The most evident approach is just to use initialise array function on the first iteration of your loop, but... There are really many loops in your vi, so may be its better to use zeros as defaul values for your array indicaters and before each run apply a "Reset to Defaults" method. But for this you must make some kind of a higher level vi which will perform "reset to defaults" method on your vi as this method doesn't work in run-time (or may be I'm wrong?)...
