Overriding the RCL in an emergency
If the RCL has shut down all crane movements,
you can cancel the shutdown with the key-
operated switch (1).
Once the shutdown is cancelled, the crane
operation is no longer monitored and the
switched off crane movements are enabled
again.
The power unit speeds are reduced to 15%.
Requirement
– The engine for crane operation is running.
Cancelling a shutdown
• Turn the key-operated switch (1) to the left or right once.
– Now all crane movements will be enabled for 30 minutes. The crane
movements will no longer be monitored by the RCL .
– The RCL will show an information code;
à p. 11 - 48.
The status display will flash red.
At a degree of utilisation over 110% the warning signal will sound;
à p. 11 - 42.

Risk of accident due to overridden or faulty RCL
It is not permitted to work with an overridden or faulty RCL.
Set down the load immediately and stop operating the crane if the RCL is
faulty.
You may only override the RCL if it becomes absolutely necessary in the
event of an emergency. This is to put the truck crane into a safe state in the
event of a malfunction. In this case, do not perform any movements that
would increase the load moment.
