Operation

With the power switched on, the red led on the PCB should flicker rapidly and the
signal should show clear (green).

If a train now passes over the sensor, or you wave your hand close to the sensor,
the signal will switch to danger (red).

The PCB led now flickers at a slower rate, and this indicates that the module is now
looking for the end of the train to clear the sensor. Gaps between carriages of up to
4 seconds are ignored (see the programming section below if you want to adjust
this).

Once it is determined the train has completely cleared the sensor, there is a final
short delay (also programmable if you wish) before module switches back to clear.

With 3- and 4-aspect signals the intermediate states of yellow and double yellow will
be shown. The timings for these states are also adjustable if required.

Programming

The module will operate the signal straight out of the packet.

The default program is to operate a 4-aspect signal, so if you connect a signal with
fewer aspects it will be necessary to reprogram the module.

Programming is performed holding down the Push Button when switching on the
power and counting the number of flashes of the led on the module. Full
programming details are given later in this document.
