Had this issue, and saw a couple of previous posts about the same issue, and no real answer. After messing with it I figgured it out. The issue is that when the lock is initiated, it attempts to lock, but in the wrong direction, sensing an obstruction, and then throws an error. There seems to be no way to reverse the direction. No code, no mechanical change to the hardware etc.
SOLUTION: What caused this issue for me, was I initiated the lock BEFORE actually installing it on the door. When you 1st power it up, it does a test. It says "press the Yale Logo" and then it attempts to lock, and if it fails, it will automatically try the other direction. This is critical, as it only does this once on initial startup. In my case, I powered it up before install to test it, so on it's 1st attempt, it encountered no resistance (going the wrong way, as it was not on a door), so it assumed it was correctly configured for my door. Thereafter, it always goes that direction. I had to factory reset the lock, re-install it, and power it up. Sure enough, it's 1st attempt was again the wrong direction, but then, instead of thowing the error, it switched to the other direction, and it worked correctly.
Hope this helps.
