Re: YD6940 separating

 

Just snap them with the terminals up, then the push the side edges down.
Re: YD6940 separating

 

I had the opposite problem! :)
The latest YD6940 pairs from DCC Automation came already separated. They are much easier to mount on a board in their pairs.?
Do you have a thin cutting wheel on a Dremel tool?
YD6940 separating

 

Hi,
?
The pack of YD6940s come with the two units attached to each other.? What is the best way to separate them without breaking them?
?
Thanks,

I just bought a brand new Digikeijs DR5000 and I cannot find a link for the software. Does anyone have a link for it, they could post - Thankyou.

Re: What determines the power on position of my turnouts?

 

Don't be like me and forget to update the firmware on the YD8116 before expecting the 'default aspect' to work. This was even required on 3 newly shipped modules.
I kept restarting the app and wondered why the default aspect wasn't shown.
Here's hoping this saves one other person from tearing their hair out wondering why it didn't work.
Re: What determines the power on position of my turnouts?

 

Karst,
I am glad I asked. I would never have found that option to set the default aspect to 16 which is where all of the turnouts show N aspect.
I tried it on one of the YD8116 modules and it worked.?
Thanks.
I've had to install the config software on my laptop as the main layout computer is too far from most of the modules. We do need a way of configuring non-booster modules that are scattered around the layout.
Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?

 

Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?

 

Hi
?
I have an update on this topic.? The simple answer is the NCE EB1s will not work with Digikeijs command stations and boosters, and will most likely not work with the follow-on products from YaMoRC.
?
The simplest answer to why the EB1 will not work is that its short detection time, with a minimum of 16 milliseconds, is to slow to beat the inrush current detection build into the Digikeijs products.? Per Karst here is how the inrush current detection works:
?
The YD7001/YD7403/DR5033 cut the power immediately ( within a single DCC packet's duration ) as soon as a short and/or overcurrent is detected.
They will then retry pulsing the power back on in about a 10ms time interval until the short-delay expires.
?
Because the power is not on for? a steady 16 ms, the EB1 does not detect the short - it is not fast enough to beat the Digikeji equipment.
?
There is another forum member who told me that he to had not been able to get an EB1 working with his DR5033.? He is now using a DCC Specialties PSX circuit breaker.? And as posted by another Digikeijs user in another topic, he is also using the PSX circuit breakers with default settings with no problems.
?
I have also tried a Tam Valley Dual Frog Juicer, set to act as a circuit breaker, with the DR5033.? It works, but you cannot set a retry time (it retries immediately), and it has no support for inrush current that I have been able to find in the Dual Frog Juicer documentation.
?
Hopefully, this will help other forum users to make an informed decision when looking for a circuit breaker to compliment Digikeijs, and probably YaMoRC products.

From the same Update is this:

What determines the power on position of my turnouts?

 

I have a couple of YD8116 switching decoders connected to 22 Tortoise switch machines via YD6940 3 to 2 wire adapters.
At power on nearly all turnouts go to R (reverse) position even though when the layout was powered off they were in the N (normal) position.
I am using the YD7001 to power both YD8116s rather than separate power supplies. The really curious thing is that when I was using separate power supplies I don't recall them doing this!
The turnouts all operate properly when addressed via LocoNet and the feedback modules all correctly report the turnout positions via LocoNet.
?
So my question is this: what determines the power on state of the turnouts when using the YD8116 and YD6940 when the YD8116 gets its power and track signal from the YD7001?

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?

 

It sounds like it's time to drag out an oscilloscope and find out for sure what's happening.
Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?

 

Jay,
I am using PSX and PSXX breakers from DCC Specialties.

I believe that these are set up with the defaults, 2 amp breaker trip setting.
I have the PSXX (newer model that has support for bringing up capacitor charging keep alives) on my main yard track.

I am now wondering if I am getting into a race condition between the DR5033 and the NCE EB1.? By default the EB1 has a short circuit response time (delay time) of 16ms (it can be increased to 512ms).? I did a quick search on the NMRA site and it appears that a DCC packet's duration can be between 95 and 9900 microseconds, less than10 milliseconds.? Is it possible that the DR5033 is detecting the short before the EB1, and then it starts pulsing at 10ms intervals, which the EB1 cannot see as a short with its 16ms detection time? Further, since the DR5033 still sees a short when its circuit delay is reached, it signals a short and cuts the power.? If this is true, why does a setting of 300ms for the DR5033's short circuit delay allow the EB1 to detect the short before the DR5033?
?
I am testing on the workbench as follows:? Track output of DR5033 is set to 3 amps, and is directly attached to the DCC input of the EB1. EB1 is set to short at 2.2 amps. On the track output side of the EB1 I have an on/off toggle switch - turning the toggle to on creates the short.?

  • We have a large 40 foot x 40 foot (12 meter x 12 meter) layout room.?

  • There are 12 town and industrial yards along the main line - some have complex yard configurations that reflect what was in each town in 1955.
  • The layout is powered by 7 DR5033's, and we have a YD7001 command station (it is not used to power the track). Breaking the layout into 7 power districts, was our start point when converting from DC to DCC in late 2019 and early 2020.

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?

 

Am I right, that the sole supply to that breaker is the Track-Out power from the booster ?
Yes, this would be the correct way.
I have three DR5033 and seven breakers. They work fine as long as the breaker trip current is less than that of the booster. This may not be obvious to some... If the booster trips then there is too much of a load on the track between the sum of the breakers. I don't get this but it is possible. There are breakers that do the keep alive charge up cycling, so one would need these if there is a lot of this type of equipment in the block (like a yard or engine facility). Or just dedicate that block to a booster that does this.

Regards,
Bob Gamble

This method is needed to fill-up any buffer capacitors in all kinds of equipment, including loco(sound)decoders. Those capacitors often pose a "short" during initial charging.

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?

 

Karst,
Note: I simply cannot understand why one would install such breakers. The YD and DR power devices really are fast enough to adequately turn off the power in case of a short.

Typically it comes from a desire to break up a layout into smaller power blocks than is strictly necessary based on booster power output. The breaker is less expensive than a booster and some can do auto reverse. The desire for finer granularity is usually driven by operating sessions where you don't want everyone on the power district impacted by one operator who tries to drive through a switch turned against them. But you could make the argument that it would be more elegant to use a booster for all of these smaller blocks, it would just cost you more money and you would have a lot more power supplies unless you cobbled together some sort of power distribution.

Regards,
Bob Gamble

Correct, but not with the full power as described above. Mostly the power-pickups on the trains can take damage from this, since they are usually made of very thin material. I have seen them really glow yellow on certain Lima models...

if the short is cause by the decoder, it is probably already too late. otherwise, shorts usually happen before the power enters the decoder.

Any other risks that anyone can think of ?
not that I can think of.
