Introduction This manual is designed to be used, not set aside until problems occur. The following list of chapters and appendixes describes where to find information in this manual. • This Introduction provides a brief description of the total system, and system components. It also contains the Fusion UV Systems warranty policy and shipping instructions for returning equipment.
• Appendix C, “Outline Drawings,” contains drawings that provide overview details for general reference for Fusion UV Systems products. These drawings are not to be used in designing an installation; contact Fusion directly for current specifications. • Appendix D, “Lamp System Maintenance Log,” contains an example of a Fusion UV Systems form to use for tracking lamp system maintenance.
DANGER: Danger indications identify conditions where death or permanent injury to personnel can occur if proper procedures and precautions are not followed. Icon Usage Several icons are used throughout the documentation to identify the types of hazardous resources or technologies used when working with a particular aspect of the system. Table 1, “Icons,” lists these and their definitions.
Table 1. Icons (continued) Icon Definition CAUTION: Ultraviolet Radiation This icon identifies instances where damaging levels of ultraviolet radiation may be present. Adequate shielding around the equipment and region must be provided, and personnel should be required to wear goggles with UV certified lenses. All personnel within ten feet of the lamp should wear gloves and long sleeves to protect their hands and arms, and ensure that their legs are covered.
Table 1. Icons (continued) Icon Definition Protective Conductor Terminal Earth (ground) Terminal Three Phase Alternating Current System Description The Fusion Ultraviolet Lamp System has been designed specifically for applications involving the industrial curing of inks and coatings and may be used effectively for a wide variety of applications. An ultraviolet (UV) lamp system for industrial curing must generate extremely intense radiation in the 200-400 nanometer region.
Figure 1. F300S/F300SQ Lamp System The F300S/F300SQ Fusion UV Lamp System (Figure 1) is modular, consisting of independent 6-inch (15.2 cm) lamp units and corresponding modular power supplies. Two lamps can be placed end-to-end to form a 12-inch (30.5 cm) lamp system or can be placed in a continuous array to form lamps of 18-inch (45.7 cm), etc. This is possible because the illumination of the lamp is a full 6".
Electrical inputs to the lamp module are provided by a high voltage/control cable with a quick-connect fitting which supplies power for the magnetron, filament transformer and the interlock circuitry.
Cooling Proper operation of the lamp requires adequate cooling of the magnetron and the bulb. (See Appendix C, page 129, for irradiator cooling requirements.) Cooling air from a blower goes through the magnetron cooling fins and into the lamp housing. At this point, the airflow splits into two paths: one path exhausts through the irradiator housing vent holes, and the rest of the air flows into the cavity through cooling holes in the reflector. This airflow cools the bulb and exhausts through the RF screen.
The following table lists the various irradiator models manufactured by Fusion UV Systems, and describes their high-level differences. Table 2.
Mounting The lamps can be mounted over a moving substrate or web, supported by the bottom rails. The lamps should be mounted so that the rails sit 53 mm (2.1") above the surface to be cured. This allows the elliptical reflector to focus the most intense strip of light very near the substrate. Power Supply Each lamp system has its own power supply to house the high voltage circuits necessary to energize the magnetron, as well as all control and interlock electronics, and the built-in cooling fan.
Figure 4. P300M Front Panel Warranty Policy Items manufactured by Fusion UV Systems Incorporated are warranted (under normal and proper use) to be free from defects in material and workmanship. Fusion UV Systems will repair or replace, at its option, any defective parts when returned to Fusion by the purchaser, transportation paid. See the Terms & Conditions included with your sales order for the length of the warranty period.
NOTE: Any repairs or alterations, including the use of non-Fusion UV Systems (Fusion) parts, made by the user of this product without Fusion UV Systems’ prior written consent shall void all warranties provided by Fusion UV Systems and such warranties shall cease to be in effect. No allowance will be granted for such repairs or alterations.
Irradiators Irradiators should be returned in their original packaging. If this is not available, lamps must be double boxed, as follows: The lamp is to be placed in an inner box, using cardboard fills to assure a snug fit. The RF screen should be protected by taping a piece of cardboard over it. The inner box should then be placed in an outer box that provides about a two-inch clearance on all sides.
F300S/F300SQ Ultraviolet Lamp System
Chapter 1. Safety Fusion UV Systems’ Ultraviolet (UV) Lamp Systems have been designed to operate safely. Many systems are in production in a wide variety of industrial environments without any problems of worker safety or health hazards. However, like most industrial equipment, this equipment can present worker safety problems if care is not taken to install, operate, and maintain it correctly.
Ultraviolet Radiation Ultraviolet radiation which is emitted during normal operation of the Fusion Ultraviolet Lamp System can be dangerous to the eyes and skin of personnel. Adequate shielding around the system and the region to be irradiated must be provided. If unsafe levels of light are allowed to escape during operation, then all personnel in the vicinity of the lamps should be required to wear goggles with UV certified lenses.
Personnel Effects of Microwave Radiation OSHA (U.S. Department of Labor, Occupational Safety, and Health Administration Standard 29CFR 1910.97) and ANSI (American National Standards Institute Standard C95.1-1999) are the only major national organizations with voluntary guidelines for safe limits of occupational microwave radiation exposure. The ANSI recommendation is the more stringent of the two guidelines.
Ozone Ozone is a gaseous form of oxygen which is formed by ultraviolet light. It has a characteristic pungent odor to which most people are quite sensitive (people can typically detect concentrations of several parts per hundred million). At high concentrations it can cause discomfort or at sufficiently high levels be dangerous. The Fusion UV Lamp System makes less ozone than a conventional arc lamp.
High Voltage Insulated electrical cables carry power at 3900 Volts from the power supply to the lamp. These voltages can be dangerous, so some precautions should be taken in both the location and protection of these lines. High voltages are exposed within the power supply chassis, which should never be operated without its cover. DANGER: Never touch the power supply/lamp cable connections while the system is ON or in STANDBY.
F300S/F300SQ Ultraviolet Lamp System
Chapter 2. Mechanical Installation Mechanical Installation Checklist Before operating the ultraviolet lamp system for the first time, be sure the following procedures have been completed. Table 3.
Preliminary unpacking and inspection should be completed immediately on receipt of equipment to allow time for repair or replacement if necessary prior to installing the equipment. The P300M/P300MQ power supplies are shipped with six large Phillips head screws holding the cover to the chassis. There are three screws located on each side. The P300MT power supply is shipped with four large Phillips head screws holding the cover to the chassis. There are two screws located on each side of the P300MT.
Irradiator Mounting The irradiator mounting structure must also provide UV shielding and adequate venting for the cooling air. This is described on the following pages. Each user will normally design the mounting structure to suit the particular application, and the user is responsible for providing the required shielding and ventilation. (Irradiator dimensions are shown in Appendix C, “Outline Drawings” and detailed in the Appendix A, “Specifications”.
Lamps Mounted in Opposing Configuration IMPORTANT: If two lamps are to be mounted opposing each other (as shown in Figure 6 on page 34), lamp performance and operation may be impaired. Contact Fusion UV Systems Technical service department for consultation. Figure 6. Lamps in Opposing Configuration UV Light Shielding Adequate light shielding must be provided for each irradiator in the system.
The louvers which allow the flow of cooling air away from the irradiator must be of a light shielding design. (For more information on safety considerations, see Chapter 1, “Safety.”) RF Detector Mounting Figure 7 illustrates the proper mounting of the RF Detector. Figure 7. Fusion UV Systems RF Detector RF-1 One RF detection device must be installed for each light shield. The antenna should point toward the irradiator screen, which is the potential source of RF leakage.
Remote Blowers An optional remote blower package is available from Fusion UV Systems. The package includes an air distribution plenum (for multi-lamp systems), inlet filter box, and flexible hoses or ducts for cooling the system. The blower delivers 2.8 m3 /min (100 cfm) of air to each irradiator inlet at 695 Pa (2.8" H2O). See Chapter 6, “Maintenance” for information on the measurement procedure.

Figure 12. F300/F300SQ Single-unit Installation Programming Select one unit as the Master. Set S1-1, 1-2, 1-3, and 1-5 of this unit to “YES.” For programming switch S1 setting definitions, see Figure 11. Irradiator Cable H340 Connections Non-blower version cable H340 connects to J103 and J104 on the power supply; and to J10 on the irradiator. All connectors are labeled, and keyed so they cannot be inadvertently interchanged.
Input/Output Connections The P300M/P300MQ/P300MT has three customer use interlock inputs. A fault condition on any of these inputs will cause the system to shut down; the fault must be corrected before the system can be restarted. There must be one RF detector per system. The remaining interlock inputs are optional. The system blower and external interlock inputs in the P105A connector must be jumpered if these inputs are not used.
NOTE: A dry contact (such as a relay contact or a PLC containing a relay contact) with gold contact material should be used to drive the remote inputs. The cable length to the dry contact should be no more than 6 meters. Shielded cable should be used to minimize possible electrical interference. In a multi-lamp system, connections are made to the Master power supply. If there is a requirement for clearing faults remotely, a Remote Reset switch must be used. Table 6.

Programming Refer to Figure 11 for programming switch S1 settings and set programming switches of each power supply as follows: 1. Select one unit as the Master. Set S1-1, 1-2, 1-3 and 1-5 of this unit to YES. 2. Set S1-1, 1-2, 1-3, and 1-5 of all slaves to NO. 3. To shut down all units in case of a single-unit fault, set S1-4 on all units to YES (For a detailed explanation of unit faults, see Chapter 4, “Operation.
Power Source CAUTION: Measure the main single-phase voltage of your plant facilities to ensure that it conforms to the factory-wired operating voltage specified on the equipment label (rear panel of power supply). Available line voltage should be within 10% of the nominal operating voltage. Fusion UV equipment must be connected in accordance with local wiring codes. Use applicable standards for wire sizes, fuse sizes, and disconnect box locations.
North American Applications: 3x12 AWG UL listed International Applications: 3x2.5 mm2 Harmonized, VDE Both cable types should have minimum ratings of 16A, 300V, 0-60 °C. Refer to Table 11 on page 57 in Chapter 4, “Operation,” for the leg currents for each power supply/voltage combination. Frequency Tapping of HV Capacitors If it becomes necessary to configure the system for a line frequency other than that delivered, the following steps should be followed: 1.

Should these specifications change, or if a transformer is replaced, the transformer should be tapped as follows: Table 10.
F300S Relay Coil Resistor Assembly Installation The relay coil resistor assembly must be used if the line voltage and frequency used with a P300M/P300MQ/P300MT power supply is 230-240 VAC at 50 Hz (nominal voltage). These resistor assemblies prevent the premature failure of the relay coils in high line voltage environments. There are two coil resistor assemblies available in a retrofit kit (See Appendix E, “Replacement Parts”).

Chapter 4. Operation WARNING: Before operating the system, the operator must become familiar with the operating safety information presented in Chapter 1, “Safety”. System Operation Controls The lamp system is operated from the controls on the front of the power supply. NOTE: Ambient system operating temperature is 0 to 45°C. Lamp Control At STANDBY, power (115 VAC) is applied to the magnetron filaments without energizing the bulb. All interlocks and controls will continue to operate in STANDBY.
• Bulb producing insufficient output to activate the photocell For proper initial ignition, the recommended “MINIMUM LAMP ON” time required for this system is “ten (10) seconds” at normal air pressure (3.5 inches w.c.) and full power operation (100% power level). As previously mentioned, a “LAMP OUT” fault can occur when the bulb does not reach sufficient output to activate the sensing photocell.
3. Press the LAMP ON switch: the green LAMP ON indicator blinks, then stays lit. 4. Check the line currents. The line currents should conform to the values in Table 11. Table 11. P300M/P300MQ/P300MT Current Requirements System Line Voltage Single Phase Line Currents (A) with K300M Modular Blower without K300M Modular Blower 200 15 14.5 208 14 13.5 220 14 13 230 13.5 13 240 13.5 12 5. Check RF detector and customer use interlocks as described in Chapter 5, “Troubleshooting.
4. The LAMP CONTROL switches on the Master may now be used to activate all units in the system at the same time. NOTE: LAMP CONTROL flashers of slaves will follow LAMP CONTROL on Master. Resetting the System After a Fault If a fault occurs in the system, press the LAMP OFF/RESET switch on the Master, or cycle the remote LAMP OFF/RESET switch, then press the Master LAMP ON switch to reset the system.
NOTE: Times indicated are approximate and will vary. The exact interval is determined by conditions within the system. If additional RF detectors are connected to slaves, an RF fault in one of these slaves will automatically be interpreted as a system fault shutting down the entire system. In a Master/Slave system, the Slave units must be switched to STANDBY or ON before Master power supply is switched from OFF to STANDBY. Table 12.
2. Turn the Master POWER switch ON and press the LAMP ON switch. 3. The system will now operate from remote switches. Remote switch functions are virtually the same as front panel switch functions. Table 13. Remote Switch Functions Lamp Status Equivalent Panel Control Remote Switch Switch Open Switch Closed Lamp ON Lamp ON Standby Lamp ON Lamp RESET LAMP OFF/RESET Default to lowest state LAMP OFF/RESET Operation with Remote Controls Table 14.
The QRO consists of a high-voltage, low-current power supply section located in the P300MQ power supply that allows the magnetron in the irradiator to maintain an ignited bulb at a very low input power level (approximately 10%) and a very low UV output level (less than 1%). This feature is intended for use in processes that require occasional periods of decreased UV output, or in the event of a short duration process interruption.

Chapter 5. Troubleshooting DANGER: High Voltage -- Use extreme caution at all times when troubleshooting the power supply. Line voltages are present even when the lamp control switch is set to STANDBY. Do not measure any voltages not specified in the troubleshooting procedures: dangerously high voltages exist in the power supply. Do not touch power supply/irradiator cable connectors while the system is on. High voltages are present in the connector.
Safety Interlock Tests The fault indicators, RF detector, and external interlocks should be tested at regular intervals to assure safe operation of the UV system. 1. With the power supply chassis inserted into the cover and single-phase power applied, depress the IND TEST button on each power supply. All LED indicators should light. 2. Turn all POWER control switches to ON. (No UV light is being produced by the bulb.) Press the STANDBY switches of all units. 3.
Table 15. Unit Faults (continued) Indicator PWR ERROR Description Improper operation of magnetron: either no magnetron anode current 2-4 seconds after high voltage is applied, or the presence of high voltage when the Lamp system is in OFF or STANDBY. CAUTION: If a PWR ERROR fault is indicated, press the LAMP OFF/RESET switch immediately. To prevent magnetron damage, single-phase power should be disconnected (see PWR ERROR fault). PS TEMP The power supply is overheating.
Table 18, “Troubleshooting/Fault Diagnosis,” on page 69 covers miscellaneous faults and malfunctions. NOTE: The control card may be responsible for any of the fault conditions described following. If the fault cannot be determined after investigating all possible causes listed, check the control card for damage or improperly secured connectors. Return malfunctioning control cards to Fusion UV Systems.

Chapter 6. Maintenance This chapter provides maintenance procedures for the I300M irradiator, the I310M/311M Irradiator, the P300MT power supply, and the K300 modular blower. I300M Irradiator Bulb, Screen, and Reflector Maintenance Cleaning Guidelines At least every 500 hours of operation, the irradiator should be removed from the light shield, and the screen, lamp bulb, and reflector inspected carefully. Clean as needed.
If cleaning reflectors while assembled in the irradiator, drying with compressed air is NOT recommended because particles or residues can be driven into spaces between components and into optical sensing elements. Screen Cleaning Screens may be cleaned with the same cleaners cited previously, soaking if necessary, brushing lightly and rinsing well. Take care not to damage the gaskets or the fine screen wires.
1. Refer to Figure 19. Loosen the four M3 screen retaining screws three turns each. Repeat, this time removing screws. Grasp the screen frame by both ends, taking care not to twist or bend the screen itself, and remove screen assembly. 2. To replace existing screen or install a new one, place the screen assembly in position. 3. Apply pressure to the frame only and press firmly into place. Install the four screws alternately, working from side to side. Tighten each to a snug position; finally tighten to 0.
CAUTION: Do not apply bending force to the lamp bulb. Do not touch the bulb with bare fingers or allow it to contact dirty or greasy surfaces. Contaminants can be burned into the quartz envelope, causing premature bulb failure. 3. Clean any deposits from the surface of the bulb (see “Cleaning Guidelines” on page 79). Retaining hole Figure 21. Removing or Replacing the Bulb 4.
3. Referring to Figure 23, remove and discard the two end reflectors and the gaskets underneath. If evidence of arcing is present, clean the gasket grooves with emery cloth to remove all oxide. 4. Insert both end reflectors, ensuring that they both seat fully and evenly. The replacement end reflectors must be installed before installing the new bulb and reflectors and the new RF Gasket. 5. Install the two pre-cut (long) RF gaskets into the grooves for the end reflectors.
7. Align the reflector squarely over the opening. With gentle pressure and a rocking motion, slide the reflector down in place. It should not bind against the end reflectors as it goes into place. As a final motion, grasp the sides of the reflector and gently force them together a small amount, then settle the reflector down over the mounting surfaces (Figure 23). Start the six flat head screws in the reflector but do not tighten.
CAUTION: Do not use the flathead screws to pull the reflector into place. Excessive pull on these screws will deform the reflector face at its bend radius or loosen its rivets. This would result in a failure of the screen assembly to seat properly and subsequent damage to the screen gaskets. Figure 25. Correct Reflector Alignment (I300M) 8. When the reflector is properly installed, the face should be flush and even with the outer face of the two end reflectors as shown in Figure 25. 9.
11. Replace the screen assembly. After replacing the screen assembly, refer to Figure 26; hand-tighten the four M3 screws as shown until snug. Tighten them in sequence to 0.9 N-m (8 inch-lbs.) using a torque-controlled screwdriver. Repeat tightening the fasteners according to the sequence and torque specified. Figure 26.

Air Pressure Switch Replacement 1. Remove the irradiator cover. 2. Pull the silicone tubing off the low pressure port of the switch. 3. Disconnect the two electrical leads from the switch. 4. Reach inside the air distribution plenum and remove the short length of silicone tubing which secures the pressure switch to the plenum wall. 5.
Bulb Cleaning Handle bulbs with a lint-free cloth or tissue taking care not to leave fingerprints. Baked-on material can be removed from bulbs with a mild abrasive cleaner such as Soft Scrub®, followed by a thorough rinse with water. If alcohol is allowed, do a final wipe with alcohol. Harsh abrasives and steel wool should never be used on bulbs. Reflector Cleaning If the reflector surface is dull or discolored, it should be cleaned. Abrasives should never be used on reflectors.
Screen Assembly Removal/Replacement CAUTION: In handling the irradiator or screen assembly, try to avoid all direct contact with the screen, as it punctures easily. Do not apply pressure to the screen. 1. Refer to Figure 31. Loosen the four M3 screen retaining screws, using three turns each. Repeat, this time removing screws. Grasp the screen frame by both ends, taking care not to twist or bend the screen itself, and remove the screen assembly. 2.
CAUTION: Do not apply bending force to lamp bulb. Do not touch the bulb with bare fingers or allow it to contact dirty or greasy surfaces. Contaminants can be burned into the quartz envelope, causing premature bulb failure. Retaining hole Figure 32. Removing or Replacing the Bulb (I310M/I311M) 3. Clean any deposits from the surface of the bulb (see “Cleaning Guidelines” on page 91). 4.
2. Remove the six flat head screws and lift the reflector out. Examine the cross-guide gaskets for wear and/or arcing; replace if there is any sign of either. Replace as described in “Replacing the RF Gasket Assembly” on page 99. 3. Refer to Figure 33 on page 95, and remove and discard the two end reflectors and the gaskets underneath. If evidence of arcing is present (dark or burned spots), clean the gasket grooves with emery cloth to remove all oxide. Figure 33.

Reconnect the electrical leads. 7.
Test Point Voltages WARNING: Before taking magnetron current readings, turn the unit off. Check resistance between “MAG CURRENT” test points. Reading should be approximately 40K Ohms. If this value is not correct, do not attempt current reading. Damage could result to the meter or personnel injury could result. Contact Fusion UV Systems Customer Service if 40K Ohms reading is not obtained. After checking resistance, be sure to switch the meter to correct setting for DC voltage reading. Table 19.
Diode Test An ohmmeter can be used to check for a shorted or open capacitor. (Isolate the component before making continuity tests.) WARNING: Disconnect all power sources before servicing high voltage components. Ohmmeters having less than a 6V battery can give erroneous indications of high resistance in both directions when testing these high voltage diodes. 1. With an insulated screwdriver, short the capacitor terminals to each other to assure discharge of capacitor voltage. 2.
Figure 44.
Capacitor Test CAUTION: An ohmmeter can be used to check for a shorted or open capacitor. (Isolate the component before performing continuity tests.) WARNING: Disconnect all power sources before servicing high voltage components. The ohmmeter should have a minimum 6V battery, and should be set on the high resistance scale. 1. Remove all power, discharge the capacitor, and disconnect all leads from the capacitor terminals. 2.
1. Disconnect all power, discharge the high voltage capacitors, and disconnect all leads from the transformer terminals. 2. Unbolt the transformer from the power supply chassis. 3. To replace the transformer, reverse the steps, being certain that terminals are in the correct locations. Refer to Table 20, “Transformer Terminal Orientation,” on page 112 that follows. CAUTION: Transformers must be securely mounted to the chassis to provide adequate transformer grounding.

Appendix F. Ignitor Bulb NOTE: This appendix applies to lamps manufactured before July 1, 2002. Ignitor The ignitor bulb is designed to provide positive instant ignition of the main bulb. As shown in Figure 58, the ignitor is a UV bulb with a probe which projects into the waveguide. The instant the magnetron is energized, the probe intercepts enough energy to ionize the ignitor bulb, creating a small amount of UV radiation which reliably causes ignition in the main bulb.
Ignitor Bulb Table 37. Routine Operations Associated with Ignitor Bulb (Refer to Table 12 on page 59 for other operational information.
Ignitor Bulb Removal/Replacement 2. Remove the irradiator housing as described in Chapter 6, “Maintenance”. 3. Pull the defective bulb out and push the new bulb into the mounting clip. make sure the stem of the bulb fits into the waveguide so that the outer Teflon sleeve on the antenna wire is against the casting (see Figure 58).
