Edition: February 2007

Î

To complete the installation of the load cell it is necessary after installation to

pre-stress the load cells. This can be performed in two ways - either by
hanging a 10 kg weight onto one load cell or re-installing the weigh bin and
placing a 20 kg weight into the bin. This weight should stay in place for ten
seconds and then removed. Repeat this procedure three times.

Î

Do an empty and full calibration (see manual) and operate as normal.

9.6.5 Replacing

controller

Determining blender model

See 7.7.3 Input TrueBlend Model. After installing new controller, verify that the
blender model designated on the control matches the model number of the
blender it is connected to.
