Restart After a Balancing Error

The device monitors a range of critical safety parameters during the balancing mode. In certain circumstances, the wheelchair can enter an emergency shutdown and exit drive mode automatically. The LED ring will then light up in red (see ). Proceed as follows to reactivate drive mode:

  1. Select park mode: See Selecting Park Mode.

  2. The interface lights up with two yellow arrow animations around the touchpad (see also User Interaction Prompts). Move the joystick forwards or backwards to return to park mode. You can interrupt the operation at any time by releasing the joystick.

  3. Reactivate drive mode

Control panel indicates that the joystick must be moved forwards or backwards

Possible causes of a balancing error

  1. Centre of gravity too far to the front/back (e.g. the wheelchair suddenly rolled forward): Adjust the center of gravity (e.g. change the angle of the back support, remove heavy objects from the backpack).

  2. Centre of gravity not calibrated (generally causes poor performance when balancing or braking). Recalibrate the center of gravity (see Calibrating the Center of Gravity)

  3. Exceeding the speed limit or the maximum inclination that can be driven on.

  4. System error
