10 Diagnostics and servicing

VEGAPULS C 11 • Two-wire 4 … 20 mA

58340-EN-200806

Fault description

Cause

Rectification

Measured value fluctuates

around 10 … 20 %

Level

time

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

Reflections from the medium surface

via the vessel wall (deflection)

Select a more suitable installation po-

sition, optimize sensor orientation, e.g.

with a swivelling holder

Measured value jumps spo-

radically to 100 % during

filling

Level

time

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

Rectification

Measured value remains un-

changed in the close range

during emptying

Level

time

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

Level

time

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

Measured value fluctuates

around 10 … 20 %

Level

time

Various echoes from an uneven medi-

um surface, e.g. an extraction funnel

Check parameter "Material Type" and

adapt, if necessary

Reflections from the medium surface

via the vessel wall (deflection)

Optimize installation position and sen-

sor orientation

10.6 Software update

The device software is updated via Bluetooth.
The following components are required:

•

Instrument

•

Voltage supply

•

PC/notebook with PACTware/DTM and Bluetooth USB adapter
