4.6 Information Logs
The optical autochanger control panel diagnostic tests have two major purposes.
The first is to provide diagnostic information that can lead to early detection of
an autochanger problem. The second is to provide fault isolation tests.
All the logs are maintained within non-volatile RAM, and so are not affected by
cycling autochanger power. These logs are accessible from the control panel by
using the
INFO
option.
Procedure
To display information about the autochanger (e.g., the error log or move success
log) access the
INFO
