Jung JLA-e 5/12 G Mode D'emploi page 56

Poor starting conditions, battery malfunction, high battery temperature
Fault
Temperature in charging device
>65°C:
• If the battery temperature is
higher than the defined setpoint
when connecting to the charging
device, the charging operation is
not initiated
• If the temperature exceeds
this value during the charging
operation, the charging current
is reduced to the input value and
the charging process is continu-
ed. Once the temperature has
dropped to (TbatMAX-2)°C, the
charging current increases again
to the input value I1.
Incorrect charging time
Fault
Phase with constant voltage U1
takes too long; charging operation
is continued with next phase.
During the charging operation,
more than 130% of the nominal
power was charged.
During the main charging phase
I1, more than 80% of the nominal
capacity was delivered.
Deviations from charging current I1
Fault
Charging current I1 <80% of the
nominal value.
Charging current I1 >110% of the
required value.

E1x Cause
• Ambient temperature too high
E14
• Charging device too dusty
E2x Cause
• Defective battery or incorrect charging
E22
device settings
• Defective battery or incorrect charging
E23
device settings
E24 • Deep-discharging battery
E3x Cause
• For three-phase network, one phase
missing
E31
• Faulty power module
• Faulty calibration of the charging device
• Faulty power module
E32
• Faulty calibration of the charging device
Elimination
• Reduce the ambient temperature.
• Thoroughly clean the charging device.
• If the charging device is equipped with a
dust filter, check this and replace, if
necessary.
Elimination
• Check the battery electrolyte density,
temperature, voltage of the individual cells
• Check the charging device settings
• Check the battery electrolyte density,
temperature, voltage of the individual cells
• Check the charging device settings
• Check the battery electrolyte density,
temperature, voltage of the individual cell
• Check the charging device settings
Elimination
• Network check
• Function check of power modules
• Recalibrate charging device
• Function check of power modules
• Recalibrate charging device
