Description
The combustibles calibra-
tion slope.
The combustibles slope
warning threshold.
The amount of time that
the combustibles process
variable will take to reach
90% of the actual process
variable.
The highest combustibles
temperature since power
on.
Combustible block T/C
voltage (Valid only with
Type 3 sensor).
The time until the next au-
tomatic calibration of the
combustibles sensor.
Combustible calibration
gas tolerance check.
The duration of the com-
bustibles sensor zero cycle.
Indicates whether combus-
tibles sensor zero is ena-
bled.
The time between combus-
tibles sensor zero cycles.
Indicates whether the com-
bustibles analog output
should track the input dur-
ing combustibles sensor
zero or lock at the last proc-
ess reading. (0 = None, 1 =
O , 2 = CO , 3 = Both)
2 2
The duration of the com-
bustibles sensor zero
purge.
The current step of the
combustibles sensor zero
cycle (0 = Idle, 1 = Flowing,
2 = Purging)
