Truck Payload Measurement System (TPMS)
The Truck Payload Measurement System (TPMS) is a subsystem of VIMSTM 3G. The TPMS performs the following functions for information of the payload cycle:
Calculate
Record
DisplayIn addition to the payload weight, the TPMS records the following data for each payload cycle:
Start time of the cycle
Start date of the cycle
Loading time
Empty time
Loaded time
Loaded travel time
Empty travel distance
Loaded travel distance The onboard memory can record information for approximately 2400 payload cycles. If the register for the payload cycle becomes full, the new data for the payload cycle is written over the data of the oldest cycles. The onboard payload data can be downloaded for further analysis. After a successful download, the onboard payload data can be reset. Payload weight data can also be broadcast via a user supplied radio telemetry system. If the radio telemetry system has been enabled, the calculated payload weight will be broadcast under the following conditions:
A loader pass has been detected
The truck speed has exceeded 5 mph and the Reweigh feature is enabled
A truck has Traveled with a payload for a distance that is greater than .16 km (0.1 M)
Information about the complete cycle is also available to broadcast at the end of the payload cycleThe "load cycle" is displayed on the Advisor display. The calculated payload weight is displayed automatically during loading. Payload status lamps provide feedback to the loader operator during the loading operation. The payload status lamps will indicate green until the truck is fully loaded. The payload status lamps will indicate red when the truck is fully loaded. During the loading process, the Advisor will display the information that is listed in Table 1.

Message Description
"Loading" Continue to load the truck.
"Fully Loaded" The truck is fully loaded.
"Last Pass" An additional pass is required to load the truck fully. Various parameters of payload can be accessed via the Advisor menus at any time during the load cycle.Note: The last pass indicator works correctly in loading applications that require at least three passes of the loader. When a loader pass is used to spot the truck, a minimum of four loader passes are necessary for the last pass indicator to work.Whenever the physical configuration of the truck has been changed a manual calibration must be performed. The calibration procedure is performed when the truck is empty. The replacement of the suspension cylinders is an example of a condition that would require a manual calibration."Automatic recalibration" of a truck occurs when an empty truck has stopped. This calibration will compensate for conditions that can affect the empty weight of the truck. Carryback weight and fuel weight are two variable conditions that will affect the weight of an empty truck. Some parameters can be modified with the service tool to support a wide range of machine configurations. Information such as "total number of loads hauled" and "total weight hauled" can be displayed on the Advisor display. These totals can be reset by the operator via the Advisor display. For example, you can use this
