programming my PSX-AC

On J6, connect 1 and 2 together, and also connect 3 and 4 together for 15 amp trip.

OR just 1 and 2 together for 8 amp trip OR just 3 and 4 together for 12 amp trip.

On J7, connect a momentary, normally closed, spst pushbutton across 1 and 2.

Pushing J7 will be your reset if it trips out with a short or overload.

If you have any EOB cruise control engines set your current limit to 12 amps to avoid unwanted current trips(this is due to the large current spikes EOB uses at very low speeds, the PSX is that sensitive).  As Chuck stated above, it's really easy.

Here is my cheat sheet for wiring my PSXs.  All the info I got from other forum members; if my memory was better I'd list them.

The lighted switch does two things:  LED comes on during a short and resets the PSX.  I have also installed Digikey's Sonalert on the PSX's circuit board as an alarm for when a short happens.  The Digikey part number is 458-1005. 

Thank you all.  Can anyone suggest a retailer for the additional jumpers, spst push button, Digikey, etc?  

You need nc or normally closed momentary push button.

The jumpers are just wires...bare is ok...formed in the shape of a staple.

On the advice of members of this forum, I purchased a PSX circuit breaker for my layout, but as I am not an electrical engineer, I really have no idea how to program it -- or whether I need to program it in the first place.  The instructions are confusing -- mostly because I don't have a good frame of reference to understand the terminology.  Can anyone give me a "PSX for dummies" explanation about how to set it up? (I know where the power input and output connections are but that's about it.)  Do I even need to do anything special if all I want it to due is trip my 180W ZW in a short situation?

I would use it as is "out of the box" If you find it is tripping because of normal loads, then raise the trip level.

I like CAPPilot's Sonalert. Thanks for the diagram, Ron.

I am using the 8 amp PSX setting with a Lionel PH-180 (10 amp). I used switches similar to what cjack posted for my manual resets. I also used the sonalert CapPilot posted, but it is now a Digi-Key #458-1087-ND (Sonalert MSR320R), as I believe the MSR320 has been discontinued. Tony's Train Exchange had a screw terminal kit for the PSX-AC (around $6 I think it was?) if you want to add them.
