De-
fault
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
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.
0
B271 5-4 AI2 Digital Filter Index - This is a first order filter that can be
applied to the Additive Feed Forward signal. See Table 5-4
for input values.
3
L418 5-4 AI2 0-5 V Input - Enter a value that matches the signal voltage
range of the Additive Feed Forward signal. 1 = 0 - 5 V input
range; 0 = 1 - 5 V input range.
0
L442 5-4 AI2 Square Root Signal - It is used if the Additive Feed Forward
input is a squared signal value that must be linearized. 0 =
input is already linear; 1 = square root to restore linearization.
0
AI3 - Control Element Feedback
C259 5-4 AI3 Engineering Span - Set to 100 by CS2. 0
AO0 - Backup Control Output
L472 5-5 AO0 0-20 mA Output - 0 = 4-20 mA signal; 1 = 0-20 mA signal.
Enter a value to match the output valve requirements.
0
L120 5-9 CON0 Manual Fallback Disable - 0 = always power up in manual;
1 = auto/manual selector unchanged at power up.
0
L122 5-9 CON0 Hard Manual Limit - 1 = apply output limits to the final output
of the Auto-Manual Generator. It affects both the manual
push buttons and the controller’s result. 0 = do not apply
limits.
