6.0 Operation and Setup
Avlite’s AV-OL-310 is a robust, completely self-contained solar powered LED light. The solar
module of the light converts sunlight to an electrical current that is used to charge the
battery during daylight hours. The battery provides power to operate the light at night. For
optimum solar charge performance it is recommended that the unit is orientated with the
solar panels facing East-West.
FAA: By default, the lights are designed to turn ON when the ambient light decreases to not
less than 35 foot-candles (376.7 lux) and turn OFF when the ambient light increases to not
more than 60 foot-candles (645.8 lux). These limits can be factory adjusted, if required.
ICAO: By default, the lights are designed to 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. These limits can be factory adjusted, if required.
6.1 AV-OL-310
External ON/OFF Switch
The lights can be fitted with an external ON/OFF switch below the solar panel at the base
of the unit. The ON/OFF switch may be useful if the unit is only required for short periods
(i.e. it is being moved or needs to be stored often) ,and disconnecting the battery is not
viable.
External Battery Charging Port
The lights can be fitted with an external battery charging port which can be found below
the solar panel at the base of the unit. This can be used to recharge the battery if the
light is being stored for more than 1 month or if the amount of sunlight is limited (e.g.
in challenging solar locations or during Winter months). Please see ‘Long Term Battery
Storage & Maintenance’ in the Maintenance & Servicing section of this manual. A suitable
battery charger may be purchased separately from Avlite.
Remote Monitoring and Control
Avlite offers remote monitoring via GSM or SATCOM. Operators can remotely monitor the
status of their installation from a compatible device. The system can also be configured
to send out SMS text messages or e-mail alerts to designated operators should alarm
conditions be triggered, such as low voltage or light failure.

Installation & Service Manual
Latest products and information available at www.avlite.com 15
6.1.1 GPS Synchronisation
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 obstruction lights set to the same flash pattern will flash in unison. No additional
power supplies, aerials or control systems are required, and with its microprocessor-
based system, the GPS option is specifically 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 light will come on
synchronised to every other light with the same selected flash 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 light 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.
Daylight Operation
During daylight hours the microprocessor is in idle mode to reduce power consumption.
Time data continues to be updated once per second. The microprocessor will automatically
exit the idle mode as soon as dusk conditions are detected.
Night Operation
When dusk conditions are detected the light will carry out the following:
• Check for valid time data and turn on after a delay based on the current time and the
length of the selected flash code.
• If valid time data is not detected, the light will turn on after approximately 10 seconds.
This light will not be synchronised.
• If the light turns on unsynchronised, it will continually check for valid time data. Once
valid data is found, the light will automatically synchronise.

7.2.1 Location
For best light performance, the light fixtures should be installed in an area where the solar
modules are not covered and are in clear view of the sky with no shadows.
7.2.2 Factory Configuration
Prewired and preassembled AV-OL-310 solar light fixture
7.2.3 Selecting Operation Mode and Preset Configuration (FAA L-810 and ICAO Type A
and B)
Refer to section ‘AV-OL-310’ for appropriate diagrams.
1. Remove the 4 socket-head screws on the lens assembly.
2. Remove the 6 Philips Head Screws from the underside of the light head and
remove the Access Cover (GSM and Satcom models also require the removal of the
communications board with four Philips Head Screws).
3. Set the DIP switch to the required settings. The operation mode and preset
configuration of the light is adjusted by setting the INTENSITY DIP switch which controls
the Operational Mode and the Type of Obstruction Light required. Refer to section
‘Operation Mode and Preset Configuration Setting’ for DIP switch settings.
4. Replace the Access Cover and connect the lantern power connector to the interfacing
cable to power up the unit. (Replace the communications board if applicable).
5. Place the top lens assembly back onto the light body and replace the 4 x socket head
screws. Avlite recommends that the Light Head be tightened to the Solar Chassis Base
using the general purpose ‘Grip Tool’, similar in shape to a screwdriver, however with the
appropriate Hex Key Head fitted. The torque setting applied to each of the 4 Hex Bolts
should be sufficient enough to ensure that the Light Head Base is secured firmly, but not
over tightened with excessive force. Recommended torque settings for fitment of light
heads to solar base units using the supplied 4 Hex Bolts is 3Nm for a satisfactory seal.
Note: Applying a higher torque setting is not recommended and may void warranty. If in
doubt, please contact your local Avlite representative.
6. Check the O-ring and ensure that it is fitted correctly in the O-ring groove.
7. The unit is now ready for normal operation once placed in darkness.
8. To test, place a dark cover (towel or jacket) on top of the light to activate the sensor and
ensure that the light turns on.

Replacing the Battery
The AV-OL-310 has an internal battery compartment, which provides the user with the
ability to change the battery after years of operation.
1. Remove the four socket-head screws on the top lens assembly and separate the AV-
OL-310 lens assembly from the body/base section.
2. Remove 2 x M2 SHCS & washers from the top battery bracket.
3. Separate the light head at the connectors.
4. Lift the upper battery bracket out of the AV-OL-310.
5. Disconnect the old battery
6. Remove the old battery from the chassis.
7. Discard old battery in a safe manner.
8. Reconnect the new battery.
9. Place battery back inside light body, and position the upper battery bracket in the top
of the chassis.
10. Secure using 2 x M4 Cap screws & washers.
11. Feed all wiring back inside light body, and make sure the O-ring is properly placed at
the top of the light body.
12. Please realign bidirectional indicators on the base with the light head to ensure correct
alignment of the light output on the runway.
13. Place the top lens assembly back onto the light body and replace 4 socket head
screws. Half tighten all 4 socket head screws, and then fully tighten each socket head
screw to ensure an even seal.
• It is recommended that the bolts for holding the light heads to the Solar Base units
have a torque setting applied of 3Nm for a satisfactory seal. Applying a higher Torque
setting is not recommended and may void warranty. If in doubt, please contact your
local Avlite representative.
14. To test place dark cover (towel or jacket) on top of light to activate sensor, light will
come on.
Care must be taken to observe the polarity of each wire before they are connected.
To ensure waterproofing of the unit, make sure that there is an even seal.
Safe Battery Handling
Charging and Discharging
• Always ensure batteries are fully charged when installing new lights. The light will be
dispatched from the Avlite factory fully charged. However if time has elapsed between
dispatch and installation, battery voltage must be checked.
• Never short-circuit or reverse polarity of a battery, damage to the battery and device
may occur, and there is a risk of fire.
• Do not use different types of batteries in the same battery assembly. Sealed lead acid
and NIMH do not mix.
• If the battery has been deep-discharged, a prolonged charging time is required to bring
the battery back to full capacity.
