Error Number
Battery capacity appears lower with age
Error Code System Message
Question
How does AMX-Series battery aging compensation work?
Short Answer
The firmware can reduce displayed available capacity as batteries age so the bar graph better reflects usable capacity under generator load.
Possible Causes
Aged batteries; battery-aging parameter not updated.
Troubleshooting Steps
Review battery-aging capacity settings and real battery performance under load. Use the service data-base access only as directed; do not overwrite aging data indiscriminately.
Parts Areas to Check
Battery set; CPU data-base parameters

Battery charging complaint
Error Code System Message
BATTERY ERROR x / CHARG x / ERROR 101-107
Question
How should I troubleshoot an AMX-Series battery charging complaint?
Short Answer
Verify charger current feedback, battery voltage, charger calibration, and whether the system transitions through the expected charging phases.
Possible Causes
Low battery SOC; charger feedback/calibration error; charger-board/CPU interface issue; battery aging.
Troubleshooting Steps
Review charging error codes, verify battery voltage and charger-current display, and perform charger/voltmeter calibration checks before replacing batteries or charger hardware.
Parts Areas to Check
Batteries; charger board; CPU board; charge-current feedback

Error Number
Battery voltage drops during exposure
Error Code System Message
Question
How do I determine whether AMX-Series batteries are weak under load?
Short Answer
The manual recommends checking battery voltage drop under a lower state of charge; an excessive average drop during prep/exposure indicates a weak battery set.
Possible Causes
Aged/weak batteries; low state of charge; excessive load.
Troubleshooting Steps
Lower the battery charge to the manual's test range, monitor battery voltage during prep/exposure, and compare the average voltage drop with the manual's criterion before condemning the battery set.

Error Number
Battery voltmeter calibration required
Error Code System Message
VOLTMETER ERR 1/4; BATTERY ERROR 1-4
Question
What does AMX-Series battery-voltmeter calibration do?
Short Answer
It establishes the relationship between actual battery voltage and VCO frequency so the CPU can convert measured frequency into battery voltage.
Possible Causes
Battery-voltage display/calibration mismatch.
Troubleshooting Steps
Perform voltmeter calibration when VOLTMETER or BATTERY calibration errors occur, then verify displayed voltage against an external meter.
Parts Areas to Check
Battery-voltage VCO; CPU; charger board
