1 Introduction
The OmniCure® LX500 series represents a new standard in UV LED Curing. It gives you the power, control, and
reliability never before available in such a form factor, providing configuration flexibility to suit any application for
end users and integrators alike.
The UV LED Head Controller allows optical output to be controlled manually via touch pad control, or by PLC or
PC (Virtual COM Port) USB interface. The UV LEDs are enclosed within the UV LED Head which provides excellent
spectral and power output. The UV LED Head has a typical lifetime in excess of 20,000 hours of accumulated 'on’
time at either 365nm or 385nm wavelengths.
The output power emission of the available UV LED Head is adjustable in 1% increments from 5% to 100% to
provide light for your application. In order to set your OmniCure LX500 series at specific irradiance levels (W/cm2),
we suggest running trials to optimize the results for the UV cured glues and adhesives used.
In the Excelitas Technologies family of UV LED light systems, all systems offer the same high level of innovation,
quality and reliability that our customers have come to expect. OmniCure® has combined next generation optical
engineering, state-of-the art electronics and fibre-optics to produce sophisticated technologies that employ light.

5 Installing the Hardware
5.1 General Installation
1. Determine the desired UV LED Head location and position based on the results of a series of testing and
trials.
2. Determine the working location of the Controller, ensuring access to the AC power source does not cause
any possible obstruction with the power cable connection from the source to the controller. The main
power switch is located on the front panel of the unit. The unit should be placed so that the switch is
convenient for the operator to access.
3. If you are not integrating with an existing controller, ensure the door lock jumper is connected.
4. Connect the UV LED Head cable to the rear of the Controller. Only use Excelitas extension cables to extend
the reach of the UV LED Head.
5. If using a foot pedal switch, connect it to the corresponding input on Controller (e.g. Head 1, FP 1). Refer to
Figure 2.
6. Install the supplied installation clamp to the existing fixture using either the 3 metric threaded screw holes or
the 3 imperial threaded screw holes. The two end faces of the installation bracket are identified for metric
and imperial thread sizes. Though the clamp can be located in any position on the head, for optimum heat
dissipation resulting in optimum performance it is recommended that the clamp position on the head is as
per Figure 5.
7. Install the UV LED Head into the installation clamp and secure its location/position by tightening the hex
screw. Refer to Figure 6 for typical installation applications.
8. Attach the appropriate lens and remove the protective cap. To remove the cap, pull the cap-hat — do not
rotate the LED head or cap.
When not in use, reinstall the cap by holding the cap-hat and pushing it back over the head. This will prevent
any contamination to the lens when the head is not used for more than one day. Refer to Figure 4.
9. If you are not integrating with an existing controller, connect the door lock jumper between pins 24 and 25
(refer to Table 1). This jumper can be connected to your UV protective enclosure to prevent accidental UV
exposure during operation.
Closed contact – enable UV LED Head(s) output
Open contact – disable UV LED Head(s) output.
10. Connect the AC power cord in to the power supply and to a properly grounded AC outlet. For safe
operation, only use the power cord supplied or one with an equivalent rating, shield, and approvals.
11. Connect the power supplies DC barrel connector to the back of the Controller.
Note: The UV LED Head connectors are locking. To disconnect them from the Controller, squeeze the tab on the
plastic shell.
5.2 Clamp Installation and Removal
1. Ensure the clamp locking screw (M4 x 10, Allen key size 3mm) is loose before slipping the clamp into the LED
lens and head assembly.
2. Slide the clamp over the lens housing and onto the head and tighten the locking screw. For optimal
performance and ease of changing lenses, position the clamp so the bottom face is located between the
lens housing crease and the reference line (first circular groove) on the head body. Refer to Figure 4 and
Figure 5.
3. To remove the clamp loosen the locking screw and slide the clamp off the lens and head assembly.

5.3 Changing Lenses
Do not use any mechanical tool when removing or replacing the lens/housing.
Hand tighten only, do not over tighten as this will make the assembly difficult to remove.
The lens and housing are one subassembly. Do not attempt to remove the lens from the housing.
Ensure the system is off and the head has cooled to room temperature before changing the lens.
Holding the head firmly unscrew the lens housing and replace with desired replacement lens. Refer to Figure 4.
It is recommended to clean the replacement lens thoroughly prior to replacement. Refer to Section 8.3 Cleaning
the LED head and Lens assembly. When not in use, place protective cap over the lens.
5.4 Storing LED Head and Lens Assemblies
When not in use, store the head and lens assembly individually wrapped in a clean, lint free bag in a safe, dry
place.
Never store multiple unwrapped head and lens assembly in the same bag, as they may become damaged if they
come in contact with each other.

035-00628R
Main Control Panel
Displays upon start-up; shows current state of each
connected UV LED Head (displays two or four channels
depending on Controller model).
The timer for each channel is how long (in seconds)
the UV LED Head will remain on when an exposure is
triggered. If the timer is displaying 0.0 seconds then
the unit is in “count up” mode and the UV LED Head
will remain on for as long as the enable signal is
present. If in count up mode, the timer value cannot
be changed.
The intensity is represented by both a numerical value
and a bar graph. If calibrated for irradiance, the
number will be a decimal without a ‘W’, if a decimal
number with a W is shown, the head is calibrated for
power mode. The color of the intensity bar will be
same as the color code on the UV LED Head. The
intensity will be displayed as a percentage for un-
calibrated heads or in W/cm2 or W for calibrated heads
(refer to Section 8.5, ”Calibrating a UV LED Head”).
Closed loop feedback will be engaged for intensities
below 100%. When closed loop feedback (CLF) is on,
an icon will appear beside the intensity bar for that
channel. The CLF icon appears when CLF is actively
controlling the output of the head. If the CLF icon
disappears before the completion of an exposure, then
CLF has reached the upper limit it can adjust for and is
no longer functional. If CLF usage is desired, it is
recommended that you use an intensity of 80% or less.
The bottom of the screen shows the last event. If you
have an SD card installed this event will be saved to a
log file. (refer to Section 8.6, ”Viewing Log Files”).
When the system experiences an alarm, the alarm icon
beside the Head number will turn red and an alarm
message will pop up.
StepCure
Use to control the UV LED Head operation for
sequence programming and S2000 compatibility. For
more information, see Section 6.4,”Defining Exposure
Parameters”.

The Usage bar shows the capacity of the SD card; the
middle number reflects the current free space on the
card.
6.3 Closed Loop Feedback
This symbol means that the LED is currently being closed loop feedback controlled. Every time an intensity
adjustment is made, whether by front panel or PC control, a new set-point must be acquired. This occurs 500ms
after the LED is turned on, and is used during every subsequent exposure. If your exposure timer is less than
500ms, this set-point will never be obtained. Once the intensity adjustment limit is reached, CLF will be disabled
due to an inability to increase the output intensity. When this symbol is displayed, CLF is active on the associated
channel.
6.4 Defining Exposure Parameters
Programming an exposure
Use the Main Control Panel to change the timer or intensity for each UV LED Head:
 Use the arrow keys to highlight the field you wish to change. The text in the highlighted field will turn red.
 Press Select to select the field you wish to change. Selected fields will begin to flash.
 Use the up and down arrow keys to change the value of the field. Holding down an arrow key will increase how fast
the value changes.
Programming multiple steps or multiple heads
Use the StepCure screen to configure input signals to trigger a step profile of one or more heads. StepCure allows

 Running a sequence of exposures on one head, at varying times and intensities.
 Running a sequence of exposures on multiple heads, at varying times and intensities.
 Running parallel exposures on multiple heads, each can be at a different time and intensity.
 Programming multiple programs for the same head from different trigger sources.
 Setting which head will be controlled by the S2000 command set.
Note: If no head is programmed to respond to the S2000 command set, sending S2000 commands will return
errors.
Note : For customer interfaces designed around the S2000 lamp based system migrating to the LX5
system, the S2000 command set is compatible with the LX5 via the PC USB interface. Please contact
Excelitas for more information regarding the S2000 Command Set.
Note: A StepCure program can only be run by using the trigger source specified. If another trigger source (not
assigned in the StepCure screen to a program) is triggered, the head will run the profile specified on the
main control screen.
Note: StepCure ONLY functions if the unit is in countdown mode. If the unit is in count up mode, StepCure will
not function. (Exception is S2000 command set setting.)
For each step define the following:
 # –which UV LED Head is being controlled
 Time – the exposure time in seconds
 Level – the intensity of exposure, this will inherit the current status of the head connected. If the level is to be an
irradiance, calibrate the head using an LS100, then set the irradiance value. If the level is to be a power, calibrate the
head using an LS100P, then set the power value. If the StepCure program level differs from the connected head, an
error will occur during StepCure execution.
 Dwell – the delay in seconds until the next step is performed
 Src – the source (input signal) which will trigger this step.
To clear any line, select the value in the # field and, using the arrow buttons, cycle down until it is blank.
Example 1: Setting up a step profile
# Time Level Dwell Src
1 1 1.5 75 0.1 PLC1
2 1 5.0 100 2.0 PLC1
3 1 2.0 50 0.1 PLC1
A signal on the PLC pin “Enable 1” will turn on head 1 for 1.5s at 75%, then off for 0.1s, then 100% for 5.0s, then off
for 2.0s, then 50% for 2.0s.
Example 2: Controlling multiple heads with one input control signal
# Time Level Dwell Src
1 1 1.0 80 0.1 Fp2
2 2 1.5 65 0.1 Fp2
3 3 0.5 99 0.1 Fp2
4 4 10.0 25 0.1 Fp2
A signal on the foot pedal #2 connector will trigger an 80% exposure on head 1 for 1.0s, then a 65% exposure for
1.5s on head 2, then a 99% exposure on head 3 for 0.5s and then a 25% exposure on head 4 for 10.0s. There will
be a 0.1s delay between each step.
Example 3: Controlling multiple heads simultaneously with one input control signal
