Memory card is full, no more data can be saved to the card.
Replace memory card.
Missed last schedule calibration.
Process value (PV) measured is out of the specified range of the wet-section.
Low level dissolved oxygen 0 to 20,000 ppb, sodium 0 to 10,000 and hydrazine 0 to 1000 ppb.
Sample solution temperature lower than 5 °C (41 °F).
Increase the temperature of the sample.
Sample solution temperature higher than 55 °C (131 °F).
Low level dissolved oxygen
Reduce the temperature of the sample.
Note. If the sample temperature is above 55 °C (131 °F), the calibration valve is energized to divert the hot sample
directly to drain, as high temperatures can damage the sensor. The calibration valve de-energizes after 30 minutes.
During this 30-minute period the Concentration and Temperature readings in
the Signals View are held.
Sodium / Hydrazine
Reduce the temperature of the sample.
Memory card is more than 90% full.
Replace memory card.
Sodium only
Out of low calibration solution.
Replace low calibration solution or start a 2-point calibration.
. Displayed only if Solution Detection is enabled.
Note
Sodium / Hydrazine
Out of high calibration solution.
Replace high calibration solution or start a calibration.
. Displayed only if Solution Detection is enabled.
Note
Sodium only
Out of regeneration solution.
Replenish solution.
. Displayed only if regeneration hardware is fitted.
Note
Sodium multi-stream only
No sample available at wet-section.
Check sample flow rates are >50 ml/min.
