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 detection field (the assistant). The below example illustrates the test for a backing sensor
application. Use a similar procedure for front, side or multiple radar systems by confirming detection of each
radar sensor in the operator display.
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.
4.
Verify the green “POWER” light is illuminated on the in-cab display.
5.
The area to the side of the vehicle should be clear of obstacles for a distance of 6 meters (20ft). If the
display shows any indicator other than the green light then there are objects to the side of the vehicle that will
interfere with the test. Move the vehicle to a clear area and proceed.
6.
The assistant should move to approximately 2 meters (6ft) to the rear of the sensor in sight of the
operator’s mirrors. He should then walk toward the centerline of the sensor parallel to the vehicle, while the
operator notes when the display detection LED illuminates, signifying the sensor has detected the object.
7.
The assistant should continue walking through the area at the side of the vehicle while the operator
notes the area that detection occurs.
8.
Now face the sensor and walk from the center of the sensor straight back, away from the vehicle. When
the display detection LED quits illuminating the detection limit has been reached.
9.
Move halfway back towards the sensor and remain still for a few seconds, the display detection LED
should stay lit, demonstrating the system’s ability to detect a still object.
10.
The assistant should walk the complete side 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.
