PortaTree Eliminator Sand and Dirt Tracks - Manual

ELIMINATOR 2000 TRACK SYSTEMS
INSTALLATION PROCEDURE FOR 300 FT SAND DRAG TRACKS
1. Unpack all of the equipment and immediately inspect for shipping damage. Damages should be
immediately reported to the carrier and noted on the carriers receipt. Hidden damage should be
documented and shown to the carrier’s representative. Portatree is not responsible for damage by
shipping carriers and we cannot make claims from our end. Check the contents and match up to the
invoice and packing list.
2. The first track function is to layout the track. The starting line should be selected and temporarily
marked. The starting line will consist of a pre-stage, stage, and guard beam detector in each lane.
The pre-stage (you may not have a detector, but your cable has a cable end for pre-stage) is 7 inches
before the stage beam and the guard beam is located 15 inches in front of the stage beam line (some
sand drag tracks have the guard beam up to 18 inches in front of the Stage Beam). The guard beam
location is the starting line and all down track detector locations should be measured from the guard
beam line. NOTE: If you are not using your pre-stage and intend to leave the cable outside,
Please keep the cable end cover securely with plastic to keep water from entering the
connection and shorting it out.
3. The 60-foot mark and detector location should be measured from the guard beam mark – 60 feet –
or 61 feet 3 inches from the stage beam location. After laying out a temporary line at the 60-foot
location, you should square up the starting line and 60 foot location by measuring the diagonals.
Even though you may not be using a 60-foot mark, it is a good idea to permanently mark the track.
4. When the starting line is permanently marked, you can then permanently mark the 60-foot
location and by measuring down each side of the track with the same measuring device, mark the
234 (M.P.H.—66 foot trap) and 300-foot locations (most sand drag tracks utilize a 10 foot M.P.H.
trap so you will be marking the 290 foot location). All measurements are from the guard beam
imaginary location or 15 inches in front of the stage beam location. Permanently mark the track for
future reference.
5. After the entire track is permanently marked, you can begin locating the detectors. You must
center these units on the marked line and do the same with the reflectors. Some tracks have the
detectors in the middle of the track, and some on the outside of the track. Usually if you have
purchased a MPH/finish win light junction box, you are mounting your detectors on the outside of
the track. In this case your reflectors will be in the middle of the track.
6. All mounting stands and brackets should be made of very rigid material so as to resist vibration
and flexing. The starting line receivers will be mounted in the center of the track, back to back with
plenty of adjustment for moving the detector up/down and left/right. Emitters will be mounted on
the outside of the track at the starting line and should also have plenty of adjustment to align to the
detector.
7. The 60 foot detectors will be mounted in the center of the track (or outside of the track if you have
specified) and the reflectors will be at the edge of the track. Again you must allow for adjustment to
align to each other.
8. Run a pull line tight across the track. The pull line should be 2 inches off of the track surface at
the starting line, and 6 inches off at all other locations, all the way across the track surface. The
center of the detection beam should be located on the center of the pull line. The reflector must also
be on this centerline.
