3.4.1
LED signs
Mechanical structure
The housing of the LED signs consist of black-coated aluminium
profiles. The front profile frame with included viewing window can
be opened to the left. A securing rod is used to secure the opened
profile frame. Are the LED signs more wide than high, they can be
folded upwards.(Exceeding a certain size gas springs are used for
support). All LED signs are equipped with a deflector which is
mounted over the sign. The single VarioSign
LED-tiles are fastened in the rear part of the profile frame on a
support plate. The control electronics are located in an external
housing on the rear side of the LED signs.
Electric function
An LED matrix sign always requires a corresponding number
(depending on the model) of VarioSign LED circuit boards, bus
distributors and NiBus master circuit boards for controlling them. A
NiBus master circuit board can control several VarioSign LED tiles
with the bus distributor. The NiBus master circuit boards are
adjusted with dip switches in accordance with their position in the
sign. The communication with the remote control, the memory stick
and other signs is always processed by NiBus master circuit board
1. The image files are stored on a memory stick; this stick can be
plugged directly onto the NiBus master circuit board. The NiBus
master circuit boards are located in external control housings on the
rear of the LED signs.
