Optimus
Error Code: Type: Segment:
03HB Error/Warning
 

Description:

Intermediate circuit voltage < 200 V
 
Possible Causes / Advice:

Mains phase 2 present?

Check the fuses F3 and F1+2 where present.

With a PC and XRGSCOPE:
Select error # from error log index list, select screen Error: Read HW Values to get the faulty value.

Switch the generator off and wait about 1 minute before removing PCB EZ119!! Attention High Voltage !! Put PCB on extender and turn on. Measure with a multi meter at EZ119 capacitors C18/19/20, should be 325VDC +/-10%.

Has the modification on EZ119 (versions with 3 fuses) with a 33nF capacitor parallel to triac V36 been carried out which comes with the firmware upgrade kits for release 2 and 3? (optical check: big flat capacitor at the soldering side of the PCB)

Check supply voltages EZ119

  • + 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.
