8 Remount the parabolic antenna (4)
9 Fasten compression nut (1) with a wrench (width across flats 41),
torque max. 50 Nm
10 Fasten counter nut (2) with a wrench (width across flats 36), torque
max. 40 Nm
Note:
Take note for the version with rinsing air connection that the holes in
the antenna and in the process fitting correspond. This ensures a
sufficient a ir flow (the air is led through the holes to the feed system. A
rinsing of the parabolic antenna in total is not intended).

4.4 Mounting instructions
The illustrations with the following mounting instructions show a radar
sensor with horn antenna. The mounting instructions apply analo-
gously also to the version with parabolic antenna.
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation level is the direction of the electrical wave
component. By turning the instrument in the connection flange or
mounting boss, the polarisation can be used to reduce the effects of
false echoes.
The position of the polarisation plane is marked on the process fitting
of the instrument.
