5.8 Calibrating the Outrigger Position Sensor
For cranes with digital switch outrigger position sensors, replace the faulty sensor. No calibration is
needed.
At power up, the system will use the last used OPS position and select the corresponding chart. It will
display a white arrow above the corresponding outrigger position on the screen. The operator can then
continue with setup as normal.
The system will pick the chart based on these inputs:
DI1 DI2 Chart
0 1 No-Span
1 0 Mid-Span
1 1 Full-Span
0 0 Error
5.9 After the Calibration Routine
When the calibration routine is complete, thoroughly test the unit to ensure the radius on the unit is
accurate to + .5 of a foot. No negative tolerance is acceptable.
In order to perform load testing, a known weight is necessary. Perform testing from 2-3 different boom
angles, as well as extensions.
The load must 10% when testing, no negative tolerance is acceptable. If the load is outside
these limits, the calibration should be rechecked for accuracy.
