5.5 Segmentation and Digit Designation
In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments
. Drawing A-38532 in Appendix E details which connector pin is wired to each digit
segment and the wiring color code used throughout the display.
The electrical and signal specification
drawings in Appendix B specify the driver connectors
controlling the digits. Numbers shown in hexagons in the upper half of each digit indicate
which connector is wired to that digit.
5.6 Schematics
For advanced scoreboard troubleshooting and repair, it may be necessary to consult the
schematic drawings. Located in
Appendix D , schematic drawings show detailed power and
signal wiring diagrams of internal display components such as drivers, horn interface cards,
and transformers as well as optional components like TNMCs and radio receivers.

5.7 Suspension System Periodic Inspections
Suspension systems need to be inspected periodically. Listed below are instructions and
information about such inspections.
Static System
A static-hung system should be inspected one year after initial installation and once every
five years thereafter.

Inspect cable assemblies for broken wires, crushes, or kinks.

Inspect components, per manufacturer's recommendations, for deformations.

Inspect the four-sided scoreboard for any loose or missing bolts.

Inspect the attachment bracket for loose bolts or cracks in members or welds.

Check torque on all wire rope clips.
Hoist System
Hoist systems must be inspected annually per OSHA requirements. Some local governing
bodies require more frequent inspections. See the hoist manufacturer's manual for inspection
procedures.

Inspect cable assemblies for broken wires, crushes, or kinks.

Inspect connections for loose bolts or cracks in members or welds.
Be sure to document all inspections. Any irregularities must be addressed immediately.
For installation problems, call the original installer; for hoist problems, contact the hoist
manufacturer.
