Description

For integral color change systems only: During the execution of a color change cycle, the color enable output and the Purge Solvent output are not allowed to be ON at the same time. If the color change cycles attempt to do this, the cycle is aborted. (This is to prevent contamination of the paint lines.)

Remedy

Check the cycle data table and make sure the color enable and Purge Solvent outputs are never ON at the same time.
