Normal Operation Of The Scoreboard; Payload Meter Back Panel - Komatsu 930E-2 Shop Manual

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.
