SCOREBOARD INSTALLATION

This part of the manual describes the mechanical and electrical installation of the scoreboard.

One of the items listed below must be purchased in order to complete the installation:

• Control cable (length dependent upon installation site layout)
• ScoreLink RF Modem System

Items not provided by Electro-Mech Scoreboard Company that are necessary for

installation:

• Two posts (Additional posts may be needed if an alternate configuration is specified.)
• Power cable to connect the scoreboard to the power source
• Grounding hardware
• A grounded NEMA 5-15R 120 VAC receptacle for the control console at the scorekeeper’s table.

Items not provided that are recommended by Electro-Mech Scoreboard Company for

• A weatherproof power disconnect at the scoreboard

Electro-Mech Scoreboard Company performs installations in some areas. In other areas, we can help you contact an independent installer. 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 ID 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 Model 1131 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 Model 1131 scoreboard with an optional side ID panel.

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 ID 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 or bottom ID panel(s), if purchased.

Mounting The Optional Top Or Bottom ID Panel Additional hardware sets are provided to attach any optional top or bottom ID panels, if purchased. The following steps describe how to mount an ID panel on the posts: 1.Raise the ID panel in place above or below the scoreboard. Make sure the mounting points are aligned with the posts. 2.Screw the threaded rods into the tapped holes in the ID 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 the ID panel 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.

Power Connections The scoreboard requires 120 VAC, 60 Hz service at the scoreboard to operate properly. Maximum power consumption of Model 1131: 200 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 through 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.

GAME TIME OPERATION

This scoreboard is operated with a 37-key control console. Figure 9 shows the keypad layout on the control console.

Immediately after the control console power cord is plugged into a 120 VAC source, the console LCD display will read:

ELECTRO-MECH 314
BASEBALL_1  0CD0
00 D15:00  -  00
  00 0-0-0  00

After a few seconds the display will read:

The scoreboard will display:

Guest Score: 0 Home Score: 0 Guest Pitches: 0 Home Pitches: 0 Inning: 0 Time: 0:15

The control console LCD display shows the total runs for the Guest and Home teams along with a 4-digit Game Clock (or a 3-digit Game Clock for times greater than one hour), Inning, Guest and Home Pitches, and Ball-Strike-Out counts. It also provides instructions to help the operator use some of the console functions. Figure 10 explains the LCD display layout.

SERVICING THE SCOREBOARD

While your scoreboard was designed for years of trouble-free operation, some problems may occasionally occur. Electro-Mech Scoreboard Company offers onsite service in some areas. In other areas, we can help you contact an independent service technician. In areas in which service is not available from Electro-Mech Scoreboard Company, we will make every effort to answer your questions. Our trained personnel at Electro-Mech Scoreboard Company are ready to answer your questions from Monday to Friday during the hours of 8 AM to 5 PM Eastern Standard Time. Be sure to know your scoreboard model number when calling. Scoreboard replacement parts are always available. Damaged parts can usually be repaired at a significant cost savings. Our convenient toll free number is listed at the bottom of every page in this manual.

If the scoreboard turns on LEDs, but does not operate normally, make note of which functions are affected. If some LEDs either never turn on or always stay on, make note of their specific locations on the scoreboard. Refer to the COMPONENT REPLACEMENT section of this manual before changing parts.

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 your hand 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 power and driver logic components are located behind the right (as you are facing the scoreboard) score digits -- usually HOME. Figure 13 shows the components with the digit mask removed.
