flashes for 10 seconds).
When the button is released, the led flashes 10 times rapidly, and the module starts
operating.
Other Programming Options
There are a number of parameters which can be adjusted if you wish to alter the
operation of the module.
Release Time
This is the time that the infra-red sensor must be continuously unobstructed for the
module to confirm the train has passed. This allows for gaps between the carriages
of variable reflectivity of the underside of the train.
The default setting is 2 seconds. A value of between 1 and 255 seconds is possible.
Lamp Fade-Down Rate
This is the rate at lamp (leds) dim down.
The default setting is 3 which represents the appearance of a filament lamp. If the
effect of an led aspect is required, then set this to 9.
Lamp Fade-Up Rate
This is the rate at lamp (leds) brighten when switched on.
The default setting is 4 which represents the appearance of a filament lamp. If the
effect of an led aspect is required, then set this to 9.
Maximum Led Brightness
The leds are normally set to operate at full brightness, with this set to 7.
This value can be reduced if the leds appear brighter than required.
Gap Between Phases
This variable set the gap between each aspect switching, to represent the operation
of relay interlock.
The default value is 2. This variable can be set from 1 to 9.
