Section 1: Introduction
This manual explains the installation of Daktronics Single-Section Outdoor Generation III
LED Scoreboards and provides details for display maintenance. With questions regarding
the safety, installation, operation, or service of these systems, contact Daktronics. Daktronics
Customer Service telephone number is listed in Section 8.9 of this manual.
1.1 How To Use This Manual
Important Safeguards:
1. Read and understand these instructions before installing the display.
2. Do not drop the control console or allow it to get wet.
3. Properly ground the scoreboard with a grounding electrode at the
scoreboard location.
4. Disconnect power when the scoreboard is not in use.
5. Disconnect power when servicing the scoreboard.
6. Do not modify the scoreboard structure or attach any panels or coverings to
the scoreboard without the express written consent of Daktronics, Inc.
Figure 1 illustrates the Daktronics drawing numbering system. Daktronics identifies
individual engineering drawings by their drawing number (7087-P08A-69945 in the
example), which is located in the lower right corner of the drawing. This manual
refers to drawings by their last set of numbers and the letter preceding them. The
example would be Drawing A-69945.
Reference drawings are grouped and inserted in alphanumeric order in the
Appendix A: Reference Drawings.
Listed below are drawing types commonly used by Daktronics, along with the
information that each provides.
Figure 1: Daktronics Drawing Label
 System riser diagrams: overall system layout from control room to
display, power and phase requirements
 Shop drawings: fan locations, transformer locations, mounting
information, power and signal entrance points and access method (front or
rear)
Introduction 1-1

 Schematics: power wiring, signal wiring, panelboard or power termination
panel assignments, signal termination panel assignments and transformer
assignments
 Final assembly: component locations, part numbers, display dimensions
and assembly/disassembly instructions
All references to drawing numbers, appendices, figures, or other manuals are
presented in bold typeface, as in this example: “Refer to Drawing A-69945 for the
location of the driver enclosure.” Additionally, any drawings referenced within a
particular subsection are listed at the beginning of that subsection in the following
manner:

Daktronics identifies manuals by their engineering document (ED) number, which is
located on the cover page of the manual. For example, this manual would be referred
to as ED-13770.
The serial and model numbers of a Daktronics scoreboard can be found on the ID
label on the display. The label will be similar to the one shown in Figure 2. When
calling Daktronics Customer Service, please have this information available to
ensure quick service. For future reference, note the scoreboard model number, serial
number and installation date on the second page of this manual.

Daktronics displays are built for long life and require little maintenance. However,
from time to time, certain display components will have to be replaced. The
Replacement Parts List in Section 8.7 provides the names and part numbers of
components that may require replacement during the life of this display.
Following the Replacement Parts List is an explanation of Daktronics exchange and
repair and return programs. Refer to these instructions if replacing or repairing any
display component.

Introduction 1-3
1.2 Daktronics Nomenclature
To fully understand Daktronics drawings, it is necessary to know how various
components are labeled in drawings. This information is useful when trying to
communicate maintenance or troubleshooting efforts.
The label “A” on a drawing item typically denotes an assembly. An assembly can be
a single circuit board or a collection of components that function together, usually
mounted on a single plate or in a single enclosure.
In addition, the following labeling formats might be found on various Daktronics
drawings:
 “TB _ _” denotes a termination block for power or signal cable.
 “F _ _” denotes a fuse.
 “E _ _” denotes a grounding point.
 “J _ _” denotes a power or signal jack.
 “P _ _” denotes a power or signal plug for the opposite jack.
Finally, Daktronics part numbers are commonly found on drawings. Those part
numbers can be used when requesting replacement parts from Daktronics Customer
Service. Take note of the following part number formats. (Not all possible formats
are listed here.)
 “0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver
board.
 “0A-_ _ _ _ - _ _ _ _” denotes an assembly, such as a circuit board and the
plate or bracket to which it is mounted. A collection of circuit boards
working as a single unit may also carry an assembly label.
 “W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true for
ribbon cables.
 “F- _ _ _ _ ” denotes a fuse.
 “T- _ _ _ _ ” denotes a transformer.
 “PR- _ _ _ _ _ - _” denotes a specially ordered part.
 “M- _ _ _ ” denotes a metal part, and “0S-_ _ _ _ _ _” typically denotes a
fabricated metal assembly.
1.3 Manual Overview
This manual details outdoor, single-section scoreboards with LED digits and
characters. It is divided into the following sections:
Section 1: Provides an overview of the product, product safety
information and labeling and numbering descriptions.
Section 2: Lists the drawing or drawings needed to determine scoreboard
model numbers.
Section 3: Contains tables that show all of the mechanical specifications,
circuit specifications and power requirements for each model.
