SECTION 2 : PRINCIPLES OF OPERATION
2.1 Power supply P/N 113742
The main power input is converted in 48VDC through the AC power supply that feeds the 2 command
cards and power cards.
2.2 Power cards P/N 113741B
The system includes 9 power cards that regulate the current sent to the 16 white led circuits and 1 red
led circuit as per figure 2-2:
-
8 power cards for white led circuits: each card regulates the current of 2 white led circuits of the
same projector during daytime and twilight;
-
1 power card that regulates the current of the 1 red led circuit during night time; the red led
circuit is in serial with 2 projectors.
Those power cards are connected to the command card through connector. The status of the
command cards and their respective led circuits are indicated by the luminous indicators D6 to D12
on the command card (figure 2-1 below). Those indicators are normally off and red blinking in case
of default.
2.3 Command cards P/N 113744L and 113744R
The 2 command cards are powered in 48V
-
First command card P/N113744L is used for day only and monitor the power cards of the 6
lower projectors. This command card is switch off during twilight and night mode
-
Second command card P/N113744R is used in day, twilight and night mode and monitor the
power cards of the 2 upper projectors
Day command card 113744L send an alarm in case more than 3 white circuits are out of order
Twilight/night command card 113744R send an alarm in case 2 circuits are out of order.
Both those command cards allow to detect the alarm of the complete system with 9 luminous
indicators described in figure 2-1,
The second command card P/N113744R allows to define through the dip-switches below
- the color during twilight/night,
- master or slave mode of the system (dipswitch n°1). Without controller or GPS, one command card
113744R must be set up in master mode and all command cards from other flashheads be in slave
mode. In case of GPS or external controller is used, all command cards must be set up in slave mode.
Note: The configuration of the 2 command cards is done in the
factory and shall not be modified by the end-user
.
Dip switches on the command card 113744R
•
Color during night time: dipswitch n°6 « on » -> red color (default setting), « off » -> white
color
•
when set-up in master mode (dipswitch n°1 on « on »), the command card P/N113744R
creates a top sync pulse indicated by D14 sent to second command card 113744L and other flash-
heads from terminal 1
