Error Number
TEST display stops on a number
Error Code System Message
TEST xx - FAILED
Question
What does it mean when the AMX-Series power-up display stops on TEST 00 through TEST 07?
Short Answer
The displayed TEST number identifies the startup diagnostic currently running; FAILED indicates that test did not pass.
Possible Causes
Subsystem corresponding to the displayed test failed.
Troubleshooting Steps
Record the exact TEST number. Use the Power-Up Error Codes table to identify the tested circuit and recommended checks. Do not bypass a failure unless following the manual's checksum-bypass service procedure.
Parts Areas to Check

Error Number
TURN RATIO LIMIT
Error Code System Message
TURN RATIO LIMIT - Turn-ratio calibration limit exceeded
Question
What does TURN RATIO LIMIT mean on a GE AMX-Series mobile X-ray?
Short Answer
TURN RATIO LIMIT: Turn-ratio calibration limit exceeded.
Possible Causes
Battery-voltage to kVp multiplication factor is outside range.
Troubleshooting Steps
Verify mAs/kVp calibration and transformer/tap relationships.
Parts Areas to Check
CPU board; calibration data; subsystem identified by the error

Error Number
Tap relay calibration problem
Error Code System Message
CAL TAP ERROR 1-7
Question
What is AMX-Series tap-relay calibration used for?
Short Answer
Tap calibration determines which transformer tap combinations are required to achieve the correct output across battery voltage and kVp conditions.
Possible Causes
Tap relay wiring; transformer/tap calibration; battery voltage effect.
Troubleshooting Steps
Run tap calibration and inspect the tap relay/transformer wiring when CAL TAP errors occur. Verify the selected combination and system-resistance parameters.
Parts Areas to Check
Tap relay board; transformer; generator control

Error Code System Message
Question
How do I troubleshoot this AMX-4 Series issue: There is a potential for ghosting to be seen on the Display Controller Board Part # 2409241 when used with the Display Board Part # 2345236 version. Ghosting results in partial illumination of some of the characters on t?
Short Answer
To prevent ghosting, remove Display Board Part #2345236 if the combination of Part #2345236 and Display Controller Board Part #2409241 is found. Replace the Display Board with Part #2345236-1. Whenever a replacement for the 46-264982G1 version of the Display Control Board is ordered, kit Part #5119876 contains a new version of both the Display Board (Part #2345236-2) and the Display Control Board (Part #2409241).
Possible Causes
Problem: There is a potential for ghosting to be seen on the Display Controller Board Part # 2409241 when used with the Display Board Part # 2345236 version. Ghosting results in partial illumination of some of the characters on the extreme left or extreme right of the display. While AMX4/AMX4+ systems exhibiting ghosting have not been shipped in forward production, this problem could occur in AMX4/AMX4+ systems if a service replacement part results in a non-desirable configuration of circuit boards. Applied to all AMX-4 and AMX-4+ models builds though October 2004.
Troubleshooting Steps
To prevent this problem from occurring, remove Display Board Part # 2345236 from unit if a combination of Part # 2345236 and Part # 2409241 is found. Replace Display Board with Part # 2345236-1. Whenever a replacement for the 46-264982G1 version of the Display Control Board is ordered, a kit (Part #5119876) containing a new version of both the Display Board (Part # 2345236-2) and the Display Control Board (Part # 2409241) will be sent.

Error Number
Tube spits during calibration
Error Code System Message
CALIBRATE TAPS
Question
What should I do if the X-ray tube spits during AMX-Series CALIBRATE TAPS?
Short Answer
At high kVp, the manual recommends slowing the calibration pace and waiting between exposures to allow the tube to recover.
Possible Causes
Tube spit during high-kVp calibration exposures.
Troubleshooting Steps
At higher kVp points, increase time between calibration exposures and wait for READY FOR X-RAY before continuing. If spits persist, stop and evaluate the tube/generator.
Parts Areas to Check
X-ray tube; generator
