When the gate closes it reopens by 6" - 8"

Any ideas?

There are several reasons why this can happen.
If safety edges are fitted, the edge may be hitting the closing post, if you have an edge and you have tco4 fitted battery may be almost dead, or your edge may be damaged.

If the gate has slowdown on it and it say starts its slow down at say 2 foot away from being fully closed, there may be damage to bearings, track, drive rack or if it runs on a rail there may be damage there,
try increasing the close torque first, check above, if it still fails and there is a rundown distance set , decrease the distance to half and see if that works.
