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 equipment 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, the operator who remains in the
cab, and the assistant who walks through the sensor field (detection zone).
1. Move the equipment to an open field larger than the detection zone to test.
2. Clean the sensor face of any accumulation of dirt, mud, snow, ice, or debris.
3. 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 PreView
®
Sensor and Operator Display
and verify that they are securely attached to the equipment.
4. Place the sensor in active mode. Make sure the equipment has been
secured and remains stationary.
5. Verify the sensor is operational. Depending on operator notification, this may
be: green Power LED (for display), green icon (in-cab video monitor), or beep
(buzzer or SAS).
6. Assure the detection zone has been cleared of all obstacles. Any obstacles
in the detection zone will interfere with the test.
7. The assistant should walk (a minimum of 3 mph for Side Defender
®
II)
towards the sensor while the operator notes when the warning activates,
signifying the sensor has detected the assistant and identifying the detection
zone limits.
8. Next, the assistant should walk from the center of the sensor field straight
back, away from the equipment (the center line of the detection zone) while
the operator notes when the warning (notification) stops.
9. The assistant should move a meter to the left of the sensor and walk towards
the sensor again while the operator notes the warning.
10. Repeat the above step by moving out another meter to the left and walking
towards the sensor while the operator notes the warning.
11. Repeat this test sequence for the right side.
12. Finally, after the test, the operator and the assistant need to communicate
the details on the detection zone.
