Message and Code Description and Remedial Action
Code 6010 Nebulizer gas
pressure too high. The nebulizer gas pressure has exceeded the maximum limit.
The detector gas flow and the pump flow are automatically stopped. The
drain pump remains turned on for a short period longer and is then turned
off.
• Make sure that gas is still supplied to the detector. Check that the gas
supply pressure is within the allowed range. See the
Gas specifications
in
section 9.1, page 164 .
•
If the gas supply pressure exceeds 620 kPa (6.2 bar, 90 psi), the
overpressure relief valve will open. This creates a loud hissing sound. To
remedy the gas supply overpressure, see
section 8.3.2 Resolving Gas
Supply Overpressure, page 159.
• Check that the nebulizer gas pressure is set as specified on the nebulizer
gas pressure certificate.
•
Check the gas inlet tubing and gas filter assembly for proper connection to
the detector.
• Turn the detector off and on. Check the self-test results.
If the message persists, contact Technical Support.
Code 6011 Detection chamber
flooded. Stop pump
immediately. Excess liquid is present inside the detector.
The detector gas flow and the drain pump are automatically turned on and
the pump flow is stopped.
See
section 8.3.3 Resolving Flooding In the Detector, page 160 .
Code 6031 Data transfer error
from detector to PC – check
USB connection. Check the USB connection. Test the transmission speed of the data source
(the network may be too slow).
Code 6032 Data transfer error
from detector to PC – check
USB connection. Check the USB connection. Use only the USB cables provided by Thermo
Fisher Scientific for the detector. Avoid CPU-intensive and time-consuming
operations on the PC during high-speed data acquisition.
