Lets say the thermal overload trips when set with the bypassed direction engaged. The motor then slows down to the point where the centrifugal switch engages. This then puts one half of the run winding in series with the start winding. I'm not sure what would happen but I suspect with a light load it would keep cycling on an off and a heavy load would never get up to speed and eventually smoke the motor.
To the original poster I do believe there is a way to wire KM2 & KM3 to work with this motor. I suspect it will require small changes to the wiring of KM1 also. What I don't know for sure is what F-R is in the original diagram. The actual connections to contactors Km1, Km2 & Km3 are also a bit of a mystery so I would not be able to tell you which terminals to use. For these two reasons I am a bit reluctant to post any updated diagrams without knowing for sure what that stuff is. If you weren't 2700 miles away i would be in a better position to help.
