There was a brief, outdated section on seismic configuration on the SEI section of the OPS wiki, I've updated this with brief descriptions of each state in the SEI_CONF guardian. The wiki should be consistent with the table on ISI_CONFIG screen. I also removed a bunch of configurations that have been added temporarily during O2. I've also added a button to this page to the ISI_CONFIG screen, it's the big green button top-center of the screen. The button launches a firefox session that goes to : https://cdswiki.ligo-wa.caltech.edu/wiki/SEI . I'll try to keep the guide updated. Hopefully this will reduce confusion for everyone.
