Warning Code Warning Message Description and Remedial Action

15014 Evaporation heater

fault

The evaporation heater has failed to apply the selected

temperature.

Turn the detector off and on. Test the evaporation heater by

the self test. Allow the detector to come to thermal

stabilization. If the heater still fails, contact Service.

Error Codes

The following table lists the detector-related error codes and messages along with

recommended remedial actions. Error codes immediately result in the interruption of data

acquisition from the detector and will terminate any automates sequences or batch runs when

you operate the detector from a chromatography data system.

If left unattended, error codes may result in permanent physical damage to the detector.

Note the error code or the exact wording of the message and contact the Thermo Fisher

Scientific Service for Dionex HPLC products if you are unable to eliminate the problem.

Error Code Error Message Description and Remedial Action

29006 Low gas pressure The gas pressure has dropped below 241 kPa (35 psig). This can be

caused by an incorrect gas pressure setting: a gas leak (internal or

external), or an incorrect gas supply pressure.

The contact closure was sent to the Digital I/O terminal of the

detector. If a pump is connected to the Digital I/O, the pump flow

will be stopped. On the detector display, press any soft key to

continue.

Corona Veo RS only: The stream-switching valve will divert liquid

flow away from the nebulizer to prevent detector flooding.

Check that

• gas supply pressure is in the range of 480 kPa – 550 kPa

(70 – 80 psig) and that gas is still being delivered to the

detector.

• gas pressure reading on the detector display is the range of

276 kPa – 448 kPa (40 – 65 psig).

• gas supply tubing is correctly installed at the rear of the

detector and that there are no signs of a gas leak.

• gas filters are correctly installed and that there is no sign of

gas leakage.

Turn the detector off and on and allow the self test to test the

pressure sensors. If the error persists, contact Service.
