Mount failed to flip based on its reported pier side info

Hello, I'm getting an error when the mount should flip.
I made the settings recommended in the German mount flipping in the help ACP files.
First time the flipping worked flawlessly, without changing anything I then got "Mount failed to flip based on its reported pier side info" the 3 successive nights.
I've no clue about the source of this error.I understand It's probaly related to the AP GTO V2 mount driver. I' using AP900 mount with Ascom V2 telescope driver v5.05.40 last released.
I join the logs, this one is when the flip was OK,20140830@210349flipOK.log other when failed.
Thank you

Are your SURE your mount flips 5 minutes before the meridian going in both directions. AP users can chime in here, but the other APs I have seen seem to flip at the meridian (0HA). I'm not talking about tracking, I am talking about flipping which can only happen as part of a slew. See German Mount Flip Tracking. It is clearly failing to flip when ACP thinks it should be flipping.

I'm afraid I misunderstood the flip settings. My mount flip at the meridian or exactly between 2 arc minute and the meridian, I set 5 mn before the meridian thinking this extra time was a margin of security to avoid a problem, reading again the german mount flipping help file, I understand that this must be the real flipping time in relation to the meridian. I plan to put 1mn or zero and see if that is right.

Put zero and then give it 3 minutes "assure" time. I hope it can TRACK past the meridian a ways. Put a positive value there (the default -5 min is a "I

Mount flipping solved!
Putting the good values helps.
I put zero for the meridian flip and 3mn tracking past the meridian.
Thank you Bob.
