The controller

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 or 3 contact your dealer.

2. VR2 Lights
   

3. VR2 Seats&Lights
   

VR2 by PG Driving Technologies is a collective name for the entire control system of the wheelchair. The wheelchair is operated by means of a controller, which includes the following components:

Driving the wheelchair with the controller

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 4).

Driving the wheelchair

Driving an electric wheelchair is done by operating a joystick. Move the joystick forwards and the wheelchair will also move forwards. Steer left and right and the wheelchair will turn.

Speed

The maximum speed can be controlled by the speed regulator on the controller (F1 en F2 in figure 4). The maximum speed is displayed by the LED lights above the speed regulators (D2 figure 4). Speed can be controlled with the joystick while driving. If the joystick is moved a little, the wheelchair will move more slowly

Operating 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:
Figure 5 Electrical adjustment options

• Tilt adjustments
• High/low adjustments
• Backrest adjustments
• Legrest adjustments

To use electrical adjustment options, the VR2 Seats&Lights controller is required (maximum of two options).

Selecting the desired adjustment option

1. Switch on the controller

2. Press on the ‘mode’ button (E in figure 4) to select the ‘adjustment options’ mode. The controller will now be in the ‘adjustment options’ mode. It is also possible to follow the status.
   The joystick is used to select and operate the electronic adjustment options.

3. Move the joystick to the left or the right to select the desired adjustment option. The selected adjustment option will be visible on the display screen.

4. Moving the joystick forwards and/or backwards will activate the selected electronic adjustment option (see table 6). Move the joystick forwards or backwards until the desired adjustment option has been attained.
   Table 1 Electrical adjustments| Move joystick backwards| Move joystick forwards
   ---|---|---
   Tilt adjustment| The entire chair will tilt backwards| The entire chair will tilt forwards
   High/low adjustments| The entire chair will be raised| The entire chair will be lowered
   Backrest adjustments| The backrest will tilt backwards| The backrest will tilt forwards
   Legrest adjustments| The legrest angle will increase, the footplate will be raised| The legrest angle will decrease, the footplate will be lowered

5. To return to the ‘drive’ mode: Press on the ‘mode’ button to select the ‘drive’ mode

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 due to safety reasons.

Lights

Not every wheelchair has been equipped with lights. You can activate the following functions only by using VR2 Lights and/or VR2 Seat&Lights:

• Lights (I in figure 4)
• Hazard Lights (J in figure 4)
• Direction indicators (K1 & K2 in figure 4)

Troubleshooting (Fig. 6)

If the wheelchair will not function while the batteries are fully charged, check the following points before consulting your dealer:

• Switch the controller off and then switch it on again. Check to see if the malfunction has been solved.
• Check if the free wheel switch was switched to Drive.
• Check if the joystick was in the 0 position when the controller was switched on. In other words, the joystick must not be moved when the controller is being switched on or off.

Malfunctions list
An extended malfunction list can be found in the appendix of the service manual (for qualified specialists only). The service manual can be found on www.SunriseMedical.eu
