What Are 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, or 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 module
logbook.
If an error occurs outside a method run, other modules will not be informed about
this error. If it occurs within a method run, all connected modules will get a
notification, all LEDs get red and the run will be stopped. Depending on the
module type, this stop is implemented differently. For example, for a pump the
flow will be stopped for safety reasons. For a detector, the lamp will stay on in
order to avoid equilibration time. Depending on the error type, the next run can
only be started, if the error has been resolved, for example liquid from a leak has
been dried. Errors for presumably single time events can be recovered by
switching on the system in the user interface.
Special handling is done in case of a leak. As a leak is a potential safety issue and
may have occurred at a different module from where it has been observed, a leak
always causes a shutdown of all modules, even outside a method run.
In all cases, error propagation is done via the CAN bus or via an APG/ERI remote
cable (see documentation for the APG/ERI interface).
