Modules
A module is a replaceable unit
consisting of a display panel with
clusters of LEDs, called pixels. The
pixels display messages on the
display. Refer to Figure 3 and
Figure 2 .
Each module contains drive
electronics that receive data
packets from the Vanguard
®
control
board and lights the appropriate
pixels at the correct dimming level.
Power Supply Groups
Power Supplies
The power supplies mount to internal cabinet verticals.
The power supplies provide power to the modules. Multiple power supplies provide
power redundancy. Each power supply is paired with another power supply to make a
power supply group. If one power supply in the group fails, the other supports the full
power load, preventing power failure to the modules.
Isolation Board
One isolation board mounts to each power
supply. The isolation board provides input and
output voltage to the power supply. Figure 5
shows an isolation board. The isolation board
receives 120 VAC input voltage from the
distribution panel. Output from the power supply
routes through the isolation board. From there,
the 24 VDC output routes to the DC breaker rail.
Low Voltage Distribution Board
One low voltage distribution board (LVDB)
mounts to each power supply. The (LVDB)
provides input and output voltage to the power
supply. Figure 4 shows an LVDB.
The LVDB receives 120 VAC input voltage from
the distribution panel. Output from the power
supply routes through the LVDB. Each output is
fused at 15 A with automotive spade fuses. From
there, the 24 VDC output routes to the modules.
LVDB diagnostics include power supply data sent
to the VFC-3000 controller about output voltage
and the passing or failing of each fuse.
