NCE Power Cab & Auto Switch Wiring Diagram
When the NCE Power Cab DCC system is in Program Track Mode [PTM], the NCE 524266 Auto Switch device automatically routes DCC power from the Main Track to an electrically isolated Programming Track.
While the Power Cab is in PTM, the Main Track will be unpowered to prevent accidental programming of locomotives on the the Main Track.
When the Power Cab is in normal operation, both the Main Track and the Program Track will be powered. This allows the Power Cab, or another Pro Cab throttle, to program a locomotive on either track using Program On Main [POM].
