Can someone post a manual for the QSI PowerGuard? I checked, there's not one in the sticky thread at the top of this forum. Thanks.

There is a manual attached to Gunrunner Johns post.

Thanks, but that is the manual for the QSI QS-1 DCRU and sound system, not the PowerGuard. I can probably make use of that manual, since people are always asking me to fix their old QSI and Proto-1 engines, but I'm still looking for the instructions for the PowerGuard.
I might have one as I still have 2 and use them. I will look when I get home tomorrow.
Here is an interesting write up on power spikes, and a technical review of the PowerGuard unit.

I have 3 powerguards and 1 powerprogrammer. I have the instruction sheets.
What do you need to know?

That would be much appreciated here as well. Thanks!
This was taken from an archive of a supplier of the PowerGuard.
Page 4 has installation and operation instructions.

Thanks Larry, that's exactly what I needed. Some good information in there that I didn't know about the meaning of the horn and bell indicator lights, among other things.
I wasn't familiar with that archive site. I looked up their archive of the old Scaled Tin Rail site. Unfortunately it didn't seem to include some of the good technical information on QSI and Proto-1 that was on Art's site when he was still around. Still a useful reference; thanks again.
Are you OK with what Larry posted?

I picked up a QSI Power Guard but no instruction manual how do you wire it up or can someone post a manual for it? Thanks
The link to the manual is in my post above.

I don't have a document/PDF to share so I took pictures of each page. This is the original documentation that came with the PowerGaurd and PowerMaster
Sorry about the numerous images but it's the only way that I can post the info. It's different than the link above.

Thanks for the post of the manual. But I have a QSI model ACS-730 PowerGuard it only has 2 wires coming out the back brown and orange. Taking a wild guess that I have one of the transformer leads going into ??? the orange and brown to track that is a wild guess. Can not find anything on line?
After installing TVS on my little attic layout I donated one of my PowerGuards to Dale Manquen(RIP) for an evaluation of it versus a TVS for clamping voltage spikes. Dale's conclusion-- the inexpensive TVS is far more effective as regards arresting spikes.
However he suggested I keep them for other reasons, in my case it is primarily the flashing lights.
OOPS---not rec and black but one brown and one orange conductor from each PG. Orange is connected to white at T-strip which is common on my layouts. Brown to Hot red and black district railpower feeders on T-strip..

I'm sorry - I really haven't paid attention lately to what I photo'd. Now that I look back, sorry that I didn't answer your question.
Orange = '+' terminal on trannie. Brown = '-' terminal on trannie.
I have the manual for those also, Thanks to you making me aware that what I photo'd doesn't cover the 'guard', I'll photo those the next time I dig them out. Thanks.

Many thanks guys. Just happened to pick it up at a train club meet and thought I would put it to use.
