What to do if my JLG X770AJ-X26JP Boom Lifts battery charger shows error code 252 (short-circuit in output)?
If the battery charger displays error code 252, indicating a short-circuit in the battery charger output, turn off the battery charger and resolve the short-circuit at the output.
What to do if my JLG Boom Lifts battery charger shows error code 244 because the mains voltage is too low?
If the battery charger shows error code 244, indicating that the mains voltage is lower than the maximum operating range tolerance, make sure the mains voltage is within the correct operating parameters. The battery charger won’t start charging until the mains voltage returns within the normal operating range.
What to do if my JLG X770AJ-X26JP Boom Lifts battery charger shows error code 240 because digital input is open?
If the battery charger displays error code 240, indicating that the digital input is open, the battery charger will stop charging until the digital input closes. Close the digital input to resolve this issue.
What to do if JLG X770AJ-X26JP Boom Lifts show Inverter Error Code 8 - Watch Dog?
If the JLG Boom Lifts shows Inverter Error Code 8 - Watch Dog, check the control connections and continuity of the electric motor. If they are OK, replace the inverter, because the inverter is not able to activate or turn off the electric motor.
What to do if JLG Boom Lifts show Inverter Error Code 19 - Logic failure #1?
If JLG Boom Lifts shows Inverter Error Code 19 - Logic failure #1, it is usually a temporary anomaly due to a working condition, caused by an overvoltage or a sudden voltage drop. However, if the anomaly persists, replace the inverter.
What to do if JLG X770AJ-X26JP show Inverter Error Code 16 - Aux output KO?
If JLG Boom Lifts shows Inverter Error Code 16 - Aux output KO, it is usually a temporary anomaly due to a working condition, caused by electromechanical brake problem. In case the anomaly persists replace the inverter.
What to do if JLG Boom Lifts show Inverter Error Code 8 - Flash Checksum?
If JLG Boom Lifts shows Inverter Error Code 8 - Flash Checksum, replace the inverter, because the software is corrupted or the inverter is damaged.
What to do if JLG X770AJ-X26JP Boom Lifts show Inverter Error Code 13 - Eeprom KO?
If JLG Boom Lifts shows Inverter Error Code 13 - Eeprom KO, replace the inverter, because there is a hardware or software problem in Eeprom.
What to do if JLG X770AJ-X26JP Boom Lifts show Inverter Error Code 18 - Logic failure #2?
If JLG Boom Lifts shows Inverter Error Code 18 - Logic failure #2, replace the inverter, because there is a fault in the inverter.
What causes BMS fault code 02 - Unexpected Voltage in JLG X770AJ-X26JP?
BMS fault code 02, "Unexpected Voltage," in JLG Boom Lifts is caused by the BMS failing to identify one cell or being unable to connect it to the discharging resistance. When one cell reaches 3650 mV, the BMS will disconnect the lithium pack, triggering this error.
