5. Troubleshooting

General malfunctions
Fault
JLA-e cannot be switched on
JLA-e cannot be moved or only
on one side
If repairs become necessary after years of extreme use, we will give you a cost estimate and repair the system on short notice
and at low cost. Address information can be found on the rear side of the operating instructions.
Poor starting conditions, battery malfunction, high battery temperature
Fault
The battery voltage is lower than
98% Unom of deep-discharging
battery.
Battery disconnected without
ending the charging operation with
the STOP key.
Battery temperature >TbatMAX:
• 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 operati-
on, the charging current is reduced
to the input value and the charging
process is continued. Once the tem-
perature has dropped to (TbatMAX-
2)°C, the charging current increa-
ses again to the input value I1.
