In both locations, I use an OnGuard Auto Reverser. The auto reverser is connected just to the tail track, the wye switch, and a few inches of wye leg tracks. The Oakridge installation has been working flawlessly for a couple of years. Why would the new installation at Cascade Summit not work?
I did continuity checks, voltage checks, using an RRampmeter (DCC voltage and ammeter) and tried bringing the power for the wye tail section from the nearby wye base and leg circuit rather than a separate pair of leads from the station panel terminal block. I even tried reversing the power leads to the auto reverser. All that did was change the leg of the wye that would work. A board swap, prompted by the DCC Specialties folk just had the Oakridge installation still working and the Cascade summit installation not working.
I finally took note that the PSX circuit breaker for Cascade Summit would trip, showing a short, but the auto reverser would not trip. That was the major clue as to what was going on. The PSX was tripping faster than the OnGuard auto reverser for the Cascade summit Installation. I checked the PSX circuit breaker instructions to see if there was a way to change the circuit breaker timing. No such luck in the instructions. I consulted with my DCC experts. They at least confirmed I likely was on the right path dealing with circuit breaker trip time.
I did note a slightly different form factor (board width) and a couple of other detail differences between my older PSX circuit breaker boards and the much newer ones installed for Cascade Summit. I also noted a change in the instruction package for the PSX between my earlier breakers and the new ones. Something had changed. Finally, a desperate e-mail to DCC Specialties, sent over the weekend, netted instructions on setting the PSX trip time. Kudos to them for a Sunday response!!!!
After considering my options, I elected not to change the PSX circuit breaker trip time. I will reserve that for the future, should I encounter further problems. Instead, I swapped the old PSX boards at Springfield (my original installation) for the boards at Cascade Summit and McCredie Springs. The combination of the old PSX boards works with the OnGuard Auto Reverser. I now have that set up at both Oakridge and Cascade Summit. It works!!!
The pictures below will show ways to identify the various circuit boards on my layout.
