I just spent another hour turning on ISI ETMX. (see previous elog for ITMX.) This seems to me that most of the turn-on trouble comes from our attempt to turn on loops in an equilibrium position, and afterwards move to the target position. This move then leads to DC saturations in various sensors. Question: Why don't we put in fixed drive offsets - even after the DACkill - that allow us to make the OFF position equal to the locked position. This way the ISI never has to "move", we never have T240 saturations.
