"Brightness setting" pushbutton
The brightness and thus the legibility of the data display and the
buttons can be adjusted at any time with this pushbutton.
(10) "Buzzer off" key
The acoustic alarm can be suppressed by pressing this pushbut-
ton, although not before the alarm has sounded a minimum of 5 s.
The alarm will sound again after approximately 10 s if the cause of
it being triggered is still present.
The acoustic alarm sounds in the following situations:
System test, overload condition, imminence of a hoist limit situation (when the
hoist limit switch function is registered by the LMI system), disruption of the LMI
system, or presence of operating errors recognized by the system.
(11) "TARE" key
The
"TARE"
key is for the purpose of outputting the net load on the
Actual load display.
The net load is the current load minus the load
hoisting equipment and the hook block. The
"TARE"
pushbutton
must be pressed
before
the hoisting process is initiated.
After the button is actuated, the Current Load display is set to zero (tared). After
the load has been raised, the Current Load display will then show the net load
(payload). As soon as the working radius (by angle or radius modification) is modi-
fied, the display shows again the current load and the taring function is completed.
Note:
The current load includes the hook block, the hoist rope and all of the load
lifting tackle. The net load is the current load on the hook without load lifting
tackle. Display errors can be caused by the effects of environmental influences
such as wind on the boom or the load.
