Overview
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 provides 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
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 carries the signal from the gun to a remote display
module. Part No. 224117 Display Module displays
the gun’s spraying voltage and current. Battery-operated Display Module 189762 displays the
gun’s spraying voltage only.
Changing the kV Setting
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.
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 voltage 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.

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
Provide fresh air ventilation to avoid the buildup of
flammable or toxic vapors when spraying, flushing, or
cleaning the gun. Do not operate the gun unless
ventilation fans are operating.
Electrically interlock the gun air supply with the ventilators to prevent gun operation without ventilating fans
operating. Check and follow all National, State, and
Local codes regarding air exhaust velocity requirements.
High velocity air exhaust will decrease the operating efficiency of the electrostatic system. Air exhaust velocity of
100 ft/min (31 linear meters/minute) should be sufficient.

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 finished workpiece and can cause the gun to malfunction.
3. Install a bleed-type air regulator (M) on each of the
air supply lines (B, C, D, E, X, Y) to control air pressure 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.
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.

FIG. 5. Charging Probe Positions
3. Rotate the charging probe to spray position.
NOTICE
The external charging probe rotates easily. Do not
press too hard when rotating it or it could be damaged.
NOTE: For proper performance, do not operate electrostatics if the charging probe is not in spray position.
Install the Fluid Line Accessories
1. Install a fluid filter and drain valve at the pump outlet.
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.
2. Install a fluid regulator on the fluid line to control
fluid pressure to the gun.

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. Follow the grounding instructions
below.
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 manufacturer'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.

Check Fluid Resistivity
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.
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 requirements 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 F
IG. 11.

Pressure Relief Procedure
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.
1. Turn off all the air to the spray gun except the cylinder 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.
Operating Checklist
Check the following list daily, before starting to operate
the system, to help ensure you of safe, efficient operation.
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 components has been checked as instructed in Elec-
trical Tests on page 22.
Ventilation fans are operating properly.
2. Turn off the fluid supply to the gun.
3. Trigger the gun into a grounded metal waste container 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.
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.

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.
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.
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).

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 thinner profile than the adjustment nut (30). See F
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 F
IG. 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 triggered. Adjust the jam nut position to obtain these
dimensions.
