Technical information

NOTE
This parameter is only available when using pressure to
temperature feedback conversion.
If the choice Linear [0] is selected in 20-01 Feedback 1
Conversion, then the setting of any choice in
20-02 Feedback 1 Source Unit does not matter as conversion
will be one-to-one.

ProcessCtrlUnit]
Enter the desired minimum
value for the remote
reference when operating
with 1-00 Configuration
Mode set for Closed Loop
[3] operation. Units are set
in 20-12 Reference/Feedback
Unit.
Minimum feedback will be
-200% of either the value
set in 20-13 Minimum
Reference/Feedb. or in
20-14 Maximum Reference/
Feedb., which ever numeric
value is the highest.
NOTE
If operating with 1-00 Configuration Mode set for Open
Loop [0], 3-02 Minimum Reference must be used.
