SECTION 4 - MACHINE OPERATION
3121165 – JLG Lift – 4-9
NOTE: If the charger is left plugged in, the charger will automati-
cally restart a complete charge cycle if the batteries volt-
age drops below a minimum voltage or 30 days has
elapsed. Battery Charger Fault Codes
If a fault occurred during charging, the red "Fault" LED will flash
with a code. The number of flashes corresponds to the error.
Refer to Table 4-1, Battery Charger Flash Codes.
Table 4-1. Battery Charger Flash Codes
Flash(s) Fault Fault Removal
1 Battery voltage high Auto-recover - Indicates a high battery pack voltage
2 Battery voltage low Auto-recover - Indicates either a battery pack failure, battery pack not connected to charger or battery volts per cell is less than 0.5 VDC.
Check the battery pack and connections
3 Charge time-out Indicates the batteries did not charge in the allowed time. This could occur if the batteries are a larger capacity than the algorithm is
intended for or if the batteries are damaged old or in poor condition.
4 Check battery Indicates the batteries could not be trickle charged up to the minimum voltage per cell level required for the charge to be started.
5 Over-temperature Auto-recover - Indicates charger has shut down due to high internal temperature
6 QuiQ fault 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 batteries and connections are not faulty and fault 6 is
again displayed after interrupting AC power for at least 10 seconds, the charger must be brought to a qualified service depot.
