Purge Values
A typical integrated color change sequence starts by
purging out the old mixed material.
The purge is further defined by setting:
purge start time,
total purge time,
purge time for the first cycle,
purge time for the last cycle,
and individual purge times for the three pos-
sible purge valves.
Mix Values
The integrated color change sequence fills the hoses
with the new mixed material after the system has
finished purging. The duration of the mix (fill) time for
the color change sequence must be defined during
color change setup.
