Error Code: Type: Segment:
02HU Warning
 

Description:

divider test anode out of range: <45.5 kV or >50.5 kV

3 detections within 30 ms

During prep the converter sends a 3mS test pulse to the HT tank and then looks for a 48KV feedback. If the feedback is outside of the above listed factor an error is generated.

 
Possible Causes / Advice:

Connect an oscilloscope to EZ130:X3 (AV_HT_AN) and EZ130:X4 (AV_HT_CA) and monitor the prep test waveform.

Check supply voltages EZ130

  • + 5V X2:AC1 X2:AC2
  • +15V X2:AC11
  • - 15V X2:AC12
  • +26V X2:AC14
    against ground X2:AC15

If the waveforms and power supplies are correct replace the EZ130 PCB.
