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

The installation specification drawings listed in Appendix A show the recommended number of beams and spacing between them. The drawings also indicate the size of beams required to support the scoreboard at different heights and at various wind speeds. Use the following table to determine which drawings provide the installation specifications for each model:

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 scoreboard 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 or 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.

Mechanical Installation 11

Figure 4: Lifting Methods

Figure 5: Eyebolt Plane Load

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.

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.

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

4.5 for more information on the power/signal connections between sections.

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.

Figure 8: Mounting with Vertical Spacers

Scoreboard Mounting Using Vertical Spacers

Many customers add message centers or advertising panels to the top or bottom of their scoreboards, and in some cases the depth of the add-on component may not match the depth of the scoreboard. This will typically be scoreboards that are 8" deep.

To create a uniform appearance for the overall display, Daktronics recommends using vertical spacers behind the scoreboard so that the front face of the display lines up evenly with the front face of the added component. The concept is illustrated in Figure 8 and Drawing A-182909 in Appendix A.

During the installation, spacers are placed between the mounting beams and the back of the scoreboard cabinet. Spacer size is determined by the height and the extra depth required for the front surface of the scoreboard to match that of the optional message center or ad panel.

Note: Daktronics does not provide these spacers.

3.4 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.

Figure 9: Ad Panel Mounting with C-channel, Side View

3.5 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. Refer to Figure 9 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 9.

4. Place 1/2" 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.

Section 4: Electrical Installation

CAUTION: Only qualified individuals should terminate power and signal cable and 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

The diagram shown in Figure 10 illustrates a typical wired setup between a multi-section outdoor scoreboard and controller. Daktronics part numbers are shown in parentheses.

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.

Multi-section outdoor scoreboards require a dedicated 120 V or 240 V circuit for incoming power (refer to the Specifications in Section 2). The display itself has no breakers or fuses.

WARNING: It is critical that the scoreboard circuit be fused at 15 A and that all conductors used must be designed to pass a 15 A current in normal operation. 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.

18 Electrical Installation

Figure 12: Power Warning Label

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.

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

Both power and signal cables are routed into the scoreboard from the rear through two plastic plugs for conduit connection. All power and signal wiring terminates at the master driver enclosure. Note that systems with radio control do not require external signal wiring.

Look for a warning label similar to Figure 12 to locate the front access panel to the driver enclosure. Remove the screws or loosen the latches to open the access door panel. Remove the metal cover of the driver enclosure to expose the driver components (Figure 13).

Refer to the component location drawings in Appendix A for precise power/signal termination location for each model.

Electrical Installation 19

Figure 13: Driver Enclosure & Power Terminal Block

Figure 14: Digit Segment POST

Connect the appropriate wires coming through the rear of the scoreboard to the power terminal block, as shown in Figure 13.

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 120 V outlet close to the disconnect box specifically for this purpose.

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 14 shows an example of the LED bar test pattern that each digit performs.

Radio Settings

If a radio receiver is installed, the radio Broadcast and Channel settings will be displayed in the Home and Guest or clock digits 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 5.9 for more information on radio installations.

Figure 16: Driver Fiber

Connection Location

4.4 Signal Connection

For wired setups, route signal cable through the conduit knockout on the rear of the scoreboard to the signal surge arrestor card (Figure 15), located just above the power termination block in the driver enclosure.

At the SIGNAL IN terminal block, connect the red signal wire to the positive terminal and the black wire to the negative terminal.

Note: Be sure to properly connect the shield (silver) wire to the SHIELD terminal.

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

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 (part number W-1242). See Figure 16 for the location of the fiber connector on a 16column driver. This method requires a signal converter between the All Sport console‟s scoreboard output and the fiber optic cable (not provided by Daktronics).

Multiple Driver Connections

Some models in the multi-section outdoor scoreboard line require multiple drivers in each scoreboard section, and use a master/slave driver system. Master and slave drivers function identically, but slave units lack the power termination block and signal surge suppression card. When one section has multiple drivers, they simply plug into one another, and this is done at the factory. Drivers between sections, however, require additional on-site connection as described in Section 4.5.

Note: Scoreboards capable of displaying speed of pitch (SOP) have an additional master driver. These models also require a separate signal connection (either wired or radio) from a dedicated speed of pitch All Sport 5000 console. Refer to the Baseball Speed of Pitch Systems Configuration Manual (ED-12224), available online at

www.daktronics.com/manuals, for more information about setting up an SOP system.

4.5 Power/Signal Connections Between Sections

Most multi-section outdoor scoreboards use a single power/signal interconnect cable between a driver in the upper section and a driver in the lower section (Figure 17).

It is common for the top driver to be located behind the right-most HOME score digit with the bottom driver located behind the right-most digit of the left-most set of digits. Refer to the component location drawings in Appendix A for exact driver locations.

Electrical Installation 21

Figure 17: Typical Upper/Lower Scoreboard Section Connection (Digits Removed to Show Drivers)

1. On the upper 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 bottom of the upper cabinet

through the hole in the top of the lower cabinet, and plug it into the driver.

 If the lower section contains the master driver, the harness will connect to J42.  If the lower section contains the slave driver, the harness will connect to P43.

3. With four-section scoreboards, be sure to also connect any plugs extending from the

right side of the left cabinets to the corresponding jacks on the left side of the right cabinets.

Note: Similar connections exist between the upper and lower cabinets of multisection, single-driver scoreboards as well.

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.
