Charged Aerosol Detectors

Corona Veo and Corona Veo RS

Operating Instructions Page 95

7.3 Warning and Error Codes

Each time a fault or error occurs during the operation of the detector, a warning code or

error code appears on the detector display. In this case, the Continue soft key appears on

the display for navigation

If you operate the detector from a chromatography data system, a message will also be

documented in the audit trail of the software.

Warning Codes

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

recommended remedial actions. Warning codes will neither interrupt data acquisition from the

detector nor interfere with automated sequences or batch runs when you operate the detector

from a chromatography data system.

Note the warning 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.

Warning Code Warning Message Description and Remedial Action

15000 Charger voltage

failed

The voltage of the charger approaches the maximum level.

Turn the detector off and on. If the voltage still fails, contact

Service.

15010 Leak sensor fault

detected

The leak sensor has reported a leak.

Check the nebulizer and/or stream-switching valve for signs

of leakage. Dry the leak sensor (→ section 8.4, page 112).

15008 Stream-switching

valve (SSV) failure

Corona Veo RS only

The SSV has failed to rotate. From the System Setup Menu,

manually actuate the valve. If the valve still fails to rotate,

disassemble and inspect the SSV (→ section 8.7.1,

page 116). If the error persists, replace the rotor and stator

(→ section 8.7 , page 116).

15011 High engine

temperature

The internal temperature of the detector is too high.

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.

15012 Low engine

temperature

The internal temperature of the detector is too low.

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.

15013 High evaporation

temperature

The temperature of the evaporation tube is too high. Set a

lower temperature in the specified range (→ section 5.6.3,

page 66).
