FCF PAR Splinter, POIWG #34, July 2013 – 20 Glenn Research Center ZIN Technologies Flight Note F052537B Summary/Highlights POIC and Payload Facility teams will use non-invasive recovery techniques to attempt to recover an anomalous situation, even for new anomaly signatures, using approved documentation (with Flight Director “Go”) POIC and Payload Facility team will not use invasive recovery techniques to attempt to recover without MER approval Definitions were provided for Standard and Urgent notification criteria and Standard and Urgent Support Requests MER initiates and leads anomaly investigations for OB-managed facilities that require MER support to resolve As necessary, FITs, ARTs, and IFIs to document the problem and manage its resolution
21
FCF PAR Splinter, POIWG #34, July 2013 – 21 Glenn Research Center ZIN Technologies Flight Note F052537B Summary/Highlights The POIC PAR is the primary system for documenting Payload Facility anomalies, and their resolutions PARs are opened during real-time operations by the POIC flight control team, and assigned to the Payload Facility team for description, investigation, and resolution In parallel, the MER may also open an IFI to document engineering investigations, root cause and recurrence control. PIRATe will maintain Payload Facility IFIs with inputs from the associated PAR and Payload Facility team POIC will open a PAR for every new payload anomaly, however not every PAR will require an IFI PARs are used by POIC in real-time, because they define approved actions in response to known anomalies. In the event of a discrepancy, PARs will take precedence over IFIs PAR and IFI closure are not linked. Either one may stay open while the other is closed per current POIC and MER processes. MER Mgr concurrence for closure will be added to the PAR form
22
FCF PAR Splinter, POIWG #34, July 2013 – 22 Glenn Research Center ZIN Technologies Flight Note F052537B Summary/Highlights The agreements from the previous two previous slides have worked well for FCF over the past nine months FITs have been held to document problems and have been a big help in obtaining necessary resources, particularly crew time, to resolve problems more quickly –IOP hard drive change out –MDCA needle and reservoir issues –Non-FCF problem with SAMS JEM sensor and LEHX power cycle Decisions on whether a FIT is necessary have been worked on a problem by problem basis FCF team has concerns about possible changes to the previous agreements based on OB management concerns with the F052537B guidelines, particularly opening IFIs per the existing OB criteria Guarantees having to maintain paper in two different systems Would migrating payload facility problems from PAR-centric to IFI-centric assist in problem resolution?
23
FCF PAR Splinter, POIWG #34, July 2013 – 23 Glenn Research Center ZIN Technologies PAR/IFI Simple Guidelines FCF Perspective PARs and IFI decision based on the rack to ISS systems interface IOP and EPCU are the only electronic boxes with an ISS interface –Commands, all telemetry, water, power PARs assigned for problems that occur at the rack to ISS interface looking inward –Internal rack expertise lies with the FCF team for any rack internal problems PARs with an IFI should be considered for problems at the rack to ISS interface looking outward –Pending an initial problem investigation by FCF team, an IFI would make sense to control additional troubleshooting of hardware external to the rack, i.e., ISS systems This approach is largely how problems have been managed over the past several months

59
FCF PAR Splinter, POIWG #34, July 2013 – 59 Glenn Research Center ZIN Technologies FCF Operational Controls Command Verifications –Each command is echoed back in Command Status (CS) telemetry CS telemetry shows command status states like Received, Queued, Executing, Complete, Abnormal End –Daily Operations Plan calls out specific telemetry end items to verify for each command –Subsequent commands are not transmitted without the completion of the Daily Operations Plan command verification steps with a few exceptions… For example: File Uplink command breaks small files into pieces and re- assembles them on orbit. These commands are queued to send 1 per second automatically. CS telemetry verifications still exist, but are not a gate to allowing the next File Uplink command to be released FCF Console Operations

65
FCF PAR Splinter, POIWG #34, July 2013 – 65 Glenn Research Center ZIN Technologies FCF Off-Nominal Conditions CIR IPSU Power Cycles Detailed explanation of IPSU operations on GMT 2012/135 (May 14, 2012) All rack communications, whether external (looking out to ISS) or internal (looking in to CIR rack), are managed by the Input/Output Processor (IOP) All test point operations are initiated by the Multi-Droplet Combustion Apparatus (MDCA) Automated Sequence (AS) Each command to an IPSU originated by the AS experiences multiple “hops”, specifically MDCA to IOP, IOP to IPSU, IPSU back to IOP, IOP back to MDCA. If the command response does not return to the MDCA in the prescribed amount of time, the AS aborts –Recovery step for the problematic IPSU is a power cycle –Auxiliary Procedure I.4, Recover from MDCA Automated Sequence Abort on Imaging Failure contains the detailed recovery steps and anomaly logging instructions –The root cause of the loss of command response has been investigated extensively, but is unknown. No additional effort is planned to determine the root cause –This problem existed prior to CIR launch

FCF PAR Splinter, POIWG #34, July 2013 – 66 Glenn Research Center ZIN Technologies FCF Off-Nominal Conditions CIR IPSU Power Cycles Detailed explanation of IPSU operations on GMT 2012/135 (May 14, 2012) It is important to note that all other IPSU indications are nominal, including nominal telemetry communication and nominal command response to ground commands Experience has demonstrated an IPSU power cycle provides the greatest chance for proper AS behavior when the next AS is initiated The AS abort scenario has another important consideration –Fuel is still deployed and the IPSU recovery needs to be completed as quickly as possible to improve the likelihood of executing a successful test point –A timely power cycle is required because: If the fuel evaporates too quickly, the droplet can be lost completely from the needle tips If the fuel evaporates enough, a vapor cloud can form around the droplet making ignition difficult or impossible –Fuel is a precious commodity, with each fuel reservoir holding only 2 ml of fuel Quick action is extremely important to not waste fuel!
