Re: Loco Shuts Down

Marcus Ammann

Hi Mike

The "Shutdown" feature is described on Page 12 of the Diesel Manual at:

Because I use "Sound of Power" - Heavy Load on my QSI equipped loco
especially the NSW AD60 Garratts (Australian) that is pressing F9 when
running, some operators inadvertently press F9 with the loco stationary
(idle) and no the loco goes into the process of "shutting down" and no
amount of pushing buttons gets the loco going again, except pressing F6

For me this means I have to "recover" their loco during an operating session
because of a feature I never use. So I remap the F9 idle to "None" and my
problem is solved.

I re-read your initial post on this subject, 3 idling locos and when you
accelerate away with your GP30, it shutsdown.

Do the headlight go off, if so loss of power possibly dirty wheels/track or
a severe loss of voltage due to an excessive voltage drop in your wiring
from the Power Panel.

Do other sound locos shutdown at this same location?

This issue is not because of QSI's Shutdown feature accessed by F9
(default), so the explanation above is just for your information.

Now for Decoder Pro, make room for your Power Cab at your computer. Heck it
does not take up much space and the Track can be on a shelf etc and the
Handpiece can hang "somewhere". What are you trying to find excuses for not
getting connected? All you need is the NCE USB Interface and Power Cab
software 1.28c. Download Java and Decoder Pro onto your Desktop and you're
good to go.

Once running Decoder Pro, you'll wonder what the fuss was about. See my page
for getting your Power Cab/USB connected to Decoder Pro at:

For lots of other DCC stuff, see:

For myself I have a Laptop on my Work Bench in my Train Room connected to my
NCE Power Pro Box via a USB to Serial Adaptor and connected to the Internet
via a Wireless Access Point and Modem in another room next to the Desktop
for my Kids and the Boss.

I take my Laptop along with my Power Cab/USB Interface to other layouts and
program/reset locos and have become know as the DCC Doctor with my Silver
Aluminium Case.

Suitable second hand Laptop and now new ones (Netbooks etc), are really
cheap these days, no need to feel like you are missing out on the best
programming utility around. I would not be without Decoder Pro and my
Aluminium Suitcase.

Hope this helps

Hi Marcus,

I do not understand what you mean by the "shutdown feature" Is it described
in the QSI manual?

Decoder pro, well that means I have to haul a computer out to the layout and
figure out how to hook it up. Maybe when I get a laptop. Then I do not have
a network connection out there. Maybe wireless, then there is yet another
computer and related stuff to maintain.

Maybe bring the programming track and the Power Cab into the house, but
there is no room for it in the computer room.

Ah well.

Hi Mike

All QSI decoders are reset by programming:

CV 49 to 128
CV 50 to 255
CV 56 to 113.

Then remap your functions and get rid of the Shutdown feature.

Done more easily with Decoder Pro, than with the Decoder Manual. If you have
not already got Decoder Pro, it is time to, especially with programming
sound decoders. For Decoder, see:

Decoder Number is 113, version 6 (QSI)

I have tried turning off the DC capability using CV 29 with a decimal value
of 34, both on the programming track and on the main. Per the QSI manual
version 3.

Behavior is the same.

I tried the F6 as you suggested (6 on the keypad) 6 showed up as the last
digit on the readout, then went back to a dash.

It appeared to make a difference, but when I moved the loco from the
programming track to the main, the same shut down behavior was exhibited.

I could not find in the Power Cab manual about the decoder reset feature.

Mike,Not likely to be an inside issue. Try pressing F6 2 times about 1
second apart to unlock the decoder from the sound only/idle mode. Use the
PowerCab programming track features to read the codes to get mfg ID and
model # of the decoder. Need to know what decoder is inside, but you might
also try the decoder reset feature in the Power Cab. OR... Call Walthers and
talk to their rep.

I have a Proto 2000 locomotive, GP30, Santa Fe, road number 3132, Part

I am using a Power Cab to power the layout, and have it set to read
With no track connected = 0.04 amps
With track connected and 3 locos not selected current = 0.18 amps
3132 selected, at idle, and sound working current = 0.28 amps
add headlight on current = 0.28 - 0.29 amps
add horn blowing current = 0.34 - 0.36 amps.
headlight on and bell ringing = 0.29 amps
headlight on, bell ringing, and horn blowing current = 0.36 amps.

Thought you might find those numbers useful for reference. Now to the
When I try to move the loco forward or reverse, the sound speeds up, the
headlight gets brighter, then the entire loco shuts down. I have to remove
it from the track, wait a few seconds, then place it back on the track to
get its attention again.
The track never loses power.

It seems to e that the problem in internal to the loco. How do I get the
loco apart? Anything I should look for other than a black decoder?
Does this loco have a separate motor decoder and sound decoder?
