Overview

How the Electrostatic Air Spray

Gun Works

The automatic electrostatic air spray gun operates very

similar to a traditional air spray gun. The atomization

and fan air are emitted from the air cap. The atomization

air breaks up the fluid stream and controls the droplet

size. The fan air controls the shape and width of the

spray pattern. The fan and atomization air can be

adjusted independently.

Operating the Spray Function

Applying a minimum of 50 psi (0.35 MPa, 3.5 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 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 and external

charging probe. Atomized fluid particles become

charged as they pass by the external probe, and are

attracted to the grounded workpiece, evenly coating all

surfaces. The external charging allows the fluid supply

to remain grounded at all times, eliminating the need for

an isolation system.

The turbine air is exhausted into the shroud and out the

back of the manifold through the exhaust fitting (EXH).

The exhaust air helps keep contaminants out and helps

keep the gun clean.

Gun Features and Options

•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 the fluid and air lines

to the gun.

•Gun functions are activated from a separate control-

ler that sends the appropriate signal to the actuating

solenoids.

•The optional fiber optic readout system can be

installed to monitor the gun’s spraying voltage. A

fiber optic cable connected to the gun manifold car-

ries the signal from the gun to a remote display

module. Part No. 224117 Display Module displays

the gun’s spraying voltage and current. Bat-

tery-operated Display Module 189762 displays the

gun’s spraying voltage only.

Changing the kV Setting

For this external charge gun it is recommended that the

gun be left at full voltage, but if needed the voltage can

be reduced.

The gun’s full voltage setting is 60 kV. Three lower volt-

age settings are possible by actuating the KV1 and KV2

switches. Supply 50 psi (0.35 MPa, 3.5 bar) air pressure

to the KV1 and KV2 ports. Turn the air on or off as

shown in Table 1 to set the desired voltage.

NOTE: The solenoid valves used to activate the KV1

and KV2 switches must bleed the air out of the lines for

the switches to draw back to the higher voltage setting.

suit your particular needs, contact your Graco distribu-

tor.

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

Electrically interlock the gun air supply with the ventila-

tors to prevent gun operation without ventilating fans

operating. Check and follow all National, State, and

Local codes regarding air exhaust velocity require-

ments.

High velocity air exhaust will decrease the operating effi-

ciency of the electrostatic system. Air exhaust velocity of

100 ft/min (31 linear meters/minute) should be sufficient.

Connect the Charging Probe

1. Apply dielectric grease to the charging probe

socket. See FIG. 4.

2. Install the charging probe in the Connect/Discon-

nect position shown in FIG. 5.

3. Rotate the charging probe to spray position.

NOTE: For proper performance, do not operate electro-

statics if the charging probe is not in spray position.

Install the Air Line Accessories

1. Install a bleed-type air valve (L) on the main air line

(W) to shut off all air to the gun (H).

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 regulator (M) on each of the

air supply lines (B, C, D, E, X, Y) to control air pres-

sure to the gun.

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.

Install the Fluid Line

Accessories

1. Install a fluid filter and drain valve at the pump out-

let.

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

fluid pressure to the gun.

Spray

Position

Trapped air can cause the gun to spray

unexpectedly, which can result in serious injury,

including splashing fluid in the eyes or on the skin.

The solenoid 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.

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 drain valve

reduces the risk of serious injury, including splashing

in the eyes or on the skin.

Grounding

The following are minimum grounding requirements for

a basic electrostatic system. Your system may include

other equipment or objects which must be grounded.

Check your local electrical code for detailed grounding

instructions. Your system must be connected to a true

earth ground.

•Pump: ground the pump by connecting a ground

wire and clamp as described in your separate pump

instruction manual.

•Electrostatic Air Spray Gun: ground the gun by con-

necting the Graco Grounded Air Hose to the turbine

air inlet and connecting the air hose ground wire to a

true earth ground. See Check Electrical Ground-

ing, page 13.

•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 plastic.

•Object being sprayed: keep the workpiece hangers

clean and grounded at all times. Resistance must

not exceed 1 megohm.

•The floor of the spray area: must be electrically con-

ductive and grounded. Do not cover the floor with

cardboard or any non-conductive material which

would interrupt grounding continuity.

•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.

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. Follow the grounding instructions

below.

Installation

313227C 13

Check Electrical Grounding

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.

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 grey 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,

Check Fluid Resistivity

Graco Part No. 722886 Resistance Meter and 722860

Probe are available as accessories to check that the

resistivity of the fluid being sprayed meets the require-

ments of an electrostatic air spray system.

Follow the instructions included with the meter and

probe. If the material is above 1 megohm-cm, then a Pro

Xs Auto HC gun may be a better option. The Pro Xs WB

gun is intended to spray very conductive waterborne

materials and other materials less than 1 megohm-cm.

Check Fluid Viscosity

To check fluid viscosity you will need:

•a viscosity cup

•a stopwatch.

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. If the viscosity is too high or too low, contact the

material supplier. Adjust as necessary.

Install the Fabric Cover

1. Install a fabric cover (XX) over the front of the gun

and slide it back to cover the exposed tubing and

hoses at the back of the manifold. See FIG. 11.

2. Route the exhaust tube (YY) outside the cover. This

enables you to monitor the exhaust tube for the

presence of any paint or solvent. See Check for

Fluid Leakage on page 21. Strap down the exhaust

tube to prevent it from moving around.

Fire, Explosion, and Electric Shock Hazard

Check the fluid resistivity in a non-hazardous area

only. Resistance Meter 722886 and Probe 722860 are

not approved for use in a hazardous area.

Failure to follow this warning could cause fire,

explosion, or electric shock and result in serious injury

and property damage.

Operation

Pressure Relief Procedure

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. Turn off the main air supply by closing the

bleed-type master air valve on the main air supply

line. Leave the valve closed until you are ready to

spray again.

Operating Checklist

Check the following list daily, before starting to operate

the system, to help ensure you of safe, efficient opera-

tion.

The system pressure must be manually relieved to

prevent the system from starting or spraying

accidentally. To reduce the risk of an injury from

electric shock, accidental spray from the gun,

splashing fluid, or moving parts, follow the Pressure

Relief Procedure whenever you:

•are instructed to relieve the pressure

•stop spraying

•check or service any of the system equipment

•or install or clean the fluid nozzle.

All operators are properly trained to safely

operate an automatic electrostatic air spray

system as instructed in this manual.

All operators are trained in the Pressure

Relief Procedure on page 15.

The warning sign provided with the gun is

mounted in the spray area where it can be

easily 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 12.

The condition of the gun’s electrical compo-

nents has been checked as instructed in Elec-

trical Tests on page 22.

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 21.

Operation

16 313227C

Select a Fluid Nozzle and Air

Cap

The gun is supplied with Part No. 197266 Nozzle and

24A276 Air Cap. If you require a different size, refer to

Table 2 and instruction manual 309419, or consult with

your Graco distributor. See Replace Air Cap/Nozzle on

page 30.

NOTE: Due to the larger needle diameter, use a nozzle

one size larger than you would use with a standard PRO

Xs gun (i.e., 1.5 mm = 1.2 mm flow area).

* Glass-reinforced acetal construction.

Adjust the Spray Pattern

Follow the steps below to establish the correct fluid flow

and air flow. Do not turn on the turbine air (TA) yet.

1. Relieve pressure, page 15.

2. Loosen the air cap retaining ring, and rotate the air

cap for a vertical or horizontal spray pattern. See

FIG. 12. Tighten the retaining ring until the air cap is

held firmly in place; you should not be able to rotate

the air cap horns by hand.

3. Adjust the fluid flow with the fluid pressure regulator.

Refer to instruction manual 309419 to set the fluid

pressure for various fluid flows, according to the size

of the fluid nozzle being used.

4. Use the air pressure regulator on the atomization air

supply line (A1) to adjust the degree of atomization.

See FIG. 13. For example, for a fluid flow rate of 10

ounces per minute (0.3 liters per minute), a typical

atomization pressure would be 20-30 psi (1.4-2.1

bar, 0.14-0.21 MPa) at the gun manifold.

To reduce the risk of an injury, follow the Pressure

Relief Procedure procedure on page 15 before

removing or installing a fluid nozzle and/or air cap.

The fluid nozzle (4) must be in place when removing or

installing the jam nut and actuator arm.

1. Install the adjustment nut (30), actuator arm (29),

and jam nut (28) onto the piston rod (16b). Note that

the jam nut (28) has a slightly larger hex and a thin-

ner profile than the adjustment nut (30). See FIG. 26

on page 34.

2. Position the parts so there is a 0.125 in. (3 mm) gap

between the actuator arm (29) and the fluid packing

rod nut (E), which allows the atomizing air to actuate

before the fluid. See FIG. 28.

3. Tighten the adjustment nut (30) against the actuator

arm (29). Check that the 0.125 in. (3 mm) gap has

been maintained. In addition, there should be 3-4

mm of electrode needle travel when the gun is trig-

gered. Adjust the jam nut position to obtain these

dimensions.

on the date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by

Graco, Graco will, for a period of twelve months or two thousand hours of operation from the date of sale, repair or replace any

part of the equipment determined by Graco to be defective. However, any deficiency in the barrel, handle, trigger, hook, internal

operation from the date of sale. This warranty applies only when the equipment is installed, operated and maintained in

accordance with Graco's written recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused

by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering,

or substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the

incompatibility of Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper

for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts.

The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose

any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts,

labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT

NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco's sole obligation and buyer's sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no
