7 Troubleshooting
7.1 Overview
The following features help you to identify and eliminate the source for problems that may
occur during the operation of the detector or system.
• Status screen on the detector display
The display on the front panel provides a quick visual check of the operational status of
the detector.
• Troubleshooting check to isolate the cause of a problem (→ page 92).
• Self-test diagnostics and error codes
If errors are detected during the self-test diagnostics upon power-up, an error code is
shown on the detector display. For information about the self-test error codes, see the
'Self-Test Error Codes' section (→ section 7.2, page 93).
• Error and warning codes
If a fault or error is detected during the operation of the detector, a code appears on the
detector display. Check the 'Warning and Error Codes' section for recommended courses
of action (→ section 7.3, page 95). If you operate the detector from a chromatography
data system, a message will also be documented in the audit trail of the software.
• Operating problems
For information about operating problems that might occur during the operation of an
UltiMate 3000 system, see the 'Operating Problems' section (→ section 7.4, page 99).
