If a signal is showing a diverging aspect, the signal preceding it will not show 'clear.' A preceding double-head signal will
show 'approach medium' or 'approach slow.' A single-head signal will show 'approach' or 'advance approach.'
"Speed Signaling" systems
are used by some railroads instead of the Route Signaling described above. Rather than giving
turnout direction information to the train crew, speed signaling uses multiple heads to indicate maximum allowable speed,
usually through a control point. The upper head indicates Normal speed, the second head indicates Medium speed, and if
there is a third head it indicates Slow speed.
What if your signal structure has a dual head signal in a place where your track configuration shows a single head signal?
You can wire the lower head for a permanent red indication. Only the 'R' wire needs to be connected to the lower head.
Signal test button
Check signal operation
with the 'test' button. The button is very small, it is best to use the eraser end of a pencil or other
non-conductive tool to press it.
1.
Hold the test button down for 2-3 seconds until the
yellow on-board LED 1
starts flashing. Release the button. Signal 1
upper head should show 'clear,' all others signals will be dark.
2.
Press and release the button. If the '4a' config jumper is in place the signal will change to
'advance approach,' otherwise it will show 'approach.'
3.
Repeat pressing the button for 'approach' and 'stop.'
4.
Press again. If the lower head of signal 1 is connected, repeat the above steps to show
'diverging clear,' 'diverging approach,' etc.
5.
Press again and the
yellow on-board LED 2
will flash. Repeat the above steps for Signal 2.
6.
Press again and the
red on-board LED 3
will flash. Repeat the above steps for Signal 3.
7.
Press again and the
red on-board LED 4
will flash. Repeat the above steps for Signal 4.
8.
Press again and the
yellow LED 1 and red LED 4
will flash. Repeat the above steps for
Signal 5.
To end the test sequence early at any time, hold down the test button until the on-board
LEDs stop flashing.
When the on-board LEDs stop flashing, the TS5 is back to normal operation.
