Troubleshooting AMX

Error Number
Error 465
Error Code / System Message
465
Error Question
What should I check for error 465 on the AMX-4 Series?
Short Answer
1) Check J2 plug from T2 on AMX1A4 panel and clean J3 on Filament kVp Board. 2) Filament kVp Board may be defective. 3) Batteries may be soft. Perform load test. BATTERY VOLTAGE MUST BE 113 V OR LESS TO DO LOAD TEST; DO NOT CHARGE BATTERIES BEFORE LOAD TEST. a) Connect oscilloscope from circuit breaker to ground; use Sample mode. b) Make exposures at 80, 100 and 125 kVp, about 10 mAs. c) Read battery voltage and average ripple at bottom. d) Battery voltage should drop about 13 VDC +/-10% at 80 kVp. e) About 16 VDC +/-10% at 100 kVp. f) About 17 VDC +/-10% at 125 kVp. 4) If batteries pass load test, unit may require recalibration of mAs, kVp, taps and filament current tables. 5) If batteries do not pass load test, replace batteries.
Possible Causes
1. Check J2 Plug From T2 On AMX1A4 Panel/Clean J3 On Filament kVp Board 2. Filament kVp Board may be defective 3. Batteries May Be Soft. Perform The Load Test. BATTERY VOLTAGE MUST BE 113 VOLTS OR LESS TO DO LOAD TEST! DO NOT CHARGE BATTERIES BEFORE LOAD TEST!! a. Connect Oscilloscope From Circuit Breaker To Ground - Use Sample Mode b. Make Exposures At 80, 100 kVp And 125 kVp, About 10 mAs c. Read Battery Voltage And Average The Ripple At The Bottom d. Battery Voltage Should Drop About 13 VDC +/-10% At 80 kVp e. Battery Voltage Should Drop About 16 VDC +/-10% At 100kVp f. Battery Voltage Should Drop About 17 VDC +/-10% At 125kVp 4. If Batteries Pass Load Test, Unit May Require Recalibration Of mAs, kVp, Taps And Filament Current Tables 5. If Batteries Do Not Pass The Load Test, replace batteries
