Specifications 5

Figure 4: Lifting Methods

Section 3: Mechanical Installation

Mechanical installation consists of installing concrete footing and steel beams and mounting the scoreboard and accompanying ad panels to the beams.

3.1 Footings & Beams

Drawing B-268714 in Appendix A shows the recommended number of beams and spacing between them.

The column and footing size dimensions are to assist with estimating installation costs. They are estimates only and are not intended for actual construction purposes. Be sure that the installation complies with local building codes and is suitable for the particular soil and wind conditions. The columns, footings, and all connection details must be designed and certified by a professional engineer licensed to practice in the state of the installation.

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.

3.2 Lifting the Scoreboard

Larger scoreboard sections and message centers are shipped equipped with eyebolts used to lift them. The eyebolts are located along the top of the cabinet for each scoreboard section. Daktronics scoreboards use 1/2" and 5/8" shoulder-type eyebolts mounted to a 1/8" aluminum plate or steel nut plate.

Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display. Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.

Figure 4 illustrates the preferred scoreboard lifting method on the left and an acceptable alternative lifting method on the right. When lifting the display:

 Use a spreader bar if possible.  Use every lifting point provided.

Mechanical Installation 7

Figure 5: Eyebolt Plane Load

Cables and chains attached to the eyebolts and directly to a center lifting point, as shown in the right-hand example in Figure 4, can create a dangerous lateral force on the eyebolts and may cause the eyebolts to fail. The smaller the angle between the cable and the top of the display, the lighter the sign must be to safely lift it. If this method must be used, ensure a minimum angle between the chain and scoreboard of at least 45 degrees.

Do NOT attempt to lift the display if the angle is less than 45 degrees. Exceeding load angles or weight limits could cause the bolts in the scoreboard cabinet to buckle, resulting in serious damage to the scoreboard or injury to personnel. Also, loads should be applied directly in the plane of the eyebolt as shown in Figure 5.

Note: Daktronics assumes no liability for damages resulting from incorrect setup or lifting methods. Eyebolts are intended for lifting only. Do not attempt to permanently support the display by the eyebolts.

If installers remove the eyebolts, plug the holes with bolts and the rubber washers that are used with the eyebolts. Apply silicone or another waterproof sealant to the eyebolt openings. Also inspect the top and sides of the display for any other holes or openings that may allow moisture to enter the display and plug and seal those openings.

3.3 Scoreboard Mounting

In typical multi-section installations, the lower scoreboard is installed first and secured to the support beams. The next section is then placed atop or above the lower section and attached to the beams. There are cables extending from the top of the lower sections. Guide these cables into the holes in the bottom of the upper sections for later connection.

Note: Refer to Section 4.5 for more information on the power/signal connections between sections.

The CR-2004 scoreboard is typically mounted in one of two ways:

1) clamped to vertical beams using mounting angles and long, threaded rods

2) permanently welded to tubular horizontal supports.

8 Mechanical Installation

Figure 6: C-channel Mounting Method, Side View

Clamping to Verticals

An inverted channel mounting installation uses C-channels; clip angles; 1/2-13" threaded rods; and 1/2" square nuts, hex nuts, lock washers, and optional spacers. Refer to Figure 6 and Drawing A-55101 in Appendix A.

Mount the scoreboard as follows:

1. Place the C-channel against the upper and lower rear flanges of the scoreboard.

2. Use the width of the beam to determine the appropriate hole combination to use for

the bolts. The bolts should be kept as close to the beam as possible.

3. With the C-channel as a template, use a

rear flanges of the scoreboard cabinet where the bolts will pass through.

4. Place the

/2" square nuts inside the C-channel and thread the 1/2-13" rods through

the C-channel, rear flange of the scoreboard cabinet, and spacer (if used).

5. Lift the scoreboard into position with the bolts still in place. Position the scoreboard

at the front of the beams with the threaded rods extending from the rear flanges.

6. With the threaded rod straddling the beams, place mounting angles over each pair of

bolts and secure with 1/2" lock washers and hex nuts.

7. Make final adjustments in the positioning of the scoreboard.

8. Make sure that the threaded rods are perpendicular to the scoreboard, and tighten all

of the 1/2" hex nuts.

Mechanical Installation 9

Figure 7: Scoreboard Mounting Detail, Side View

Welding to Horizontals

Steel clip angles are first bolted to the back of each scoreboard section. These clip angles are then welded on three sides to a horizontal tube, which itself has been welded to the support beams. Refer to Drawing B-268714 in Appendix A for suggested horizontal tube spacing.

Figure 7 and Drawing A-83301 illustrate the mounting of the display to horizontal tubing.

1. Visually check the display structure before beginning the installation process.

 Ensure that the structure will provide a straight and square mounting frame for

the scoreboard/display.

 Check to ensure the mounting frame will not give way at unsupported points

after the scoreboard/display is mounted. If any problems are noted, take corrective action immediately.

2. Bolt the clip angles to the rear of the scoreboard sections with ½" hardware.

Drawing B-238471 shows recommended clip angle locations. Refer to projectspecific shop drawings for exact locations of the clip angles.

3. Lift the display section into position. Refer to Section 3.2.

4. Adjust the clip angles as needed so that they are firmly against the horizontal tube.

During the installation of the first section, carefully monitor the horizontal and vertical straightness of the display. If the mounting structure does not provide a straight or square mounting surface, it will be necessary to place shims between the display section and the mounting surface to ensure straightness.

5. Weld the three edges of each clip angle that are in contact with the horizontal tube.

10 Mechanical Installation

Figure 8: Ad Panel Mounting with C-channel, Side View

3.4 Ad Panel Mounting

The installation uses C-channels; clip angles; 1/2-13" threaded rods; and 1/2" square nuts, hex nuts, lock washers, and optional spacers similar to the clamping mounting method above. Refer to Figure 8 and Drawing A-52187 in Appendix A.

Mount the ad panel(s) as follows:

1. Use the width of the beam to determine which hole combination to use for the bolts.

Be sure to keep the bolts as close to the beam as possible.

2. Using the clip angle as a template, use a

/16" bit to drill holes in the upper and lower

rear flange of the ad panel where the C-channel supports will be placed.

3. Position the C-channel inside the ad panel cabinet along the upper and lower rear

flanges as shown in Figure 8.

4. Place

/2" square nuts inside the channel and thread the 1/2-13" rods through the

C-channel, rear flange of the ad panel, and spacer (if used).

5. Lift the ad panel into position with the rods still in place.

6. With the threaded rod straddling the beams, place mounting angles over the ends of

each pair of bolts and secure with 1/2" lock washers and hex nuts.

7. Make final adjustments in the positioning of the ad panel.

8. Make sure that the threaded rods are perpendicular to the ad panel, and tighten all of

the 1/2" hex nuts.

Some ad panels have back sheets that must be removed before the display can be installed. After marking and drilling holes in the upper and lower rear flanges of the ad panel, remove the back sheets above and below the hole locations. Position the C-channel inside the cabinet and attach the square nuts to the threaded rods as described above. Be sure to replace the back sheets after placing the square nuts inside the channel and threading the rods through the holes in both the upper and lower rear flanges.

Mechanical Installation 11

3.5 Scoreboard Protective Devices

Daktronics makes optional protective devices, including screens and netting, to help prevent damage to the scoreboard due to normal ball impacts.

Note: Some users install devices to protect the scoreboard from projectiles. Scoreboard protection devices not provided by Daktronics must be approved by Daktronics prior to installation. Failure to follow this approval procedure will void the scoreboard warranty.

14 Electrical Installation

4.2 Power

Correct power installation is imperative for proper display operation. The subsections that follow give details of display power installation. Only qualified individuals should attempt to complete the electrical installation; untrained personnel should not attempt to install these displays or any of the electrical components. Improper installation could result in serious damage to the equipment or injury to personnel.

The scoreboards in this manual require a dedicated 240 V or 120 V circuit for incoming power (refer to the Specifications in Section 2).

WARNING: It is critical that 120 V scoreboard circuits be fused at 15 A and that all conductors used must be designed to pass a 15 A current in normal operation. For 240 V scoreboards, consult local electrical codes. Failure to meet wiring and overcurrent protection device requirements will void the scoreboard warranty.

Grounding

The display must be properly grounded according to local and national codes or the warranty will be void. Proper grounding is necessary for reliable equipment operation and protects the equipment from damaging destructive 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 display system must be earth-ground. The material for an earth-ground electrode differs from region to region and may vary according to conditions present at the site. Consult local and national electrical codes.

Daktronics does not recommend using the support structure as an earth-ground electrode; concrete, primer, corrosion, and other factors make the support structure a poor ground.

Note: The support structure may be used as an earth-ground electrode only if designed to do so. A qualified inspector must approve the support structure and grounding methods.

There are two types of 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 circuit must contain an isolated earth-ground conductor. In this circumstance, do not connect neutral to ground at the disconnect or at the display as this would violate electrical codes and void the warranty.

Use a disconnect so that all ungrounded lines can be disconnected. The National Electrical Code requires the use of a lockable power disconnect within sight of or at the display.

Electrical Installation 15

Figure 11: Power Warning Label

Installation with Only a Neutral Conductor Provided

Installations where no grounding conductor is provided must comply with Article 250-32 of the National Electrical Code. If the installation in question meets all of the requirements of Article 250-32, the following guidelines must be observed:

 Connect the grounding electrode cable at the local disconnect, never at the display

driver/power enclosure.

 Use a disconnect that opens all of the ungrounded phase conductors.

Connection

Power cabling is routed into the scoreboard from the rear through plastic plugs for conduit connection. If no conduit knockouts are available, installers will have to drill holes into the back sheet of the scoreboard to allow entrance of power wires.

All power wiring terminates at the enclosure shown in Figure 12, located in the lower-right corner of the scoreboard (when viewed from the front). Refer to Drawing A-327249 in

Appendix A for precise power termination location.

1. Route the power cables via conduit into rear of

scoreboard.

2. Look for a warning label similar to Figure 11 to

locate the appropriate access panel to the power breaker enclosure.

3. Loosen the screws or latches to open the access panel.

4. Route the power cables up through the bottom of the power enclosure.

5. Use a Philips screwdriver to loosen the two screws, and then lift the enclosure cover

up and off the keyholes.

6. Connect the power cables as follows:

 Neutral (white) wire to NEUT.  Live wire to LINE 1 (black)  Live wire to LINE 2 (red) – 120 V installations only  Ground wire (green/yellow) to the grounding buss bar, E41

7. Reattach the metal enclosure cover and secure the access panel.

Note: If a power receptacle is needed to operate the control console at the scoreboard for

troubleshooting, Daktronics recommends that an installation electrician provides a 240 or 120 V outlet close to the disconnect box specifically for this purpose.

16 Electrical Installation

Figure 12: Power Enclosures w/ Covers Removed (240 V & 120 V)

Figure 13: Digit Segment POST

4.3 Power-On Self-Test (POST)

The scoreboard performs a self-test each time that power is turned on and the control console is powered off or not attached to the scoreboard. If the control console is attached and powered on, the self-test does not run, and data from the control console is displayed on the scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending on the scoreboard model, the number of drivers and types of digits. Figure 13 shows an example of the LED bar test pattern that each digit performs.

Electrical Installation 17

Figure 14: Signal Enclosure w/ Cover Removed

Radio Settings

If a radio receiver is installed, the radio Broadcast and Channel settings will be displayed in on the scoreboard during the POST. These values must match the settings in the control console (refer to the manual listed in Section 1.4). Refer to Section 5.6 for more information on radio installations.

4.4 Signal Connection

Signal cabling is routed into the scoreboard from the rear through plastic plugs for conduit connection. If no conduit knockouts are available, installers will have to drill holes into the back sheet of the scoreboard to allow entrance of power wires. Note that systems with radio control do not require external signal wiring to the display.

All signal wiring terminates at the enclosure shown in Figure 14, located in the lower-right corner of the scoreboard (when viewed from the front). Refer to Drawing A-327249 in Appendix A for precise signal termination location.

1. Route the signal cables via conduit into

rear of scoreboard.

2. Look for a warning label similar to Figure 11 to locate the appropriate access panel

to the signal enclosure.

3. Loosen the screws or latches to open the access panel.

4. Route the signal cables up through the bottom of the signal enclosure.

5. Use a Philips screwdriver to loosen the two screws, and then lift the enclosure cover

up and off the keyholes.

6. At the SIGNAL IN terminal block, connect the signal cables as follows:

 Red signal wire to positive (+) terminal  Black signal wire to negative (-) terminal  Silver wire to SHIELD terminal

7. Reattach the metal enclosure cover and secure the access panel.

8. At the control location, connect a 9-pin female to 25-pin male cable (Daktronics part #

W-1249) between the J6 jack on the back of the All Sport 5000 and an available serial (COM) port on the cricket scoring computer.

Note: Refer to Appendix B for more information on setting up the TCS software.

9. For wired setups, also connect a signal cord from the J-box into jack J1, J2, or J3 on the

back of the All Sport 5000 controller.

For signal cable, Daktronics recommends, as a minimum, single-pair, shielded cable, 22 AWG (Daktronics part number W-1077). Two-pair shielded cable (part W-1234) is preferred.

18 Electrical Installation

Fiber Optic

Another common signal communication method is fiber optic cabling. A minimum cabling of multi-mode, 62.5/125 um, and 2-core fiber cable is recommended (Daktronics part number W-1242). In such installations, the signal enclosure shown in Figure 14 will be replaced by a fiber J-box. This method also requires a signal converter between the All Sport console‟s scoreboard output and the fiber optic cable (not provided by Daktronics).

4.5 Power/Signal Connections Between Sections

Refer to Drawing B-236615 in Appendix A for exact driver and power/signal interconnect cable locations.

1. On the lowest scoreboard section, open the appropriate access panel to locate the

bundle of interconnect cable coming from the driver.

Note: Additional panels may be opened for easier access when routing the cable.

2. Route the interconnect cable through the hole in the top of the lower cabinet up into

the hole in the bottom of the upper cabinet, and connect the J43 jack to the mating P43 plug coming off of one of the drivers.

3. Repeat steps 1-2 to connect the remaining scoreboard sections.

4.6 Lightning Protection

The use of a disconnect near the scoreboard to completely cut all current-carrying lines significantly protects the circuits against lightning damage. In order for this system to provide protection, the power must be disconnected when the scoreboard is not in use.

The control console should also be disconnected from power and from the signal junction box

when the system is not in use. The same surges that may damage the scoreboard‟s driver can also damage the console‟s circuitry.

9. Close and secure the digit panel, then power up and test the scoreboard to see if

changing the driver has resolved the problem.

Setting the Driver Address

Since the same LED drivers can be used for many scoreboard models, each driver must be set to receive the correct signal input, or address, for the model being used. Addresses are set through the S1 dip switch on the driver (Figure 19) using a pen or small, pointed object.

Refer to the specifications table in Section 2 to determine the correct address setting of the driver(s) in a particular scoreboard model and see Drawing A-290261 in Appendix A for addressing information for driver addresses 1 – 128.

Another method of setting the driver address using the J19 address plug is available. This address is set with jumper wires in a 12-pin plug which mates with a jack on the driver. Refer to Drawing A-115078 for a listing of the wire/pin connections for driver addresses 1 – 128. When using an address plug, it will not be possible to set the address with the S1 dip switch.

5.6 Radio Connections

To determine the settings for radio connections between the scoreboard and control console:

1. Cycle power to the scoreboard.

2. After approximately seven seconds, the radio settings will be displayed. The first

values are the broadcast settings (“b1”), and the second are the channel settings (“C1”). These values must match the settings within the console.

Note: If these settings do not appear, the radio receiver(s) may need to be repaired/replaced.

To make sure the current radio settings match the receiver in the scoreboard, refer to the operation manual of the particular control console being used (see Section 1.4).

Scoreboard Troubleshooting 27

Figure 20: Radio Receiver w/ Cover Figure 21: Radio Receiver w/o Cover

Radio Interference

If it has been determined that a nearby scoreboard‟s radio signal is interfering, the broadcast and channel settings of the radio receiver inside the scoreboard(s) must be changed. For more information, refer to the Gen V Radio Installation Manual ED-13831, available online at www.daktronics.com/manuals.

1. To locate the radio receiver, look for the small black antenna sticking out the front of

the scoreboard.

2. Open the access panel to which the receiver is

attached as described in Section 5.2.

3. The radio receiver has a plastic cover. Three status

indicator LEDs are visible (Figure 20).

Note: While it is necessary to have the scoreboard powered on to check the LED indicators, always disconnect scoreboard power before servicing.

4. Remove the four screws using a #2 Philips

screwdriver and lift off the cover.

5. Inside the receiver are a channel switch (S1) and

two broadcast jacks (J4, J5) with a jumper.

Figure 21 shows the different configurations for the small jumper wire that sets the radio broadcast (BCAST) mode. Move the jumper wire to the desired broadcast location.

6. Use a small flathead screwdriver to set the S1 switch to the desired channel (1-8).

7. Screw the cover back on and securely close the access panel.

8. Enter the correct sport code and new radio settings into the console to test the radio

control (refer to the appropriate scoreboard controller manual).

IMPORTANT NOTES:

1. Always disconnect scoreboard power before doing any repair/maintenance work on the message centers.

2. Permit only qualified service personnel to access internal display electronics.

3. Disconnect power when not using the scoreboard.

6.1 Team Name Message Center System Overview

Team name message centers (TNMCs) use amber, red, or white LEDs to display team names (home and guest) in place of vinyl captions (Figure 22). On the CR-2004, TNMCs are also used to display the current BATSMEN names as well as a HOW OUT description. TNMCs for the CR-2004 are available with two different pixel dimensions: 8x32 and 8x64. Characters are shown on one line using single- or double-stroke fonts up to 10" (254 mm) high for 34 mm TNMC units.

* TNMCs are typically installed in pairs; double this value to find the total added weight.

6.2 Initialization Information at Startup

Every time the display is powered up and there is no All Sport® signal present, the display will run through an initialization process, during which it will test all LEDs and addresses. First, the message center will display the proper address number.

If the entire display fails at startup, power may not be properly connected, or the address setting may not be correct on the display driver. Check both in the event of a failure.

Note: For displays built before September 2009, refer instead to Drawings A-252645, A-252681, A-294858, or A-294919.

Display signal routing can be summarized as follows:

1. Data from the All Sport

2. The signal travels to the driver/power enclosure through the J1 connector on the

signal surge arrestor card.

3. Data exits at J42 via current loop harness, and connects with P43 at the driver

assembly. A power/signal interconnect (ribbon cable) carries the signal to the first module, and the signal relays from module to module, in daisy-chain style, until it reaches the last module on the message center.

Display power routing can be summarized as follows:

1. Incoming power terminates at the terminal block in the scoreboard driver enclosure.

Using the same harness and J42-P43 connections as signal, power is then routed to the display driver where it then travels to the power supply assembly.

2. From the power supply assembly, power is relayed to the first module, and then

from module to module.

3. The modules and display driver draw their power directly from the power supply

assemblies (3-12.5 VDC). The power supply voltage is set by a resistor loaded on the module (via J4).

Note: In displays built before September 2009, modules draw their power directly from the power supply assemblies (6.5 V for red LED modules, 9 V for amber), while the display driver receives 16 V power from a transformer on the driver tray.

(Figure 29). Turn each fastener a quarter-turn clockwise (if using a nut driver, turn the top latch counter-clockwise and the bottom latch clockwise).

Note: Do not over turn the fastener!

3. While holding onto the module, push it out and turn it in such a manner (generally a

sideways, diagonal turn) that it can be pulled back through the frame opening.

4. Carefully disconnect all power and signal cables. It may be helpful to label the cables

to know which cable goes to which connector when reattaching a module.

5. Reconnect all power and signal cables to the new module and push it back through

and out the front of the display frame.

6. Re-latch the fasteners.

7. Power up and test the scoreboard/display to see if changing the module has resolved

the problem.

40 TNMC Troubleshooting & Maintenance

Weather-stripping

To ensure that the display is waterproof, weather-stripping has been installed around each module. It is important that the weather-stripping is attached properly at all times, or water may leak into the display and damage the components.

When installing a new module, take note of the following points:

 The weather-stripping on the back edge of the module must be intact and in good

condition to prevent water from seeping into the display.

 The module latches must be fully engaged to create a watertight seal around the edge

of the module. The module should be firmly seated against the display when the latches are fully engaged.

6.8 Power Supplies

Power supply configurations will vary depending on the number and/or color of modules.

Replacing a Power Supply

To remove a power supply from the display:

1. Access the internal components using the appropriate Front/Rear Access method

described in Section 6.5.

2. Disconnect all the wires connected to the power supply.

3. Loosen the screw securing the power supply and slide it out of the display cabinet.

Note: In displays built before September 2009, use a 9/32" nut driver to remove the

hardware securing the power supply.

4. Fasten the new power supply in place and reconnect all wires.

6.9 Display Maintenance

Complete a yearly inspection to maintain safe and dependable display operation. This inspection should address the following issues:

 Loose Hardware: Verify that fasteners, such as bolts and rivets, have not come loose.

Check and tighten or replace fasteners as required.

 Excessive Dust Buildup: It may be necessary to occasionally vacuum the inside of

the display cabinet to remove dust/dirt buildup that may interfere with airflow.

 Water Intrusion – Water stain marks: Water can enter the display where weather-

stripping has come loose or deteriorated; where fasteners have come loose, allowing gaps in the panels; or where moisture may be entering around hardware. Check electronic components for corrosion.

 Corrosion: Check the paint, and look for possible corrosion, especially at footings,

structural tie points, and ground rods and other types of grounding electrodes.

Note: If any of the preceding conditions are discovered, make the necessary repairs or take corrective action immediately.

Section 7: Additional Scoreboard Options

7.1 Radio Control

Radio control is an option for all Daktronics outdoor LED scoreboards. The system provides scoreboard control via a 2.4 GHz, extra-high frequency FM signal.

The radio transmitter and receiver are not standard. This setup requires a control console equipped with radio output as well as a radio receiver plugged into the power terminal block in the driver/power enclosure and mounted internally to the front panel of the scoreboard.

For additional information about this option, contact a Daktronics representative; for complete information on setting up radio communication control, refer to the Gen V Radio Installation Manual (ED-13831), available online at www.daktronics.com/manuals.

In no event shall Daktronics be liable to Purchaser or any other party for loss, damage, or injury of any kind or nature arising out of or in connection with this Warranty in excess of the purchase price of the Equipment actually delivered to and paid for by the Purchaser. The Purchaser’s remedy in any dispute under this Warranty shall be ultimately limited to the Purchase Price of the Equipment to the extent the Purchase Price has been paid.

The Warranty contained herein extends only to the original end-user (which may be the Purchaser) of the Equipment and no attempt to extend the Warranty to any subsequent user-transferee of the Equipment shall be valid or enforceable without the express written consent of Daktronics.

Any dispute between the parties will be resolved exclusively and finally by arbitration administered by the American Arbitration Association (“AAA”) and conducted under its rules, except as otherwise provided below. The arbitration will be conducted before a single arbitrator. The arbitration shall be held in Brookings, South Dakota. Any decision rendered in such arbitration proceedings will be final and binding on each of the parties, and judgment may be entered thereon in any court of competent jurisdiction. This arbitration agreement is made pursuant to a transaction involving interstate commerce, and shall be governed by the Federal Arbitration Act.

The rights and obligations of the parties under this warranty shall not be governed by the provisions of the United Nations Convention on Contracts for the International Sales of Goods of 1980. Both parties consent to the application of the laws of the State of South Dakota to govern, interpret, and enforce all of Purchaser and Daktronics rights, duties, and obligations arising from, or relating in any manner to, the subject matter of this Warranty, without regard to conflict of law principles.
