POWER MODULES
The power module < R-Net >[1] resp. VR2 [2] stores
the settings of the driving parameters and adopts
as the power electronic the addressing of the drive
motor respectively on two motor wheelchairs the
addressing of both drive motors.
The inlets and outlets of the power module are 1
short circuit proof, so that the lead fuse is not ap-
plicable.

45
Programming the driving behav-
iour

The driving behaviour of the electronic ve-

hicle can, vehicle dependently be adjusted
through a programming device.
The parameter values of the delivery con-
figuration are selected in such a fashion
that the requirements of the EG-directive
93/42 (CE-marks) are fulfilled. Programming
that differs from these requirements might
not fulfil the regulations.

The driving behaviour of the wheelchair

should be adjusted to the individual re-
quirements and the learning process of the
respective user at regular intervals.
In doing so the driving experience, the phys-
ical limits of the user and the main field of
operation must be considered:
☞ When programming the delay value ob-
serve that on one hand extreme brak-
ing can endanger the driver, on the
other hand the braking distance must
correspond to the maximum values of EN
12184 (view chapter Braking distance on
page 70).
☞ The programming must be specially tai-
lored to the user. The capacity of reac-
tion, the constitution as well as physical
and psychical abilities are to be consid-
ered. A talk with the doctor or therapist
can be very helpful.
☞ An adjustment to the manufacturer set-
tings of the driving parameters changes
the optimal driving behaviour of the ve-
hicle.

Independent of this the safety of the wheel-

chair and especially the driver must be guar-
anteed after a change of the parameters.
☞ All changes to the parameters underlie
solely the responsibility of the person
making the modifications.
☞ Parameters can accidentally be adjusted
to settings that cannot generally exempt
hazards.
