SUS Guardian issue

This morning after we restarted the ITM and ETM SUS models, the guardians failed when attempting to bring these SUSes back up.  It failed on all 4 QUAD SUS guardians at the same place when requesting to go from SAFE to ALIGNED:

Reloading the GRD didn't work.  In order to get around this we Put the GRD to MANUAL and enabled the output switches by hand, then selected ALIGNING, anmd ALIGNED.

This is now fixed. 

An object called "susobj" is defined early in the guardian, which contains the name of the optic.  In the new state ENABLE_ALL, the optical lever turn-on was mistakenly calling this object "sus" rather than "susobj".  3 extra characters, one click of the Load button, and ITMX went nicely from DAMPED to ALIGNED.

I have loaded the guardian code on ITMY as well, but *not* on the ETMs, since charge measurements are in progress.

UPDATE: ETMX and ETMY guardians were loaded, after charge measurements were complete.
