Operator Manual Anatel
The following alarm messages also may indicate a deteriorated UV Lamp, requiring that it be
replaced:
• Code 31: See Guide
• Code 32: See Guide
• Code 53: UV Lamp Bad
These messages continue until the UV Lamp is replaced and the Anatel A643a’s internal
counter is reset.
13.4.1 UV Detect Technology
An A643a analyzer equipped with UV Detect will automatically monitor the output of the UV
lamp and alert when the UV output is indicative of a failing lamp or if the lamp has failed
completely and can no longer support proper oxidation. Code 52 indicates a failing lamp.
Code 53 indicates a failed lamp.
Failing Lamp Indications in TOC Analysis Mode:
When Code 52 is indicated by UV Detect, the analyzer UV lamp should be replaced as soon as
possible. UV Detect will generate a Code 52 when the UV output from the lamp has reached a
level that indicate a failing lamp. At this level of UV output the analyzer will continue to oxidize
adequately, but lamp life is extremely limited.
When a failing lamp is detected the analyzer will display Code 52 UV Lamp on the C80
controller alarm status screen and the associated LED for the analyzer will blink Red. If a
printer is connected to the analyzer Code 52 UV Failing will be printed following each TOC
analysis, and the following message will be printed every eight hours - Urgent: U.V. lamp needs
replacement consult your manual or call the Anatel Service Dept. @ 800-866-7889.
Under Code 52 the analyzer will continue to perform TOC analysis, but the lamp life is limited
and should be replaced as soon as possible.
Bad Lamp Indications in TOC Analysis Mode:
When Code 53 is indicated by UV Detect the analyzer lamp has failed and must be replaced.
Code 53 is an indication that the UV lamp has failed and no longer supports proper analyzer
operation.
Under a Code 53 condition the lamp is no longer outputting adequate levels of UV light to
support proper sample oxidation. TOC analysis is no longer supported and the C80 display will
display 53-UV Lamp Bad.
When a bad lamp is detected the analyzer will display Code 53 UV Lamp on the C80 controller
alarm status screen and the associated LED for the analyzer will blink Red. If a printer is
connected to the analyzer Code 53 UV Lamp Bad will be printed following each attempt at a
TOC analysis, along with the following message - Urgent: U.V. lamp needs immediate
replacement, consult your manual or call the Anatel Service Dept. @ 800-866-7889.
