And it is back to root cause number 1: not enough power and infrequent switching.
That results in a build-up of dust, dirt on the contact surfaces which is not burnt away by the switching action and, indeed, by arcing across the contacts. For more interesting literature on this subject see:Įdited by user 10 February 2011 23:19:50(UTC) So, a bit of arcing is indeed beneficial for reliable switching action and that arcing only occurs when sufficient power is applied at.
Märklin has been working on these motors and modifying them ever since they were brought out. The new version 74491 according to Märklin has a new type of switch in them. What I tried to point out in my previous post were the causes of these problems. Once you have these motors built in you don´t want them to fail after only a short period of time. To prevent that, there are a number of things you can do:ġ- Take out or short out the microswitches but only if you switch your turn outs digitally with controlled/limited max. (not possible with the old keyboard and 6021 or Intellibox 1).Ģ- Use the Viessmann 5211 decoder with their DC power module (5215) to power the motors. Or use any decoder, including good old K83 and feed the motors separately with 18-22 Volts DC similar to the Viessmann setup*ģ- If you use analog switching use a separate 16V transformer dedicated to switching your turn outs only and use original purpose built pushbutton switches, Märklin or another good quality brand. Don´t put your elbow on them.Ĥ- Always make sure that the mechanisms are clean and free. Collected dust combined with sticky oil dripping off your loco´s or coaches can be detrimental.
