Something bizarre-o was going on with the PMC and FSS over the weekend. On the striptool, PMC's PZT looks like it was doing a sawtooth pattern for several hours. I opened up the FSS screen, and the FSS SLOWDC had walked itself up to +10. It's not supposed to get that far from 0.
Here are some trends, so you can see what was going on.
10 day trend: This weird behavior began ~Friday evening (FSS_SLOWDC ramps quickly).
1 day trend: You can see the sawtooth pattern in PMC_PZT more clearly here. It's at the same time as the FSS_SLOWDC is ramping rapidly, and the FSS_FAST is saturated.
