keyword=Cryotarget set to run for LH2, LD2 in rest mode.

Set up all alarms and set the cryo target for initial running:
Loop 1, LD2, in rest mood, fan speed=24 Hz (10%), HP=30 watts.
temperature=22K, Pressure=21 psi.
Loop 2, LH2, in running mode, fan speed=60 Hz (25%), HP=80 watts.
temperature=19K, pressure=31 psi.
15K flow is 17.5 g/s.
This is for using LH2 loop up to 10 uA on 15 cm cell.
To switch to using LD2 loop, need to reduce the fan speed for LH2 from 60Hz (25%) to 24 Hz (10%) (in step of 2-3%) and reduce J-T for loop 2 (LH2) to have 30 watts HP (in step of 1% every 30 second, then increase JT to have more HP to Loop 1 (LD2) and increase fan speed from 24 Hz (10%) slowly to 48 Hz (20%) and reach HP=80 watts.
