During investigation of this "A chain fault" we found the emergency exit crash switch for door 1 (inside the access room) was "crashed". We reset the the switch and everything made up correctly. As a reminder the emergency exit crash switches are for emergency use only, they are not a convenient override of the CANS system

Special Instructions:
lemi should be run and injector energy checked in the spectrometer dump after executing this. Running lemi will lower GSETs in the first four cavities of 0L03 to reduce trip rate in addition to changing GSETs in 0L04. This may require a new injector to NL match.
