VEGA VEGAPULS 62 (≥ 2.0.0 - ≤ 3.8) Foundation Fieldbus - Manual (Page 16)

7 Check, if the O-ring seal is available on the connection piece and if
it is not damaged.
Note:
A damaged O-ring seal must be replaced: FKM (Viton) article no.
2.28248, FFKM (Kalrez 6375) article no. 2.27351
8 Remount the parabolic antenna (4)
9 Tighten compression nut (1) with SW 41, torque max. 50 Nm
10 Tighten locknut (2) with SW 36, torque max. 40 Nm.
Note:
Take note for VEGAPULS 62 with rinsing air connection that the holes
in the antenna and in the process fitting correspond. This ensures a
sufficient air 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
VEGAPULS
62 with horn antenna. The mounting instructions apply
analogously also to the version with parabolic antenna.
When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"S
etup").
