Failed lamp indications
When code 128 is produced, the analyzer lamp has failed and must be replaced. Code 128
indicates that the UV lamp has failed and no longer supports proper analyzer operation. If the
UV lamp fails, the analyzer switches operation to the secondary UV lamp.
Under a code 128 condition, the lamp is no longer producing adequate levels of UV light to
support proper sample oxidation.
Lamp replacement procedure
Replacement UV lamp part number: FG7001014.
To replace a lamp, follow these steps:
1) At the home screen, touch the << icon to open the sliding toolbar.
2) Touch the diagnostics icon or touch the dual UV lamp status indicator in the lower
right corner of the screen.
3) Touch the replace lamp icon.
4) Select the lamp to be replaced.
5) Touch “Run Wizard” to run the lamp replacement wizard or “Replace Now” to skip
the replacement wizard.
• The wizard provides step-by-step instructions for replacing the lamp. Read the
instructions completely. You will be instructed to power down the analyzer and
proceed with lamp replacement.
• If you touch “Replace Now”, the display skips the replacement wizard and warns of
potential voltage and mercury dangers. Touching the forward icon takes you to a
caution that describes how to handle the UV lamp. Touching the forward icon again
takes you to a dialog box that asks you to power down the analyzer. See
