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.
