Gate continues trying to open

[SamA]

Hello All--

New faac 402 with 455 d control board:  Gate continues trying to open more after stopping and reaching approximately 90 degrees.
For about 20 seconds it will make loud humming sound, like it is trying to open.  After the 20 seconds it will go into the pause mode and subsequently close. Why is the arm doing this?  The 455 d manual does not seem to address.  Appreciate any assistance.

Thank you,
Kevin

Good Morning,

It sounds like the board hasn't learnt its limits or lost its memory and is over running. If you go into the first level of parameters and select time learning this will relearn the limits.
