HANDLING PAYLOAD METER

OUTLINE OF SYSTEM

The payload meter detects the signals from the pressure sensors, clinometer, body float detection, neutral de-
tection, and travel speed detection, and calculates the payload by using the microcomputer built in the control-
ler.
Also, it displays the calculated payload on the machine monitor and indicates the loading state with the external
display lamps.
You can download the data saved in the payload meter to a personal computer by using the special software (if
equipped). The measurement is performed by statistically processing the signals from the pressure sensors,
etc.
The road surface roughness, sudden acceleration, and sharp braking can decrease the accuracy.
For higher accuracy, maintain the road surface and smoothly accelerate and decelerate.
Although the following functions are installed, you do not need to change them for the standard operation. If set-
ting is required, ask your Komatsu distributor.
Setting of Loading End Travel Dist
The payload meter judges that loading is completed when the machine travels continuously 160 m from the
loading pit. If the machine dumps within 160 m, the controller does not judge that dumping is performed, thus
the cycle data is not completed at this time. This is used to change Loading End Travel Dist when the distance
between the loading pit and dumping pit is very short.
Display section of payload
While the machine monitor is displaying the standard screen,
the payload is displayed as shown in the figure.
External display lamp
The external display lamps are on top of the cab.
To make them visible for the digging operator or wheel loader,
there are 2 sets of external display lamps: Each set consists of
3 lamps ((1) green, (2) yellow, (3) red).
The display of the external display lamps changes according to
the payload.
