You’ve got the R10 hardwired relay controller there. And EPO if I read that drawing title page right.
Inflight entrapments usually are safe string related. However, the EPO stuff could be problematic too.

Do you have at least the car control page? You know, safety string, 48volt supply, door locks etc.
On a twenty stop, you most likely have comp chain or rope. Swaying ropes from mid rise up/dn traffic can cause the rope to contact the cwt buffer switch momentarily trapping people. I’d also (in the mean time) check all connections big and small on those GE starters. Just a couple of thoughts.

If IDWT doesn’t have what you’re looking for, check member Christy Collett. I think I remember him being a old U.S. guy but also a print collector for anything in the trade.
