Section 1: Introduction

This manual explains the installation and maintenance of Daktronics Tuff Sport® transparent shot clock displays. For additional information regarding the safety, installation, operation, or service of these displays, refer to the telephone numbers listed in Section 5.6. This manual is not specific to a particular installation.

Important Safeguards:

 Please read and understand all instructions before beginning the installation process.

 Do not drop control equipment or allow it to get wet.

 Do not disassemble control equipment or electronic controls of the display; failure to

follow this safeguard will make the warranty null and void.

 Disconnect display power when not in use or when servicing.

 Disconnect display power before servicing power supplies to avoid electrical shock.

Power supplies run on high voltage and may cause physical injury if touched while powered.

 Do not modify the scoreboard structure or attach any panels or coverings to the

scoreboard without the express written consent of Daktronics, Inc.

Project-specific information takes precedence over any other general information found in this manual.

1.3 Model Number

Daktronics scoreboards are differentiated by their model numbers and two-letter prefixes for each sport. Most Daktronics scoreboards also carry a two-number suffix that refers to indooroutdoor status, power supply, and digit color.

1.4 Scoreboard Controllers

Daktronics Tuff Sport transparent shot clock displays are designed for use with the All Sport® 5000 series control console. This controller uses keyboard overlays (sport inserts) to control numerous sports and scoreboard models. Refer to the following manual for operating instructions:

 All Sport 5000 Series Control Console Operation Manual (ED-11976)

This control console manual is available online at www.daktronics.com/manuals.

1.5 Product Safety Approval

Daktronics transparent shot clocks are UL-listed and tested to CSA standards (120 V AC) and CE-labeled (230 V AC) for indoor use. Contact Daktronics with any questions regarding the testing procedures.

Section 2: Specifications

The following chart details all of the mechanical specifications, circuit specifications, and power requirements for each display in this manual. Models are listed in alphanumeric order.

Note: All displays require a 120 V AC, 15 A circuit. Displays with a 230 V A C power requirement are also available.

Specifications 5

Section 3: Mechanical Installation

Mechanical installation consists of lifting and permanently mounting the shot clocks. Be sure that the installation complies with local building codes.

Note: Daktronics does not assume any liability for any installation derived from the information provided in this manual or installations designed and installed by others.

3.1 Lifting the Display

Small Daktronics scoreboards use two lifting straps that encircle the scoreboard. It is recommended to use a spreader bar with the straps.

Note: Daktronics assumes no liability for damages resulting from incorrect setup or lifting methods.

3.2 Shot Clock Mounting

BB-2140 and BB-2150 shot clocks are mounted behind and above the top center of the backboard with included hardware. Due to game play, these shot clocks will be exposed to a lot of movement and vibration. The brackets need to be designed to minimize vibration and shot clock movement.

BB-2141 and BB-2151 shot clocks are mounted on the rear of the backstop, perpendicular to the backboard with included hardware. Refer to Drawing A-184787 and Drawing A-1060357 in Appendix A for the approximate location to mount both shot clocks sizes on the backstop.

3.3 Control Enclosure Mounting

IMPORTANT: The control enclosure must be located within 30' (9.1 m) of the shot clock.

Mount on the base of the backstop with four #10 self-drilling screws. Power and signal from the control console will be routed to the enclosure.

3.4 Remote Horn Enclosure Mounting

Use two #10 self-drilling screws to mount the remote horn enclosure in an open location so that sound is able to radiate. A 20' (6.1 m) pre-attached cable is included, but this cable may be extended to mount the horn enclosure further away from the control enclosure if needed.

3.5 Camera Mounting

If a camera is to be added (BB-2140 and BB-2150 only), camera mounts accepting two inch pipe are available; only one may be used at a time. A cable tray can be used to route camera wiring down either side of the shot clock. Refer to Drawing B-249064 in Appendix A.

Note: Total weight of the camera and mounting arm cannot exceed 50 lb (23 kg). Design mounting brackets to accommodate both the shot clock and the camera.

Mechanical Installation 7

Section 4: Electrical Installation

CAUTION: Only qualified individuals should access the electrical components of the display and its associated equipment. It is the responsibility of the electrical contractor to ensure that all electrical work meets or exceeds local and national codes.

Daktronics engineering staff must approve all changes or the warranty will be void.

4.1 Installation Overview

Electrical installation involves routing power and control signal wiring through separate conduit or wire ways.

Note: Control signal cable and some junction boxes are not provided as part of this system and can be purchased locally or from Daktronics.

4.2 Power

Install a grounded receptacle near the equipment so that the power cord can easily reach it.

Each shot clock control enclosure comes with a 120 V AC or 230 V AC twist lock power plug. The power plug will need to be attached to a 120 V AC or 230 V AC power cord (by the customer) as follows:

 120 V AC wiring: Connect black wire to copper terminal, white wire to nickel

terminal, and green wire to green terminal.

 230 V AC wiring: Connect black wire to copper terminal, red wire to copper terminal,

and green wire to green terminal.

Grounding

Connect the scoreboard to earth ground. Proper grounding assures reliable equipment operation and protects the equipment against damaging electrical disturbances and lightning. Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor performing the electrical installation can verify ground resistance. Daktronics Sales and Service personnel can also provide this service. The grounding connection on the power cord‟s three-prong plug connects to the shell of the scoreboard.

Note: The customer must properly ground the outlet according to local and national codes. Failure to ground the outlet voids the warranty for the scoreboard.
