Error Codes
In addition to indicating the current state of battery charge, the battery condition meter can also indicate possible problems
with your power chair’s electrical system. If any of the battery condition meter lights are flashing rapidly, the controller may be
indicating an error. Error codes are displayed as a number of flashing lights. For instance, if the first light is flashing rapidly, the
battery voltage is nearly depleted. The following table identifies the individual error codes, probable causes, and possible
solutions. If you get one of these error codes, contact your Quantum Rehab Specialist.
Speed Adjustment
The Microdrive controller provides a speed control knob to control the speed of the power chair.
To change the speed:
1. Use the on/off switch to power on the chair and the controller.
2. To increase your speed, turn the speed control knob clockwise.
3. To decrease your speed, turn the speed control knob counterclockwise.
NOTE: The first few times you use your power chair, we recommend you set your speed to the slowest setting
until you become familiar with your power chair.
Sleep Mode
The Microdrive controller offers a sleep mode feature which will shut off the main power if the joystick remains stationary
for a period of five minutes. The battery condition meter will indicate sleep mode by blinking once every five seconds. To
restore power and resume operation of the chair, flip the on/off switch twice.
Thermal Rollback
The Microdrive controller is equipped with a thermal rollback circuit which monitors the temperature of the chair’s motors
and controller. If either exceeds 122° F, the controller reduces the motor voltage by 5 volts for every degree over. This
reduces the chair’s speed and allows a cool down period. Once the temperature returns to a safe level, the chair will
resume normal operation.
