Error messages
If empty or full adjustment cannot be made, the red LED flashes quick-
ly at about 8Hz after the adjustment attempt (adjustment error).
To delete this error message press the programming pushbutton once
or power off and then power on again. The measured values succes-
sfully read so far remain unchanged.
Possible reasons for an error message:
• The signal difference between the empty and full state is too small
(e.g. empty and full adjustment without sufficient change of the
level).
• The signal change between the empty and full state is in the wrong
order (e.g. empty adjustment in the full state and then full adjust-
ment in the empty state).
• Empty adjustment outside the operating range (e.g. empty adjust-
ment in case of direct contact with an electrically grounded medi-
um, e.g. if the active zone is immersed in water).
Help: Avoid the above-mentioned errors and repeat the adjustment for
error correction.
Further faults:
• Electronic fault or sensing zone of the unit damaged.
• Internal fault (can only be deleted by power off and then power on
again, hardware reset).
