3.4 Step #12: “Rotation” sensor calibration
This sensor is available if the range limiting feature is fitted to the system, in this case a
sensor is used to monitor the slew position of the crane.
Encoder type:
This will be factory set and should not be changed in “Enable/ Disable
sensors”. It represents the type and manufacturer of the encoder that is fitted.

Zero:
This is used to set the zero datum point when an absolute encoder is fitted as the
slew sensor. If a relative encoder as 33M0118 is installed and selected, you don’t need
to do the “zero”. To set the zero datum:
Rotate the machine to the zero datum point, normally centred over the front of the
machine, and press
“
”
to set the slew angle reading to zero and permanently store
this point.
Ratio:
This value will only be available if a multi-turn encoder is specified above and
represents the number of turns that the encoder rotates for a single 360° rotation of the
crane. To set this ratio:
1)
Position the crane at an identifiable slew position and check that it will be safe to
rotate the machine for a full circle.
2)
Select
“ratio”
