1. Electromagnetic Brakes Your power wheelchair comes with an Electromagnetic Brakes 1 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 wheelchair is ON but in a steady state 1 e Joystick 1s 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 See Fig 39 Note Please refer to the section titled to check brakes in the Maintenance amp Repair section in page 22 to make sure brakes are in good condition E Thermal Protection Your power wheelchair controller 1s 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 1f you find that you have lost speed suddenly Main Circuit Breaker The main circuit breaker reset button 1s located near the seat of the back side on the mainframe Fig 39 The main circuit breaker monitors the electric curre2. The farther away to the front back the joystick is pointing the tilt angle of the seat of the vehicle will be To operate the vehicle by pushing gently the joystick in the direction you want to go Returning the joystick to its neutral position center will reduce the speed and stop the vehicle by automatically applying the electromagnetic brakes Notes After pressing the controller ON OFF switch allows two seconds to elapse before engaging the joystick This is a safety feature to prevent sudden start Gentle operation of the joystick will result in smoother transitions in speed and direction while sharp operation of the joystick will result in drastic transitions in direction and velocity n case of emergency let go of the joystick and the chair will come to a stop There is a safety design called inhibit switch device in the vehicle The drive power will be off automatically when the user sits on the vehicle and uses the tilt function exceed a certain angle Warning The tilt angle adjustment range is from 0 to 45 for your vehicle Never stop tilting if you keep far way the joystick until to the maximum degree Only adjust the comfortable angle when you use tilt function then stop for safety B Controller Display The controller display 1s a multifunction visual display It can provide five types of information 1 ON OFF status 2 battery condition meter 3 Horn 4 acceleration 5 deceleration buttons 6 tilt functi
