OM6007 2/99 Optional Equipment - Section 6 Payload Meter II Page 6-3 PAYLOAD METER II ON BOARD WEIGHING SYSTEM (OBWS) GENERAL INFORMATION The payload meter stores in memory various operating data. This data includes: The Payload Meter II On Board Weighing System displays and records the payload weight along with other operating information. The system consists of a payload meter, pressure sensors, deck mounted lights and an inclinometer. 1) The payload, time, distance, and travel speed for each cycle. 2) The date and time that the engine was started and stopped. The payload meter (Figure 6-1) uses the four suspen- sion pressures and an inclinometer to determine the load in the truck.
The payload weight can be displayed in short tons or metric tons. 3) The date and time of each fault that occurred or was canceled. 4) The total payload and the overall number of cycles for a specific time period. There are three external deck-mounted lights on each side of the truck. The lights indicate payload weight divided into three separate stages. A forecast feature will flash a deck mounted light predicting the payload weight if the next bucket of material is dropped into the body. This data is retained even when the power is switched off. The stored data is backed up by an internal battery.
The data can be down loaded from the payload meter to a personal computer when a communication cable is connected to the port inside the cab. FIGURE 6-1. PAYLOAD METER II 1. Display panel 7.
