Critical Failure Messages

100 Accela PDA Detector Hardware Manual
Cause
An error has occurred during a run.
Both lamps are off.
This section describes the various log entries that are possible when operating the Accela PDA
Detector from your Thermo Scientific data system.
Note For further information, document the log entry and contact Thermo Fisher
Scientific technical support.
The diagnostics Event Log chronologically records messages relating to detector or system
problems. The messages fall into three categories:
• Critical Failure Messages
• Warning Messages
• Information Messages
Critical failure messages indicate that the PDA cannot perform its function properly. If a
chromatographic run is in progress when a critical failure occurs, the data might be corrupted
or lost, and the run terminates. Possible critical failure messages include the following:
• Filter wheel misaligned
• Failed to turn on the Deuterium lamp
• Failed to turn on the Tungsten lamp
Remedy
See software to determine the nature of the error,
or begin the run again.
Turn on the lamps and allow 1½ hours for
warm-up.
