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 semi-automatic systems only).
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
F
IG
. 109 through F
IG
. 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.
