    8.4 Programming Devices The enAble50 control unit is programmable, this means that the settings for the various pro- grammable parameters can be set using a programming device. Two programming devices are available: a handheld programming device and a PC programming station (PCPS). The PCPS has additional functions not offered by the handheld programming device.
  • Page 88 Initial operation: 1. Turn on the wheelchair control. 2. Ensure the cable is securely connected to the handheld programming device. 3. Connect the bus plug of the handheld programming device to a free bus receptacle (e.g. on the bottom of the display module). Operation: a) Display The interface is displayed using a so-called “menu tree”.

  • Page 89: Pc Programming Station (Pcps)

    Always test the driving characteristics of the power wheelchair after configuration / programming is complete. Programming must only be completed by authorised personnel.
