Its likely that the CW-80 and PS-1 dont work well together. PS-1 needs to be at less tan 8-10 volts on the track to leave reset position. You might try lowering the throttle to shut off and follow with slowly raing the throttle to about the 8 volt position. It might start movibg foward and may wok normally with the direction button.
Early PS-1s can be a bit quirky. As an example running the PS-1 Empire state express with the variable channel on the DCS set you are not able to get it to leave reset unless you lowere the source voltage to 0 and then raise it slowly to get the engine to move. After that it works fine with the DCS handheld.
