8.2.10 System Diagnostics
For the Vanquish system modules, diagnostics features are supported in
the Chromeleon software. With these features, the user can check and
monitor the performance and reliability of certain components.
Manual Testing
You can run the following tests from Chromeleon:
Test Remarks
Basic Tightness Test Depending on the Vanquish system configuration, the
available tests may vary. If a test is grayed out in the
Chromeleon software, the test is currently not
available.
When a test is running, the LED bar on the module
shows a blue running light.
Grating Motor Test
Intensity Test
Shutter Motor Test
Automatic Testing
You can set up a schedule in Chromeleon for automatic testing.
Automatic testing is possible only for tests and functions that can run
unattended, without further user interaction, for example the
Basic
Tightness Test .
Test Failed
To ensure that you run sequences only on fully operational modules, the
Chromeleon software prevents you from starting a sequence if a
diagnostic test has failed. If a test failed, take remedial action and repeat
the test. A user with special control privileges in the Chromeleon
software can override the failed test result. Refer to the
Chromeleon
Help.
