Calibration Failed
The analyzer has failed calibration.
1. Check that the reagents are of the correct type, connected
correctly (Reagent 1 to valve R1 etc.) and are within their shelf life.
If it is possible that the reagents have become contaminated
replace them.
2. Check that the calibration settings are correct.
3. Check for any restrictions or blockages in the analyzer tubing or
valve manifold.
4. Check that each reagent/sample is drawn into the measurement
head correctly with no air bubbles.
5. Check the optical cell for any scratches.
If the error still exists contact the local ABB representative.
Calibration Failed
The analyzer has failed calibration.
If the Calibration Fail Event has been set to Attention from the default Fail,
the analyzer continues to measure after a failed calibration using the last
valid calibration.
Calibration Standard Empty
The calibration standard bottle is empty.
Replace the calibration solution.
Cleaning
A clean routine is being run.
Critical Temperature Reached
This alarm is initiated if the analyzer temperature rises above 60 °C
(140 °F) during temperature control.
1. Check that the ambient temperature limits have not been
exceeded.
2. Contact the local ABB representative.
DI Empty
The de-ionised water bottle is empty.
 Replace the de-ionised water.
Excessive Secondary Current in Electronics
Too much current is being drawn by the electronics in the system; this
causes the analyzer to go into automatic shutdown.
 Contact the local ABB representative.
