Tue 24/Jan/06 9:45 GG RUN.
9:50 GG Dummy staves ON. Dummy staves detached where no ARALDIT had been deposed. Dummy staves at 10V->2.8A, system in RECOVERING. ARALDIT deposed "everywhere".
14:35 GG Weight 27 kg. RUN.
14:47 GG Dummy staves ON. Weight 20.7 kg.
15:38 GG Weight 20.4 kg stable for 20'. Opened loop 2. Weight 19.6 kg.

19:07 GG RECOVERING.
Wed 25/Jan/06 15:10 GG STOP. Weight 27.2 kg. Chiller parameters modifications. b00 from 0 to 1 (display the temperature coming from the evaporator and not the goint to one); r06 from 0 to 1 (setpoint is the temperature coming form the evaporator); r02 from 1 to 5 (chiller ON between the temperature [setpoint, setpoint+r02], currently is [5, 10]. No more alarm A01.
Thu 26/Jan/06 15:55 GG Difference of ~ 1C between the temperature of the water out of t chiller end the water entering in the condenser. Chiller from 10C to 5C in ~ 2'; from 5C to 10C in ~ 14' (cooling dependant).
18:20 GG Liquid pressure from 2.725 to 2.700 b.
18:41 GG Liquid stable at 12.2 kg since ~ 18:15
