5.2 Mechanical installation
Proper installation of the WEATHER STATION is carried
out using a tube socket R1½" (Ø 48.3mm) and at least
30mm in length. The inside diameter of the tube socket
must be at least 30mm as the electrical connection of the
WEATHER STATION is carried out at the bottom of the
device. After connection the WEATHER STATION is then
mounted on the tube or mast socket. The marking for
north on the device must be aligned to north (see section
4.2.1). The device is fixed to the shaft with the two Allen
screws (AF 4mm).
Caution:
The allen screws must be
tightened to 2Nm
5.2.1 Alignment to north
For exact determination of the wind and Brightness
direction the WEATHER STATION must be installed
aligned to
north
(true north).
When aligning the device, the
marking for north (N)
must point to
north
(true north). To do so, select a
conspicuous feature of the landscape to the north or
south with a compass and turn the mast or sensor until
the marking for north points to true north.
When aligning the device to north using a compass, bear
in mind the magnetic variation (= deviation in the
direction of the compass needle from true north) and
possible interference from magnetic fields (e.g. iron
parts, electric cables).
The lower edge of the sensor base is equipped with a
bore for north
aligned to the marking for north. This
bore allows a mast adapter with a pin for north to be
used here. The mast adapter is not included in the scope
of supply.
