4 Work range limit function
If the work range limit area is registered in the AML and if the crane enters the limited area, the
AML performs an auto-stop.
The AML has the following work range limit items.
Height
Boom upper angle limit
Boom lower angle limit
Work radius
Left-hand swing
Right-hand swing
Note: When the AML override switch is on, work range limit function is
canceled.
When slow stop function is canceled, swing work limit is canceled.
When swing free is selected, swing sometimes does not stop.
4.1 Item selection, registration and cancellation
With the AML in normal display state, if <Work range> is pressed, the AML goes to the work
range limit registration and cancellation state.
Whenever
<Work range > or <Forward> is pressed, the AML changes the selected limiting
items cyclically in the following sequence of operations. Pressing <Back > moves the selected
item backward.
Height => Boom upper angle limit => Boom lower angle limit => Work radius => Left-hand swing
=> Right-hand swing => Height=>....
During item selection, the AML flashes to display the selected limit symbol while the other limit
symbols (not selected) are turned on. If the key <
Set > is pressed, the AML registers (if already
registered, it cancels) the current position as the selected limit function value and terminates the
work range limit registration and cancellation mode. Pressing
<Set> inverts the item registration
states .
If the key <Initial display> is pressed, the AML exits the work range limit registration and
cancellation state .
