HYDAC ELECTRONIC AquaSensor AS 3000 Operation Manual page 61

AS 3000 IO-Link
The particular output is switched when the level or temperature enters this range. When the
level leaves this range, i.e. when the switch-back point has been exceeded or fallen below,
the output switches back.
The lower switch-back value is just below the lower switch value. The upper switch-back
value is just above the upper switch value. The range between the switch value and the
switch-back value forms a safety margin which prevents unwanted switching operations
from being triggered.
Example for switching output 1 (N/C and N/O function):

FH1 plus 0.4%FS

NOTICE:
•
Setting the upper switch value (FH) is only possible if it lies above the lower
switch value (FL).
•
The window function only works properly (switching on and off) if all switch
values (including the safety margin) are greater than 0 cm + offset value and
below the upper measuring range limit + offset value.
