� Relieve (bleed off) hydraulic and pneumatic pressure before adjusting orservicing pressurized systems or components. Disconnect, lock out,and tag switches before servicing electrical equipment.

� While operating manual spray guns, make sure you are grounded.Wear electrically conductive gloves or a grounding strap connected tothe gun handle or other true earth ground. Do not wear or carry metallicobjects such as jewelry or tools.

� If you receive even a slight electrical shock, shut down all electrical orelectrostatic equipment immediately. Do not restart the equipment untilthe problem has been identified and corrected.

� Obtain and read Material Safety Data Sheets (MSDS) for all materialsused. Follow the manufacturer’s instructions for safe handling and useof materials, and use recommended personal protection devices.

� Make sure the spray area is adequately ventilated.

� To prevent injury, be aware of less-obvious dangers in the workplacethat often cannot be completely eliminated, such as hot surfaces, sharpedges, energized electrical circuits, and moving parts that cannot beenclosed or otherwise guarded for practical reasons.

High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremelyhazardous. Always relieve fluid pressure before adjusting or servicing highpressure equipment. A jet of high-pressure fluid can cut like a knife andcause serious bodily injury, amputation, or death. Fluids penetrating theskin can also cause toxic poisoning.

If you suffer a fluid injection injury, seek medical care immediately. Ifpossible, provide a copy of the MSDS for the injected fluid to the health careprovider.



The National Spray Equipment Manufacturers Association has created awallet card that you should carry when you are operating high-pressurespray equipment. These cards are supplied with your equipment. Thefollowing is the text of this card:

WARNING: Any injury caused by high pressure liquid can be serious. Ifyou are injured or even suspect an injury:

� Go to an emergency room immediately.

� Tell the doctor that you suspect an injection injury.

� Show him this card

� Tell him what kind of material you were spraying

MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO PHYSICIAN

Injection in the skin is a serious traumatic injury. It is important to treat theinjury surgically as soon as possible. Do not delay treatment to researchtoxicity. Toxicity is a concern with some exotic coatings injected directly intothe bloodstream.

Consultation with a plastic surgeon or a reconstructive hand surgeon maybe advisable.

The seriousness of the wound depends on where the injury is on the body,whether the substance hit something on its way in and deflected causingmore damage, and many other variables including skin microflora residingin the paint or gun which are blasted into the wound. If the injected paintcontains acrylic latex and titanium dioxide that damage the tissue’sresistance to infection, bacterial growth will flourish. The treatment thatdoctors recommend for an injection injury to the hand includes immediatedecompression of the closed vascular compartments of the hand to releasethe underlying tissue distended by the injected paint, judicious wounddebridement, and immediate antibiotic treatment.

Fire Safety To avoid a fire or explosion, follow these instructions.

� Ground all conductive equipment. Use only grounded air and fluidhoses. Check equipment and workpiece grounding devices regularly.Resistance to ground must not exceed one megohm.

� Shut down all equipment immediately if you notice static sparking orarcing. Do not restart the equipment until the cause has been identifiedand corrected.

� Do not smoke, weld, grind, or use open flames where flammablematerials are being used or stored.

� Do not heat materials to temperatures above those recommended bythe manufacturer. Make sure heat monitoring and limiting devices areworking properly.

Fiber Optic Module4


Fire Safety (contd)

� Provide adequate ventilation to prevent dangerous concentrations ofvolatile particles or vapors. Refer to local codes or your material MSDSfor guidance.

� Do not disconnect live electrical circuits when working with flammablematerials. Shut off power at a disconnect switch first to preventsparking.

� Know where emergency stop buttons, shutoff valves, and fireextinguishers are located. If a fire starts in a spray booth, immediatelyshut off the spray system and exhaust fans.

� Shut off electrostatic power and ground the charging system beforeadjusting, cleaning, or repairing electrostatic equipment.

� Clean, maintain, test, and repair equipment according to the instructionsin your equipment documentation.

� Use only replacement parts that are designed for use with originalequipment. Contact your Nordson representative for parts informationand advice.

Halogenated Hydrocarbon Solvent Hazards Do not use halogenated hydrocarbon solvents in a pressurized system thatcontains aluminum components.

Figure 2 Fiber Optic Module Operation

1. Magnets2. Visible light transmitter

3. Fiber optic cable 4. Photoelectric sensor

The fiber optic module is connected to the rotary atomizer by an optional12 meter (40 ft) long fiber optic cable. The length of the cable allows themodule to be mounted outside the spray area in a non-hazardousenvironment.

One end of the fiber optic cable is connected to a ferrule secured by a setscrew to the rotary atomizer interface plate and the other end is connectedto the photoelectric sensor in the fiber optic module.

A visible light transmitter assembly is installed in the rotary atomizerinterface plate. The transmitter contains a coil and LED. Magnetsembedded in the turbine wheel generate a pulsating current in the coil asthey rotate past it. The LED converts the current into pulses of visible light.The fiber-optic cable transmits the pulses of light to the fiber-optic module.The light pulse is converted by the photoelectric sensor in the module intoa 0-15 Vdc square wave output.

For open-loop (manual) speed control, this output is used by a displaydevice such as the RPM Indicator to display turbine speed. The operatormanually adjusts air flow and pressure to control the turbine speed.

For closed-loop (automatic) speed control, this output is used by a PLCcontroller and voltage-to-pressure or current-to-pressure transducers andregulators to monitor and control turbine speed.



Installation WARNING: Allow only qualified personnel to perform the following tasks.Follow the safety instructions in this document and all other relateddocumentation.

WARNING: Relieve system pressure and remove and lock out allpneumatic, hydraulic, and electrostatic inputs before connecting the fiberoptic cable to the rotary atomizer.

CAUTION: Do not use solvents to clean the fiber-optic cable. Solvent willdamage the fiber-optic core. Use a clean, soft cloth to clean the cable.

Module Installation Use 1/4 inch fasteners to mount the module on a rigid, permanent mountingsurface in a non-hazardous environment.

This section contains troubleshooting procedures. These procedures coveronly the most common problems that you may encounter. If you cannotsolve the problem with the information given here, contact your localNordson representative for help.

Problem Possible Cause Corrective Action

1. RPM not displayed oris inaccurate

Wiring between the fiber opticmodule and receiving device

Check and repair loose connectionsor damaged wiring.

15 V not present Check wiring and the power sourceoutput. Repair or replace wiring orpower source.

2. Power source notfunctioning

Wiring between power source andfiber optic module

Check between GND and TB1-4 onthe fiber optic module terminal block.Voltage should toggle between 0 and15 Vdc as the cup spins.

Voltage is not toggling between15 V and 0 V

Replace the fiber optic module.

Corrective ActionPossible CauseProblem

3. LED lights in fiberoptic module do notilluminate

Fiber optic cable or visible lighttransmitter damaged, orphotoelectric sensor misadjustedor failed

Remove the cover from the fiber opticmodule.

With power applied, bearing air on,and turbine air off, slowly spin theatomizer turbine by hand. The redLED on the sensor should turn on(light sensed) and off as the cup isspun slowly.

The red LED on the bottom of thesensor will turn on and remain onwhen power is applied.

Remove the fiber optic cable from thefiber optic module.

Spin the cup by hand with bearing airon and the turbine off. Look into theend of the fiber optic cable as theturbine is spun by hand. If a blinkinglight is seen, adjust the sensor. If thesensor cannot be adjusted, replace it.

If a blinking light is not seen, removethe cable from the rotary atomizerand rotate the cup by hand whilelooking for a red blinking light fromthe visible light transmitter.

If a light is seen, replace the cable. Ifno light is seen, replace the visiblelight transmitter.

Repair Repair of the fiber optic module is limited to the removal and replacement ofthe photoelectric sensor. Refer to Parts for the sensor and the fiber opticcable kit part numbers and ordering information.
