VIMS Main Module - The VIMS main module is the brain of the Truck Payload System. All computing and storage of the cycle data takes place in the VIMS main module.
Message Center Module - The Truck Payload System uses the message center to display the calculated weight of the payload. Text messages on the message center tell the truck operator when the target payload weight has been reached.
Keypad Module - The keypad is the operator interface with VIMS. The operator can perform the following VIMS Truck Payload System functions with the keypad:
- Change the display units. The payload information can be displayed in English units or Metric units.
- Modify the target payload weight of the truck.
- Turn ON the last pass indication.
- Turn OFF the last pass indication.
- Enter an operator identification number or a pit identifier of the load.
- Calibrate the system.
- Clear resettable totals.
VIMS Interface Modules - The VIMS interface modules receive input signals and processes input signals from the four suspension cylinder pressure sensors. The interface module converts the payload signals into a digital equivalent value. The interface module then passes the information to the VIMS main module. The VIMS main module uses the information in the Truck Payload System.
Suspension Cylinder Pressure Sensors - The four suspension cylinder pressure sensors converts the payload into a signal that is proportional to weight. This signal is then passed to the interface modules.
Payload Status Lamps - The payload status lamps are located on both sides of the truck. The payload status lamps show the loader operator when the target payload weight has been reached. The VIMS Truck Payload System allows the operator to configure the payload status lamps to indicate the last pass. The payload status lamps will illuminate the following colors.
- A green lamp signals the "loading tool" to continue loading the truck.
- A flashing red lamp tells the "loader operator" that one additional pass is required to load the truck to capacity.
- A steady red lamp signals that the target payload weight has been reached.

External Payload Display - The external payload display is a
- Dual Displays (right hand and left hand displays)
- Right Display (right hand display)
- Left Display (left hand display)
The external payload display receives data through the VIMS broadcast (system telemetry) port. There are two modes of operation. The modes of operation are listed below:
Single Mode - This mode is for machines that are not equipped with a radio telemetry system.
Passive Mode - This mode is for machines that are equipped with a radio telemetry system. This mode allows the display to access data for the payload weight without interfering with the operation of the radio telemetry system.
Transmission Control Module - The transmission control module converts the following conditions into a digital equivalent value: body position, ground speed, transmission gear and parking brake. The transmission control module then passes the information to the VIMS main module over the CAT data link for use by the VIMS payload system.
Engine Control Module - The engine control module calculates fuel flow. The control converts this data into a digital equivalent value. The engine control module then passes the information to the VIMS main module over the CAT data link for use by the VIMS payload system.
