Step Commands
Some movements of the fraction collection sequence can be done under
manual control. This is useful during troubleshooting where close observation
of each of the fraction collection step is required to confirm a specific failure
mode or verify successful completion of a repair.
Each step command actually consists of a series of individual commands
which move the fraction collector components to predefined positions
enabling the specific step to be done.
In the ChemStation the step commands can be selected from the “Test
Selection Box” (see Figure 22) in the Diagnosis display. In the Control Module
the step commands can be accessed from the pull-down menu in the fraction
collector “Test”.
