System Operation
Systems with Color Change and without Dump Valves
NOTE: This procedure relieves pressure through the sampling valve.
1.Complete all steps under Single Color Systems, page 91.
2.Close the A side shutoff valve (SVA), FIG. 106. Open the A side sampling valve (RVA).
3.Direct the A side sampling tube into a waste con- tainer.
4.See FIG. 105. Open the color change module. Using the solenoid identification labels as a guide, press and hold the override button on each color solenoid until flow from the sampling valve stops.
5.Press and hold the solvent solenoid override until clean solvent comes from the sampling valve, then release.
6.Shutoff the solvent supply to the color change stack solvent valve.
7.Press and hold the solvent solenoid override until solvent flow from the sampling valve stops.
8.Open the A side shutoff valve (SVA), FIG. 106. Close the A side sampling valve (RVA).
Systems with Color/Catalyst Change and Dump Valves
NOTE: This procedure relieves pressure through the dump valves.
1.Complete all steps under Single Color Systems, page 91.
2.Shut off all color and catalyst supplies to the valve stacks.
3.Press and hold the dump valve A solenoid override, FIG. 104.
4.See FIG. 105. Open the color change module. Using the solenoid identification labels as a guide, press and hold the override button on each color solenoid until flow from dump valve A stops.
5.Press and hold the dump valve B solenoid override, FIG. 104.
6.See FIG. 105. Using the solenoid identification labels as a guide, press and hold the override but- ton on each catalyst solenoid until flow from dump valve B stops.
7.Press and hold the dump valve A solenoid override, FIG. 104.
8.Press and hold the A side (color) solvent solenoid override until clean solvent comes from the dump valve, then release.
9.Press and hold the dump valve B solenoid override, FIG. 104.
10.Press and hold the B side (catalyst) solvent solenoid override until clean solvent comes from the dump valve, then release.
11.Shutoff the solvent supply to the color/catalyst change stack solvent valves.
12.Press and hold the A and B solvent solenoid over- rides and dump valve overrides until solvent flow from the dump valves stops.
