Sensors
The sensor unit consists of the sensor and a
magnet. If the magnet is closer than 1.5 cm
to the sensor tip, no electrical energy can
flow through the sensor.
In a vehicle with lifter, information is passed
using the sensor unit to the lifter positioning
control and the seat tilting.

Status displays
Status displays are LEDs that point to errors in the
wheelchair's electrical installation by means of blinking.
The following joystick boxes have a status display:
• joystick box (standard)
• chin control
• table and central control
The ON/OFF LED's are designed as status displays. The
causes of trouble are displayed by a blinking interval (blinking
code) of these LED's.
The remaining modules are also equipped with status
displays. A blinking of these displays points to a module
error.
