H1 ISI ITMX ST2 (not ST1 or HEPI) tripped last night at ~9:30 UTC (1179548979, May 23 2017 04:29:21 UTC, May 22 2017 21:29:21 PDT) because Jeff forgot to turn the Reaction Chain damping back on after completing its set of transfer functions (LHO aLOG 36335). 

In order to help non-Jeffs diagnose the issue, Jeff has moved the link to the reaction chain on the QUAD overview screens,
    /opt/rtcds/userapps/release/sus/common/medm/quad/
        SUS_CUST_QUAD_OVERVIEW.adl
        SUS_CUST_QUAD_ITM_OVERVIEW.adl
to the top center (essentially swapping the positions of the never-used hierarchy switch and the reaction chain screen link). I've also added inputs and outputs to the R0 damping loops surround the button to remind people that there's a control system there which occasionally needs attention.

The screens have been committed to the userapps repo.

P.S. This interaction between a full isolated ISI and an undamped chain of the QUAD is not new, it's just been a while since we've regularly taken the full suite of undamped TFs on any QUAD, and I've forgotten that one should put the ISI ST2 in DAMPED. And also I haven't used the matlab automated transfer function suite that does all the settings in so long that I fear it'll do more damage than good. In the limit of infinite IFO time and person power (e.g. between O2 and O3?) we'll resurrect that code.
