Medium L and M Series Wheel Loaders Cat Production Measurement Application on Machines Equipped with Product Link: PLE631 or PLE641 Caterpillar

Weigh Range Setup

The weigh range is the range of the linkage that measures the payload while raising the linkage. For accuracy:

• The machine must not be digging

• The linkage must not be accelerating in the weigh range

Weigh range

For best accuracy, allow 20% lift height between the start of lift and the start of weigh range.

• 20% will eliminate the effects of acceleration during lift

• Lift acceleration looks like additional weight to the payload system

This range must be adjusted from the default if:

• End of dig or start of lift is higher than 30% (Then raise Start of Weigh Range)

• Final height is below 65% (Then lower Start of Weigh Range)

Software configuration parameters in Implement Configuration screen of Cat^® Electronic Technician (Cat ET) are:

• "Payload Weigh Activate Lift Position" = Start of weigh range - (50% default)

• "Payload Weigh Range Configuration" = Size of weigh range - (15% default)

To view linkage position in % and set the weigh range in the Information, touch:

1. Display: "Settings" > "Payload" > "Set Weigh Range"

Illustration 2	g06130031

Weigh range icon (1) will appear when the linkage is within the configured weight range.

Improper Settings

The possible negative effects of improperly setting the "weigh range" must be understood. The weigh range should be set to an area that allows the smoothest operation to occur. The following table lists the possible problems that may occur from incorrectly adjusting the weigh range.
