L1DC AUTOMATIC TRACK LOOP CONTROLLER.
Manages trains entering a track loop
Operates points to route arriving locos to vacant track
Holds locos until another arrives, stops them for a set delay, or the user can release them
Flexible design can easily be programmed to suit user requirements
Basic Operation
The module is connected to the points motors at both ends of a section of track with a loop.
Each of the two lines has a section isolated either by insulated track joiners or breaks in the track.
This section is normally not energised and so any train reaching this section will come to a stop.
Two infra-red sensors are connected to the module that detect trains entering either the loop (L),
or the main section of track (M) depending on the setting of the points. Only one sensor is active at a time.
When the module is powered, it switches the points to their last know position (from when the module was last switched off).
When a train arrives, it crosses the points and passes over one of the infra-red sensors and comes to rest at the isolated track section.
The module operates the points at both ends of the section ready to depart any waiting train on the other line and after a delay,
energises the isolated section allowing any waiting train on the other line to depart.
The train which has just arrived, remains at its isolated section, until another train arrives on the opposite line, when the process is repeated.
There are many options to customise the operation which are covered in detail PDF file.
