Table 3-3. Inverter Fault Codes
Error Code Error Condition Error Description Corrective Action
1
Wrong Config Eeprom memory not configured. Contact JLG.
8
Watch Dog The inverter is not able to
activate or turn off the electric
motor. Control connections and
continuity of the electric motor. If
they are OK replace the inverter.
8
Flash Checksum Software is corrupted or inverter
is damaged. Replace the inverter.
13
Eeprom KO Hardware or Software problem in
Eeprom. Replace the inverter.
16
Aux output KO Electromechanical brake
problem. Usually it is a temporary anomaly
due to a working condition. In
case the anomaly persists replace
the inverter.
17
Logic failure #3 Activates in case of high peak of
current in the inverter. Usually it is a temporary anomaly
due to a working condition. In
case the anomaly persists replace
the inverter.
18
Logic Failure #2 Fault in the inverter. Replace the inverter.
19
Logic failure #1 An overvoltage or a sudden
voltage drop occurred. Usually it is a temporary anomaly
due to a working condition. In
case the anomaly persists replace
the inverter.
26
Current Sens KO Current sensor for the motor
phases is damaged. Replace the inverter.
27
Phase KO One of the motor phases is open. Check the connection from the
inverter to the motor.
28
Pump Vmn Low Pump motor output is too low. Check the electric motor
connection.
29
Pump Vmn High Pump motor output is too high. Check the electric motor
connections.
30
VMN low Inverter supply voltage is lower
than the batteries’ one, or the
connection with the positive
terminal of the battery is not
correct. Control the connection with the
positive terminal of the battery. If
the anomaly persists, replace the
inverter.
31
VMN High One motor phase is not correctly
connected or is broken. Control motor phases and motor
internal connections. If the
anomaly persists, replace the
inverter.
37
Contactor closed The relay remains closed with
power to the coil disconnected. Control the relay.
38
Contactor Open The inverter supplies power to
the relay coil, but the contact
does not close. Control the relay and the power
to the coil.
40
Aux driv Shrt When the mos of EB is shorted. Check the battery feed.
