8 VR 2 wheelchair control – Installation and programming

8.1 Overview

The VR2 control offers the possibility of showing causes of error messages on the display.
Root causes of faults in the drive and in the power options are identified through flashing LEDs
of the control unit (see section 7.2).
Changes in parameters can be made with the hand-held programming device or via a PC soft-
ware/interface cable (each of which can be ordered separately).
