If you wish to power the controller directly from a fixed voltage post on your transformer ( makes the uncoupler/ unloader section operate without powering up the track ) disconnect wire #4 from the track section and run it to the appropriate hot post.
Isn't it the #3 wire for fixed voltage?
Right you are! Sorry for the confusion.

Further study revealed #3 wire for fixed voltage on the "O" track section, whereas it is #4 wire on the "027" section. Here in lies the source of the confusion.
