8.4 Eliminating Leakage
The leak sensor is installed on the interior front panel of the detector (→ Fig. 2, page 19).
The sensor reports a leak when liquid collects in the drip tray under the flow connections.
Eliminate the cause for the leakage and dry the leak sensor.
1. Stop the pump flow. If you operate the detector from a chromatography data system,
disconnect the detector from the software.
2. Turn off the detector.
3. Inspect the capillary connections on the detector for signs of leakage:
♦ Nebulizer
Check the capillary connection to the nebulizer for signs of leakage.
♦ Corona Veo RS only
Check the stream-switching valve for signs of leaks on the capillary connections from
the column, to the nebulizer, and to "Divert" (waste).
4. With a cloth or tissue, absorb all liquid that has collected in the tray.
Important: Make sure that you do not bend or damage the sensor.
Important: Assurez-vous que vous ne tordez, ni n'endommagez le
capteur.
5. Allow the sensor to adjust to the ambient temperature for a few minutes.
6. Turn on the detector and, if applicable, reconnect it with the chromatography software.
7. If no error is reported after you turned on the detector, you can resume operation.
Tip: If the sensor is not dry, the display continues to show a warning code.
