1.2 Principle of operation
Application area
Functional principle
Voltage supply
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 p ower
supply via battery or 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 transitted via http to the visualisation software WEB-VV.
The use of the PLICSMOBILE is particularly suitable for inventory
management, VMI (Vendor Managed Inventory) and remote enquiry.
The PLICSMOBILE is a GSM/GPRS radio unit for
integrated in the second housing chamber of a plics
The internal radio unit PLICSMOBILE is
®
sensor. The
measured value recorded by the sensor is transferred via the I²C
interface to the PLICSMOBILE.
The transmission of measured values, event messages and diagnosis
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
connected sensor via remote parameter adjustment.
The voltage supply is provided via a standard low voltage (external
power supply unit/battery/accumulator). You can find detailed speci-
fications in chapters "Connecting to power supply" and "Technical
data".
If desired, PLICSMOBILE can also power the sensor electronics.
1.3 Operation
The adjustment is made via PACTware and the respective DTM by
using the integrated USB connection.

2 Mounting
2.1 General instructions
Information:
You can find the general mounting instructions in the operating
instructions manual of the respective sensor. The instructions listed
below are a supplement to that part of the radio module.
Mounting position
Check before mounting if there is sufficient coverage (signal strength)
by the chosen mobile phone provider at the planned location. This can
be simply tested with a mobile phone. Make sure the SIM cards in the
PLICSMOBILE and in the mobile phone are from the same mobile
phone provider. 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. As an option, an external
antenna with complete confectioned cable is available.
Select a mounting location where the instrument is within easy reach
for mounting and connecting as well as for the connection via USB. To
facilitate mounting, the housing can be rotated by 330° without the use
of any tools.
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.

3.1 Preparing the connection
Note:
You can find the general connection instructions in the operating
instructions manual of the respective sensor. The instructions listed
below are a supplement to that part of the radio module.
Keep in mind that when using PLICSMOBILE, no additional external
indication such as e.g. VEGADIS 61 can be connected.
3.2 Connection options
Voltage supply of sensor electronics and PLICSMOBILE can be
carried out in the following two ways:
Common power supply
of sensor electronics
and PLICSMOBILE
Separate power supply
of sensor electronics
and PLICSMOBILE
With this version, only one voltage supply for both electronics modules
is required. The voltage supply is connected to the PLICSMOBILE.
The sensor connection cable transmits, in addition to the measured
value, also the voltage supply of the sensor. Hence there is no
4 … 20 mA or Fieldbus signal from the sensor electronics available for
processing, e.g. via a PLC/control system. Hence, measured value
transmission can be only carried out via radio transmission through email/SMS/WEB-VV. Every sensor with integrated PLICSMOBILE is
shipped in this version.
With this version, the sensor electronics and the PLICSMOBILE are
each powered by a separate voltage supply. The measured values
can be transmitted via radio link and the 4 … 20 mA or Fieldbus signal
is also available for processing, for example via a PLC. If this version is
used, the internal connection cable must be separated and isolated at
the terminals of the sensor electronics. The blind stopper in the upper
housing chamber must be replaced by the included cable gland.
Connection of the sensor power supply is then carried out as
described in the respective operating instructions manual.
3.3 Connection steps PLICSMOBILE
The connection of PLICSMOBILE must be carried out in general
and is independent of the selected connection variant (separate or
common power supply).
Proceed as follows:
1 Unscrew housing cover of the lateral housing chamber
2 Loosen the compression nut of the cable gland on the left
3 Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
4 Insert the cable into the cable gland through the cable entry

5 Insert the wire ends into the terminals according to the wiring plan
Information:
Solid cores as well as flexible cores with cable end sleeves are
inserted directly into the terminal openings. In case of flexible cores
without end sleeves, press the terminal head with a small screwdriver;
the terminal opening is freed. When the screwdriver is released, the
terminal closes again.
6 Check the hold of the wires in the terminals by lightly pulling on
them
7 Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
8 Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
9 Screw the housing cover on
The electrical connection is finished.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When inserting t he terminal block again, you should
hear it snap in.

These steps must only be carried out if the sensor electronics is to be
powered via an additional voltage supply, for example, if the 4 … 20 mA
signal has to be evaluated.
Proceed as follows:
1 Unscrew housing cover of the upper housing chamber
2 Loosen and isolate the internal connection cable from the
terminals
3 Remove the blind stopper of the upper housing chamber
4 Insert the cable gland which is included in the delivery

4.1 Battery operation
PLICSMOBILE can be also powered via the battery. You can find
If no network-supported voltage supply is available,
detailed specification for voltage supply in chapter "Technical data".
The power saving mode should be switched on in battery operation
and time-controlled measured value transmission and the sensor
should be set to HART multidrop mode to increase the running time
(details se chapter "Power saving options").
4.2 Battery sizing
following points must be observed:
Power consumption in power saving mode:
If a battery or an accumulator is used which cannot be charged
cyclically, then the power saving mode should be activated. With an
operating voltage of e.g. 12 V, a standby power consumption of
0.3 mW must be taken into account. With an assumed lifetime of e.g.
one year, the requirement is approximately 2.6 Wh, which corresponds
to a battery capacity of 0.22 Ah at 12 V. The standby power
consumption with specific operating voltages is stated in the
"Technical data".
Power requirement complete measurement cycle incl. measured
value transmission:
A measurement cycle lasts approximately 60 to 120 seconds
(dependent 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, a power of
approximately 20 mWh is required. For example, with one measurement per day, this adds up to approx. 9.6 Wh per year, which
corresponds to a battery capacity of approx. 0.8 Ah at 12 V.

transmission cycles
