Elevation Adjustment Procedure
Illustration 19 g06202931
437-4620 Protractor being used with a 533-1164 Angle Bracket to level an object detection sensor.
Note: Markings on the brackets are to be used as reference only. Always make fine adjustments with the 437-4620 Protractor.
Loosen the four adjustment bolts on the bracket for the object detection sensor.
Use a 437-4620 Protractor to set the proper elevation angle or adjust the angle to fine-tune the system.Note: With the machine parked on a level surface the angle will be measured from the horizon to the top of the enclosure. Refer to the angles listed in Testing and Adjusting, UENR1274, Object Detection Sensor - Adjust.
Carefully tighten the four azimuth adjustment bolts on the brackets for the object detection sensors.
Check the angle again to verify that the bracket is set to the proper angle.
Tighten the bolts.
Check the angle again to verify that the bracket is set to the proper angle.
If needed perform the procedure that is located in Testing and Adjusting, UENR1274, Object Detection Sensor - Calibration.Marking the Adjustments

Bracket marked after the installation and adjustment is completed.
After the installation and adjustment is completed, mark the location of the side bolts and washers on the bracket. The mark will allow for quick visual inspection of the system for proper adjustment at maintenance intervals.Expected Results After Adjustment
After the angles and azimuths have been adjusted, and no objects are present in the coverage areas, the system shall produce no visual indicators or audible alarms when the system is active with no faults. If the system produces false detections, utilize the "Status" page in Cat Electronic Technician (Cat ET). Check which radar is falsely detecting objects and the distance at which the faults are detected.
Verify that the coverage areas are clear of objects.
Verify that no part of the machine is in the detection area. (For example, grease lines or third-party attachments.)Note: Due to variance in machine configurations, adjusting the radar azimuth angles in or out as Much as 5 degrees may be necessary. If this adjustment is done to avoid false detections, use the calibration procedure to verify that the system is functioning properly and providing adequate coverage. Any change from the documented angles will change the coverage area.
Verify that the internal enclosure seal is not obstructing the radars viewing angle.Note: Remove, adjust, or replace the cover if the internal enclosure seal is obstructing the view.
Verify that the coverage areas are clear of objects.
Verify that the sensor is not detecting the ground.Note: Due to variance in machine height, adjusting the radar angle upward as much as 5 degrees may be necessary. If this adjustment is done to avoid false ground detections, use the calibration procedure to verify that the system is functioning properly and providing adequate coverage.Note: Any change from the documented angles will change the coverage area.Torque Reference
