Table 9 describes fault criteria for the Analyzer Alarms.

‘A’ refers to Laser 1 and ‘B’ refers to Laser 2. Not all analyzers are equipped
with 2 lasers.

Table 9: Fault Criteria for Analyzer Alarms

Status

Sensor Read

Fault Condition

Description

Data Health

(A/B)

Fit is not optimal

The laser fitting condition is poor. Occurs when
fit is no longer working, peaks have been lost, or
spectrum is unknown.

Pressure

Not within

operating range

Occurs when pressure is outside of the operating
range.

HD Space

Limited hard drive

space

Occurs when the internal hard drive has < 10% of
space left. Delete unnecessary data files.

Mirror Health

(A/B)

Mirrors have

declined in

reflectivity

Occurs when the ringdown time has degraded by
> 20% of the factory value. Mirror cleaning is
required.

Linelock

(A/B)

Peak is outside

control range

Occurs when linelock control voltage is no longer
able to control.

Signal Power

(A/B)

Signal power has

degraded

Occurs when laser signal power has degraded by
> 20% of the factory value.

Maintenance

needed now

Occurs when the analyzer requires maintenance
(every 381 days).

CROSS OVER

Data Health

(A/B)

Fit is not optimal

The laser fitting condition is not optimal. Occurs
when residuals of fit go above normal operational
values.

Pressure

Noisy

Occurs when the specified operational pressure is
not optimal.

HD Space

Low space

Occurs when the internal hard drive has < 20%
space left. Delete unnecessary data files.

Mirror Health

(A/B)

Mirrors have

declined in

reflectivity

Occurs when the ringdown time has degraded by
> 10% of the factory value.

Linelock

(A/B)

Peak is drifting

Occurs when linelock control voltage is
approaching control range limit.

Signal Power

(A/B)

Signal power is

degrading

Occurs when laser signal power has degraded by
> 10% of the factory value.

Maintenance

Maintenance
needed soon

Analyzer maintenance will be needed soon (every
360 days).

Dead Band

Performance

No warning/alarm

If the

Alarm Status is Yellow or

Red,

please refer to the

Maintenance

section on page 65. If issue continues, please contact
