ELECTRICAL INSTALLATIONWe recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the softball timer. These connections include grounding the softball timer, connecting the softball timer to a power source, installing the horn (if purchased), installing the SL-230 / 330 or the control cable, and connecting the control console. Ground Connection The National Electrical Code requires a softball timer (electric sign) to be grounded. Grounding the softball timer helps the softball timer 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 softball timer to the power source:
Power Connections The softball timer requires 120 VAC service at the softball timer to operate properly. Maximum power consumption of Model 1064: 48 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 softball timer to the power source:
Install a power disconnect that isolates all current carrying conductors on one of the posts below the softball timer (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 softball timer from lightning damage. A power disconnect on the softball timer post also provides a convenient way of turning the softball timer off during maintenance or repairs. Horn Installation The items provided to install the horn are the horn, the mounting bolt, and the mounting bracket. Items which are not provided but are necessary for proper installation are ¾” conduit, a two ¾” male conduit connectors, a ¾” straight male conduit connector, two wires, two forked crimp terminals, and two butt splice connectors. The electrical requirements for the horn are 0.35 A 120 VAC. The horn is mounted to the right side of the softball timer. If a horn was purchased with the softball timer, a tapped hole is provided to fasten the horn to the softball timer. The mounting bolt is screwed into the tapped hole at the factory. The following steps describe the assembly and mounting of the horn:
10. Splice the horn wire leads to the two wires that run through the conduit with the butt splice connectors. 11. Screw the conduit connector into the threaded hole on the weatherproof back box. 12. Attach the horn and horn projector to the weatherproof back box using the four screws. 13. Fasten the horn assembly to the softball timer using the mounting bolt from the softball timer. 14. Crimp forked terminals on the ends of the two wires that protrude out of the other end of the conduit. 15. Pass the wires through one of holes in the bottom of the softball timer cabinet. 16. Fasten the conduit connector to the plate and connect the wires to the Horn terminal block on the junction chassis. Connect the AC-L wire to the left terminal and the AC-N wire to the right terminal. SL-230 / 330 The SL-230 / 330 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 installation manual provided for this product. Control Cable Installation The control cable connects the softball timer to the control console. Customers who are adding a model 1064 softball timer to a field with a compatible softball / baseball scoreboard must either disconnect the control cable from the softball / baseball scoreboard and either connect it to the model 1064 softball timer or install new control cable from the control console to the model 1064 softball timer. 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 softball timer. 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 7 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 softball timer:
Serial Data Output Connections Customers who are adding a model 1064 softball timer to a field with a compatible softball / baseball scoreboard must install a cable to send data from the model 1064 softball timer to the softball / baseball scoreboard (unless a SL-230 / 330 system is installed). Do not splice the existing control cable that is connected to the softball / baseball scoreboard in order to send data to the model 1064 softball timer. Do not connect two control cables to the junction box ¼” stereo jack. Do not connect a cable from the softball / baseball scoreboard Control Cable terminal block to the model 1064 softball timer Control Cable terminal block. The following steps describe how to transmit data from a model 1064 softball timer to the softball / baseball scoreboard:
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:
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.
