Operator Programmable Alarms
Work Area Alarms (If Equipped with Swing Sensor)
This alarm permits the operator to define an operating zone by only two set points. The use of this
method results in a more defined operating zone. The following diagram illustrates the operating zone
and the exclusion zone.
The set points are calculated using the tip of the boom. This means the set point isn’t determined just
by the swing of the boom, but also the distance from the centerline of rotation to the tip of the boom.
The work area alarm, defines an imaginary vertical plane between two set points. When the plane is
passed the red warning indicator will be displayed, the alarm will sound, and the message “!!
EXCLUSION ZONE !!” will flash as shown below.
