I've installed the new changes made at LASTI last week here at LHO on all the BSC chambers. This installation involved model update and watchdogs C code update.

This update could be sum up in 3 main news:

1) T240 simultaneous gain switching

The analog and digital gains of the T240s are now switched simultaneously by clicking on the gain of the X channel.

2) T240s ignored when ST1-ISI isolation is off

Modify the Watch Dog code to ignore the T40s when Stage 1 isolation is off. This avoid the ISI to trip when we restore offsets on HEPI. It also avoid un-necessary trips when the ISI in damping mode.

3) T240 Monitor added

Add a T240 monitor that indicates the instruments have settled after they have been shaken. It's necessary for proper functioning of the SEI guardian and for operators as they both have no reliable means of knowing that the T240s have settled. The monitor will indicate whether the Stage 1 isolation can be turned on.

I've changed the overview MEDM screen to diplay this monitor (see pictures attached). It will do for now, but we can think of something better
