Re: DCC Specialties PSX-AR

William Warren
 

The power for the AR is coming from the NCE Power Pro Booster directly. The power for the mainline Peco #6 is coming from a DCC Specialties circuit breaker.


Re: DCC Specialties PSX-AR

William, are you feeding the input of the auto reverser from a circuit breaker?
I had a similar problem with that type of connection. Try feeding the auto reverser directly from your DCC power supply.

DCC Specialties PSX-AR

I have hooked this AR in my wye, but I am still having problems. I have insulated both legs of the wye coming out of the wye and leading into (2) Peco #6 Electrofrog turnout back to the main line. on one side the transition is seamless. On the other side when the lead locomotive leaves the leg of the wye and moves across the insulated rail joiners into the #6 turnout the short buzzer on the AR goes off and there is a momentary pause in the consist as the locomotives leave the wye leg and enter the mainline. It only happens one that one side not the other. I am stumped to trouble shoot to solve the problem. 

Any and all help will be appreciated.

Tom/all,

  There is one approach to wiring that works - and all the rest don't
work as well.  It goes like this:

  What you wire today - you test today (or first thing tomorrow morning).

  Seems simple enough - but the important part of it is that you end up
with an "ever growing - Working - railroad".
  Although testing with a meter can work the best method is to actually
run a train (loco) over the newly wired track that you just wired.  For
example testing with a meter probably would have shown your EB1
to be "OK" but running a loco across that joint would have shown
the flipped wires right away.  Yes, there are ways to test with a meter
that find everything ... but my experience is that running a loco is
quicker and more positive.  Plus you get to run trains!

  One of the worst practices is to wire for days, weeks, or months ... and
then test.

  Sometimes scenery work can cause a short.  Usually only temporary
but not always.  Scenery is often far after the track wiring.
                                                                                                      - Jim

P.S. My experience is that the EB1 breakers are fine (work well) ... until
       you start to use sound locos or lighted passenger trains.  I use
       only the PSX breakers for this reason.

Re: Switch 8 MK2 and Button Board

Tom Grassi
 

Alan,

thanks for the reply.

Yes I know about the extra terminals on the newer version of the Switch 8 MK2

I have had 3 Switch 8 MK2 already and not one of them worked with the button board.  As I said in my first posting the old style switch 8 mk2 works great with button board.

I have been working with Larry the DCCguy  and he has his switch 8 mk2 working fine with just using DC power  but he did say he received a bad batch of Switch 8 MK2 that did not not work.

I am sending my Switch 8 MK2 and Button Board to NCE with the wire I used and button see if they can get it to work.

I have one more Switch 8 MK2 I will place on the layout to be able to switch the tortoise motors using my power cab.   I have the NCE USB board on order so I can connect with my Laptop soon.

I like to push buttons they are nearby and makes it easier than going thru the levels on the power cab I know once the assy is select I can double click on it to toggle the switch.  but when you have many switches the panel board is easier
With that said I need the Switch 8 MK2 new version to work with the ButtonBoard

Thanks
Tom

Hi Tom,

I noticed the extra set of contacts on the Switch8-MkII.  I had initially wired it up wrong when using the Button Board.  Once I realized my mistake, I was fine.  Here is what I wrote about it on my website:

Switch 8 MK2 and Button Board

Tom Grassi
 

Hello All,

Been having a problem setting up an NCE Switch 8 MK2 using a Button Board.

I have two SWITCH 8 MK2  both have a button board connected.  One works great push the button the track switches use the power cab and the track switches.  That Switch 8 MK2 happens to be an older version than my second one.
Both were purchased with the last six months.  The new version has an additional terminal with three screws for a relay board .  My original Switch 8 MK2 does not have this. NCE support claims that there is no software difference between the two I found that hard to believe since there is a physical difference in the board.

Both boards are wired the same and are connected to the same buss line 

I have 4 buss lines on my layout each are a district which I use NCE EB1 

Switches are controlled by Tortoise machines are and located in all 4 districts.

I watched several videos on how to hook this up and they all have different ways.  

I am using DCC only on them and not sure why the one works and the other does not work.

Any one out there have any suggestions.

Thank you

Tom

Re: NCE DCC EB1 Circuit Breakers

Hello
I was able to get my EB1's setup and working.   The track isolation took a little work and I had to replace some pieces of track the Dremel tools cut the rails no problem but on small pieces of track it tore it off the ties.

Since I had to replace the track I used isolated rail joiners.  couple of the larger sections of track worked well.

The EB1 that was shorting or open was a wiring problem.  I had to flip the two wires on the buss line at the EB1 connection polarity was wrong.

Thanks again for all the responses.

LiftGate Reverse Section #file-notice

PTJ27
 

Hi,

I hate to ask another reverse loop question, but before I lay all the track and do the wiring, I want to verify that I have it right. A schematic of my proposed layout has been uploaded to the files section as “20210323 Rehab.pdf”.  If the experts could take a look and comment, I would very much appreciate it.

Some background: The original layout was a folded dog-bone with the reverse section between the upper and lower wyes. Command station is a DB150 and auto-reverse via an AR-1. A recent addition, the section on the right (Engine Terminal & Staging deck), is connected to Loconet, but separately powered via a DCS51 configured as a booster and double gapped at entrance and exit.

I intend to replace the AR-1 with a PSX-ARSC and add another PSX-ARSC and configure the CVs to set one as primary and the other as secondary. My intent is to set the reverse section as the track from the upper wye through the liftgate through the double crossover, and including the leg down to the lower level.

While I haven’t scoped out the detail for the industrial areas, I anticipate that they will all be one-way in.

I appreciate any comments.

Thanks,

Paul Jara


Re: NCE DCC EB1 Circuit Breakers

Don Vollrath
 

Tom, there is a difference between a “short “ or short circuit that causes a circuit breaker to trip and a loco to stop, and an “open” that simply causes a loco to stop. Be sure to use the proper words.  In your case It sounds like you have an open connection or broken wire, etc. use a voltmeter to help find where and why you loose DCC track voltage. Shorts can be caused by miswiring of the left and right rails as a loco crosses an isolated boundary between sections. Look for voltage across the same rail isolating gaps. It should be minimal. If there is significant voltage there you have a voltage Mis-match in your wiring.

From: trgrassijr@...
Date: Fri, 26 Mar 2021 09:57:44 CDT 

Hello All 
New to this Group 
Hope all are safe and well.

I have a small layout and runs 3 trains at the same time.  Have 14 switches
Use Atlas code 83 track on my layout.
I use NCE Power Cab to control my trains.
sometimes a train would derail at a switch and that would short circuit my entire layout. 
So I decided to setup Districts on my layout I have three districts now and forth one in planned.

My layout was all tied together by switches as cross overs.  also have a double cross over on district 2 and 3  

So I had to isolate the track on district 1 from district 2 and 3   in doing that I ran into a few minor issues.  On District 1 I found I now had a dead section of track which worked fine before I isolated the track.
After many trouble shooting step I found I had a bad feeder wire on a piece of track before the dead section.  I think it was shorting in out somehow.  Replacing the wires will be done soon currently I disconnected them from my buss.

My buss is a 14 AWG stranded pair of speaker wire  

Now with the three districts I have three separate buss lines 

My problem now is on District 2 on a section of the track it short circuits and the train stops 

I have feeders before the section and after the section it is a dead spot not sure what to check

I tried to put my layout here but it would not let me.

Any one have any ideas what to check

Thanks

Tom

DB210 with DCC++ EX Command Station 
From: Blair
Date: Fri, 26 Mar 2021 14:40:36 CDT 

A friend recently purchased a Digitrax DB210 as someone told him he'd need one for his layout.

He's trying to figure out how to connect it to his DCC++EX base station.

Can he simply use the signals from his rails to feed the Loconet RailSync wires to the booster (he wouldn't need more than 5A, so the DCC++ rail outputs are otherwise unused)?  What about the 'ground' reference booster input?  I suspect that's not necessary as long as he's running just the one booster for the whole layout - unless he uses a PM42, obviously, or other Digitrax device that needs the reference.  Comments?
Blair

Re: Remote control of boosters, etc.

Peter Ely
 

 

Another option I’ve used wiring some clubs are delay timers on the AC side. More expensive than Robin’s and the other solutions but perhaps simpler depending on your skills. Of course these are on the more dangerous 120VAC side. ~$15  each . I’ve used items like these for individual boosters, or full nodes, depending on requirements and current capacity.

 

These are transparent to the user and basically when the AC is turned on, these wait a set amount of time before passing the AC through to the device(s).

 

Examples

Re: Remote control of boosters, etc.

The Club layout has a master timer on the layout power supply. All layout electronics, light power converters, Arduinos, etc. on same circuit.
Push button, cycles through 2,3,8,12 hour timeouts.
Layout JMRI PC is on UPS, also on same timer circuit. When powering off, UPS lets computer do controlled power down.
User friendly for club members. Only one timer to turn on. No muss, no fuss.

Re: Remote control of boosters, etc.

Blair,

Sounds like a nice project. I've been using cheap ebay TC12000 12v delay relay boards, with In+ connected to Loconet Pin 1 and In- connected to Loconet Pin 2. The boards have a built-in diode on the input so I just add a 10 uF filter cap after the diode to create DC power for the circuit. Downside is that the board draws about 35 mA Railsync when the relay is energized.

Subject: [w4dccqa] Remote control of boosters, etc.

I've built a small detector circuit which detects Railsync on the Loconet cable and, after a programmable delay, energises a relay. That relay turns on my booster at the far end of the basement. A second such circuit enables my collection of UR91/92 and LNWI wireless interfaces mounted at ceiling level in my train room. So, now nothing powers up until my DCS240 is up and "alive". So far this is working quite well. Why did I do this? I disliked having various items scattered around the room that were powered even when I had no intention of running trains.

Comments?
