Take the robot base (38) and spacer (43) off the applicator. The following steps are needed to install and connect your system. 1. Connect all lines at the applicator, page 13. 2. Mount the rotary applicator, page 18. 3. Mount the controllers and accessories, page 19. 4. Connect the fluid supply, page 21. 5. Connect the air lines, page 25. 6. Connect the power and communication cables, page 29. 7. Prepare the spray area, page 31. 8. Create required system interlocks, page 31. 9. Ground the equipment, page 32. Step 1. Connect All Lines at the Applicator 2. Remove four screws (44), then take the spacer (43) off of the robot base (38). 43 A total of 14 connections are needed for ProBell operation. If required, attach an adapter plate to the robot arm before connecting fluid and air lines. See Accessories, page 78, for a list of adapter plates. NOTE: All lines must run through the robot, the robot adapter plate (if one is needed), the spacer (43), and into the robot base (38) before connection to the applicator. 44 38 TIP: Connect the lines in the order shown in this section. Label each line and bundle into groups, to avoid confusion later when the lines are connected to the fluid supply, air supply, and other system components. The applicator ships assembled. Follow these steps to take the base and spacer off the applicator for easiest hose connections. 1. Use the spanner wrench tool (52) to loosen the quick disconnect ring (29). Push the ring toward the 334626F 13 Installation Fluid Lines for Solventborne Materials 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. 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. 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, a plug kit (25C288) is available to plug the dump passage. Fluid Lines for Waterborne Materials 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 32. See Accessories for a list of available waterborne hoses. 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.). 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 (Continued), page 90, 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. FIG. 3. Fluid Connections 14 334626F Installation Air Lines A total of nine air line connections are needed. Begin at the center and work out. Remember to label each line, and bundle into groups. 86 87 88 7.625 in. (19.4 cm) R FIG. 4. Air Connections 3. The applicator end of the waterborne hoses come stripped to the correct dimensions. On the shielded hose the conductive layer (W) covering the PTFE tube (Y) and the outer cover (X) are trimmed to the same length. The unshielded hose has no conductive layer. U=5.8 in. (14.7 cm) 1. Connect the larger air supply lines first. Use 8 mm (5/16 in.) OD tube with 1 mm (0.04 in) wall to minimize pressure drop. a. Connect the bearing air to port B. b. Connect the inner shaping air to port SI. c. Connect the outer shaping air to port SO. d. Connect the turbine air to port TA. e. Connect the braking air to port BK. 2. Connect the three trigger air lines next- the paint valve trigger (PT), the solvent valve trigger (ST), and the dump valve trigger (DT). These lines can be smaller because they provide only an air activation signal. Use 4 mm (5/32 in.) tubing. 3. Next, connect the bearing air return (BR), also a 4 mm (5/32 in.) tube. 334626F 15 Installation Power Supply Cable Connect the 4-pin end of the power supply cable to connector R on the applicator. 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 78, 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.

See Turbine Inlet Air Pressure Charts, page 84. 17 Installation 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 82. If required, attach an adapter plate to the robot arm before connecting fluid and air lines. See Accessories, page 78, 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 disconnect ring (29) into place. Tighten with the spanner wrench tool (52) to secure the applicator to the robot base. 43 Solventborne 38 44 43 Waterborne 38 44 FIG. 6 Mount the Applicator 18 334626F Installation 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. 334626F 19 Installation • 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 that is heated above 120° F (49° C) will damage filter elements. FIG. 7. Air Filters Table 1.

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. 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). 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). 20 334626F Installation Step 4. Connect the Fluid Supply Connect fluid lines at the applicator first. See Step 1. Connect All Lines at the Applicator, page 13. must also be connected to a regulated air supply to purge the cup wash passages with air. An air purge is recommended for use with conductive solvents to improve electrostatic performance Solventborne 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. NOTE: Not purging the lines of conductive solvents may cause low electrostatic voltage or system errors. Waterborne Systems b. Dump Hose (optional): The fluid hose connected to port D on the applicator must go to a grounded waste container. 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. 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 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 334626F - Use only approved Graco Waterborne fluid hoses. - Unshielded waterborne fluid hoses must be routed such that a minimum distance of 0.25 cm/kV is maintained between the hose and 21 Installation grounded surfaces. - The conductive layer of shielded hoses must be grounded at the isolation system. • 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. 22 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. 334626F Installation • A shielded hose consists of an inner PTFE tube (Y), a conductive layer covering the PTFE tube (W), and an outer cover (X). e. Waterborne Fluid Hoses Hose-Stripping Requirements Ref. Shielded Unshielded U 14.5 in. 368 mm 14.5 in. V 0.75 in. 19 mm 368 mm NA • 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. 334626F 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). 23 Installation • 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) 3. Connect the dump hose (D) to a grounded or isolated waste container. Connect the waterborne hose as in step 1. X Y W Z T X W T 2. Using an ohmmeter, verify continuity between the conductive layer closest to the applicator and the isolation enclosure ground. 24 334626F Installation Step 5. Connect the Air Lines Connect all air lines to the applicator first (See Step 1. Connect All Lines at the Applicator, page 13). 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 28). 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. 9 or FIG. 10, page 27 for more detail). See the following sections for connection information. Bearing Air Line AT CV If your system is not using all of the ProBell controllers, see the following sections for specifications and requirements for each air line NOTICE Take great care to connect the air lines to the correct ports on the control equipment. Incorrect air line connections will damage the applicator. Bearing Air NOTICE 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 19. 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. FIG. 8 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 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. 334626F 25 Installation Turbine Air 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 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 84 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 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. 26 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. See the Shaping Air Consumption Charts, page 86, for volume requirements. Use filtered, dry air for best finish quality. Maintain an inner 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 pattern control. Adjust the pressures to achieve the best pattern for your application. Increase shaping air pressures to reduce the pattern size. 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 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. 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. 334626F Installation Solvent Valve Trigger (Cup Wash) 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. 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. 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 Speed Controller 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. Auxiliary Ports Three auxiliary ports are provided on the Graco Air Controllers for other customized system needs. The user might use one to trigger a valve, for example, or to connect a shutoff signal to stop the conveyor system.

Integrate the electrostatics. Integration of the electrostatic enable function typically depends on a part detection system. Two options are common: • • Use the electrostatic enable digital input on the Discrete I/O interface of the ProBell Electrostatic Controller. Connect per controller manual 3A3657. Provide a command from an external controller to the ProBell System Logic Controller to set the electrostatic enable register via a communication network. See Manual 3A3955.

The kit includes instructions for conversion and installation. Graco CAN Communication Cables for System Components System components communicate information via Graco CAN cables. No CAN cables connect to the applicator. But, several are needed to interconnect other system components. Use CAN cables to network the Electrostatic Controller, Air Controller, Speed Controller, and the Graco System Logic Controller (if used) in series, as shown in the figure. One power supply is required in the CAN network, typically mounted on the speed controller. See page 78 for a list of available CAN cables. To connect the ProBell system to an outside communication network, purchase and install a gateway (see 3A4384 CGM Installation Kit 24Z574) and configure per the System Logic Controller manual 3A3955. Speed Controller Connect the fiber optic cable to port F on the applicator and to port F on the speed controller. The amount of fiber extending past the nut should be 0.440 in. (11.2 mm) on the speed controller side. On the applicator side, the amount of extended fiber is 1.48 in. (37.6 mm). If you need to cut or repair the cable, use the tool included with the cable to cut as shown. Speed Controller End 0.440 in. (11.2 mm) Applicator End 1.48 in.

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. 334626F 31 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. 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. 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. 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. System Status Output • Rotary Applicator: Ground the applicator by connecting the power supply cable to a properly grounded Electrostatic Controller and connecting the ground wire to a true earth ground. The ground wire may be connected to the grounding lug on the electrostatic controller and then connected to a true earth ground. • Control Box Stand: The stand is grounded by connection to the Electrostatic Controller bracket. • 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. • Fluid Hose (for waterborne systems only): The hose is grounded through the conductive layer. Install the hose as instructed. See Fluid Lines for Waterborne Materials, page 14 and Waterborne Systems, page 21. 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. 32 334626F Installation • 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. 334626F 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.

Go through the Pre-Operation Checklist daily, before each use. All System Types All operators are properly trained to safely operate an automatic electrostatic rotary applicator system as instructed in this manual. All operators are trained in the Pressure Relief Procedure on page 40. The warning sign provided with the rotary applicator 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 Step 9. Ground the Equipment on page 32. The rotary applicator’s mechanical and electrical components are in good condition. Ventilation fans are operating properly. All Setup is complete. Electrostatics are off and voltage is discharged according to Voltage Discharge and Grounding Procedure, page 40, before entering the spray area for any cleaning or maintenance work. Waterborne systems only Electrostatics are off and voltage is discharged according to the Voltage Discharge and Grounding Procedure, page 40 before any person enters the isolation enclosure, before cleaning, and before performing any maintenance or repair. The Graco waterborne fluid hoses (shielded or unshielded) are in good condition with no cuts or abrasions of the PTFE tube. Replace fluid hose if damaged. All fluids used meet one of the following flammability requirements: • Workpiece hangers are clean and grounded. • All debris is removed from the spray area, including flammable fluids and rags. Material does not sustain burning in accordance with the Standard Test Method for Sustained Burning of Liquid Mixtures, ASTM D4206. Material is classified as non-ignitable or hard to ignite as defined by EN 50176. 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. 36 334626F Operation Check Fluid Resistivity ate nozzle size. Spray Procedures 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, and 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. Readings of 20 megohms-cm and above provide the best electrostatic results and are recommended. 1-7 Longer fluid hose may be needed* Megohms-cm 7-20 20-200 200-2000 Good Good Best electrostatic electrostatic results results * Included in kit #25A878. To reduce the risk of electric shock and to avoid injury due to contact with the spinning cup, do not enter the spray area during rotary applicator operation. 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 Flushing, page 39. Load Material 1. Put the system in Purge mode. In this mode: 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 Flow Rate Charts, page 88 to select the appropri- 334626F a. Ensure that electrostatics cannot be enabled. b. The bell should be rotating at least 10k rpm. c. The Inner Shaping Air should be a minimum of 10 psi (0.7 bar) to help keep the applicator clean. 2. Supply paint to the paint line P. 3. Actuate the dump valve trigger (DT) until paint reaches the applicator. Actuate the paint valve trigger (PT) to load the paint to the front of the applicator. NOTE: With this method, paint is returned through the dump line, rather than exiting out the front of the applicator. Paint remains in the dump line until the system is flushed. If your material has a low pot life, actuate the paint valve trigger (PT) to load paint. 4. Follow the Cup Wash procedure, page 39. 37 Operation Check Flow Rate sure Charts, page 84, for the required pressure to achieve a given speed. These instructions begin with material loaded. 1. Follow the Cup Wash procedure, page 39. d. Actuate the paint valve trigger (PT). 2. Put the system in Maintenance Mode. In this mode: e. Increase the speed (or increase the turbine air pressure slowly) for finer atomization. • • • • The electrostatics are off. The shaping air is off. The turbine air is off (not rotating). The bearing air may remain on. f. Decrease the speed (or decrease the turbine air pressure slowly) for coarser atomization. 3. Remove cup and air cap. See 15 mm or 30 mm Cup, page 54, or 50 mm Cup, page 54. NOTE: Speed can be changed with the applicator triggered or not triggered. 4. Actuate the paint valve trigger (PT). 4. Adjust the pattern size: 5. Measure the flow into a container. Use a stop watch to measure the time. Calculate the flow rate. 6. To increase the flow rate: • Increase the regulated fluid pressure of the material. • Increase the size of the fluid nozzle. • Reduce the viscosity of the material. • Use a larger diameter fluid hose up to the bell. To decrease the flow rate: • Reduce the regulated fluid pressure of the material. • Reduce the size of the fluid nozzle. 7. Reinstall the cup and air cap. See 15 mm or 30 mm Cup, page 54, or 50 mm Cup, page 54. Adjust the Spray Pattern a. Start with 10 psi (0.7 bar) on both the inner and outer shaping airs (SI and SO). b. Increase the outer shaping air (SO) to reduce the pattern size or to improve applicator cleanliness (reduce wrap-back). c. Increase the inner shaping air (SI) for additional pattern control. 5. Adjust the electrostatics: a. Start with the maximum settings (100 kV, 150 µA for Solventborne models; 60kV, 150 µA for Waterborne models). b. Decrease the voltage if test parts show evidence of thick edges or poorly covered recess areas (the Faraday effect). c. Increase the voltage for improved wrap. 1. Put the system in Spray mode. 2. Select Preset 0 so the spray parameters can be independently adjusted. 3. Adjust the atomization: a. Set the inner shaping air (SI) and outer shaping air (SO) to at least 10 psi (0.7 bar) to keep the bell clean. 38 b. Set the speed to 25K rpm. c. If your system does not have a speed controller, start with the turbine air (TA) set at 0 and increase very slowly. Make sure not to over speed the turbine. See Turbine Inlet Air Pres- 6. Follow the Cup Wash procedure, page 39. Spray a Part 1. Put the system in Spray mode. In this mode: a. Inner and outer shaping airs (SI and SO) are on. b. The turbine is spinning at the desired speed. 2. Position a part, or position the applicator, for material application. 334626F Operation 3. Turn on the electrostatics. The Safe Position input and other required interlocks must be satisfied. Flushing 4. Actuate the paint valve trigger (PT) until desired coverage is achieved. To avoid fire, explosion, and electric shock: • Always turn off the electrostatics and discharge voltage when flushing, cleaning, or servicing equipment. • Always ground the equipment and waste container. • Flush the equipment only in a well-ventilated area. • Use only Group IIA materials. Non-ignitable fluids are preferred. • To avoid static sparking and injury from splashing, always flush at the lowest possible pressure. NOTE: Excessive paint may wrap back toward the applicator if the applicator is sprayed without a target present. 5. When finished, turn off the paint valve trigger first. 6. Then, turn off the electrostatics. 7. Short Breaks: Leave the shaping airs on and the turbine at speed. Longer Breaks: Follow the Cup Wash procedure, page 39. Put the system in Idle mode, which reduces the turbine speed and shaping airs to conserve energy. • Flush before changing fluids, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment. • Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary. • Flush with a fluid that is compatible with the fluid being dispensed and the equipment’s wetted parts. Cup Wash Follow this cup wash procedure whenever you are done spraying parts, and as needed between parts depending on the material being sprayed and the rate of build-up. Some materials will require frequent cup washing. 1. Put the system in Purge mode. In this mode: a. Ensure that electrostatics cannot be enabled. b. The bell should be rotating at least 10k rpm. c. The inner shaping air (SI) should be a minimum of 10 psi (0.7 bar) to help keep the applicator clean. 2. Activate the solvent valve trigger (ST). NOTICE Use the lowest practical solvent pressure to perform flushing and cup wash procedures. Excessive solvent flow can cause fluid to flood the turbine and damage it. 1. Put the system in Purge mode. In this mode: a. Ensure that electrostatics cannot be enabled. b. The bell should be rotating at least 10k rpm. c. The inner shaping air (SI) should be a minimum of 10 psi (0.7 bar) to help keep the applicator clean. 3. Use air to purge the solvent. a.

Actuate the dump valve trigger (DT) to flush the lines to the applicator. Close the dump valve when clear solvent exits the dump line. (Actuate the Paint trigger if the dump valve is not being used.) 1. Turn off the electrostatics. Complete Step 1 of the Voltage Discharge and Grounding Procedure. 2. Shut off the fluid and solvent supply. 4. Actuate the paint trigger (PT) to flush the fluid tube and nozzle. 5. Actuate the solvent valve trigger (ST) to wash the cup. NOTE: If you need to purge all solvent, proceed with Step 6. 6. Use air to purge the solvent. a. Provide air to the paint line P. b. Actuate the dump valve trigger (DT) to purge the lines. c. Actuate the paint valve trigger (PT) to purge the applicator. d. Provide air to the solvent line S. e. Actuate the solvent valve trigger (ST) to purge the cup wash solvent. 3. Relieve the paint pressure. Actuate the dump valve trigger (DT) to relieve pressure in the paint and dump lines. If your system does not have a dump valve, actuate the paint valve trigger (PT). 4. Relieve Solvent Pressure. Actuate the solvent valve trigger (ST) to relieve pressure in the solvent line. 5. Turn off the turbine air and the shaping airs. Put the system in Off mode. 6. After the bell has stopped spinning, turn off the main air supply. 7. Disable the electrostatics and verify the voltage has been discharged. Complete Steps 2-4 of the Voltage Discharge and Grounding Procedure. Voltage Discharge and Grounding Procedure Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment. Follow these basic steps in the order shown to relieve the system pressure. The exact procedure to accomplish each step may vary based on your system design. Be certain that all steps are completed. The system is charged with high voltage until the voltage is discharged. Contact with the charged components of the applicator will cause an electric shock. For Waterborne systems, contact with the charge fluid supply system also will cause an electric shock. To avoid an electric shock, follow this procedure: • • • • before entering the spray area whenever you are instructed to discharge the voltage before cleaning or servicing the system equipment or before opening the isolation enclosure for the isolated fluid supply. NOTE: Turn off the main air supply (bearing air) only after the cup has stopped spinning. 40 334626F Operation b. To avoid fire or explosion during the test, all spraying devices in the hazardous area must be turned off and ventilation fans in the hazardous area must be operating. Conduct the test only when no flammable vapors are present in the area (such as open solvent containers or fumes from spraying). NOTE: An accessory grounding rod, part No. 210084, is available to discharge any voltage remaining on a system component. For Waterborne Systems: Discharge the voltage at the voltage isolation system by following the procedure specified in the voltage isolation system instruction manual. Touch the pump, supply pail, and applicator air cap cover with a grounded rod to make sure the voltage has been discharged. If you see an arc, verify that the electrostatics are turned off. Increase the discharge time. See Electrical Troubleshooting, page 50, or the voltage isolation system manual for other possible problems. The default discharge time is 60 seconds. Resolve the problem before proceeding. 5. Test voltage discharge weekly. 1. Turn off the electrostatics by pressing on the Electrostatic Controller, by using an Electrostatic Enable I/O signal, or by using CAN communication. Switching to Purge mode also will shut off the electrostatics. Wait the amount of time set for your system to discharge. To avoid fire or explosion, or electric shock, always wait for the full discharge time to elapse. Once the electrostatics are turned off, the display no longer tracks or displays the actual voltage. Do not use the controller display to determine if the system is discharged. Shutdown 1. Flush if needed. See Flushing, page 39. 2. Follow the Pressure Relief Procedure, page 40, which includes Voltage Discharge and Grounding. 3. Clean the cup and exterior of the applicator. See Clean the Air Cap and Cup, page 46. See also, Clean the Outside of the Rotary Applicator, page 47. NOTE: The procedure to set the discharge timer is found in the directions for Setup Screen 10 in the Electrostatic Controller manual (3A3657). 2. Put the system in Off mode. 3. Disable the electrostatics by powering off the Electrostatic Controller (set to off). NOTE: Electrostatics also can be disabled by removing an interlock, if preferred. An error will occur. When the procedure is finished, clear error to restart. 4. Verify that the system has discharged. a. For Solventborne Systems: Touch the air cap cover (19) with a grounded rod to make sure the voltage has been discharged. If you see an arc, verify that the electrostatics are turned off. Increase the discharge time, or see Electrical Troubleshooting, page 50. The default discharge time is 5 seconds. Resolve the problem before proceeding. 334626F 41 Maintenance Maintenance Check for Fluid Leakage Installing and servicing this equipment requires access to parts which may cause an electric shock or other serious injury if the work is not performed properly. Do not install or repair this equipment unless you are trained and qualified. Contact with the charged components of the rotary applicator will cause an electric shock. Contact with a rotating cup also may cause injury. Do not touch the bell or come within 3 ft. (0.9 m) of the front of the applicator during operation.

Waterborne Systems: See Waterborne System Voltage Loss Troubleshooting, page 51, for possible causes and solutions. 50 334626F 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: 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) 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. 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: Voltage Isolation System • Applicator fluid valves. • Fluid leakage • • Dielectric breakdown of hoses, seals, or connections Fluid hose: check for leakage or any bulges in the outer cover, which may indicate an internal leak. • Internal voltage isolation system components. • Isolators not functioning properly 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 334626F 51 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 50, 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 40, which includes Voltage Discharge and Grounding. 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 Waterborne Systems, page 21). 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. 6. Discharge the system voltage (see Voltage Discharge and Grounding Procedure, page 40). 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. 7. Flush the fluid hoses and applicator with enough air to dry out the fluid passages. 52 334626F Repair Repair Prepare for Service 2. Follow the Pressure Relief Procedure, page 40, which includes Voltage Discharge and Grounding. 3. Clean the applicator. See Daily Care and Cleaning Checklist, page 42. Installing and servicing this equipment requires access to parts which may cause an electric shock or other serious injury if the work is not performed properly. Do not install or repair this equipment unless you are trained and qualified. 4. Use the quick disconnect to remove the applicator from the robot base. Perform service or repair at a work bench. Contact with the charged components of the rotary applicator will cause an electric shock. Contact with a rotating cup also may cause injury. Do not touch the bell or come within 3 ft. (0.9 m) of the front of the applicator during operation. To reduce the risk of an injury, follow the Pressure Relief Procedure, page 40, before checking or servicing any part of the system, and whenever you are instructed to relieve the pressure. NOTES: • Check all possible remedies in Troubleshooting, page 48, before disassembling the applicator. • Lightly lubricate o-rings and seals with non-silicone grease. Order Part No. 111265 Lubricant. Do not over-lubricate. • Only use genuine Graco parts. 5. Remove the shroud (45) by pulling it straight back. The shroud is spring loaded for quick removal and replacement. 6.
