HI all,

Wondering if anyone can tell me what a typical internal temperature for the CS3 might be?
I had an issue the other day where my layout became unresponsive to any input from the control knobs on the CS3. The trains kept going at the last set speed, but I no longer had any control over them. Funnily enough, signals and turnouts were able to be operated using the CS3.

I suspected a short of some kind messing up the control signal, but after a lot of examination couldn't find a cause.
Tried resets, restarts, checked for the latest software update, all to no avail.
Seemed to go away after a long period of shutdown, and now I am unable to replicate the problem.

Im wondering if it might have been an overheat issue with the CS3?
Can other CS3 owners out there tell me what a typical operating internal temperature is for their CS3? I cant find anything in the manuals regards specifications that helps.
I have tried connecting back to the layout, and also with nothing plugged into he CS3 at all, and the internal temp seems stable at about 42 degrees.
Ambient temp in the room is 27degrees.

I didn't check the temp at the time of the problem, nor do I recall what it used to be prior this event.
I would like to know what the normal range of temps should be so I can assure myself there is nothing wrong with the CS3.

Any help from other operators out there would be very much appreciated.

cheers,
hugh

Has any of our other CS3 users experienced this issue?

Some software glitches of the CS3 since the introduction have been fixed, and I suspect this is a software thingy too - could the operating temperature measurement logic be an issue for shutting down control of loks?

Don't have a CS3 myself, so I hope members who have a CS3 can help a bit here...

Did you try unplugging and replugging the unit to see whether the problem went away?

This temperature is in line with my observations.

While a high temperature might be expected by certain design, the reporting and "RED" status imply an issue (or so I thought)
However, Marklin support were non-committal on the subject.

Your symptom does sound familiar, at least from early last year. I would ensure that you have the latest code as there have been a number of updates to the GFP.

At varying stages (firmware versions) it has been obvious that that detection (mfX and mfx+) logic was one reason for hang causing other functions to appear not to work.
I recall an event early last year where I was chasing this down (reproducing and bisecting - with resultant soft and hard reboots) where the "warm smell" became evident and had me looking at the temperature as either a cause or bi-product

My CS3 gets very little use these days and I do not know if these issues have been addressed or whether it may be that I have learnt not to push the boundaries that lead to them manifesting themselves.

Hi Hugh

For sure a 42°C internal / board temperature is normal and it is probably not the cause of your problem.
Besides you indicate that digital current is still provided only the controls become non-responsive. The first thing a thermal protection does is to switch off power output
Even though you have the last software version I would suggest to do an online update as this may bring some corrections. Otherwise you may be dealing with a h/w problem.
Cheers
