OI/ASO550–EN Rev. G
Possible cause and suggested action
NV error – software key 1 (CRC Comms.)
Failure of non-volatile memory on software key 1 board or permanent corruption of its data.
Cycle power to the device.
If problem persists check all configuration parameters and correct any errors.
If problem still persists contact local service organization.
Temperature sensor failure for wet-section1 (2, 3, 4).
The temperature compensator or associated connections are either open-circuit or short-circuit.
Check wiring temperature compensator connections to the PCB.
Calibrating.
Displayed during calibration of wet-section (1, 2, 3, 4).
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
Wet-section(s) performing a recovery stage after calibration, regeneration, or after exiting Man.Valve Control –
see page 47.
During the recovery period, outputs and alarms are held if Hold Outputs is enabled – see page 45.
A regeneration routine is being run.
Refer to Section 5.7, 28 for details of this routine.
The analyzer is operating in Simulation mode.
Last wet-section calibration failed.
Check reagent is entraining (bubbles at end of entrainment tube, check reagent is fresh).
Check the calibration solution.
Sample flow rate is less than 50 mlmin.(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 10,000 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.
key, scroll to Manual Hold and select the appropriate wet-section(s).
