MECHANICAL INSTALLATION

The mechanical installation includes installing the posts and mounting the model 3050 and the optional top sponsor panels (if purchased) to the posts.

Post Installation The model 3050 delay of game timer mounts on two posts. Typically installers will use steel pipes or I-beams. In order to reduce the glare from the sun on the LED digits, position the posts so that the front of the cabinet is angled away from the afternoon sun, if possible. The mounting hardware will accommodate posts up to 4.5 inches outer diameter. Sink the posts in reinforced concrete footings. Figure 1 shows the spacing of the posts for a 3050 delay of game timer. The specifications for the posts and concrete footings are dependent upon the expected local wind and soil conditions, the height of the product from the ground, and the local building codes. Electro-Mech Scoreboard Company assumes no responsibility for the installation of products by others.

Figure 2 shows the spacing of the posts for a model 3050 with an optional side sponsor panel. The sponsor panel is built into the cabinet.

Mounting The Model 3050 Delay of Game Timer The product is attached to the posts at four points. Figure 3 shows the location of the mounting points on the rear of the cabinet.

MOUNTING HARDWARE

Four sets of mounting hardware are provided to attach the model 3050 at these points. A single set of mounting hardware for the unit 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 model 3050 attached to a post at a mounting point. A steel bar is riveted inside the product’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 unit in place.

The following steps describe how to mount the model 3050 on the posts: 1.Place the 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 cabinet. 3.Place a steel angle bracket over the threaded rods at mounting point #1. 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 3 - 6 at the other mounting points. 7.Raise the cabinet into place and tighten the nuts to clamp the cabinet in place on the posts.

ELECTRICAL INSTALLATION

We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the product. These connections include grounding the cabinet, connecting the product to a power source, installing the SL-320 or the control cable, and connecting the control console.

Ground Connection The National Electrical Code requires this product (an electric sign) to be grounded. Grounding the cabinet helps the 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” x 8’ copper clad ground rods in the soil near the model 3050. 2.Connect #6 bare copper wire to the ground rods using 5/8” brass tear drop connectors. 3.Remove the rear access panel and the dome plugs on the plate below the access panel. Figure 5 shows the location of the access panel and the dome plugs.

5.Pass the ground conductor through the right hand hole in the plate below the access panel and connect it to the ground lug (Ground) on the junction chassis.

Install a power disconnect that isolates all current carrying conductors on one of the posts below the cabinet (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 model 3050 from lightning damage. A power disconnect on the mounting post also provides a convenient way of turning the model 3050 off during maintenance or repairs.

SL-320 The SL-320 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 outdoor LED products. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the SL-320 OWNER’S HANDBOOK for installation instructions.

Serial Data Output Connections Customers who have purchased a set of delay of game timers can provide the other delay of game timer or a scoreboard with serial data from this delay of game timer. This connection is an alternative to providing serial data from the control console via the control cable or a SL-320. The following steps describe how to transmit serial data from this delay of game timer to the other delay of game timer or a scoreboard: 1.At the rear of the delay of game timer, feed data cable (same type of cable specified for control cable on page 3) through a hole in the plate below the access panel. 2.Crimp fork terminals to the cable wires and the shield. 3.Connect the cable to the terminal block labeled Serial Data Output on the junction chassis according to figure 8.

8.Reinstall the other delay of game timer or scoreboard rear access panel.

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 10 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 delay of game timer: 1.At the rear of the model 3050 cabinet feed the control cable through the left hole in the plate below the access panel. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to Control Cable terminal block on the junction chassis according to figure 11.

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.
