9. Mounting the weather station
Close the housing by putting the cover back over the bottom part.
The cover must snap in on the left and right with a definite “click”.

Raste
Make sure the cover and bottom part are properly
snapped together! This picture is looking
at the closed sensor from underneath.

Push the housing from above into the fastened mount. The
bumps on the mount must snap into the rails in the housing.
To remove it, the weather station can be simply pulled upwards
out of the mount,against the resistance of the fastening.

11. Maintenance
The sensor must regularly be checked for dirt twice a year and
cleaned if necessary. In case of severe dirt, the sensor may not
work properly anymore.
!
As a precaution, the device should always be separated
from power supply for maintenance works (e.g. deacti-
vate or remove fuse).

10. Notes on mounting and commissioning
Do not open weather station if water (rain) might ingress: even
some drops might damage the electronic system.
Observe the correct connections. Incorrect connections may
destroy the weather station or connected electronic devices.
Please take care not to damage the temperature sensor (small
blank at the bottom part of the housing.) when mounting the
weather station. Please also take care not to break away or
bend the cable connection between the blank and the rain
sensor when connecting the weather station.
Remove all existing protection labels after installation.
The measured wind value and thus all other wind switching
outputs may only be supplied 60 seconds after the supply volt-
age has been connected.
After the auxiliary voltage has been applied, the device will en-
ter an initialisation phase lasting 5 seconds. During this phase
no information can be received via the bus.
Fig. 7
Place the sheath of the cable under the board and
allow only the connection cables through the holes
in the circuit board to the top.
Ensure that the sheath of the cable remains below the PCB
board and only the connection cables go through the rubber
seals on the bottom of the weather station and connect Voltage
and Bus +/- to the terminals provided.
