6 Maintenance

The aerosol leak detection system is inherently reliable, reducing the requirement for
routine maintenance. This section provides information on the schedule of
maintenance to be performed by the user in order to ensure the reliable performance
of the system.
For all maintenance inside of the control console, the system must be powered off
using the shutdown procedure detailed earlier. There are potentially dangerous
voltages inside the console.

This represents an advanced operation of the leak detector and should only be
performed by suitably trained personnel.
In order to ensure that the aerosol leak detection system is reliable over the long term,
an annual service is recommended. This service should be carried out by a Cascade
engineer or a Cascade-trained service engineer.
6.2

Analysis system

The leak detector system is inherently tolerant to high levels of contamination without
a reduction in performance. The comprehensive filtering undertaken within the air
arch ensures that there should be no need to clean any part of the leak detector within
the lifetime of the product.
Maintenance
Perform an air purge of the leak detector's mirrors.
Verify the leak detection performance of the sensor by passing a leaking can
through the sensor (or equivalent test technique).
Inspect and clean the optical gates and reflectors.
Check the pressure settings on the filter/regulators.
Inspect the rejector and ensure it is operating correctly.
Inspect the encoder to ensure the coupling to the line is solid.
Inspect and clean the air arch filter.
Verify that the compressed air supply to the leak detector is within the levels
specified in
Section 1.6: Detailed system specification.
