6 Battery operation and power saving mode
PLICSMOBILE T81/B81/S81 • External GSM/GPRS/UMTS radio unit
55234-EN-170206
from Ansmann (VEGA ordering no. 2.54971). You can find further
information about this battery type in the 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 the
instrument, charging is not possible.
The battery cable joins PLICSMOBILE B81 with PLICSMOBILE T81.
It is available with 5/10/25 m length. Connect the cable as shown in
the wiring plan. Make sure that the terminals of both instruments are
connected 1 : 1 via this cable.
1. Make sure that the switch on the upper side of the cover is set to
"OFF"
2. Unscrew the central fixing screw with a coin. Then you can re-
move the battery cover.
3. Insert the four batteries/accumulators into the battery compart-
ment. The respective polarity is printed at the bottom of the
compartment but also in the battery cover.
4. Place back the battery cover to the battery compartment. Make
sure that the position is correct, the battery cover can only be at-
tached in one direction.
5. Push the battery cover slightly downward on the points marked
with "PUSH" and screw in the central fixing screw.
6. If all components are connected completely, you can set the
switch on the upper side of the battery cover to "ON"
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 different size/capacity are available: with a sunny
environment and max. one measured value transmission per day, the
small 5 W module is sufficient; 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 efficiency 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.
