HVREX_a032 — Shunt Asic Mia HVREX_a032_ShuntAsicMia The shunt measurement ASIC is not producing data
HVREX_a038 — Shunt Asic Comms HVREX_a038_ShuntAsicComms Sets immediately on SPI comms errors for visibility into the health of the comms interface
HVREX_a017 — Shunt Asic Cal Not Used HVREX_a017_ShuntAsicCalNotUsed The programmed shunt application-specific integrated circuit (ASIC) calibration is not being used for high voltage (HV) current sensing. The default shunt ASIC gain will be used and current measurement accuracy may be reduced.
HVREX_a207 — Shunt Disconnected HVREX_a207_ShuntDisconnected Shunt detects shunt connector as disconnected
HVREX_a037 — Shunt Over Current HVREX_a037_ShuntOverCurrent Warns if the shunt current (discharge or charge) is above max current limit.
