6 Battery operation and power saving mode
PLICSMOBILE T61 • External GSM/GPRS radio unit
37700-EN-130228
The service life of the battery depends on many factors such as e.g.
the number of messages transmitted, sensor type, network quality
and temperature, so no exact time can be specified. With activated
power-saving mode with multidrop operation and 1 x measured
value transmission per day, a service life of approx. four years can be
expected.
Note:
If the Lithium power pack and the external voltage supply are used at
the same time, the power supply with the higher operating voltage is
tapped. When used together with the power pack, the external voltage
supply must have an operating voltage >18 V to be able to supply
power.
6.3 Accumulator pack
The accumulator pack was especially developed for the seamless
integration into the second housing chamber and is available from
VEGA under the article name "PM-AKKUAA". It consists of a holder
with six standard cell of the size AA (Mignon), six NiMH accumulators
and a regulator as well as a foam rubber sleeve for fastening in the
housing chamber.
Via the integrated charging electronics, the accumulators can be
charged via a power supply unit or a solar module (specifications see
"Technical data" in the supplement). The connection is carried out on
the terminals of PLICSMOBILE.
There are two slide switches and one LED indication on the upper
side of the accumulator pack.

•
Switch position On: PLICSMOBILE is powered, accumulators
are charged with external voltage supply (power supply unit/solar
module) and activated battery switch
•
Switch position OFF: PLICSMOBILE is not powered, accumula-
tors are charged with external voltage supply (power supply unit/
solar module) and activated battery switch
Generally, accumulators are inserted in the battery holder. If, as an
exception, non-chargeable batteries are to be used, the integrated
charge regulator must be switched off.
