Q: If my layout is experiencing short because of a thrown switch, how can you reset the switch using DCC?
Many Digitrax operators use the PM42 Power Manager, which provides protection to four power sub-districts.
One segment of the PM42 is used to control track switch power, with the balance being used for train power.
When the inevitable happens and a train runs into a thrown switch, resulting in a short, the PM42 shuts down the track power in that segment, while the track switch power is maintained, allowing you to throw the offending switch.
Because the PM42 isolates only the shorted sub-district, the operations of other trains are not interrupted.
