Check contacts of high tension cable cathode plug pins at generator
and tube side, common connection poor if error during prep.
With a PC and XRGSCOPE:
Select error # from error log index list, select error details,
and read screen Error: Read HW Values to get the setpoint
and the faulty value.
- fil. circuit 1 = small focus
- fil. circuit 2 = large focus
Monitor with oscilloscope at:
- EZ119 X5 = small focus
- EZ119 X7 = large focus
1V = 2.5A filament current
Mains phase 2 present?
Try HT cable exchange if the actual ones very old / suspicious.
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 PC
