Did anyone figure out what causes this f3 error, I was installing a unit for a client, I had combined two pieces of track from different lots. I did notice there was a difference in the rail thickness at the joint. the Empty unit worked great on the top 5 feet but on the bottom 8 feet, the sound would change and then about half way down i would get a F3 error. It happened with two consecutive units that had no connection – In the end i had three left hand units, the first two gave me the error in the same spot (half way down the lower rail) and the third unit worked like there was nothing wrong… The one thing i did have in the first two was 9ah batteries instead of 7ah. but i have been using 9ah batteries in the last 10 units with no issue… it seemed like it was the track. Unfortunately I did not want to take the extra step and change out the batteries on the third unit to see if that was an issue.
Going to set up a test track in the garage and see if i can figure it out. – My hunch is, it was that particular run of track ???? but i am having a hard time figuring that one out. I have noticed a slight variance in the rail in the past that has caused some other issues such as strong clunk on the connection or one time it was the unit really jerking when the units starts up. I even took a unit that I had installed at home and never had that issue, but did have that same issue on that particular run of rail.. I found i could solve that issue by loosening the 13mm bolts that hold the motor and shift it one way or the other, that seemed to help…
