Gun Setup Gun Setup Grounding When operating the electrostatic gun, any ungrounded objects in the spray area (people, containers, tools, etc.) can become electrically charged. Improper grounding can result in static sparking, which can cause a fire, explosion, or electric shock. Ground all equipment, personnel, object being sprayed, and conductive objects in or close to the spray area. Resistance must not exceed 100 ohms. Follow the grounding instructions below.
Gun Setup • The floor of the spray area: must be electrically conductive and grounded. Do not cover the floor with cardboard or any non-conductive material which would interrupt grounding continuity. • All persons entering the spray area: must wear shoes having conductive soles such as leather, or wear personal grounding straps. Do not wear shoes with non-conductive soles such as rubber or plastic. If gloves are necessary, wear the conductive gloves supplied with the gun.
Gun Setup Check Gun Electrical Grounding 3. Turn off the air and fluid supply to the gun. Follow the Pressure Relief Procedure, page 26. 4. Disconnect the fluid hose. Megohmmeter Part No. 241079 (AA-see Fig. 14) is not approved for use in a hazardous area. To reduce the risk of sparking, do not use the megohmmeter to check electrical grounding unless: 5. Make sure the grounded air hose is connected and the hose ground wire is connected to a true earth ground.
Gun Setup 7. If the resistance is greater than 100 ohms, check the tightness of the ground connections and be sure the air hose ground wire is connected to a true earth ground. If the resistance is still too high, replace the air hose. 8. Using an ohmmeter (AA) measure the resistance between the cabinet ground lug (214) and a true earth ground (CC). The resistance must be less than 100 ohms. Figure 15 Check Cabinet Grounding Flush Before Using Equipment The equipment was tested in fluid at the factory.
Operation Operation Operating Checklist Check the following list daily, before starting the system. ⃞ All operators are properly trained to operate an electrostatic waterborne air-assisted spray system as instructed in this manual. ⃞ All operators are trained in the Pressure Relief Procedure, page 26.
Operation Pressure Relief Procedure 5. Disengage the trigger lock. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment. 1. Turn OFF (O) the ES On/Off switch. 2. Follow the Fluid Voltage Discharge and Grounding Procedure, page 25. 6.
Operation Fill the Fluid Supply 1. Follow the Fluid Voltage Discharge and Grounding Procedure, page 25. 2. Follow the Pressure Relief Procedure, page 26. 3. Open the isolated enclosure door. 4. Remove the pail cover from the pail, holding a rag over the suction tube strainer to prevent any fluid from dripping into the isolated enclosure. Place the cover and suction tube outside the enclosure. 6. Clean up any fluid spills in the enclosure, using a soft cloth and a non-flammable, compatible solvent. 7.
Operation Adjust the Spray Pattern To reduce the risk of fire and explosion, fluids used must meet the following flammability requirements: • FM, FMc Approved: Material does not sustain burning in accordance with the Standard Test Method for Sustained Burning of Liquid Mixtures, ASTM D4206. • CE-EN 50059 Compliant: Materials which cannot be ignited, in any mixture with air, by an energy source of less than 500mJ. Contact with the charged components of the spray gun will cause an electric shock.
Operation 3. Check gun resistance. See Test Gun Resistance, page 36. 11. Close the atomizing air adjustment valve (G) and the fan air adjustment valve (F). 4. Follow all steps under Grounding, page 21. 12. Check that the ES On-Off switch is OFF (O). 5. Follow all steps under Check Gun Electrical Grounding, page 23. Reading must be less than 100 ohms. 6. Connect the exhaust tube and secure with the clamp provided. 13. Start the pump. Set the fluid regulator to 400 psi (2.8 MPa, 28 bar). 7.
Operation 16. Check that the ES indicator (Hz indicator on Smart guns) is lit, or check that the kV indicator on the isolated enclosure reads 30–50 kV. The actual spraying voltage for AA waterborne systems is 40–50 kV, but because the charging electrode does not directly contact the fluid, the voltage measured by the WB3000 kV meter will be 5–10 kV lower. See the following table. 18. Turn the atomizing air adjustment valve counterclockwise until any tails disappear. Table 2 .
Maintenance Maintenance Flushing • Flush before changing fluids, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment. 1. Turn OFF (O) the ES On-Off switch. Wait 30 seconds for the voltage to bleed off. • Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary. • Flush with a non-flammable solvent that is compatible with the fluid being dispensed and the equipment wetted parts. 2. Discharge the system voltage.
Maintenance 7. Follow the Pressure Relief Procedure, page 26. Engage the trigger lock. 10. Open the isolated enclosure door.

Electrical Tests Electrical Tests Use the following procedures to test the condition of the power supply and gun body, and electrical continuity between components. NOTICE The gun body resistor cartridge is part of the body and is not replaceable. To avoid destroying the gun body, do not attempt to remove the body resistor. Use megohmmeter Part No. 241079 (AA) with an applied voltage of 500 V. Connect the leads as shown. Test Gun Resistance 1. Flush and dry the fluid passage. 2.
Electrical Tests Test Power Supply Resistance 1. Remove the power supply (11). See Power Supply Removal and Replacement, page 52. 2. Remove the alternator (15) from the power supply. See Alternator Removal and Replacement, page 53. 3. Measure resistance from the power supply's ground strips (EE) to the spring (11a). The resistance should be 90–115 megohms. If outside this range, replace the power supply. If in range, go to Test Gun Barrel Resistance, page 38. 4.
Electrical Tests Test Gun Barrel Resistance 1. Insert a conductive rod (B) into the gun barrel (which was removed for the power supply test) and against the metal contact (C) in the front of the barrel. 2. Measure the resistance between the conductive rod (B) and the conductive ring (9). The resistance should be 10–30 megohms. If the resistance is incorrect, make sure the metal contact (C) in the barrel and the conductive ring (9) are clean and undamaged. 3.
Electrical Tests Test Ground Strip Resistance Test Cylinder Resistance Using an ohmmeter, measure the resistance between the latch housing (206) and the ground lug (214). The ground strip is grounded through the cart back to the ground lug. Resistance must be less than 100 ohms. If greater than 100 ohms, replace the ground strip (240). Remove the enclosure door. Using an ohmmeter, measure the resistance from the pump (209) to the ground lug (214). Resistance must be less than 100 ohms.
Troubleshooting Troubleshooting are electrically connected through the conductive, waterborne fluid. Installing and servicing this equipment requires access to parts which may cause an electric shock or other serious injury if the work is not performed properly. Do not install or service this equipment unless you are trained and qualified. Follow the Fluid Voltage Discharge and Grounding Procedure, page 25 before checking or servicing the system and whenever you are instructed to discharge the voltage.
Troubleshooting Visual Checks First, check the system for any visible faults or errors to help isolate whether the spray gun, fluid hose or voltage isolation system has failed. A voltage probe and meter, part no. 245277, is helpful for diagnosing voltage problems and is required for some of the troubleshooting tests that follow. 1. Check that all of the air and fluid tubes and hoses are properly connected. 2. Check that the voltage isolation system valves and controls are properly set for operation. 3.
Troubleshooting Tests If you still have no voltage, separate the spray gun and hose from the voltage isolation system and check whether the gun and hose alone will hold voltage with the following test. 1. Flush the system with water and leave the lines filled with water. 2. Discharge the system voltage (see Fluid Voltage Discharge and Grounding Procedure, page 25). 3. Follow the Pressure Relief Procedure, page 26. 4. Disconnect the fluid hose from the voltage isolation system.
Troubleshooting Spray Pattern Troubleshooting NOTE: Some spray pattern problems are caused by the improper balance between air and fluid. Problem Cause Solution Fluttering or spitting spray. No fluid. Refill supply. Air in fluid supply. Check fluid source. Refill. Fluid buildup; partially plugged tip. Clean. See Clean the Gun Daily, page 33. Worn/damaged tip or air cap holes. Clean or replace. Pattern pushed to one side; air cap gets dirty. Air cap holes plugged. Clean.
Troubleshooting Gun Operation Troubleshooting Problem Cause Solution Excessive spray fog. Atomizing air pressure too high. Close atomizing air valve part way, or decrease air pressure as low as possible; minimum 45 psi (0.32 MPa, 3.2 bar) needed at gun for full voltage. Fluid too thin. Increase viscosity. Atomizing air pressure too low. Open atomizing air valve more or increase gun air inlet pressure; use lowest air pressure necessary. Spray tip is too large. Use smaller tip.
Troubleshooting Electrical Troubleshooting Problem Cause Solution Poor wrap. ES On/Off switch is OFF (O). Turn ON (I). Gun air pressure too low (ES indicator is amber). Check air pressure to gun; minimum 45 psi (0.32 MPa, 3.2 bar) needed at gun for full voltage. Atomizing air pressure too high. Decrease. Fluid pressure too high. Decrease, or replace worn tip. Incorrect distance from gun to part. Should be 8-12 in. (200-300 mm). Poorly grounded parts. Resistance must be 100 ohms or less.
Troubleshooting Problem Cause Solution Voltage/current display stays red (smart guns only). Gun is too close to the part being sprayed. Gun should be 8–12 in. (200–300 mm) from the part. Dirty gun. See Clean the Gun Daily, page 33. ES or Hz indicator is amber. Air turbine speed is too low. Increase air pressure until indicator is green. To avoid over-atomization, use the atomizing air restrictor valve to reduce the atomizing air to the air cap. ES or Hz indicator is red.
