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.
IT IS VERY IMPORTANT THAT ALL PERSONNEL USING THE EQUIPMENT
BECOME FAMILIAR WITH THIS SAFETY INFORMATION.
The following information is provided concerning various aspects of worker safety with
this equipment. Because some features of the system may be new to personnel using
the equipment, an attempt has been made to provide a fairly extensive background on
these issues as well as to reference, where feasible, further information or U.S.
Government Standards.
With care in installation and operation, coupled with adequate worker training, no unusual
safety problems should arise.
2.1. Ultraviolet Radiation
Ultraviolet radiation (UV), which is emitted during normal operation of AUV/LESCO
SPOTCURE systems, can be dangerous to the eyes and skin. All personnel within close
vicinity 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 if brought in direct contact at or near the focal point. Care
should be taken to avoid this.
The American Conference of Governmental and Industrial Hygienists (ACGIH) and the
National Institute for Occupational Safety and Health (NIOSH) published guidelines on
threshold exposure. These values are related to the different UV spectra and time of
exposure.
There is no present US government standard on worker exposure to UV light. However,
there is a NIOSH 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.

KMM1002P 7
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.
3.0. Components Description
3.1. Housing
The MK III housing is made of stainless steel, making the equipment suitable for clean
room operations and allowing for easy cleaning. The housing consists of 3 main sections:
1. Chassis - The vertical design allows for more efficient use of counter-top space. The
optical assembly is located in the upper compartment. The top cover is secured by
loosening four quarter-turn, captive, Phillips head fasteners. The power supply and all
the controls and accessories are located in the bottom housing.
2. Lamp Housing - The top cover is secured by four quarter-turn, captive Phillips head
fasteners. Removing it allows access to the bulb, reflector, and the IR filter
assemblies.
3. Bottom Cabinet – The bottom side cover is fastened by six Allen head screws.
Removing it allows access to the power supply for voltage setting. There are no
serviceable parts inside.
The housing compartment features a recessed rear panel with air vents on the top and
sides. These vents provide air access to the cooling fans even if the MK III is operated
while pushed all the way against a wall.

sensor and electrical lamp connections. The function of each component in the lamp
housing is described below.
Reflector
Lightguide
Receptacle
UV Bulb
UV Bulb Connector Block

KMM1002P 9
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. Maximum bulb life is obtained when the lamp operates without interruption, 24
hours a day.
Frequent ON-OFF operations shorten bulb life. The deterioration varies with duty cycle
(number of operating hours per start) and with electrode temperature at the time of start
(cold strike vs. hot or warm restrike), rendering it impossible to assign a conclusive value
to bulb life under intermittent operation.
As a general rule, it is recommended that if the unit is to be used again within the next
4 hours, it should be left ON with the shutter closed.
3.1.3. Bulb Connection
The black lead wire coming from the bulb and the red lead wire from the reflector holder
assembly correspond to the same colored sockets located in the reflector support block.
Please ensure the black lead wire runs through the access hole on the bottom of the
reflector holder as pictured below.
Bulb Connection
***CAUTION***
Do not touch the quartz (glass) portion of the bulb with bare hands or fingers.
Skin oils can cause premature lamp failure or explosion. If hand oils accidentally
contact the bulb, wipe clean with Isopropyl alcohol and lint free cloth.

KMM1002P 10
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. The bulb is optically aligned within the reflector. The precision
based bulb and reflector holder assembly allows for simple replacement of bulbs without
expensive or difficult re-alignment.

KMM1002P 11
3.2. Front Panel
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. The hour meter can be reset to zero by a push-
button switch located at the rear panel of the unit. After installing a new bulb (with the
power on) reset the hour meter using the push button switch located on the back panel.
3.2.2. Lightguide Receptacle
The Lightguide Receptacle is a precision mechanical assembly that aligns the bulb, bulb
reflector assembly and lightguide for optimal focal point location. It also supports the
shutter assembly, optical feedback sensor, lightguide safety switch and infrared filter.
The lightguide transmits UV energy most efficiently when it is straight. Bends in the
lightguide decrease UV transmission. For best results, keep the bend radius at 5" or
more. Bends tighter than 4" arm to arm (2" radius) may cause irreversible damage.
3.2.3. Automatic Shutter Timer
The timer, located in the lower chassis compartment, is mounted on the front panel so
that it is visible and can be set from the outside. Setting of the timer is done by pushing
four miniature thumb switches, each controlling one digit of a four-digit clock. The timer
can be set in .01-second increments for exposure time of .01 second to 99.99 seconds.

KMM1002P 12
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. The power supply also provides a 24 VDC source for the cooling fans and the
shutter solenoid.
3.2.5. Shutter Assembly
The shutter assembly is a positive open, spring return rotary solenoid connected to the
shutter plate for efficient control and safety of the shutter open cycle. The shutter is also
connected to an interlock switch located on the lightguide receptacle where the end of the
lightguide is inserted. This switch disables the shutter in the closed position to ensure that
there is no unintentional exposure if the lightguide is missing or improperly inserted into
the MK III.
3.2.6. Timer/Manual Selector Switch
The Timer/Manual toggle switch is located next to the bottom-cooling fan on the recessed
panel at the rear of the unit. In the "Timer" position, pressing the footswitch triggers the
timer and opens the shutter. The shutter automatically closes when the timer reaches the
preset duration. In the "Manual" position, the timer is inoperative and the shutter stays
open as long as the footswitch is pressed down or the signal is held on.
3.2.7. Footswitch
The remote footswitch is equipped with a 6-foot cable, which plugs into a receptacle at
the rear panel of the MK III. The footswitch is used to activate the timer when operated in
the Timed-Exposure mode, or the shutter when operated In the Manual operation mode.
** CAUTION **
Disconnect power from system or unplug system from wall or
VAC power source before connecting the footswitch adapter.
3.2.8. Power Cord
The MK III comes with a 6 foot, 3 prong 110V shielded power cord, which plugs into a
receptacle located at the rear panel. 220V power cords are available on request.

** WARNING **
For continued protection against risk of fire,
replace only with the same type and rating of fuse.
Input volts Fuse rating
100-120 4A T, 250 VAC, Slow Blow
220-250 2A T, 250 VAC, Slow Blow
3.3.3. IR Filter
The heat filter is located at the lamp-facing end of the lightguide socket, also called the
nosepiece. Accessible from the upper chassis compartment, it is mounted in a “cassette”
type filter holder and easily removable toward the side of the nosepiece assembly. Many
different types of filters are available, offering different radiation bands to fit specific
applications. The filter function is to screen out the unwanted radiation from the focused
light provided by the reflector, thus protecting the lightguide as well as the work surface
from excessive heat.
3.3.4. Optical Feedback Sensor (Optional)
The optical feedback sensor is located on the lightguide socket receptacle monitoring the
energy at the entrance of the light guide. This signal is sent to the control circuit of the
power supply, which internally monitors the intensity set point. The power supply will
make the power adjustments to maintain that intensity set point.
The sensor is specially designed to respond to the UV radiation band, allowing it to detect
minute differences in the output of the bulb, as well as the performance of the reflector
and the IR filter. Its response frequencies extend from the UVA to the UVB and UVC
bands, allowing it to run with all the IR filters available.
