Honeywell Description of Parameters 143
323 AI1 signal inversion 3457 (2.2.7, 2.2.19, 2.2.2.6)
If this parameter = 0, no inversion
of analogue U in
signal takes place.
Note: In application 3, AI1 is place B
frequency reference if parameter ID131= 0
(default).

324 AI1 signal filter time 34567 (2.2.8, 2.2.20, 2.2.2.2)
When this parameter is given a value
greater than 0 the function that filters out
disturbances from the incoming analogue
signal is activated.
Long filtering time makes the regulation
response slower. See Figure 8-20.
