Programmable parameters
WARNING
Incorrect configuration settings
Falling, tipping over, collision due to programming errors
f
Programming may only be performed by qualified personnel trained by the manufacturer. The manufacturer of
the product and the control unit manufacturer are not liable in case of damage caused by programming which
was not performed properly and/or which was not adjusted properly according to the user's abilities.
f
Note that modified parameter settings in the configuration can lead to changes in driving characteristics. In
particular, changes to the speed, acceleration, braking or joystick settings can lead to unexpected and there-
fore uncontrollable driving characteristics and cause an accident.
f
Parameters not described in this service manual may not be changed, or only in consultation with Ottobock.
f
After configuration/programming is complete, the user must test the driving characteristics of the product un-
der the supervision of the qualified personnel.
The following description provides an overview of the programmable parameters. Detailed information regarding
programming can be found in the document "VR2 SERIES WHEELCHAIR CONTROL SYSTEM; OPERATION,
INSTALLATION & PROGRAMMING SK77898" from the control unit manufacturer Curtiss-Wright.
Additional parameters which may be accessible with a different version of the programming software may not be
changed or may only be changed following consultation with Ottobock.
6.3.1 General parameters
Parameter
Setting range Description
Sleep timer
1-minute incre-
ments from 0 to
30 min
Setting of time period in which wheelchair is inactive before the control sys-
tem switches off. If the time is set to 0 the system never switches off.
Joystick throw
This allows programming so that full speed can be reached with a slight joy-
stick movement (throw). This is particularly useful for wheelchair drivers with
restricted hand or arm mobility.
Invert joystick
On, Off
Setting this parameter causes the wheelchair to be moved in the opposite
direction to the direction of joystick deflection.
On: if the joystick is moved forward the wheelchair moves backwards.
Off: if the joystick is moved forward the wheelchair moves forward.
Function of the joystick remains unchanged when deflected left or right.
Soft stop rate
Single steps
from 0 to 200
Setting of deceleration value for soft stopping of the wheelchair.
Soft-stopping occurs if the VR2 control is switched off while the wheelchair
is being driven.
Soft reverse
deceleration
Single
steps from
25 to 100%
Setting of the deceleration rate when the wheelchair is stopped whilst moving
backwards. This value can be set separately via the "Deceleration" parame-
ter to prevent the wheelchair from tipping over when being driven backwards
down a slope.
This value is set as a percentage of the "Deceleration" parameter. A typical
value is 70%.
Reverse driving
alarm
On, Off
Sets whether the VR2 control gives an audible warning while driving in re-
verse.
On: an acoustic warning signal sounds.
Off: the alarm is deactivated.
Lock function
enabled
On, Off
The locking sequence can be activated to prevent the wheelchair being dri-
ven by an unauthorised person.
On: the lock function is available.
Off: the lock function is deactivated.
Brake fault
detect
On, Off
Enables detection of defective power brakes or brake connections via the
VR2 control.
On: brake defects are detected.
Off: brake defects remain undetected.
