2.1
Ultraviolet Radiation
Ultraviolet radiation (UV), which is emitted during normal operation of AUV/LESCO spot cure
systems, can be dangerous to the eyes and skin. All personnel within close proximity of
direct UV light should be required to wear goggles with UV certified lenses or remain behind
UV blocking light shielding. Personnel should also be prevented from allowing any skin
surface from coming within close proximity of the high intensity light output(s).
Additionally, it is never advisable to stare directly at any high intensity light source whether
visible or ultraviolet for prolonged periods unless precautions have been taken to reduce
both visible and ultraviolet light to safe levels. Discomfort from excessive eye exposure to UV
light typically occurs about six hours after exposure. Personnel who experience eye pain
after possible exposure to direct UV light should see a doctor immediately. Highly focused
radiation, whether UV or visible light, can ignite paper and similar combustible materials.
Care should be taken to avoid this.
There is no present US government standard on worker exposure to UV light. However,
there is a NIOSH (National Institute for Occupational Safety and Health) document, "Criteria
for a Recommended Standard - Occupational Exposure to Ultraviolet Radiation" (No. HSM
73-11009), and several useful publications are available from the Bureau of Radiological
Health of the Food and Drug Administration.

6.1.1 Cleaning
**WARNING**
Make sure the main power switch is turned off and
the power cord is unplugged before cleaning the unit.
To clean, unplug the unit and wipe down outer surfaces with a damp, clean cloth. If
necessary, use mild detergent, acetone, or alcohol. Let unit air dry before applying power.
**CAUTION**
Use of any other chemical may result in rust or tarnish to the surface, and void
the warranty.
KMD1060E
15
6.1.2 Air Filter Cleaning
The COOL CURE 365/ 390/ 395 has one exhaust cooling fan located at the rear panel and
one intake air hole, both equipped with a removable air filter. To remove the air filter, snap
off the flexible plastic fan cover. The air filter is easily removable from the fan opening. Wash
the filter with warm water and air dry. When dry, place the filter inside the plastic cover and
snap shut over fan.
6.1.3 Fuse Replacement
The external fuse is below the power-input receptacle on the rear panel. Remove power cord
and open the small drawer underneath the receptacle. Using a small screwdriver remove
the fuse and replace, then push the drawer shut. Insure that the replacement fuse has the
same rating as the blown fuse.
6.2
Optical Components
The optical components that need maintenance are the heat sink assembly and the light
guide.
6.2.1 Light guides
AUV/LESCO light guides are available in either “liquid-filled” (LF) or “fiber optic” (FO) types.
3.3.2.1.
Liquid-Filled Light guides
The standard light guide shipped with most AUV/LESCO SUPERSPOT cure products is a
1M x 5mm LF model. This device allows flexible delivery of high intensities of energy with
approximately 80% transmission efficiency in the UV “A” and visible ranges. LF light guides
come standard in 1M and 1.5M lengths, in single, bifurcated (dual outputs), and trifurcated (3
outputs) orientations. The light guide tips are available in 3mm, 5mm, or 8mm diameter
models. AUV/LESCO also offers a variety of custom light guides for special purposes.
These include special models optimized for high transmission in the UV “B” and UV “C”
range (230 to 390 nm). Custom lengths are also available upon request. Contact
AUV/LESCO for price and delivery of special products.
AUV/LESCO’s precision-built LF light guides are high quality optical instruments, but their
performance will degrade with exposure to UV energy. Under normal operating conditions,
the user can expect from 1 to 2 years of use from a LF light guide if cared for properly.
However, normal degradation will be greatly accelerated with aggressive radiation and/or
extreme heat levels. For a given dosage, it is well established that higher intensity for
shorter time periods is the preferred method for producing maximum cure strength for the
majority of applications. However, care must be taken to minimize very high intensity levels
for sustained periods of exposure time.
KMD1060E
16
The special IR reduction filter in AUV/LESCO SUPERSPOT cure systems must not be
removed if working with moderate to high levels of intensity and exposure time. If either of
these conditions occurs, the LF light guide may suffer irreparable damage or have its service
life reduced dramatically. Special duty AUV/LESCO FO light guides are available for
extreme intensity/dosage applications (contact factory at 1-800-615-3726).
Fiber Optic Light guides
AUV/LESCO fiber optic (FO) light guides are used for applications where long lengths, tight
clearances, or multiple outputs are required. FO light guides are available in almost endless
configurations for specialized applications. Popular standard products are Bi-, Tri-, and
Quad-furcated light guides, but AUV/LESCO FO light guides can be ordered with 10 or more
output ends arranged in circular, line, or random configurations.
All light guides can be damaged or suffer impaired light transmission if not used properly.
Minimize bending a light guide radically (i.e. – more than 90° over a 6” radius for a LF). Be
extremely careful not to scratch, mar or accidentally apply curable material to the guide end
tips. One may (and should) clean the quartz end tips with alcohol on a regular basis and
check transmission levels at least every 100 operating hours (more often if end tips are not
fixtured). Transmission losses can be easily determined by using an AUV/LESCO Quartz
Calibration Fixture and radiometer.
Refer to Troubleshooting Section “Low UV Output” for further details.
Light guide Maintenance
Your Fiber Optic Light Guide (FOLG) is designed to provide a long life of dependable and
consistent energy transmission. In order to sustain the high levels of throughput and extend
its useful life, the FOLG must be properly maintained.
Following are some general maintenance guidelines for your reference. If you need any
additional help or have further questions, please contact AUV/LESCO.
1. Inspect the FOLG regularly. A visual inspection of the light emitting ends will detect
most problems associated with buildup of residues or signs of deterioration. To inspect it,
use a bright incandescent LED. It is better to cover the opposite end to prevent back
illumination. The surface should look black and very shiny. If it looks dull, there is residue
on it and it should be cleaned.
2. Never use a sharp object to clean the fiber surfaces. Use only high-quality solvents. We
recommend using reagent free acetone. Do not use regular acetone as it may leave a
residue.
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. Do not use any solvents that can dilute epoxy adhesives. Use alcohol to clean
any deposits on the mono-coil surface.
KMD1060E
17
5. If the fiber surfaces cannot be cleaned or continue to release material, please return the
FOLG to AUV/LESCO for repair. It may be necessary to re-polish the surfaces or rebuild
the ends.
Following these general guidelines and proper preventive maintenance will give you the
expected long life of your FOLG. Please make sure you keep it clean and working properly
to benefit from its unmatched performance.

Pins #3 and #4 are the output of an electrical relay. The relay contacts are rated at 250VAC / 6
AMPS.
The relay contacts are in a NORMALY OPEN state (when the LED is not emitting light).
When the LED is emitting light, the relay contact will “CLOSE” and will have electrical continuity
through pin# 3 and #4.
You can connect a series load of up to 250VAC / 6 AMPS.
So the relay contact is “OPEN”, when no light is present. And “CLOSED” when light is present. (It’s
a simple SINGLE POLE SINGLE THROW SWITCH).

9.0 Troubleshooting
*** WARNING ***
Disconnect power and unplug from VAC source before troubleshooting.
*** CAUTION ***
PARTS MAY BE HOT. If unit was running allow time for cool down.
Exercise care when touching internal optical parts.
*** CAUTION ***
Before connecting the footswitch, disconnect the VAC power source from the
system.
Fault
Action
Unit Does Not Turn On
Check power availability at the selected power outlet.
Check that power cord is properly connected.
Check the fuse.
Check that the top cover is installed properly and is pressing
down on the safety interlock switch (top of rear panel).
Unit Blows Fuses
Check fuse for proper rating.
Perform visual examination of wiring harness. Any obvious
electrical shorts (disconnected terminals, etc.) touching the
chassis will cause the fuse to blow. Insulate, repair and
retest power supply. Replace power supply if necessary.
LED does not turn ON
Verify footswitch is plugged in and is in proper operation.
Turn power OFF.
Verify that the light guide is properly seated into the light
guide socket and that the ball plunger is in the detent
groove. The COOL CURE 365/365-HP/390/395/405 unit safety
system disallows LED operation if no light guide is sensed
by interlock switch within entrance fitting.
Fans Do Not Work
KMD1060E
Check for obstructions to the fan blades.
25
Low UV Output
Confirm LED is intact and functioning correctly by taking
radiometer reading with calibrated radiometer and
AUV/LESCO Quartz Test Fixture.
Verify that the light guide is properly seated completely into
the light guide socket (and that the ball plunger is in the
detent groove if applicable).
Verify that both ends of the light guide are clean. Clean
quartz surfaces with reagent free grade acetone using cotton
swab or equivalent means. If contamination cannot be
removed, please send the light guide back to AUV/LESCO
for re-polishing.
