Thermal Rollback - Pride Mobility Jet 12 Owner's Manual

TROUBLE CODES
In addition to indicating the current state of battery charge, the battery condition meter can also indicate
possible problems with your Jet 12. If the battery condition meter is flashing rapidly, the controller may be
indicating a fault.
The following is a list of the possible errors signified by the rapidly flashing meter.
Flash Code
Sequence Diagnosis
Low battery voltage fault.
•—•—•—
High battery voltage fault.
••—••—••—
Left motor (or connection) fault.
•••—•••—
Right motor (or connection) fault.
••••—••••—
Left or right park brake (or connection) fault.
•••••—•••••—
Controller fault.
••••••—••••••—
Motor stalled or joystick out of neutral time out. Reset the power on/off button.
•••••••—•••••••—
The symbol “•” means all 6 LEDs flash on for a period of 0.2 seconds and off for 0.8 seconds.
The symbol “—” means all 6 LEDs are off for a period of two seconds before flashing sequence repeats.
NOTE: You must turn the controller off and then on again to reset the controller, even if the source of the
fault is removed/corrected.
In the event of a fault, the flashing battery condition meter displays diagnostic indications. Faults are
encoded as follows: one (for a low battery voltage fault) to seven (for a motor stalled or joystick out of
neutral time out fault) and displayed by flashing all LEDs the number of times prescribed by the fault code.
The flash sequence (one to seven) is followed by a long off period (2 seconds). If more than one fault exists,
then the fault having the highest priority is indicated. The controller must be turned off and then on again
even if the source of the fault is removed. If you cannot resolve the problem, contact your authorized Pride
provider.

THERMAL ROLLBACK

The Jet 12 controller is equipped with a thermal rollback circuit. This circuit monitors the temperature of
the motors and the controller. In the event that the motors or the controller become excessively hot (above
122° F), the controller reduces the motor voltage. For every degree above 122° F, the controller reduces the
voltage by 5 volts. This reduces your Jet’s speed and allows the electrical components to cool down. When
the temperature returns to a safe level, your Jet 12 resumes its normal speed capability.
