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 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 the MP-328 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.

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 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-328: 3600 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 and the dome plugs on the plate below the access panel. Figure 6 shows the location of the rear access panel and the dome plugs.

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 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.

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 as well as all LED 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 16 shows the control cable wire connection points on the rear of the ¼” stereo jack.

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 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.

COMPONENT REPLACEMENT

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.

All other components are located behind the rear access panel. Figure 20 shows the components behind the access panel.
