Wiring

Testing

To ensure the wiring is correct, I've used several stages of testing. 

  • Visual inspection: make sure that each track section has a power connection, and comes from the correct wire. 

  • Isolation checks: remove the power connection from the return "blue" rails, and check they are electrically isolated from each other. (This picks up any rail sections that have been connected to the "wrong" return wire).

  • Short circuit check: use a coin to short each separate rail segment. Check that the power manager boards detect and isolate the short in one section only, and that the booster does not "beep" indicating a short that the power manager didn't handle.

  • Block detection check: use an LED to check that each section has power, and that the block detector reports this section (and only this section) as occupied to LocoNet.

If those tests pass, then the track has been wired correctly!

Using This Site

Searching

The web site can be searched: type a search term (e.g. "DAC10") into the search box on the right hand side of the header, and hit enter. the search engine will find words matching the search string in the main body of the site, but it won't search attached documents (e.g. the product manuals).

"Read More"

Many articles are displayed one after the other. some are quite short, and say "read more" at the bottom. Click that to read the remainder of the article.
