After mounting you must adjust the unit to the empty tank.
1
until the material is min. 20 mm away from the active zone.
2
max. 5 s
• During the empty adjustment the unit determines a measured value
for the empty state,
• automatically generates a hypothetical value for the full state (from
the measured value for the empty state and a factory predefined
signal difference).
• It then sets the optimum switching threshold between the two values.
The unit is then ready for operation.
For an optimum adjustment of the unit to your application it is recom-
mended to carry out a full adjustment in addition to an empty adjust-
ment as well.
1
until the medium covers the active zone.
2
5 ... 10 s
• During the full adjustment the unit adopts the measured value for
the empty state determined during the empty adjustment,
• determines a measured value for the full state and
• sets the optimum switching threshold between the two values.
This ensures an optimum adjustment of the unit to your appli-
cation.
You can repeat the full adjustment as often as you wish. The stored
value for the empty state is not overwritten by the full adjustment.
When an empty adjustment is made again the previously defined
values are overwritten/replaced by the newly determined values.
So always carry out the empty adjustment first, then the full adjust-
ment.
Empty the tank
Press the programming button until the
green LED flashes
(= the unit is in the adjustment mode).
After adjustment the green LED is lit
continuously (the unit is in the operating mode).
Fill the tank
Press the programming button until the
green LED flashes quickly
(= the unit is in the adjustment mode).
The LED first flashes slowly (about 1 Hz), after
5 s it flashes double as quickly (about 2 Hz).
After adjustment the green and yellow LED's are
lit continuously (the unit is in the operating
mode).
