5.11 Hazardous Area Systems
The TDLS200 Analyzer requires a continuous nitrogen or I/A gas purge to prevent ambient oxygen ingress to the
optical path, when oxygen is the measured gas. The flow rate can be minimized as long as it prevents any ambient
oxygen ingress to the measurement optical path. Other purge gases may be used as long as they do not contain
any of the measured gas and are clean, dry, etc. If using a purge gas that also contains the measured gas (e.g.
purge with instrument air and measuring process/combustion oxygen) then the Non-Process Parameters software
feature/parameters will have to be implemented.
For hazardous area operation, the same nitrogen purge gas is used to purge the entire analyzer (including
non-optical path sections such as the electronics).
The process interface may also require purging to maintain clear windows, refer to Process Window Purge details
separately.
NOTE: Please also refer to any separate Purge System Original Manufacturers Operating Instructions and
Manuals in conjunction with this User Guide.
The Purge Systems are not manufactured by Yokogawa Laser Analysis Division.
Please also refer to separate detailed manufacturer’s instructions and start-up information for any Zone 1
or Division 1 automatic purge controller unit operational details. Failure to follow the manufacturer’s
guideline can result in damages and/or non-functionality of the purging system!
