Adjustment system
The sensor is adjusted via the four keys of the
indicating and adjustment module. The LC display
indicates the individual menu items. The functions
of the individual keys are shown in the above
illustration. Approx. 10 minutes after the last
pressing of a key, an automatic reset to measured
value indication is triggered. Any values not
confirmed with [OK] will not be saved.
5.4 Setup procedure
Parameter adjustment
To carry out this adjustment, the distance is
entered for full and empty vessel. If these values
are not known, an adjustment with distances, for
example, of 10 % and 90 % is also possible.
Starting point for these distance specifications is
the lower edge of the flange (flange versions), for
all other versions the lower edge of the transducer.
The real product level during this adjustment is not
important, because the min./max. adjustment is
always carried out without changing the product
level. These settings can be made ahead of time
without the instrument having to be installed.
In the main menu item "Basic adjustment", the
individual submenu items should be selected one
after the other and provided with the correct
parameter values.
Carrying out min. adjustment
Proceed as follows:
1 Move from the measured value display to the
main menu by pushing [OK].

2 Enter the appropriate distance value in m
(corresponding to the percentage value) for the
full vessel. Keep in mind that the max. level
must lie below the dead band.
3 Save the settings with [OK] and move to
"Medium selection" with [->].
Medium selection
Each product has different reflective properties. In
addition, there are various interfering factors which
have to be taken into account: agitated product
surfaces and foam generation (with liquids); dust
