INPUT ALGORITHM 1
INPUT ALGORITHM 2
SOURCE OF PERCENT CARBON MONOXIDE—
Select either a fixed value for %CO value (PCT CO)
or use a live value from Analog Input 3.
MANUAL—Operator enters %CO as a Fixed Value
per the PCT CO configuration.
INPUT 3—Input 3 is used to provide the %CO value
to the Carbon Potential algorithm.
ATTENTION This prompt only appears when one
of the Carbon Potential algorithms is selected and
Input 3 is one of the following types: 0-20 mA, 4-20
mA, 0-5 V or 1-5 V.
PERCENT CARBON MONOXIDE—Used only when
a Carbon Potential algorithm is selected and PCO
SEL is set to MANUAL. Enter a value in percent of
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
ATTENTION This prompt appears only when one
of the Carbon Potential algorithms is selected.
HYDROGEN CONTENT FOR DEWPOINT—Used
only when Dewpoint is selected. Enter a value for
the percentage of Hydrogen content that is
applicable.
ATMOSPHERIC PRESSURE COMPENSATION—
Used only when Relative Humidity is selected. Enter
the value of the atmospheric pressure of the
process.
