For your safety
Please refer also to the relevant Technical Data Sheet for the adhesive to be processed.
Download from www.loctite-equipment.com or request the Technical Data Sheet and the
Safety Data Sheet (acc. to EC Directive 91/155/EC):
Henkel AG & Co. KGaA
+49 89 92 68 11 67 for the English language version of the data sheet;
089 92 68 11 22 for the German language version of the data sheet.
INSTRUCTIONS given in these data sheets must be followed scrupulously at all
times!
While under warranty, the unit may be repaired only by an authorized Henkel service
representative.
Warning!
Follow the manufacturer's instructions! Request a Safety Data Sheet for the Loctite®
product to be processed!
Controlling or calibrating this product by other than the procedures stipulated here could
cause exposure to dangerous LED radiation.
Damage to the power cord, the housing or the power adapter can result in contact with
live electrical parts.
Check the power cord and the unit before each use.
Never operate the system if the power supply unit / power cord is damaged! Replace a
damaged power supply unit / power cord with a new one.
Do not look directly at LED-UV light, or at LED-UV light reflected in a mirror or other reflective
surface. Doing so could cause eye damage.
Install the LED head in a way that humans are not exposed to LED-UV light.
Exposure could injure the skin or eyes.
Always turn off the key switch, before cleaning the LED head.
Cleaning the head while the switch is on could cause eye damage or injury to the skin.
Never disassemble this product. Disassembling this product could cause exposure to LED-
UV light, causing eye damage or injury to the skin.
If there is a risk of the LED-UV light being exposed to UV reflective light, place the product
inside a cover with proper reflectance and heat characteristics to block that reflected light.
When operating the controller, set up the system so that the path of the LED-UV light is not
at eye level.
It is strongly recommended to place a protective barrier around the product so that people
cannot approach it while it is operating.
Wear protective UV glasses and other protective clothing during operation.
Never operate this product in a manner not described in this manual. Doing so risks
exposure to LED-UV light.
Do not use any input power supply outside the specified range.
Do not use this product in a place where a large vibration or impact can be applied.
Never disassemble, repair, or modify this product in any way other than specified in this
User Manual.
We cannot be held responsible for damage or injury of any kind because of failure to
observe the instructions in this Operating Manual.

General Instructions
–Do not connect this product to any power supply outside the power supply voltage and
frequency range indicated on the main unit and in this User’s Manual. Otherwise, this
product may be damaged.
–Do not place anything on the controller or block the air vents around this product to
prevent the occurrence of burns due to overheating.
–When handling the LED head, do not touch the lens or LED with bare hands. If a
foreign substance adheres to the lens or LED, it can cause the UV intensity to
decrease and the curing performance to degrade. If contaminations are applied to the
lens or LED, wipe it clean with alcohol and a lint-free cloth.
–Be careful not to drop or apply shock to the LED head. Doing so may damage this
product.
–Do not repeatedly bend the connection cables of the LED head, as this may result in
breakage. If any part of the LED head is broken, the whole LED head must be
replaced.
–Set the rubber feet of this product on a flat horizontal surface. Do not tilt this product or
put it on its side or upside down during use. The product may overheat and be
damaged.
–Do not use any other cable than the supplied connection cable to connect the LED
head to the controller.
–Ensure that the connection cable approx. 80 mm from the connector is kept free from
flexing stress and the joint between the connector and the cable is kept free from
tension. Otherwise, the cable may be broken.
–If the connection cable is longer than 2 m, or if the product is installed inside a larger
equipment, set up a display near the LED head so that the “LED radiation warning” can
be seen immediately. If you use OUTPUT terminals “+5V” (23) and “COM” (24) at the
rear of the controller, these will output a signal when the power is switched ON.
–Never connect any LED head, connection cable, AC adapter, or UV sensor to the main
unit, other than those designated by Henkel. Otherwise, any failure, loss, or damage
that may occur will not be covered under warranty.
–Never try to disassemble or modify the product, or to alter its internal settings. Any
failure or damage that occurs after disassembling or modifying the product will not be
covered under warranty.
Explanation of the Label

Please observe the following
When using more than 1 Unit
When using more than one controller, do
not bundle the supplied AC adapters
together. The AC adapters may overheat
and damage the products.
Ventilation
Cooling air is drawn through ventilation slots in the side panels of the controller. Do not
obstruct any of these air vents to make sure that ventilation air circulates throughout the
system. Obstruction of these openings will cause the unit to overheat.
Explosive Zones / Earthquake Zones
This unit is not specified for operation in explosive zones.
If operated in earthquake zones, the unit must be securely fastened.
1.6
Special Instructions
How to handle the Lens
Any contamination which has not been removed, such as fingerprints on the glass, will
bake to the surface and result in premature deterioration of performance.
☞
Note!
Fingerprints can be removed with a lint free wipe and pure alcohol. Before reassembling
the lens into the unit the alcohol must have evaporated completely!
Repair and Servicing
Refer all repairs to an authorized Henkel service center.
1.7
Features
LED Lamp Life
Based on an average power-on time of 8 hours per day and normal service conditions,
the lamp has an expected service life of 20,000 hours (Total irradiation time before the
UV intensity becomes 70% of the initial value).
Power irradiation
High-power irradiation 8,000 mW/cm2is standard when a 3 mm lens is used. It is
measured with a UV dosimeter type 98787, oder no. 1390323. Usually the unit is
purchased with a 6 mm lens.
UV curing without temperature increases
A single 365-nm LED UV light source is used, which does not include infrared radiation.
This eliminates the risk of heat damage to the workpiece.
Stable UV intensity
UV intensity is kept constant, even if the ambient or LED temperature changes.

Please observe the following
Use in a Clean Room
No cooling fan construction allows the use in a clean room. There is no need to deal with
exhaust. No ozon is generated.
Programmable UV irradiation with four individually controlled heads
Each LED head can be independently controlled by one controller. The heads can also
be controlled all together or in combination. Up to 7 different operation programs can be
stored for each channel (LED head), including one program for the constant intensity
irradiation and 7 programs composed of up to 10 steps each. Each channel can be
started separately. To setup such programs it is necessary to use the software and a PC.
The start of each program is possible only with an external start signal.
Program Examples
Operation Mode for each LED head with a start via button START/STOP or connected
footswitch:
Up to 7 individual programs can be set via PC, see section 5.8.2:

Description
2.2
Theory of Operation
The radiation cycle can be initiated with the button “START/STOP” in the front panel,
with a footswitch (sold separately), via PLC connection with an external start signal and
also via a PC connection.
Each channel can be started separately or all simultaneously.
The UV LED Curing System EQ CL25 High Power LED Spot Cure offers the possibility
of programming of each channel with 7 programmes each containing up to 10 steps only
via PC connection.
Within the programmes the value of intensity and time can be adjusted and changed for
each step.
This can be done only via a PC (RS232).
For the possibility to check the irradiation output of the LED head an optional UV power
meter is necessary. The power meter has to be ordered separately.
The intensity of each LED head can be calibrated and monitored. If the level is below of
an adjusted value an error message is available at the output interface. It is also
displayed on the controller.
2.3
Operation Modes
2.3.1
Time Controlled Mode
In this mode the unit can be started easily with setting curing time and intensity only
2.3.2
Continuous Mode
With this curing mode the irradiation can be started with the button START/STOP 1and
stoppes by pressing the button START/STOP 1again. The channels are started
simultaneously.
