VEGAPULS 68 • 4 … 20 mA/HART - four-wire
51905-EN-180222
1. Clamp VEGAPULS 68 with the flange, e.g. in a bench vice
2. Hold the connection piece (3) with a wrench (spanner size 22) on
the flattenings
3. Loosen counter nut (2) with spanner size 36 completely in the
direction antenna
4. Loosen compression nut (1) with a wrench SW 41 completely in
the direction of the antenna
5. Remove the parabolic antenna (4) axially
6. Mount sensor flange on the adapter flange and fasten it tightly
7. Check if the O-ring seal is present on the connection piece and
make sure it is not damaged.
Note:
A damaged O-ring seal must be replaced: FKM 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 counter nut (2) with SW 36, torque max. 40 Nm.
Note:
Take note for VEGAPULS 68 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).
