  • Page 7: General Information

    1.1. Scope of Manual This manual provides the information necessary for operating and maintaining the AUV/LESCO SUPERSPOT MK III UV spot curing system. It contains descriptions of the major components, safety requirements and references to pertinent mechanical and electrical drawings.

  • Page 8: Safety

    2.0. Safety The AUV/LESCO UV SPOTCURE system has been designed to operate safely. Hundreds of AUV/LESCO UV curing systems are in operation in a wide variety of industrial environments worldwide without any worker safety problems or health hazards. However, this equipment can present worker safety problems if care is not taken to install and operate it correctly.

  • Page 9: Power Up

    2.2. Power up Always verify the correct voltage setting of the unit before applying power. Damage to the power supply can occur if wrong voltage is applied even momentarily. The UV bulb may also be affected. Verify the proper setting following Section 4.3 ** CAUTION ** Disconnect power from system or unplug system from wall or VAC power source before connecting the footswitch adapter.

  • Page 11: Uv Bulb

    3.1.2. UV Bulb The UV bulb is an efficient 100-watt short arc DC mercury vapor lamp. The lamp needs a high voltage ignition pulse in order to start. Once ignited, it requires one or two minutes to reach its operating voltage and current. This period is referred to as the "warm-up" time.

  • Page 12: Focusing Reflector

    3.1.4. Focusing Reflector The reflector is a high precision, first surface elliptical reflector used to gather and focus the highest concentration of energy from the bulb. 3.1.5. Bulb Reflector Module The Bulb Reflector Module is a detachable assembly consisting of the bulb, metal holder and an elliptical reflector.

    3.2. Front Panel Lightguide Port Receptacle Lamp on Window Optical Feedback Alarm Indicator Lamp Hour Meter Shutter Timer 3.2.1. Lamp Hour Meter The lamp hour meter mounted on the front panel records the cumulative number of lamp operating hours. The lamp hour meter is calibrated in 0.1-hour (6 minutes) increments, and displays from 0.1 to 9999.9 hours.

  • Page 14: Shutter Assembly

    The bi-level power supply is a solid state, high frequency switching DC supply suitable for operation on 110V and 220V ± 10%, 50/60 Hz. The power supply provides the high voltage pulse necessary to ignite the lamp and the operating voltage for continuous lamp operation.

    4.0. Installation/Start Up Before unpacking the system, inspect the shipping container for any damage such as broken corners, deformity, holes and/or tears. After unpacking the system, examine the equipment for any damage, i.e. unusual dents or rattling of components. Should there be any major damage immediately inform the shipping company and AUV/LESCO.

  • Page 18: Set Timer

    4.1.2. Set Timer Set the exposure timer to the desired exposure duration (0.01 to 99.99 sec.) by pushing the miniature thumb switches. If one intends to operate in the "Manual" mode, make sure the "Timer/Manual" switch is in the "Manual" position. See section 3.2.3. 4.1.3.

  • Page 19: Bulb Installation

    4.2. Bulb Installation ** WARNING ** Disconnect power and unplug unit from wall before installing or removing lamp or servicing unit. The following procedures will allow for proper operation of the MKIII system. 1. Using a Phillips screwdriver, loosen the four quick connects that are on the sides of the top cover.
  • Page 20 5. Plug the leads into the matching colored sockets and replace the housing. (NOTE: Be certain the black bulb lead wire is NOT pinched between the housing and retainer clips. Lead wire should be free of pressed contact from bulb to socket.) Re-attach the cover to the main unit.

It will close automatically when the set time has elapsed. If operating in the Timed Exposure mode, make sure that shutter selector switch is in the "Timer"...

  • Page 25: Calibration

    5.0. Calibration 5.1. Optical Feedback Operation Optical Feedback is designed to maintain constant exposure intensity over the lifetime of the bulb for tight process control. It automatically compensates for the normal decay of the bulb during its operating life, achieving a constant output to maintain uniform total energy per cure cycle.

  • Page 26: Optical Feedback Problems

    1. Close the housing after replacing the bulb, reflector, filter, and/or UV sensor. Turn the system on, attach the lightguide, and allow the lamp to warm up for 5 minutes. Insert +/- leads of DC voltmeter (not included) in the calibration test points located on rear panel.

  • Page 27: Maintenance

    6.0. Maintenance 6.1. Housing The MK III is a simple, rugged unit and does not require complicated routine maintenance. Routine maintenance consists of keeping the unit clean, periodical cleaning of air filters, and periodical UV output measurements to ensure that the unit performs optimally.

  • Page 29: Optical Components

    6.4. Optical Components The optical components are the reflector assembly, the shutter, the IR filter and the lightguide. 6.5. Reflector Assembly The reflector is a highly important component of the “optical train” since the light produced by the bulb must first be collected by the reflector. When the reflector is new, it has a very high efficiency, but with time and temperature, it slowly decays to lower levels.

    quote a variety of custom guides for special purposes. These include special models optimized for high transmission in the UV “B” and UV “C” range (230 to 390 nm). Contact AUV/LESCO factory for price and delivery of special products. AUV/LESCO’s precision-built LF lightguides are high quality optical instruments, but their performance will naturally degrade with time.

    3. Use a clean Q-tip or Clean-wipe to scrub the surface when applying the solvent. Make sure no material “bleeds” from the surface, as this is an indication that there has been mechanical damage. 4. Be careful not to expose the mono-coil jacket (black flexible tubing) surface to the acetone.
