Excess Liquid and Leak Detection

Charged Aerosol Detectors Corona Veo (RS) Operating Manual
As leaks are a potential safety issue, sensors in the charged aerosol
detector monitor the following:
• Excess liquid inside the detector gas flow path
The liquid sensor inside the detector detects any liquid that
accumulates inside. When excess liquid is present, the liquid sensor
is activated.
When the liquid sensor detects excess liquid (flooding) inside the
detector,
♦
A critical error code appears on the detector display and beeping
starts to alert you.
♦ The detector will exit the Run Mode.
If you operate the detector from a chromatography software,
the running sequence (or batch) is aborted.
♦
If the Pump Off relay is connected to the pump, the pump will
stop mobile phase flow.
♦
If not already turned on, the drain pump is turned on
automatically.
♦ Corona Veo RS: The stream-switching valve will actuate and
divert the liquid flow away from the detector.
Follow the instructions in this manual to find and eliminate the
source for the leakage.

Liquid leaks
The leak sensor in the leak tray detects liquid leaks from flow
connections. The liquid is collected in the leak tray and guided to the
leak port on the right side of the detector. From the leak port, the
liquid is guided to a waste reservoir.
When the leak sensor detects leakage, a warning code appears on
the display and beeping starts to alert you. Follow the instructions in
the Troubleshooting chapter to find and eliminate the source for the
leakage.
