11.4 Error indications
Possible cause Recommended measures
[E�000] Fault in the electronics� Replace the unit�
[E�031]
Probe detached from the unit;
possibly incorrect setting of the
probe length�
Check whether the probe is still
attached to the unit�
Check the parameter [LEnG]�
[E�033]
Measurement disturbed by
heavy foam formation or
turbulence�
• Install the unit in a still pipe or bypass�
• Set or increment [dFo] (→ 10.5.8)
Measurement disturbed by
separation layers (e�g� oil layer
on water)�
Remove the oil layer by suction, stir the
medium, verify the composition�
Rod or process connection
soiled�
Clean the rod and the process
connection, carry out a reset�**
Installation conditions were not
adhered to�
Observe the notes in "Installation"
(→ 6).
Probe length, type of probe
or sensitivity (setting to the
medium) is incorrect�
Correct the settings (→ 10.2), then
carry out a reset�**
[E�034] Atypical, abrupt level changes�*
Check the dynamics (if necessary, use
a still pipe or bypass), then carry out
a reset�**
[SC1]
Flashing: short circuit in
switching output�
Remove the short circuit�
[PArA] Faulty data set Reset to factory settings (→ 10.6).
* The unit carries out plausibility checks to increase the operational reliability� Atypical level
changes can be caused e�g� by heavy soiling or strong turbulence� With the parameter
[dFo] the response of the unit can be delayed (→ 10.5.8).
** Carry out a reset (power off and on again) after rectifying the fault to reset the error
