To avoid HEPI tripping on L4Cs, I made a simple script to raise the WD value to 99999 on HAM2 HAM3 ETMX ETMY ITMX ITMY. This task can be automated daily by running crontab on a script machine but this needs a SEI approval !
Script is called ResetL4cwd.sh and lives in /ligo/svncommon/SeiSVN/seismic/BSC-ISI/H1/Common/Misc
