Safety
WARNING! If you use a Dymax light-curing conveyor system without first reading and understanding the
information in this user guide, injury can result from exposure to UV light. To reduce the risk of injury, read and ensure
you understand the information in this user guide before assembling and operating the system.
General Safety Considerations
All users of Dymax light-curing conveyor systems should read and understand this user guide before assembling and using the
system.
To learn about the safe handling and use of light-curable formulations, obtain and read the SDS for each product. Dymax includes
an SDS with each adhesive sold. In addition, fluid product SDS can be requested on the Dymax website.
CAUTION! Always wear protective goggles or face shield when working near UV light. Both the front and the rear
of the unit may emit UV light. Never look directly at light!
WARNING! Always observe safety requirements!
Specific Safety Considerations
Dymax 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 light-curing systems as described below.

DYMAX.COM W I D E C U R E ®CONVEY O R U S E R G U IDE |5
WARNING! Looking directly at the UV light emitted by a light-curing conveyor can result in eye injury. To prevent eye
injury, never look directly at the high-intensity light and always wear protective goggles (provided).
CAUTION! This unit generates ozone during operation. Adequate ventilation should be provided or the unit should
exhaust to outside.
There is a risk of electrical shock if the control cabinet is opened during installation and operation. A certified electrician
should install the proper connections to the system.
The sides of the unit are warm to the touch when the unit is in operation.
Dymax Light-Curing System Safety Considerations
Operators must understand these three concepts to use the light source safely: UV exposure, high-temperature surfaces, ozone,
and bright, visible light. Each is described below.
UV Exposure
Standard Dymax UV light-curing systems and bulbs have been designed to primarily emit UVA light (Figure 1). UVA light is
generally considered the safest of the three UV ranges: UVA, UVB, and UVC. Although OSHA does not currently regulate
ultraviolet light exposure in the workplace, the American Conference of Governmental Industrial Hygienists (ACGIH) does
recommend Threshold Limit Values (TLVs) for ultraviolet light.
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/cm2limit
into perspective, cloudless summer days in Connecticut regularly exceed
3 mW/cm2of UVA light and also include the more dangerous UVB light (primarily responsible for sun tans, 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/cm2of 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:
Sheet Metal —Aluminum, steel, stainless steel, etc. Sheet metal should be coated black or black anodized to minimize reflection
of UV and visible light toward operators.
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.
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.
Ozone
Standard Dymax bulbs (UVA type) generate an insignificant amount of UVC and therefore essentially no ozone. Some UV light-
curing systems, like those used to cure UV inks, emit primarily “shortwave” (UVB and UVC) energy. Upon exposure to UVC light
(specifically <240 nm), oxygen molecules (O2) split into oxygen atoms (O) and recombine with O2 to create ozone O3. The
current, long-term ozone concentration limit recommended by ACGIH, NIOSH, and OSHA is 0.1 ppm (0.2mg/m3).

DYMAX.COM W I D E C U R E ®CONVEY O R U S E R G U IDE |7
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. Contact your Dymax representative for information regarding the proper use of Dymax UV light-curing
systems.
Unpacking
Inspecting Your Shipment
Your WIDECURE light-curing conveyor will arrive in one crate. Inspect the crates and boxes for damage and notify the shipper of
box damage immediately.
Open each box and check for equipment damage. If parts are damaged, notify the shipper and submit a claim for the damaged
parts. Contact Dymax so that new parts can be shipped to you immediately.
Check that the parts included in your order match those listed below. If parts are missing, contact your local Dymax representative
or Dymax Customer Support to resolve the problem.

Unpacking Your Shipment
Follow these steps in unpacking the conveyor:
1. Remove the 4 Lag Bolts that are holding the machine onto the crate.
2. Remove the Plastic Banding that is wrapped around the machine.
3. Remove the Bottom Panel from the front of the machine to gain access to the Forklift Pockets (Figure 2).
CAUTION: Long fork lift forks may require remove of the unit’s rear panel to prevent damage to the panel.
4. Lift the machine using a forklift and place the unit in its permanent location.
CAUTION: The machine weights approximately 1,200 pounds. Exercise all safety precautions and ensure the forks are
seated sufficiently so the machine will not tip when lifted.
5. Temporarily remove the 4 blue Corner Trip Pieces. They are magnetically attached and could come loose during movement
and shipping.
6. With the machine in place, adjust the Leveling Feet so the machine’s Conveyor Bed is level and the machine does not rock on
the floor.

Product Overview
Description of the WIDECURE Conveyor
The WIDECURE conveyor system is designed to offer consistent, fast, and safe curing. Equipped with a 25”-wide belt and a 24”
curing width, this system is ideal for curing light-curable materials on larger parts or larger quantities of smaller parts. It can be
outfitted with either a longwave or a shortwave bulb, giving manufacturers the ability to cure a wider range of light-curable
materials.
Designed to help manufacturers build a more reliable cure process, users can easily control various curing parameters through a
touch-screen control panel. This feature gives the user greater curing flexibility and enables them to tailor the curing conditions to
their specific application. The system’s tightly controlled belt speed and minimal bulb degradation also allow better control over
cure. This provides repeatable curing profiles and a more reliable process with less risk of variance.
Standard Features
Adjustable Lamp Height –The system’s internal lamp may be adjusted from 4" to 24" above the belt. This allows curing of a wide
variety of larger parts.
Adjustable Leveling Feet –The conveyor is equipped with ½”-13 threaded holes with leveling feet installed. The machine also
features 4 mounting brackets with ½” clearance thru-holes, so the machine can be permanently installed to the floor.
Direct-Drive Motor –The conveyor runs off a 1/3 HP 50:1 ratio right angle gear motor, coupled to a 1:1 ratio cogged belt. The
motor is VFD controlled.

DYMAX.COM W I D E C U R E ®CONVEY O R U S E R G U IDE |9
Integrated Cooling System –After the lamp is turned off, there is a 5-minute time off delay on the irradiator cooling fans. Do not turn
off main power to the system until this 5-minute delay has elapsed. Failure to wait can cause damage to the irradiator cooling
assembly or the UV lamp.
UV Blower –The UV blower removes heat and ozone produced by the UV bulb. A 6”-round duct for the UV blower exhaust is
provided on the top of the curing system. Additional ducting should be added to vent the exhaust outside of your building. You may
need to add an additional blower to your system depending upon the length and configuration of your exhaust ducting.
UV-Resistant Belt –Belt speeds can be adjusted from 4-30 feet per minute.
UV-Light Shielding –The shielding prevents operators from exposure to stray UV light.
Ventilation System –The system’s integral vacuum hold-down ventilation system keeps parts securely on the conveyor belt. The
ventilation system has an external exhaust duct that can be attached to standard exhaust ducting. Exhausting the blower’s cooling
airflow out of the operating work environment is recommended to avoid any ozone effects on workers or materials. All medium-
pressure arc lamps generate and emit ozone during start-up and operation. External exhaust installation is recommended because
the unit produces a small amount of ozone that might be a problem when exhausted to a confined or poorly ventilated space.

Conveyor Setup
Installation and Interconnection
Your WIDECURE UV light-curing conveyor system requires minimal assembly once removed from the packing skid or crate.
1. A certified electrician should provide 460 VAC, 3Ø, 60Hz, 30A supply. The junction box on the right side of the system contains
four #8 AWG MTW wires. The electrical supply connection must be hard-wired by a professional, licensed electrician. (Figure 4)
NOTE: The machine will ship with a blank cover-plate installed. The end user shall decide whether the machine is hard-wired
with a flexible cable, or routed with metallic conduit. Suggested conduit entrances are from the top, bottom, or rear of the
machine.
2. Verify that the UV shielding is installed on the outlet side of the conveyor. The shielding is designed to minimize UV exposure to
the operator.
Figure 4. Power Supply Wiring
Figure 5. UV Shielding
3. The irradiator is mounted on a linear stage that allows the height of the curing lamp to be adjusted from the conveyor belt. Use
the control functions on the HMI to move the UV irradiator up or down as needed to allow for parts clearance and/or optimized
cure height.
NOTE:The UV light should be turned off before you look into the curing chamber to make an adjustment on the irradiator height
or for any other purpose.
