Possible cause and suggested action
Temperature sensor failure for wet-section1 (2, 3, 4).
The temperature compensator or associated connections are either open-circuit or short-circuit – check
wiring at temperature compensator connections to the PCB.
Calibrating.Displayed during calibration of wet-section (1, 2, 3, 4), when wet-section is exposed to air.
On a multiple wet-section setup, this inhibits other wet-sections being calibrated.
Wet-section (1, 2, 3, 4) in manual hold mode via front panel.
Analog outputs and alarms are held. To exit manual hold press the
select the appropriate wet-section(s).
Wet-section(s) performing a recovery stage after calibration, regeneration, or after exiting Man. Valve
Control – see page 41.
During the recovery period, outputs and alarms are held if Hold Outputs is enabled – see page 40
The analyzer is operating in Simulation mode.
Last wet-section calibration failed.
Check the calibration solution – refer to Appendix A.3, page 65.
Sample flow rate is less than 50 ml/min (3.05 cu in./min)
Increase the sample flow to the wet-section.
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.
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).
Reduce the temperature of the sample.
No sample available at wet-section.
.Displayed only if Solution Detection is enabled.
Note
Memory card is more than 90% full.
Replace memory card.
