SCOREBOARD INSTALLATION

The MP-320 Delay of Game Timer units are typically installed in or behind the end zones of the football field. Typical installation of the MP-320 consists of positioning the posts, mounting the units on the posts, and making the proper electrical connections. Note: Installation of a unit on a wall will force a service technician to remove the unit from the wall in order to remove the plug in module inside the unit for repair.

Items not provided by Electro-Mech Scoreboard Company which are necessary for installation:

Four posts
Power cable to connect each unit to your power source
Grounding hardware
A grounded NEMA 5-15R 120 VAC receptacle for the control console.

Items not provided which are recommended by Electro-Mech Scoreboard Company for installation:

A weatherproof power disconnect at each unit
A weatherproof NEMA 5-15R 120 VAC convenience receptacle at each unit

While Electro-Mech Scoreboard Company does not perform installations, we will make every effort to answer your installation questions. Installation should be performed by qualified personnel. Consult national and local codes before installation.

POSITIONING THE POSTS

Each unit is designed to be mounted on two posts. We suggest that the front of each unit should angled away from the afternoon sun, if possible. Typically installers will use steel pipes or I-beams. The mounting hardware will accommodate posts up to 4.5 inches outer diameter. We recommend that the posts are sunk in reinforced concrete footings. Figure 1 shows the spacing of the posts for a MP-320. It suggests one possible installation for a MP-320 in silty sand soil. No dimensional data in this manual is intended to be specifications except the size of the unit cabinet and the distance between the posts. 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.

MOUNTING HARDWARE

Four 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 3 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 steel bracket is riveted to the scoreboard’s aluminum extrusion frame. The bracket 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.

MOUNTING THE SCOREBOARD

The scoreboard is attached to the posts at four points. Figure 4 shows the location of the mounting points on the rear of the scoreboard.

Figure 4 Mounting Points — Mounting Points — Figure 4 Mounting Points Labelled: Mounting Points

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 4 -6 at the other mounting points. 7. Raise the scoreboard into place and tighten the nuts to clamp the scoreboard in place on the posts.

ELECTRICAL CONNECTIONS

We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of your scoreboard. These connections include grounding the scoreboard, connecting the scoreboard to a power source, installing 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 when they are placed in concrete. One method of grounding is to connect the scoreboard cabinet to one or more grounding rods which are driven into the ground near the scoreboard via a large gauge copper wire. The self tapping sheet metal screws on the back of the scoreboard cabinet provide a convenient connection point.

Connecting The Scoreboard To Your Power Source The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model MP-320: 600 Watts. Make sure that power cable is rated for this electrical load. Electro-Mech Scoreboard Company recommends that your power cable is installed in conduit. Avoid running your power cables in close proximity to your control cable. The following steps describe how to connect the scoreboard to your power source:

1. Remove the hex head screws which hold the rear upper access panel in place (Figure 5).

Figure 5 Upper Access Panel — Rear Access Panel, knockouts — Figure 5 Upper Access Panel Labelled: Rear Access Panel · knockouts

Figure 6 Access Panel Removed — MST-01, 1/2 A 8A, S3, F1, F2, T2, T3, T1 — Figure 6 Access Panel Removed Labelled: MST-01 · 1/2 A 8A · S3 · F1 · F2 · T2 · T3 · T1

2. Punch out the knockouts for the power and control cables.

3. Feed the power cable through a knockout.

4. Connect the AC line wire to position 1 and AC neutral wire to position 2 of terminal strip T3 on the junction chassis according to figure 7.

Figure 7 Power Connections — Position 1: AC line (hot) wire from your power source, Position 2: AC neutral wire from your power source — Figure 7 Power Connections Labelled: Position 1: AC line (hot) wire from your power source · Position 2: AC neutral wire from your power source

Electro-Mech Scoreboard Company suggests that you install a power cut-off switch and a NEMA 5-15R receptacle in a weatherproof box on the scoreboard post below the scoreboard. The cut-off switch provides a convenient way of turning the scoreboard off during maintenance or repairs. The NEMA 5-15R receptacle will allow a technician to easily plug in the control console and operate the scoreboard via the test jack S-3(a valuable trouble-shooting aid).

ScoreLink 300 The SCORELINK 300 RF MODEM SET is intended 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 option, disregard the next section of this manual. Refer to the SCORELINK 300 RF MODEM SET OWNER’S HANDBOOK for installation instructions.

Installing The Control Cable The control cable connects the scoreboard to the control console. While the control cable is direct burial rated, Electro-Mech Scoreboard Company recommends that it is installed in conduit to protect it from being cut. A small junction box with a 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 match their stereo jack to one of the stereo jacks in figure 8 in order to make the proper connections. These connections should be soldered.

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 below the access panel. 2. Crimp fork terminals to the control cable wires and the shield. 3. Connect the control cable to terminal strip T1 (located to the left of the test jack S3) according to the diagram in figure 9.

Connecting The Control Console The control console is normally connected to the junction box via the 10 ft. extension cable. This extra length of cable allows the scoreboard operator some mobility and the ability to store the control console after the game. The extension cable has two molded stereo plugs attached to it. One end of the extension cable is plugged into the junction box stereo jack and the other end is plugged into the stereo jack mounted on the control

console back plate. The control console power cord is plugged into a grounded NEMA 5- 15R 120 VAC receptacle.

SCOREBOARD OPERATION

The MP-320 Scoreboard is normally operated at a site with a football scoreboard. If you have a Electro-Mech Scoreboard Company MP series football scoreboard, the MP-320 scoreboard can be programmed by that control console and operated by a hand held unit. If you do not have a MP series football scoreboard, it can be programmed by its own control console and operated by a hand held unit which interfaces with the control console. No scoreboard functions will operate without connecting the control console. Figure 10 shows the keypad layout on your control console. The keypad functions are described in the text below the figure.
