The HS maintains internal event logs. Use these logs to
troubleshoot problems, especially when a message no longer
appears on the display. The most useful logs for
troubleshooting are the Sequence log and the Event log.
The Sequence log contains an entry for up to 256 significant
events that occurred during the sequence. These entries
include vial start and stop times, as well as deviations from
the method. The HS also logs parameter changes, method
changes, and sequence changes (if these occur during
sequence execution). If the log becomes full, the HS
overwrites the oldest entries. The log clears every time the
HS starts a new sequence.
The Event log contains up to 250 entries for general events
(events not related to a sequence) that occur to the HS. For
example, this log records power on/off events, faults, and
firmware updates. If the log becomes full, the HS overwrites
the oldest entries.
The Maintenance log contains up to 128 entries that record
whenever a maintenance counter crosses a limit or when the
counter is reset. If the log becomes full, the HS overwrites
the oldest entries.
To access the logs, press [Logs] until the desired log displays.
The display will indicate the number of entries the log
contains. Scroll through the list.
