well i was servicing a 330 recently, and decided to check the nudging circuit, the door only beeps when the time expires, it will not close at a all. I checked the final timer parameter, and it was set for 40 seconds. Strange, because the above post is from the manual i have, it says it will close the door at low speed and ignore the photo eye. I could have swore i have seen a 330 nudge before, i only have 2 on service, so i will check the other one when i get there. i looked all through the parameters on the job i was on, and nothing to indicate nudging operation. we must be missing something, since the manual indicated it will nudge.
