Explosion Hazard / Incompatible Materials
Toxic Substances
Halogenated hydrocarbon solvents for example: methylene chloride and 1,1,1,-Trichloro-ethane are not chemically compatible with the aluminum that might be used in many system components. The chemical reaction caused by these solvents reacting with aluminum can become violent and lead to an equipment explosion.
Certain material may be harmful if inhaled, or if there is contact with the skin.
Aluminum is widely used in other spray application equipment - such as material pumps, regulators, triggering valves, etc. Halogenated hydrocarbon solvents must never be used with aluminum equipment during spraying, ushing, or cleaning. Read the label or data sheet for the material you intend to spray. If in doubt as to whether or not a coating or cleaning material is compatible, contact your material supplier. Any other type of solvent may be used with aluminum equipment.
Follow the requirements of the Material Safety Data Sheet supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the air free of accumulations of toxic materials.
Use a mask or respirator whenever there is a chance of inhaling sprayed materials. The mask must be compatible with the material being sprayed and its concentration. Equipment must be as prescribed by an industrial hygienist or safety expert, and be NIOSH approved.

GENERAL SAFETY GUIDELINES
• The articles being coated MUST be grounded at all times.
W A R N I N G
!
> The simple safety measures outlined here
are vital. Failure to observe them could cause a spark capable of starting a re.
• All components of the applicator system (except the atomizing head) MUST be grounded at all times.
• All contact points MUST be free of any accumulation of nonconductive residue.
• All electrically conductive objects, especially solvent containers within the spray area, MUST be either removed or grounded.
Any tool, if used improperly, can be dangerous. Safety is ultimately the responsibility of those using a tool. In like manner, safe operation of electrostatic coat­ing processes is the responsibility of those who use such processes and those who operate electrostatic coating equipment. Procedures to be followed on conducting electrostatic coating operations safely are outlined in the Ransburg brochure IL-247: "Operating Your Electrostatic Coating System Safely". Additional copies are available from Ransburg upon request. All personnel connected with coating operations should read and understand this brochure. It is most important that the equipment operators and supervisory personnel understand the requirements for safe operation.
W A R N I N G
!
Additional cards summarizing these safety require­ments are available from Ransburg on request. These cards should be posted in the spraying area so that they can be readily referred to and serve as a reminder to personnel in that area of responsibility. Additional copies of the sign SL-00-07: "Cleaning Safety Require­ments" are available upon request.
Each user should examine his own coating operation, develop his own safety program, and ensure that his workers follow correct procedures. Ransburg hopes that the information it provides is helpful to the user in establishing such a program.
In addition to the available cards, labels, brochures, and service manuals, the user should consult other standards and recognized safety authorities. Section
1910.107 of the regulations established under the Occupational Safety and Health Act [OSHA] apply to spray nishing operations. Paragraph (i) specically applies to electrostatic hand spraying equipment. NFPA No. 33 "Spray Application", is another standard for spray painting operations. Chapters 9, 10, and 13 are specically applicable to electrostatic coat­ing. Copies of NFPA No. 33 are available from the National Fire Protection Association, Batterymarch Park, Quincy, Mass. 02269 (at nominal cost).
The National Fire Protection Association also pub­lishes standards other than NFPA No. 33 relating to the control of re hazards. NFPA No. 33 specically refers to the following bulletins of the National Fire Protection Association as applicable to coating op­erations:
NFPA No.63: Dust Explosion, Industrial Plants NFPA No.70: National Electrical Code NFPA No.86A: Ovens and Furnaces NFPA No.91: Blower and Exhaust Systems NFPA No.654: Dust Explosions, Plastics Industry NFPA No.77: Static Electricity, also contains much useful information. Copies of these brochures will be helpful in arriving at a program for safe operation.
> If ANY symptom of improper operation
occurs, suspend use of the unit until the problem has been diagnosed and corrected. See the appropriate "Troubleshooting Guide" or contact your Ransburg representative.
LN-9240-02.1
Local codes and authorities also have standards to be followed in the operation of your spray equipment. Your insurance carrier will be helpful in answering questions that arise in your development of spray coating procedures.

Turbodisk 2 - Safety
All personnel MUST read and understand the following Ransburg Safety Publications:
IL-247: Operating Your Electrostatic Coating System Safely SL-77-01: Personnel Grounding
Ransburg also suggests that all personnel read the HEW publication "Spray Painting: Good Practices for Employees", number (NIOSH) 78-178 available from the regional NIOSH oce or the U.S. Government Printing Oce.
NIOSH and OSHA regional offices can provide information on OCCUPATIONAL SAFETY AND HEALTH ACT, including questions on standards interpretations, voluntary compliance information, copies of the OSHA Standards, OSHA Act, Employee Rights Posting Notice and Publications.
Personnel
• All personnel should read and understand local codes, appropriate NFPA bulletins, OSHA Act of 1970, and this service manual.
Parts
• Articles being painted MUST be grounded at ALL times. Paint MUST NEVER be permitted to accumulate on workholders, particularly on points where workholders touch conveyor. Hooks MUST be clean to ensure proper contact. It is advisable to have extra sets of workholders to enable cleaning of the sets not being used at regular intervals. Areas of hanger contact should be sharp points or edges where possible.
• All electrically conductive objects within the spray area (including spray booth, paint tank, and conveyor) MUST BE GROUNDED. This requirement applies to the solvent safety container, paint containers, wash cans, and all other objects in the area.
Ventilation
We recommend interlocking the ventilation with the spraying equipment to ensure proper ventilation when equipment is in operation. See NFPA Bulletin No. 33.
• Personnel working in the spray area MUST be adequately grounded. Insulated shoes such as rubber, composition, or cork soles should NOT be worn unless an alternate grounding method is provided. (See Ransburg Bulletin SL-77-01, "Personnel Grounding".)
W A R N I N G
!
> ALWAYS turn power supply OFF prior to
cleaning or working on equipment.
> ENSURE that the grounding hook has been
properly secured to the motor housing.
• Personnel working on applicators MUST always be sure that the high voltage is o, the rotator has stopped and that the grounding hook has been properly secured to the motor housing.
Housekeeping
• Good housekeeping is essential to safe operation. Clean-up and maintenance schedules should be established by the user, based on observations of the initial production operations. Maintenance and safety cards should be posted in clear view of the operator.
• Normal re protection measures are required. These include proper storage of paints, solvents, and waste, plus ready access to re extinguishing equipment. For details, consult NFPA Bulletins No. 30, 33, 70 and 77, your local re codes, local paint equipment standards, OSHA Act of 1970, and your insurance carrier’s recommendations.
Floor Covering and Masking
If it is necessary to cover booth ooring, Ransburg suggests that the user employ a material which will NOT support combustion, such as Spark Gard Grade BWA-100.

TM
2 Applicator
GENERAL DESCRIPTION
The Turbodisk 2 Applicator, because of it's high rotational speed, produces finer atomization, improved quality, and higher transfer eciency with any of the wide variety of coating materials (such as waterborne and high solids) used in production nishing operations. It's speed is controlled by varying the drive air. The applicator assembly is designed for use on vertical overhead mounted reciprocators.
Quick Disconnect
-REFER TO FIGURES 16, 17, & 26
The Turbodisk 2 Applicator is a quick disconnect design that allows the lower uid section that carries all the uid/ air controls to be separated from the upper section carrying the tubing supply lines. The incoming air lines, uid lines, high voltage cable, and ber optic cable are connected to the ttings provided on the upper xed bulkhead plate. Each bulkhead plate (upper and lower) utilizes special male and female ttings with o-rings that seal the uid and air line passages when both sections are assembled together. Two latching mechanisms have been incorporated into the design allowing the lower section to be supported while the operator tightens or loosens the retaining screws that hold the upper and lower sections together. Alignment arrows engraved into the side of the bulkhead plates provide for quick visual assembly orientation.
• The easily removable lower fairing, turbine air motor assembly, and the externally mounted regulators and uid valves, make o line maintenance more ecient and economical.
• Control air lines are color coded for ease of identication.
• Higher uid delivery rates can be achieved using a dual feed uid system.
• High ow regulators and uid valves provide for simultaneous paint push out while solvent washes the feed tube and disk.
8
Conical Disk Assembly
The Turbodisk 2 Applicator uses conical disk assemblies that are made from high grade aluminum construction and are force balanced to .10 gramsin or better. With the patented serrated edge, these disks come in sizes of 6, 9, and 12 inch diameters.
LN-9240-02.1
Turbodisk 2 - Introduction
Turbodisk 2 Fairing
-REFER TO FIGURE 24
The Turbodisk 2 Applicator fairing is required for safe operation. The two piece fairing provides high voltage isolation from the metal rotator assembly and valve components, as well as ease of cleaning and maintenance. Provided on the fairing are (4) draw latches which allow for easy on/o removal of the lower fairing.

TYPICAL SPEED CHART (RPM's)
-REFER TO FIGURES 1 & 23
The following represents data collected under lab conditions. Flow meters were installed on each of the two 3/8 I.D. heated air lines used to supply the Turbodisk 2 turbine motor. The airow through each ow meter was recorded and added together to obtain the total air ow through the system. The speed of the disk was monitored through the means of a PulseTrack™ system. The air heater was set at 120 degrees during all data collection.
Rotational speeds are unloaded and can be expected to drop 20 to 30% when under a uid load condition. Heated turbine air increases eciency of motor up to 10%. This chart should be used as a guide ONLY. Speeds will vary due to rotator wear, tubing size or lengths, etc.

Turbodisk 2 - Installation
INSTALLATION
EQUIPMENT
This system should be installed by, or under the supervision of an Ransburg representative. Should the need arise to replace any component assembly within the system, contact your Ransburg representative.
This manual concerns normal operation, maintenance, and service of the specied applicator assemblies. The air and uid connections vary with dierent models and installations. This manual deals primarily with those at, or within the assembly.
AIR CONTROL
-REFER TO FIGURE 2
Air control of the applicator is from a standard Ransburg air logic panel, which includes two lters (one 40 micron lter located at the air logic station and one 5 micron lter located at the inlet of the in­line air heater panel). Clean, dry factory air must be provided to the inlet lter of the air logic station via a minimum 1/4-inch I.D. pipe and to the inlet lter of the heater panel via a minimum 3/4-inch I.D. pipe.
MOUNTING
-REFER TO FIGURE 17 & 24
The Turbodisk 2 assembly is mounted on the reciprocator using (4) 5/16-18 screws provided on the ram ange. Loosening (2) 1/4-20 screws on the same ram ange will allow the assembly to rotate. Position the Turbodisk 2 assembly so that the strain relief boot is positioned toward the incoming uid and air lines and retighten.

Turbodisk 2 - Operation
OPERATION
!
C A U T I O N
> Fluids and lubricants used in this system
must contain NO silicones!
> Do NOT operate the unit without an atomizer
disk! Without a disk, overspeed, resulting in premature bearing failure, is possible.
> The air supplied to the motor must be dry,
clean and free of oil or moisture. The atmospheric dew point should be 10oF or less. The air heater used should be adjusted only high enough to prevent condensation from forming on the motor housing or at the exhaust port.
W A R N I N G
!
> Operators must be fully trained in safe
operation of electrostatic equipment. Operators must read all instructions and safety precautions prior to using this equipment (See NFPA 33, Chapter 16).
As with any spray nishing system, operation of the Turbodisk 2 involves properly setting the operating parameters to obtain the best nish quality for the coating material being sprayed, while maintaining correct operation and reliability of the equipment used. Adjustments to operating parameters, which cover spraying, cleaning and on/o control, include:
• Fluid Type
• Fluid Flow Rate
• Turbine Speed
• Electrostatic Voltage
• Target Distance
COATING MATERIALS
The Turbodisk 2 can be used with a broad range of coating material conductivities. However, with waterborne paints, it may be necessary to isolate the paint supply from ground.
W A R N I N G
!
> Isolated uid supplies using either waterborne
or highly conductive solvent base coatings can produce hazardous high voltage discharges which can cause res or injury to personnel.
FLUID FLOW CONTROL
-REFER TO FIGURES 19-22
Fluid flow control is dependent on the valve conguration of the Turbodisk 2. If the Turbodisk 2 is congured with no valves or a 3-way valve, uid ow is controlled externally at the paint source. If the Turbodisk 2 is equipped with a regulator, uid ow can be controlled via the air pilot signal. The high ow and low ow regulators each have procedures on how to control and deliver consistent uid ows. For more information on controlling the uid delivery using regulators, refer to that specic manual which is included with the system.
To check uid ow rates, the disk must be removed. See the maintenance section for removal procedure. The uid can then be manually triggered to measure actual ow in a graduated beaker over a specied time period.
W A R N I N G
!
> Danger of shock and/or personal injury can
occur. Proper grounding procedures, which are outlined in the Ransburg safety bulletins, must be followed. Personnel must never work near or perform work on the turbine when the turbine is spinning or when high voltage is on.

FLUID VALVE CONTROL
Trigger and Dump
-REFER TO FIGURES 4 & 25
Turbodisk 2 - Operation
The uid valves in the Turbodisk 2 are actuated by an air signal. The air pressure must exceed 70 psi to assure proper actuation of the valve. Applying air to the valve actuator turns on the uid ow for that valve.
The trigger valve controls the paint ow to the disk. When actuated, paint ows through the valve to the uid tube. The disk should be spinning at a RPM speed that is fast enough, (that when uid is turned on) to enable the uid to ow through the disk paint passage holes and be atomized.
The dump valve controls the paint ow through the dump line. When actuated, paint ow is directed to the dump return line. This provides a method of rapidly removing paint from the incoming line for cleaning
and/or color change. Normally, the dump valve is not actuated at the same time as the paint trigger valve since the trigger valve is intended to cause the uid ow to the disk at the prescribed input pressure.

Turbodisk 2 - Operation
TURBINE SPEED
Turbine speed is determined by the drive air pressure at the rotary atomizer and uid ow rate.
Turbine speed can be closed loop controlled using the ber optic speed transmitter mounted at the back of the turbine rotator assembly as a speed input to remote speed controls such as the PulseTrack.
NOTE
> The disk rotational speed determines
the quality of atomization and can be varied for dierent ow rates and viscosities. For optimum transfer eciency and spray pattern control, the disk rotational speed should be set at the minimum required speed to achieve proper atomization. Excessive speed reduces transfer eciency!
W A R N I N G
!
> Do not exceed the maximum rated speed of
40,000 RPM for the 6 inch conical disk and 27,000 RPM for the 6 inch uni-disk.
Atomizers
-REFER TO FIGURE 5
W A R N I N G
!
> Never operate any disk atomizer in excess of
it's maximum rated speed ("K" number) as listed in the service manual. Excessive speed may cause the disk to disintegrate, causing serious damage and/or injury.
All atomizers manufactured after April 6, 1982, bear a “K” number. That number indicates the maximum safe rotation speed for that series in tens of thousands. For example:
9K = 9,000 RPM maximum safe speed, 40K = 40,000 RPM, etc.
If you have an atomizer that does not have a “K” number, contact your Ransburg representative for its maximum safe operating speed.

Turbodisk 2 - Operation
ELECTROSTATIC VOLTAGE
In the system, the high voltage is supplied to the Turbodisk 2 by either the MicroPak Industrial power supply system or Voltage Master series power supplies.
The MicroPak Indus trial power supply uses proven high voltage generator technology that is microprocessor controlled for diagnostics and communication. The controller is packaged in standard rack mounted Eurocard format for easy access and system integration.
The Voltage Master power supplies are general purpose heavy duty power supplies with years of proven reliability. They have variable voltage control, many safety features, and remote analog voltage control capabilities.
NOTES:
TARGET DISTANCE
The distance between the Turbodisk 2 and the target will aect the nish quality, penetration and eciency. Closer distances give wetter nishes and greater eciency, while greater distances give drier nishes. The recommended normal disk edge to target range is 12 inches minimum for optimum performance.

Turbodisk 2 - Maintenance
MAINTENANCE
GENERAL
Verify daily that the operating parameters have not varied dramatically. A sudden change or even a gradual decay in performance could be early indications of component failure.
No rmal ma intenance procedures should be established and recorded at the initial start-up. All maintenance schedules are subject to variation based on use. Periodically review these maintenance schedules as equipment ages and needs change.
CLEANING PROCEDURES
W A R N I N G
!
> Electrical shock and re hazards can exist during maintenance. The power supply must be turned o before entering the spray area. Spray booth fans should remain on while cleaning with solvents.
> Never touch the disk atomizer while it is spinning. The edge of the disk can easily cut into human skin, gloves or other materials. Be sure the disk atomizer has completely stopped spinning before attempting to touch it. Approximate time for the disk to stop spinning after turning o the drive air is about three minutes.
!
> Do not immerse the Turbodisk 2 assembly in solvent or other liquids. Turbine components will be damaged.
> Do not soak the disk in solvent longer than 24 hours.
C A U T I O N
Internal Fluid Path Cleaning
With the high voltage turned o and the disk spinning, ush cleaning solvent through the incoming paint line or through the solvent inlet line. If it is desired to clean just the face of the disk o, ush solvent through the solvent inlet. If a color change is required, ush the entire system. The spinning disk will atomize the solvent and clean out the disk passages. If equipped, trigger the dump valve to catch the wasted paint from the incoming line, then ush the disk with solvent after closing the dump valve.
NOTE
> Solvent ushing of the system (except during color change) should be done with the disk dismounted and with waste solvent collected in a grounded container.
In addition to the above Warning, which relates to potential safety hazards, the following information must be observed to prevent damage to the equipment.

LN-9240-02.1
Turbodisk 2 - Maintenance
External Atomizer Surface Cleaning
W A R N I N G
!
> To reduce the risk of re or explosion, OSHA and NFPA 33 require that solvents used for exterior cleaning, including disk cleaning and soaking, be nonammable (ash points higher than 100oF/37.8oC). Since electrostatic equipment is involved, these solvents should also be nonpolar. Examples of nonammable, nonpolar solvents for cleaning are: Amyl acetate, methyl amyl acetate, high ash naphtha and mineral spirits.
> Do not use conductive solvents such as MEK to clean the external surfaces of the Turbodisk 2.
> Never lower the Turbodisk 2 assembly into a drum for ushing or color changing.
Clean the disk by soaking in an appropriate solvent to loosen paint residue. Do not soak for more than a 24 hour period. Use a soft cloth to remove the paint from the surface and a soft bristle brush to remove paint from the well area. The splash plate may need to be removed to clean the paint well. The screws must be retorqued to 24 lbin after cleaning.
Reinstall the disk and torque the mounting nut to 50-60 lbin.
W A R N I N G
!
> Do not attempt to clean the disk edge while
it is rotating. Do not attempt to slow down or stop the disk by holding a rag or a gloved hand against the edge. This could cause physical harm and/or damage to the disk.
!
C A U T I O N
Disk Cleaning
Normally, the internal cleaning instructions will suce to clean the disk. If ushing the disk does not remove all the residue, the disk may be removed for hand cleaning. Unscrew mounting nut and remove the disk by using the supplied disk puller.
Inspection of the disk is required to determine if wear to the serrated edge or damage has occurred. Wear can cause a reduction in transfer eciency and excessive paint wrap on the atomizer fairing.
NOTE
> The turbine shaft must be held with a
7/16” open end wrench while using the disk puller.
W A R N I N G
!
> Do not use abrasive materials which will scratch or damage the disk. Cleaning pads such as Scotch-Brite® should not be used.
> Using an atomizer disk with paint buildup may cause an imbalance. This may result in bearing damage and turbine failure. This condition may also stress the disk when operating at high speeds.
> Before reinstalling the disk onto the shaft, check and clean the tapered mating surface for paint residue.
> Care must be taken when mounting the disk assembly to the motor shaft. The mounting nut should turn freely for several turns until it fully bottoms on the disk assembly.
> Do not hold disk edge during removal. This
could result in injury.
