SYSTEM DESCRIPTION
The light is set to flash at 20 flashes per minute.
A precision molded lens on each LED enables the required light intensity to be achieved with low power
consumption.
The intensity of the light is 2,000cd (±25%) according ICAO and FAA requirements.
The light will operate at night time only according to the ambient light level.
The light will automatically flash in unison with other L350-864-G lights, and other Orga/TWR Lighting,
Inc. L350-864 lights that are used in a system with an Orga/TWR Lighting, Inc. CIPxxx controller and an
Orga/TWR Lighting, Inc. GPS020 or GPS030 flash synchronizer.
The light will take up to 90 seconds to turn on when power is first connected, and up to 15 minutes for
the light to synchronize with other L350-864-G lights, depending on the availability of a proper GPS
satellite signal.
If power is disconnected it may take up to 15 minutes for the light to re-synchronize with other lights,
depending on the availability of a proper GPS satellite signal.
An internally installed control unit uses the latest microprocessor technology, and provides the
necessary functions for a trouble free, long service life. The control unit continuously monitors the
status of the light and gives an alarm in the event of a malfunction. The alarm can be monitored using
the alarm wires of the Strobeline cable (volt free contact status change) and is presented as a visible
alarm with a small red LED on the photocell.
The light will automatically turn itself off if 25% or more of the LEDs are not operating. The alarm will be
activated.
The light is provided with an internal flash synchronizer mounted inside the dome. The flash
synchronizer uses information from the GPS satellite system signal. All L350-864-G lights will flash in
unison with each other. If the light is not correctly synchronizing from the GPS satellite signal the alarm
will be activated.
The light has a built in photocell, mounted in the base under the hinge point. The light will operate in
either day (off) or night (flashing) mode depending on the ambient light intensity conditions. In the event
of a photocell malfunction the light will automatically operate continuously (flashing mode), and the
alarm will be activated.
2.1
The light fixture
The use of UV stable and high impact resistant polymers makes the light low in weight, easy to handle
and to install. The light fixture is easy to open for maintenance access and is weatherproof.
The base and top ring of the light fixture support an acrylic dome. The dome is provided with a bird
spike facility.

UNPACKING
Receiving the equipment
Before unpacking, check if the packing shows any signs of damage.
After opening, check the contents against the delivery slip. All items should be inspected separately for
visible damage. Report any damage or loss claims immediately to the freight handler and take any
necessary steps to protect your rights.
3.2
Handling
o Do not pick up or hold the light by the bird spike on the top of the dome, always hold and
support the light at the base.
o Labels on the outside of the package show the top and bottom. Open the right way up.
o The light must always be handled with care.
o Do not change or remove any labels from the equipment.
3.3
Pre installation test
If possible it is recommended that the light is tested on site before it is installed on the structure to
confirm the correct operation.
The light can be tested by connecting a 100-240 VAC (±10 %), 50-60 Hz power supply to the power
wires of the Strobeline connection cable. Take suitable precautions when making electrical connections.
Note that the L350-864-G light does not flash during day time, to test the light during daytime it is
necessary to completely cover the photocell unit with an opaque shroud to prevent any light reaching
the detector before the power is connected. The light should start to operate approximately 90 seconds
after the power is supplied. If power is connected when the photocell detects daytime light conditions it
may take up to 5 minutes to change to night mode after the photocell is covered.
CAUTION!
It is assumed that the incoming power supply is suitably protected at the site distribution board.

INSTALLATION
o Read this manual in full before starting.
o Check that there are no signs of damage to the light. Clean the outside of the light if necessary
with detergent and water (do not use solvents).
o Follow the mechanical installation instructions, ensure that the light is correctly mounted and is
levelled.
o Make sure the bracket on which the light is mounted is directly connected to a good ground
(earth) point with minimum 6AWG cable.
o Make sure that the outer braided shield of the Strobeline cable is correctly attached to the EMC
cable gland used to fit the Strobeline cable to the junction box.
o Make sure that the electrical connections are properly made in the junction box using secure
terminal connections – do not use “wire nuts”.
o Make sure that the earth terminal of the junction box is directly connected to a good ground
(earth) point.
o Make sure the junction box to which the light is connected is directly bonded to a good ground
(earth) point with minimum 6AWG cable.
The location and positioning of the L350-864-G light(s) on the obstacle must be made in accordance
with the applicable ICAO Annex 14 Volume 1, FAA AC70/7460-1, Transport Canada CAR and/or other
applicable local regulations.
Ensure that the light can be seen from all horizontal approach paths and that it is not shielded from view
by other equipment.
NOTE!
This warranty is declared to be null and void if Orga/TWR’s inspection indicates that items have not
been installed according the instructions and diagrams in this manual.

4.1
Installation location considerations
The light will be typically located on the top of structures that, due to their nature, will potentially be
subject to lightning strikes.
We assume that the structure is provided with an adequate primary lightning arresting system (for
instance in accordance with NFPA-780 or DIN 48801) that will guide the energy directly to earth.
The Orga/TWR Lighting, Inc. design is based on extensive consultation with experts in the fields of over
voltage protection and the effects of lightning discharges. Over voltage surges on control signals, data
or power supply lines can cause considerable operational disruption, note the following installation
considerations:
o Protect the light with a lightning rod (air terminal). Maintain the correct distances between the
lightning rod and the light (see Figure 2 – Distance between the lightning rod and the light).
o Reduce the chance of a lightning strike affecting the cable by minimising the exposed cable
length.
o Protect the power supply, monitoring device and communications devices to which the light is
connected with over voltage protection devices.
Figure 1 - Distance between the lightning rod and light
The Strobeline™ cable has an outer braided shield that, when used with the correct EMC cable glands
at the power connection junction box will provide an effective equipotential bonding system between the
system components when this is directly connected to a good ground (earth) point. This ensures that
any secondary lightning current (which will occur as the impedance of an obstacle from the top of the
structure to earth will never be zero) will flow through a controlled path. This ensures that this current
does NOT run through the light and as a result damaging or even destroying the light.
16
L350-864-G - Installation & operation manual
4.2
Mechanical installation
CAUTION!
For installations where the light will be exposed to high RF (radio frequency) radiation, special
precaution measures must be taken. Please consult Orga/TWR prior the installation.
The location and positioning of the light(s) must be done according the applicable ICAO Annex 14,
Volume 1 or FAA AC70/7460-1 or other applicable local regulations.
The light must be positioned so that the photocell is able to measure representative ambient light levels.
Position the light fixture so that the photocell has the clearest possible view of the ambient environment.
Make sure that the photocell is not directly shielded by nearby structures which would mean that it is not
reading the proper ambient light level.
The GPS antenna mounted inside the light needs to be able to receive satellite signals for correct
operation. Position the light fixture so that the GPS antenna has the clearest possible view of the sky
and horizon in all directions. Avoid placing the light adjacent to large areas of conductive metal as this
may cause poor signal reception, and as a result loss of synchronization.
The light is designed to be mounted on a secure and level horizontal surface, in a position that meets
with the unrestricted visibility requirements. Due consideration must be given to accessibility, especially
the ability to open the light during routine service and maintenance, please make sure that the light is
positioned to allow the light to be fully opened.
Four equally spaced fixing holes are provided, to fit 12 mm (1/2”) fixing bolts arranged on a 336.5 mm
(13.25”) circle diameter / 240 x 240 mm (9.5”) square pattern. The light needs to be leveled by using
lock nuts and/or spacers on the fixing bolts. (See standard mount drawing.)
When not using a standard Orga/TWR provided mount the following mounting methods are
recommended.
The secure and level horizontal mounting of the light is important to maintain the design photometrical
characteristics, the ingress protection, the loads on mounting points, cooling and overall reliability.
Ensure that there is a gap between the light and the mounting bracket (see Fig 2).
L350-864-G - Installation & operation manual
17
CAUTION!
Take extreme care that all 4 mounting points rest comfrtably on the mounting surface before
tightening the bolts. Not paying attention to this while tightening the bolts can result in serious
damage to the base. The mounting torque should be 10-12 Nm.
Method for leveling is to use a mounting bolt with a
- Length of 3,5” – 4” inch (90 – 102mm), and
- Thickness (diameter) of ½” inch (12mm)
- Material: silicon bronze (if it is not possible to use silicon bronze then use stainless steel).
25-50 mm (1-2”)
Mounting bracket surface
Figure 2 – Mounting of light to bracket
Provide the required quantity of nuts (same material as the bolt), spring washers and flat washers for
each bolt. See Figure 2 – Mounting of light to bracket Support the light on the mounting bolts as shown
above so that there is a gap between the light and the mounting bracket surface.
Use the spirit-levels that are mounted on the lens ring as level indicators. Leveling is extremely
important to assure that the light will be pointing in the correct horizontal plane, to provide the proper
obstacle light visibility to air traffic and to prevent light scatter at ground level.
Figure 3 – Spirit-level
CAUTION!
When not using a standard Orga/TWR provided mount, please ensure that the base of the light is 25
- 50 mm (1- 2“) distance above the mounting surface (see Figure 4 – Mounting bracket surface). This
is to prevent damage caused if any water between the base and the mounting surface should freeze
and expand, thereby damaging the base.

Earth Grounding of the system
The correct operation and protection of this Orga/TWR Lighting, Inc. obstacle light system depends on
the system being correctly protected from over voltage and electrostatic discharges by ensuring that the
light system is correctly connected to the earth.
The light(s) should be protected by an air terminal (lightning rod) directly connected to the structure’s
primary grounding (earthing) system. Ideally the lightning rod should be mounted between approx 1,5
meter (5 feet) and 3 meter (10 feet) away from the light and be at least high enough to cover the light
completely by an angle of 30 degrees preferred (max 45 degrees), see Figure 1 - Distance between the
lightning rod and light.
The light Strobeline cable must be correctly assembled to the cable glands so that the outer screen of
the Strobeline cable is connected to the light fixture and enclosures (see 4.4 above).
The light Strobeline cable must be attached to other system enclosures (i.e. junction boxes) using the
provided EMC cable glands.
The light fixture, the light fixture mounting bracket and junction boxes and other system enclosures must
be directly connected to an earth point with a minimum 6AWG wire.
If the system is not correctly connected to the earth it may behave erratically, the system components
may be damaged, the service life of the system components significantly reduced and the warranty of
the system invalidated.

TROUBLESHOOTING
Please contact the Orga/TWR Lighting, Inc. Service Department with further information about your
problem if the following topics do not resolve the fault so that we can assist you in making your L350xxx light operational.
The photocell contains a small red alarm LED that will turn on if the light has a FAIL alarm status.
Alarm LED on photocell
Figure 9 - Photocell
7.1
LED failure
If 25 % or more of the LED’s are not working then the light will automatically turn off the LED array.
The alarm contact will be activated and the alarm LED on the photocell will be on.
The light should be replaced – follow the RMA instructions in this manual.
7.2
Wrong day/night intensity
This indicates that the system cannot determine a day or night condition. The internal controller of the
L350-864-G light continuously monitors the readings from the photocell.
If a L350-864-G light is not reading the correct ambient light level conditions then the light will default to
“always on” mode:
o
Check the position of the L350-864-G light and make sure that the photocell is not directly
shielded by nearby structures so that it is not reading the proper ambient light level. If that is
the case turn the light through 90 or 180 degrees.
o
Check the photocell condition for excessive dirt or damage.
o
Power off, wait one minute and power on again.
If the situation still occurs then the light fixture or the light engine needs to be replaced.
The light should be replaced – follow the RMA instructions in this manual.
