I am from Serbia, an electrical engineer, I work in the repair of medical devices, I have a mammograph Fuji amulet S, which broke down in our hospital, its generator is faulty, a DRGEM generator MXR35, more precisely an IGBT transistor module Semix202GB128DS. Please, if you can, help me get that module, I need it very quickly. Thank you very much
Displayed messages: W52 mA Low – E41 PRE HEAD HIGH
The generator is capable of performing X-ray exposures; however, an anomaly occurs when the exposure time exceeds 10 milliseconds. For exposures shorter than 10 ms, the mA readings are accurate. When the exposure time goes beyond that threshold:
- The mA current drops below the value set in the configuration parameters.
- The warning W52 mA Low appears.
- After a short delay, the error E41 PRE HEAD HIGH is triggered, causing the system to lock.
I would appreciate guidance on the recommended procedure to evaluate this fault. Are there specific tests or diagnostic steps to verify the generator’s behavior during longer exposures? Which components or parameters should be prioritized for inspection—particularly regarding mA regulation or the pre-head circuitry?
Any technical suggestions to help resolve this issue would be greatly appreciated.
