, charging is not possible.
6.2 External battery PLICSMOBILE B81
The PLICSMOBILE B81 was especially developed for the power
supply of PLICSMOBILE T81. It can be optionally equipped with
rechargeable accumulators or non-rechargeable batteries of series
"D"(Mono).
Note:
ThereisasafetyinstructionleaetattachedtoeachPLICSMOBILE
B81 which must be read before setup and observed.
With the Ex version, one of the two following batteries/accumulators
must be used. If other batteries/accumulators are used, the approval
becomes invalid.
If there is no solar panel available at the installation location, then
PLICSMOBILE B81 should be equipped with non-chargeable Li-
batteries. As an alternative, standard Alkaline batteries can be used,
the lifetime is hence shorter. We recommend using Lithium batter-
iesLSH20ofMessrs.Saft(VEGAorderno.2.54970).Youcannd

willbedestroyedandtherewillbearehazard.
If a solar panel is used, PLICSMOBILE B81 must be equipped with
rechargeable NiMH accumulators. The solar panel is connected di-
rectly to terminals 4 and 5, a charge regulator is integrated in the bat-
tery cover. We recommend the use of NiMH accumulators 5030641

6.3 Solar panel PLICSMOBILE S81
Via the solar panel PLICSMOBILE S81 you can power the
PLICSMOBILE T81, the accumulator pack will also be charged. Two
solarpanelswithdierentsize/capacityareavailable:withasunny
environment and max. one measured value transmission per day, the
small5Wmoduleissucient;withintermittentshadowingand/or
more than one measured value transmission per day, the larger 20 W
module should be used. The technical data of both modules and the
order information can be found in the supplement of this instruction
manual.
Orient the solar module in such a way that in sunless seasons its
positionisidealtothesunandmaximumeciencyisachieved.Be-
cause in these seasons, the sun is very low, a steep installation angle
(approx. 60 - 75 degrees) is recommended so that the sunrays reach
the module at right angles. A tube holder suitable for the module is
available in the scope of delivery. The adjustment range of the inclina-
tion is 38 to 75 degrees, the orientation of the direction is individually
possible due to the tube mounted. As an option also a holder for
mounting on vertical surfaces such as walls is available.

Note:
The tube holder of the solar module is suitable for tube diameters of
30 … 60 mm (1.2 … 1.4 in). If the PLCSMOBILE should be mounted
to the same tube, a tube with ø 60 mm is required.
Fasten the PLICSMOBILE close to the solar module to avoid unnec-
essary voltage loss on the cable.

Note:
Make sure that the two cores of the connection cable are energized
when the solar module is already connected and not covered. Avoid
a short circuit during mounting and connection. Also pay attention to
this when shortening the cable, if that should be necessary.
6.4 Battery sizing
When selecting an external battery/accumulator, the following points
must be observed:
Power consumption in power saving mode:
If you use a battery or accumulator that cannot be automatically
recharged cyclically, the power saving mode should be activated.
With an operating voltage of e.g. 12 V, a standby power consumption
of 0.4 mW must be taken into account. With an assumed lifetime of
e.g. one year, the requirement is approximately 3.5 Wh, which cor-
responds to a battery capacity of 0.29 Ah at 12 V. The standby power
consumptionatspecicoperatingvoltagesisstatedinthe"Technical
data".
Power requirement for a complete measurement cycle incl.
measured value transmission:
A measurement cycle lasts approximately 60 to 120 seconds (de-
pendent on sensor type and network quality) and includes automatic
switching on of the sensor (HART multidrop mode with 4 mA),
recording of the measured value, measured value transmission and
a return to the power saving mode. During this time, approximately
15 mWh of energy is required. For example, with one measurement
per day, this adds up to approx. 7.3 Wh per year, which corresponds
to a battery capacity of approx. 0.6 Ah at 12 V.

Note:
Due to the nature of the system, each battery and accumulator has a
self-discharge which can vary considerably dependent on the type.
This is very important for the calculation of the required capacitance.
In the listed examples, this self-discharge is not taken into accunt. The
available capacitance depends also considerably from the tempera-
ture.Thespecicationsrefertoatemperatureof20°C(68°F).

IntheDTM(seechapter"Parameter adjustment with PACTware")
youcanselectunderthemenuitem"Energy options"betweenthe
modes"Continuous operation"and"Power saving mode".
In continuous (non-stop) operation PLICSMOBILE and the sensor
always remain switched on. Only in this mode can the instrument be
used for level monitoring and send an e-mail when a certain level is
reached or when an error occurs (measured value/status-controlled
transmission). In continuous operation PLICSMOBILE allows remote
parameteradjustmentviatheservicedepartment.Conguration
changes on PLICSMOBILE as well as the sensor can thus be carried
out remotely from any PC with PACTware via GPRS.
In this mode, the integrated GSM modem as well as the sensor
connected to PLICSMOBILE are switched on automatically when
the time-controlled transmission of a message is pending. After the
measured value is recorded, the log-in into the GSM network is car-
ried out and the measured value is transmitted. The instrument then
returns to power saving mode. The time for this process depends on
the network quality and is generally approx. 70 seconds.

Note:
Please note that event-controlled transmission (measured value/
status-controlled) is not possible in the power saving mode. A dial-in
connection for remote parameter adjustment is also not possible dur-
ing the inactive time.
When using battery operation and a HART sensor with non-required
4 … 20 mA signal, we recommend setting the sensor to multidrop
mode. In such case, the sensor consumes constantly only 4 mA
independently of the measured level, which increases the battery
life considerably. When connecting one or more sensors, the HART
multidrop mode is a basic requirement. A description of the activation
of multidrop mode can be found in the operating instructions of the
display and adjustment module.
With activated Bluetooth function, additional energy is needed; this
reduces the operating time with battery/accumulator operation con-
siderably.Forthatreason,switchotheBluetoothfunctionifitisnot

VEGA app for smartphones or tablets (iOS or Android) can be used.
In such case you can use the Bluetooth module already integrated in
the smartphone/tablet.
An activated SIM card (Mini-SIM) with data transmission option must
be used in PLICSMOBILE T81. The GSM/GPRS network must have
good coverage at the installation site.
Control elements on the device itself are limited to a test key and two
LEDs. With these, operational readiness and the status of the instru-
ment can be checked (connection to GSM network, standby …).

7.3 Parameter adjustment with PC and PACTware
For adjustment via Windows PC, a Bluetooth USB adapter and the
congurationsoftwarePACTwarewiththesuitableinstrumentdriver
(DTM) according to FDT standard are required. The up-to-date PACT-
ware version as well as all available DTMs are compiled in a DTM
Collection. The DTMs can also be integrated in other frame applica-
tions according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functionsareincludedinolderrmwareversions.Youcandownload
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
The basic operation of the software is described in the operating
instructionsmanual"DTM Collection/PACTware"attachedtoeach
DTM Collection and which can also be downloaded from the Internet.
Detailed descriptions are available in the online help of PACTware and
the DTMs.
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for

Saving/printing the project as well as import/export functions are also
part of the standard version.
In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.
The VEGA Bluetooth USB adapter is required for communication with
PLICSMOBILE T81. A Bluetooth module (possibly already installed
in the PC or notebook) or a USB adapter from another manufacturer
cannotbeused.Youcanndfurtherinformationintheinstructions

step, the parameter protection, the change of the instrument settings
can be blocked.
With activated Bluetooth access, connection to the instrument is
only possible if the respective Bluetooth access code is known. This
numerical access code (6-digit) is stored in the instrument and can
bereadoutandmodiedviaDTM.Inaddition,thecodeislistedin
the accompanying documents available in the scope of delivery. With
activated Bluetooth access, the access code must be entered only
once per adjustment tool because it is automatically stored with the
rstconnectiontotheadjustmenttool.
Information:
As a default setting, access protection is deactivated. To prevent from
unauthorized change of the instrument data, the Bluetooth access
protection and the following parameter protection should be activated.
As an alternative, the Bluetooth function can be deactivated via the
switch in the instrument.
Withparameterprotectionactivated,themodicationofdevice
parameters is blocked. By entering a numerical device code (four to
ten digits), the device is temporarily unlocked for a parameter change.
After 60 minutes without any adjustments being made, the instrument
is locked again automatically. Parameter protection is deactivated by
default.
7.4 Mobile network and SIM card
An activated SIM card (Mini-SIM format) with data transmission op-
tion is required for setup.
Information:
The SIM card does not belong to the standard scope of delivery of
the device. To avoid roaming costs, the card should be bought in the
country in which the PLICSMOBILE T81 is installed and operated. If
you are using a VEGA Ident Card, you don't have to worry about this
because no roaming costs are charged.
To make the measured value transmission and remote maintenance
assimpleaspossible,VEGAoerstheservicepackage"Wireless
data transmission".ThispackageincludesanIdentCard(SIMcardin
Mini-SIM format) that covers all data transmission costs and provides
worldwide 24-hour support.
Incoming data connections (PLICSMOBILE) can only be established
if the SIM card used supports GPRS. Incoming data connections are
used for remote parameter adjustment via VEGA service.
Information:
When the power saving mode is activated in PLICSMOBILE, it cannot
be contacted for remote parameter adjustment during the inactive
time. During the active time (during a data transmission), incoming
connections are accepted and maintained independent of the power
saving mode until the connection is terminated.

Data connections outgoing from PLICSMOBILE are established
via GPRS (volume-based billing). Outgoing connection are used
for measured value transmission via e-mail/SMS/VEGA Inventory
System.
During the transmission of the measured value via e-mail or Inventory
System, approximately 5 KB data are transmitted. With hourly trans-
mission, for example, this results in a monthly total net data volume of
approximately 4 MB.
The mobile network provider carries out a so-called block rounding
thatdependsontheselectedtari.WhencheckingoutoftheGPRS
network, the values are rounded to next higher billing units. Since
PLICSMOBILE checks out of the GPRS network after the transmis-
sion of every message (if the energy saving mode is activated),
this block rounding applies to each transmission. If, for example, a
tariwithblockroundingto100KBisused,anhourlymeasurement
transmission results in a monthly billing volume of over 70 MB. For
thatreason,youshouldchooseapuredatatariplan(M2M)withthe
lowest possible block rounding.
Insert the card (beveled side in front) into the card slot until it snaps in.
The contact surface must point upward.
Note:
The PLICSMOBILE T81 must be disconnected from voltage when
inserting the SIM card. Keep ESD protection in mind when handling
the SIM card. Electrostatic discharges can damage the SIM card or
the PLICSMOBILE.

8.1 Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
8.2 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.:
• Measured value from sensor not correct
• Voltage supply
• Interference in the cables
Therstmeasurestobetakenaretochecktheinput/outputsignalas
well as to evaluate the error messages via the DTM. The procedure is
described below. In many cases, the causes can be determined and
thefaultsrectiedinthisway.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.

9.1 Dismounting steps
Takenoteofchapters"Mounting"and"Connecting to power supply"
and carry out the listed steps in reverse order.
9.2 Disposal
The instrument consists of materials which can be recycled by spe-
cialised recycling companies. We use recyclable materials and have
designed the electronics to be easily separable.
Materials:seechapter"Technical data"
For disposal or recycling within the European Union proceed accord-
ingtothe"Electronics recycling"and"Battery/Accumulator recycling"
below. Outside the European Union you should take note of the valid
national regulations.
Electronics recycling
This instrument is not subject to the WEEE directive 2002/96/EG
and the respective national laws. Hence pass the instrument directly
on to a specialised recycling company and do not use the municipal
collecting points. These may be used only for privately used products
according to the WEEE directive.
Battery/accumulator recycling
Note:
The disposal is subject to the directive 2006/66/EG on batteries and
accumulators.
Batteries and accumulators contain some environmentally harm-
ful but also some valuable raw materials that can be recycled. For
that reason batteries and accumulators must not be disposed of in
household waste.
All users are legally obligated to bring spent batteries to a suitable
collection point, e.g. public collection points. You can also return the
batteries and accumulators to us for correct disposal. Due to the very
strict transport regulations for lithium-based batteries/accumulators,
this is normally not a good idea because shipment is very expensive.
Correctdisposalavoidsnegativeeectsonhumansandtheenviron-
ment and ensures recycling of useful raw materials.
