Encore Automatic PE Powder Spray Gun20Part 1612502−01  2018 Nordson CorporationCorrective ActionPossible CauseProblem2. Voids in powderpatternWorn nozzle or deflector Remove and inspect the nozzle ordeflector. Replace worn parts.Plugged electrode support orpowder tubeRemove the electrode support andclean it. Remove powder tube ifnecessary and clean it.Electrode air-wash flow too high Air-wash flow is controlled by a fixedorifice. Refer to your controllermanual for more troubleshootinginformation.3. Loss of wrap, poortransfer efficiencyLow electrostatic voltage Increase the electrostatic voltage.Poor electrode connection Remove the nozzle and electrodesupport. Clean the electrode andcheck for carbon tracking or damage.Check the electrode supportresistance as shown on page 22. Ifthe electrode support is good,remove the gun power supply andcheck its resistance as shown onpage 22.Poorly grounded parts Check the conveyor chain, rollers,and part hangers for powder buildup.The resistance between the partsand ground must be 1 megohm orless. For best results, 500 ohms orless is recommended.4. No kV output from thespray gun (displayshows 0 kV when guntriggered), but powderis sprayingDamaged gun cable Perform the Gun Cable ContinuityChecks on page 23.If an open or short is found, replacethe cable.Spray gun power supply shorted Perform the Power SupplyResistance Test on page 22.5. No kV output from thespray gun (interfaceshows kV output) butpowder is sprayingSpray gun power supply open Perform the Power SupplyResistance Test on page 22.Damaged gun cable Perform the Gun Cable ContinuityTest on page 23.If an open or short is found, replacethe cable.6. Powder build up onthe electrode tipInsufficient electrode air-wash flow Air-wash flow is controlled by a fixedorifice. Check the air-wash tubing,and check for flow at the output fittingwhen the gun is triggered on. Referto your controller manual for moretroubleshooting information.Continued...
