Re: Problems with booster districts - double gaps

dvollrath@...
 

Richard,
1. did it run OK before but now does not? If that is the case, something broke or an isolating rail gap has closed up or there are wires touching something that is not correct.

2. Does the loco hesitation occur when a loco crosses over only certain booster district gaps?

3. when you were checking with the continuity meter, was DCC power On or Off? There are sneak diode paths inside the boosters that can cause a continuity tester to register 'yes' when power is turned Off..

4. What does a voltmeter show when DCC power is On and you put the Vac probes directly across a booster district gap ON THE SAME RAIL? If it does not read close to zero Vac you have one of the booster connections out of phase (polarity). Diagonal placement of an AC voltmeter across the booster district gaps should read >12Vac but not more than 20Vac.

Hi ... we have a fairly large, all Digitrax layout with the following gear: DCS100 (not providing track power), 3 DB150 boosters, 4 BDL168s for occupancy, 6 SE8Cs for signaling, and 24 DS64s to control our Tortoise machines. We use the recommended Direct Home wiring, have double gapped all tracks between booster districts, and have installed a ground reference wire between the DCS100, the 3 DB150s, and the 4 BDL168s. However, when we test rail continuity over the double gaps, we hear a strange beep, beep, beep from our multi-meter. It sounds almost like a busy signal on the telephone. We were expecting no sound at all, proving that the gap exists. We have triple checked the rail gaps, all our bus wires and track feeders and have nothing crossing the gaps. The only wire that connects the districts (other than LocoNet) is the DCC ground reference. We noticed the issue when locos would hesitate at the district boundary and then continue on. Has anyone seen this before? Where should we look further? Thank you

I am beginning a totally new HO layout having abandoned N scale. I need to buy practically everything. So, I am looking for recommendations for:

* Track
* Switches
* Engines
* Rolling stock

The layout will be approximately 6 x 10. I already have a Digitrax DCS 210 with DT500 throttle I can use.

On my small N layout, I never dealt with Y's or loopbacks, so I wondering what wiring considerations I need to be aware of. Looking at Peco switches and wanting to know should I get Insulfrog or Electrofrogs?

Any suggestions/guidance would be appreciated!

Hi,
   Too cheap.  $32 for something that a couple of toggle switches would do offends me.  This is supposed to be just a simple end of track group of sidings.  Also my scheme would still work for DC though my number of DC engines is dwindling.  Can't remember the last time I bought one.

Why not use Frog Juicers as I did and suggested? Then you don’t have to fiddle with toggles and you can still use basic Caboose throws.

Re: Large Gauge Ground Wire in Parallel with Loconet Gound Wires == Groundloop?

Chris Elliott
 

Hi Mark, sorry for the slow response.

So as requested I've taken a few measurements and I'm a little surprised by the results, but it certainly explains a few things. My results are in the redish colour.

You asked
If you have an ohm better, check if there is continuity between the ground terminal and the metal case.
My result, I removed a case screw and stuck the probe into the thread due to all the metal having a black "coating". The measured resistance between the thread and the ground pin on the front connector was 6.8 ohms.

The next step is to measure electrical continuity between the ground terminal and the loconet ground pins 3 and 4.
My result, to my surprise 74Kohms. Yes 74,000 ohms! This was measured between the ground pin on the front connector and the middle conductors of a dummy loconet cable.

Measurements were taken with a Fluke 1587 and the booster was totally disconnected from the layout and power supply.

Regards
Chris Elliott

Ok,

I have no first hand experience with the new systems.  I am not sure what has changed with the new systems.   The documentation of the new system promotes the ground wire as a AC Earth ground connection which makes no sense since it assumes that they have a safety liability situation which they do not.  They are not making the AC power supply which does have a liability situation and cannot be legally be sold unless it addresses that safety issue per UL, ETL or equivalent safety agency requirement.

Anyway, if it is intended as a Earth Ground connection, then it must be connected to the metal chassis.

If you have an ohm better, check if there is continuity between the ground terminal and the metal case.  There should be if supposed to fulfill its safety requirement.

The next step is to measure electrical continuity between the ground terminal and the loconet ground pins 3 and 4.   I know there is on the older Digitrax systems.  I measured it and you know it works because your suing the large ground wire with the older systems.   If the new system BREAKS that continuity, that would explain why the large ground wire does not work and you must relay on the Digitrax Loconet ground for the booster common function.

I have a DCS100 as the command station. In loconet port A I have a UR92 connected and that’s it. In loconet port B I have the loconet cable that runs to the other boosters. There are no other loconet devices connected anywhere. On the DCS100 the “home ground” is connected to the little digitrax installed pigtail. This pigtail is connected to a lug which is held against the rear heat sink.. 

The “home ground” wire runs for approx 14 metres before reaching the first and second boosters, it is a 2.5 millimetre cable (approx awg 13) It does not connect to anything else.
The “home ground” wire connects to the ground terminal on the front of a DB210 and then daisy chains off to the second DB210 and connects the same way.

I had previously wired a friends layout which has a DCS100 and six DB150’s configured as boosters. I had cut the loconet cables as described in Alan Gartners “booster wiring” and it works without issue.

So when I installed the booster loconet cable on my layout, I cut the wires as described on Alan’s website and as I’d done previously. But the DB210’s would not wake up. The LEDs on the front on the DB210 were not correct and trains would not run on the DB210s power districts. The both rails at boundary between power districts are gaped and insulated. Reterminating the booster loconet cable so that all 6 wires are connected corrected the issue.

Re: Large Gauge Ground Wire in Parallel with Loconet Gound Wires == Groundloop?

Mark Gurries
 

Well that explains why the booster ground wire does not work.

With these new products, what I do not know is if this is a manufacturing defect, an intentional design change by Digitrax or a accidental design omission.

One would need to examine more of these new unit to eliminate the manufacturing defect variable.

I would contact Digitrax and ask them about this.

WIRING DIAGRAM FOR ON30 LAYOUT ??

Re: WIRING DIAGRAM FOR ON30 LAYOUT ??

We'll try to help.  Could you turn your caps lock off first?

Please answer these questions:
1. Do you have a track plan?
1a. Does your track loop back on itself?  IOW, will a train be able to go on the same track it was on previously without changing direction?
2. How many operators?
3. How many locomotives in use at one time?
4. Do you plan on any sort of signaling, even crossing signals?

Well, details - how big a layout or more important, how many trains, oops, how many engines do you expect to run at a  time?  Maybe a beginner system ($160?) could handle up to 5 engines, a basic system ($450-500) perhaps 5-10 locos or many double or triple-headed trains then a system with multiple boosters and breaker panels.   NCE is a good system; throttles offer lots of info on their displays.  My club uses it and we run maybe 20+ engines at a time with many boosters with  breaker panels on each.

Re: WIRING DIAGRAM FOR ON30 LAYOUT ??

Bernard,

Get an NCE PowerCab system. Easiest to use. Ideal for a one operator limited sized layout. You can cope with programming of several locos by fiddling with CV settings 'manually' with the PowerCab. No other frills are needed unless you have an reversing track section needing a PSX-AR auto-reverser.

We'll try to help.  Could you turn your caps lock off first?

Please answer these questions:
1. Do you have a track plan?
1a. Does your track loop back on itself?  IOW, will a train be able to go on the same track it was on previously without changing direction?
2. How many operators?
3. How many locomotives in use at one time?
4. Do you plan on any sort of signaling, even crossing signals?

I have been using the NCE Power Cab for some years. Very easy to use. I might run two locos at one time.

I'd suggest you download AnyRail (you can select your track supplier in a menu), enter your baseboard size and play with it to see what fits, what you like and only the talk about equipment.

Re: Large Gauge Ground Wire in Parallel with Loconet Gound Wires == Groundloop?

Chris,

I have one more question. Did you order the “opto" version of the DB210.  Opto and optical isolated version of the DB210?

Well that explains why the booster ground wire does not work.

With these new products, what I do not know is if this is a manufacturing defect, an intentional design change by Digitrax or a accidental design omission.

One would need to examine more of these new unit to eliminate the manufacturing defect variable.

I would contact Digitrax and ask them about this.

Hi Mark, sorry for the slow response.

So as requested I've taken a few measurements and I'm a little surprised by the results, but it certainly explains a few things. My results are in the redish colour.

You asked
If you have an ohm better, check if there is continuity between the ground terminal and the metal case.
My result, I removed a case screw and stuck the probe into the thread due to all the metal having a black "coating". The measured resistance between the thread and the ground pin on the front connector was 6.8 ohms.

The next step is to measure electrical continuity between the ground terminal and the loconet ground pins 3 and 4. 
My result, to my surprise 74Kohms. Yes 74,000 ohms! This was measured between the ground pin on the front connector and the middle conductors of a dummy loconet cable.

Measurements were taken with a Fluke 1587 and the booster was totally disconnected from the layout and power supply.

Chris Elliott

Ok,

I have no first hand experience with the new systems.  I am not sure what has changed with the new systems.   The documentation of the new system promotes the ground wire as a AC Earth ground connection which makes no sense since it assumes that they have a safety liability situation which they do not.  They are not making the AC power supply which does have a liability situation and cannot be legally be sold unless it addresses that safety issue per UL, ETL or equivalent safety agency requirement.

Anyway, if it is intended as a Earth Ground connection, then it must be connected to the metal chassis.

If you have an ohm better, check if there is continuity between the ground terminal and the metal case.  There should be if supposed to fulfill its safety requirement.

The next step is to measure electrical continuity between the ground terminal and the loconet ground pins 3 and 4.   I know there is on the older Digitrax systems.  I measured it and you know it works because your suing the large ground wire with the older systems..   If the new system BREAKS that continuity, that would explain why the large ground wire does not work and you must relay on the Digitrax Loconet ground for the booster common function.

I have a DCS100 as the command station. In loconet port A I have a UR92 connected and that’s it. In loconet port B I have the loconet cable that runs to the other boosters. There are no other loconet devices connected anywhere. On the DCS100 the “home ground” is connected to the little digitrax installed pigtail. This pigtail is connected to a lug which is held against the rear heat sink.. 

The “home ground” wire runs for approx 14 metres before reaching the first and second boosters, it is a 2.5 millimetre cable (approx awg 13) It does not connect to anything else.
The “home ground” wire connects to the ground terminal on the front of a DB210 and then daisy chains off to the second DB210 and connects the same way.

I had previously wired a friends layout which has a DCS100 and six DB150’s configured as boosters. I had cut the loconet cables as described in Alan Gartners “booster wiring” and it works without issue.

So when I installed the booster loconet cable on my layout, I cut the wires as described on Alan’s website and as I’d done previously. But the DB210’s would not wake up. The LEDs on the front on the DB210 were not correct and trains would not run on the DB210s power districts. The both rails at boundary between power districts are gaped and insulated. Reterminating the booster loconet cable so that all 6 wires are connected corrected the issue.

Mark,

The way I read this statement the large gauge wire in parallel to the 
Loconet 'ground'  wires does constitute a 'loop' and could cause a 
reliability problem..

Thus, the recommendation in Allan Gartner's website to cut the Loconet 
'grounds' at the boosters is valid.  Do you agree?

Converting a brass E-60 2-8-0 to DCC

Nick Ostrosky
 

I have a brass Consolidation I'd love to convert for operation on my DCC layout.  It appears the loco picks up right rail from the drivers and left rail from the tender.  I know I'll have to isolate the motor from the frame, but my concern is that the gap between the last driver and first tender wheel pickups may be large enough that if I do have a dead spot somewhere (e.g., in an already-installed turnout that works fine with my F7s) the loco will stall.  Does anyone have experience in this area, and am I being overly cautious/concerned?  Thanks!

Re: Converting a brass E-60 2-8-0 to DCC

Mark Gurries
 

This is where purchasing a Keep Alive with the decoder comes in handy.  It will make up for the consequences of not having all wheel pickup.  The only think you must remember is let the keep alive charge up for a minute of so before you run the locomotive.

Re: Converting a brass E-60 2-8-0 to DCC

Alan Cushing
 

Well, by converting to DCC, you have the chance to put a Keep Alive circuit in there so the loco will be capable of coasting a distance when hitting a dead spot.

Trying to think through what would happen if such a skewed pick-up engine crosses from one power district into another, or into an auto-reverser. It's giving me brain freeze. Any special considerations there?

Is the existing motor suitable for DCC or will you need to remotor? Is there or will there be room for a flywheel? Charles
