UVCS LED Light-Curing Conveyor Systems User Guide
CAUTION! Always wear protective goggles or face shield when working near UV light. Never
look directly at light!
WARNING! Always observe safety requirements! Do not open the cover of the LED Array or
Power Supply. There are no user serviceable parts inside.
Specific Safety Considerations
Dymax UVCS LED light-curing conveyor systems are designed to maximize operator safety and minimize
exposure to light-curing energy. To use the unit safely, it must be set up and operated in accordance with the
instructions in this user guide. Please also read and understand the safety considerations unique to lightcuring systems as described below.
Safety Symbol Index
The following symbols are displayed on the curing system. Please see below for their meanings.
Refer to Manual
Warning!
Eye Protection Required
Warning! UV Light Hazard
Electrostatic Sensitive Device
WARNING! Looking directly at the UV light emitted by an LED flood array can result in eye
injury. To prevent eye injury, never look directly at the high-intensity light and always wear
protective goggles (provided).
Dymax Light-Curing System Safety Considerations
Operators must understand these three concepts to use the LED light source safely: light exposure, hightemperature surfaces, and bright, visible light. Each is described below.
Light Exposure
The BlueWave® LED Flood’s PrimeCure® and RediCure® models emit energy in the UVA portion of the
spectrum while the VisiCure® model emits energy in the visible portion of the spectrum. UVA light is generally
considered the safest of the three UV ranges: UVA, UVB, and UVC. Although OSHA does not currently regulate
visible or ultraviolet-light exposure in the workplace, the American Conference of Governmental Industrial
Hygienists (ACGIH) does recommend Threshold Limit Values (TLV’s) for ultraviolet light.
6
UVCS LED Light-Curing Conveyor Systems User Guide
Figure 1. Light Spectrum
The strictest interpretation of the TLV (over the UVA range) for workers’ eyes and skin is 1 mW/cm2 (intensity),
continuous exposure. Unless workers are placing bare hands into the curing area, it is unusual to exceed these
limits. To put 1 mW/cm2 limit into perspective, cloudless summer days in Connecticut regularly exceed
3 mW/cm2 of UVA light and also include the more dangerous UVB light (primarily responsible for suntans, sun
burns, and skin cancer) as well.
Checking the Workstation
The human eye cannot detect “pure” UV light, only visible light. A radiometer should be used to measure stray
UV light to confirm the safety of a UV light-curing process. A workstation that exposes an operator to more
than 1 mW/cm2 of UVA continuously should be redesigned.
Protecting Operators
Light-curing technology can be a regulatory compliant, “worker-friendly” manufacturing process when the
proper safety equipment and operator training is utilized. There are two ways to protect operators from UV
exposure: shield the operator and/or shield the source.
Shield the Operator
UV-Blocking Eye Protection - UV-blocking eye protection is recommended when operating UV light-curing
systems. Both clear and tinted UV-blocking eye protection is available from Dymax.
UV-Blocking Skin Protection
Where the potential exists for UV exposure upon skin, opaque, UV-blocking clothing, gloves, and full-face
shields are recommended.
Shield the Source of UV
Any substrate that blocks UV light can be used as a shield to protect workers from stray UV light. The following
materials can be used to create simple shielding structures:
Rigid Plastic Film — Transparent or translucent/UV-blocking plastics (typically polycarbonate or acrylic) are
commonly used to create shielding where some level of transparency is also desired.
7
UVCS LED Light-Curing Conveyor Systems User Guide
Flexible Film — Translucent UV-blocking, flexible urethane films can be used to quickly create workstation
shielding. This UV-blocking, flexible urethane film is available from Dymax, call for assistance.
High-Temperature Surfaces
Surfaces exposed to high-intensity curing lights will rise in temperature. The intensity, distance, exposure
time, cooling fans, and the type/color of the surface can all affect the actual surface temperature. In some
cases, exposed surfaces can reach temperatures capable of producing a burn or causing damage to a
substrate. In these cases, care must be taken to ensure either a more moderate surface temperature or
appropriate protection/training for operators. No infrared radiation is produced by these LED systems, so
surface temperatures will be lower than with conventional lamp systems. Empirical testing should be used to
verify the exact temperature rise in each application.
Bright, Visible Light
The bright, visible light energy emitted by curing systems can cause eyestrain if proper eye protection or
shielding is not used. The proper use of tinted eye protection and/or opaque/tinted shielding can be utilized to
reduce eyestrain and address this concern.
Summary
UV-light sources can be more “worker friendly” than many commonly accepted industrial processes, provided
the potential concerns are addressed. Both the lower working temperature and lack of spurious frequency
transmission that this system produces make it even more user friendly. Contact your Dymax representative
for information regarding the proper use of Dymax light-curing systems.
Product Overview
Description of UVCS LED Light-Curing Conveyors
Dymax UVCS LED light-curing conveyor systems use high-intensity light sources for fast curing of light-curable
materials. UVCS bench-top conveyors can be outfitted with BlueWave® LED flood systems available in one of
three different wavelengths (365 nm, 385 nm, or 405 nm). The flood system consists of two main components:
an LED flood array and a power supply that contains the user interface. Only one LED flood array can be
connected to a power supply at a time via the interconnect cable. The power supply is designed to be
interchangeable and can be used with any of the three different wavelength LED flood arrays. Up to four LED
flood arrays can be mounted on the conveyor.
BlueWave® LED flood systems feature an intensity adjustment, allowing the output intensity level to be
adjusted from 10 to 100% to meet process and adhesive requirements. LED technology within the BlueWave®
LED Flood System allows for instant on/off activation without the need for a warm-up period, and is also rated
for continuous operation. A switch on the conveyor is provided to keep the LED array always active.
Fans in the LED flood power supply and array provide cooling and must not be covered or blocked. Fan Filters
must be maintained regularly to ensure reliable operation. Thermal sensors in the LED flood power supply and
array shut the unit down to protect the components if the internal temperature exceeds maximum limits.
Please refer to the BlueWave® LED Flood System User Guide for further description and explanation.

UVCS LED Light-Curing Conveyor Systems User Guide
WARNING! If you block the air flow from the LED flood array or the power supply vents,
equipment damage and malfunction can result. To prevent damage and malfunction, ensure 1"
[2.54 cm] of clearance is provided around the power supply and at least 6" [15.24 cm] of clearance
is provided around the cooling fan inlets to allow the free flow of air.
All UVCS conveyors have adjustable belt speeds and lamp-to-belt distance to address a variety of application
requirements. Standard height clearance is 4 inches; optional risers increase clearance to either 6 or 10 inches.
When combined, the UVCS conveyors’ consistent intensity, fast curing, and adjustable line speeds create an
optimized light-curing process that enables high throughput.
