Thermal Protection; Main Circuit Breaker - Heartway Medical Products S33 User Manual

D. Electromagnetic Brakes:
Your power scooter comes with 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 scooter is ON but in a
steady state (i.e. Wigwag is released to the neutral position), even when the scooter
is on a slope. The Electromagnetic Brakes will also be set whenever the power
scooter 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 18 to make sure brakes are in good condition.
E. Thermal Protection:
Your power scooter controller is equipped with a safety system called thermal
rollback. A built-in circuit monitors the temperature of the controller and motor. In
case of excessive heat of the controller and motor, the controller will reduce the
speed of your power scooter to allow the electrical components to cool down.
Although your power scooter 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 reset button is located on the top of the battery box. (See
Fig 16)
Circuit
Breaker
The main circuit breaker monitors the electric current drawn from the battery. It is
a safety feature built in your power scooter for your extra safety. When the batteries
and motor are heavily strained (e.g., from excessive loads),the main circuit breaker
will trip to prevent damage to the motor and the electronics. If the circuit breaker
trips, turn off the scooter, wait for approximately one minute and then depress the
button to reset it. Then turn on the scooter, and continue normal operation. If the
main circuit breaker continues to trip repeatedly, this indicates a fault so contact
your authorized dealer.
