AI2 - #1 Secondary Process Variable (Cont)
B271 5-4 AI2 Digital Filter Index - This is a first order filter that can be
applied to the #1 Secondary Variable transducer 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 #1 Secondary Variable transducer 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 #1 Secondary Variable
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
AI3 - #2 Secondary Process Variable
C259 5-4 AI3 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 #2 Secondary Variable
transducer upper range signal value.
0
C279 5-4 AI3 Engineering Zero - Enter a value that represents in
engineering units the #2 Secondary Variable transducer
lower range signal value.
0
B272 5-4 AI3 Digital Filter Index - This is a first order filter that can be
applied to the #2 Secondary Variable transducer signal. See
Table 5-4 for input values.
3
L419 5-4 AI3 0-5 V Input - Enter a value that matches the signal voltage
range of the #2 Secondary Variable transducer signal. 1 = 0 -
5 V input range; 0 = 1 - 5 V input range.
0
L443 5-4 AI3 Square Root Signal - It is used if the #2 Secondary Variable
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.

OUT (Setpoint from Loop 1 to Loop 3)
L120 5-9 CON0 Manual Fallback Disable - 0 = always power up Loop 1 in
manual; 1 = Loop 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 Loop 1 Auto-Manual Generator. Affects both the
manual push buttons and the controller’s result. 0 = do not
apply limits.
