Alternate signal positioning
Rather than place the signals and sensors as shown on page 1 you may choose to locate the signals at the opposite ends of a
long section of track as shown below. All wiring should follow what has been previously described.
Please note that with
this usage of the
Block Animator/2
you CANNOT enable approach lighting; you MUST have the APPRL switch in the
OFF/OPEN position in order to have proper signal behavior.

Troubleshooting – photocell sensing
If your signals are not changing colors when the sensors are covered or stay red all the time you can perform the following tests.
First, verify that you have the sensor mode configured correctly (see Table 1 on page 3). Second, revisit the photocell sensitivity
adjustment process on page 4. A loose or missing wire connection on a photocell will cause its corresponding status LED to stay
on all the time!
Troubleshooting – Between-the-rails infrared sensing
If a signal is not changing colors when its associated sensors are activated or stays red all the time you can perform the following
tests. First,
verify the sensor wiring previously described
and verify the glow of the IR emitters using a digital camera or
smartphone camera. Also verify that you have the sensor mode configured correctly (see Table 1 on page 3). If the signal stays
red all of the time then disconnect that signal’s associated IR detectors blue wires. After two time delays the signal should return
to green. If it does then there is a problem with one or both IR detectors. If your signal never changes from green then
temporarily connect a wire between either of its detector input terminals and the GND terminal AND change the sensor mode to
External Detector (see Table 1 on page 3). The signal should immediately change to red. If not, then the
Block Animator/2
board should be returned to us for test/repair. If the signal did change to red then disconnect the temporary wire. The signal
should proceed through its delay and color changes. If so then the problem lies with the IR detector. Don’t forget to configure
the sensor mode properly again!
