+ | ===== The problem ===== | ||
+ | If you are using a 2-Rail system with current detection you must make sure that all surrounding tracks have the same voltage level as the detection section.\\ | ||
+ | This will trigger an event as soon as the first current drawing wheel set touches the isolated detection track.\\ | ||
+ | In all other cases the event will come only after the whole locomotive is on the isolated track. This may significantly disrupt smooth automatic operation by delaying events.\\ | ||
+ | |||
+ | ===== The solution ===== | ||
+ | Use a dummy detection unit for all surrounding tracks:\\ | ||

+ | The sensor event will only occur after the locomotive is completely on the sensor track if the dummy is left out.\\ | ||
