To install the transducers with their correct mounting plate:
1
Be sure that you have on hand all the parts for two gating transducers and, if used, all
the parts for two advance transducers.
2
Be sure that you have on hand a track drill, a 3/8-inch bit, a 9/16-inch wrench, and a
50-foot (15-meter) or longer tape measure.

Determine the size of the rail at your site.
If your rail size isn't 115, 122, 127, 132, 136, or 141 pounds per yard (57.05, 60.52,
63.00, 65.48, 67.46, or 69.94 kilograms per meter), call STC for help.
On the rail nearest to the bungalow, you'll next install the gating transducer nearest to
the bearing scanner. This transducer is
TO1
.
