4.5.1   Fault Conditions 

 

Table 9 describes each of the fault conditions listed in the fault table on the Indicators

 

panel.  

 

Table 9: Analyzer Faults 

Fault 

Explanation 

Cell Temperature 

Measurement cell temperature is either below Low Cell 

Temperature setpoint or above High Cell Temperature 

setpoint.  

High High Sulfur 

Measured sulfur vapour content exceeds high sulfur vapour 

concentration fault setpoint 

Measure Range 

Spectrometer signal is out of range while analyzer is 

measuring sample (signal either off scale or too low).  

Reference Range 

Spectrometer signal is out of range while analyzer is in back 

purge mode (signal either off scale or too low) 

Dark Range 

Spectrometer dark level (i.e. signal when no light is present) is 

either too low or too high.  

I/O Board 

System computer is unable to communicate with Input / Output 

board and / or spectrometer 

  

Some of these faults may clear by themselves (particularly the cell temperature fault and the 

high high sulfur fault) 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.  

 

4.5.2  Warning Conditions 

 

Table 10 describes each of the warnings listed in the warning table on the Indicators panel.  

 

Table 10: Analyzer Warnings 

Warning 

Explanation 

Cabinet Temperature 

Control cabinet internal temperature is either below low 

cabinet temperature setpoint or above high cabinet 

temperature setpoint.  

High Absorbance 

Measured absorbance as shown on the Absorbance spectrum 

exceeds 2.0 AU when analyzer is in sampling mode. Typically 

indicates that measured concentration of at least one 

component is out of range 

High Integration Period 

Integration period required to obtain an in-range spectrometer 

signal when analyzer is in back purge mode >  500 

milliseconds.  

Low Reference Peak 

Spectrometer signal peak height when analyzer is in back 

purge mode <24000 A/D counts 

High Sulfur Vapour 

Measured sulfur vapour content exceeds high sulfur vapour 

concentration warning setpoint 

 

Some of these warnings may clear by themselves, particularly the cabinet temperature 

warning and the high sulfur vapour warning, but others will not be able to be cleared without 

performing maintenance on the analyzer. Refer to section 7.2 for more detail on how to 

troubleshoot active warnings.
