The ETMX ESD driver medm screen 'Active light' has been flickering when it is OFF. To fix this issue, I pushed this lower threshold to +/-325 from +/-200.
I also changed this in SYS_DIAG.
While talking about SYS_DIAG, I have made a wiki page for troubleshooting the usermessages that it will bring up. This is a page mainly to help operators find the source of the problem and how to resolve it.
It can be found here: https://lhocds.ligo-wa.caltech.edu/wiki/SYS_DIAG%20Guardian
