Excess Liquid and Leak Detection

As leaks are a potential safety issue, sensors in the charged aerosol
detector monitor the following:
The liquid sensor monitors the detection flow path and detects
accumulated solvent. When excess liquid is present, the liquid sensor is
triggered.
When the liquid sensor detects excess liquid (flooding) inside the
detector, the status indicators change to red and beeping starts to alert
you. The Chromeleon software automatically stops the pump flow and
issues a message in the Audit Trail. Follow the instructions in this manual
to eliminate the excess liquid.
The leak sensor inside the device monitors the device for liquid leaks
from the flow connections. The liquid is collected in the leak tray and
guided to the drain port. From the drain port, the liquid is discharged to
waste through the drain system of the Vanquish system.
When the leak sensor detects leakage, the status indicators change to
red and beeping starts to alert you. Follow the instructions in this
manual to find and eliminate the source for the leakage.
