Drawing A-69945. Reference drawings are grouped and inserted in alphanumeric order in Appendix A. The serial and model number of a Daktronics scoreboard can be found on the ID label, located on the display. This label will be similar to the one shown in Figure 2.
Page 6: Manual Overview
If a component fails, Daktronics sends the customer a reconditioned replacement within 24 hours. The customer, in turn, sends the failed component to Daktronics. This not only saves money but also decreases scoreboard downtime. This service is provided to qualified customers who follow the program guidelines explained below.
Page 7 If the defective equipment is not shipped to Daktronics within 30 working days from the invoice date, it is assumed you are purchasing the replacement part, and you will be invoiced for it. This second invoice represents the difference between the exchange price and the full purchase price of the equipment.

Page 24: Lifting The Scoreboard
The columns and footings and all connection details must be designed and certified by a professional engineer licensed to practice in the state in which scoreboard will be installed. Daktronics does not assume any liability for any installation derived from the information and drawings provided in this manual or designed and installed by others.
Page 25: Scoreboard Mounting
If you must use this method, ensure a minimum angle between the chain and scoreboard of at least 45°. Note: Daktronics assumes no liability for scoreboard damage resulting from incorrect setup or incorrect lifting methods.

Page 27: Ad Panel Mounting
Models BA-515 and BA-518 Ad panels are mounted directly to the scoreboard for models BA-515 and BA-518. Refer to Drawings A-52585 and A-52811 for mounting details.
Page 29: Electrical Installation
Refer to the chart in Section 3 to determine circuit specifications and maximum power requirements for the models described in this manual. Daktronics outdoor scoreboards have been designed for easy access to components, and the power and control signal hookup has been simplified. Front panels are removable to allow access to the digits, cabling and other electronic components.
Page 30: Power Installation
Power Installation There are two basic considerations for power installation: installation with ground and neutral conductors provided, and installation with only a neutral conductor provided. These two power installations differ slightly, as described in the following paragraphs: Installation with Ground and Neutral Conductors Provided For this type of installation, the power cable must contain an isolated earth-ground conductor.
Page 31: Power And Signal Connection
The scoreboard must be connected to earth ground. Proper grounding is necessary for reliable equipment operation. It also serves to provide protection to the equipment against damaging electrical disturbances and lightning. Failure to adhere to the following grounding methods will void the warranty.
Page 33: Digit Maintenance And Troubleshooting
Section 8: Digit Maintenance and Troubleshooting IMPORTANT NOTES: 1. Disconnect power before doing any repair or maintenance work on the scoreboard! 2. Allow only qualified service personnel access to internal display electronics. 3. Disconnect power when not using the scoreboard. For assistance in the maintenance of the optional message center, refer to the manual that accompanies the message center or to Section 9 in this manual.
Page 34: Lamp Replacement
Reference Drawing: Digit Service .................... Drawing A-27674 The primary service required for Daktronics baseball scoreboards is to periodically replace bad lamps. Refer to the table in Section 3 to determine the wattage of the lamps the scoreboard uses. Refer to Section 8.8 to determine the part numbers.
Page 35: Fuses
Fuses Reference Drawings: Layout, 16 Column Driver III ..............Drawing A-123940 Layout, 8 Column Driver III ..............Drawing A-123941 The digit lamp driver has 17 fuses. There is one fuse to protect each digit circuit. F1 through F16 are located near each output connector under the driver’s metal cover. The lamp driver’s other fuse, F17 protects the driver’s logic circuit and fan.

Page 39: Team Name Message Centers Maintenance And Troubleshooting
Operating the display with dirty fan filters or without fan filters will void the warranty. 5. Daktronics product managers or engineering staff must approve any changes that may affect the weather-tightness of the display. This is to include, but is not limited to, border shrouding, back sheets, cooling fans, fan filter and filler panels.

Service Procedures Reference Drawings: Lens Removal, Front Access..............Drawing A-99898 Lens Assy Removal, Front Access ............Drawing A-99899 Correct Lens Position, 1-1/2" ..............Drawing A-75204 Removing a Module For many maintenance or repair procedures, the first step is to remove a module. Each 8x16 lens assembly is secured to the frame by two spring-loaded latches, one on each side.
Page 41: Replacing A Lampbank
A 3.58 W lamp is positioned behind each lens. Use the controller lamp test to locate bad lamps. Refer to Section 9.14 for the part numbers of replacement lamps and lenses. Daktronics-approved 3.58 W lamps have an estimated life of 17,000 hours if operated at 11.0 V. Always use Daktronics-approved lamps.
Page 42: Individual Lamp Replacement
1. Remove the defective lamp using the lamp-extracting tool. 2. Replace defective lamps with Daktronics approved lamps of the same wattage. Refer to Section 9.14 for the correct replacement lamps. 3. Noting proper lens orientation, snap the lens back into the lens/reflector assembly (refer to Section 9.4).
Page 43: Louver Maintenance
If a filter media shows evidence of damage or wear, replace the filter with a Daktronics filter. If a filter other than the Daktronics standard filter is used, follow these criteria (refer to Section 9.14 for the part number of the filter): 1.
Page 44: Filter Removal
Once the filters have been replaced, turn power back on. Make sure that the fans are turning properly. Note: Turn the power OFF after checking the fans. Periodically check airflow through the lenses to ensure that there are no obstructions in the lens exhaust holes.
Page 45: Lens Airflow
2. Spin the fan blades with a pen or pencil to ensure that the bearings are free and the fan is still in balance. After 10 percent of the fans have been replaced, Daktronics recommends replacing all fans to reduce associated maintenance costs that may incur with increased heat buildup from fan failure.
Page 46: Structural Inspection
9.11 Structural Inspection Perform a visual inspection annually. Check the paint and look for possible corrosion, especially at footings, structural tie points, and ground rods. Fasteners should be checked and tightened or replaced as required. At least once a year, check the inside of the display for signs of water intrusion (for example, water stain marks).

Page 143 Eyebolts Almost every display that leaves Daktronics is equipped with eyebolts for lifting the display. There are two standard sizes of eyebolts: ½″ and A″. Load Increase Factor: The load increases as the lift angle (θ) decreases. The allowable load on the eyebolts also decreases with the lift angle due the bending stress on the eyebolts.
Page 144 F. Eyebolts should never be painted or otherwise coated when used for lifting. Such coatings may cover potential flaws in the eyebolt. G. To attain the safe working loads listed for regular eyebolts, 90% of the thread length must be engaged. Copyright 1996-2001 ED-7244 Daktronics, Inc. Rev. 4 – 14 March 2001...
