The setup will be similar to that in the pictures below:
Valve Sequencer Software
The Valve Sequencer software allows the user to set steps in which solenoid
valves are turned on/off and the rotary selector valve is set to a single position.
The current step, elapsed duration, and valve states are shown in the top most
row of the valve sequencer command window. The duration of each step is set in
minutes; for example, 1 minute and 30 seconds corresponds to 1.5 minutes.
Please note the number of steps correlates with the total steps in the sequence.
But the count of the steps starts at "0". So, according to the image, the first step
of the sequence is designated Current Step "0" and the second step in the
sequence is designated Current Step "1". The "Go to First Step" menu item under
"Action" restarts the sequence from step 1.
Different sequences can be created and saved in the software. Use the
"Sequence File #" field to select which file the sequence will be saved to (0 to 10
are the available choices). Click the up/down arrows to select the desired
number.
