Functions of the VIMS Onboard system and the VIMS Off-Board SystemThe Loader Payload System that is used on large wheel loaders is a subsystem of the Vital Information Management System. The system is more than a device used to measure payload weight. The features of the system allow accumulated data to be downloaded. The data can then be used to help manage the loader and the truck fleet. This manual has been developed as a resource tool for use at all levels: (machine operator, service technician and management personnel). The manual has been divided into five sections in order to make the information easy to locate. These sections have been grouped into two areas:OnboardFunctions that are used during the setup and the operation of the Loader Payload System at the machine level. These functions are set by using the onboard components that are listed here: VIMS keypad module, the Message Center and the payload STORE button.The following onboard functions are covered in this manual:Basic Operation - This section gives a general overview of the payload system. This section also provides the information that is listed here: basic information that is needed for the setup of the payload system and a guide for the operation of the payload system for a new user.Operating The System - This section provides a comprehensive overview of the operation of the Loader Payload System. Calibration - This section provides detailed step-by-step instructions on performing the calibration of the Loader Payload System. OFF-BOARDThese functions require the use of a computer and software programs. The software programs are designed to perform the functions that are listed below to the onboard VIMS information and the machine configurations.
Communicate with the machine.
Analyze the onboard data.
Modify the machine information.The following off-board functions are covered in this manual:VIMSpc Service Tool Software - This section provides instruction on downloading the payload information from the onboard system and generating and interpreting the payload reports.

Block Diagram of the VIMS Loader Payload System Hardware Version 4.0The Loader Payload System calculates the weight of the payload in the bucket. The weight of the payload is based on the relationship between the position of the boom and the corresponding pressure in the lift cylinders. The pressure in the lift cylinders is sampled over a specific range. This range is known as the WEIGH RANGE. The system stores the weight of each bucket in onboard memory. During loading, the current bucket and truck weights are displayed on the VIMS Message Center. Data about the bucket load is stored automatically. When the truck is loaded, the operator must press the STORE button in order to store the truck's payload information in the onboard memory. When the STORE button is pressed, the optional horn is sounded. The horn signals the truck to proceed.
