VEGAPULS C 11 • Two-wire 4 … 20 mA
58340-EN-200806
Fault description Cause Rectication
Measuredvalueuctuates
around 10 … 20 %
Level
time
0
Various echoes from an uneven medi-
um surface, e.g. a material cone
Check parameter "Material Type" and
adapt, if necessary
Optimize installation position and sen-
sor orientation
Reectionsfromthemediumsurface
viathevesselwall(deection)
Select a more suitable installation po-
sition, optimize sensor orientation, e.g.
with a swivelling holder
Measured value jumps spo-
radically to 100 % during
lling
Level

0
Changing condensation or contamina-
tion on the antenna
Carry out a false signal suppression
or increase false signal suppression
with condensation/contamination in the
close range by editing
Bulk solids: Measurement error during emptying
Fault description Cause Rectication
Measured value remains un-
changed in the close range
during emptying
Level
time
0
False signal greater than level echo or
level echo too small
Eliminate false signals in the close
range. Check: Antenna must protrude
out of the nozzle
Remove contamination on the antenna
Minimize interfering installations in the
close range by changing the polariza-
tion direction
After eliminating the false signals, the
false signal suppression must be de-
leted. Carry out a new false signal
suppression
Measured value jumps spo-
radically towards 100 %
during emptying

Changing condensation or contamina-
tion on the antenna
Carry out false signal suppression or in-
crease false signal suppression in the
close range by editing
