Graco recommends running the following tests daily.

Mix and Integration Tests

Use the following tests to check for proper mix and inte- gration.

Butterfly Test

At low pressure, normal flow rate, and without a spray tip installed, dispense a 1/2 in. (12.7 mm) bead of material onto foil until multiple changeovers of each pump have occurred. Fold the sheet of foil over the fluid then peel it back and look for unmixed material (appears mar- ble-like).

Curing Test

Spray a single continuous pattern on foil at typical pres- sure setting, flow rate, and tip size until multiple change- overs of each pump have occurred. Trigger and de-trigger at typical intervals for the application. Do not overlap or cross over your spray pattern.

Check curing at various time intervals, listed on the material data sheet. For example, check for dry to touch by running your finger along the test pattern’s entire length at the time listed on the data sheet.

NOTE:

Spots that take longer to cure indicate insufficient inte- gration.

Appearance Test

Spray material onto metal substrate. Look for variations in color, gloss, or texture that may indicate improperly catalyzed material.

Pump and Metering Test

This test checks the following four items and should be run every time a new job is started, or if there is a sus- pected problem.

•Verifies that the pumps installed match the pumps selected on the Setup screen by dispensing exactly 750 ml of each material.

•Verifies that each pump holds fluid against the pump inlet valve by stalling on the down stroke.

•Verifies that each pump holds fluid against the pump piston valve and packings by stalling on the upstroke.

•Verifies that each metering valve holds fluid, and that there are no external leaks between the pump and metering valve.

•Verifies that the recirculation valves (AC, AD) are closed and do not leak.

This test will dispense 750 ml of component A, and then 750 ml of component B. Dispense into separate cups so the fluid can be returned to the supply tanks.

NOTE:

During each dispense the flow will stop once to stall the upstroke, once to stall the downstroke, and then it will finish the dispense. Do not close the sampling valve until the third flow stops and the blue pump light (DK) goes out.

1.Enter Test mode in the run (fluid control) screen.

See Test Screens on page 71. Select to run pump test.
