Cat® Detect Object Detection System Caterpillar

Calibrate the Object Detection Sensors

This procedure is used in order to calibrate the object detection sensors. The object detection sensors must be calibrated if any of the conditions that are listed below have occurred:

• Initial installation of the system.

• Any of the object detection sensors were replaced.

• Any of the object detection sensors have been adjusted or the brackets replaced.

This procedure is used in order to validate that the radars for the system have been installed and adjusted correctly. The procedure will utilize an object (pickup truck or light vehicle). The object will be used in order to explore the limits of radar coverage.

This procedure will define the radar mapping coverage for pickup truck or light vehicle size targets. The angles at which the radar brackets are oriented determine the proper coverage area of the radars and avoid ground reflections. Ground reflections caused by improperly positioned radar brackets may cause false detections. Record any instances where the alarm system failed to perform properly, including any nuisance alarms. A case where there might be holes in coverage, such that the target might disappear, should be avoided.

Machine Preparation

Note: Prior to performing this procedure ensure that all components are installed in the appropriate positions as described in the Testing and Adjusting, "Object Detection Sensor - Adjust" section of this manual and adjust the camera angles in order to obtain the best view of coverage areas.

1. Park the machine in a wide open area that is large and level. This area should have 30 m (98.5 ft) of clearance to the front and the rear of the machine. This area should have 10 m (33 ft) of clearance to the sides of the machine. Refer to Illustration 1.

2. Set the parking brake.

3. Turn the disconnect switch to the ON position

4. Start the machine.

5. Verify that the system is powered up and the system status indicator and the system fault indicators are illuminated green on the display.

6. While the machine is parked in the large wide open area check for any surrounding obstacles like bumps, and so on, by observing the display for any flashing areas in the radar detection area. The situations that are listed in Table 2 can cause false targets to be detected and are listed in order of precedence:

   Table 2

   Description of Cause	Resolution
   Test area is not level, area in front or rear of machine has an uphill slope.	Find a test area that is more level or reposition the area of the machine being validated to face the area with the down hill slope to calibrate the system. Do not use an area with too great of slope (2 to 3 percent max) to validate the system.
   The object detection sensor angle is too low and is detecting ground reflections.	The object detection sensor angles provided in the installation information were determined to be the optimum angles for installation, however due to installation variations and differences in machines the actual angle may require adjustment. Refer to Testing and Adjusting, "Object Detection Sensor - Adjust" section of this manual for additional information
   There is mud or some other type of debris blocking the sensor.	This is unlikely to occur unless there is an active event displayed on the display. Clean the object detection sensors to eliminate the issue.

Calibration Procedure

The calibration process consists of a pickup truck (target vehicle) being driven in and out of the object detection sensors coverage area. The operator of the target vehicle will be told to stop via radio whenever the target appears or disappears on the display. This procedure is performed in order to determine the limits of the coverage area and any identify holes that may exist in the coverage area. In the case that the limits of the coverage area are inadequate, adjustments will need to be made to the angles and brackets of the object detection sensors. This procedure will be performed for the following areas of the machine:

• Front

• Rear

• Right Side and Left Side

Front of the Machine

Lay out a line perpendicular to the centerline of the radar. Extend the line 15 m (50 ft). Lay out additional lines parallel to the centerline of the radar. Lay out lines at the following intervals:

• 1 m (3 ft)

• 1.5 m (5 ft)

• 3 m (10 ft)

• 6 m (20 ft)

• 9 m (30 ft)

• 12 m (40 ft)

• 15 m (50 ft)

• 20 m (65 ft)

• 25 m (82 ft)

The object will be moved close to the machine and parallel to the front of the machine and the display is checked for the object detection. The object will then be moved perpendicular to the front of the machine as shown in Illustration 2. The object should start close to the machine for the first pass and work away from the machine with each successive pass. Stop the passes once the object is no longer detected.

Illustration 2	g02729987
Testing the object detection coverage area at the front of the machine

The person in the cab of the machine will inform the person moving the object when to mark the coverage start/stop point. The start/stop points must be marked when the object first appears or first disappears from radar coverage on the display. The designated reference point for the rear radar will be the center of the machine. The distance from the initial perpendicular detection must be measured and should be approximately 2 m (6.6 ft) from the front of the machine. Refer to Illustration 3.

Illustration 3	g02728162

If the detection area is not approximately 20 m (65 ft) long by 24.5 m (80 ft) wide, or the coverage area contains holes, adjust the angles of the brackets for the object detection sensors. Refer to the Testing and Adjusting, "Object Detection Sensor - Adjust" section of this manual for additional information regarding the adjustment of the brackets.

Note: If the detection area is larger than the dimensions listed above, adjustment of the object detection sensors is not required.

Operate the machine to determine if additional adjustment is required.

Rear of the Machine

Lay out a line perpendicular to the centerline of the radar. Extend the line 20 m (65 ft). Lay out additional lines parallel to the centerline of the radar. Lay out lines at the following intervals:

• 1 m (3 ft)

• 1.5 m (5 ft)

• 3 m (10 ft)

• 6 m (20 ft)

• 9 m (30 ft)

• 12 m (40 ft)

• 15 m (50 ft)

• 20 m (65 ft)

The object will be moved close to the machine and parallel to the rear of the machine and the display is checked for the object detection. The object will then be moved perpendicular to the rear of the machine as shown in Illustration 4. The object should start close to the machine for the first pass and work away from the machine with each successive pass. Stop the passes once the object is no longer detected.

If the detection area is to narrow or contains holes in the coverage area the angles of the brackets of the object detection sensors. Refer to the Testing and Adjusting, "Object Detection Sensor - Adjust" section of this manual for additional information regarding the adjustment of the brackets.

Note: If the detection area is larger than the dimensions listed above, adjustment of the object detection sensors is not required.

Operate the machine to determine if additional adjustment is required.

Right Side and Left Side of the Machine

Lay out a line perpendicular to the centerline of the radar. Extend the line 6 m (20 ft). Lay out additional lines parallel to the centerline of the radar. Lay out lines at the following intervals:

• 0.5 m (1.5 ft)

• 1 m (3 ft)

• 1.5 m (5 ft)

• 3 m (10 ft)

• 5 m (16 ft)

The object will be moved close to the machine and parallel to the side of the machine and the display is checked for the object detection. The object will then be moved perpendicular to the rear of the machine as shown in Illustration 6. The object should start close to the machine for the first pass and work away from the machine with each successive pass. Stop the passes once the object is no longer detected.

This pattern will be completed on both sides of the machine. The target should start outside of the detection range of the radar. The target will walk parallel to the machine and stop whenever the target appears in the radar detection area.

Illustration 6	g02728232
