With a PC and XRGSCOPE:
select error # from error log index list, select screen
Error: HW Read Values and check the E value.
Measure with multi meter at ENK2:41 & 42 when generator is
on and ENK1 energized!!
Attention High Voltage !!
This error has been know occur on sites with bad power, especially
when the unit sits idle for long periods of time. Voltage spikes
can charge the caps in the converter and if no exposures are taken
the caps will continue to charge with each spike until the error
is generated. Monitor power to confirm this situation.
This error might appear after a converter damage, breakers and
fuses might have been on after the event. If the generator was turned
on with a short in converter which lets the damping resistors ENR1...3
open the springs (can be soldered on again). If ceramic body is
cracked exchange damping spring resistor version dependent:
- R2 generators with 100 Ohm resistors (horizontal mounting) 4512-100-4494.
- R2+3 generators with 47 Ohm resistors (vertical mounting) 4512-100-45441.
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.
