Optional Equipment - Section 6 OM6007 2/99 Page 6-30 Payload Meter II Normal Operation of the Scoreboard On power up, the Scoreboard will display "888" and then display the current software version, "10". The sign will then go blank until the Payload Meter begins sending load information. There is also a small light that blinks once per second in the center of the top portion of the last digit that is visible by close inspec- tion. This light indicates that the sign is powered and operating normally. During the typical loading cycle there is a short delay from when a bucket load of material is dumped into the body and when the Scoreboard indicates the weight.
This delay is caused by the Payload Meter waiting for the oscillations in the suspensions to settle out before calculating a current load. The Scoreboard will display the current load calculated by the Payload Meter after each swingload. If the truck operator releases the brake lock and begins to drive before the last swingload calculation is made, the Scoreboard will never display the last swingload. The Scoreboard will display the last load calculation made during the loading process until the final load calculation is made approximately 160 meters from the shovel. At this point the final load will be displayed. This number will remain until the truck dumps the load.
There will typically be a difference between the last swingload and final load calculations. PAYLOAD METER BACK PANEL
