9.3 Troubleshooting

CAUTION
Risk of uncontrolled driving behaviour
Falling, tipping, collision with persons or nearby objects due to defects
► If any faults, defects or other hazards that can lead to personal injury are detected, the product must be taken
out of service immediately.
► Contact your authorised specialist dealer if uncontrolled movement of the product occurs due to a malfunc­
tion.
INFORMATION
In the event of communication problems in the control unit bus system, the system triggers an emergency stop in
order to prevent any uncontrolled functions.
► Note that after every emergency stop, you have to turn the power wheelchair control unit on again.
► If the driving function is still not available after turning the control unit on again, activate pushing mode by
releasing the brake.
► Inform the qualified personnel immediately.
Faults are indicated on the control panel LCD screen, on the LCD monitor (if installed) or on the attendant control
(if installed). The following table shows the individual notifications as well as the associated fault sources and pos­
sible causes and measures.
If the measures described here do not resolve the faults completely, contact your specialist dealer. The specialist
dealer is able to read the exact error codes with a handheld programming device and can perform a targeted sys­
tem analysis.
The control unit stores a list of all faults that occur. The specialist dealer reads this information, for example during
a general overhaul of the power wheelchair. Based on the saved data, the specialist dealer determines future ser­
vice and maintenance intervals.

9.3.1 Types of notifications

Warning
A warning indicates a status or malfunction of one or several components of the power wheelchair. The function of
components without errors is not restricted.
For example, if the connection between the control unit and seat motor is faulty, this error will only be indicated if
the user attempts to activate the motor. However, the driving function is still available.
Error
An error affects one or several functions of the power wheelchair. The power wheelchair and its functions are not
fully operational until the fault is resolved.
