AMX Troubleshooting & Technical Support

Results Count

Error Number

Field light on-time issue

Error Code System Message

FLDLT TIME LIMIT / FLDLT BYTE LIMIT

AMX field light timer, FLDLT TIME LIMIT
Question

How does the AMX-Series field light timing work?

Short Answer

The field light is controlled by a calibrated on-time and may remain on for a limited period after the switch is released; software imposes a maximum on time.

Possible Causes

Field-light timer calibration or switch/control issue.

Troubleshooting Steps

Verify field-light switch operation and calibrated on-time. If the light does not time out or shuts off prematurely, inspect the field-light timing/calibration path.

Parts Areas to Check

Field light; CPU timing/calibration

Error Number

Filament-current table problem

Error Code System Message

HIGH FIL LIMIT / LOW FIL LIMIT / FIL feedback errors

AMX high filament limit, low filament limit, filament calibration
Question

How do I troubleshoot AMX-Series filament-current calibration limits?

Short Answer

The filament table is calibrated at specific kVp points and emission-current targets, with interpolation between calibrated points.

Possible Causes

Filament feedback calibration; table-point limit; tube aging; kVp feedback issue.

Troubleshooting Steps

Verify filament feedback, tube/cathode connections, kVp feedback and calibration points. Repeat the affected point and continue only after values stay within limits.

Parts Areas to Check

Filament circuit; X-ray tube; generator control

Error Number

Generator fault during prep/exposure

Error Code System Message

ERROR 320-469

AMX generator fault, ERROR 430, ERROR 469, no exposure
Question

How should I troubleshoot an AMX-Series generator fault?

Short Answer

The application generator errors identify which part of the prep/exposure sequence failed, including field light, rotor, tap relay, kVp, filament, X-ray-on, pressure switch, timing, and interlocks.

Possible Causes

Generator control sequence did not receive the expected feedback or timing.

Troubleshooting Steps

Record the exact 3-digit/hex application error. Check the corresponding critical-status signal, interlock, relay, feedback path, or calibration indicated in the table before replacing components.

Parts Areas to Check

Generator control board; CPU board; rotor; inverter; filament; tap relay; HV circuits

Question

What does HANDLE CAL ERR 4 mean on a GE AMX-Series mobile X-ray?

Short Answer

HANDLE CAL ERR 4: Handle calibration sequence failed.

Possible Causes

Drive handle calibration aborted or did not complete correctly.

Troubleshooting Steps

Return handle to correct position, verify calibration sequence and repeat.

HIGH FIL LIMIT

Error Code System Message

HIGH FIL LIMIT - High filament-current calibration limit exceeded

HIGH FIL LIMIT, High filament-current calibration limit exceeded, AMX-4 HIGH FIL LIMIT, AMX-4+ HIGH FIL LIMIT, Definium AMX 700 HIGH FIL LIMIT, GE AMX error HIGH FIL LIMIT
Question

What does HIGH FIL LIMIT mean on a GE AMX-Series mobile X-ray?

Short Answer

HIGH FIL LIMIT: High filament-current calibration limit exceeded.

Possible Causes

One or more filament-current calibration parameters exceeded the high limit.

Troubleshooting Steps

Verify filament current, mAs/kVp calibration and tube connections; repeat filament calibration.
