Proximity alarming is based upon the following:
- Machine speed
- Machine position
- Machine heading
- Machine dimensions and avoidance areas defined in office software
The avoidance area (1) is a fixed area around the machine, is configured in the office at the machine class level, and does not change based upon the heading or the speed of the machine. The area does scale as the GPS accuracy decreases. For example, if the GPS accuracy is
Note: The dimensions of the machines and the avoidance areas of the machine are defined in the office software.
The projected path (4) is added onto the avoidance area (1) at the (front or rear) of the machine to determine potential collisions. The total projected path is a mathematical calculation tied to the speed and direction of the machine and is defined in the office software. The projected path will increase as the speed of the machine increases and decrease in the direction of travel as the speed of the machine decreases.
Alarms are based on priority. For example, if a machine is equipped with Object Detection and an object is detected by the Object Detection sensors, that alarm would have higher priority then a GPS-based proximity alarm.
| Priority Alarms | ||||
| Other Machine | ||||
| Path | Avoidance | Body | ||
| Your Machine | Path | Low | Low | High |
| Avoidance | Low | Low | High | |
| Body | High | High | Critical | |
Refer to Table 1 for priority of the alarms.

When the proximity awareness audible alarm is sounded, identify the other machine and the location of the other machine before you move your machine. Failure to identify the location of the other machine prior to moving your machine can result in product damage, personal injury, or death. |
The caution zone proximity alarm is generated when any of the following occur:
- Projected Path on Projected Path
- Project Path on Avoidance Zone
- Projected Path on Body Area
The projected path (5) appears on the plan view and a proximity alarm icon (6) appears in the bottom right corner. During caution, the icon is solid. Depending on configuration, a single audible tone is sounded for 1.5 seconds. Refer to Illustration 2 and Illustration 3 for an example of a caution zone proximity alarm.

(7) Stop zone alert icon | |
A stop zone proximity alarm is generated when any of the following activities occur:
- Avoidance zone on body area
- Body on body area
The projected path (5) appears and a proximity alarm icon (7) appears in the bottom right corner. During stop, the icon flashes. A solid audible tone is sounded. Refer to Illustration 4 and Illustration 5 for an example of a stop zone proximity alarm.

When the proximity awareness audible alarm is sounded, identify the other machine and the location of the other machine before you move your machine. Failure to identify the location of the other machine prior to moving your machine can result in product damage, personal injury, or death. |

Unknown machines are treated as a rotational machine and have a default body area and avoidance area that is defined in the configuration file. These machines are represented as an arrow on the display. Illustration 6 shows an unknown machine type and the default body area and avoidance area. The same rules apply regarding alarming for machines that are unknown.
