With Forward flow option
• a (—): The flow components outside the scaled measuring range cannot be taken into
account for signal output.
The diagnostic message S441 Curr.output 1 to n is displayed.
• b (- -): The current output signal is proportional to the process variable assigned.

With Forward/Reverse option
This option is not possible in this case as the values for the 0/4 mA value parameter
(→  112) and 20 mA value parameter (→  114) have different signs.
With Rev. flow comp. option
Flow components outside the span are buffered, balanced and output after a maximum
delay of 60 s.
