Section 1: Introduction

1.1 How to Use This Manual

This manual explains the installation, maintenance and troubleshooting of the 68mm

AF-3080 Galaxy signs. For questions regarding the safety, installation, operation, or

service of this system, please refer to the telephone numbers listed on the cover page

of this manual.

Important Safeguards:

1. Read and understand these instructions before installing.

2. Properly ground the display with a ground rod for each face at the display

location.

3. Disconnect power when servicing the display.

4. Do not modify the display structure or attach any panels or coverings to the

display without the written consent of Daktronics, Inc.

The manual contains six sections: Introduction, Mechanical Installation, Electrical

Installation, Maintenance and Troubleshooting, Appendix A, and Appendix B.

• Introduction covers the basic information needed to make the most of the

rest of this manual. Take the time to read the entire introduction as it defines

terms and explains concepts used throughout the manual.

• Mechanical Installation provides general guidance on sign mounting.

• Electrical Installation offers general guidance on terminating power and

signal cable at the sign.

• Maintenance and Troubleshooting addresses such topics as removing

basic sign components, troubleshooting the sign, performing general

maintenance, and exchanging sign components.

• Appendix A includes the drawings referenced in this manual.

• Appendix B contains information on the signal converter.

Daktronics identifies manuals by an ED number located on the cover page of each

manual. For example, Daktronics refers to this manual as ED-13620.

Daktronics, commonly uses a number of drawing types, along with the information

that each provides. This manual might not contain all these drawings:

• System Riser Diagrams: Overall system layout from control computer to

sign, power, and phase requirements.

• Shop Drawings: Fan locations, mounting information, power and signal

entrance points, and access method (front and rear).

• Schematics: Power and signal wiring for various components.

• Display Assembly: Locations of critical internal sign components, such as

power supply assemblies, controller boards, thermostats, and light detectors.

Introduction

1-1

Figure 1 below illustrates Daktronics drawing label. The lower-right corner of the

drawing contains the drawing number. The manual identifies the drawings by listing

the last set of digits and the letter preceding them. In the example below, the manual

refers to the drawing as Drawing B-181287. Appendix A contains all of the

reference drawings.

Figure 1: Drawing Label

This manual shows all references to drawing numbers, appendices, figures, or other

manuals in bold typeface, as shown below.

“Refer to Drawing B-181287 in Appendix A for the power supply location.”

Additionally, the manual lists drawings referenced in a particular section at the

beginning of that section as seen in the following example:

Reference Drawing:

Shop Drawing; VF-****-27x75-18-W............................Drawing B-181287

Daktronics builds displays for long life and that require little maintenance. However,

from time to time, certain sign components need replacing. The Replacement Parts

List in Section 4.14 provides the names and numbers of components that you may

need to order during the life of the sign. Most sign components have a white label

that lists the part number. The component part number is in the following format:

0P-_ _ _ _-_ _ _ _ (component) 0A-_ _ _ _-_ _ _ _ (multi-component assembly).

Following the Replacement Parts List is the Daktronics Exchange and Repair

and Return Programs in Section 4.15. Refer to these instructions if any sign

component needs replacement or repair.

1.2 Network Concepts

The concept of using LED displays as a cost effective, high impact method of

communication is rapidly growing throughout many industries and businesses. The

reasons for this growth are many, but the need for additional features and the

complexity of multiple display installations has emerged. Daktronics display systems

have been designed to meet those needs.

The common thread to most client requests is a means of programming and

controlling a group of displays from a central control point. Daktronics responded by

developing a powerful system of interconnecting and controlling displays. Great care

has been taken to design products that will satisfy a wide variety of installations.

Some of the design goals of these systems include the following:

• Easy transfer of messages

• The ability to tell a display or group of displays in the network which

message should run

• The ability to determine the status of any display on the network

• The ability to control multiple display technologies on the same network
