Parameter Description
Allows you to adjust the %
Carbon as measured by the
controller to agree with the
results of actual shim stock
tests. This adjustment may
be needed to correct for
specific furnace
characteristics such as
atmosphere differences,
probe location, and furnace
leaks.
Activates anti-sooting feature
that limits the working
setpoint of the carbon control
loop to a value that prevents
sooting in the furnace.
Holds controller output to 0%
until limit is exceeded.
Probe temperature units for
display.
Percent Hydrogen
Allows you to adjust %
Carbon measurement to
compensate for variations in
the amount of CO in the
carrier gas.
Function block will use the
actual %Carbon Monoxide
that is defined through an
analog input.
