Message center
The TPMS 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.Module (Speedometer/Tachometer Display)

Speedometer/Tachometer display
The speedometer/tachometer display module indicates when the transmission has shifted to second gear to activate the second gear reweigh function.Module (Keypad)
Illustration 4 g00728423
Keypad
The keypad is the operator interface with the VIMS. The operator can perform the following functions of the TPMS with the keypad:
Change the display units. (The payload information can be displayed in English or Metric units.)
Modify the target payload weight of the truck. (The service tool must be connected.)
Turn on the last pass indication.
Turn off the last pass indication.
Enter an operator identification number. (A pit identifier for each load can be entered in the place of the operator identification number.)
Calibrate the system. (The service tool must be connected.)
Clear resettable totals.Pressure Sensor (Suspension Cylinder)
Illustration 5 g00728426
Suspension cylinder pressure sensor
The four pressure sensors (Suspension cylinder) convert the payload into a signal that is proportional to weight. This signal is then passed to the VIMS ECM.Lamps (Payload Status)
Illustration 6 g00728429
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 TPMS allows the truck 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 loader operator 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 the loader operator that the target payload weight has been reached or exceededDisplay (External Payload)

External payload display
The external payload display is a 356 mm × 686 mm (14 inch × 27 inch) screen. The external payload display is mounted on the side of the truck. The external payload display displays the measured weight of the material that is in the truck body. The payload information is displayed in 254 mm (10 inch) red digital numbers. There are three configurations of the external payload display that are available. These configurations are listed below:
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.VIMS RS-232 (Telemetry Broadcast Port) Communication
When the VIMS RS-232 Broadcast port is connected to a telemetry system, VIMS will automatically broadcast "Events and Payload" information. The VIMS telemetry port is also referred to as "Service Port 2". The following items describe both
