Override Mode
The analyzer is in Override Mode.
Normal running has been overridden by the operator.
The Override Mode is useful to check analyzer operation manually.
The analyzer remains in Override Mode until it is stopped.

Flushing
The analyzer is in flushing mode.
This facility carries out a continuous routine but does not store or display
measurement values.
The routine can be used without a prior calibration and is useful when a
analyzer is swapped from one parameter to another.
The analyzer remains in flushing mode until it is stopped.

A / D Error
A hardware error exists on the main board.
Power the analyzer down, wait for 10 seconds and power-up again.
If the error persists, contact the local ABB representative.

Calibration Failed
'Calibration Fail Event' set to 'Fail' (see Section 6.3.1, page 35)
'Calibration Fail Event' set to 'Attention' (see Section 6.3.1, page 35) or
Calibration Failed with Probe Stability Failure
Note.
If 'Calibration Fail Event' is set to 'Attention', the analyzer
continues to measure after a failed calibration using the last valid
calibration.
The analyzer has failed calibration. Check that:
1.
the reagents are of the correct type, connected correctly and are
within their shelf life. If it is possible that the reagents have become
contaminated replace them.
2.
the calibration settings are correct.
3.
there are no restrictions or blockages in the analyzer tubing.
4.
each reagent / sample is drawn into the measurement head
correctly.
5.
the electrode is connected correctly.
If the error persists, contact the local ABB representative.
