RM2 WD bypassed for now

Control room

RM2 SWWD has been bypassed temporarily until we offload some of it since we're near the end of the ADC range for one of the channels.

The ADC reaching the end of its range isn't what actually caused the trips though . The HAM1 ISI SW watchdog tripped after being triggered by RM2's LP SWWD. It looks like the LOCK filter bank integrators had started raking up counts, eventually causing large oscillations in the suspension that surpassed the LP SWWD threshold. The integrators for RM1, RM2, and PM1 all started building up at the same time, but for whatever reason the build ups on RM2 were much larger.

Jim says that he doesn't care for the HAM1 ISI whether any of the little tip tilts on there trip, so we're bypassing RM2 for now since its the closest to tripping.
