Figure 50: Indicators Page
The specific faults shown on the Indicators page are listed in Table 20.
Table 20: Analyzer Faults
Fault Explanation
Measure Out of Range
Spectrometer signal is out of range while analyzer is
measuring sample (signal either off scale or too low)
Reference Out of Range
Spectrometer signal is out of range while analyzer is in back
purge mode (signal either off scale or too low)
Dark Out of Range
Spectrometer dark level (i.e. signal when no light is present) is
either too low or too high
Low Cell Temperature
Measurement cell temperature is below low cell temperature
fault setpoint
High Cell Temperature
Measurement cell temperature is above high cell temperature
fault setpoint
Low Probe Temperature Temperature of gas exiting the probe is below the low probe
temperature setpoint
High Probe Temperature Temperature of gas exiting the probe is above the high probe
temperature setpoint
IO Board
Control computer is unable to communicate with the IO board
or spectrometer
Some of these faults may clear by themselves but others may require maintenance or even
hardware replacement to resolve. Refer to Section 7.2 for more detail on how to troubleshoot
active faults.
Table 21 describes each of the warnings listed int the warning table on the Indicators page.
