Payload Meter III - Section 60 OM6009 1/04 Page 60-14 Haul Cycle Warning Flags The payload meter expects haul cycles to progress in a particular way. When something unexpected takes place, the system records a warning flag. Several events within the haul cycle can cause a warning flag to be generated. Each one indicates an unusual occurrence during the haul cycle. They do not nec- essarily indicate a problem with the payload meter or payload calculation. F: Final Zone to Dumping Transition This message is generated when the payload meter senses a Body-Up while it is calculating the final pay- load indicating that the operator has dumped the load.
It may also be generated if the Body-Up signal is not properly reaching the payload meter and the weight in the truck falls dramatically while the truck is calculating the final payload. H: False Body Up A: Continuous Loading This message indicates that the body was raised dur- ing the haul cycle without the load being dumped. The Body-Up signal indicated that the truck was dumping, but the weight of the truck did not fall below 20% of the rated load. This message is generated when the truck is loaded over 50% full without the payload meter sensing swingloads. This indicates that a continuous loading operation was used to load the truck.
It may also indicate that the payload meter did not receive the Brake Lock input while the truck was being loaded. There may be a problem with the wiring or the Brake Lock was not used. The payload meter will not mea- sure swingloads unless the Brake Lock is used dur- ing the loading process. I: Body Up Signal Failed This message indicates that the load was dumped without a Body-Up signal being received by the pay- load meter. The weight of the truck fell below 20%, but the payload meter did not receive a Body-Up sig- nal from the sensor. B: Loading to Dumping Transition This message is generated when the payload meter senses a body up input during the loading process.
This message is usually accompanied by a no_final_load flag. J: Speed Sensor Failed This message indicates that the payload meter sensed the truck loading and dumping without receiving a speed signal. C: No Final Load K: New Tare Not Calculated This message is generated when the payload meter is unable to determine the final payload in the truck. Typically, this means that the payload meter switched from a loaded state to the dumping state before the load could be accurately measured. The payload meter was not able to accurately calcu- late a new empty sprung weight for the truck to use as the tare value for the haul cycle.
The tare value from the last haul cycle was used to calculate pay- load. D: Maneuvering to Dumping Transition This message is generated when the payload meter senses a Body-Up input during the maneuvering or repositioning process indicating that the operator has dumped the load. It may also be generated if the Body-Up signal is not properly reaching the payload meter and the weight in the truck falls dramatically while the truck is maneuvering or repositioning. The payload meter did not have proper data to start the haul cycle with after powering up. When the PLMIII powers off, it records the data from the haul cycle in progress into memory.
This flag indicates that this data was not recorded the last time the pay- load meter was shut down. This can happen when the main battery disconnect is used to shut the truck down instead of the keyswitch. A haul cycle with this warning flag should not be considered accurate. Haul cycles with this warning are displayed in red on the Payload Summary window and are not included in the summary statistics for reports or display. L: Incomplete Haul Cycle E: Average Load or Tare Used This message indicates that the recorded payload may not be as accurate as a typical final load calcula- tion.
Typically, this is recorded when loading begins before an accurate tare is calculated or the load is dumped before the load can be accurately mea- sured.
