Instruction Manual Page 47 of 96
3.4.1 Pump in Flow
This fault indicates that there is an occlusion in the sample inlet.
A probable course for this could be occluded tubing’s, external filter
or inlet filter.
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 CO2, CO and
Ethanol data invalid in the Data Status section of the status window
see figure 3.10 .
3.4.5 Pump Out Flow
a. Sample gas path is occluded at outlet during normal mode
operation.
Corrective action: Clear outlet occlusion. Use the pump on command
see section 5.1.3 .
b. Sample gas path is occluded at the 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
, CO, Ethanol, NO Zero calibration fail and O
2
span calibration fail
will be displayed.
