F011
No sparger flow
Loss of sample or acid
In cases where the sample composition is not
optically homogeneous, false triggering cannot
be avoided and the flow sensing should be
disabled in the Service\Input status screens.
In later firmware versions, this may require
setting the flow failure thresholds to 0.
Ensure no leaks in acid line due to either tubing
or fittings.
Verify sample is flowing to the analyzer.
F02*
No UV lamp flow
In cases where the sample composition is not
optically homogeneous, false triggering cannot
be avoided and the flow sensing should be
disabled in the Service\Input status screens.
In later firmware versions, this may require
setting the flow failure thresholds to 0.
Loss of persulfate. Check persulfate supply.
Loss of resample. Ensure no leaks in resample.
F03*
No carrier gas
The pressure switch has detected low carrier
pressure.
Verify carrier gas presence.
Replace pressure switch.
