Parameter Definition

ALGORITHM 1, INPUT B SELECTION will represent one of the available selections.

Input 1

Input 2

Output – Should not be used for Three Position Step Control applications)

ALGORITHM 1, INPUT C SELECTION will represent one of the available selections.

None

Input 1

Input 2

Output – Should not be used for Three Position Step Control applications)

PERCENT CARBON is only applicable when Carbon Potential is selected. Enter the value in percent carbon monoxide that is applicable for the enriching gas used in fractional form.

FOR EXAMPLE:

Natural Gas = 20.0 % CO, then setting is 0.200

Propane Gas = 23.0 % CO, setting is 0.230

INPUT ALGORITHM 1 BIAS—Does not apply to selections: FFWRD, FFWDMU, HISEL or LOSEL.

HYDROGEN CONTENT FOR DEWPOINT is only applicable when Dewpoint is selected. Enter a value for the percentage of Hydrogen content that is applicable.

Math Algorithm Notes:

1.Calculation ranges for the Math Algorithms are set via CALC HI and CALC LO parameters and are between –999. and 9999. The SP High and Low values (SP Range) are independent of these settings and can be any value between –999. and 9999.

2.The CALC HI and CALC LO values determine the range limits for the SP High and Low values for the Weighted Average, Summer, Hi Select and Low Select algorithms.

3.If the Ratio for Input 2 is set to 0.0, then a constant value may be used for the Input 2 value via the Input 2 Bias setting. For this configuration, the Input 2 low range and the Sooting diagnostic messages are disabled.
