Chapter 9
Placing a System into Service
This chapter describes some of the final things that need to be done before placing a
SmartScanIS into service.
9.1 Checking the Trackside Components
To check the correctness of the installation of the trackside components:
1
Be sure that you have on hand a tape measure, a 9/16-inch torque wrench, and the
alignment fixture.
2
At trackside, check track conditions on all tracks.
3
If any track is pumping (vertical displacement of the rails) or running (lateral
displacement of the rails) more than 2 inches (5 centimeters), have it repaired before
proceeding.
4
At trackside, check that all the track-mounted hardware has been installed properly.
5
If any piece of the track-mounted hardware isn't installed or isn't installed properly,
install it properly before proceeding.
Chapter 6 - Installing the Track Components
tells how to install the scanners,
transducers, a track circuit, and AEI antennas. Trackside installation of
dragging-equipment detectors and other auxiliary-alarm detectors isn't covered in this
guide.
6
At trackside, check all transducer-mounting bolts on all tracks to make sure that all
transducers are snug against the rail.
Four bolts are needed to hold the transducer in place. Two square-head bolts go
through the mounting plate and transducer body. Two hex-head bolts go through the
mounting plate and rail. If any of these bolts are sheared or missing, they must be
replaced with the correct replacement bolt. Also, if any washers or nuts are missing,
they must be replaced.
7
If all transducers aren't snug against the rail, fix this problem before proceeding.
Each installed transducer body should be 1-9/16 inches (3.97 centimeters) below the
top of the rail and parallel to it. You can meet this requirement by using the transducer
height bracket on the bottom of the alignment fixture.
8
Place the alignment fixture across both rails, centered over each transducer in turn.
