It looks like the soft start manual has some errors.
T10 should be 0V.
T9 will be whatever OB is, and is adjustable with the trim pot.
If you believe there is an error, you can post the IA, OA, IB, OB, KregA, and KregB voltages here and we can assist you. Beyond that, the terminal strip voltages are a small sampling of these voltages.
