3.4 Before leaving the site
Note the installation height above the ground and the orientation of the wind meter, either on the cloud or on paper
to add afterwards.
Before leaving the site, ensure that all the devices are visible on the cloud and green and that connected wind
meters are also shown.
4 Maintenance
4.1 General
The device requires minimal maintenance. The currently provided MOx sensor technology does, however, have a
limited lifetime. When required to exchange the cartridge with a new factory calibrated spare, please follow the
steps below. Otherwise, the system does not require regular maintenance.
4.2 Cartridge replacement
Turn off the device before removing any cartridge. Ensure that the cable of the power source at the device side is
disconnected.
Using a Torx T7 screwdriver, unscrew the four screws securing the cartridge; then remove the cartridge in a clean
and dry space by pulling on the small plastic handles on the cartridge. While removing the cartridge, ensure that
the internal contacts of the device remain clean and dry. Loosen all four cartridge screws before attempting to
remove the cartridge. Afterwards, grab the external parts of the cartridge and pull the cartridge in the direction
opposite the direction of installation.
Insert the replacement cartridge into the now-empty slot. Insert the cartridge until you hear and feel it snap into
place. Fix the cartridge inside the device by tightening the integrated screws. These screws are intended to prevent
unwanted removal of the cartridge and to secure it in place.
Note: New cartridges do not require any extra calibration or configuration. The device and/or system will configure
the new cartridge automatically.
Caution
•
Always use the supplied blind cover to protect unused cartridge slots from
environmental influences.
•
Always disconnect the device from its power source before removing or installing
a cartridge to avoid damage to the device. It is important to disconnect the cable
from the device to power down the device correctly.
•
It is not necessary to tighten the screws of the cartridge strongly. Only tighten
the screws by hand and without excessive force to avoid wearing of the threads.
•
When removing the cartridge, only pull on the plastic parts. Never pull on the
connector as doing so might adversely influence the water ingress protection.
