Hi Jean,

Märklin's recommendation to use the Telex Coupler mode does not mention changing the 255 dimmer or the 20 (1.00s) as the default Period [0.05s] value.

I haven't found any documentation from Märklin about AUX settings.

Their models do not connect the Telex leash directly to the AUX output. However, the timeout function should be included in the Telex Coupler settings rules, even if it's not used in their own SUSI configuration.

Leaving the button activated on older Märklin models 37679 with this leash will cause continuous operation until you turn it off.

Sometimes I notice a burning smell, and I wonder if the dimmer value should be lower perhaps 40.

However, if selected, the Telex leash would have altered the values in mDT3 or CS3.

Hello Ross,

I'm not exactly sure about the "coupler force", so I never played around with different settings. I have about a dozen locos that are fitted with these Telex uncouplers and I use the same settings for all of them. I guess I follow the saying "if it aint broke, don't fix it"!

Cheers,

Hi Jonas/All,

The noise you get by reducing the power is very small and is done to reduce burn out of the coil.

I am experimenting with the ESU 41002 coupler and in the instructions ESU recommend reducing the power to a value of 21.

Reducing the power on the Märklin E117993 coupler isn't a problem for me but the coupler is bulky and random uncoupling happens to me alot so I'm looking for an alternative option.

Hi Andry/All,

I have only started testing and it all seems to be working well at the moment, time will tell.

You maybe interested in an English translation of the instructions I managed with the help of Google, I added English diagrams of the Lokprogrammer settings.

Hope this helps

On the locomotives I have, that have the E117993, I have dimmed it down to approx 60 (using marklin mLD3/mSD3). This together with a short period and that I have added coupler waltz to most of them.
I have noticed marklin also has the E117993 directly on the decoder aux and as just a regular function, without dimming and periods etc. So if E117993 is on susi, its probably just coincidence etc.

Hello Alan,

Thanks for that lead. Have you purchased and tried this coupler, or know anyone that did? It looks nice and thin (as opposed to the Marklin one).

Cheers,
Andry

Hello Alan,

Yes, I looked at the video. They bang that loco against the freight car pretty hard. I usually try to "sneak up" when coupling. The ESU "dance routine" is very smooth and slow, so I'm wondering if these couplers would work just as well. I guess someone needs to try it out and report. 50 euros is quite expensive, but they might be worth it (i.e., for looks at least) and hopefully for function as well. I'll wait till I read some reviews.

Thanks for pointing these out.

Cheers,
Andry
