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.
F.
Main Circuit Breaker:
The main circuit breakers reset button located near the seat of the back side on the
main frame.(Fig 39 ) 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 motor 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 operation. If the main circuit breaker continues to trip repeatedly, contact
your authorized dealer.
