RCL Early Warning
Refer to Figure 3-69
If about 90% of the maximum permissible load is exceeded,
an RCL early warning is given:
• An intermittent buzzer tone sounds.
After five seconds, you can switch off the buzzer
tone using the CE button (1).
• The lamp (2) lights up.
• The display (3) shows the current percent of maximum
load, e.g. 91%; the bar is yellow.
NOTE: If the current crane movements continue to be
carried out in the same direction, there is an RCL
shutdown.
RCL Shutdown
There are different types of RCL shutdowns:
• Shutdown due to overload,
• Shutdown due to an error message, refer to the Error
Submenu, page 3-101.
When operating with a hydraulic luffing jib, an overload
condition can develop when changing the angle of the jib.
When this occurs the lowering of the hydraulic luffing jib is
stopped by the RCL.
Shutdown Due to Overload
Refer to Figure 3-70
If about 100% of the maximum permissible load is exceeded,
shutdown occurs due to overload:
• All crane movements which increase the load moment
are switched off.
• The hydraulic luffing jib will not be allowed to lower—
increase the angle.
• A continuous buzzer tone sounds.
After five seconds, you can switch off the buzzer
tone using the CE button (4).
• Lamps (5) and (6) light up.
• The display (3) shows the current percent of maximum
load, e.g. 100%; the bar is red.
• The value on display (2) is equal to or greater than the
value on display (1).
