12 Troubleshooting
1 Concepts and General Tasks
To View the Run Log, Maintenance Log, and Event Log
The GC maintains internal event logs, each of which holds
up to 250 entries. Use these logs to troubleshoot problems,
especially when a message no longer appears on the display.
To access the logs, press [Logs] to toggle to the desired log.
The display will indicate the number of entries the log
contains. Scroll through the list.
Run Log For each run, the run log records deviations from
the planned method. This log is overwritten at the start of
each run. The run log information can be used for Good
Laboratory Practice (GLP) standards and can be uploaded to
an Agilent data system. When the Run Log contains entries,
the Run Log LED lights.
Maintenance Log The maintenance log contains an entry for
each time an Early Maintenance Feedback limit is reached,
reset, or changed. The log records details such as the
counter item, the counter value, the new counter value, and
whether or not the counter was reset (indicating a part
replacement). When the maintenance log is full, the GC
overwrites entries, beginning with the oldest.
Event Log The event log records events such as shutdowns,
warnings, faults, and GC state changes (start run, stop run,
and so forth) that occur during GC operation. When the
event log is full, the GC overwrites entries, beginning with
the oldest.
