I fixed the problem from LLO alog 8659, ECR E1300715, Bugzilla 398 and LHO WP 4124 where due to an error in the L1 and L2 blocks of the QUAD_MASTER part, the outputs of the DAMP block were plumbed incorrectly.
I svn upped Stuart's corrected QUAD_MASTER.adl and checked that it was being picked up by h1susitmx, h1susitmy, h1susetmx, h1susetmy and h1susquadtst.
I did a make and make install- on all five models.
I restarted all but h1susetmy (which is offline during the chamber move).
I BURT restored all but h1susetmy to 10:00 and reset watchdogs on h1susquadtst and h1susitmy (h1susetmy is offline, h1susitmx isn't connected yet, and h1susetmx had been tripped, presumably due to SEI activity).
