9.2 Troubleshooting
9.2.1 Cleaning
If you check the system status and notice that the solar efficiency of a device drops
significantly, this may be due to contamination of the solar cells. Especially with the TMSO.IM,
which act as base sensors and are therefore installed close to the ground, this can quickly
happen due to falling leaves, snow or soil splashed by heavy rain.
As long as the battery has enough remaining charge this is not an urgent problem.
Just remember to check the equipment at the next regular site visit and remove leaves or the
like. You can also wipe the solar cells with a handkerchief.
9.2.2 Charging the TMSO.CU on Site
The TMSO.CU is usually charged by the solar cell on site. If this supply is not sufficient and
the battery charge level drops too low, it is also possible to recharge the device on site via the
USB interface during operation.
For this purpose the TMSO.CU must be connected via the USB cable to an appropriate USB
charger (like the one supplied) or a standard 10 Ah power bank. The charging process is
indicated by a slowly blinking
CHARGE LED.
When the battery is fully charged, the LED lights
up continuously.
For safety reasons only a low charge current is used in this operating state. In order to achieve
a significant effect, a time of several hours must therefore be allowed.
