22.1.2 UR90/UR91Track Status Indicator Hook Up
Note: Hooking up the UR Track Status Indicators is OPTIONAL
The UR Track Status Indicator is a bi-color LED that shows the status of the
local track section to which it is attached.
1. Attach an 18-26AWG wire to one of the screw terminals on the back
of the UR & connect the other end to either rail.
2. Attach another 18-26AWG wire to the other screw terminal on the UR
& connect it to the other rail of the track.
3. If you are hooking up more than one UR or UP, be consistent in hook-
ing up all track sections alike with respect to which terminal is con-
nected to which rail. This is not required but strongly recommended.
As you operate your layout, the UR Track Status Indicator will be lit when the
track is powered. The LED will glow red or green when you are operating an
analog locomotive and the system is "zero stretching." When you are using
DCC only, the LED will glow orange. This color change is a useful diagnostic
tool.
