3.4.1 Pump In Flow.
This fault might indicate one of the following errors. There is an
occlusion in the sample inlet or outlet. A probable course for this
could be occluded (or blocked) tubing, external filter, inlet filter or a
defective pump.
Corrective actions eliminate occlusion.
3.4.2 New NO Sensor
This fault indicate that the Full-scale output of the NO sensor is
≤80% of full scale value when sensor was installed. The NO sensor
must be replaced with a new NO sensor.
Please refer to section 4.3.8 and 5.1.8 when installing a new NO
sensor
3.4.3 New O
2
Sensor
The O
2
sensor output is detected to be below a specified limit during
Zero/O
2
Span Calibration. Replace the O
2
sensor. Please refer to
section 5.1.8 when installing a new O
2
sensor.
3.4.4 IR signal lost
This fault indicate that the sample Cell is contaminated. The sample
cell and windows must be cleaned. Might also display CO
2
and Freon
data invalid in the Data Status section of the status window see
figure 3.10.
3.4.5 Pump Out Flow
Sample gas path is occluded at outlet during Zero/O
2
span
calibration.
Corrective action: Clear outlet occlusion. Use the pump on command
see section 5.1.3 and perform a new Zero/O
2
span calibration see
section 4.2.1.
Might also display a Zero calibration fail error in the Data status of
the status screen.
CO
2
, Freon, NO Zero calibration fail and O
2
span calibration fail will be
displayed.
