BALANCER AS 3746758 - Caterpillar

Illustration 1 g00490540The pressure within the suspension cylinders is not stable for a few seconds after the loader pass. The suspension cylinders are still recoiling from the sudden application of a large mass. After the pressure in the suspension cylinders has stabilized, the first pass weight is calculated. The pass weight is then displayed on the message center. The message is shown below. The external payload status lamps continue to signal the loader operator with a green light.
Illustration 2 g00490541Note: NNN.N represent the present payload weight.With each additional loader pass, more material is loaded onto the truck. This action causes the suspension cylinder pressures to increase sharply. Each sharp increase in suspension cylinder pressure adds another loader pass. The pressure within the suspension cylinders must stabilize before the calculation of the payload weight is completed. The new payload weight is displayed on the message center. This message is shown below.
Illustration 3 g00490541Note: NNN.N represent the present payload weight.If the last pass indicator is enabled, the VIMS Truck Payload Measurement System (TPMS) calculates a running total of the weight for all passes. The red payload status lamps flash to warn that another pass will result in a payload of at least 95% of the target payload. This amount is the present payload weight plus the weight of the most recent pass. The following message is shown on the message center:
Illustration 4 g00490542Note: NNN.N represents the present payload weight. After the final loader pass (the last pass) has been completed, the red payload status lamps are turned ON solid. This action indicates that the present payload weight is greater than 95% of the target payload weight. The following message is shown on the message center:
Illustration 5 g00490544Note: NNN.N indicates that is greater than 95% of the target payload weight that was programmed into VIMS with the service program code PAYCONF.When the truck begins to travel away from the loading site after being loaded, the following message is shown on the message center:
Illustration 6 g00490546Note: NNN.N represents the last calculated payload weight. The TPMS measures the weight of the load again once the truck has exited the load site. The measurement is made when the truck has shifted into second gear. The payload information automatically disappears from the message center after the load has been measured. The message center then returns to the background mode, indicating that the "loading state" is complete. The truck is now "traveling loaded". Automatic Calibration Adjustment
Whenever the truck is "stopped empty" the VIMS TPMS will automatically adjust the calibration. The calibration is adjusted for weight variations such as fuel load and carryback weight that may affect accuracy. The carryback weight includes any material that is stuck to the body and under the body. The adjustment amount is limited to a small range around the original calibration value that was established with the service program code PAYCAL. Collapsed Suspension Cylinder Detection
Whenever the truck is "traveling empty" at a speed less than 12 km/h (7 mph) the system will continuously monitor the suspension cylinder
