NOTE– Program settings that are not matched for the capabilities of the rider can result in serious injury. Do not alter settings without the advice of your health care professional.

C. THERMAL ROLL-BACK

Your chair has a thermal roll-back circuit. This protects the controller from damage due to overheating. In extreme conditions (such as repetitive hill climbing) the circuit will decrease the power to your motors. This allows the chair to operate at a reduced speed. When the controller cools, the chair will return to normal speed.

D.CIRCUIT BREAKERS

1. Notes:

Your Quickie Z-500 has two battery boxes, with a circuit breaker on each box.

In the unlikely event of a short circuit or heavy overload, all power to your chair will be shut off.

To reset your chair, depress the circuit breaker button(s) on the front of the battery boxes. A few minutes wait is required before the circuit breaker(s) will reset.

2.Repeated Shutdown

If the chair continues to shut down after resetting, have it serviced by a supplier.

E. JOYSTICK ASSEMBLY

The joystick connects to a controller, which controls the chair’s performance. The joystick assembly consists of the following parts:

1. Speed Control Knob (A)

Use the speed control knob to adjust the maximum speed of your chair. Turn it counter-clockwise to reduce speed; turn it clockwise to increase speed.

2.Battery Charge Indicator (B)

Green lights indicate that batteries are fully charged.

Yellow lights indicate that batteries need recharging.

When the lights stay in the red band, the batteries must be recharged.

3. On/Off switch (D)

The on/off/mode switch is located on the rear face of the joystick housing. It is a tog- gle switch. Turning the chair on or off is accomplished by pressing the switch down- ward. The switch will automatically return to the center point. Alternate locations exist for this switch. Please see your supplier in the event that you wish to relocate or re-orient this switch.

4. Mode Switch (D)

The on/off/mode switch allows you to select from 5 (five) different programmable drive profiles or actuator mode sets.

Push up the on/off/mode select toggle switch to index among the five drive and actuator modes. The selected mode indicator will flash.

Push joystick either left or right to select one of the five drive profiles. To select the actuator modes, push the mode select switch twice.

The drive profiles are indicated by the mode indicators (G) and the actuators are indicated by the four actuator lights (H).

To exit drive or actuator mode select, simply push the on/off/mode toggle up one or more times until the indicator no longer flashes, or push the joystick for- ward or reverse to begin driving.

5.JOYSTICK (E)

The joystick controls the direction and speed of your chair. Turn the chair on and move the joystick in the direction you want to go.

Moving the joystick from the neutral (center) position disengages the motor locks, allowing the chair to move.

The chair will move faster the more you move the joystick away from neutral. NOTE– If your speed becomes hard to manage, release the joystick and the chair

will come to a complete stop.

When you release the joystick it will return to neutral; the chair will slow to a stop and the motor locks will reengage.

We recommend that you switch the chair off if you stop for any length of time. This will conserve battery power.

NOTE– Once the chair stops, switching the chair off will not affect the motor locks.

6. Joystick Boot (F)

Make sure the boot is not torn or cracked (this could allow debris, water or moisture to enter). If the boot is torn or cracked, replace it as soon as you can.

7. Remote Switch Jacks (optional) (I)

Two 1/8" mono jacks are optional to provide remote switch control of the on/off power function and the mode select function. Any of the single switches offered by Sunrise Medical can be used to connect to either or both of these jacks (except the single zero touch switch).
