AI0 - Process Variable
C256 5-4 AI0 Engineering Span - Enter a value, that when added to the
Engineering Zero value, will produce an upper range value in
engineering units that represents the PV transducer upper
range signal value.
100
C276 5-4 AI0 Engineering Zero - Enter a value that represents in
engineering units the PV transducer lower range signal value.
0
B269 5-4 AI0 Digital Filter Index - This is a first order filter that can be
applied to the PV transducer signal. See Table 5-4 for input
values.
3
L416 5-4 AI0 0-5 V Input - Enter a value that matches the signal voltage
range of the PV transducer. 1 = 0 - 5 V range; 0 = 1 - 5 V
range.
0
L440 5-4 AI0 Square Root Signal - It is used if the PV transducer is a
nonlinear differential pressure (DP) cell that provides a
squared signal value. 0 = input is already linear; 1 = square
root to restore linearization.
0
AI1 - Wild Variable
C257 5-4 AI1 Engineering Span - This value is set to 100 by CS3;
however, it can be changed. Enter a value, that when
added to the Engineering Zero value, will produce an upper
range value in engineering units that represents the Wild
Variable transducer upper range signal value.
0
C277 5-4 AI1 Engineering Zero - Enter a value that represents in
engineering units the Wild Variable transducer lower range
signal value.
0
B270 5-4 AI1 Digital Filter Index - This is a first order filter that can be
applied to the Wild Variable signal. See Table 5-4 for input
values.
3
L417 5-4 AI1 0-5 V Input - Enter a value that matches the signal voltage
range of the Wild Variable transducer. 1 = 0 - 5 V input
range; 0 = 1 - 5 V input range.
0
L441 5-4 AI1 Square Root Signal - It is used if the Wild Variable
transducer input is a squared signal value that must be
linearized. 0 = input is already linear; 1 = square root to
restore linearization.
0
AI2 - Additive Feed Forward
C258 5-4 AI2 Engineering Span - Enter a value, that when added to
Engineering Zero, will produce an upper range value in
engineering units that represents the Additive Feed Forward
upper range signal value.
0
C278 5-4 AI2 Engineering Zero - Enter a value that represents in
engineering units the Additive Feed Forward lower range
signal value.
