Incorrect charging duration
Fault F2x Cause Elimination
Main current phase I1 takes too
long; charging operation is aborted. F21
• Defective battery or incorrectly set charging
device
• Check the battery electrolyte density,
temperature, voltage of the individual cells
• Check the charging device settings
Phase with constant voltage
U1 takes too long; the charging
operation is aborted.
F22 • Defective battery or incorrectly set charging
device
• Check the battery electrolyte density,
temperature, voltage of the individual cells
• Check the charging device settings
Max. duration of I2 phase
exceeded.
F23
• Battery too greatly discharged
• Incorrect settings
• Faulty calibration of the charging device
• Check the electrolyte status
• Discharge to max. 80% of the battery
capacity
• Check charging device setting
• Recalibrate the charging device
Charging current deviations
Fault F3x Cause Elimination
Charging current <50% of the no-
minal value; the charging operation
is aborted.
F31
• For three-phase network, one phase missing
• Faulty power module
• Faulty calibration of the charging device
• Network check
• Function check of the power modules
• Recalibrate
Charging current >120% of
the defined value; the charging
operation is aborted.
F32 • Faulty power module
• Faulty calibration of the charging device
• Function check of the power modules
• Recalibrate
Charging current >120% of the
nominal value; the charging
operation is aborted.
F33 • Faulty power module
• Faulty calibration of the charging device
• Function check of the power modules
• Recalibrate
During the charging operation,
more than >120% Cnom is
delivered.
F34 • Incorrect battery
• Incorrect charging device settings
• Check the electrolyte status
• Discharge to max. 80% of the battery
capacity
• Check charging device settings
Communication of the control system
Fault F4x Cause Elimination
Communication error with the
power module.
F40
• Incorrect contact
• Control system error
• Module error
• Check the connection
• Repair/replace the control system
• Repair/replace the module
