b.
If the crane exceeds 100% of its rated capacity for a given condition, the overload alarm will activate. In this mode,
the following indications are given:
1)
The overload screen (figure 12) will appear, and the alarm beeper will beep rapidly.
2)
After approximately 10 seconds, the overload screen (figure 12) will be replaced by the primary operating

replaced by a flashing OVERLOAD text message and the alarm beeper will beep rapidly.
c.
When the crane's boom angle falls below the minimum value for the load chart (0.0), the minimum boom angle
alarm will activate. In this mode, the following indications are given:
1)
The minimum boom angle alarm screen (figure 13) will appear on the LCD display (figure 2, item 1).
2)
The alarm beeper will beep rapidly.
3)
After approximately 10 seconds, the LCD display (figure 2, item 1) will alternate between the minimum
boom angle alarm screen (figure 13) and the primary operating display screen (figure 10).
d.
When the crane's boom angle exceeds the maximum value for the load chart (80.0), the maximum boom angle
alarm will activate. In this mode, the following indications are given:
1)
The maximum boom angle alarm screen (figure 14) will appear on the LCD display (figure 2, item 1).
