OPERATION

E. Thermal Protection:

Your power wheelchair controller is equipped with a safety system called thermal rollback. A built-in circuit monitors the temperature of the controller and motors. In case of excessive heating of the controller and motors, the controller reduces the motor voltage and speed of the power wheelchair. The reduction of the speed allows the electrical components to cool down. Although your power wheelchair will resume its normal speed when the temperature returns to a safe level, we recommend that you turn the power off and wait for 5 minutes before restarting to allow the components to cool down if you find that you have lost speed suddenly.

F. Main Circuit Breaker:

The main circuit breaker is a reset button located on the front battery box with 2 connectors (Fig. 16). The main circuit breaker monitors the electric current drawn from the batteries. It is a safety feature built in your power wheelchair for your extra safety. When the batteries and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker will trip to prevent damage to the motors and the electronics. If the circuit breaker trips, wait for approximately one minute and then press the button to reset it. Then turn on the controller power, and continue normal operation. If the main circuit breaker continues to trip repeatedly, contact your authorized dealer.

G. Chair Response:

Should the chair’s response not be to your satisfaction, ask your dealer to adjust the program to a level at which you are comfortable. The program can be altered to either increase or decrease the response rates for better control of your power wheelchair.
