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 top sponsor panels to the posts.

Post Installation The scoreboard mounts on four 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 the MP-378 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 MP-378 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 sixteen points. Figure 3 shows the location of the mounting points on the rear of the scoreboard.

Sixteen sets of mounting hardware are provided to attach the scoreboard to the posts. Additional hardware sets are provided to attach the optional sponsor panels, if ordered. A mounting hardware set 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 using the hardware. A ¼” flat bar with tapped holes is riveted to the inside of the scoreboard’s aluminum extrusion frame. 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 lower section of the scoreboard against the posts on the ground. Make sure the mounting points are aligned with the posts. 2.If the eyebolts are installed in the upper section of the scoreboard, unscrew them and screw them into the lower section of the scoreboard. 3.Screw the threaded rods into the tapped holes in the scoreboard. 4.Place an aluminum angle bracket over the threaded rods at a mounting point. 5.Place a washer over each threaded rod. 6.Screw the nuts onto the threaded rods so that the bracket is loosely held in place. 7.Repeat steps 4 -6 at the other mounting points. 8.Raise the section into place and tighten the nuts to clamp it in place on the posts. 9.Unscrew the eyebolts from the lower section of the scoreboard and screw them into the upper section of the scoreboard. 10.Place the upper section of the scoreboard against the posts a few inches above the lower scoreboard section. Make sure the mounting points are aligned with the posts. 11.There is a cable with a 15 pin plug which is accessible through an opening in the top of the lower section frame. Plug this cable into the 15 pin socket which is accessible through an opening in the bottom of the top section frame. 12.Place the upper section of the scoreboard on top of the lower section. 13.Attach the mounting hardware by the same method as the lower section. 14.Tighten the nuts to clamp it in place on the posts.

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 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 the nuts onto the threaded rods so that the bracket is loosely held in place. 6.Repeat steps 4 -6 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 horn, installing the ScoreLink 300 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 connect the scoreboard to the power source: 1.Drive one or more 5/8” x 8’ copper clad ground rods in the soil near the scoreboard. 2.Connect #6 bare copper wire to the ground rods using 5/8” brass tear drop connectors. 3.Attach the ground conductor to the each section of the scoreboard with copper mechanical lugs. Fasten the mechanical lugs to the scoreboard using self tapping sheet metal screws.

Power Connections The scoreboard may be connected to 240 VAC single phase or 120 VAC service at the scoreboard. Maximum power consumption of Model MP-378: 5100 Watts. Make sure that 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.Remove the rear access panel of the upper scoreboard section and the dome plugs on the plate below the access panel. Figure 5 shows the location of the upper rear access panel and the dome plugs.

2.Figure 6 shows the view behind the access panel. Feed the power cables through one of the holes in the plate below the access panel. 3.Crimp fork terminals to the power cable wires.

4.If you are going to connect the scoreboard to a 240 VAC supply, connect one AC line wire to position 2, AC neutral wire to position 3, and the other AC line wire to position 4 of terminal strip T4 on the junction chassis according to figure 7.

5.If you are going to connect the scoreboard to a 120 VAC supply, connect the AC line wire to position 2 and the AC neutral wire to position 3 of terminal strip T4 on the junction chassis. Add a jumper from position 2 to position 4. This jumper is not provided. Refer to figure 8.

Install a power disconnect that isolates all current carrying conductors on one of the posts below the scoreboard (not the ground conductor). 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.

Horn Installation The items provided to install the horn are the horn, the weatherproof back box, the mounting bolts, and the mounting bracket. Items which are not provided but are necessary for proper installation are ¾” flexible conduit, a ¾” right angle male conduit connector, a ¾” straight male conduit connector, two wires, and four forked crimp terminals. The electrical requirements for the horn are 0.35 A 120 VAC. The horn assembly is attached to the left side of the scoreboard for models with top sponsor panels. These models have two tapped holes at the mounting point. Other models may have tapped holes on the left side of the scoreboard or have one tapped hole on the top of the scoreboard at the mounting point. Mounting bolts are screwed into the tapped holes at the factory. The following steps describe the assembly and mounting of the horn: 1.Remove the mounting bolts from the scoreboard. 2.Cut a piece of ¾” conduit of sufficient length to reach from the horn mounting point to one of the knockouts below the upper access panel. 3.Attach the ¾” right angle male conduit connector to one end of the conduit and the ¾” straight male conduit connector to the other end. 4.Cut two pieces of wire of approximately 7 feet longer than the conduit. 5.Push the wires through the conduit.

6.The horn mounting bracket has a side mount bracket attached. If the horn is going to be mounted on top of the scoreboard, remove the side mount bracket as seen in figure 9.

7.Push the end of the conduit with the right angle male conduit connector through the 2” diameter hole in mounting bracket. 8.The weatherproof back box has two threaded conduit holes. Screw the provided conduit plug into the hole near the word “TOP” inside the weatherproof back box. 9.Feed the wires through the other back box conduit hole and screw the right angle conduit connector to the back box. 10.Attach the weatherproof back box to the mounting bracket using the provided 8-32 x 1/2” Phillips head machine screws, #8 split-lock washers, and 8-32 hex nuts as shown in figure 10.

11.Remove the horn signal mounting plate from the horn base by loosening the Phillips head screw on the base as seen in figure 11.

12.The word “TOP” is stamped on the front side of the horn signal mounting plate. Pass the two wires that are inside the back box through the horn signal mounting plate center hole from the rear.

13.Align the horn signal mounting plate with the back box so that the word “TOP” on the horn signal mounting plate and the back box should be oriented in the same direction and the screw hole on the bottom edge of the horn signal mounting plate should be directly over the gap in the back box gasket as seen in figure 12. 14.Fasten the horn signal mounting plate with the four 8-32 x 7/16” machine screws that are provided with the back box.

15.Crimp forked terminals on the ends of the two wires and attach them to the plug receptacle seen in figure 13.

16.Slide the slot on the side of the horn base over the tab on the horn signal mounting plate and tighten the Phillips head screw on the other side of the horn base. 17.Fasten the horn assembly to the scoreboard using the mounting bolts from the scoreboard as seen in figure 14.

18.Crimp forked terminals on the ends of the two wires that protrude out of the other end of the conduit. 19.Pass the wires through one of the knockouts below the upper access panel. 20.Fasten the conduit connector to the knockout panel and connect the wires to T-2.

ScoreLink 300 The ScoreLink 300 RF MODEM SYSTEM is designed to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard MM and MP series scoreboards. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the ScoreLink 300 RF MODEM SYSTEM OWNER’S HANDBOOK for installation instructions.

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 ¼” 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 ¼” stereo jack. Figure 15 shows the control cable wire connection points on the rear of the ¼” 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 holes in the plate below the upper access panel. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to T1 terminal block on the junction chassis according to figure 16.

4.Reinstall the access panel.

Control Console Connections The 10 ft. extension cable has two molded ¼” 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 ¼” stereo jack on the junction box or the ScoreLink 300 Transmitter, if purchased. 2.Plug the other end into the ¼” 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

TROUBLESHOOTING TIPS

Before calling Electro-Mech Scoreboard Co. for customer support of a scoreboard problem, it is helpful to make note of all the symptoms. If the scoreboard does not turn on lamps, please check the following items: 1.Make sure the control console power cord and the extension cable are plugged. 2.Verify that the control console LCD display shows game information. 3.Press control console keys and look for changes on the game information shown on the LCD display. 4.Check the circuit breaker that supplies power to the scoreboard. 5.Remove the upper access panel cover and check the voltages present at main power terminal block. 6.Check the fuses. 7.Take the control console and the extension cable to the scoreboard. Temporarily disconnect the control cable from the main control terminal block and plug the extension cable into the test jack. Plug the control console power cord into a 120 VAC receptacle. If the lamps are now illuminated and the scoreboard reacts to control console entries, there may be a problem with the control cable or the ScoreLink 300 modem, if purchased.

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

LAMP REPLACEMENT

Remove the protective mask covering each lamp bank to access the lamps. To avoid damage to the plug in module,always turn off the power to the scoreboard when changing lamps. We recommend using a felt pen or tape to mark lamps that will not light. The scoreboard uses 15 watt 120 VAC frosted medium based appliance lamps (also known as 15A15IF lamps).Never replace these with higher wattage lamps.
