JDX PVA Safety Certain warning symbols are affixed to the machine and correspond to notations in this manual. Before operating the system, identify these warning labels and read the notices described below. Not all labels may be used on any specific system.
The unique diaphragm design allows for fast cycling of the jet, up to 300Hz for high speed line dispensing. The JDX is designed to dispense coatings, underfill, encapsulant, SMT glue, grease, and more with very fine control.
JDX PVA Necessary Tools PVA offers tools and cleaning accessories to maintain the JDX jet valve. Part Number Description 02597 3mm hex wrench Philips screwdriver Setup Before you operate the jet, know the components. Follow the steps instructed below for safe and correct operation.
It is not necessary to remove the jet valve to do the procedures. Install the Diaphragm 1. Set the jet valve to open with the operator interface of JDX controller box. 2. Align the ribs on top of the diaphragm to the groove features on the bottom of the heater block.
JDX PVA Install Nozzle Plate and Feed Tube 1. Align the feed tube with the barb inlet on the nozzle plate. 2. Push the feed tube onto the barb inlet. Figure 4: Feed Tube and Nozzle Plate 3. Align the nozzle plate on the heater block with the barb inlet facing toward the syringe bracket.
JDX PVA 5. Use a hex wrench to tighten the recessed screws in the two holes shown. Turn the screws clockwise until they are tight and the nozzle plate does not move. Figure 7: Tighten the Screws to Attach the Nozzle Plate 6.
JDX PVA Prime the Jet 1. Set the jet to close with the operator interface or JDX controller box. 2. Fill the syringe with material. 3. Attach the air cap to the syringe. Figure 9: Attach the Air Cap 4. Set the supply pressure to 10 psi.
The fluid pressure supplies the material to the jet chamber to keep the drop size correct and consistent. Higher fluid pressure is usually better. 1. Set the jet to open with the operator interface or JDX controller box. 2. Start at 10 psi and increase the fluid pressure until a steady stream or a continuous flow of dots exit the nozzle.
JDX PVA 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 material will accumulate on the nozzle. Too much jet pressure and the fluid will have satellites or splatter when it hits the surface of the product.
JDX PVA 5. Loosen and remove the feed tube off of the syringe. 6. Remove the syringe. Figure 11: Remove the Syringe 7. Use a 3mm hex wrench to loosen the two recessed screws and remove the nozzle plate. Figure 12: Remove the Nozzle Plate 8.
JDX PVA Clean the Wetted Parts 1. Clean the diaphragm with cotton tipped swabs and solvent. Figure 13: Clean the Diaphragm 2. Remove the feed tube from the nozzle plate and discard it. 3. If necessary, soak the nozzle plate in ultrasonic cleaner for 5 minutes.
JDX PVA Replace the Orifice 1. Loosen the three screws in the nozzle plate. Figure 15: Remove the Nozzle Plate Screws 2. Remove the barb plate. Figure 16: Remove the Barb Plate 3. Remove the O-ring from the barb plate. Clean and replace as necessary.
JDX PVA Figure 18: Barb Plate and Orifice O-rings 4. Remove the orifice (the orifice shown is ceramic; you may have a different orifice). You may have to turn the nozzle plate over and push on the orifice tip to remove the orifice.
JDX PVA Figure 21: Install the Barb Plate 8. Turn the nozzle plate over and install the three screws. Make sure the screws are correctly tightened. Do not damage the screws when you tighten them Figure 22: Install the Nozzle Plate Screws 9.

JDX PVA Maintenance Interval Action Daily • Examine the material outlets for contamination and cured material. Weekly • Examine material containers or cartridges for signs of cured or dried material. Shutdown • Flush or clean the system. • Clean or replace the nozzle plate, diaphragm, and feed tube.
How to Use the Valve with Portal If your valve is on a workcell with PVA Portal, use the screens that follow to operate the valve. Refer to the Portal manual for additional information on how to use the program.
JDX PVA Figure 27: JDX Setup Options 4. Double click on any parameter to open an edit window. NOTE: Most settings for the Jet Valve are set with the PVA JDX Jet Valve Controller. Figure 28: JDX Parameter Edit Windows 5.
To select a recipe in Manual mode do the steps below. 1. Select Manual Mode. 2. Select the Valves tab. 3. Click on the Select Valve drop down menu, and select a recipe for the JDX valve. A screen will show that the parameters are loading. Figure 29: Valves Tab NOTE: The settings are found in the tabs shown when you select the Jetter tab.
JDX PVA Jetter Maintenance 1. Select “Manual” from the cycle stop screen. 2. Select the “Jetter” tab. Figure 30: Jetter Maintenance 3. Select the Clean Jetter “Go” button to move the valve to the vacuum cup 4. Select the Vacuum “ON” and “OFF” buttons to turn the vacuum on and off.
How to Use the Jet with the PVA JDX Jet Valve Controller If your valve is on a workcell with the PVA JDX Jet Valve Controller, use the screens that follow to operate your valve. Figure 31: PVA JDX Jet Valve Controller Front Panel 1.
JDX PVA Figure 32: PVA JDX Jet Valve Controller Rear Panel 12. Air inlet – This port should be connected to the source pressure with a 6mm diameter hose. 13. Jet Pressure outlet – This port provides air pressure for the jet dispenser and should be connected with a 6mm diameter hose.
JDX PVA Jet and Fluid Pressure The PVA JDX Jet Valve controller has integrated air regulators (7, 10) which control the pressure to the Jet and the Fluid supply. Two digital gages (2, 6) show the pressure levels. The Fluid Pressure can be turned off with the air switch (11).
JDX PVA 6.2.2 To turn ON the heater 1. Press the INDEX key until you see the Run-Stop Output Control screen (r-5) on the top line of the display. 2. Now use the arrow key to select run setting to turn ON the heater as shown by the figure below.
JDX PVA LCD Display Functions and Selection Keys There are 8 settings available on the main LCD menu. The UP/DOWN keys are used to change the values in the settings.
