Applicators
Fluid Lines for Electrostatic Waterborne
Type Applicators
The fluid between the applicator and fluid supply will
be charged. To reduce the risk of electric shock, use
only Graco-supplied waterborne fluid hoses. See
also Step 9. Ground the Equipment, page 35.
Fluid lines may contain high-voltage fluid. Sparking
due to a hose leak could cause fire, explosion, or electrical shock. To reduce the risk of sparking:
• Connect all fluid lines into the grounded quick disconnect robot base.
• Use only genuine Graco coiled fluid tubes.
See Accessories, page 85, for a list of available waterborne hoses.
All three solventborne fluid lines are connected through
the robot into the robot base. The fluid then flows
through coiled fluid tubes and into the main housing.
Connect the solvent supply line to port S on the robot
base. The solvent then flows through a coiled fluid tube
and into the main housing. This port is 6 mm (1/4 in.).
a. Connect the paint supply line to port P.
b. Connect the solvent supply line to port S. This
port is 6 mm (1/4 in.).
c.
If needed, connect the fluid dump line to port D.
If not needed, plug kit (25C288) is available to
plug the dump passage in the applicator.
The paint and dump line hoses pass through the robot
base manifold (38) and make a fluid seal inside the hose
housing (85). Install the fluid lines in the robot base
according to the following directions.
1. Blow out the paint supply hose and the fluid dump
hose (if used) with air and flush with water before
connecting.
The paint and dump line ports are 8 mm (5/16 in.). Refer
to the Fluid Flow Rate Charts, page 98, to help determine the best tubing for your application.
To reduce the risk of electric shock, install hoses to
the correct height and tighten strain relief fittings
securely. Improper installation height or improperly
tightened strain relief fittings can cause fluid leakage.
2. Pass the paint supply line through the strain relief fitting (86) marked P on the robot base. Pass the
dump line through strain relief fitting D on the robot
base. Position the end of each hose 7.625 in.
(19.4 cm) above the manifold surface, as shown.
Make sure the ferrule (87) is in place and properly
oriented on the outer jacket of the hose, then tighten
the strain relief nut (88) to secure each hose in
place. Pull on the hoses to made sure they are
firmly held by the strain relief fitting.

Installation
Power Supply Cable
To avoid potential arcing which could ignite flammable
fumes, the power to the Electrostatic Controller must
be turned off before disconnecting any cable connection.
Use a tool to tighten cable connections securely.
Connect the 4-pin end of the power supply cable to connector R on the applicator.
NOTE: An accessory 6 ft. extension power cable part
number 19B884 can be installed at the applicator. The
short cable is quicker to replace in demanding applications.
Fiber Optic Cable (for Optional Speed Controller)
The applicator is equipped with a magnetic pickup sensor assembly that provides a signal used by the Speed
Controller. Connect a fiber optic cable to port F1 on the
manifold, so that it contacts the fiber optic extension
cable (64). The amount of fiber extending past the nut
should be 1.48 in. (37.6 mm). See Accessories, page
85, for available cables.
NOTICE
To avoid equipment damage, route all hoses and
cables away from sharp edges. Avoid sharp bends
and excessive strain on hoses or cables.
Connect a Ground Wire
Connect a ground wire to the ground screw at the robot
base. The applicator should also be grounded through
its connection to the grounded robot.

Step 2. Mount the Rotary
Applicator
NOTE: Be sure each tube, line, and cable is labeled.
1. With all lines and cables connected, use appropriate
screws to connect the spacer (43) securely to the
robot arm or adapter plate.
To reduce the risk of fire and explosion, all mounting
hardware must be non-conductive or be properly
grounded. Keep all grounded mounting hardware at
least 10 in. (25.4 cm) away from the charged components.
See Dimensions, page 90.
If required, attach an adapter plate to the robot arm
before connecting fluid and air lines. See Accessories,
page 85, for a list of adapter plates.
2. Use screws (44) to connect the robot base (38) to
the spacer (43).
3. Waterborne applications: Apply dielectric grease
to the fluid tubes before connecting the applicator.
4. Align the applicator connections with the robot base
and push the connections together. Slide the quick

Distance to Workpiece
To reduce the risk of fire and explosion, maintain a
Safe Distance of at least 6 in. (15.2 cm) between the
applicator and the workpiece at all times.
Position the cup a minimum of 6 in. (15.2 cm) from the
closest approach point of the workpiece. Take into
account potential rotation or swaying of the part. The arc
detection circuitry of the Electrostatic Controller helps
minimize the risk of an arc should a workpiece approach
too close to the charged cup. In addition, the Safe Distance of 6 in. (15.2 cm) must be maintained at all times.
A typical spraying distance is 9-14 in. (23-36 cm).
To reduce the risk of fire and explosion, the spray
area must remain free of rusted steel. Frictional contact between aluminum components and rusted steel
must be avoided.
ProBell System Logic Controller
The rotary applicator system can be controlled with a
System Logic Controller or with an existing PLC. A
System Logic Controller is required if your system
includes a ProBell Speed Controller or a ProBell Air
Controller. Mount the System Logic Controller in the
non-hazardous area. See manual 3A3955 for
installation instructions.
ProBell Speed Controller (Optional)
Mount the Speed Controller in the non-hazardous area,
as close to the applicator as possible to minimize pressure loss in the air lines. See manual 3A3953 for installation instructions.
ProBell Air Controller (Optional)
Graco offers two Air Controller options: Electronic and
Manual. Mount the Air Controller in the non-hazardous
area, as close to the applicator as possible to minimize
pressure loss in the air lines. See manual 3A3954 for
installation instructions and to see features of each air
controller.
Air Filters
Step 3. Mount Controllers and
Accessories
The following components are available to create a complete ProBell Rotary Applicator System. The ProBell
controllers have been designed and optimized for use
with the ProBell Rotary Applicator. Your system may use
all Graco components, or a combination of Graco equipment and other controls.
NOTICE
Air that is not filtered to specification can clog bearing
air passages and cause bearing failure. The warranty
does not cover a turbine damaged by contaminated
air.
Three air filtration stages are required to prevent contamination of the paint finish and to prevent damage to
the air bearing. Refer to Table 1 for the specifications of
each filter. Use only these recommended filters, or filters
that meet the same specifications. See manual 309919
for filter details, installation, and pipe size recommendations.
To reduce the risk of fire and explosion, do not install
equipment approved only for a non-hazardous
location in a hazardous location.
•
The temperature of the air as it enters the Pre-Filter
must be close to ambient.
ProBell Electrostatic Controller (Required)
•
Air must be dehydrated to a dew point of 10°F
(-12°C).
Mount the Electrostatic Controller in the non-hazardous
area. See ProBell Electrostatic Controller manual
3A3657 for installation instructions.

Filters must remove 99% of all aerosols.
•
Filters must remove particles of 0.5 micron and
larger. Graco filter 234403 removes particles down
to 0.01 microns.
•
Standard piping may be used only up to the pre-filters. All piping after the pre-filters should be brass,
stainless steel, or plastic hose.
•
Do not use any type of thread sealant or PTFE tape
downstream of the bearing air filter. Small particles
may loosen and plug the air holes in the turbine air
bearings.

Air Heaters
Air heaters may be needed in some applications. If the
surface temperature of the applicator falls below the dew
point of the paint booth, condensation may form on the
inside or outside of the applicator. This condensation is
caused by supply air that is too cool, or by the cooling of
the shaping and turbine airs as they exit the applicator.
A heater may be required to ensure that the temperature
of the turbine exhaust air is above the dew point of the
spray booth. Install heaters into the air supply lines (turbine, shaping airs).
Set the heater as low as possible to maintain the applicator surface temperatures above the dew point in the
booth.
NOTE: The maximum air temperature at the cup must
not exceed 120°F (49°C).

Installation
Step 4. Connect the Fluid Supply
Connect fluid lines at the applicator first. See Step 1.
Connect All Lines at the Applicator, page 16.
An air purge is recommended for use with conductive
solvents to improve electrostatic performance
NOTE: Not purging the lines of conductive solvents may
cause low electrostatic voltage or system errors.
Solventborne and Non-Electrostatic
Systems
a. Paint Hose: The fluid hose connected to port P on
the applicator must be connected to a regulated, filtered paint supply, such as a circulation system or a
supply pump. This hose also must be connected to
a regulated solvent supply to flush the system and
an air supply to empty the lines. This illustration
shows a common way to make these connections.
Electrostatic Waterborne Systems
The fluid between the applicator and the fluid supply
will be charged. To reduce the risk of electric shock,
follow hose requirements and instructions carefully.
b. Dump Hose (optional): The fluid hose connected
to port D on the applicator must go to a grounded
waste container.
a. General Requirements: Waterborne isolation systems must meet these requirements:
• Fluid Supply
- All conductive components of the fluid supply
(pump, filter, regulator, container, etc.) that
are charged to high voltage must be bonded
together.
- If non-conductive containers are used, a
conductive element bonded to the fluid supply
must be in contact with the fluid.
• Fluid Hose
- Use only approved Graco Waterborne fluid
hoses.
c. Solvent Hose: The fluid hose connected to port S
on the applicator must be connected to a regulated
solvent supply that will be used to wash the cup.
This line must also be connected to a regulated air
supply to purge the cup wash passages with air.
24
- Unshielded waterborne fluid hoses must be
routed such that a minimum distance of 0.25
cm/kV is maintained between the hose and
grounded surfaces.
- The conductive layer of shielded hoses must
be grounded at the isolation system.
334626K
Installation
• Enclosure
- All components of the isolated fluid supply
system must be housed in a protective
enclosure to prevent contact with the charged
components during operation.
- Access to the enclosure must be interlocked
with the high voltage supply to shut off and
discharge the high voltage before any live
parts can be reached.
c. Dump Hose (optional): The most common system
design for the dump line (connected to port D) is to
connect a waterborne fluid hose to a grounded
waste container. Flush and purge the dump line with
air before turning on the electrostatics.
A second dump option is to place the waste container in
the voltage isolation enclosure. Connect a Graco Waterborne Fluid Hose between the voltage isolation system
fluid outlet and the applicator dump port (D).
b. Paint Hose: The fluid hose connected to port P on
the applicator must be connected to a regulated, filtered paint supply. This hose also must be connected to a regulated solvent supply to flush the
system. Connect an air supply to empty the lines, if
needed. The illustration below shows a common
way to make these connections.
334626K
d. Solvent Hose: The fluid hose connected to port S
on the applicator must be connected to a grounded,
regulated solvent supply that will be used to wash
the cup. This line must also be connected to a regulated air supply to purge the cup wash passages
with air. An air purge is required for very conductive
waterborne fluids.
NOTE: Not purging the lines will cause low electrostatic
voltage or system errors.
An isolated solvent kit 25N020 is also available for
waterborne systems that have the solvent supply inside
the isolation system.

• An unshielded hose consists of a PTFE tube (Y)
with an outer covering (X).
If a hose failure occurs where high voltage arcs
through the inner tube, voltage will be
discharged to ground through the conductive
hose layer. When properly installed, the
conductive hose layer is grounded through its
connection to the grounded enclosure.
The fluid supply end of the hose has been
stripped at the factory for connection to a
WB100 Isolation System, as shown below. If
desired, the hose can be changed on this end,
but the conductive layer (W) must be no closer
than 8 in. (20.3 cm) to the end of the hose or
any other high-voltage component. See Ref. U
in the illustration.
NOTICE
Be careful not to cut into the inner tube (Y)
of the hose when stripping the hose. Nicks
or cuts in the PTFE tube will cause premature hose failure.
NOTE: Blow out the fluid supply hose and
circulation hose (if used) with air and flush with
water before connecting.
Connect one end of the hose to the applicator.
Connect the other end to a fluid supply inside an
isolation enclosure.
Route unshielded hoses away from grounded
objects. Maintain a distance of 0.25cm/kV
between the hose and grounded objects.
26
To reduce the risk of electric shock, the areas of the
Graco waterborne fluid hose that are accessible to
personnel during normal operation must be
covered by the outer hose jacket (X). The portion
of the inner PTFE tube (Y) not covered by the
outer jacket (X) must be inside the isolation
enclosure (T).The conductive hose layer (W) must
be grounded at the isolation enclosure (T).
334626K
Installation
Step 5. Connect the Air Lines
• Connect the fluid hose(s) as follows:
1. Pass the Graco waterborne fluid hose
through a strain relief fitting at the wall of the
isolated enclosure and connect the inner
tube (Y) to the fluid supply outlet. Tighten the
strain relief fitting (Z). For a shielded hose,
the conductive layer of the hose (W) must be
grounded to the isolation system ground
(strain relief fittings must grab onto the outer
jacket or conductive layer of the fluid hose)
Y
Connect all air lines to the applicator first (See Step 1.
Connect All Lines at the Applicator, page 16). The air
supply for each line can be regulated and actuated
using the ProBell Speed Controller and/or one of the
ProBell Air Controllers (see Table 2: Air Line Connections Availability by Controller, page 31). Spray parameters can be adjusted independently or saved as presets.
ProBell controllers are labeled with the same reference
letters as the applicator, for easier matching (see FIG. 10
or FIG. 11, page 30 for more detail). See the following
sections for connection information.
If your system is not using all of the ProBell controllers,
see the following sections for specifications and requirements for each air line

2. Using an ohmmeter, verify continuity
between the conductive layer closest to the
applicator and the isolation enclosure

3. Connect the dump hose (D) to a grounded or
isolated waste container. Connect the waterborne hose as in step 1.
To avoid equipment damage
•
Bearing air must be on while the turbine is spinning and must not be turned off until the cup
comes to a complete stop.
•
Bearing air must be filtered to precise requirements. See Air Filters, page 22.
The bearing air provides proper bearing support. Connect the bearing air line to the port marked B on either
the Speed Controller or the Manual Air Controller if only
one controller is present in the system. If both Speed
Controller and Manual Air Controller are present, the
connection must be made to the Speed Controller.
To provide additional protection for the bearing if the
bearing air is turned off before the bell cup comes to a
complete stop, install an air accumulator tank (AT) and a
check valve (CV) in the bearing air line. The accumulator tank (AT) should be 3 gallons (11 liters) or greater.

NOTICE
Turbine air supplies must be regulated and adjusted
to the right pressure before use. Excess air flow will
over speed the turbine and will result in equipment
damage
AT
CV
FIG. 9. Bearing Air Line With Accumulator Tank and
Check Valve
Bearing air requires at least 70 psi (0.48 MPa, 4.8 bar)
pressure at the applicator at all times. A flow volume of 3
scfm is required.
NOTICE
For best performance, maintain 100 psi (0.69 MPa,
6.9 bar) bearing air pressure. Bearing air pressure
of less than 90 psi (0.62 MPa, 6.2 bar) increases the
potential for turbine failure when running at speeds
greater than 50 kRPM.
Bearing Air Return
The turbine air rotates the cup. Connect the turbine air
line to the port marked TA on either the Speed Controller or the Manual Air Controller if only one controller is
present in the system. If both Speed Controller and
Manual Air Controller are present, the connection must
be made to the Speed Controller.
For speed adjustment using a pressure regulator, see
the Turbine Inlet Air Pressure Charts on page 92 for
typical air requirements for a given rotation speed.
If your system does not use the ProBell System Logic
Controller, interlock the turbine air with either the bearing air or the bearing return air, to ensure that the turbine air will flow only if the bearing air pressure is at
least 70 psi (0.48 MPa, 4.8 bar).
If your system does not use the ProBell System Logic
Controller, interlock the turbine air with the brake air so
they cannot flow at the same time.
Braking Air
NOTICE
Use of a bearing air return line will help prevent
equipment damage.
The bearing air return line is connected to a pressure
monitoring device to ensure that adequate bearing air
pressure is maintained. Connect the bearing air return
line to the port marked BR on either the Speed Controller or the Manual Air Controller if only one controller is
present in the system. If both Speed Controller and
Manual Air Controller are present, the connection must
be made to the Speed Controller.
If your system does not use the ProBell System Logic
Controller, bearing air return must be interlocked with
the turbine air so that the turbine air will not flow if the
bearing air return pressure is under 70 psi (0.48 MPa,
4.8 bar).
NOTE: While not advisable, if you choose not to use the
bearing air return line, plug the bearing air return port
(BR) on the applicator.
28
To avoid injury, avoid excessive braking air. A cup
that is not fully seated may disengage from the
shaft.
The braking air slows the turbine speed. Connect the
braking air line to the port marked BK on the Speed
Controller. The speed controller automatically engages
the braking air as needed.
For manual air braking, apply 20 psi (0.14 MPa, 1.4 bar)
air for approximately 5 seconds. This pressure will slow
the bell speed rapidly. Adjust the air pressure and time
as needed for your system to stop cup rotation.
NOTICE
To prevent equipment damage, do not leave braking air
on long enough to rotate the turbine in reverse.
334626K
Installation
If your system does not use the ProBell System Logic
Controller, interlock the turbine air with the brake air so
they cannot flow at the same time.
Shaping Airs
The inner and outer shaping airs provide pattern control
and keep the material particles moving toward the
object being sprayed. Connect the inner shaping air line
to the port marked SI on the Air Controller. Connect the
outer shaping air line to the port marked SO on the Air
Controller.
Paint Trigger Input
The paint trigger input is included on the ProBell Air
Controller (both manual and electronic models). This
isolated input can be used to trigger the paint valve on a
ProBell system from a PLC or robot. See the System
Logic Controller manual 3A3955 to configure how the
paint is triggered in a ProBell system. See the ProBell
Air Controller manual 3A3954 to connect the paint trigger input.
Solvent Valve Trigger (Cup Wash)
See the Shaping Air Consumption Charts, page 94,
for volume requirements. Use filtered, dry air for best finish quality.
The solvent valve trigger provides an air activation signal for the solvent valve and is used to perform a cup
wash. Connect the solvent valve trigger air line to the
port marked ST on the Air Controller.
Maintain an inner and outer shaping air pressure of at
least 10 psi (0.07 MPa, 0.7 bar) at all times to help keep
the bell clean. Use both inner and outer shaping air for
optimal air control. Adjust the pressures to achieve the
best pattern size and velocity for your application.
Interlock the solvent trigger with the turbine air so that
the solvent valve will not open to spray unless the turbine speed is at least 10,000 rpm. The rotation is
required to prevent fluid from flooding the turbine area.
Paint Valve Trigger
The paint valve trigger provides an air activation signal
for the paint valve. Actuate the paint trigger each time a
part is sprayed. The acceptable pressure range is
70-100 psi (0.48-0.69 MPa, 4.8-6.9 bar). Connect the
paint valve trigger air line to the port marked PT on the
Air Controller.
Interlock the paint trigger with the turbine air so the paint
valve will not open to spray unless the turbine speed is
at least 10,000 rpm. The rotation is required to prevent
fluid from flooding the turbine area.
Interlock the solvent trigger with the electrostatics so
that the solvent valve will open to flow only if the electrostatics are turned off and discharged.
Dump Valve Trigger
The dump valve trigger provides an air activation signal
for the dump valve. The dump valve is used to purge the
paint line. Connect the dump valve trigger air line to the
port marked DT on the Air Controller.
Interlock the paint trigger with the conveyor, so the paint
valve will open to spray only when the conveyor is moving.
See ProBell Air Controller manual 3A3954 for options to
create these interlocks.

Step 7. Prepare the Spray Area
Mount Warning Signs
Step 8. Create Required System
Interlocks
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 applicator.
Ventilate the Spray Booth
To help prevent fire, explosion, or electric shock, check
and follow all national, state, and local codes regarding properly interlocking your spray system.
NOTICE
Do not operate the applicator unless ventilation fans
are operating. Provide fresh air ventilation to avoid the
buildup of flammable or toxic vapors when spraying,
flushing, or cleaning the applicator. Interlock the Electrostatic Controller and fluid supply to prevent operation unless ventilating air flow is above the minimum
required value.
Electrically interlock the Electrostatic Controller with the
ventilators so that the electrostatics turn off any time that
the ventilation air flow falls below minimum values.
Check and follow all national, state, and local codes
regarding air exhaust velocity requirements. Verify the
operation of the interlock at least once per year.
NOTE: High-velocity air exhaust will decrease the operating efficiency of the electrostatic system. The minimum allowable air exhaust velocity is 60 ft/minute
(19 linear meters/minute).
To avoid damage to the bearing it is recommended
that the bearing air remain on at all times.
System Interlocks
The following system interlocks are needed to prevent
fire, explosion, electric shock, or equipment damage.
1. Turbine air and bearing air: Interlock so the turbine air will flow only if the air pressure on the bearing air return line is 70 psi (483 kPa) or higher. This
interlock is included in the ProBell System Logic
Controller. Bearing air must be on when the turbine
is operating. Bearing air should be turned off only at
the main air source and only after the cup has
stopped spinning.
2. Paint trigger and turbine air: Interlock so the
applicator will spray only when the turbine is spinning. A minimum of 10K rpm is recommended. This
interlock is included in the ProBell System Logic
Controller.
3. Electrostatic Controller and solvent supply:
Interlock so that electrostatics can be enabled only
when solvent is not flowing in the solvent or paint
lines. See Electrostatic Controller manual 3A3657
for available interlocks.
4. Fluid supply and arc detection: Interlock the fluid
supply to shut off in the event of an arc detection
fault.
5. Braking air and turbine air: Interlock so the braking air flows only when the turbine air is off.
6. Electrostatic Controller and all doors or openings in the spray area: Interlock so the electrostatics turn off any time that entrance is gained. See
Electrostatic Controller manual 3A3657. Check
interlock function weekly.
34
334626K
Installation
7. Conveyor and paint trigger/electrostatics: Interlock so the rotary applicator stops spraying and the
electrostatics turn off if the conveyor stops moving.
8. Electrostatic Controller, fluid supply, and ventilation fans: Interlock so the electrostatics and fluid
supply turn off any time that the ventilation air flow
falls below minimum values. See Electrostatic Controller manual 3A3657.
9. Electrostatic Controller, fluid supply, and fire
control system: Interlock so the electrostatics and
fluid supply turn off any time the automatic fire extinguishing system is activated. See Electrostatic Controller manual 3A3657. Check interlock function
every 6 months.
10. Electrostatic Controller and waterborne isolation system (for waterborne systems): Interlock
so the electrostatics turn off any time entrance to
the isolation enclosure is gained. See Electrostatic
Controller manual 3A3657. Check interlock function
weekly.
Step 9. Ground the Equipment
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.
Grounding provides an escape wire for the electric
current.
When operating the rotary applicator, any ungrounded
objects in the spray location (people, containers, tools,
etc.) can become electrically charged. 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 code for detailed grounding instructions. The following are minimum grounding requirements for a basic electrostatic system.
•
Rotary Applicator: Ground the applicator by connecting a ground wire from the applicator to a true
earth ground. Also ground electrostatic applicators
by connecting the power supply cable to a properly
grounded Electrostatic Controller. The ground wire
may be connected to the grounding lug on the Electrostatic Controller or stand and then connected to a
true earth ground.
•
Control Box Stand: The stand is grounded by connection to the Electrostatic Controller bracket. For
Non-Electrostatic systems, use the ground wire and
clamp provided to connect the stand to a true earth
ground.
•
Air Controller and Speed Controller: If not
mounted on the Control Box Stand, use a ground
wire and clamp to ground to a true earth ground.
•
Electrostatic Controller: Use the ground wire and
clamp provided to connect the Electrostatic Controller to a true earth ground.
•
Pump: Ground the pump by connecting a ground
wire and clamp as described in your separate pump
instruction manual.
•
Voltage Isolation System (for waterborne systems): Follow the grounding procedure in the manufacturer’s instructions.
System Status Output
A system status output is included in the ProBell Speed
Controller. This output indicates when the ProBell system is in Off Mode, such as when an alarm occurs. The
output can be used to interlock system functions with
functions that are not controlled by the ProBell system.
For example: If the paint trigger is outside the ProBell
system, the paint trigger can be interlocked with the system status output to ensure that the paint flow is
stopped in the event of a system alarm. See the ProBell
Speed Controller manual 3A3953 to connect the system
status output.
Optional Interlock Input
An optional interlock input for the ProBell System Logic
Controller can be installed in the ProBell Speed Controller or the ProBell Air Controller. When 24 VDC is applied
to this input, the system goes to Off Mode. Install
Kit 24Z226. See Speed Controller manual 3A3953 or Air
Controller manual 3A3954.
334626K

Installation
•
Fluid Hose (for waterborne systems only): The
hose is grounded through the conductive layer.
Install the hose as instructed. See Fluid Lines for
Electrostatic Waterborne Type Applicators, page
17 and Electrostatic Waterborne Systems, page
24.
•
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 must wear
shoes having conductive or dissipative 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. If nonGraco gloves are worn, cut off fingers or palm area
of gloves to ensure your hand contacts the
grounded gun handle. The measured insulation
resistance of gloves and footwear must not exceed
100 megohm per EN ISO 20344, EN1149-5.
•
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
conductive 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.
36
Check Electrical Grounding
Megohm meter Part No. 241079 is not approved for
use in a hazardous area. To reduce the risk of sparking, do not use the megohm meter to check electrical
grounding unless:
• The rotary applicator has been removed from the
hazardous area;
• Or all spraying devices in the hazardous area are
turned off, ventilation fans in the hazardous area
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, explosion, and electric shock and result in serious injury
and property damage.
Check ground connections daily.

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. Start 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. See Fluid
40
If any fluid leakage from the rotary applicator is
detected, stop spraying immediately. Fluid leakage
into the shroud could cause fire or explosion and
result in serious injury and property damage.
Flush Before First Use
The equipment was tested in fluid at the factory. To
avoid contaminating your fluid, flush the equipment with
a compatible solvent before using the equipment. See

Troubleshooting
Waterborne System Voltage
Loss Troubleshooting
Normal spraying voltage for a system using the
waterborne applicator is 40-55 kV. The system voltage is
lower due to spraying current demands and voltage
isolation system losses.
A loss of spraying voltage can be caused by a problem
with the applicator, fluid hoses, or voltage isolation
system, since all of the system components are
electrically connected through the conductive,
waterborne fluid.
Before troubleshooting or servicing the voltage isolation
system itself, you need to determine which component
in the system is most likely causing a problem. Possible
causes include the following:
Visual Checks
First, check the system for any visible faults or errors to
help isolate whether the applicator, fluid hose or voltage
isolation system has failed.
1. Check that all of the air and fluid tubes and hoses
are properly connected. Make sure waterborne
hose are secured at the proper height at the strain
relief.
2. Check that the voltage isolation system valves and
controls are properly set for operation.
3. Check that the interior of the isolated enclosure is
clean.
4. Check that the voltage isolation system has
sufficient air pressure.
5. Check that the electrostatics are turned on.
Applicator
•
Fluid leakage
•
Dielectric breakdown at the fluid hose connections.
•
Faulty power supply
•
Excessive over spray on applicator surfaces
•
Fluid in the air passages
Waterborne Fluid Hose
•
Dielectric failure of the hose (pin-hole leak in the
PTFE layer)
Voltage Isolation System
•
Fluid leakage
•
Dielectric breakdown of hoses, seals, or
connections
•
Isolators not functioning properly
56
6. Check that the voltage isolation system's enclosure
door is closed and that any safety interlocks are
engaged and working properly.
7. Make sure the voltage isolation system is isolating
the fluid voltage from ground.
8. To eliminate air gaps in the fluid column, spray
enough fluid to purge the air out between the
voltage isolation system and the applicator. An air
gap in the fluid hose can break the electrical
continuity between the applicator and the isolated
fluid supply and cause a low voltage reading at the
isolation system.
9. Check the outside of the applicator for accumulated
overspray. Excessive overspray can create a
conductive path back to a ground. Clean the exterior
of the applicator.
10. Inspect the entire system for any visible fluid
leakage and repair any fluid leaks that are found.
Pay special attention to the following areas:
•
Applicator fluid valves.
•
Fluid hose: check for leakage or any bulges in
the outer cover, which may indicate an internal
leak.
•
Internal voltage isolation system components.
334626K
Troubleshooting
Tests
8. Using the controller, turn on the electrostatics to the
applicator. Observe the voltage and current level on
the controller.
If you still have no voltage, separate the applicator and
fluid hoses from the voltage isolation system and check
whether the applicator and hoses alone will hold voltage
with the following test.
9. If the voltage is 40-55 kV, the applicator power supply is okay, and there is probably a dielectric breakdown somewhere in the fluid hoses or applicator.
Continue with step 10.
1. Flush the system with water and leave the lines
filled with water.
If the voltage is below 40 kV, do the Electrical Troubleshooting, page 55, to check the applicator and power
supply resistance. If those tests show the applicator and
power supply are okay, continue with step 10.
2. Follow the Pressure Relief Procedure, page 43,
which includes Voltage Discharge and Grounding
Procedure.
10. A dielectric breakdown is most likely in one of the
following three areas. Repair or replace the
component that is failing.
3. Disconnect the fluid hoses from the voltage isolation
system.
a. Fluid hoses:
•
Check each hose for leakage or any bulges
in the outer cover, which may indicate a
pin-hole leak through the PTFE layer. Disconnect the fluid hoses from the applicator,
and look for signs of fluid contamination on
the outside of the PTFE portion of the fluid
tube.
•
Inspect the end of each hose connected to
the voltage isolation system. Look for cuts
or nicks.
•
Make sure each hose is properly stripped
(see Electrostatic Waterborne Systems,
page 24). Re-strip or replace the hose.
Avoid allowing any water to leak out of the fluid
hose(s) as that could cause a significant air gap in
the fluid column up to the cup, which can break the
conductivity path and conceal a potential failure
area.
4. Position the end of the hose(s) as far as possible
away from any grounded surface. The end of the
hose must be at least 1 ft. (0.3 m) from any ground.
Make sure that no one is within 3 ft. (0.9 m) of the
end of the hose.
NOTE: The conductive layer of the hose must
remain grounded.
5. Using the controller, turn on the electrostatics to the
applicator. Observe the voltage and current level on
the controller.
•
•
If the voltage is 40 to 55 kV, the applicator and
fluid hose are okay, and the problem is in the
voltage isolation system.
If the spraying voltage is below 40 kV, the
problem is in the applicator or fluid hoses.
b. Fluid hose connection to the applicator:
• A breakdown at the fluid hose connection
joint would be caused by fluid leaking past
the fitting.
11. Clean and dry the fluid tubes, then reassemble the
applicator.
12. Reconnect the fluid hoses.
Check the voltage before filling the applicator with fluid.
6. Discharge the system voltage (see Voltage Discharge and Grounding Procedure, page 44).
7. Flush the fluid hoses and applicator with enough air
to dry out the fluid passages.

Ignitability of Coating Materials
Ignitability of Coating Materials
Per EN 50176
From the Physikalisch-Technische Bundesanstalt, Braunschweig, Germany, June 26, 2019.
General
The fire and explosion protection of spraying systems can be facilitated considerably when processing coating materials with a low portion of solvents and a high flash point (generally water-based paints), provided that the spray cloud
of the coating materials are considered to be non-ignitable. Substantial research has shown that the ignitability of
spray clouds depends on the composition of the coating materials made mainly of water, solvents, and solids. The
following classification has been established:
Non-ignitable coating materials
Coating materials of this group have the following composition:
[% H2O] > 1, 70 + [% LM] + 0,96 x [% ORG], (all in % by weight)
where
H2O: water;
LM: the entire liquid phase, including liquids with flash points above 60°C and those liquids not listed in the
safety data sheet, in which case the entire liquid phase is ignitable in the sprayed state;
ORG: solid phase which is ignitable in the sprayed state (ignitable inorganic or ignitable organic solids)
including the solids which have an ignitable inorganic or ignitable organic coating.
Non-ignitable coating materials act like water in the liquid phase and in the sprayed state. If the rinsing and thinner
liquids correspond to this category, too, no explosion protection is necessary. Coating materials of this group are
classified as being non-ignitable liquid coating material.
A fire extinguishing equipment is not required for spraying systems processing coating materials which are classified
to be non-ignitable. However, this does not affect the fire protection as a whole. Even these coating materials may
resume ignitability after being partially dried. Moreover, water-based coating materials will burn when strongly
exposed to a fire which had been initiated by other sources, and thus present a certain fire load.
