Setpoint Rate/Ramp/Soak Program Operation
Input Algorithm Selections
Algorithm selections are made in Section 3 – Configuration. The following function
prompts can be found in the Algorithm Set Up group:
IN ALG1
IN ALG2These selections include the following algorithms:
Weighted Average
Feedforward Summer
Relative Humidity
Summer
Hi Select
Lo Select
Multiply Divide
Multiply
Multiply Divide
Multiply
Feedforward Multiplier
Carbon Potential (several types)
Dewpoint
Input A, Input B, and Input C selections for these formulas are found in Section 3 –
Configuration; Set Up group ALGORTHM, under the following function prompts:
ALG1 INA
ALG1 INB
ALG1 INC
ALG2 INA
ALG2 INB
ALG2 INC
8-Segment Characterization
This is available as part of the Math Algorithm option. Two 8- selections can made in
Section 3 – Configuration; Set Up group ALGORTHM, under function prompts:
8SEG CH1
Xn VALUE
Yn VALUE
8SEG CH2
Xn VALU2
Yn VALU2
An 8-segment characterizer can be applied to either Input 1, Input 2, Output 1, or
Output 2. When Input 1 or Input 2 is used, the selected input's Ratio and Bias are
applied to the Xn values.
When one of the loop outputs is selected, the Xn Values are the output from the
control algorithm, and the Yn Output is the final control element action.
