Adjust B Machine Outlet Restriction

Adjust the restriction stem on mix manifold, or on restric- tor valve if mix manifold is remote, to optimize the B side dosing control window. The goal is to create a near con- stant flow on the A side and frequent dosing or a near constant flow on the B side.

1.With material at normal spray temperature and tip installed on spray gun, trigger gun for at least 10 seconds.

2.Navigate to Ratio Mode screen. See Ratio Mode, page 71. Check bar graph.

The ratio bar graph is shown when is pressed. This screen is used to show the accuracy of the spray ratio. The bar should be in the center three segments when the restrictor is adjusted.

3. Press to go to the restrictor adjustment screen.

Adjust B Machine Outlet Restriction

NOTE:

•For remote mix manifolds, set the machine restrictor first. Then close the remote mix manifold restrictor to approximately the same setting, or until the restrictor screen starts to move to the left.

•It is normal for the bar to move on the graph while spraying. If the adjustment is too far off, you will receive an alarm. If the ratio will not hold, you will receive alarm R4B or R1B. See Alarm Codes and Troubleshooting, page 52.

•If the bar swings back and fourth and you are using feed pumps, the feed pressure may be too high. Keep feed pressure under 250 psi (1.75 MPa, 17.5 bar). High pressure pumps receive a pressure boost that is twice the pressure feed on the upstroke only. High feed pressures can cause pressure swings between A and B. The system will compensate, but the bar graph will the show the swing.

Resin dosing size

Combined flow rate

The restrictor adjust bar graph is shown when is pressed. This screen is used to adjust the restrictor.

•At maximum fluid flow, the bar should be in the cen- ter.

•At flows less than maximum, the bar should be on the right side.

•The bar should never be on the left.

•Configure the system at maximum fluid flow. Then turn the restrictor clockwise if the bar graph is on the right and counter-clockwise if the bar graph is on the left.

NOTE: A pump dosing size, shown on the upper left cor- ner, will be minimum when the restrictor is adjusted cor- rectly. Once the restrictor is set for a given ratio and material, it should be locked in place and left alone.
