km/h). If the walk away braking function remains engaged for two seconds or more, a warning buzzer will sound to
alert the driver that motor braking has been activated.
WARNING
• Walk Away Braking will not limit vehicle speed to 3 mph (4.8 km/h) on very steep grades. Do not
operate vehicle on slopes exceeding 20% grades.
• Motor Braking: When going down an incline with the accelerator pedal partially pressed, the motor braking function
will activate to assist the operator in maintaining a speed less than the speed setting. For example, if the vehicle is
going down an incline with the accelerator pedal pressed half way, the motor braking function will activate to assist
the operator in maintaining a speed approximately half of the speed setting defined in the Program Menu.
• Regenerative Braking : When motor braking is activated, the vehicle motor acts as a generator, slowing the vehicle
as it creates energy that is used to charge the batteries.
• Run/Tow Switch: When the Run/Tow switch is in the RUN position, the vehicle will function normally. When the
switch is in the TOW position, power to the controller is shut off, disabling the vehicle operating circuit and walk
away braking, allowing the vehicle to be towed.
• Motor Protection Circuit: The operator should never attempt to hold the vehicle on an incline by pressing the
accelerator pedal instead of the brake pedal, as motor overheating could result. By reducing the current to the
motor during such an occurrence, the motor protection circuit reduces the possibility of motor damage. When this
situation arises, a
motor stall fault is recorded by the speed controller and will be displayed on a CDT handset in
the Diagnostic History menu. Motor Stall .
• High Pedal Detect: This function prevents unexpected vehicle movement if the key switch is turned ON after the
accelerator is pressed. The vehicle will not move until the accelerator is released and pressed again. When this
situation arises, a
HPD fault is recorded by the speed controller and will be displayed on a CDT handset in the
Diagnostic History menu. HPD .
