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

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 ? If so, then there probably lies the problem: 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.

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.
