System Information
Small Off-Highway Truck System
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.

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 object detection sensors and video to provide the operator with additional information about the work area around the machine. The display interfaces with the object detection sensors that are mounted front and rear of the machine. The object detection sensors reduce blind spots and increases perimeter awareness. The system will detect objects as small as an adult human 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 standing adult human. However, due to the limited number mounting areas for the object detection sensors on the machine, there are gaps in the object detection sensor coverage that would allow the system to miss these smaller objects.
Illustration 2 below shows the coverage that is provided by the object detection sensor.

Maximum Range for pickup trucks or 55 gallon metal drum 10 m (32 ft). Maximum Range for human targets 8 m (26 ft). (A) 8 m (26 ft) (B) 1.54 m (5.05 ft) | |
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. 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. |
 |
| NOTICE |

Object Detection Sensor 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 the following condition is 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.
Effects on System Operation
The operation of the system can be affected by any of the following factors.
|
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 such as rain, snow, and sleet can create road conditions that may cause mud to build up on the face of the object detection sensor. The moisture in the mud can reduce the effectiveness of the coverage of the object detection sensors. The mud absorbs the RF energy that is 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 do not have blockage detection diagnostics. Hence the operator or maintenance personnel should ensure that the sensor surface is cleaned and no blockages are present on the surface of the sensor prior to beginning of the operation.
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 sense false objects 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 object detection sensor brackets should be inspected daily.
Topographical - The system may sense objects even though no objects are present. These detections may occur if the grade of a haul road, a loading area, or a ready line are significant enough to reflect RF energy in the same way as a vehicle or berm would. One or more false targets 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.
If an object is in the critical zone, the display will provide an audible and visual warning.
Any critical zone warning that has not been acknowledged will trigger an audible alarm if the following condition is 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.

Power ON/OFF
Power is supplied to the system when the operator turns the machine key switch to the ON position. A screen similar to Illustration 3 appears.
 | |
| Illustration 3 | g03432926 |
Note: The operator has to be read and understands the disclaimer, then the Accept button may be pressed
The above screen appears for 10 seconds and after 10 seconds the screen automatically switches to the screen shown in Illustration 4.

The operator can press the "Accept" soft button on the screen or wait for 10 seconds for the disclaimer screen in Illustration 5 to disappear

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. When the self-test is completed, the following occurs:
- The system status indicator will turn green.
- The cameras will be active.
- The proximity bar will be active.
Note: Ensure that the model of machine listed on the lower left corner of the start-up screen matches the machine that is being operated. If the correct machine does not appear, contact your .Cat dealer Refer to Illustration 5.
the operator is responsible for observing the self test to ensure that the alarm sounds and the camera views are visible.
If the self test fails, the system status indicator will turn red, the camera screens will be active, and the object detection sensor screen will be disabled. If the self test fails, contact your Cat dealer.
