Neither the 38 or 62 stock that I worked on had any kind of interlock to
cut power if any door was open.
AFAIR the only interlock was (allegedly) with the guard's bell.
There was no interlock, the doors could be opened at any time, any place
without affecting traction current to motors or anything else.
