Electronics Tray

The electronics tray is located on the back of the power base. See figures 6 and 7. The ammeter, the optional onboard charger, the charger power cord receptacle, the main circuit breaker, the controller connector, and the charger fuse are all located on the electronics tray.

Ammeter: The ammeter displays the charger’s current output in amps. See VI. “Batteries and Charging.”

Charger Power Cord Receptacle (with optional onboard charger): This is where the charger power cord plugs into

the power base.

Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair. When the batteries and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker trips to prevent damage to the motors and the electronics. If the circuit trips, allow your power chair to “rest” for approximately one minute. Next, push in the circuit breaker button, turn on the controller, and continue normal operation. If the main circuit breaker continues to trip repeatedly, contact your Quantum Rehab Specialist.

Controller Connector: This is where the controller connects to the power base.

Charger Fuse (with optional onboard charger): The charger fuse protects the ammeter from current overload. There are three fuses on the utility tray. The top one is the charger fuse. The bottom two are spares.

Charger Inhibit Connector: The VSI controller is equipped with a charger inhibit connector. The charger inhibit enables the onboard charger to disable the controller during charging. The charger inhibit connector is coded with colored dots. The dots are positioned so that you can align the flat side of the male connector with the flat side of the female connector before making the connection.

WARNING! Failure to properly align the connectors can result in damage to the controller, the charger harness, and the connectors.

Active-Trac Suspension

The Quantum 1121 is equipped with Active-Trac Suspension (ATS). ATS is a suspension system designed to make your power chair traverse different types of terrain and obstacles while maintaining smooth operation. With ATS, the front anti- tip wheels work in conjunction with the motor suspension to help you maneuver over obstacles in excess of three inches in height.

As the front anti-tip wheels come in contact with an obstacle, the front anti-tip wheel assembly is drawn upward. At the same time, the motors are forced downward. This allows the motors to push the your power chair over an obstacle without the possibility of becoming “hung up” on the obstacle.

ATS also helps in day-to-day operating conditions. For instance, when you release the joystick, your power chair begins to slow down. As the chair slows down, the front anti-tip wheels will automatically drop toward the ground. This will reduce the forward tip that is typically encountered with center-wheel drive chairs.
