Battery Charger Fault Codes

If a fault occurred during charging, the red "Fault" LED will
flash with a code corresponding to the error. Refer to the
table following for the flash codes and their removal.
Table 3-3. Battery Charger Fault Codes (Delta-Q)
Flash(s) Fault
Battery voltage Auto-recover - Indicates a high battery pack voltage

high
Auto-recover - Indicates either a battery pack failure,
Battery voltage battery pack not connected to charger or battery volts
2
low per cell is less than 0.5 VDC. Check the battery pack and
connections
Indicates the batteries did not charge in the allowed
Charge time. This could occur if the batteries are a larger capac-

time-out ity than the algorithm is intended for or if the batteries
are damaged old or in poor condition.
Indicates the batteries could not be trickle charged up to
4 Check battery the minimum voltage per cell level required for the
charge to be started.
Over- Auto-recover - Indicates charger has shut down due to

temperature high internal temperature
Indicates that the battery will not accept charge current,
or an internal fault has been detected in the charger. This
fault will nearly always be set within the first 30 seconds
of operation. Once it has been determined that the bat-

teries and connections are not faulty and fault 6 is again
displayed after interrupting AC power for at least 10 sec-
onds, the charger must be brought to a qualified service
