MPSRESA- 2 UCB, Oct 26, 2006 Overview Instrument Status Problem Failure Reports Calibration Data Overview
MPSRESA- 3 UCB, Oct 26, 2006 Instrument Status All ESA instruments are fully functional There are no outstanding issues or problems for the ESA. ESA survived the environmental tests and is ready for launch.
MPSRESA- 4 UCB, Oct 26, 2006 Problem Failure Reports 4 PFR’s raised since last review – all are GSE/script/commanding related – i.e. not instrument related. PFR 212 – Radiation source not correctly installed during F3/F4 Probe Thermal Vacuum. Source was installed the wrong way round. ESA HV check out was still possible without the source. Problem was corrected for the F5/F1 Thermal Vacuum test. CLOSED. PFR 213 – No 459 (Electron Burst Rate) Data being received during functional test whilst in Thermal Vacuum. Tracked down to a script error. Script corrected and re-run and verified that 459 was received. CLOSED. PFR 214 – Readback problem with MCP Housekeeping. At nominal setting the MCP HV supply incorrectly read full scale. Traced to a problem in the ITOS database calibration for this value. CLOSED. PFR 220 – Energy tables not written correctly. During the uploading of the tables there were some commanding issues with the probe. The script was re-run from the beginning and problem was corrected. Tables were not reloaded for a full thermal vacuum cycle and no data corruption was seen. CLOSED. All previous ESA PFRs closed.
