INPUT ALGORITHM 1
INPUT ALGORITHM 2
PCO SEL 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
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.
PCT CO
0.020 to 0.350 (fractional
percent of CO)
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.
PCT H2
1.0 to 99.0 (% H
2
)
HYDROGEN CONTENT FOR DEWPOINT—Used
only when Dewpoint is selected. Enter a value for
the percentage of Hydrogen content that is
applicable.
ATM PRES
590.0 to 760.0 (mm Hg)
ATMOSPHERIC PRESSURE COMPENSATION—
Used only when Relative Humidity is selected. Enter
the value of the atmospheric pressure of the
process.
