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.
