§
Connect the transformer only to an approved mains socket installed
by an authorised electrician.
§
Make no changes to the original parts and accurately follow the
instructions, circuit diagram and PCB layout included with this manual.
§
Use only original spare parts if you have to repair the kit or the
ready-built module.
Operation overview
In two-rail systems opposing electrical poles collide at the points into a
loop. This causes a short circuit when the points are passed by a
locomotive if no measures are taken to prevent it.
The loop module is controlled by an IC that permanently supervises the
voltage on the rails within the loop. The IC detects a short circuit which
may occur when a locomotive gets into or out of the supervised section.
The direction in which the locomotive is moving within the loop is not
significant.
When a short circuit occurs, the voltage decreases below a defined
value and the IC switches a relay to reverse the connections (and
thereby also the polarity) to the rails within the loop. This way the short
circuit is neutralized.
The rail section within the loop should be separated from the remaining
tracks. It is powered by the loop module.
The module may only be used in digital controlled two-rail model
railway.
