Phasing Adjustment

FIG. 6: Phasing Calibration Screen.

When the machine executes a shot, materials from Tank A and Tank B enter the static mixer where they are mixed and then dispensed. In order for the materials to mix at the desired ratio, both materials must enter the static mixer at the same time. The timing of the materials entering the static mixer is dependent on the adjustment of the phase adjustment screw for each piston.

Prepare the Machine

1.Place a waste container under the dispense valve to catch dispensed material.

2.Remove the static mixer from the dispense valve.

3.Install the ratio check nozzle onto the dispense valve.

8.Adjust the displayed percentage if more than a cou- ple drops of either material was dispensed or if no material was dispensed from both sides.

•If too much material was dispensed, decrease the phasing percentage. If necessary, use the arrow keys to switch the percentage from posi- tive to negative.

•If no material was dispensed, increase the dis- played percentage. If necessary, use the arrow keys to switch the percentage from negative to positive.
