Table 3-2: Alarm Characteristics
Note that the audible alarm can be canceled. It is the Tab
button on the display. Refer to item 1 in Figure 3-20. It can be
canceled once the boom is no longer being moved. When
boom motion again becomes apparent in the control system,
the audible alarm will be restored.
When a limit is reached, the Main Screen shows an indicator
for this condition (again in addition to audible alarms and
potential effects on the crane functions). Figure 3-21 shows
the Main Screen example; the swing limit has been reached.
There are similar symbols for the other limitations; Table 3-3:
shows the boom up/down (boom angle) limitation active
symbol; the radius limitation active symbol; the height
limitation active symbol; and the wall limitation active symbol.
If there are multiple limitations active (such as a swing
limitation and a height limitation), then the appropriate
symbols are cycled on the display with a time interval.
