In areas in which installation service is not available from Electro-Mech Scoreboard Company, we will make every effort to answer your installation questions. Qualified personnel should perform the scoreboard installation. Consult national and local codes before installation.

MECHANICAL INSTALLATION

The mechanical installation includes installing the posts and mounting the scoreboard and the optional sponsor panels (if purchased) to the posts.

Post Installation The scoreboard, in its standard configuration, mounts on two posts. Typically installers will use steel pipes or I-beams. In order to reduce the glare from the sun on the front of the scoreboard, position the posts so that the front of the scoreboard is angled away from the afternoon sun, if possible. The mounting hardware will accommodate posts up to 7 inches outer diameter. Sink the posts in reinforced concrete footings. Figure 1 shows the spacing of the posts for a 1520 scoreboard. The specifications for the posts and concrete footings are dependent upon the expected local wind and soil conditions, the height of the scoreboard from the ground, and the local building codes. Electro-Mech Scoreboard Company assumes no responsibility for the installation of scoreboards by others.

Figure 2 shows the spacing of the posts for a 1520 scoreboard with an optional top sponsor panel. This panel is a separate unit that mounts on the same posts as the scoreboard.

Mounting The Scoreboard The scoreboard is attached to the posts at four points. Figure 3 shows the location of the mounting points on the rear of the scoreboard.

MOUNTING HARDWARE

Four sets of mounting hardware are provided to attach the scoreboard at these points. Additional hardware sets are provided to attach the optional sponsor panels, if ordered. A single set of mounting hardware consists of a steel angle bracket, two threaded rods, two washers, and two nuts. Figure 4 shows an overhead cross section view and a side cross section view of the scoreboard attached to a post at a mounting point. A steel bar is riveted inside the scoreboard’s aluminum extrusion frame. The bar has two tapped holes. The threaded rods screw into these tapped holes. The washers and nuts are used to clamp the steel angle bracket against the steel post and hold the scoreboard in place.

The following steps describe how to mount the scoreboard on the posts: 1.Place the scoreboard cabinet against the posts on the ground. Make sure the mounting points are aligned with the posts. 2.Screw the threaded rods into the tapped holes in the scoreboard. 3.Place a steel angle bracket over the threaded rods at a mounting point. 4.Place a washer over each threaded rod. 5.Screw the nuts onto the threaded rods so that the bracket is loosely held in place. 6.Repeat steps 2 - 5 at the other mounting points. 7.Raise the scoreboard into place and tighten the nuts to clamp the scoreboard in place on the posts.

Note: Be sure to leave enough space on the posts above the scoreboard for the optional top sponsor panel, if purchased.

Mounting The Optional Top Sponsor Panel Additional hardware sets are provided to attach the optional top sponsor panels, if purchased. The following steps describe how to mount the top sponsor panel on the posts: 1.Raise the top sponsor panel in place above the scoreboard. Make sure the mounting points are aligned with the posts. 2.Screw the threaded rods into the tapped holes in the top sponsor panel. 3.Place a steel angle bracket over the threaded rods at a mounting point. 4.Place a washer over each threaded rod. 5.Screw a nut onto each threaded rod so that the bracket is loosely held in place. 6.Repeat steps 2 - 5 at the other mounting points. 7.Tighten the nuts to clamp it in place on the posts.

ELECTRICAL INSTALLATION

We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the scoreboard. These connections include grounding the scoreboard, connecting the scoreboard to a power source, installing the ScoreLink RF Receiver or the control cable, and connecting the control console.

Ground Connection The National Electrical Code requires a scoreboard (electric sign) to be grounded. Grounding the scoreboard helps the scoreboard electronics operate properly and helps minimize damage if it is struck by lightning. Metal posts do not provide an adequate ground path. The following steps describe how to ground the scoreboard:

1.Drive one or more 5/8-inch x 8-foot copper clad ground rods in the soil near the scoreboard. 2.Connect #6 bare copper wire to the ground rods using 5/8-inch brass tear drop connectors. 3.Remove the rear access panel and the dome plugs on the plate near the access panel. Figure 5 shows the location of the access panel and the dome plugs. 4.Pass the ground conductor through the one of the knockouts in the plate near the access panel and connect it to the ground lug (Ground) on the chassis.

Version 1 of Model 1520:

Power Connections The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model 1520: 360 Watts. Make sure the power cable is rated for this electrical load. Install the power cable in conduit. Avoid running the power cable in close proximity to the control cable. The following steps describe how to connect the scoreboard to the power source: 1.Feed the power cable through one of the knockouts in the plate near the access panel. 2.Crimp fork terminals to the power cable wires. 3.Connect the AC line wire and AC neutral wire to the Main Power terminal block on the chassis according to figure 6.

Install a power disconnect that isolates all current carrying conductors (not the ground conductor) on one of the posts below the scoreboard. If a secondary switch is installed near the scorekeeper’s table, it should also isolate these conductors. Place the power disconnect in the OFF position between games to help protect the scoreboard from lightning damage. A power disconnect on the scoreboard post also provides a convenient way of turning the scoreboard off during maintenance or repairs.

ScoreLink RF Modem System The SCORELINK RF MODEM SYSTEM is designed to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard LED scoreboards. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the installation manual provided for this product.

Control Cable Installation The control cable connects the scoreboard to the control console. Install the control cable in conduit. If the cable is ever damaged, it is easier and less expensive to replace a cable in conduit. A small junction box with a 1/4-inch stereo jack mounted on the face plate is attached to the control cable at the point of operation of the scoreboard. This junction box should be securely mounted in a clean, dry area within ten feet of the rear of the control console. Most customers order the control cable with the junction box attached. Some customers prefer to attach the junction box after the cable is installed. Those customers must solder the control cable to the 1/4-inch stereo jack. Figure 7 shows the control cable wire connection points on the rear of the 1/4-inch stereo jack.

The following steps describe how to connect the control cable to the scoreboard: 1.At the rear of the scoreboard feed the control cable one of the knockouts. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to the Control Cable terminal block on the chassis according to figure 8.

4.Reinstall the access panel.

Control Console Connections The 10 ft. extension cable has two molded 1/4-inch stereo plugs attached to it. It is used to connect the control console to the junction box. The following steps describe how to connect the control console: 1.Plug one end of the extension cable into 1/4-inch stereo jack on the junction box. 2.Plug the other end into the 1/4-inch stereo jack mounted on the control console back plate. 3.Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle.

Control Console Safety Warning This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding- type plug.

SCOREBOARD STARTUP

1.Place the power disconnect for the scoreboard in the ON position. 2.Plug one end of the extension cable into 1/4-inch stereo jack on the junction box. 3.Plug the other end into the 1/4-inch stereo jack mounted on the control console back plate. 4.Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle.

COMPONENT REPLACEMENT

LED digits and indicators are serviced from the front of the scoreboard.

LED Digits And Indicators Replacement

The LEDs that form digits and indicators are soldered on circuit boards mounted behind metal masks. Do not attempt to replace individual LEDs. In case of a malfunction, the entire LED circuit board must be removed. To avoid damage to the LED driver PCB, always turn off the power to the scoreboard when removing or replacing LED digits and indicators. Figure 11 shows the components of a LED digit assembly. LED indicator assemblies are similar in construction.

The following steps describe how to replace a defective LED digit:

1.Remove the sheet metal screws that fasten the mask to the face of the scoreboard. Caution: Support the mask with before removing the last screw. The ribbon cable that connects to the rear of the circuit board is not designed to support the weight of the assembly. 2.Disconnect the ribbon cable from the rear of the circuit board. For assemblies with two LED digits, it will be necessary to disconnect the ribbon cables from both circuit boards. The cables are labeled to indicate the proper circuit board connection. Caution: Do not let the cable hang outside of the scoreboard. It is easily cut by sharp metal edges. Damage to the ribbon cable may create short circuit paths that will damage the LED driver PCB. 3.Place the assembly on a flat surface and remove the 6-32 kep lock nuts that hold the defective circuit board in place. 4.Remove the circuit board from the assembly. 5.Align the mounting holes in the replacement LED digit circuit board with the threaded studs on the mask and install it on the mask using the 6-32 kep lock nuts. 6.Plug the ribbon cable onto the header on the back of the circuit board. Refer to figure 12 in order to plug the ribbon cable IDC connector onto the circuit board in the proper orientation.

7.Reinstall the assembly using the sheet metal screws.

All other components are located behind the various digits on the right side of the scoreboard (as you are facing the scoreboard). Figure 13 shows the components with these digits removed.
