intermittent chuff sound on Paragon2
Posted by eds-trains on Thursday, January 3, 2013 5:03 AM

My J1E 464 Broadway Limited Paragon2, with a QSI sound, shorted out when the pilot wheels went off the track. When I restarted the loco the chuff sound did not work. All other sounds worked fine. I have done a factory reset changing cv49=128, cv50=255 & cv56=113. At first there was no change so I tried again. Now the chuff sound is intermittent. Sometimes it works sometimes it doesn't. Everything else works good. 

Any Thoughts?

Ed.

 I thought the Paragon 2 decoders have a reset button? I believe those CV changes are for a QSI decoder. If all else is working I would be looking at the plug to the tender and some BLI locos such as my M1a and others have a chuff sensor. It is a reed switch that picks up a magnet mounted into the flywheel. On my M1a the sensor came loose and needed to be snapped back in.

You need to download the technical reference manual for the Paragon2 decoders from Broadway Limited's web site.  The CVs you reset are for a QSI decoder, which is not the same.

My mikado does this but it' s usually due to not clean track spots or not clean contacts or wheels. I clean the drivers by running atop alcohol paper towel, the other wheels and tender axle pickup leaves with Dremel polishing. My older BLI mountain does not do this.

I reset to factory per booklet cv guidance. Maybe set cv8 to 8 if I recall.
Don't know if a button reset affects differently. When I reset and wheels are clean it does ok for awhile.

Just from my perspective.

i'm sorry. I thought my post stipulated a QSI sound decoder.

The confusion is, you said Paragon2 in your title.  Paragon2 locomotives use a proprietary decoder that is not from QSI.

Broadway Limited used QSI sound decoders in the original Paragon products, but Paragon2 does not use QSI unless you have modified it.

Ed,

QSI is what BLI used in their earlier Paragon locomotives.  As Chuck indicated, Paragon2 locomotives use BLI's newer proprietary sound system; the same used in their Blueline locomotives.  It uses a different reset CV.

I don't have the documentation in front of me but you could try CV8 = 8 to reset your decoder, which is what most decoders reset at.

Sorry Ed.

 The title and post said Paragon 2 and QSI. These are 2 different animals. Did your J1e come with a magic wand? My BLI with QSI I1sa has a jumper plug for a hard reset. Did you try to reset on the main? If it is a QSI decoder it will say RESET after a power interruption after doing either the 3 CVs or the reset switch.

  You say everything else works but I would still look to the plug and maybe download a parts drawing and see if it does have a chuff sensor. I know BLI had some problems with defective chuff sensors awhile back.

Thanks to all. I reset the jumper plug and all works fine now.
