Good Evening,

For the life of me I can't find the current and voltage settings on the CS3?

Are there user defined fields that I can change so that I can have a lower voltage and current setting?

What I'm trying to do is shorten the time it takes to trip the CS3 into overload (short) timeframe.

Thank you. Michel

I think I found my answer from another post....

The ECoS comes with an adjustable power supply and you can set the threshold for the internal booster somewhere in the software.

My "ECoS" 60212 is capable of 4 A output current, but I set the threshold to 2 A for increased safety.
Nice feature the CS2/CS3 don't have.

Hello Michel,

if I understand your question correctly, you want to know where at a CS 3 you can alter the current from 3 A to 5 A?

I asked this question the Maerklin Service and their answer was unfortunately not distinctive. Interpretive it correctly you may alter the current by selecting the different “Netzteil” 60061 for 3 A and 60101 for 5 A. Please compare and see it at page 33 in the CS 3 manual, section “GFP 3 settings”.

Regards

Wolfgang

On the CS 60212 I can set the current limit to 4 A or to 2 A or to 2.4 A - or to several other values.
I use 2 A to reduce the risk of damages in the case of a short circuit.

The CS 60212 is AFAIK the only Märklin controller that supports the MM protocol with 28 speed steps.
Sometimes such simple configuration options make the users happy.

It's the Märklin way to set the current limit implicitly by configuring the power supply. And the 50 VA power supply for the US is probably still missing in the list - at least it is missing in the CS2.

All this talk about maximum current values may have some merit in dubious load situations, however a short is a short and the question was

The time to shutdown for a short is purely based on design of the power supply.

If you have poor wiring or dirty wheels , and resistance comes into play such that it is not a true short then, sure, the various settings for current limit might come into play. But , again, the delay before the power supply depends on the design (which may be a software timer)

Also , If anyone has listened to a the "sizzling" around a derailment they will know that the power supply cuts out and retries a couple of time (just in case the short is transient) before finally throwing in the towel. The number of times a retry is attempted is not the same as the the current rating of the PS


Rather than dwelling on 2nd guessing the knowledgeable designers of the power supplies, any layout modeler would be well advised to focus on the quality of their wiring and power distribution, so that a short is quickly and succinctly detected as a short.
Poor wiring joins or wires incapable of transmitting power without significant resistance (too thin) will hide the short from a power supply even if its sensitivity was wound right down.
