IN ALG 1
(continued)
INPUT ALGORITHM 1 (continued)
FFWD MULT
FEEDFORWARD MULTIPLIER - applies to Loop 1
only and uses Input A, following a Ratio and Bias
calculation as a value multiplied by the PID
computed output value and sent, as an output value,
to the final control element. This algorithm will only
function in automatic mode.
Controller Output = PID Output x (Input A x Ratio + Bias )
AA
CONSTNT K
0.001 to 1000
WEIGHTED AVERAGE RATIO OR K CONSTANT
FOR MATH SELECTIONS - Only applicable for
algorithms "WTD AVG" or Math selections
"MUL DIV ", MULTIPLY ", "MULT DIV", or
"MULTIPLY"
CALC HIGH
–999 to 9999
CALCULATED VARIABLE HIGH SCALING
FACTOR FOR INPUT ALGORITHM 1 - Does not
apply to Feedforward Algorithms.
CALC LOW
–999 to 9999
CALCULATED VARIABLE LOW SCALING
FACTOR FOR INPUT ALGORITHM 1 - Does not
apply to Feedforward Algorithms.
