MC1+MC3 tripping

We have had at least three incidents today where MC1 and MC3 both tripped, we haven't had time to investigate why but this is a new phenomenon.

Kyle and Gerardo were operating the large Genie manlift at BSC3 on Wednesday and I believe also used the overhead crane in that region in order to replace a failed annulus ion pump. Were the trips related to excess motion?
