CRANE FUNCTIONS
Operation of the Rated Capacity Limiter
(RCL)
If the current rigging mode of the crane is registered properly,
the RCL prevents the permissible lifting capacity from being
exceeded and the crane from being overloaded.
The current rigging mode is based on measured values and
manually entered values:
During the operation of the crane, a visual and acoustic early
warning is issued before the load limit is reached and the
functions are shut down that would lead into the overload
range.
Switching on the RCL
NOTE: The RCL is not switched off if you turn the ignition
key to position R instead of position 0 to restart the
engine. The test program will not run and you will
not have to acknowledge the settings again.
The RCL is switched on together with the ignition.
A test program runs after switching on the ignition. A
continuous buzzer tone sounds for about 2 seconds and a
lamp test is performed:
• Check whether you can hear a buzzer tone.
• Check that the lamps indicated in Figure 3-120 light up
briefly after turning on the ignition.
If the specified time is insufficient, switch on the ignition
again or conduct a lamp test, refer to Lamp Test, page 3-58.
Contact Crane Care if one or more lamps do not light up.
After the test program the two lamps (1) light up and all
power units are disabled.
What is displayed depends on whether the RCL had been
switched off for up to 48 hours or had been switched off for
more than 48 hours, refer to the following sections.
DANGER
Tipping Hazard!
If the actual rigging mode varies from the displayed
rigging mode, the maximum load displayed by the RCL
will not correspond to the permissible lifting capacity
allowed in the Load Chart. Inaccurate programming of the
RCL allows the crane to be improperly operated.
You may only override the RCL if it becomes absolutely
necessary in the event of an emergency. This is to put the
crane into a safe condition in the event of a malfunction. In
this case, do not perform any movements that would
increase the load moment.
Serious injury or death may occur if the crane is
overloaded or overturns.

WARNING
If the lamps or the buzzer fail, notify Crane Care and have
the error rectified.
In the meantime, pay particular attention to the lamps in
the event of a failure of the buzzer and vice versa.
