Question
How do I troubleshoot this AMX-4 Series issue: Display issues, trashy, scrolling or no display during charge?
Short Answer
Monitor LVLE +5 V with an oscilloscope for about 15 minutes and look for breakup/noise on the +5 V supply. If noise is evident, replace the LVLE. If LVLE appears OK, check the Display kV/mA Charge Bar Board (Kit Part #2139946) or Display Controller Board (Part #46-264982G1). Battery Charger Board failure is also possible; tap on relays to see if display failure occurs. Solution: replace LVLE Power Supply, Display kV/mA Charge Bar Board, Display Controller Board and/or Battery Charger Board as indicated by troubleshooting.
Possible Causes
Problem: Display issues, trashy, scrolling or no display during charge.
Troubleshooting Steps
Monitor LVLE Power Supply +5 volt with a scope for about 15 minutes - look for break-up (noise) on +5 volt supply, If noise is evident, replace the LVLE Power Supply. If LVLE Power Supply appears OK, this could also be caused by a bad Display Board (replace with orderable kit Part # 2139946) or Display Controller Board (Part # 46-264982G1). Also could be possible Battery Charger Board failure. Check tap on relays to see if display failure occurs. Replace LVLE Power Supply, Display kV mA Charge Bar Board, Display Controller Board and/or Battery Charger Boards

Drive calibration required
Error Code System Message
HNDL CAL ERR 1-4
Question
When should I run AMX-Series drive-handle calibration?
Short Answer
Drive-handle calibration is required when the drive handle/transducer range or zero point is incorrect or related HNDL CAL errors occur.
Possible Causes
Handle transducer replacement/misalignment; calibration drift.
Troubleshooting Steps
Enter service calibration mode, perform the Drive Handle Calibration procedure, and confirm zero/forward/reverse values are within range before returning the unit to service.
Parts Areas to Check
Drive handle; Hall-effect transducers; CPU inputs
