projector includes 1 red LED circuit and 1 red LED circuit in series with 2 other projectors. There are connected to the stainless steel
supply which contains:
- 1 power card for the 2 red led circuits
- a command card with 10 luminous indicators and 8 dipswitchs used for the setting of the system
- a test button to force day mode or night mode
- a 230Vac surge protection
- a terminal connection for the 48Vdc input power, day/night information (0V=day mode, +48Vdc=night mode), alarm and optional
external top sync (24V-to-48V pulse) coming from other light or gps interface for the synchronization with other lights
1.2.2 Cabinet OFP-CAB-6P-1E-RW-240-U
The cabinet consists:
- 1 power supplies, surge protection
- terminal blocks for wiring to the flash-head, external photocell, remote alarms, etc…
- A S2 button with 3 positions
- “Remote” position, the lights are in normal operation

2.2.3 Ambient Light Sensor P/N100755 (photocell)
If included, the ambient light sensor should be mounted upright, away from artificial light (such as floodlights), and in a location that will
enable its sensor window to have an unobstructed view of the polar sky (eg., pointed north in the northern hemisphere).
The photocell 48VDC returns 0V during day time and +48Vdc close in darkness
Input voltage 48VDC +15/-10%
Output voltage 48VDC +15/-10% (night time), 0V (day time)
2.2.4 Wireless synchronization with P/N113746 (DIN rail mounting inside power cabinet)
If included, the GPS interface comes with an external magnetic antenna. The cable of the antenna is to be connected in the GPS interface
with a jack plug

Section 3 : Principles of operation
The flash-head is powered in 48VDC+15%/-10% from an obsta power supply or any external DC power supply providing sufficient
power for the light.
3.1 Power cards
The power cards regulate the current of 2 led circuits. Each power card is connected to the command card on one side and 2 negative poles
of 2 led circuits. Positive poles of all led circuits are connected together
There are 6 power cards that control the current of 12 white LED circuits (negative poles are blue and white wires from each projector) and
1 power card that controls the current of 2 red led circuits (negative pole is yellow from each projector)
3.2 Command card
The command card is powered in 48VDC and monitors the power cards, set up the configuration of the light through dipswitch
(master/slave configuration, L-865/L-864 or L-865 or L-864) and in the event of failure, send back an alarm,
L-865/L- 864 dual
color flash- head
setting can be changed

OBSTA

through the dipswitches 4, 5 and 6 from dual color to white only or red only
D6 to D15 luminous indicators on the command card:
• D6 à D12 close to WHITE#1 to WHITE#6 & RED#1 : normally off and red blinking in case of default of power card
or 1 led circuit
• D15 : normally green, off in case of alarm activated
• when set-up in master mode (dipswitch n°1 on « on »), the command card creates a top sync pulse indicated by D14
and that can be sent for other flash-heads from terminal 1
• when set-up in slave mode (dipswitch n°1 on « off»), the command card waits for a top sync pulse on terminal 3, D14
also blink at the same frequency
• If no pulse is received from terminal 3, D14 is off and light flashes on its own at 15 fl per minute as per D13
Warning: In case changing master/slave dipswitch n°1 position, do not forget to change the position on the terminal
connection 1 to/from 3 of the pulse wire accordingly

3.3 GPS P/N113746 (OPTION)
When GPS is synchronized with the satellites, 2 red and green luminous indicators indicate the status of the signal from satellite
Green led:
- the green indicator blinks: this indicates gps received signal from the satellite and a pulse is sent to the command card.
- the green indicator is off: this indicates gps do not received signal and no pulse is sent to the command card.
red led:
- the red indicator is “off” indicate day time
- the red indicator is “on” indicate night time or no signal from satellite,
When the GPS is synchronized, the top sync pulse (and 0/48VDC day/night signal if used) is sent to the command card. In
absence of signal received from the GPS (no satellite), no pulse is sent to the command card that flashes at 15 fl per minute (D13
blink at 15fl per minute and D14 is off).

4.2 Troubleshoot - malfunction
Action Solution
Voltage indicator is off Check input voltage, surge protection and switch.
Otherwise check DC is present on the 2 power
supplies output (green indicator on it should be
lighted) and/or fuse is OK
Replace the defective parts if
necessary (surge protection,
fuse or power supply)
The system is permanently
white flashing or red
Check that S2 is on « Remote » position
Otherwise masks the window of the photocell to
check day/night switch and check the wiring
connection from photocell to command card
according to the wiring diagram
Replace photocell or command
card if necessary,
Some luminous indicators D6
to D12 are blinking red in day
and/or night mode
Check the wiring connection on the related power
card. Otherwise check the power cards and the
projector following procedure (*) below
Replace power card or/and the
related projector if necessary
all indicators D6 to D11 during
day time are blinking red
Check the wire cross section of the dc cable feeding
the flashhead or check that your power supply is
sufficient enough to feed the flashhead
Replace cable or/and power
supply if necessary
D13 blinks and D14 is off,
flash rate is at 15 fl per minute
Check the wiring of the GPS, the position of its
antenna and its wire connection.
Replace GPS module if
necessary
Contact the manufacturer if necessary
* Procedure to test the power cards and the projectors:
The following procedure requires not to switch off the incoming 48VDC power supply to the flashhead
Note : FAA requires that if 25% of light output is off in one azimuth, the entire light should be switch off even if some led
circuits remain OK:
- So in white mode, if more than 3 white led circuits out of the 12 white led circuits is out of work, the command card
normally switch off the entire flashhead
- And in red mode, if 1 out of the 2 red led circuits is out of work, the command card will also switch off the second red led
circuit and switch on the white night mode (2000 candelas)

OBSTA
2 rue Troyon 92316 Sèvres Cedex FRANCE
www.obsta.com
Page
18/18
If more than 3 led circuits are out of work, the entire flashhead is off due however the 4-6 red indicators D6 to D12 still
blink and almost 1-3 power card/ projector need to be changed before light turns back to on
- Default of white led circuits: one or more indicators D6, D7 D11 is/are blinking red and some projectors are not
working in white
example: if luminous indicator D7 (or WHITE#2) is red blinking, disconnect the related green terminal of 2 led circuits and
plug it to the next power card close to it for example D8 (or WHITE#3) that is OK:
- If the luminous indicator D8 does blink also, the projector is defective and has to be changed
- If the luminous indicator D8 does not blink, the projector is ok but the power card of WHITE#2 is defective and has to be
changed
- Default of red led circuits: D12 is blinking red: 3 or 6 projectors are not working in red
- If the 6 projectors are not working in red, change the power card or use a good power card taken from one of the 6 white
circuits and connect it to “red#1”). If still the 6 projectors do not work, it means that almost 2 projectors on each red led
circuit are defective. It is possible to connect 2 red projectors in serial instead of 3 on the power card #red1, test all
projectors 2 by 2 to identify the 2 defective ones
- If 3 projectors are not working, disconnect the defective circuit on the green connector of the power card #red1 and
connect it to the second green connector of the same power card #red1: If the 3 projectors are ok, change the power card
otherwise identify which projector out of the 3 projectors is not working : connect 2 projectors in serial instead of 3 until
finding the defective one
Warning: never test a good led circuit on a defective power card, this can destroy the leds, always test led circuit on a
good power card!!
Warning: never test a red led circuit on a power card connected to the white led circuit in day mode, the current will
be too high and may destroy the red leds!!
