The "red time" can be adjusted to a realistic duration for a train to clear the section of
track protected by the signal.
The "yelllow time" can be adjusted to a realistic duration for the scale.
When supplied, or following a factory reset, the module will operate in 4-aspect
mode. It needs to be reprogrammed as follows.
To select this program, switch off the power to the module and hold down the Push
Button. Apply the power and continue holding the push button until
2 flashes
are
seen. At this point, release the button. You will see a long flash of two seconds and
then the led will begin flashing again.
When
3 flashes
have been seen press and hold the button. You will see a long flash
of five seconds and then 10 rapid flashes. The button can now be released and the
programming is complete. The module will start running the program. If you make a
mistake programming, simply repeat the process.
Program 4 (4-Aspect Signalling)
This program simulates the operation of a four aspect signal, which is normally
showing green. The module searches for a train, and if one is detected in front of the
sensor, the signal immediately switches to red.
Whilst the sensor is covered, the signal stays at red. As the train passes over the
sensor, any gaps between the rolling stock which are shorter that the release time
programmed are ignored.
