Alarm
Type Condition / Description / Suggested Corrective Action
8 4 Warning w Check XSCode [Advice: Review-Extended-Status-Code]
XSCode alarm conditions may be present.
Corrective Action:
• Review and interpret current XSCode (Stat\History menu) for additional alarms. At-
tempt to correct any alarm conditions.
16 5 Warning w Dirty Cell [Possible-Cell-Contamination]
The Measuring Cell is contaminated with excessive condensates or other particulate.
Corrective Action:
• Review the ^HCMir and ^WMir history buers (Stat\History menu) to see if either of
these parameters has changed recently or if one has a brightness level of over 400 at
the end of the Purging/Hold Stage. Review the End-of-Run type parameter
(ApplicCFG : RunType) and make sure it is set to HCDP.
• From the RUN menu check the HCDP temperature to see if it is particularly high. If so,
view the ApplicCFG menu and increase the MTHi setting and the Purge time, and
recheck the HCDP temperature.
• Ensure that the enclosure/shelter housing the analyzer is adequately heated. The
surrounding ambient temperature should be at least 15 °C (27 °F) above the highest
expected HCDP temperature.
• If necessary clean the Measuring Cell and Filterblock Assemblies and replace all o-rings
and Membrane Filters. Also, inspect the sample lines and clean or replace them.
32 6 Fault f H2O Optics [Problem-In-Water-Side-Optical-Path]
There is a problem with the water-side optics within the Measuring Cell. An example
of this condition is if, at the beginning of the Purging/Hold Stage, the water-side
phototransistor signal is signicantly higher or lower than normal.
Corrective Action:
• Review and interpret the current XSCode (Stat\History menu) to determine the cur-
rent alarm conditions. Attempt to correct any alarms.
If necessary, contact AMETEK Service for assistance.
64 7 Fault f HC Optics [Problem-In-Hydrocarbon-Side-Optical-Path]
There is a problem with the hydrocarbon-side optics within the Measuring Cell.
An example of this condition is if, at the beginning of the Purging/Hold Stage, the
hydrocarbon-side phototransistor signal is signicantly higher or lower than normal.
Corrective Action:
• Review and interpret the current XSCode (Stat\History menu) to determine the cur-
rent alarm conditions. Attempt to correct any alarm conditions.
If necessary, contact AMETEK Service for assistance.
