De-
fault
AI0 - Process Variable Primary
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 Primary transducer
upper range signal value.
100
C276 5-4 AI0 Engineering Zero - Enter a value that represents in engi-
neering units the PV Primary 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 Primary 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 Primary 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 Primary 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 - Remote Setpoint Primary (Is affected by Setpoint Related Datapoints)
L115 5-9 CON0 Remote Setpoint Enable - This datapoint is controlled by DI1.
When DI1 is a closed contact, this datapoint is set to 1 to
allow the modified Primary Remote Setpoint to become the
value used as the control setpoint if the R/L push button is in
Remote.
0
C112 5-9 CON0 Remote Setpoint Bias (B1) - This datapoint and Remote
Setpoint Ratio (K1) allow the Remote Setpoint input to be
modified by the Setpoint Generator.
Setpoint = [Remote Setpoint X Ratio] + Bias
SP = [RSP X K1] + B1
The B1 and K1 datapoints are modified when the input signal
must be scaled to match the setpoint range desired.
0
C113 5-9 CON0 Remote Setpoint Ratio (K1) - See Remote Setpoint bias (B1)
above.
1
C257 5-4 AI1 Engineering Span - Enter a value, that when added to
Engineering Zero, will produce an upper range value in
engineering units that represents the Primary Remote
Setpoint upper range signal value.
0
C277 5-4 AI1 Engineering Zero - Enter a value that represents in
engineering units the Primary Remote Setpoint lower range
signal value.
0
B270 5-4 AI1 Digital Filter Index - This is a first order filter that can be
applied to the Primary Remote Setpoint 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 Primary Remote Setpoint. 1 = 0 - 5 V range; 0 =
1 - 5 V range.
