Error Messages
Error messages are displayed in the user interface when an electronic, 
mechanical, or hydraulic (flow path) failure occurs which requires attention 
before the analysis can be continued (for example, repair, exchange of 
consumables is necessary). In the event of such a failure, the red status 
indicator at the front of the module is switched on, and an entry is written 
into the instrument log book.
This section describes the meaning of autosampler error messages, and 
provides information on probable causes and suggested actions how to recover 
from error conditions.
