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.
