2.1 VR2 controller
A controller will usually have three basic
functions:
• Driving and steering a wheelchair
• Operating electrical seat adjustments
• Charging the wheelchairs batteries
There are many different control systems for
wheelchairs on the market. If the controller on
your wheelchair does not resemble the one in
figure 1, 2, 3 or 4 contact your dealer.
1. VR2 Drive only
2. VR2 Lights
3. VR2 Seats&Lights
4. VR2 Attendant steering
VR2 by PG Drives Technologies is a collective
name for the entire control system of the
wheelchair. The wheelchair is operated by
means of a controller. Main components of the
controller can be found in chapter 2.3.
2.2 VR2 attendant steering
It is possible to connect an extra controller
(figure 4) on the back. This so the attendant can
control the wheelchair and operate electrical
options.

3.1 Switching the controller on or
off
To be able to drive or operate the electronic
adjustment options of the wheelchair, the
controller must be switched on. Press the on/off
button (B in figure 5).
Note!
The joystick should be released (neutral
position) when switching on the controller
otherwise there will be an error code
If the attendant steering needs to be activated,
the user/attendant switch needs to be pressed
(L in figure 5).
3.2 Driving the wheelchair
Driving an electric wheelchair is done by
operating a joystick.
Joystick mounted on armrest or as
attendant control mounted on the push
handle
Move the joystick forwards and the wheelchair
will also move forwards. Steer left and right and
the wheelchair will turn.
Joystick mounted in the Z-steering
mechanism
To operate the controller in the Z-steering
mechanism the push handles needs to be
squeezed to the metal bar below. The chair will
drive in the forward direction. When moving the
bars to the left, the chair will turn right and when
moving them right, the chair will turn left. Lift the
push handles if you want to drive backwards.
3.3 Adjusting the push bar height
The height of the push bar with the Z-steering
mechanism is adjustable in 6 steps and can
easily be set. Pull A (figure 6) and set the height
by releasing the strap on the desired height.
You should hear a click when setting the push
bar height. This indicates that the bar has
locked into place. It is also possible to flip down
the total Z-steering.

Driving the wheelchair 11VR2
3.4 Speed
The maximum speed can be controlled by the
speed regulator on the controller (F1 en F2 in
figure 5). The maximum speed is displayed
by the LED lights above the speed regulators.
Speed can be controlled with the joystick while
driving. If the joystick is moved a little, the
wheelchair will move more slowly.

4 The electrical adjustment
options
Not every wheelchair has been equipped with
electronic adjustment options. We make a
distinction between four different adjustment
options to the seating system:
• Tilt adjustments
• High/low adjustments
• Backrest adjustments
• Legrest adjustments
Note
If you adjust the seat height by using the
high/low option or use the electrical tilt
adjustment 0 - 45°, the speed will be reduced
for your safety.
To use electrical adjustment options, the VR2
Seats&Lights controller is required (maximum
of two options).
4.1 Selecting and operating the
electrical adjustment option
1. Switch on the controller (A in figure 8)
2. To activate the attendant steering the user/
attendant switch needs to be pressed (A in
figure 9 + 10)
3. Press on the ‘mode’ button (B) to select the
‘adjustment options’ mode. The controller
will now be in the ‘adjustment options’ mode.
It is possible to follow the status on the
actuator.
The joystick or the push handles (C) are used
to select and operate the electronic adjustment
options.
4. Move the joystick / handles to the left or the
right to select the desired adjustment option.
The actuator LED’s indicates the currently
selected seating function.
5. Moving the joystick forwards / backwards
or the handles up / down will activate the
selected electric adjustment option (see
table on next page). Move the joystick /
handles until the desired adjustment option
has been attained.

The controller’s standard configuration includes a ‘3-pin connection’. Ensure that the battery charger
is properly connected so that the ‘negative pole’ and the ‘inhibit’ are connected, enabling the system to
prevent the wheelchair from moving when the battery is being charged.
