D.
Electromagnetic Brakes:
Your power wheelchair comes with an Electromagnetic Brakes., i.e. an automatic magnetic disc
safety brake which is also known as Fail-Safe brake.
The Electromagnetic Brakes are automatic and work when the power wheelchairs is ON but in a
steady state (i.e. Joystick is released to the neutral position), even when the chair is on a slope.
The Electromagnetic Brakes will also be set when-
ever the power wheelchair is OFF, but the motor levers are in the engaged (vertical) position.
Note: Please refer to the section titled to check brake in the Maintenance & Repair section in page 17
to make sure brakes are in good condition.
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, 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.
