8.4 Wheel Scanners
Not all sites use wheel scanners. If your site doesn't use them, skip the instructions below and
go to
8.5 Gating Transducers .
If your site uses them, there are two wheel scanners per track.
At double-track sites, the cables from the wheel scanners on track1 are connected to the box
connectors in the leftmost SmartScanIS enclosure. The cables from track2 are connected to
the box connectors in the rightmost SmartScanIS enclosure.
To connect the Type II/Type III wheel scanners to the SmartScanIS enclosure:
1 Be sure that both wheel scanners are installed on the track.
At a single-track site, the cable from the wheel scanner on rail1 should be labeled
W-RAIL1 . The cable from the wheel scanner on rail2 should be labeled W-RAIL2 . If
the track runs north and south, RAIL1 is the east rail and RAIL2 is the west rail. If the
track runs east and west, RAIL1 is the north rail and RAIL2 is the south rail.
At a double-track site, they're labeled W-RAIL1-TRACK1 , W-RAIL2-TRACK1 ,
W-RAIL1-TRACK2 , or W-RAIL2-TRACK2 , whichever is appropriate.
2 Plug the connector from the wheel scanner on rail1 (that is, from the north or east rail)
into the third box connector on the Scanner Interface board.
3 Plug the connector from the wheel scanner on rail2 (that is, from the south or west rail)
into the fourth (bottom) box connector on the Scanner Interface board.
4 If this is a single-track site, go to 8.5 Gating Transducers .
5 If this is a double-track site, repeat steps 1 through 3 on the second track and then go
to 8.5 Gating Transducers .
