9. Perform the same beam location technique at the mph and finish line locations. After all
detectors and mounts have been located, it is best to cement the bracket bases so that they do not
move in the ground.
10. The wiring of the track can now begin. There is one main cable that goes to the starting line and
tree. Locate the gra y interface box in the tower a nd run the main wire out to the center of the track.
All conne ct ors ar e labele d and can b e routed to their r es pect ive loc ati ons . The C hri s tm as t re e can be
located and connected to the starting line 25 pin male connector. If you have a professional tree, the
cable will run directly out to the tree. There is 40 feet of wire from the Christmas tree so that it can
be moved up to forty feet in front of the starting line. It should be out at least 25 feet and many
tracks are now out 40 feet.
11. Next locate the mph junction boxes if you have them. If you do not have these junction boxes,
your wire will be located down the center of the track. These junction boxes should be located at the
finish line on the outside of the track and have enough wire to move them off the edge of the track.
We have a 12 position terminal strip inside which contains the wires for the mph and finish line
detectors as well as the win light, stop light and spare wires for that lane.
12. There are two lengths of wire that will be used to reach the finish line on both sides of the track .
The longer length is for the far lane and the shorter length is for the near lane to the tower.
Sometimes we ship one continuous length of cable. Always start at the furthest point from the tower.
NOTE: Item 13 is for tracks that have the wi re run n i ng d own th e si des of th eir trac k an d who are
utilizing MPH/Finish junction boxes.
13. The junction box has a wiring schematic under the cover. The wires should be bared back about
¾ inch twisted and folded over and twisted again and then soldered. Make the solder joint small
enough to get into the te rminal strip and then fasten with the screw. The drain wire (bare wire) can
be attached separate terminal if supplied. At the finish line, you will need a relay to power you win
lights. It should not draw more than 40 milliamps at 12 volts. We recommend a solid-state relay
like a Grainger part#: 5Z946 or 5Z948 rated at 10 Amps or part#: 5Z956 rated at 25 Amps, but a
radio shack catalog # 275-248 relay will work for win lights and is rated at 10 amps and 125 volts
ac. Use a perforated board cat# 276-1395 to mount the relay on. Run a wire out of the finish line
junction box to the relay. Do not mount the relay in the junction box.
14. The other end of each of these wires is to be terminated in the tower inside of the interface box.
Wiring is as follows:
RED AND BLUE WIRE POSITIVE 12 VOLTS D.C.
BLACK AND WHITE WIRE GROUND 12 VOLTS D.C.
BROWN AND GREEN WIRE SIGNALS TO TERMINAL STRIP
BROWN IS MPH GREEN IS FI NISH
GRAY WIRE WIN LIGHT GROUND SIGNAL
PINK WIRE POSITIVE 12 VOLTS D.C.
ALL SPARE WIRES TO GROUND
IF USING STOP LIGHTS:
ORANGE WIRE STOP LIGHT GROUND SIGNAL
YELLOW WIRE POSITIVE 12 VOLTS D.C.
15. The time slip printer can be located up to 1,000 feet away. We can provide a custom cable for the
time slip printer.
