Using Recipes/Color Change
Changing from One Color Change
Sequence to Another
It is possible to perform a color change from a recipe
associated with one color change sequence to a recipe
that is associated with another color change sequence.
In this case the system automatically uses the old
sequence for dumping and purging and the new
sequence for loading and mixing. This type of color
change is useful in applications where one material
tends to purge and load more quickly than another.
When switching from one sequence to another, there
are two transition points that determine which
sequence is being used at a given time. The first
transition point occurs when the solvent valve for the
color change stack closes. The second transition point
is when the purge is complete. The table at right lists
the outputs associated with the transition points.

An example of a color change from one sequence to another is as follows.
Sequence 1:
Purge time = 20 Seconds
Mix time = 20 seconds
Component A Dump time = 7 seconds
Component A Solvent time = 5 seconds
Special 1 on time = 0 seconds
Special 1 time = 40 seconds
Total Sequence Time = 40 seconds
