System Operation

SYSTEM OPERATION
When KLI5 is switched "ON", the PDC system is switched "ON", in the standby mode. The system performs a self-check of the ultrasonic sensors and control electronics.




When the transmission is shifted into reverse, the system is activated and the sensors are activated in the pre-determined order.

The system stays active up to approximately 20 MPH. Above this, the system reverts to the standby mode.

If an object is detected within the operating range of the sensors, the control module will activate the respective gong/speaker (front/rear). The sensor closest to the object will receive additional activations to determine if the object is getting closer.




As the distance to the object decreases to approx. 1 1/2 feet, the control module increases the activation frequency of the sensor. The output frequency of the gong will increase linearly up to a distance of approx. 3/4 of a foot. At this time the frequency will change to a constant tone.

As the distance to the object increases, the frequency of the sensor and gong activation decreases until the object is out of the monitoring range of the sensor.
