Troubleshooting Steps - Otto Bock C2000 Service Instructions Manual

7.1 Troubleshooting Steps
For troubleshooting purposes, the control unit of the C2000 power wheelchair identifies the fol-
lowing categories depending on the effect of the malfunction on the system:
❒ Error
❒ Warning
❒ Defect
A warning indicates a status or malfunction of one or several individual components of the
C2000 power wheelchair.
All problems that have ever occurred are saved in a list and can be retrieved, e.g. in case of
a general overhaul of the C2000 power wheelchair. The saved data can be used to determine
future service and maintenance intervals, for example.
The following table shows the different error messages on the control panel display or separate
LCD monitor. On the LCD monitor, the error message also includes the identification number
of the error that has occurred (for more detailed information see the enAble50 instructions for
