Battery Charger Fault Codes; Battery Charger Flash Codes - JLG 1930ES Operation And Safety Manual

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.
Flash(s) Fault
1 Battery voltage high
2 Battery voltage low
3 Charge time-out
4 Check battery
5 Over-temperature
6 QuiQ fault

Table 4-1. Battery Charger Flash Codes
Auto-recover - Indicates a high battery pack voltage
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
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.
Indicates the batteries could not be trickle charged up to the minimum voltage per cell level required for the charge to be started.
Auto-recover - Indicates charger has shut down due to 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 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.

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.
