Massoth 8414002 Uncoupler and Massoth XLS Sound decoder

[frankando12]

Hi
I have a Massoth Auto Uncoupler and as the instructions say I have plugged the three wire attachment Plug into the 7-8 Function port on the XLS decoder and have set CV 124 to 1 as shown in the manual. . The Uncoupler dose not work. In the manual it shows that voltage supplied to Functions 5-8 is set at 5v not enough to work the Uncoupler do I need to increase the voltage and how can I do that, or do I cut the plug off and wire the uncoupler to one of the 1-5 Function outputs . Massoth's instructions are very Vague.

I assume you have BOTH manuals?

Unless they have changed things, you need a separate supply for the uncoupler servo,
BUT
I am out today, so will not have time to get the manuals etc..

All the Massoth Installation Manuals and Configuration Manuals are available in PDF for download at either:
1. USA: AllAboutLGB: A Factory authorized Massoth Electronics USA dealer
2. Germany: Massoth Elektronik GmbH – Passion für Gartenbahnen – With a passion for Garden Railroading

I've ordered the Massoth Auto Uncoupler Units for installation into a Massoth eMotion XLS Sound Decoder so I haven't tried to install any yet myself.

How old is the XLS? From 2016 there is a single 3 pin connector that uses A4 for an uncoupler.



CV124 controls the operation of a Servo on F7 - The Massoth Uncoupler is NOT a servo.

Older versions of the XLS have a connector F7/GND/F8 in the same position shown above. In this case the connector is not suitable as you cannot switch the
centre GND pin.



If you do have an older XLS, use a different output to control the uncoupler.
