Troubleshooting
Operating errors appear as safety codes in the display. To determine the problem, look up the
code in the table below. Correct the error. If errors continue, contact FMA Customer Service.
SAFETY CODE 23
Push to Reset
Typical error message
Code Cause Resolution
1 Low-cell-voltage timeout on startup Try charging again no more than 2 times. Cell may
have internal short.
2 Input voltage below 10 volts Lower charge amps, get a bigger power source
(power source must output at least 5A).
3 Input voltage above 16 volts Power source voltage is too high. Lower voltage.
4 Input voltage unstable Power source is too small. Lower charge current.
Check for loose connections or thin wires.
5 Cell voltage above 4.30 volts Discharge pack.
6 Cell removed too many times
(charger attempted to charge,
but failed) or red node wire not
connected
Ensure red (pack +) wire is properly connected.
If error continues, pack or charger may have a
problem.
7 Bad mode number Factory error. If error persists, send charger for
repair.
8 Checksum error Factory error. Send charger for repair.
9 Overcurrent Power source may be unstable. If power source
voltage is stable, send charger for repair.
13 Overvoltage shutdown Factory error. If error persists, send charger for
repair.
14 Bad EEPROM write Factory error. If error persists, send charger for
repair.
15 System soft start Check for bad power connection or low source
voltage.
16 Firmware corruption Factory error. If error persists, send charger for
repair.
17 Cell voltages don’t total correctly Cycle charger power. Pack may have a bad cell.
Ensure red node wire is properly connected.
18 Cell balancing stopped after 8 hours Raise charge current. Pack may be bad, or too big.
20 Fast charge stopped after 8 hours Raise charge current. Pack may be bad, or too big.
21 Bad cell count Check individual cell voltages (each cell must be
above 0.5V).
22 Charge current too low If pack is not full, try raising current above 1A.
23 Pack detect ran 8 times without
finishing a single charge
Pack may have bad cell.
Check individual voltages. If one cells is full and
another cell is empty, pack cannot be safely charged
24 Cell dropped below 3 volts during
charge
Pack may have bad cell.
28 Pack detect failed Check individual cell voltages (each cell must be
above 0.5V). Ensure all node wires are properly
connected to cells, and black (pack –) node wire is
properly connected. Ensure battery ground is not
connected to power source ground. Charger may
be wet.
A123 pack drained to 0V may have damaged cell.
