Color Change Procedures
Multiple Color Systems
1.Shut off air to the gun.
2.Place the gun in the gun flush box if used, and close the lid.
3.Go to Standby mode (remove Mix input).
4.Select the new recipe. Begin the color change sequence.
5.If a gun flush box is not used, trigger
the gun (manual or automatic) into a grounded metal pail until the color change sequence is complete.
NOTE: The color change timer does not start until a Gun Trigger input is seen and fluid flow is detected. If no flow is detected within 2 minutes, the color change operation aborts. The system enters
Standby | mode (remove Mix input) at the previ- |
ous color.
6.When you are ready to spray, remove the gun from the gun flush box if used, and close its door (manual and
NOTE: The gun flush box door must be closed for the atomizing air valve to open.
7. Enter Mix | mode to start spraying. |
Single Color Systems
1.Follow procedure for Purging Fluid Supply Sys- tem, page 96.
2.Load the new color. See Start Up, page 89.
3. Enter Mix | mode to start spraying. |
Color Change Sequences
FIG. 109 through FIG. 126 illustrate various color change sequences. See Table 15 to determine which figure to reference, based on the recipe change and system con- figuration. The time sequences are detailed in the fol- lowing paragraphs.
NOTE: For software version 2.04.xxx and older, the sys- tem uses the color/catalyst purge and fill times from the new recipe.
NOTE: See Setup Mode on page 28 to select purge sources and set desired purge, chop, and fill times.
NOTES:
•The system uses old recipe data for the purge cycle. However, it opens the new color/catalyst valve based on the new recipe data.
•The system uses the new recipe data for the fill cycle.
•For the one gun flush box (GFB) option, the spray gun must be inserted in the GFB during the entire color change cycle (purge and fill). The GFB trigger output will be on during the recipe change cycle.
•For the two gun flush box (GFB) option, both spray guns must be inserted in the GFBs during the entire color change cycle (purge and fill). The system will turn each GFB trigger output on and off based on the preset time for each gun.
•For Special Outputs options, the system will turn each output on and off based on the preset times. Each Special Output has two different start times and durations.
•For systems without dump valves, the First Purge begins after the Color/Catalyst Change steps are completed.
•Dump Valve B is required for a Catalyst Change system.
•When going from Recipe X to Recipe 0, only the purge cycle data from Recipe 0 is used.
•When going from Recipe 0 to Recipe X, only the fill cycle data from Recipe X is used.
