Prime the Valve
1.
Connect the material syringe or the material line.
2.
Make sure the material supply pressure is on or set to “
SUP
”.
3.
Set the material supply pressure to 5 psi.
4.
Examine the fluid reservoir, connections, and valve for leaks.
Set Fluid Pressure
1.
Use Portal to set the valve to open.
2.
Start at 5 psi and increase the fluid pressure until a steady stream or a
continuous flow of dots exits the nozzle. Fluids react differently, some may curl
up or pool at the nozzle outlet.
3.
Once the necessary flow is achieved, use Portal to close the valve.
Set Jet Pressure
Jet pressure is the force that pushes the fluid out of the jet when it is dispensed. Too
little jet pressure, and the fluid will not leave the nozzle completely and accumulate on
the nozzle. Too much jet pressure, and the fluid will have satellites or splatter when it
hits the surface of the product. The jet pressure must be set between 45-65 psi to work
correctly.
1.
Set the operating air pressure at 45 psi to start.
2.
Dispense the material and examine the nozzle and surface that was dispensed
on for buildup, splatter, or satellites.
3.
Adjust the jet pressure until the results are correct.
NOTE: The maximum jet pressure is 65 psi.
Shutdown
•
Release the pressure in the system, refer to the workcell manual for additional
information.
