alarm conc nox min
alarm conc pre min
alarm conc no max
alarm conc no2 max
alarm conc nox max
alarm conc pre max
These commands report the NO, NO
2
, NO
x,
and prereactor concentration
alarm minimum and maximum values current setting. The example below
reports that the NO concentration minimum is 62.7 ppb.
Send:
alarm conc no min
Receive:
alarm conc no min 62.7 ppb

, NO
x,
and prereactor concentration
alarm minimum and maximum values to
value
, where
value
is a floating-
point representation of the concentration alarm limits. Values must be in
the units that are currently set for use. The example below sets the NO
concentration alarm maximum value to 115.
Send:
set alarm conc no max 115
Receive:
set alarm conc no max 115 ok
alarm converter temp min
alarm converter temp max
These commands report the converter temperature alarm minimum and
maximum value current settings. The example below reports that the
converter temperature alarm minimum value is 300.0 °C.
Send:
alarm chamber temp min
Receive:
alarm chamber temp min 300.0 deg C
set alarm converter temp min
value
set alarm converter temp max
value
These commands set the converter temperature alarm minimum and
maximum values to
value
, where
value
is a floating-point number
representing converter temperature alarm limits in degrees C. The example
below sets the converter temperature alarm maximum value to 340.0 °C.
