I need help in setting CV values for Marklin decoder 60972 to handle Marklin braking module 72441/72442. Right now, the lok will go at the same speed in section 1 and 2 of the braking module and stop abruptly in section 3. Most of my Marklin loks with factory-installed decoders ie., 6090x will slow down in section 1 and 2 and do not reach section 3, which is good. This decoder is a new decoder that I had installed and have not used in several years. I did do a reset. I thought the reset would not affect this slow-down feature. Can't remember whether it handled the slow down module feature before the reset.
Has anyone had this similar problem?
What can I do to correct this? Are there certain CVs I need to reset/readjust from factory settings, and what values should I use. Thanking you in advance,

Thanks Jean. I did what you recommended, set CV27=48. It did not correct the problem. My other Marklin locomotives with factory installed Marklin decoders, as well as locomotives that I installed with LPV3, 60942, and 6090x all behave well/normal with the slow-down module.
So, it may be a defect in this Marklin decoder 60972. I only have 1 of this decoder, so cannot compare with another 60972. So, that is why I am asking if anyone else has had the same issue as I am having with the 60972 decoder. Thanks Jean for your time.

Hi Jean:
I tried using function F4=off or on, and it did not make a difference. The locomotive performed the same. I rarely use the F4 function as I do not do shunting at all.

But the mystery thickens. Since the decoder is in an electric locomotive, and it can be run in both directions, as I was reversing it and running in the reveerse direction, I noticed the slow-down module works in the reverse direction.
So I tested by running it in reverse and now it handles the slow-down module. Very strange. I still think there is a defect in this decoder 60972??
So in the reverse direction, the decoder can handle the slow-down module, but in the forward direction it cannot handle the slow-down module.

Is there a CV I can set to reverse direction of travel of the decoder? Thanks in advance.

Thanks, I set CV29=1 and it reversed the direction and the lights. Works well now in this direction that I usually run it.

Do you think my 60972 is defective when it works in 1 direction only, and not the other direction. Are there additional CVs I need to readjust and set so that it works in both directions? Thanking you in advance.
