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. https://dccspecialties.wpengine.com/wp-content/uploads/2023/09/PSXX-Manual-Rev-C-Rev-G.pdf I believe that these are set up with the

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?
Karst and Bob Thank you for your feedback on my question. First, Bob could you share what brand circuit breakers you are using and how you have them setup (jumpers, CV settings, etc.)? ?We have

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

By the way, that it is *IS* possible to get a correct "breaker-operation" is proven by our YD7432 reverse loop controller ?

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?
Ok, Thanks for the explanation Bob.? So it *IS* symptom curing ( minimizing the effect of human error ?) Am I right, that the sole supply to that breaker is the Track-Out power from the booster

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

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?
Well... first I think one should solve the cause, not the symptom. Obviously the cause is that that ominous circuitbreaker does not come after it's specs... ;) Almost... the 5033 will detect

Re: Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?
Hmmmmmm, I have never needed to vary this setting, but, I think the issues could be:- Killing the item that caused the short - But it's already faulty so why worry. Stressing the semiconductors

Increasing the DR5033 Short Circuit Delay to 300ms - what problems could happen ?
Hi I am wondering if anyone has any experience with increasing the short circuit delay on the DR5033 from 96ms (default) to 300ms or more ? This is LocoNet CV 13 that is being increased on the

Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?
It could be you're experiencing 'switch bounce'; no switches close in one clean motion, but instead bounce open & closed multiple times in a multiple msec or tens of msec interval before staying

Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?
Stuart The trip time on the EB1 is controlled by CV130.? I have set CV130=1, which should give a 16 ms trip time.? In theory CV130 =1 when shipped from NCE - I purposely set it to make sure it was

Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?
I use a couple of NCE EB1 with my Z21 in the accessory bus and only changed the current trip to 2.5A to ensure the EB1 trips before the Z21 or the booster. I wonder if you have reduced the current

Re: NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?
Jay, I have not used this combination before, but I have a couple of thoughts. What have you set the trip time on the NCE EB1 circuit breaker? I think the minimum setting is ~10ms. Can you try the

NCE EB1 Circuit Breaker - is anyone using these with a YD7001 and DR5033 boosters ?
Hi My club, York Railway Modellers, purchased several NCE EB1 circuit breakers and we cannot get them working with our YD7001s and the DR5033 boosters without increasing the circuit breaker trip time

Re: Resistor for block detection, best size?
You will see that the block detection (i.e. when current is drawn) appears slightly before the Railcom ID is displayed. This is because it is faster being almost the instant a loco enter the block.
By Iain Morrison · #4827 ·
Re: Resistor for block detection, best size?
So let me ask a dumb question, as I’ve only set up sample blocks with DR5088RC and have seen the RC ids show up in my blocks but don’t actually detect any current. The question: Why do I care

Re: Programmer Busy reading CVs with Ops mode over Railcom with YD9401
I tried 2, 3 and 4. With 4 I get some (fewer) Programmer busy messages. With 2 and 3, I don't get Programmer busy, but I do see pauses., fewer with 2 than 3. It seems that 3 is the best setting for
