Maintenance of the XDS Process Instrument
The XDS Process Analytics Instrument is designed to be trouble-free, with a minimum of
maintenance. These guidelines should always be followed:
1. Keep the outer enclosure as clean as possible, to maintain heat transfer characteristics.
2. Do not allow dirt buildup in the heat sink fins. These should be blown clear of any dirt or
obstructions on a regular basis.
3. Be extremely careful of the fiber optic bundles. They are easily damaged by impact, bending
too tightly, and by physical abuse. This will affect measurement sensitivity and may be
catastrophic. Fiber optic replacement is expensive.
4. Consider lamp replacement on a regular schedule that coincides with normal factory
downtime. Lamp life is expected to be in excess of 4000 hours. However, when running 24
hours per day, it is advisable to change lamps pro-actively to avoid unscheduled shutdowns.
5. Always keep one or two spare lamps on hand for unexpected emergencies.
