AV-OL-LI
3.0 AV-OL-LI Model
This AV-OL-LI light xture is a steady burning or ashing, low intensity LED obstruction light designed to comply with
either FAA (L810 or L-810(F)) orICAO (LIOL Type A, B or E) requirements. The model can be used for marking obstacles
which pose a threat to aircraft, such as telecommunication towers, wind turbines, buildings and other tall structures.
Avlite’s LED obstruction lights oer an ultra bright, energy ecient and cost eective lighting solution.
The light xture is available in DC (24-60VDC). The advanced light optic uses a single LED for minimal power consump-
tion. The corrosion resistant, polycarbonate lens is specically designed for use with LEDs to maximize light intensity
and uniformity.
The light xture incorporates internal diagnostic checking and an alarm contact for remote monitoring. The alarm relay
will be released whenever there is a problem e.g. no power, supply voltage too low, LED failure, etc. The alarm relay
will remain energized during the day when operating normally.
3.1 Available Options

5.0 Safety Information
Before proceeding with installation or service, make sure the following conditions are met:
• Ensure power lines are not ‘live’ (NO ELECTRICAL HAZARD)
• Avoid touching live circuits!
• Avoid touching any component or any part of the circuitry while the unit is operating. Do not change components
or make adjustments inside the unit with power on.
• Make sure the light xture mounting is vertically aligned to guarantee the required beam pattern of the aireld
light.
• Make sure any nearby obstacles do not impede the lights’ beam pattern.
• When installing, comply with all local electrical code(s).
• Mains power should always be disconnected when work is being done in close proximity to electrical ttings, and
electrical work should only be done by a licensed electrician.
• Operate the light only within the indicated electrical ratings and product usage instructions.
• To ensure that the light and peripheral equipment function safely and correctly, use cable in compliance with the
eective local electrical code.
• Do not stare at the LED or shine the LED into your eyes or those of another person.
• Dispose of the product according to the local laws and regulations for your region, for example, at a recycling
centre that accepts electronic devices.
• Ensure the tower or mast is grounded (NO RF HAZARD).
• Check the mast lighting circuit is not faulty.
• Make sure the mounting pole is vertically aligned to guarantee the required beam pattern of the obstruction light.

10 Single Low Intensity Obstruction Light
AV-OL-LI
6.0 Operation and Setup
When powered up, the light will constantly check day/night status using its internal ambient light sensor. The ambient
light sensor averages its measurement for 30 seconds.
FAA: By default the lights turn ON when the ambient light decreases to not less than 35 footcandles (376.7 lux) and
turn OFF when the ambient light decreases to not more than 60 footcandles (645.8 lux).
ICAO: By default the lights turn ON when the ambient light decreases to not less than 100 lux and turn OFF when the
ambient light increases to not more than 150 lux.
In night mode, the LI will be illuminated as either a red, steady burning (ICAO Type A and B and FAA L-810) or ashing
(ICAO Type E and FAA L-810F) xture. In day mode, the xture will not be illuminated.
Light intensity & operation mode setting for FAA compliant light xture
The FAA compliant model comes pre-set to the correct intensity for L-810 steady or L-810(F) ashing burning red
obstruction light in dusk-till-dawn mode. The intensity and operation mode is pre-set in the factory and does not need
to be set by the user.
Light intensity & operation mode setting for ICAO compliant light xture
The xture will be supplied with the ICAO compliant optic. The obstruction light will be pre-set to the intensity setting
specied by the customer for a red steady burning (ICAO Type A or ICAO Type B) or ashing (ICAO Type E) Low
Intensity Obstruction Light in dusk-till-dawn mode. The intensity and operation mode is pre-set in the factory and
does not need to be set by the user.
Note: The ICAO Model and FAA Model have their own unique optic. The ICAO model cannot be used for FAA purposes
and the FAA model cannot be used for ICAO purposes. The model required needs to be specied at the time of order.
6.1 GPS Syncronisation
Avlite has utilised the latest advancements in GPS technology to develop an internal synchronisation system that is
incorporated into the lights. Using overhead satellites, multiple LI xtures (ICAO Type E and FAA L-810F only) are able
to synchronise with other obstruction lights set to the same ash pattern. No additional power supplies, aerials or
control systems are required, and with its microprocessor- based system, the GPS option is specically designed to
provide maximum reliability and performance over a wide range of environmental conditions.
Operating Principle
Each light operates independently and requires no operator intervention. A minimum of 4 satellites need to be in view
for the built-in GPS receiver to collect time data. At dusk, the light sensor will turn the light on. If time data is available,
the LI will come on synchronised to every other obstruction light with the same selected ash code. Synchronisation is
achieved using an internal algorithm based on the highly accurate time base and time data received from the satellites.
The satellite data is provided from a number of earth stations using atomic clocks as the time base. Continuous self-
checking ensures that the lights will continue to run in synchronisation.
Light Activation
At power-up the microprocessor checks that the internal GPS module is programmed correctly and is able to provide
valid time base and time data. Once outside with a clear view of the sky, valid data should become available within 20
minutes.
Note: Lights will not synchronise if dierent ash codes are selected.

7.0 Unpacking, Installation and Wiring
7.1 Unpacking
Unpack all hardware and inspect for damage. If there is any damage, please contact your Avlite Oce.
Retain original packing material for possible future use in shipping.
7.2 Installation and Wiring
Open the LI xture. Please see section 'Opening and Closing the LI' for further information.
Connect the provided input power cable according to DC installations as shown in the wiring diagram on the following
page.
Note: The xture must be wired by a qualied electrician.
Thread a 3/4 inch pipe thread cord grip to the LI and attach the light to an owner supplied bracket or optional Avlite
Right Angle Mounting Bracket (for low intensity xtures) with a locking nut.
Note: Make sure the mounting pole is vertically aligned to guarantee the required beam pattern of the obstruction
light. Make sure the light’s beam pattern is not disturbed by any nearby obstacles
WARNING:
LED lights contain glass components. Do Not Drop.
Always follow the instructions outlined in the product manual when cleaning the
equipment. Improper cleaning methods and use of unauthorized cleaning agents
can damage equipment.
WARNING:
Do not stare into light emitting diode (LED) beams.
WARNING:
DO NOT connect directly to an unregulated power source. Connecting to an unregu-
lated source may result in damage.

AV-OL-LI
Opening and Closing the LI
Open the Obstruction Light by removing the locking screw.
In order to open the unit, the top half of the unit should be
turned anti-clockwise with respect to the bottom half.
The top half will turn approximately 20mm over a
positive “click” before separating from the bottom half.
Attention should be paid to the restriction caused by the
internal cabling which is secured by a cable gland.
The unit is closed by reversing the above procedure,
ensuring the black rubber O-ring remains in place.
Replace O-ring if perished.

9.0 Troubleshooting
Problem Possible Cause Solution
Light will not activate No power to light • Check battery terminals are properly connected.
• Check battery voltage is above the at battery
threshold.
Ambient lighting
conditions
• Ensure internal toggle switch is set to the ‘ON’
position.
• Ensure light is in darkness.
• Wait at least 60 seconds for the program to
initialise in darkness.
Light will not operate
for the entire night.
Insucient Charging • Expose light to direct sunlight and monitor
operation for several days. Avlite products
typically require 2.5-3.0 minimum hours of direct
sunlight per day to retain full autonomy. From
a discharged state, the light may require several
days of operational conditions to ‘cycle’ up to
full autonomy.
• Ensure solar module is clean and not covered by
shading during the day.
Lights are constantly
on during the day.
Incorrect Operation
Mode
• Check the Operational Mode setting in AvlitePro
is not set to ‘Always ON’
