Analytical Station Status Probable Cause
Paused until error Analyzer needs to stop after an
resolved. abnormal condition occurred
(for example, clearing flow cell
clogs).
Stopped - inoperable. +48 V power to Analyzer

If this error occurs it will
not halt the action in
process, but it will prevent
initiation of a new sample,
unless the error condition
is corrected.
Stopped - inoperable. Communication error.
Stopped - inoperable. Analyzer fans power supply
defective.
