Command scripts were not setting the right value for the correct state epics variable, when turning the HAM-ISI isolation loops ON. This "correct state" is compared to the "current" state for each main filter module (ISO, Damp, FF,...) to determine whether the ISI is in the expected state, and turn the red indicators of the overview screen green accordingly.
This minor bug was corrected. The new HAMISItool script was committed to the Seismic svn, and "svn up" here at Hanford.
Work was covered by WP# 4702 which can now be closed.
