Fault tracing 183Fault messagesCode(hex)Fault Cause What to do2E00 Overcurrent Too high inverter load or shortcircuit.Check the load and busbars.2E02 Short circuit DC/DC converter has detectedshort circuit.Check supply cable.Check there are no power factorcorrection capacitors or surge absorbersin supply cable.Check the auxiliary code (format XXXYYYZZ). With parallel-connected modules,“Y YY” specifies through which BCUcontrol unit channel the fault wasreceived. “ZZ” indicates the location ofthe short circuit (0: No detailedinformation available, 1: Upper branch ofU-phase, 2: Lower branch of U-phase,4: Upper branch of V-phase, 8: Lowerbranch of V-phase, 10: Upper branch ofW-phase, 20: Lower branch of W-phase,other: combinations of the above).After correcting the cause of the fault,reboot the control unit (using parameter196.08 Control board boot) or by cyclingpower.2E04 IGBT overload Excessive IGBT junction tocase temperature.Check the load.2E05 BU current difference Phase current differencebetween parallel-connectedmodules.Check cable connections.Check mains supply and fuses.2E08 External earth fault External earth fault trigged byinput selected with parameter131.28 Ext earth leakagesignal source.Check external earth fault source.Usually only one device is allowed in thesame network.2E0C User current fault Sum current of the threephases has exceeded the limitdefined with parameter 131.25User current fault limit.Check the value of parameter 131.25User current fault limit.Check current limits of parameters130.119 Minimum current and 130.120Maximum current.Check that the DC bus voltage is notdropping (against the energy storagevoltage) so that the current can flowuncontrolled from the energy storage tothe DC bus via the freewheeling diodes.3E00 Input phase lossProgrammable fault:131.21 Supply phase lossInput phase loss detected bythe IGBT bridge.Check the AC fuses.Check for input power supply imbalance.3E04 DC link overvoltage Excessive intermediate circuitDC voltageCheck that parameter 195.01 Supplyvoltage is set according to the supplyvoltage in use.With parallel-connected modules,check the auxiliary code (format XXXYYYZZ). “Y YY” specifies through whichBCU control unit channel the fault wasreceived.
