8.3 Operating Problems
This section is a guide to troubleshooting issues that may arise during
operation of the Vanquish charged aerosol detector.
8.3.1 Resolving Leakage
When
The leak sensor is wet. The leak sensor reports leakage.
Parts required
Replacement part as required
Additional items required
Cloth or tissue
Preparations
When resolving leakage, observe the safety guidelines and general rules
for maintenance and service as presented in
chapter 7 Maintenance and
Service, page 115 .
Follow these steps
1. Locate the source of the leak.
As leakage usually occurs at a connection, visually inspect all
components and connections in the flow path.
If liquid is visible on the nebulizer, leakage may have occurred in the
nebulizer. Remove the nebulizer from the detector (see
section 7.7,
page 128 ). Inspect the nebulizer for signs of leakage.
♦
If no signs for leakage are present, re-install the nebulizer (see
section 5.5.3, page 62 ).
♦
If signs of leakage are present, proceed with the steps below.
2. Tighten or replace the connection or component as required.
3. With a cloth or tissue, thoroughly absorb all liquid that has collected
in the leak tray and under the leak sensor. Be careful not to bend the
sensor.
4. Allow the sensor to adjust to the ambient temperature for a few
minutes.
5. If leakage is no longer reported, you can resume operation.
