@Windy City posted:I appreciate the technical discussion but would like to get back to my original and basic questions: theses issues were not addressed in the instruction manual
Do I need a PSX1-AC with the ZW-L? I was going to use it for my PW-ZW. Do you recommend it for both?
Can someone share a schematic of how they place and wire the PSX1-AC and TVS, relative to the transformer?
What version of the PSX1-AC is recommended? Optional LED vs Buzzer?
ADDED: I see you have already answered the questions.
I would use the PSX with both the ZW-L and PW ZW.
I think there is only one version of the PSX-AC. The others, like PSX-1, are for DC. I get these from Charles Ro.
The optional LEDs and buzzer just make it easier to know there is a problem. The PSX will keep trying to reset until the short is cleared, and power will be back on as soon as the short is cleared. Because of this, as a minimum I would add the reset switch shown in Gary's video to J7 pins 2 and 3. This way you have control over when power is again applied to the track.
You have not said what your setup is. Here it is with the TIU in line with track power. No TIU? Disregard the TIU and choke in the diagram.
Here is one way to do it with the TIU in passive mode. Again, no TIU just disregard it and the choke.
