3 INSTALLATION
3.1 Device installation
Install the obstruction light to selected mounting point using quality-made fasteners. Level the light using a
spirit level (bubble level) if necessary. Tighten bolts and nuts. The light has 6 holes for M8 bolts on the
mounting plate. Photocell is located on top of the light under the glass and should have an uninterrupted
view of the sky to work correctly. There are two different size cable glands used on the device: M25 cable
glands for 6-17 mm cable diameter and M20 cable glands for 6-12 mm cable diameter. Make sure that all
unused glands or gland holes are sealed.
Figure 4: Dimensions (mm)
3.2 Wiring
Route cables using cable glands on back of the light head. Connect power cable wires securely to Power IN
terminal block connector. Power OUT terminal can be used to distribute power to the next light head.
Connect Modbus/RS-485 cable wires to Modbus/RS-485 IN/OUT connector. Use the same connector to
distribute data signals to next light head. Connect alarm relay cable wires to alarm relay connector. Lights
are easy to chain using lights’ internal connectors.

4 OPERATION
To configure the obstruction light, open the three M6 screws that secure the lower flange to the chassis
using a hex key and pull out the PCB. Using the configuration DIP switches, configure the desired
parameters into the light. The DIP switches are numbered 1-8. Embedded software in the obstruction light
reads configuration switches regularly. Configuration change becomes effective within a few seconds.
The light can be configured between two different operating modes. Light reset is needed when changing
between the modes.
Stand-alone mode: In this mode, the light operation is configured with its DIP switches. No additional
controllers are needed. Light head will use its internal photocell to determine the time of day (day, twilight or
night). The light will change its flashing mode based on photocell data and how the user has configured the
light. Light heads will synchronize their flashing with the built-in GPS module. After light head start-up, it will
take some time for the light head to acquire a GPS lock.
Modbus mode: In this mode, the light is being controlled with an additional Obelux controller. If connection
is lost to the controller, the light will keep working on its own. It will use its internal photocell and GPS to
synchronize flashing and determine the time of day. The light will return to normal operation when the
connection is recovered.

typically received from GPS and illumination information comes from photocell. If the information flow from
the master unit to slave units is interrupted, the slave units will use local photocell setting and local time in
their operations. As the data flow resumes, the slaves automatically synchronise themselves with the master
unit.
Chain the lights as shown in section 3.2.5.
Set a lamp to master mode by switching its DIP7 on. Set DIP7 off in the slave lamps to put them to slave
mode.

Set the master light to stand-alone mode and the slave lights to Modbus mode with DIP8.

Use configuration DIP switches 1-4 to give the slave lights RS-485 bus addresses. Duplicate addresses on
the same bus are not allowed. Give lights connected to the same communication bus an address starting
from one. RS-485 bus should be terminated with on-board 120 ohm resistors by turning on the termination
DIP switch on both ends of the communications bus.
In the master lights Web interface, configure:
►Data Tables -> Settings -> Slave Options
•B0: Transmit Behavior Bits
►Data Tables -> Settings -> Slave behavior
•B0: LI Red Twilight
•B1: MI Red Twilight
•B2: HI Red Twilight
•B3: LI Flash (visible)
•B4: LI Flash (IR)
►Data Tables -> Settings -> Options2:
•B2: Do not use own photocell (will use default ToD, if no master connection)
•B3: Use Default FPM if master connection lost
•B6: Transmit FPM (Master mode only)
Then reset the lamps for the settings to take effect.

4.6 Heater operation
All models have an integrated 20W heater element. The heater starts working when the light internal
temperature drops below 10°C. Heater reaches 100% operation when temperature drops below 5°C. Heater
stops working after the temperature rises above 10°C.
4.7 Causes for ALARM
The following events can cause an ALARM:
Internal hardware or power failure.
Light source failure, including decreased intensity level below rated level of light.
Loss of GPS synchronization signal or GPS module failure.
Incorrect photocell operation.
The ALARM LED will turn on and ALARM relay will activate.
4.8 On-board LEDs
Status indication LEDs are located on the controller board. Some of the status indicators have three
operating states (off, on and flashing). The lights have three status LEDs on the controller board. These
status LEDs are visible only when service access hatch is open, except the ALARM LED that can be seen
through the glass cover.

Alarm indicator (RED)
LED OFF: Normal operation, no alarms
LED ON: Active alarm condition
4.9 GPS operation
In stand-alone mode, light heads will automatically synchronize their flashing with their built-in GPS module.
After light head start-up, it will take some time for the light head to acquire a GPS lock, because the lights
need a signal from multiple GPS satellites. The GPS provides same timing information for all the lights, so
they will flash in sync.
4.10 Troubleshooting
The light doesn´t start
•No power (check that the POWER status LED is illuminated).
•Incorrect configuration (check DIP switches, make sure Test mode is turned off).
•Loose wires (check that all wires are properly seated in terminal block connectors).
•Do not exceed maximum operating voltage. Mains power supply input is protected with overvoltage
protection circuit that is tuned to stated operating voltage range.
No Modbus data connection to Obelux controller
•Check DIP settings. Check that light has a correct Modbus address and that there are no conflicting
addresses. Make sure the light is configured to Modbus mode (DIP8).
