REPORT ON THE ACTIVITIES OF THURSDAY 10TH MAY

09:30	Swith on of the Power Converters: RPMBA.UA83.RQT12.L8B1 and RPMBA.UA83.RQT12.L8B2 Beginning of the validation of the sequencer for the procedure of D2. Test on the communication between the PIC and the CRYO signals (CRYO start and CRYO maintain).
10:00	Deconsignation of the PCs of the corrector circuits of Q4 and Q5. CRYO control in the FCR is not available, except a viewer. A voltage tap problem in the circuit RCBYHS4.L8B2 has been detected, the problem will be investigated.
11:30	Waiting for solving the voltage problem. Consignation of the PCs of the circuits: RPHGA.UA83.RQ9.L8B2 RPHGA.UA83.RQ9.L8B1 RPHGA.UA83.RQ10.L8B2 RPHGA.UA83.RQ10.L8B1 in order to allow AT/MEL to install new heaters.
14:00	Consignation of all the circuits of the converters of the Q4 in order to allow Vincent Chareyre to check the problem of the voltage drop in the circuit RCBYHS4.L8B2.
15:00	Vincent Chareyre has fixed the problem. 15:20 start with the PC configuration of the circuit RCBCH5.L8B1.
16:00	16:10 CRYO-OK operation lost. 16:20 CRYO-OK operation found again. PC configuration of the circuit RCBCH5.L8B1 is ongoing.
17:00	Start with the PC configuration of the RCBCV5.L8B2. 17:10 CRYO-maintain forced LOST and PIC removed all the Power permits. Consequently all the PCs tripped off. 17:30 Cryo Operator reported on the situation: the CRYO OK was lost and the CRYO maintain was going to be lost, consequently they forced the CRYO-MAINTAIN as lost.
18 :00	Switch off of the Power Converters: RPMBA.UA83.RQT12.L8B1 and RPMBA.UA83.RQT12.L8B2.
