Section 1: Introduction

This manual explains the installation, maintenance and troubleshooting of the Daktronics MF­1000 Series Status/Indicator displays. For questions regarding the safety, installation,
operation, or service of this system, please refer to the telephone numbers that are listed on
the cover page of this manual.

This manual is divided into five (5) sections: Introduction, Mechanical Installation,
Electrical Installation, Maintenance and Troubleshooting, and Appendix A.

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

this manual. Take time to read the entire introduction because it defines terms and
explains concepts used throughout the manual. It also contains an overview of the
product and product safety information.

• Mechanical Installation provides general gu i dance o n display mounting.

• Electrical Installation gives general guidance on terminating power and signal

cables at the display.

• Maintenance and Troubleshooting addresses such things as removing basic display

components, troubleshooting the display, performing general maintenance and
exchanging display components.

• Appendix A lists the drawings referenced in this manual.

Daktronics identifies manuals by the ED number located on the cover page of each manual.
For example, this manual would be referred to as ED-16705.

Listed below are a number of drawing types commonly used by Daktronics, along with the
information that each is likely to provide. This manual might not contain all these drawings.
All drawings referenced in this manual will be found in Appendix A.

• Shop Drawings: Fan locations, light and temperature sensor locations, sign

dimensions, mounting information, power and signal entrance points, and access
method (side).

• System Riser Diagrams: Overall system layout from control location to the display.

• Schematics: Power wiring, signal wiring, panel board or power termination panel

assignments, signal termination panel assignments and transformer assignments.

• Assembly: Component locations and part numbers for the various circuit boards.

Figure 1 illustrates a Daktronics drawing label. The drawing number is located in

the lower-right corner of each drawing. This manual refers to drawings by listing the
last set of numbers and the letter preceding them. In the example below, the drawing
would be referred to as Drawing B-206465.

Introduction 1-1

All references to drawing numbers, appendices, figures or other manuals are
presented in bold typeface, as shown below:

“Refer to Drawing A-206465 in Appendix A for the power supply location.”

In addition, any drawings referenced within a particular section are listed at the
beginning of that section as shown in the following example:

Daktronics displays are built for long life and to require little maintenance. However,
from time to time, certain display components will need to be replaced. The
Replacement Parts List in Section 4.5 provides the names and part numbers of
components that you may need to order during the life of this display. Most display
components have a white label that lists the part number. The component part
number is in the following format: 0P-____-____ (circuit board) or 0A-____-____
(multi-component assembly).

Following the Replacement Parts List is an explanation of the Daktronics
Exchange and Repair and Return Programs. Refer to these instructions if any
display component needs replacement or repair.

1.1 Safety Precautions

Important Safeguards:

1. Read and understand these instructions before installing the

display.

2. Be sure the display is properly grounded with a grounding

electrode at the display location.

3. Disconnect power to the display when it is not in use.

4. Disconnect power when servicing the display.

5. Do not modify the display structure or attach any panels or

coverings to the display without the written consent of Daktronics,
Inc.

1.2 Network Concepts

The concept of using LED technology displays as a cost effective, high impact
method of communication is rapidly growing throughout many industries and
businesses. The common thread of most requests is the available methods of
programming or controlling the displays.

Manual Control (Switch Inputs)

The Daktronics MF Series displays are controlled manually with a switch wired to
the display. A two-position switch configuration forces the display to show either of
the two message options. A three-position switch configuration forces the display to
show either of the two message options or the display can be turned off.

1-2 Introduction

1.3 Product Overview

The MF Series Status and Lane Indicator displays are part of a family of Daktronics
LED digit displays designed for easy installation, readability, and reliability.

These displays have the following features:

• These displays use LEDs to illuminate their status or indicator.

• Power usage for individual displays in this series is a maximum 25 W. All

models have a 120 V power requireme nt .

• All MF Series displays are configured with red and green LEDs.

• MF Series cabinets are constructed of heavy-gauge alum i num.

• Digit faceplates are black and are set directly into the surface of the display.

• Mounting weights and dimensions for each model are listed in Section 2 of

this manual.

• The models are equipped with a photo sensor for automatic dimming in

changing-light environments.

1.4 Component Identification

The following terms include some of the more commonly used terms when referring
to these displays.

This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.

Circuit Board: The LEDs are mounted to a circuit board, which mounts directly to
the back of the power supply board.

LED (light emitting diode): LEDs are high-intensity, low-energy lighting units.

1.5 Daktronics Nomenclature

To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how various components are labeled in those drawings. You will find this
information useful when trying to communicate maintenance or troubleshooting
efforts.

The following labeling formats might be fou nd on va ri o us Daktronics drawings:

• “TB _ _” denotes a termination block for power or signal cable.

• “E _ _” denotes a grounding point.

• “J _ _” denotes a power or signal jack.

• “P _ _” denotes a power or signal plug for the opposite jack.
