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 (% H2)
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.
