5.1.2 Configuring switching functions
Prerequisite: The parameter group SP-P is selected
1 Press the PARA button to select the required
parameter
• The name and the value of the parameter are
displayed
2 Use the CH button to assign the switching function
to a channel
• The switching functions can be assigned to the
channels any way
• The two threshold values of the switching func-
tion are always assigned to the same channel
3 Use the arrow buttons to modify the threshold
value
• The value of the parameter is changed
4 Repeat the steps 1 to 3 to change further parame-
ters of the same parameter group
5.1.3 Adjustment range
Adjustment range of the lower threshold value
The lower threshold value of a switching function can be
set in the following pressure range:

Adjustment range of the upper threshold value
The upper threshold value of a switching function can be
set in the following pressure ranges:
Tab. 5-2 Adjustment range of the upper threshold values
This means that the hysteresis amounts to 10 % of the
lower threshold value (logarithmic sensors) or to 1 % of
the full-scale range (linear sensors) at least. If another
sensor type is connected to a channel, the respective
threshold values will be adjusted automatically if neces-
sary.
