Mounting
18
Der VEGAPULS 62 is also available in versions where the
antenna has a bigger diameter than the process fitting (thread,
flange). The antenna must therefore be disconnected from the
flange before mounting. Proceed as follows:
1 Clamp VEGAPULS 62 with the flange, e.g. in a bench vice
2 Hold the connection piece (3) with a wrench SW 22 on the
flattenings
3 Unscrew the locknut (2) with SW 36 against the antenna
4 Loosen compression nut (1) with a screwdriver SW 41
completely in the direction of the antenna
5 Remove the parabolic antenna (4) axially
6 Mount sensor flange to the adapter flange and clamp it
7 Check, if the O-ring seal is available on the adapter and if it
is not damaged.
Note:
A damaged O-ring seal must be replaced: FKM (Viton) article
no. 2.28248, Kalrez 6375 article no. 2.27351
8 Remount the parabolic antenna (4)
9 Tighten compression nut (3) 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).
