The BFD is a large 977.9 x 482.6 mm
(38.5 x 19") LED display (128 x 64 pixel
resolution) which is driven from the
RS485 port of a G3. The BFD is built using
32 display boards in an 8 column by 4 row configuration. When used with a G303, the
BFD will display the contents of the current
G3 page. When used with larger G3s, the
desired information is selected by using a
"display primitive" on the current G3 page.
Multiple BFDs can be driven from a single G3
(see Using Multiple BFDs with a single G3).
The exact number is dependent upon the
lengths of the individual wiring runs.
The display is housed in a welded
steel enclosure and the display window
(0.118" thick red acrylic) is sealed to the
enclosure using a gasket and bezel strips.
The gasketed rear panel is bolted to the
enclosure. The ventilation slots and internal
fan are designed to provide adequate cooling
in a normal industrial environment. The enclosure is designed to hang from an
overhead support. The BFD enclosure can
be easily converted for indoor NEMA 4
operation using the optional BFD NEMA 4
conversion kit. The kit includes a sealed
cover plate (to plug the vent hole), an
external "cabinet cooler" (to replace the
internal fan) and a DIN-rail mounted power
supply to operate the "cabinet cooler".
Power to the BFD is provided by a universal
AC input power supply. The AC power and
the G3 RS485 cable enter the enclosure
through separate conduit fittings. AC
power connects to the power supply via a
removable 3 position terminal block. The
RS485 signal connects to the communication
board via either an RJ45 modular plug or
a removable 2 position terminal block.
