Service
WARNING!
Only authorized persons may open the analyzer cover or
perform internal maintenance . Contact ABB for
maintenance instructions and maintenance kits . Make sure
the analyzer is unplugged before working with the internal
components . Failure to do so may result in damage to the
analyzer and exposure to hazardous radiation .
Cleaning the Analyzer
There is no preventive maintenance to perform on the analyzer
apart from the occasional clean-up of the casing .
Cleaning the Instrument Exterior Casing
To clean the exterior casing, wipe it with a damp cloth .
Preventive Maintenance
The analyzer laser(s) are not field serviceable . Should a laser
fail in the field, the analyzer must be shipped back to ABB for
service repair .
The analyzer is equipped with a magnetic interlock switch .
Whenever the case cover is opened, the magnetic switch breaks
contact from the magnetically encoded counterpart, and power
is interrupted from the Laser Controller PCB in the analyzer,
thus, disabling the laser .
Service to the analyzer must be performed only by certified
service personnel trained on servicing this instrument .
User adjustments inside the analyzer are not necessary or
recommended by the manufacturer .
Daily Operation Checklist
Table 14 describes routine maintenance tasks that keep your
analyzer operating smoothly .
Table 14: Maintenance Checklist
Frequency
Task
On the Spectrum display, verify that the spectrum is
correct. The spectrum should appear as shown in Figure 23.
•
Become familiar with the normal appearance of the
spectrum (the best way of diagnosing analyzer
performance) . Any deviations from normal could
indicate a problem with the analyzer .
Every 1-2 days
•
Log the transmitted intensity displayed in the upper
panel of the Spectrum screen . Any decrease in
transmitted intensity could be indicative of dirty
mirrors .
•
Log the analyzer pressure . Any decrease in pressure
could be indicative of an obstruction in the flow
system . An increase in pressure could be indicative of
a leak in the system or a pump failure .
Every 3-6 days Check the laser offset and adjust if necessary. (Figure 36)
Recommended Maintenance
The recommended maintenance steps, when health metrics
suggest maintenance is needed, are:
• OA-ICOS mirror cleaning
• Inline particulate filter replacement
• Solid-state drive (SSD) disk space
