SETUP / Unpack
•Carefully unpack the unit and accessories from shipping carton.
•When removing the LED Head, ensure that the optical window is not placed directly on
a surface to avoid any damage.
1.1 System Requirements
In addition to the V LED Head, you will require the following components:
•Power supply
•Power cable
Note: You will also require a PLC controller or RS485 cable unless you are using an
existing controller. The PLC controller is used to discover the extensive functionality of
the V LED Head, but integrators can access the full feature set through integrating
with the PLC or RS485 interface directly. Refer to “Connecting the U LED Head”
documentation in the ser Guide
Connecting the Power Supply and PLC Controller
Note: All connectors are via screw style fastener -- do not over tighten the
connector screws.
Note: The following is a generic procedure, illustrated with the common
components described above. Refer to “ Connecting the Power Supply and
PLC Controller” documentation in the User Guide
Tip: After securing the power cable to the power supply, it is recommended to
tie-off” the female connector cable on to the mounting brackets or process
rigging as a form of strain relief.
1. Make sure the power supply unit is turned off.
2. Connect the AC power cord
to the power supply.
3. Attach the male end of the
power cable to the power
supply unit, and connect the
female end of the power
cable to the UV LED Head
per Figure 1 – AC8300P-HD
shown.

1.2 Powering Up and Powering Down
1. Ensure that the system has been properly installed and the V LED Head is securely
mounted with the optical lens in the desired orientation. Refer to “Mounting the U
Head” documentation in the ser Guide
2. Verify that the power supply unit’s AC supply cord is connected to a properly grounded
AC outlet.
3. If the power supply has a circuit breaker, switch it to the “ON” position.
4. Turn the main power switch of the power supply to the “ON” position and check the fan
for airflow.
5. The LED indicator on the V LED Head will flash green during “boot-up” and change to a
steady green indicating V LED Head is ready for use. It is recommended to wait for 15
seconds from initial power-up before attempting to control the V head. For more
information about the indicators. Refer to “Using the LED Head” in the ser Guide
1.3 Using the LED Head
The peak wavelength of the UV LED Head is 365nm, 385nm, 395nm, or 405nm +/-
5nm, depending on model.
For all models, adjusting the UV LED Head intensity can be actuated by an external
controller via the PLC interface. Refer to “Connecting UV LED ead”
documentation in the User Guide
Input voltage vs. desired intensity; 5V = 100% and 1V = 20%. A minimum voltage of
1V is required for light source operation.
Note: The light source will maintain a 20% intensity when the input voltage is in the
range of 0.5V. If the input voltage is below this, the light source will turn off.
Ensure the UV LED Head indicator is illuminated to a steady green before applying
UV power to the head. The UV LED Head indicator will illuminate to a steady amber
indicating UV is on. When UV is off, the indicator will revert back to a steady green
indicating UV is off.
The UV LED Head is capable of responding to PLC control signals in less than 0.2
seconds. Understanding the LED Indicators

1.4 Symptoms and Possible Causes
If the system fails to power up:
•Make sure the AC power cord is securely plugged into a functional AC
outlet and into the AC inlet on the power supply unit.
•Make sure that the circuit breaker on the power supply unit is not tripped.
If so, reset breaker.
•Make sure all cable connections (power supply to V LED Head) are secure.
•Ensure that the power supply is switched on and the green LED indicator on
the front panel is lit.
•Make sure the door lock electrical loopback on the PLC is installed properly.
If the system powers up but experiences a thermal fault during operation:
•Ensure UV Head is installed with adequate clearance around intake and
exhaust ports.
•Ensure intake air filter is not clogged or obstructed.
•If filter is clogged, either clean with compressed air or replace with a new filter
insert.
If the system powers up but does not emit U :
•Check that the door lock loop is intact.
•Ensure that the voltage levels on pins 2 and 3 of the PLC interface match the
logic required to enable the LEDs.
•Check the visual indicator for signs of a fault.
If a fault condition has been detected:
•Attempt to clear the fault by cycling power to the LED Head or by pressing
the “Clear Fault” button on the PLC 2000 controller.
If the system exhibits a fault condition with a slow-flashing red:
•Power-cycle the V Head to clear.
If the light intensity is too low:
•Make sure the input voltage is at least 46V (input voltage to the Head for the
purposes of powering the head is typically 48V (46-50V DC)).
•Clean the optical window of the V LED Head as described in Section 9.3, of
the ser’s Guide, “Cleaning the LED Head”.
•Verify that the intensity level of the V LED Head is set to the correct level,
using the PLC Controller.
