Systems
1. The PreView
tm
system is intended as an Object Detection System and should not be relied upon as your first line of
defense for the safe operation of the vehicle. It should be used in conjunction with established safety programs and
procedures to augment the safe operation of the vehicle, ground personnel, and adjacent property. Should the system
become inoperative, it could jeopardize the safety or lives of those who depend on the system for safety.
2. Testing and inspection of the system in accordance with these instructions and record of the results should be listed on
the daily maintenance report. The units on operating vehicles must be tested each day prior to the vehicle's operation.
Results of this test must be recorded in the maintenance log.
3. People operating this equipment MUST check for proper operation at the beginning of every shift or safety inspection
period.
4. People's lives depend on the proper installation of this product in conformance with these instructions. It is necessary to
read, understand and follow all instructions shipped with the product.
5. Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death.
6. The PreView
tm
Object Detection System is intended for commercial use. Proper installation of a back-up aid requires a
good understanding of truck electrical systems and procedures, along with proficiency in the installation.
7. Store these instructions in a safe place and refer to them when maintaining and/or reinstalling the product.
Testing and Maintenance
NOTE: A walk around test shall be performed every day to verify proper function of the system and to familiarize the operator
with the zone of detection. More frequent inspections should be performed when:
The vehicle is operating in a particularly dirty or harsh environment.
The operator has reason to suspect the system has been damaged.
This test should be performed with two people, one who remains in the cab (the operator), and one who walks through the
sensor field to the rear of the vehicle (the assistant).
1. Clean the sensor face of any accumulation of dirt, mud, snow, ice, or debris.
2. Visually inspect the attached wiring and cable and verify that they are properly secured, not chafing or dangling free
where they could become snagged and damaged. Inspect the Radar Sensor and Operator Display Module and verify that
they are securely attached to the vehicle.
3. Set the park brakes, start the vehicle, depress and hold the vehicle brake and place the vehicle in reverse.
4. Verify the green “POWER” light is illuminated on the in-cab display.
5. The area to the rear of the vehicle should be clear of obstacles for a distance of 8 meters. If the display shows any
indicator other than the green light then there are objects to the rear of the vehicle that will interfere with the test. Move
the vehicle to a clear area and proceed.
6. The assistant should move to just behind the rear corner of the vehicle in sight of the operator's mirrors. He should then
walk toward the centerline of the vehicle parallel to the rear, noting when the external backup alarm activates, signifying
the sensor has detected him. Upon hearing the backup alarm the operator should verify all the display LED’s are lit and
the audible alarm is quickly pulsing. Note: If an external backup alarm is not connected, the operator will notice a
detection only by the display LED’s and buzzer operation and communicate the detection or lack of detection to the
assistant as the assistant moves through the area to the rear of the vehicle.
7. The assistant should continue walking through the area at the rear of the vehicle noting the area that detection occurs.
8. Now walk from the center of the rear of the vehicle straight back, away from the vehicle. When the alarm quits sounding
the detection limit has been reached.
9. Move halfway back and remain still for a few seconds, the alarm should continue to sound, demonstrating the system’s
ability to detect a still object.
10. The assistant should walk the complete rear of the vehicle noting the detection edges of the entire coverage area.
11. After the test the assistant needs to communicate to the operator the details on the detection zone.
