In an effort to reduce operator intervention at FIND_IR states:
In the FAST_SEARCH of ALS_COMM, GRD checks if IR power is above a threshold, and therefore "found", before moving any VCO controls. If above the threshold, ALS_COMM advances straight to FINE_TUNE_IR before adjusting any settings. Three times in the last couple of weeks IR power (H1:LSC-TR_X_NORM_INMON) has been just above this threshold for the check, advancing ALS_COMM straight to FINE_TUNE_IR where it has failed with "transmitted power too low", sending ALS_COMM to NO_IR_FOUND where it stays waiting for operator intervention.
I have increased the threshold from 0.1 to 0.15 so it will not move ahead until the power is higher.
TJ changed the ISC_LOCK to let ALS_DIFF repeat it's search for IR last week (
alog 55725), but I don't think it's necessary to do that with ALS_COMM.
It's possible that the frequencies we set the VCO for may need updating. I will look at more successful FIND_IR runs to see what is typical.
