Exception Handling (LS16, Ultra, Plus)

1 Functional Overview

JEDI software performs auto-test at power up and continuously monitors the correct operation of its functions during application. Any malfunction is stored in the Jedi errorlog and reported to the system through a protocol that vehicles error code.

2 Diagnostics

There are different levels of diagnostics:

2.1 Power On Diagnostics

At power up, the kV control board performs its own initialization, checks its memory integrity (Checksum of program and NVRam), and starts the communication with its peripherals and the system; Communication is permanently checked afterwards. Then it initializes the Rotation board and Heater board with their respective Data base parameters and loads the kV control board's FPGA.

8 LEDs (DS17..DS24) on kV control board show the software status.

During power on, the Heater board and the Rotation board CPU's initialize themselves and check their memory integrity and hardware. If a problem is encountered, a PRD (Power Reset Diagnostics) error is reported to the kV control board.

2.2 Alive Diagnostics

2.2.1 Under Application

Faults will be reported through an error code and associated message.

2.2.2 Diagnostics Run Separately

  • Heating without HV nor rotation

  • Rotation without HV nor filament

  • Inverter gate command diagnostic

  • Inverter in Short circuit diagnostic

  • No load kV without anode rotation nor filament heating

2.2.3 Manual Diagnostics

See Troubleshooting section for more detail.
