7.2 Connection of Column Data Tags
When the switching valve is mounted, the column management
system updates the history data of the columns used in the
analysis, interlocked with the switching valve, each time an
analysis is completed, suspended and brought into an abnormal
end.
To ensure that the history data of the columns used in the
analysis are properly updated, connect the column data tags to
each appropriate slot according to the figure below.
The tag connected to an inappropriate slot will prevent correct
history data management.
A-1 G-1
A-2 G-2
A-3 G-3

(1) Where No Switching Valve is Used
Where the column management system is used in the
Chromaster 5310 column oven which is set not to use a
switching valve, the data on the tags which are connected
to the A-1 slot (for analysis column) and the G-1 slot (for
guard column) as shown in the figure above will be updated.
No data on the tags connected to other slots will be
updated.
