thank you for all that info! frankly that sounds pretty cut and dry if it works, and more accessible given my layperson skill level. the panel does have an HMI, Siemens KTP400 Basic, i’m waiting on a download for SmartClient so i can attempt an interface. i’ll update if i see any success
and yes you are right that this is for a chiller and not for an actual centrifuge. the mfg is not someone i want to contact as they’re infamously tough to deal with, nor do i feel they’re competent enough to help given some recent experiences we had with their ‘support’
