VIII. OPERATION
Thermal Rollback
The Pilot is equipped with a thermal rollback circuit. This circuit monitors the temperature of the motors and the
Pilot. In the event that either one of the motors or the Pilot becomes excessively hot (above 122° F), the Pilot
reduces the motor voltage. For every degree above 122° F, the controller reduces the voltage by 5 volts. This
reduces your power chairs speed and allows the electrical components to cool down. When the temperature
returns to a safe level, your power chair resumes its normal speed.
WARNING! Under strenuous driving conditions, it is possible for the bottom and side case
temperature of the Pilot to exceed 105° F. DO NOT touch the side or bottom of the Pilot
case under these circumstances.
Trouble Codes
In addition to indicating the current state of battery charge, the battery condition meter can also indicate possible
problems with your power chair. The battery condition meter has ten lights. The lights provide information by the
number of lights that are flashing. If any of the meter lights are flashing rapidly, the controller may be indicating a
fault. For instance, if the first light is flashing rapidly, the battery voltage is nearly depleted. The following is a list of
the possible errors signified by the rapidly flashing meter. When you get a trouble code, contact your authorized
Pride provider.
