Auto Reverser (s)
|
Ted Atkinson
Had used a Digitrax AR1 Auto Reverse Controller, prior to upgrading bus to 14 gauge from 16 gauge, on one reversing section and it worked fine. Now it allows locos thru one end of the loop but shorts the system at the other end. Tried reversing the wiring into the reverser and the problem is solved at one end of the loop but not the other (ie the short is now at the other end of the loop). I substituted a tam valley dual frog juicer, adjusted for reverse loops and it works fine. Unfortunately, I have several of the Digitrax units and would prefer to get them working without buying another Tam Valley unit. Any suggestions would be appreciated Thx, Ted |

What else changed in your system Ted?
Maybe new Booster? New Short Detection? (add a PSX-1 or
other?)
anything?
I know for me.. and the HMRC (Housatonic Model Railway Club)
layout.. I had a great many AR's in PSX-1 districts - without a problem... and
without me having fully read instructions on the PSX-1 or AR's in use layout
(many different AR Mfg's)
Everything worked great.. till one day we finally got to using the
Wye in one Yard.. and the Wye would not work correctly.
Long story short I had to adjust the CV setting in the PSX-1 for
longer delay for the AR to trigger correctly.

Maybe swap in a different AR1? It's possible the relay contacts
are welded in the unit, and it's unable to properly switch
states. Or, the circuit is fried completely, and unable to
energize the relay. I threw out one last year, as it failed to
operate at all even when swapped into a location where another one
had been working fine. Blair On 6/21/2021 3:00 PM, BillMellott

Ted,
It sounds like your AR1 is not reversing when it should. I think it is adjustable. Try adjusting it. Allan Gartner Wiring for DCC |

Thx for everyone's input. Tried a different one and it worked! I guess the other one has become faulty and cannot likely be fixed. Would still appreciate hearing from Alan as to how they are adjustable, just in case this is the issue. Thx again, Ted |

Ted,
Marcus posted a link to the Digitrax AR1 manual. On it, you will see the adjustment. Allan Gartner Wiring for DCC |

I have a query on a turntable AR - I have installed a Diamond Scale Models turntable with a Tam Valley Dual frog juicer - wired as per instructions but my locos will enter/exit the approach tracks and the roundhouse tracks from only one end of the turntable - from the other end they create a short circuit.
Any suggestions on this? Thx Dan Atkinson |

Confirm that the frog juicer is set to trip at lower current than any circuit breaker you have protecting the overall circuit and that the frog juicer is a dual frog juicer working both rails of turntable.
