be carried out only by trained specialist personnel authorised by the
plant operator.
During work on and with the device the required personal protective
equipment must always be worn.
1.2 Appropriate use
VEGAPULS SR 68 is a sensor for continuous level measurement.
Youcannddetailedinformationabouttheareaofapplicationin
chapter "Product description".
Operational reliability is ensured only if the instrument is properly
usedaccordingtothespecicationsintheoperatinginstructions
manual as well as possible supplementary instructions.
1.3 Warning about incorrect use
Inappropriate or incorrect use of the instrument can give rise to
application-specichazards,e.g.vesseloverllordamagetosystem
components through incorrect mounting or adjustment.
1.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and guidelines. The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsible

3.1 Mounting preparations - Parabolic antenna
The instrument is also available in versions where the antenna has
adiameterlargerthantheprocesstting(thread,ange).Withsuch
versionstheantennamustbedisconnectedfromtheprocesstting
before mounting. Proceed as follows:
1. ClampVEGAPULSSR68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
GLT),FFKM(Kalrez6375)
8. Remount the parabolic antenna (4)
9. Fastencompressionnut(2)withawrench(widthacrossats41),
torquemax.50Nm
10. Fastencounternut(3)withawrench(widthacrossats36),
torquemax.40Nm
Note:
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).

3.2 Mounting preparations - Horn antenna
The instrument is also available in versions with an antenna whose
diameterislargerthantheprocesstting(thread,ange).Insuch
casestheantennamustbedisconnectedfromtheprocesstting
before mounting. Proceed as follows:
1. Loosenthehexagonsocketscrews(3)ontheantennasocket
withanAllenwrench(size3)
2. Remove the antenna (4)
Note:
The plastic cone may not be pulled out of the antenna socket.
3. Insert the antenna from below into the vessel socket and secure it
againstfallingo
4. Retightentheantennawithhexagonscrewstotheantenna
socket;torquemax.2.5Nm(1.8lbfft)
Note:
Theradarsensorwithrinsingairconnectionorantennaextension
is provided with a notch on the antenna socket. This notch must be
alignedwiththemarkingontheprocesstting(themarkingspecies
the position of the polarisation of the radar signal).
