Have a set of very worn prints but having trouble deciphering what is going on.

5 stop simplex. Upon arrival found car sitting with doors open. Put in car call and doors close and advanced to landing. Doors open then stayed open. Found out of adjustment DOL switch in 6970 operator. Adjusted switch. Doors close after timer elapses or a car call is put in. My issues lies in my hall calls. Input a hall call and car does nothing. If I manually push in XD or XU car takes off and advances to latched hall call landing. I'm not seeing where my hall call relays tie into XD or XU to latch the corresponding relay for up or down call. I must be missing a section of prints or the prints i have are showing it, but it's too faded to see.

Any one an old vintage Otis guy? Thanks in advance.
