7.0 The VR2 Hand Control Series
7.1 VR2
On/off button:
The on/off button applies power to the control system electronics,
which in turn supply power to the wheelchairs motors. Do not use the
on/off button to stop the wheelchair unless there is an emergency. (If
you do you may shorten the life of the wheelchair drive components)
Battery gauge:
The battery gauge shows you that the wheelchair is switched on. It
also indicates the status of the wheelchair. Refer to chapter 8.
Locking/unlocking the wheelchair:
The VR2 control system can be locked to prevent unauthorised use.
The locking method is via a sequence of key presses and joystick
movements as detailed below.
To lock the wheelchair
•
While the control system is switched on, depress and hold the on/
off button
•
After 1 second the control system will beep. Now release the on/
off button
•
Deflect the joystick forwards until the control system beeps
•
Deflect the joystick in reverse until the control system beeps
•
Release the joystick, there will be a long beep
•
The wheelchair is now locked
To unlock the wheelchair
•
Use the on/off button to switch the control system on. The
maximum speed/profile indicator will be rippling up and down
•
Deflect the joystick forwards until the control system beeps
•
Deflect the joystick in reverse until the control system beeps
•
Release the joystick, there will be a long beep
•
The wheelchair is now unlocked
Operating the control joystick:
When engaging the main On/Off button, allow a few seconds prior
to moving the joystick. This allows the system to self check. If you
move the joystick too soon, the battery level indicator display will not
illuminate until the joystick is released.
If it is off null for more than 5 seconds a system error will occur.
Whilst this is not harmful to your wheelchair, you will need to switch
off and then back on to clear the system.
Note: This is a safety feature to prevent unintended movement.
Proportional control summary
1.
To steer, move the joystick in the direction you wish to go.
2.
The further you move the joystick, the faster you will go.
3.
New users should use slower speeds until they feel confident
when driving the wheelchair.
4.
The brakes will automatically stop the wheelchair from any speed
when the joystick is released.
5.
It is important that the chair is stationary when changing direction
from reverse to forward.
6.
Always switch off before getting into or out of the chair.
Maximum speed/profile indicator:
This is a gauge which shows the maximum speed setting for the
wheelchair or if the control system is programmed for drive profile
operation, the selected drive profile. This gauge also indicates if the
speed of the wheelchair is being limited or if the control system is
locked.
The horn button:
The horn will sound while this button is depressed.

Speed / Profile decrease button:
This button decreases the maximum speed setting or, if the control
system is programmed for drive profile operation, selects a lower
drive profile.
Speed / Profile increase button:
This button increases the maximum speed setting or, if the control
system is programmed for drive profile operation, selects a higher
drive profile.
Actuator button and LEDs:
Depending on whether your wheelchair is fitted with one or two
actuators the operation of these buttons will differ.
Wheelchairs with one actuator
Depressing either actuator button will enter actuator adjustment
mode. This will be indicated by the illumination of both actuator
LED's. Actuator adjustment can then be made by deflecting the
joystick forwards or backwards. To re enter drive mode, depress
either actuator button
Wheelchairs with two actuators
Depressing either actuator button will enter actuator adjustment
mode. If the left button is depressed the associated LED will be
illuminated, and deflection of the joystick will adjust the actuator
motor connected to that channel. If the right button is depressed the
associated LED will be illuminated, and deflection of the joystick
will adjust the actuator motor connected to the other channel.
To re enter drive mode, depress the selected actuator button, as
indicated by the associated LED
It is also possible to select the other actuator by left or right movements
of the joystick
Charging and programming socket:
This socket should only be used for programming and charging the
wheelchair. This socket should not be used as a power supply for any
other device. Connection of other electrical devices may damage the
control system or affect the EMC performance of the wheelchair
See section 11 about charging.
The programming socket will enable an approved Sunrise Medical
authorised dealer to re-programme your chair and also gain useful
information when tracing any faults. When the chair leaves the
factory, the parameters of the controller are set to default.
To programme the controller you need a special programming device
(handheld or PC software), which is available through your Sunrise
Medical authorised dealer.
WARNING - Programming the controller of the wheelchair is only
allowed through authorised personnel trained by Sunrise Medical.
Incorrect controller settings could cause driving outside the safe limits
and could result in damage or injury.
Note: SUNRISE MEDICAL does not accept responsibility for
damages which result from unexpected stopping of the wheelchair or
inappropriate programming or unauthorised use of the wheelchair.
