Updated to revision 12177.
 

These changes allow the automated switching of the ISI GS13 Gains if desired.  Except for the BS and the HAM6 ISIs, all the ISIs run with High Analog Gain and No Whitening (High Gain State.)  Usually, when the ISIs trip, it is due to higher ground motion.  This is just the time when the GS13s need to be in Low Analog gain to prevent saturation.  For those platforms which nominally operate in the Hi Gain State, the Guardian will be set to SWITCH_GS13_GAIN.  This will alleviate that chore from the operator.  For the BS and HAM6 which do not operate in the Hi Gain State, no switching will occur and they too will require no action from the operator for this reason.

 

Making these changes active requires a restart of the every platform ISI guardian.  I've only done this on HAM5 and I've verified that the intended changes work.

 

The update also turns on/turns off the FF path after isolating/tripping after enabling in the ISI_chamber.py file.  This feature too functions as advertised.

 

I will work to restart and set up the other platforms as the day progresses.
