Color Change

First Purge

Step M0-M1

Select the First Purge Source (air, solvent, or 3rd valve) and First Purge Time. For most applications, air is selected.

The system purges the old material from the dose valves to the gun, using only the selected purge media (usually air). The selected purge valve opens during the First Purge Time and closes when the time expires.

Chop Cycle

Step M1-M2

Select the Chop Type (air/solvent or air/3rd valve) and Chop Times.

The air purge valve opens only during the air chop cycle, and the solvent (or 3rd valve) opens only during the solvent chop cycle. The number of chop cycles is determined by dividing the Total Chop Time by the sum of the Air and Solvent Chop Times.

Final Purge

Step M2-M3

Select the Final Purge Source (air, solvent, or 3rd valve) and Final Purge Time. For most applications, solvent is selected.

The system fills the line with solvent from the dose valves to the gun, using only the selected purge media (usually solvent). The selected purge valve opens dur- ing the Final Purge Time and closes when the time expires.

Fill

Step M3-M4

This sequence fills the line from the dose valves to the gun, and is also referred to as the mixed material fill. The system begins mixing components A and B until the Fill Time expires.

Purge Active

Step M0-M3

The system turns on the Purge/Recipe Change Purge Active output during steps M0-M3.

Fill Active

Step M3-M4

The system turns on the Recipe Change Fill Active out- put during step M3-M4.
