Table 9: Fault Criteria for Analyzer Alarms
Fault Condition
The laser fitting condition is poor. Occurs when
Fit is not optimal fit is no longer working, peaks have been lost, or
spectrum is unknown.
Not within Occurs when pressure is outside of the operating
operating range range.
Limited hard drive Occurs when the internal hard drive has < 10% of
space space left. Delete unnecessary data files.
Mirrors have Occurs when the ringdown time has degraded by
declined in > 20% of the factory value. Mirror cleaning is
reflectivity required.
Peak is outside Occurs when linelock control voltage is no longer
control range able to control.
Signal power has Occurs when laser signal power has degraded by
degraded > 20% of the factory value.
Maintenance Occurs when the analyzer requires maintenance
needed now (every 381 days).
CROSS OVER
The laser fitting condition is not optimal. Occurs
Fit is not optimal when residuals of fit go above normal operational
values.
Occurs when the specified operational pressure is
Noisy
not optimal.
Occurs when the internal hard drive has < 20%
