HELP QSI or QS1 Operators Manual

Do you have the QSI unit in an MTH, Weaver or Atlas engine? MTH used QSI some in their PS-1 engines, so if it is an MTH engine contact MTH and they can give you the instructions or point you to the correct area on their website for the instructions. I got help with a PS-1 steam engine a few years ago from MTH customer support.

If the QSI unit is in a Williams engine you have manual couplers.

I don't have manual anymore but it seems feature 10 enabled  the coupler. However the default setting was coupler off.. (if you did a feature 18 it would turn the coupler "off" )| You may get lucky and be able to turn it on.   Good luck. There also may be a switch on the engine to select rear or front coupler. If you can get it to work you'll need a good battery to have it stick with the engine on power down.

I have a Weaver with QSI in it and it likes the old post war transformers from Lionel. Won't even move with a newer transformer like an MTH Z-1000. 

Maybe a Z-4000 from MTH will work.

 I have a Weaver.  I don't know the model number.  It's a Soo Line SD40-2.  It definitely has electro couplers as I can fire the rear. 

Did you try some of the options with feature10 shown  in the QSI 2 + manual? 

I haven't, but now that you ask, I certainly will!

Yes I have one and I will post it when I get off work tonight. If you're on East coast time you can get it in the morning.

Does it have dual coupler circuit or a switch?  Most QSI and all MTH had a switch to select forward or reverse coupler.  To have independent coupler operation I believe QSI would modify the board to add the second circuit at an extra cost.  I never came across one with the added parts, but I am sure they are out there.  G

Does anyone have a physical or digital copy of the QSI or QS1 operator's manual?  I have figured out quite a bit from the publicly available QS2+ manual, but I have yet to figure out how to operate the front electric coupler.  Any help would be appreciated.

Basil: I have duplicates of early QSI and QS1 paper manuals, in case you still need one of those after using the digital copy that RRADDICT2 posted. (Specify as best you can particulars of engine/board if you need one.)

Where was the digital copy posted?  I haven't seen it yet. 

I have a Weaver 74866.  I'm not sure of the board.  I'll take off the shell tonite and investigate. 

I have a very old QSI 1 manual (eary 90s vintage) that has a light blue cover.  The section on couplers only references the rear one (no mention of a switch to second one up front).   That may be because that manual came with a coil coupler equipped tender that QSI had pre-installed their boards into (an option they offered for a period of time, where the front chapter of the manual covered connecting the engine end of the supplied tether harness to the appropriate motor lugs on various types of Lionel steamers).  I used that board for over a decade and a half, where it migrated across multiple engines,  before it finally started showing its age, being outclassed in terms of its audio by my PSA equipped MTH PS1 engines and ERR equipped Lionels. 

Thanks, Dan!  No need.  I'm pretty much out of the QSI arena.  I'm about to convert my last engine to PS3.
