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 Electro-
magnetic 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 brakes in the Maintenance & Repair
section in page 23 to make sure brakes are in good condition.

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.
E.
Main Circuit Breaker:
Please see Fig 40 to check the circuit breaker location in P16RTL.
(Fig 40)
The main circuit breaker monitors the electric current drawn from the battery. It is
a safety feature built in your power wheelchair for your extra safety. When the
batteries and 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 depress the
button to reset it. Then turn on the controller power, and continue normal opera-
tion. If the main circuit breaker continues to trip repeatedly, contact your
authorized dealer.
