ELECTRICAL INSTALLATIONWe recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the shot timer. These connections include connecting the shot timer to a power source, installing the SL-230 / 330 RF modems or the control cable, and connecting the control console. Power Connection The shot timer requires 120 VAC service at the shot timer to operate properly. Maximum power consumption of Model 2160: 40 Watts. The shot timer has a 6 ft. attached power cord located at the top of the cabinet. Plug the power cord into a grounded NEMA 5-15R receptacle. The receptacle should be controlled by a separate circuit breaker so that the shot timer can be turned off without turning off other electrical devices in the facility. Figure 4 shows the electrical connection points on the scoreboard. Units built before August 2007 do not have a CPC receptacle.
The SL-230 / 330 RF MODEM SYSTEM is intended to eliminate the control cable between the scoreboard and the control console on indoor 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. Two sets of transmitters and receivers programmed on different channels are required for this scoreboard. Refer to the installation manual provided for this product.
Control Cable Installation If the customer is operating a scoreboard with the same control console as the shot timer, he can install the control cable from the ¼” stereo jack mounted on the top of the shot timer to the shot timer output jack located on the right side of the scoreboard, or the serial data output jack located on the top of four sided LED scoreboard models, or to the control console. A connection to the control console is preferred. When connecting between the shot timer output jack of the of the scoreboard to the model 2160 shot timer, each end of the control cable has a ¼” stereo plug attached. When connecting between the control console and the model 2160 shot timer, the cable end that attaches to the scoreboard has a ¼” stereo plug attached and the other end has a small metal junction box with a ¼” stereo jack mounted on the face plate. The junction box should be securely mounted within 10 feet of the control console point of operation. A 10 ft. cable with ¼” stereo plugs attached to each end (called the extension cable) is provided to make the connection from the junction box the control console. Most customers order the control cable with the proper connectors attached to each end when ordering the shot timer. Some customers prefer to attach the connectors after the cable is installed. The instructions below describe how to attach these connectors. All connections should be soldered. Splicing the cable is not recommended. Figure 5 shows the connection points to solder the ¼” stereo plug to the control cable. Unscrew the stereo plug cover from the plug body to expose the contact pins. Figure 6 shows the connection points to solder the control cable to the rear of ¼” stereo jack mounted on the face plate of the junction box.
The 10 ft. extension cable has two molded ¼” stereo plugs attached to it. The following steps describe how to connect the control console:
Control Console Safety Warning This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type plug.
