MOMA Alerts

A MOMA Alert is defined as a notification of certain parameters of interest in a single MOMA Test. This page details the logic we use to extract the data for each alert. Note that this is the master reference, which means the engineers and scientists should ensure that the logic detailed here is correct. All alert data is in an Alert Panel within a typical TID record __TOC__

General Error Check

Severity : Notice

  • Message Log is parsed for the phrase 'Error' while excluding messages that contained 'Holding at stop for operator' or 'error =' <- Means a value was being set.

MAIF APV Comm Check

Severity : Warning

  • Message Log is parsed for the phrase 'ldi: error'.

Spacewire Comm Error

Severity : Warning

  • Spacewire Disconnect (HK 522) > 0 or Spacewire Parity (HK 523) > 0 after 30 sec.

Severity : Notice

  • Spacewire Disconnect (HK 522) > 0 or Spacewire Parity (HK 523) > 0 only before 30 sec.

MOMA Safe Event

Severity : Notice

  • MOMA_STATUS_SAFE (HK 507) is 1 at any time during the TID.

WRP Too Fast

Severity : Notice

  • PWM Speed (HK 832) > 103000RPM at any time during the TID.

WRP Failed to Start

Severity : Warning

  • PWM Speed (HK 832) surpassed 1000RPM but never reached over 99000RPM at any time during the TID.

WRP Pressure Spike

Severity : Warning

  • MOT_SUP_IMON (HK 830) > 1.1A at any time during the TID.

Dark Counts

Severity : Warning

  • SCAN_TELEM_DAC_ID (HK 252) == 20000 and SCAN_TELEM_DAC_VAL (HK 253) > 5 at any time during the TID.

Laser Burst Energy Variation

Severity : Info

  • Standard Deviation of the Energy from all Pulses in a Single Burst > 5.0

Severity : Notice

  • Number of Main Pulses Commanded (HK 1002) != # of Pulses in the Burst

Unknown SEB Sequences

Severity : Notice
