On-screen messages provide the operator with visual warnings of conditions that occur during
operation of the system.
Extension Sensor
The extension sensor provides an increasing voltage proportional to the extension of the boom. A
cable attached to the boom head provides a low current electrical path for the ATB signal.
Function Kick-Out
Electrically operated solenoids disconnect the control lever functions for boom hoist lower, telescope
out, and winch up whenever an overload or an ATB condition occurs.
Pressure Transducers
Two pressure transducers measure the pressure in the boom hoist cylinder. The resultant Total
Moment signal is processed to provide a continuous display of the load suspended below the point of
lift.
Operator Alarms
These alarms, when properly set by the operator, define the operating range. This is achieved by
means of minimum and maximum angle, maximum height, and/or maximum length. These alarms
can be programmed for each job site and allow the operator to work in a defined area.
