What are Error Messages

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 remote
cable (see documentation for the APG interface).
