Use this spreadsheet to enter your time program. The number of columns
corresponds to the number of configured valves in the system. In the first
row (at time 0.00), enter the initial position for each valve. Then you can
define the states of the valves at the given time.
The choices for a Knauer 2-position valve are BLANK and L (Load) and I
(Inject), for a Vici 2-position valve BLANK and A (Load) and B (Inject), 1
through 6 for a 6-position valve, 1 through 8 for a 8-position valve, 1
through 10 for a 10-position valve, 1 through 12 for a 12-position valve
and 1 through 16 for a 16-position valve. The BLANK space means that
the valve will not change its state at the given time.
You can enter the settings either by typing the desired values into the
corresponding field or by selecting your choice from the pull down menu
which becomes accessible via the button, appearing in the selected
field.
For details on the spreadsheet operations, refer to the section Creating a
Time (Gradient) Program as described in the chapter Instrument Setup –
Pumps, Pump Program.
The valves program profile will be adapted automatically to the
spreadsheet inputs when you save the method.
If you select any field in the comment column the button will appear,
to open a comment window.
