spring rings according to DIN 217 or wedge lock washers according

to DIN 25 201.

Proceed as follows:

1. ClampVEGAPULS62withtheange,e.g.inabenchvice

2. Holdtheconnectionpiece(1)withawrenchontheatsurfaces

(widthacrossats22mm)

3. Loosen counter nut (3) completely with a wrench (width across

ats36mm)inthedirectionoftheantenna

4. Loosen compression nut (2) completely with a wrench (width

acrossats41mm)inthedirectionoftheantenna

5. Remove the parabolic antenna (4) axially

6. Mountsensorangeontheadapterange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 (SHS FPM 70C3

8. Remount the parabolic antenna (4)

9. Fastencompressionnut(2)withawrench(widthacrossats41),

On the version with rinsing air connection, make sure that the holes

intheantennaandintheprocessttingcoincide.Thisensuresasuf-

cientairow(theairisledthroughtheholestothefeedsystem.A

rinsing of the whole parabolic antenna is not intended).
