VOLTMETER ERR 1
Error Code System Message
VOLTMETER ERR 1 - Battery-voltage VCO frequency too high
Question
What does VOLTMETER ERR 1 mean on a GE AMX-Series mobile X-ray?
Short Answer
VOLTMETER ERR 1: Battery-voltage VCO frequency too high.
Possible Causes
Battery-voltage frequency/count exceeded calibration range.
Troubleshooting Steps
Check charger-board frequency and VCO/battery-voltage calibration.

X-RAY ON
Error Code System Message
ERROR 436 / 437 / 439 / 443 / 469
Question
What should I check when the AMX-Series X-RAY ON status does not match the exposure state?
Short Answer
Several application errors are generated when X-RAY ON is asserted at the wrong time or is missing when expected.
Possible Causes
X-RAY ON signal wiring; status-port fault; generator control or inverter sequence problem.
Troubleshooting Steps
Check the X-RAY ON signal at the Critical Status port, verify the CPU connection and generator-control timing, and inspect the related relay/inverter command path.
Parts Areas to Check
Generator control board; CPU board; X-ray status line
