The TCT system is not a substitute for the service brake which should be used to control speed
and reduce possibility of injury.
If all of the following events occur with the switch in ‘RUN’ position.
a) the vehicle is being driven down a slope.
b) the vehicle speed exceeds the designed speed with the accelerator pedal depressed or released.
the regenerative braking will limit the speed of the vehicle to the designed speed range.When the regenerative brak-
ing feature is activated by this sequence of events, the motor generates power which is returned d to the batteries.
TCT models are equipped with a regenerative motor control system.
The motor’s speed is sensed and regulated directly by the controller. As a vehicle begins to accelerate while
descending a hill, the speed sensor will cause the motor to electrically resist the speed of the vehicle through regen-
erative braking.
If the operator attempts to override the electronic braking feature by moving the direction selector or key switch to
another position, the warning beeper will sound and the vehicle will brake rapidly until it reaches the speed of
approximately 2 mph (3 kph).
The TCT system also incorporates an anti-stall protection feature that prevents commutator damage from stalling the
vehicle against an obstacle or ascending a hill. The electrical power to the motor will be deactivated allowing the
vehicle to roll freely before damage can be done.
In Performance Mode option features different degrees of regenerative breaking that takes place anytime that accel-
erator pedal is released. The Steep Hill option will rapidly slow the vehicle to a stop unless the accelerator pedal is
depressed. The Mild Hill option will slow the vehicle to a stop at a slower rate unless the accelerator pedal is
depressed.
The TCT has a low power consumption unit but it will drain the vehicle batteries over a period of time. If the vehicle is
to be stored for a prolonged period of time, the TCT should be disconnected from the batteries by selecting the
‘TOW/MAINTENANCE/STORAGE’ position on the Run-Tow/Maintenance/Storage switch located under the passen-
ger seat.
The Electronic Speed Control system consists of three separate units; a pedal box, speed sensor, and controller.
Regenerative Braking
To prevent the possibility of loss of control that could cause severe injury or death, use service
brake to control speed. The TruCourse technology system is not a substitute for the service
brake.
TruCourse Technology vehicles are equipped with a regenerative motor control system.
Example: If all of the following events occur...
a) the vehicle is being driven down a slope
b) the vehicle attempts to exceed the specified top speed with the accelerator pedal depressed or released
the regenerative braking will limit the speed of the vehicle to the specified top speed (the warning beeper will not
sound). When the regenerative braking system is activated by this sequence of events, the motor generates power
which is returned to the batteries.
If the operator attempts to override the regenerative braking feature by moving the direction selector or key switch to
another position, the warning beeper will sound and the vehicle will brake rapidly until it reaches the speed of
approximately 2 mph (3 kph).
