Hi Everyone, I've asked this question before in another thread, however, the answer was convincing. The question - on the CS1 there are 2 red knobs which control the loco speeds. When I turn these knobs I don't seem to get a regular response, i.e. sometimes the speed moves up and other times there's nothing and I have to keep turning the knobs before something happens. I comparing the reaction of the knobs to the Mobile station, where i seem to have a regular response, i.e. I turn the knob and the speed indicator moves accordingly. Is this the correct operation of the CS1 or not ?

No, this is not normal,
You should return you CS to your dealer or Märklin.
Mobile Stations had this problem for a long time.
the red knob just would'nt respond to the speed steps.
Märklin sofar have exchanged about 10 Mobile stations for me.

It doesn't seem to make much difference whether they are turned slowly or not. Sometimes they respond other times not. I've returned the CS1 to my dealer and they are going to test it against the one they have in their store. If it's wrong, then it's back to Marklin, again!

David,
I think you missing the point.

It is not normal behaviour.
If you dont believe me, ask Märklin.
They've recognised the fault.

Thanks John & David for your input, however, I'm confused. My thinking is along the line, that the knobs on the MS & CS1 should behave in the same manner, therefore, my CS1 is not behaving correctly. Hopefully Marklin will resolve the problem - it's just another wait for it to go to Germany and back - maybe this time it'll only be 3 months.

Another example is the menu., by searching a particular loco or other digital component such as a cran or digital carriage.
The red button should respond/disrespond in the same manner.
David is correct in saying all depends on your speed level, the speedometer does respond slower or not at every click.
What should happen, if for instance you spin your red knob faster than normal the speedometer should respond to it.
Adrian you've described it as being irratic either responding or not responding to the turning clicks of the red knob.
Having had this problem for almost 2 years and having different reactions from the mobile station, e.g. speedometer or menu data.
I've got 1 mobile station that has a short inside.
I had one that turned itself off.
the only benefit I've got from the old faulty ones (1.2amp) they are all now 1.9 amp.
whereas before I could not run my Roco Swiss Ae 8/14 with 2 motors and a Lenz decoder but was able to run my BLS Re 8/8 with 2 motors.

But also keep in mind that your repaired MS or CS1 will not be faultless. I can not speak for the recent ones. Mine still work ok.
so it could be, the old stock may had the same problem all over again.
I think another guideline is what experiences forum members have had with their digital components and other comments have been made about locos with strange running characteristics.

John.
