6 Battery operation and power saving mode
6.1 Battery/accumulator operation
If no mains voltage is available, PLICSMOBILE T81 can be also
powered with batteries. For this purpose, we recommend using
PLICSMOBILE B81. This battery housing can be either ordered or
equipped with chargeable accumulators or not rechargeable Lithium
batteries. As an alternative, an external battery/accumulator can be
connected via the voltage supply terminals. You can find 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 off to increase the
operating time (details see chapter "
Power options
"). In addition, the
HART Multidrop mode should be switched on in the sensor.
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).
Caution:
There is a safety instruction leaflet attached to each PLICSMOBILE
B81 which must be read before setup and observed.
If there is no solar panel available at the installation location, then
PLICSMOBILE B81 should be equipped with non-chargeable Lithium
batteries. As an alternative, standard Alkaline batteries can be used,
the lifetime is hence shorter. We recommend using Lithium batteries
LSH 20 of Messrs. Saft which are available in many standard online
shops. You can find further information in chapter "
Technical data
".
Warning:
When using non-chargeable batteries, the terminals of the "
Solar
Panel Input
" must not be connected. If voltage is applied, the batteries
will be destroyed and there will be a fire hazard.
If a solar panel is used, PLICSMOBILE B81 must be equipped with
rechargeable NiMH accumulators. The solar panel is connected
directly to terminals 4 and 5, a charge regulator is integrated in the
battery cover of PLICSMOBILE B81. We recommend the use of NiMH
accumulators 5030641 from Ansmann which are available in many
standard online shops. You can find further information of this battery
type in chapter "
Technical data
".
Note:
For charging the accumulators the 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
PLICSMOBILE B81, charging is not possible.
