I've unmonitored the SUSETMX/YPI SWITCH channels at Vicky's request
I don't think we need PI damping most of the time now as TCS has settled, so I am minimalizing the SUS_PI guardian code to only start ESD damping if necessary. The following changes have been made to SUS_PI guardian; if all is good we can remove SUS_PI from ISC_LOCK soon.
The guardian reload kicked us out of "OBSERVING", because SUS_PI guardian was not "OK" for about 60ms as it reloaded, see trends.
Camilla, Vicky. We've increased the PI damping thresholds to: mode24 @ RMSMON = 10, mode31 @ RMSMON = 12.
