The various DIAGNOSE code might have been included there, since the manual was "model dependant". Stuff like stacker-selection timings, etc. was in the individual hardware manuals, where appropriate. I remmber hunting for that stuff for the 2540 Reader/Punch. Ours was hanging on a 2821 controller at the time. We were trying to do a read-punch-stack function all on the same card; we finally found a better way to handle the situation. On the S/360, selecting which stacker in which to stack cards after they are read or punched is an option with the CCW command code, and is described in the "hardware manual" for that device or control unit rather than in the PoOps.
