Note: Refer to your local Cat dealer for information on installation and adjustment of the cameras and object detection sensors.

System Information

Note: Functioning of this system is not required for this machine to be safely operated. The operator can still use the other means. Use the following examples to verify that the area is clear or provide warning before the machine is moved: direct vision (from cab and ground), mirrors, spotters and warning horns.

Note: The Object Detection System is designed to enhance the operators awareness of the operators surroundings. Use of this system does not replace basic safety precautions and procedures for operating the machine. Refer to the Operation and Maintenance Manual of the machine for additional information.

The Object Detection System uses radar and video to provide the operator with additional information about the work area around the machine. The display interfaces with the radar sensors that are mounted around the machine. The system will detect objects as small as a light vehicle that is in the path of the machine.

Recognition of an object is dependent upon the material composition and the geometry of the object. The system may detect an object that is smaller than a light vehicle. Due to the limited number mounting areas for the object detection sensors on the machine, there are gaps in the radar coverage. These gaps would allow the system to miss smaller objects.

Illustration 2 below shows the coverage that is provided by the radar sensors.

Objects are most likely to enter the blind spots of the machine when the machine has been stopped. To help prevent objects from entering a blind spot unnoticed, the Object Detection System activates when the key switch is turned to the ON position. The system remains in the active state until the machine transitions from a stopped state. The system remains in the active state anytime the machine is traveling in reverse. The system will return to the active state automatically after the operator has brought the machine to a complete stop and has remained stopped for the reactivation delay time that has been configured, or changes the gear of the machine. The reactivation delay is used to stop the system from transitioning from the standby state to the active state while making short stops.

Identify the object and the location of the object before you move the machine. Failure to identify the object and the location of the object prior to moving the machine can result in product damage, personal injury, or death.

Note: Radar information will not be used in order to determine the exact position of the object. Only the general area of the object relative to the machine will be displayed. The operator must use the camera for the designated machine quadrant in order to determine if the object is in the path of the machine and if evasive action is required.

Any critical zone indication will trigger an audible alarm if either of the following conditions are true:

The operator places the machine in gear and attempts to move in the direction of a detected object. For front and rear critical zones only.
The operator places the machine in gear and attempts to move in any direction. For left and right side critical zones only.

Do not operate or work on this machine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility.

Effects on System Operation

The operation of the system can be affected by any of the following factors.

Show/hide table

Personal injury or death could result without observing the following information.

Environmental conditions, installation, and topographical factors can effect the proper operation of the Cat Integrated Object Detection System. The following information must be taken into consideration.

Environmental - Weather conditions may cause mud to build up on the face of the object detection sensor. The moisture that is in the mud can reduce radar coverage by absorbing the RF energy emitted by the object detection sensors. If an accumulation of mud is observed on the object detection sensors, then clean the surface of the sensor. Refer to the Operation and Maintenance Manual, "Object Detection Sensor - Clean/Inspect" section of this manual for addition information on how to clean the sensors.

Note: The object detection sensors have blockage detection diagnostics that display a message to the operator when mud or other substances block the object detection sensors. The event will remain active until the sensor has been cleaned or the blockage is removed.

Installation - Incorrect sensor bracket installation and or alignment may also cause the object detection sensors to give nuisance warnings to the operator. The system may activate the alarm because the object detection sensors are not set to the correct angle.

Note: The brackets may become misaligned over time because of shock and vibration the machine is subjected to during normal operations. The condition of the radar brackets should be inspected daily.

Topographical - The system may detect false objects due to a haul road, loading area, or ready line reflecting the RF energy. One or more false detections are possible when a V-ditch is utilized when parking the machine. The V-ditch can cause a false indication at the front or sides of the machine.

Any critical zone warning that has not been acknowledged will trigger an audible alarm if either of the following conditions are true.

The operator places the machine in gear and attempts to move in the direction of a detected object. For front and rear critical zones only.
The operator places the machine in gear and attempts to move in any direction. For left and right side critical zones only.

Note: Radar information will not be used to determine the exact position of an object. Only the general area of the object relative to the machine will be displayed. The operator must use the camera for the designated machine quadrant in order to determine if an object is in the path of the machine and if action is required.

Power ON/OFF

Power is supplied to the system when the operator turns the machine key switch to the ON position. During the power up process, the display will perform a self test. During the self test, the display will ensure that all of the components are communicating and the alarm on the display will sound momentarily. The system status indicator will turn green, the cameras activate, and the radar view screens activate when the self test is complete. If the self test fails, the system status indicator (refer to illustration5) will turn red. The camera screens will be active and the radar screen will be disabled. If the self test fails, contact your Caterpillar dealer. A screen similar to illustration 3 appears.
