AI5 - Process Variable Loop 4 (Cont)
L421 5-4 AI5 0-5 V Input - Enter a value that matches the signal voltage
range of the Loop 4 PV transducer. 1 = 0 - 5 V range; 0 = 1 -
5 V range.
0
L445 5-4 AI5 Square Root Signal - It is used if the Loop 4 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
AI6 - Remote Setpoint Loop 3 (Is affected by Setpoint Related Datapoints)
L163 5-9 CON2 Remote Setpoint Enable - This datapoint is controlled by
CCI2. When CCI2 is a closed contact, this datapoint is set to
1 to allow the modified Loop 3 Remote Setpoint to become
the value used as the control setpoint if the R/L push button
is in Remote.
0
C184 5-9 CON1 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
C185 5-9 CON1 Remote Setpoint Ratio (K1) - See Remote Setpoint bias (B1)
above.
1
C262 5-4 AI6 Engineering Span - Set to 100 by CS41; however, it can be
changed. Enter a value, that when added to Engineering
Zero, will produce an upper range value in engineering units
that represents the Loop 3 Remote Setpoint upper range
signal value.
100
(CS41)
C282 5-4 AI6 Engineering Zero - Enter a value that represents in
engineering units the Loop 3 Remote Setpoint lower range
signal value.
0
B275 5-4 AI6 Digital Filter Index - This is a first order filter that can be
applied to the Loop 3 Remote Setpoint signal. See Table 5-4
for input values.
3
L422 5-4 AI6 0-5 V Input - Enter a value that matches the signal voltage
range of the Loop 3 Remote Setpoint signal. 1 = 0 - 5 V
input range; 0 = 1 - 5 V input range.
0
L446 5-4 AI6 Square Root Signal - It is used if the Loop 3 Remote Setpoint
input is a squared signal value that must be linearized. 0 =
input is already linear; 1 = square root to restore linearization.
