Introduction

Introduction

How the Electrostatic AA Spray

Gun Works

This is not an air spray gun. To help prevent serious injury from pressurized fluid, such as skin injection, and splashing fluid, read and follow the Skin Injection

Hazard Warnings on page 5.

The electrostatic air-assisted spray gun combines air less and air spraying concepts. The spray tip shapes the fluid into a fan pattern, as does a conventional air less spray tip. Air from the air cap further atomizes the fluid and completes the atomization of the fluid tails to produce a uniform pattern.

The high working fluid pressure of this gun provides the power needed to atomize higher solid materials.

Operating the Spray Function

Applying a minimum of 60 psi (0.42 MPa, 4.2 bar) air pressure to the gun manifold’s cylinder air fitting (CYL) will retract the gun piston, which opens the air valves and a short time later opens the fluid needle. This pro vides the proper air lead and lag when triggering the gun. A spring returns the piston when the cylinder air is shut off.

Operating the Electrostatics

To operate the electrostatics, apply air pressure to the gun manifold’s turbine air fitting (TA) through a Graco

Grounded Turbine Air Hose. The air enters the manifold and is directed to the inlet of the power supply turbine.

The air spins the turbine, which then provides electrical power to the internal high voltage power supply. The fluid is charged by the spray gun electrode. The charged fluid is attracted to the nearest grounded object, wrapping around and evenly coating all sur faces.

Gun Features and Options

• The gun's full voltage setting is 85kV.

• The gun is designed for use with a reciprocator, and can be mounted directly on a 1/2 in. (13 mm) rod. With additional brackets, the gun can be mounted for robotic applications.

• The gun’s quick-disconnect design enables its removal without disconnecting air lines to the gun.

• Gun functions are activated from a separate con troller that sends the appropriate signal to the actu ating solenoids.

Smart Gun Features

Smart gun models with the Pro Xp Auto Control Module have the ability to:

• Display the spraying voltage and current

• Change the gun voltage setting

• Display the gun turbine speed

• Store spray profiles

• Communicate equipment faults to a PLC

• Display and set maintenance totalizers

• Use a PLC to select a spray profile

See the Pro Xp Auto Control Module manual 332989 for more information.

Installation

Installation

Install the System

Installing and servicing this equipment requires access to parts which may cause electric shock or other seri ous injury if work is not performed properly.

• Do not install or service this equipment unless you are trained and qualified.

• Be sure your installation complies with local, state, and national codes for the installation of electrical apparatus in a Class I, Div. I, hazardous location or a Group II, Zone I explosive atmosphere location.

• Comply with all local codes and regulations.

Warning Signs

Mount warning signs in the spray area where they can easily be seen and read by all operators. An English

Warning Sign is provided with the gun.

Ventilate the Spray Booth

Do not operate the gun unless ventilating air flow is above the minimum required value. Provide fresh air ventilation to avoid the buildup of flammable or toxic vapors when spraying, flushing, or cleaning the gun.

Interlock the gun air and fluid supply to prevent oper ation unless ventilating air flow is above the minimum required value.

The spray booth must have a ventilation system.

Electrically interlock the gun turbine air supply (B) with the ventilators to prevent gun operation any time that the ventilation air flow falls below minimum values.

Check and follow all local codes and regulations regarding air exhaust velocity requirements. Verify the operation of the interlock at least once a year.

NOTE: The minimum allowable air exhaust velocity is

60 feet/minute (19 linear meters/minute). High velocity air exhaust will decrease the operating efficiency of the electrostatic system.

Install the Air Line Accessories

See F IGURE 3.

1. Install a bleed-type master air valve (L) on the main air line (W) to shut off all air to the gun.

2. Install an air line filter/water separator on the gun air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your fin ished workpiece and can cause the gun to malfunc tion.

3. Install a bleed-type air pressure regulator (M) on each of the air supply lines (B, C, D, E) to control air pressure to the gun.

Trapped air can cause the gun to spray unexpect edly, which can result in serious injury, including splashing fluid in the eyes or on the skin. The sole noid valves (K) must have a quick exhaust port so trapped air will be relieved between the valve and gun when the solenoids are shut off.

4. Install a solenoid valve (K) on the cylinder air line (E) to actuate the gun. The solenoid valve must have a quick exhaust port.

5. Install a solenoid valve (K) to actuate the turbine.

Install Fluid Line Accessories

1. Install a fluid filter and drain valve at the pump out let. Filtering the fluid will help remove coarse parti cles and sediment that could clog the spray tip. The fluid drain valve 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 the pump's fluid outlet.

The gun includes an inline fluid filter for additional filtra tion.

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

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode.

Improper grounding can cause electric shock.

Ground all equipment, personnel, objects being sprayed, and conductive objects in or close to the spray area. The resistance must not exceed 1 meg ohm. Grounding provides an escape wire for the elec tric current.

When operating the electrostatic gun, any ungrounded objects (such as people, containers, and tools) in the spray location can become electrically charged.

The following are minimum grounding requirements for a basic electrostatic system. Your system may include other equipment or objects which must be grounded.

Your system must be connected to a true earth ground.

Check ground connections daily. Check your local electrical codes and regulations for detailed grounding instructions.

• Pump: ground the pump by connecting a ground wire and clamp as described in your separate pump instruction manual.

• Electrostatic Air Assisted Spray Gun: ground the gun by connecting the Graco Grounded Turbine Air

Hose to the turbine air inlet and connecting the air hose ground wire to a true earth ground. See

Check Gun Electrical Grounding, page 15.

• Air compressors and hydraulic power supplies: ground the equipment according to the manufac turer's recommendations.

• All air and fluid lines must be properly grounded.

• All electrical cables must be properly grounded.

• All persons entering the spray area: shoes must have conductive soles, such as leather, or personal grounding straps must be worn. Do not wear shoes with non-conductive soles such as rubber or plas tic.

• Object being sprayed: keep the workpiece hang ers clean and grounded at all times. Resistance must not exceed 1 megohm.

• 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.

333011L

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

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

• Fluid and waste containers: ground all fluid and waste containers in the spray area. Do not use pail liners unless they are conductive and grounded.

When flushing the spray gun, the container used to catch the excess fluid must be electrically conduc tive and grounded.

• All solvent pails: use only approved, grounded metal containers, which are conductive. Do not use plastic containers. Use only non-flammable sol vents. Do not store more than the quantity needed for one shift.

Check Gun Electrical Grounding

Megohmmeter Part No. 241079 (AA-see F IGURE 8) is

not approved for use in a hazardous location. To reduce the risk of sparking, do not use the megohm meter to check electrical grounding unless:

• The gun has been removed from the hazardous location;

• Or all spraying devices in the hazardous location are turned off, ventilation fans in the hazardous location are operating, and there are no flammable vapors in the area (such as open solvent containers or fumes from spraying).

Failure to follow this warning could cause fire, explo sion, and electric shock and result in serious injury and property damage.

Graco Part No. 241079 Megohmmeter is available as an accessory to check that the gun is properly grounded.

1. Have a qualified electrician check the electrical grounding continuity of the spray gun and turbine air hose.

2. Make sure the turbine air hose (B) is connected and the hose ground wire is connected to a true earth ground (N).

3. Turn off the air and fluid supply to the gun. The fluid hose must not have any fluid in it.

4. Measure the resistance between the turbine air inlet fitting (TA) and a true earth ground (N). a. If using a black or gray turbine air hose, use a

Megohmmeter to measure the resistance. Use an applied voltage of 500 minimum to 1000 volts maximum. The resistance should not exceed 1 megohm.

b. If using a red turbine air hose, use an ohmmeter to measure the resistance. The resistance should not exceed 100 ohms.

5. If the resistance is greater than the maximum read ing specified above for your hose, check the tight ness of the ground connections and be sure the turbine air hose ground wire is connected to a true earth ground. If the resistance is still too high, replace the turbine air hose.

Check Fluid Resistivity

To reduce the risk of fire, explosion, or electric shock, check the fluid resistivity in a non-hazardous location only. Resistance Meter 722886 and Probe 722860 are not approved for use in a hazardous location.

Check that the resistivity of the fluid being sprayed meets the requirements for an electrostatic air spray system. Graco Part No. 722886 Resistance Meter and

722860 Probe are available as accessories. Follow the instructions included with the meter and probe.

Fluid resistivity readings of at least 25 megohms-cm generally provide the best electrostatic results and are recommended.

Check Fluid Viscosity

A viscosity cup and stopwatch are needed to check fluid viscosity.

1. Completely submerge the viscosity cup in the fluid.

Lift the cup out quickly, starting the stopwatch as soon as the cup is completely removed.

2. Watch the stream of fluid coming from the bottom of the cup. As soon as there is a break in the stream, shut off the stopwatch.

3. Record the fluid type, elapsed time, and size of the viscosity cup.

4. Compare to the chart supplied by viscosity cup manufacturer to determine your fluid viscosity.

5. If the viscosity is too high or too low, contact the material supplier. Adjust as necessary.

Pressure Relief Procedure

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as splashing, follow the Pres sure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equip ment.

1. Turn off all the air to the spray gun except the cylin der air, which triggers the gun. If an air pilot fluid regulator is used in the system, the air pressure is needed at the regulator air inlet.

2. Turn off the fluid supply to the gun.

3. Trigger the gun into a grounded metal waste con tainer to relieve the fluid pressure.

4. If an air pilot fluid regulator is used, turn off the air pressure at the regulator air inlet.

5. Relieve fluid pressure in the fluid supply equipment as instructed in its instruction manual.

6. Open the pump drain valve and all other drain valves in the system, having a waste container ready to catch the drainage. Triggering the gun to relieve pressure may not be sufficient. Leave the drain valve open until you are ready to spray again

7. Close the bleed-type master air valve on the main air supply line to shut off the air. Leave the valve closed until you are ready to spray again.

8. If you suspect that the spray tip or hose is still clogged or that pressure is not fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose obstruction.

Startup

Check the following list daily, before starting to operate the system, to help ensure you of safe, efficient opera tion.

All operators are properly trained to safely operate an automatic electrostatic air-assisted spray system as instructed in this manual.

All operators are trained in the Pressure Relief

Procedure on page 18.

The warning sign provided with the gun is mounted in the spray area where it can be eas ily seen and read by all operators.

The system is thoroughly grounded and the operator and all persons entering the spray

area are properly grounded. See Grounding on page 15.

The condition of the gun’s electrical compo nents has been checked as instructed in

Elec trical Tests on page 26.

Ventilation fans are operating properly.

Workpiece hangers are clean and grounded.

All debris, including flammable fluids and rags, is removed from the spray area.

All flammable fluids in the spray booth are in approved, grounded containers.

All conductive objects in the spray area are electrically grounded and the floor of the spray area is electrically conductive and grounded.

The manifold exhaust tubes have been checked for the presence of any fluid as

instructed in Check for Fluid Leakage on page 25.

Select a Spray Tip

The fluid output and pattern width depend on the size of the spray tip, the fluid viscosity, and the fluid pres sure. Use the

Atomization fluid pressure will vary based on the vis cosity of the fluid, flow rate desired, and other system characteristics.

1. Turn off the turbine air (TA), atomization air (A1), and fan air (A2).

2. Start the pump. Set the fluid regulator to 400 psi

(2.8 MPa, 28 bar).

3. With the turbine air (TA), atomization air (A1), and fan air (A2) turned off, spray a test pattern, holding the gun 12 in. (305 mm) from the surface. Examine the particle size. Do not be concerned about the

presence of tails; they will be removed in step 6.

4. Increase the fluid pressure in small increments.

Spray another pattern and compare the particle size. Smaller particle size indicates improved atom ization.

WLD

F IG . 11. Install Air Cap Assembly

To reduce the risk of fire, explosion, or electric shock, never operate the gun with a damaged electrode.

To reduce the risk of injury, never exceed the maxi mum working pressure on the lowest rated system component. Maximum working pressure of this equipment is 3000 psi (21 MPa, 210 bar) .

5. Continue to increase the fluid pressure and spray test patterns. Do not exceed 3000 psi (21 MPa, 210 bar) fluid pressure. When the particle size remains constant, the fluid is being atomized at the lowest possible fluid pressure.

For improved atomization at lower fluid flow rates, change to a smaller tip orifice size.

6. Turn on the atomization air (A1) and adjust the air pressure until the tails disappear.

See Spray Pattern Troubleshooting on page 28 to

correct spray pattern problems.

2. Check the turbine speed of the gun by checking the indicator light on the standard gun body or for the smart gun check the actual turbine speed on the

Pro Xp Auto Control Module. See the following table. Adjust the air pressure as necessary to keep the indicator light green or the values within

400-750 Hz.

Smart models display values, not color indicator lights.

Table 2: Indicator Colors/Values

Description Indicator

When spraying, the indicator should remain green, indicating sufficient air pressure to the turbine.

If the indicator changes to amber after 1 second, the air pressure is too low. Increase air pressure until the indicator is green.

If the indicator changes to red after 1 second, the air pressure is too high. Decrease air pres sure until the indicator is green. Excessive tur bine speed can shorten the bearing life and will not increase the voltage output.

Check the voltage output of the gun using a high volt age probe and meter or by reading the Pro Xp Auto

Control Module.

The gun’s normal high voltage reading is 60-70 kV. If a ball end high voltage measurement probe is used, the gun voltage will rise to about 85 kV. This will happen with all resistive electrostatic guns.

See Electrical Troubleshooting on page 31 to correct

voltage problems.

Air Flow

Air Flow

The gun requires 6 scfm (170 l/min) of turbine air flow (see

Technical Specifications ). The following graph shows

additional air consumption. For example, at 30 psi inlet air pressure, the gun uses about 4 scfm (113 l/min) of atom izing air. Add this amount to the turbine air for a total of 10 scfm (280 l/min) air consumption. Typically, AA guns with correct tip selection will not need additional fan air.
