A warning or alarm 
is present.

Depending on the configuration

See error codes table 
(page 66)

1.

See error codes table 
(page 66)

"measured value" 
(000) is incorrect

"measured distance" 
(008) OK?

yes 

→

1.

Check "empty calibration"

 

(005) 

and "full calibration"

 

(006).

2.

Check linearisation:

→

   "level/ullage" (040)

→

   "max. scale" (046)

→

   "diameter vessel" (047)

→

  Check table

no

 

↓

Measurement in 
bypass or stilling 
well?

yes 

→

1.

In "tank shape" (002) is bypass 
or stiliing well selected?

no

 

↓

An interference echo 
might be under 
evaluation.

yes 

→

1.

Carry out interference echo 
suppression

→

  "basic setup" (00)

No change in 
measured value on 
filling/emptying

Interference echoes 
from fixings, nozzles 
or build-up on sensor 
membrane

1.

Carry out interference echo 
suppression

→

  "basic setup" (00)

2.

Clean sensor if necessary

3.

If necessary, select better 
installation position

4.

If necessary due to wide 
interference echoes, set 
function "detection window" 
(0A7) to "off".

With an uneven 
surface (e. g. 
filling, emptying, 
running agitator) 
the measured 
value may jump 
sporadically to 
higher levels

Signal is weakened 
by uneven surface — 
periodically 
interference echos, 
e. g. from internals, 
are stronger

1.

Carry out interference
echo suppression

→

  "basic setup" (00)

2.

Set the "process cond."

 

(004) to 

"calm surface" or 
"add. agitator"

3.

Increase "output damping"

 

(058)

4.

If necessary, select a different 
installation position and/or a 
larger sensor
