Drive Profile Selection
Your Microdrive controller may be programmed for more than one drive profile that allows the system to be custom tailored to your environment.
To select a profile setting:
1.Use the on/off switch to power on the chair and the controller.
2.Press the mode button.
3.Move the joystick left or right to select the desired drive profile. Each of the LEDs indicate a separate profile.
NOTE: The system can be programmed with 5 different profiles.
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 adjustment dial clockwise.
3.To decrease your speed, turn the speed adjustment dial counterclockwise.
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.
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.
