47 7

FIRE OR EXPLOSION HAZARD

To reduce the risk of fire, explosion, or electric shock, which may result from electrical discharge, it is essential that:

SAll parts of the electrostatic system are properly grounded.

SAll personnel in or close to the spray area are properly grounded.

SAll electrically conductive objects or devices in the spray area, including paint containers, wash cans and tools, are properly grounded.

When operating the electrostatic device, any ungrounded objects in the spray area (such as people, containers, tools, etc.) can become electrically charged. Arcing may occur if these objects then come in contact or close to ground. Arcing of sufficient energy levels can ignite the fluid being sprayed, fumes from solvents, dust particles, and other flammable substances. This can cause a fire or explosion and result in serious bodily injury and property damage.

Static electricity can also be generated by the flow of fluid through the pump, hose, gun, and nozzle, but it is dissipated through proper grounding as described in Grounding below.

If you experience any arcing or feel even a slight shock, STOP SPRAYING IMMEDIATELY. Check for proper grounding of the entire system. Be sure you have corrected the problem before starting to spray again.

Grounding

The following are minimum requirements for grounding a basic electrostatic system. Your system may include other equipment or objects which must also be grounded. Always check your local electrical code for detailed grounding instructions. Be sure your system is connected to a true earth ground.

1.Pump: ground by using a ground wire and clamp as described in your separate pump instruction manual.

2.Air compressors and hydraulic power supplies: ground according to the manufacturer's recommendations.

3.Electrostatic Spray Gun: obtain grounding through connection to a properly grounded air supply hose. Use only the Graco Electrically

Conductive Air Supply Hose; see ACCESSORIES section to order. Connect the air hose ground wire to a true earth ground.

4.Object being sprayed: keep the work piece hangers clean and grounded at all times. Contact points must be sharp points or knife edges.

5.All electrically conductive objects or devices in the spray area, including paint containers and wash cans, must be properly grounded.

6.All persons entering the spray area: shoes must have conductive soles, such as leather, or personal grounding straps must be worn. Rubber or plastic soles are not conductive.

7.The floor of the spray area must be electrically conductive and grounded. Do not cover the floor with cardboard or anynon-conductivematerial which would interrupt grounding continuity.

8.Flammable liquids in the spray area must be kept in approved, grounded containers. Do not store more than the quantity needed for one shift.

9.All solvent pails: use only grounded metal pails, which are conductive. Do not place the pail on anynon-conductivesurface, such as cardboard or paper, which would interrupt grounding continuity.

10.All air and fluid lines and electric cables must be properly grounded.

Flushing and Cleaning Safety

To reduce the risk of static sparking or splashing, always follow the Pressure Relief Procedure on page 4.

Be sure the turbine air (electrostatics) is OFF before flushing or cleaning any part of the spray system.

Use the lowest possible pressure to flush. Trigger the gun into a grounded metal waste container.

To flush or purge equipment, ALWAYS use solvents with a flash point equal to or greater than that of the fluid being sprayed.

To clean the exterior of the equipment, ALWAYS use solvents with a flash point of higher than 38_ C (100_ F).

ALWAYS remove all solvent from the system before reactivating the spray gun.

Use only non-sparkingtools to clean residue from the booth and hangers.

Ventilate the Spray Booth

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.

NEVER operate the spray gun unless the ventilating fans are operating.

Check and follow all National, State and Local codes regarding air exhaust velocity requirements. Check and follow all local safety and fire codes and OSHA standard 1910±107(b)(5)(i).

IMPORTANT

United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards±±particularly the General Standards, Part 1910.107 and any other appropriate regulations±±should be consulted in connection with the installation, operation, and maintenance of electrostatic spray painting equipment.

HOW THE ELECTROSTATIC AIR SPRAY GUN WORKS

The air hose supplies air to the spray gun. Part of the air operates the turbine and the rest of the air atomizes the fluid being sprayed. The turbine generates power, which is converted by the power cartridge, to supply high voltage current to the gun's ionizing electrode.

The pump supplies fluid to the hose and gun, where the fluid is electrostatically charged as it passes the electrode. The charged fluid is attracted to the grounded workpiece, wrapping around and evenly coating all surfaces.

6307-712

INSTALLATION

Mount the Gun

Mount the gun on a stationary support or on a reciprocating arm. The mounting rod must be properly grounded.

Mount the gun so the front of the gun is 254 to 300 mm (10 to 12 in.) from the work piece.

Connect the Air Line (Refer to the Typical Installation Drawing)

WARNING

To reduce the risk of electric shock or other serious bodily injury, the air supply hose must be electrically connected to a true earth ground. Use Only Graco Electrically Conductive Air Supply Hose. This hose, and the gun, have special threads which prevent using any other type of hose with the gun. See theACCESSORIES section to order the hose.

1.Install an air line filter (K) and an air and water separator (B) on the main air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece and can cause the gun to malfunction.

2.Install an air line lubricator (D) close to the pump air inlet.

3.Install a normally closed, 3-wayair solenoid (P) or manual valve on the turbine, cylinder and remote fan air supply lines.(The remote fan line is optional.)

4.Install a bleed-typeair regulator (E) on the pump, turbine, atomizing, cylinder, and remote fan(optional) air supply lines to control air pressure to the pump and gun.

5.Install a bleed-typeair shutoff valve (A) on the main air line, the pump line, and each gun air supply line to shut off air to the pump and gun.

WARNING

The bleed±type air shutoff valve(A) is required in your system to relieve air trapped between this valve and the pump after the air regulator is closed. Trapped air can cause the pump to cycle unexpectedly, which could result in serious bodily injury, including splashing in the eyes or on the skin and injury from moving parts.

6.Connect the cylinder air line to the gun's cylinder air inlet (marked CYL).

7.Connect the atomizing air line to the gun's atomizing air inlet (marked ATOM).

8.Connect the turbine air supply line to the gun's air inlet (marked ES).The gun air inlet fitting has a left hand thread. Connect the air supply hose ground wire to a true earth ground.

9.A remote fan air adapter is available to control the fan air at the control booth. See Installing the Optional Remote Fan Air Adapter, on page 8.

Connect the Fluid Line (Refer to the Typical Installation Drawing)

1.Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent which is compatible with the fluid to be sprayed.

2.Install a fluid regulator (L) on the fluid line to control fluid pressure to the gun.

3.Install a fluid filter (G) and drain valve (H) at the pump outlet.

WARNING

The fluid drain valve (H) is required in your system to assist in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may not be sufficient. Install a drain valve close to pump's fluid outlet. The drain valve reduces the risk of property damage or serious bodily injury, including splashing in the eyes or on skin and contamination from hazardous fluids.

4. Connect the fluid line to the gun fluid inlet.

CAUTION

Do not use metal fittings at the gun barrel. For circulation systems, use plastic fittings.

INSTALLATION

9.Be sure all conductive objects within 6 m (20 ft) of the gun are electrically grounded and the floor of the spray area is electrically conductive and grounded.

Filter the Fluid

Filter the fluid to remove coarse particles and sediment which could clog the spray nozzle.

Spraying Operation

This gun has a built-inlead and lag operation. The gun begins emitting air before the fluid is discharged. When you release the trigger, the fluid stops before the air flow stops. This helps prevent fluidbuild-upon the air cap.

Adjust the system's control device, if it is automatic, so the gun starts spraying just before meeting the work piece, and stops as soon as the work piece has passed.

When spraying, the ES indicator lights (BB) should glow, indicating the electrostatic charge. See Fig 4.

Selecting a Fluid Nozzle and Air Cap

WARNING

To reduce the risk of serious bodily injury, including splashing in the eyes or on the skin or electric shock, always follow the Pressure Relief Procedure, above, before installing, or removing the fluid nozzle/air cap assembly.

This gun is supplied with fluid nozzle 181±299 and air cap 180±739. See Instruction Manual 307±803 for air cap consumption and fluid nozzle flow rate information.

The fluid output and pattern shape depends on the fluid nozzle size, fluid viscosity, and fluid pressure. If your application requires a different nozzle and air cap combination, use manual 307±803 to select the appropriate fluid nozzle and air cap.

To install a different fluid nozzle and air cap, see To Clean or Change Air Cap and Fluid Nozzle, page 12.

OPERATION

Adjust the Spray Pattern

Follow the steps below to establish the correct fluid flow and air flow. DO NOT turn the turbine air on yet.

1.Adjust the fluid flow for the appropriate flow rate by using the fluid pressure regulator installed in the fluid line. Check the fluid nozzle chart in manual 307±803 for the appropriate flow rate for the air cap. Start with the lowest rate shown and increase it until you get the desired flow rate.

2.For fine adjustment of how much fluid is sprayed, tighten or loosen the trigger adjusting nut (24). See Fig 4. Turn the nut out to reduce the amount of fluid sprayed or turn itin to increase the amount.

3.Close the fan adjusting knob (56) by turning it fully clockwise.

4.Use an air pressure regulator to adjust the degree of atomization. Always use the lowest air pressure possible for the most efficiency.

5.Use the fan adjusting knob to change the shape of the spray pattern. Turn the knobcounterclockwise for a wide pattern andclockwise for a solid, round pattern. When increasing to a wide, flat pattern, it may be necessary to increase the supply of fluid to the gun to maintain the same amount of coverage over a large area.

6.First, complete all the checks under the Operating Checklist on page 9. Then turn the turbine air on. When spraying, theES indicator light (51) should glow, indicating the electrostatic charge.

NOTE: Provide a 3.1 bar (45 psi) clean, dry, regulated air supply to the gun to ensure full voltage from the power supply. The gun may be operated at lower turbine air pressure, but may lose some electrostatic effect. Do not operate the turbine at an air pressure greater than 3.1 bar (45 psi) as there is no benefit and turbine life will be reduced.

NOTE: A remote fan air adapter is available to control the fan air at the control booth. See

ACCESSORIES.

ELECTRICAL TESTS

The performance of the spray gun is directly affected by the condition of the electrical components contained inside the gun. The electrical tests below can be used to determine the condition of the power supply (5) and the resistor stud (17) as well as the continuity of the electrical path between the components.

Use megohmmeter 218±979 (see ACCESSORIES) and an applied voltage of 500 volts to complete these electrical tests. Connect the leads as shown.

WARNING

To reduce the risk of sparking, which could cause fire or explosion and result in serious bodily injury, DO NOT use the megohmmeter in the hazardous area. Remove the gun from the hazardous area before testing it.

Test Gun Resistance

NOTE: Check the resistance with the gun triggered and untriggered.

Measure the resistance between the end of the electrode (14) and the gun air inlet adapter (86). See Fig 7. The resistance should be between 115 to 152 megohms. If the resistance is outside the specified range, go to the next test. If the resistance is correct, refer to the Electrical Troubleshooting Chart on page 15 for other possible causes of poor performance.

Test Power Supply Resistance

Remove the power cartridge (2) from the gun body (1). See Power Cartridge Replacement.

Remove the turbine alternator (2a) from the power supply (5). See Turbine Alternator Removal.

Measure the resistance from the center prong (EE) in the power supply to the contact spring (5c) on the other end of the power supply. See Fig 8.

The resistance should be 95 to 122 megohms. If the resistance is outside the specified range, the power supply is defective and must be replaced. If the resistance of the power supply is correct, proceed to the next test.

If you still have problems, refer to the Electrical Troubleshooting Chart for other possible causes of poor performance, or contact the nearest authorized service agency.

ELECTRICAL TESTS

Test Resistor Stud Resistance

Insert a conductive rod (FF) into the gun barrel (removed for the power supply test) and against the metal contact (GG) in the front of the barrel. See Fig 9.

Measure the resistance between the conductive rod (FF) and the gun electrode (14). The resistance should be 20 to 30 megohms. If the resistance is correct, refer to the

Electrical Troubleshooting Chart for other possible causes of poor performance, or contact the nearest authorized service agency.

If the resistance is outside the specified range, remove the electrode (14). See Electrode Replacement. Measure the resistance between the conductive rod (FF) and the resistor in the inside diameter of resistor stud (17).

The resistance should be 20 to 30 megohms. If the resistance is correct, the electrode wire is defective and must be replaced. See Electrode Replacement. If the resistance is outside the specified range, the resistor is defective and the resistor stud (17) must be replaced. SeeResistor Stud Replacement.

If you still have problems, refer to the Electrical Troubleshooting Chart for other possible causes of poor performance, or contact the nearest authorized service agency.
