The zones where the system will warn the operator that a preset limit is being
approached can be changed as required. These values are defined during the
tests performed by the technician during the calibration of the system.
Limits values are not active when the electric power is first applied to the i4500
and they are automatically disabled if electric power is removed.
Reaching an operator’s preset limit (set in the Limits Setting Mode) will not
result in crane lockout.
