BEST PRACTICES FOR PERSONAL SAFETY AND PRODUCT CARE

Thank you for choosing Electro-Mech products for your athletic facility. We hope you will be pleased with the performance and appearance of your scoreboard. The information in this document will help you maintain the equipment in its best condition.

Receiving Your Scoreboard

Depending on the shipping method, cardboard sheets, a partially open wooden crate, or a complete enclosure may protect the scoreboard cabinet. It is important to inspect the scoreboard packaging for damage when it arrives ─ before signing any paperwork telling the trucking company that you have received everything in good condition. If damage has occurred to the packaging, then damage may have occurred to the scoreboard. Where you find dents, scrapes, or holes in the packaging, peel back the cardboard or other packing materials to expose the scoreboard cabinet. Make notes on the paperwork provided by the trucking company before accepting delivery. If the damage appears to be severe, refuse the shipment. Contact Electro-Mech as soon as possible if you suspect shipping damage.

We recommend keeping the scoreboard display in its packing materials until the day of installation. It is important to keep the packing materials dry while they are on the scoreboard. Wet cardboard can adhere to the scoreboard face and damage the finish.

If your scoreboard cabinet arrives in a wooden crate, take care to avoid scraping the cabinet with tools, nails, or lumber when prying apart the nailed sections. Make certain to pry the wooden pieces apart from each other rather than trying to apply force against the scoreboard cabinet. Aluminum is strong, but a steel crowbar is stronger.

Once the crate is out of the way, remove the cardboard padding. You may need to remove a few labels adhered to the side of the cabinet for shipping. At this point, your scoreboard cabinet is unpacked and ready for installation.

Storage Prior to Installation

Unless you are planning to install your scoreboard on the same day it arrives, you will need to prepare a clean, dry, secure area for storage. Even though your scoreboard display is designed for outdoor use, you will need to keep it away from rain, dirt, accidental damage, and abuse. As an example of why this is important, outdoor scoreboard cabinets include drain holes along the bottom. These drain holes will likely become clogged with dirt if the sign is stored on the ground, especially in the rain.

Stand the scoreboard cabinet upright prior to assembly; never lay it facing up or down. Never stack things on top of the scoreboard cabinet while it is in storage.

These recommendations apply equally to ID panels and other items that may have shipped with your scoreboard.

Conditions of Installation and Use for Outdoor Scoreboards

This scoreboard display is designed for installation and use in a wet environment. That is, rain and other common weather conditions will not hinder the operation of this product when it is installed correctly. The scoreboard cabinet is not watertight. Instead, it is designed to withstand normal outdoor conditions by routing water through the cabinet and out of drain holes in the bottom. Do not block the drain holes. If the scoreboard display is to be installed immediately above something ─ for instance, an ID panel or the ledge of a wall ─ please allow 1/4-inch or more clearance below the cabinet. Alternatively, you could provide matching drain holes in the top of the object below the scoreboard.

Although this scoreboard display was designed for portable use, it may be installed permanently. Outdoor scoreboard displays are typically installed on steel posts. It is important to properly install these posts and allow concrete footings time to cure before using them to support the scoreboard cabinet.

The scoreboard display includes an AC power cord fitted for a standard 120 VAC electrical outlet. When the display is not in use, you should disconnect it from power. For portable models, this typically means unplugging the power cord. In situations where access to the power cord will be difficult, we recommend installing a disconnect switch near the scoreboard display. In the "off" position, the switch should isolate all load-carrying conductors (not the ground). Disconnecting power will help protect the scoreboard electronics from nearby lightning strikes and other power fluctuations that might otherwise travel along the power cables.

MECHANICAL INSTALLATION

This section of the manual describes installing the scoreboard display, in its standard configuration. This scoreboard was designed for portable use. You may provide a permanent structure if you like. But, in most cases, these displays will be mounted on a portable stand. Electro-Mech offers a "T-Cart" portable leg kit for this purpose. Instructions for attaching the portable leg kit are provided in the documentation that ships with that product.

If you wish to attach your scoreboard display to a different support structure, you may take advantage of the mounting plates included on each side of the cabinet. These plates have tapped holes, spaced nine inches center-to-center, along the sides of each cabinet. The tapped holes accept 1/2-inch-13 threaded bolts. Although the options for support structures are almost limitless, a pair of 3-inch wide square tubes, one bolted to each side of the cabinet, makes a good example post supports for a permanent installation. For Model LX7620, support brackets or posts will need to be positioned 60 inches apart (inside spacing) to provide room for the cabinet.

ELECTRICAL INSTALLATION

The standard configuration of this scoreboard system includes a detachable power cord with GFCI protection feature. We recommend testing the GFCI feature during the initial installation and subsequently at intervals of three months or less. The GFCI test procedure is imprinted on the body of the AC plug housing.

Power and data cables enter the cabinet via an opening in the back. Sockets for power and data are protected by a cover plate. The cover plate is held to the back of the scoreboard cabinet by two thumb screws. You will find an extra captive nut in the back of the cabinet, which is there so that you can rotate the cover plate up and hold it out of your way temporarily while you plug in the cables.

If your facility requires another method for attaching power or data cables ─ for instance, if you need to mount this display on a wall ─ we can provide other options for routing and terminating the electrical connections. Let your scoreboard sales rep know about any special requirements BEFORE we begin building your cabinet. If your scoreboard package includes special accessories such as a Stadium Sound System or Video Display, there may be additional cabling and conduit needed to support this equipment. Please consult the documentation provided with these items.

Power Considerations

A portable scoreboard display requires a standard (NEMA 5-15R) AC power receptacle providing 120 VAC at 60 Hz. On the other side of the AC receptacle, the power may come from an inverter attached to a battery charged by solar energy, a gasoline powered generator, or the local power company. It is beyond the scope of this document to consider all the possible variations. Here we will assume that the receptacle is available. Likewise, we will assume another receptacle is available for the control console.

The Model LX7620 practice segment timer display draws a maximum of 0.7 amps. Use only the detachable power cord with the GFCI safety feature to connect the display to a power receptacle. If this cord is lost becomes damaged, contact Electro-Mech to purchase a replacement. We do not recommend operating this display ─ especially outdoors ─ without a cord that includes the GFCI feature.

The control console also ships with a detachable AC power cord. Because the console is not designed for use in a wet environment, its power cord does not include the GFCI feature. The control console will draw a maximum of 0.5 amps.

TESTING, OPERATION, AND ONGOING CARE

As mentioned in the previous section, we recommend testing the GFCI safety feature on the scoreboard display's AC power cord during the initial installation process. Afterwards, assuming the cord is in good condition, apply power to the scoreboard display first. Although there is no harm in powering the control console first, the illuminated digits and indicators on the sign will remain blank if the scoreboard display receives power before it receives data. Any LEDs that are illuminated on the sign in this condition would indicate a problem at the scoreboard display.

Next, power up the control console and, for wired setups, use a stereo patch cable to connect one of the console's data output ports to the data input port at the display. The scoreboard should begin showing data within a few seconds. Make sure buttons on the control console produce responses at the scoreboard display. You may need to consult the documentation that ships with the control console to test certain features.

For scoreboards with Clock features, set the Clock to count down the final 30 seconds of a Period. If your scoreboard includes a Horn, it will (by default) sound when the Clock reaches 0.

Scheduled Testing and Maintenance

Aside from regular testing of the GFCI portion of the AC power cord, the scoreboard system does not require scheduled maintenance procedures. However, it is important to check for problems prior to a game, practice, or other usage. We recommend running through the tests described above between two and four weeks prior to the start of a season (or anytime you plan to use the scoreboard after a gap of more than a month). During the season, test out the scoreboard the day before each game or practice session.

After the Game, and After the Season

Whenever you are not using your scoreboard system, unplug the power and data cables and store them. You should unplug the control console from its power source and from the data cable as well. While portable outdoor scoreboard displays are designed to survive under most weather conditions, we recommend moving the sign to a protected area when it will not be used for more than a few days. This precaution is aimed primarily at discouraging people from bothering the unattended sign.

MAINTENANCE

We hope your scoreboard system provides years of trouble free service. In the event of a problem, the material that follows will provide some information about contacting technical support as well as some details about the parts inside your scoreboard display.

Contacting Technical Support

Our support staff is available via phone or e-mail Monday through Friday 8:00 through 5:00 Eastern. Our web address and phone number is printed at the bottom of this page. When contacting Electro-Mech for support, it helps to have the scoreboard model (LX7620) handy as well as the version of the software running on your control console. If your control console includes an LCD display, you will see the software version flash briefly (for about three seconds) on the screen when you first apply power. Whether you have the LCD display or not, you should find on the bottom of the control console a product label which gives the software version.

If you are reading this manual in search of help with a different scoreboard model, for outdoor scoreboards, you can find the model number printed on a metal plate attached to the back of the scoreboard cabinet near where the power enters. For indoor scoreboards, the model number is usually printed on a label at the top center of the cabinet near the attachment point for the power cable.

If you are troubleshooting a problem, the most important information to have is an exact description of which parts of your scoreboard system are working and which parts are not working. The best person to make contact with our support team is someone who has seen the problem first hand. Better yet, give us a call when you are there at the scoreboard display and can walk through a few simple tests with one of our technicians.

Scoreboard problems are rarely so complicated that diagnosing them requires skills beyond using a screwdriver and a ladder. Similarly, replacing parts is straightforward process that does not require complex tools or special knowledge.

Parts Exchange

If, after working with our support staff, you discover that a part needs to be serviced or replaced, the next step is to send the part to Electro-Mech for repair. During the warranty period, we repair parts and return them via UPS ground service at no charge. We can ship parts via overnight service for an additional charge. For work that falls outside of the warranty terms, we can, upon request, provide an estimate of repair costs on returned parts before performing the work. The typical turnaround on repair work is less than three business days

Electro-Mech maintains a supply of common parts for immediate shipment. Some customers choose to purchase new parts for immediate use and will later send old parts back to us to be repaired and returned as "backup" stock. In some cases our support plans include the option for shipping replacement parts to the customer once our service staff has identified a problem. The customer will then return the damaged part after receiving the replacement. Electro-Mech requires a valid credit card number before initiating a shipment of this type. We do not apply charges to the card unless the customer does not return parts within ten days or if the returned parts require work outside of our warranty terms.

Our shipping address:

Electro-Mech Scoreboard Co. 72 Industrial Blvd. Wrightsville, GA 31096

Location of Serviceable Parts

All serviceable parts are located behind the Segment Count illuminated digit assembly. The next section of this document discusses removing and replacing illuminated PCB assemblies.

If your scoreboard system includes a ScoreLink wireless data kit, the receiver unit will be in the upper left corner of the display face, and the internal Horn will be mounted in the upper right.

Illuminated PCB Assemblies

The LED assemblies and circuit boards (but not individual LEDs) are field replaceable parts. Each LED is soldered to a printed circuit board (PCB) which is, in turn, attached to a protective metal mask. The mask assembly is attached to the scoreboard face with machine screws. You will need a 1/4-inch nut driver to remove these screws.

Removing an LED Assembly, Step-By-Step:

• Disconnect power to the practice segment timer cabinet before performing any service work.
• Remove the machine screws from the metal mask, leaving for last one of the screws along the top of the mask.
• Support the mask with one hand as you remove the final screw.
• Rotate the mask so that you can see the PCB (or PCBs) behind it and the cable connections along the back side.
• Unplug the ribbon cables, and, if present, the power cables from the PCBs.
• Set the LED assembly aside and save the screws for later.

If your purpose in removing the LED assembly was to provide access to the components behind it, you may skip the next part about removing and replacing the LED printed circuit board.

The LED circuit board is held to the mask by several nuts, which you can remove using a 3/8-inch nut driver. On outdoor displays the thick conformal coating can be messy, as the lock washers on the nuts dig into the coating and knock pieces of it away. Be careful to keep the whole assembly right side up when you return it to the practice segment timer cabinet.

Power Supply and Fuse

The AC power socket on the cabinet back is the point of entry for power at the scoreboard display. From this socket, the line side of AC passes through a 5-amp fuse on the way to the Mean Well RSP-320-24 power supply module. The fuse is AG style and should only be replaced with a fuse of the same style and rating.

Power connections are made along a row of screw terminals on one side of the power supply module. The Mean Well RSP-320-24 module provides 18.9 VDC to the illuminated digits and indicators along with the driver. If you replace a power supply module, check the output voltage to make certain it is set to 18.9 VDC.

LX Drivers

The LX Driver circuit boards do the work of interpreting data sent from the control console to the scoreboard display. Using that information, the drivers decide which of the LEDs should be illuminated and which should not. Each LX Driver in this system decodes data representing a specific set of digits or other indicators used in the scoreboard. The drivers send signals to the LED circuit boards via ribbon cables.

Data flows from one LX driver to the next in order, starting at the lower chassis (if there is more than one), and then left to right within each chassis. In the table(s) below, columns identify the LX Drivers, listed in order, left to right, based on the data path. The table rows give the names and purposes of the various connectors on the LX Drivers.
