Section 2 Understanding Controller Display 2.1 The Maximum Speed Indicator Ripples The wheelchair is locked. To unlock the wheelchair, deflect the joystick forwards until the control system chirps. Then deflect the joystick in reverse until the control system chirps. Release the joystick, there will be a long beep. The wheelchair is now unlocked. 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 chirp. Now release the on/off button, deflect the joystick forwards until the control system chirps, and deflect the joystick in reverse until the control system chirps. Release the joystick, there will be a long beep. The wheelchair is now locked. 2.2 The Maximum Speed Indicator Flashes This indicates that the chair is charging via on-board charger. The chair will be ready to drive as soon as the charger is unplugged. 2.3 Battery Gauge is Steady This indicates that all is well. 2.4 Battery Gauge Flashes Slowly The control system is functioning correctly, but you should charge the battery as soon as possible. 2.5 Battery Gauge Steps Up. the wheelchair batteries are being charged with the offboard charger. You will not be able to drive the wheelchair until the charger is disconnected and you have reset the control system by switching off the power and then powering up again. 2.6 Battery Gauge Blinks Once Every 2.5 Seconds The control system has "gone to sleep" because the wheelchair has not been driven for a period of time. The time period depends on the programming of the system. To re-start, reset the system by switching off the power and then powering up again. 2.7 Battery Gauge Flashes Rapidly (even with the joystick released) The control system safety circuits have been activated and the control system hasbeen prevented from moving the wheelchair. This indicates a system trip, i.e. the VSI has detected a problem somewhere in the wheelchair's electrical system. Please refer to Section 3 (VSI Controller Diagnostics).

3.1 One Bar - Low Battery Voltage Section 3 Understanding VSI Controller Diagnostics Codes This code could indicate discharged batteries, failed batteries, or poor battery connections. Begin by recharging the batteries and then refer to Section 1 to check batteries and connections. 3.2 Two Bars - Left Motor Disconnected The left hand motor has a bad connection. Check the connections to the left hand motor. Test Left Motor Open Check that the batteries are fully charged and in good condition; and check all cables and connections. Check the connections to the left motor, look for a loose or damaged connector. Remove the 9-pin Beau plug and check the resistance across pin 3 and pin 4 as shown in (figure A3.2.1). If the meter reads between 0 to 1.5 ohms, then replace the controller. 1 3 5 7 2 4 6 8 9 A3.2.1 1000 OFF V DC 200 20 2000m 200m 20M 2000K 200K 20K 2000 200 OHM 750 200V AC V mA COM 10A 200u 2000u 20m 200m 10A A DC DIGITAL MULTIMETER If the meter reads between 0 to 1.5 ohms, then replace the controller. Otherwise, check both brushes on the left motor. (Refer to Section 4 Step 9 of this Service Manual for easiest access). Ensure that the brushes are not excessively worn, (replace as required). Top access for Motor brush shown in (figure A3.2.2)(requires shroud removal). A3.2.2 Use the meter to check the resistance across the two bottom contacts (thicker wires) on the 4-pin motor connector as shown in (figure A3.2.3). If the meter reads between 0 to 1.5 ohms, then replace the main harness. If none of the above corrects the problem, replace the left motor.
