“<MIN CAL” after attempt is
made to Calibrate. The LSS Module expected the empty platform to weight more for calibration.
1. The platform is resting on the ground or another obstruction during calibration. The
platform’s weight must be transferred through the Shear Beam Load Cells and into
the support structure for an accurate calibration.
2. The wrong Model Selection was made under the LSS Module’s MACHINE SETUP,
MODEL. This should be set to “MODEL=BOOM LIFT”. Improper selection may lead
the LSS Module to expect different empty platform weights.
3. One or more shear beams are improperly mounted (there is interference between
the platform and support structure) or upside down. Refer to the Installation portion
of this manual to resolve the issue.
4. The calibration difficulty may be a result of a Measurement Performance issue.
Review the Possible Resolutions under that category.
