Error Question
What should I check for error 466 on the AMX-4 Series?
Short Answer
1) During calibration, take unit out of calibration and reset CPU, then restart Generator Calibration (mAs, kVp, taps and filament current table). 2) Check spark gaps on HV Transformer Tank for 0.010 in. setting. 3) Check for miswired or open plug J2 from T2 on AMX1A4 panel to HV Transformer Tank mA+ & mA-. 4) Check for HV Transformer Tank spits. 5) Check for X-Ray Tube HV spits. 6) CPU Board may be defective. 7) On older units, insulate capacitor C5 from its retaining clamp (Service Note 3265).
Possible Causes
1. During Calibration, Take Unit Out Of Calibration And Reset CPU Then Restart Generator Calibration (mAs, kVp, Taps, And Filament Current Table) 2. Check Spark Gaps On HV Transformer Tank For A 0.010” Setting 3. Check for miswired Or Open Plug J2 From T2 On AMX1A4 Panel To HV Transformer Tank MA+ & MA- 4. Check for HV Transformer Tank Spits 5. Check for XRT HV Spits 6. CPU Board may be defective 7. Insulate (On Older Units) Capacitor C5 From its Retaining Clamp (Refer to Service Note 3265)
