Record of events relevant for the TTCS system

Here are recorded date/time and details of the operation on the TTCS system. At the time of writing (March 9th 2012) only the electronics (TTCE-A/TTCE-B) or loop (Primary/Secondary) switch are reported. Routine operations on heaters, needed because of beta angle variation, are reported in TEE ELOG

2013 062:08:05 Mar 3th 2012 TTCS Powered on the COR(auto control) Note: The minimum of PT08 is -52 degree C. And parts of the evaporator drop out of two- phase. (The temp. drops faster, which is due to the locking of the solar array. It is scheduled for 10 hours. Dragon docking )
