Error Code: Type: Segment:
02HH Error
 

Description:

kV actual value out of range 20kV > U > 170kV

3 measurements within 30ms

 
Possible Causes / Advice:

If this error occurs in combination with 02HG, 02WK, & 00XO see Service Recommendation 00 135 015

With a PC and XRGSCOPE:
select error # from error log index list, select error details and read screen Error: HW Set Values to get KV nominal, then read Error: Read HW Values to get the faulty value.

Monitor with oscilloscope at EZ130 X3 AVHT 20kV/V or X4 (anode) and X5 (cathode).
trigger: CTRL_X_C/ EZX74

Check mains conditions.

Release 2 generators:

  • Check kV behavior against document kV1_2_mod.doc and carry out modification if necessary
  • Carry out kV driver test chapter 8.2 FAULT FINDING

Release 3 generators:

  • Check and carry out adjustment "factor for duty" cycle according to document adj_duty_cycle_factor.doc
  • Carry out kV driver test chapter 5.3 register Converter R/F
  • Check if FCO 00 135 014 has been carried out

All Generators
Check mains conditions.

Check supply voltages EZ130

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

If values indicated at the detail screens do not match the externally measured ones exchange PCB.
