P3.12.3.1 Feedback function 1 9 1 333
1 = Only Source1 in use
2 =
SQRT(Source1);(Flow=Con-
stant x SQRT(Pressure))
3 = SQRT(Source1- Source 2)
4 = SQRT(Source 1) + SQRT
(Source 2)
5 = Source 1 + Source 2
6 = Source 1 - Source 2
7 = MIN (Source 1, Source 2)
8 = MAX (Source 1, Source 2)
9 = MEAN (Source 1, Source

AI’s and ProcessDataIn are
handled as % (0.00-100.00%)
and scaled according to Feed-
back min and max.
NOTE: ProcessDataIn use
two decimals.
