In such case, consult your Komatsu distributor.
Display of prediction
Loading state and prediction are indicated by the lamps in different colors and their lighting status (lighting up or
flashing).
When the load changes in steps for each bucket loaded, the payload meter automatically estimates the predict-
ed total payload if one more bucket is loaded, and indicates the predicted payload by flashing of the appropriate
lamp. Flashing of the red lamp (3) indicates that it will be overloading with the next loading.
The predicted load display and actual payload display are shown at the same time.
Predicted number of bucket loads: 4
Payload display and predicted payload when loading of 9.0 t per one bucket is loaded onto HD325.
1st time
• The payload is 9.0 t, and the predicted total payload at the next loading is 18.0 t.
• All lamps are not lit.
2nd time
•
The payload is 18.0 t, and the predicted total payload at the next loading is 27.0 t.
• Green lamp (1) flashes, and it indicates that the predicted total payload of the 3rd loading is 18.3 t or more.
3rd time
• The payload is 27.0 t, and the predicted total payload at the next loading is 36.0 t.
• Green lamp (1) lights up, and it indicates that the total payload is 18.3 t or more.
Yellow lamp (2) flashes, and it gives a warning that the predicted total payload of the 4th loading is 32.9 t or
more.
4th time
• The payload is 36.0 t, and the predicted total payload at the next loading is 45.0 t.
• Green lamp (1) and yellow lamp (2) light up, and they give a warning that the total payload is 32.9 t or more.
Red lamp (3) flashes, and it warns that the predicted total payload of the 5th loading is 38.3 t or more.
Perform the loading carefully so that the red lamp (3) does not light up.
DETAILS OF DATA STORED IN MEMORY OF PAYLOAD METER
The payload meter records the data of the dumping cycle (from each dumping to the next dumping).
Cycle data items

• The payload which is a saved data corresponds to the weight carried in each cycle.
• The maximum limit for saving cycle data is 2900 cycles. If the data in memory exceed 2900 cycles, the
newest data are written over the oldest data.
• Download the recorded data through RS232C port to a personal computer installed with special software (if
equipped).
The downloaded data are saved in the text form (CSV type) in a certain place on the personal computer.
For details, see the operation and maintenance manual for the special software.
You can take in and check the downloaded data with the text file read function of the commercially available
spreadsheet software.
