12.1.2 Window mode - Window function setting (Fno / Fnc)
The window function enables monitoring of a particular range. An upper and a lower switch
point which defines the range can be assigned to each switching output.
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):
Abbreviations:
"FH1", "FH2" = upper switch value 1 / upper switch value 2
"FL1", "FL2"
= lower switch value 1 / lower switch value 2
"FNO"
= N/O when window function is active
"FNC"
= N/C when window function is active
Notes:
•
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.
