keyword=HKS Q1 tripped during hysterisis looping
HKS Q1 cannot initialized and tripped during hysteresis.
Tomo and I went down to Hall C and checked communication.
Finally, we found the trip threshold was changed to 650A.
KQ1's operational current is only 407A, but its BI curve was measured
with an intialization upto 875A and thus we had error during the
initialization.
I set the trip level back to 900A. I checked other trip levels and EQ2's
one was too high (1475A). I reduced it to 900A.
