11.7.7 Shutdown by working range limiter
If a limit value is reached, RCL shutdown will occur. All movements that would go
closer to the limit value will be disabled. Shutdown will remain active even if you
switch off the monitoring function.
The RCL display also shows an information symbol. You must leave the shutdown
area in order to enable the movement.
If you override the RCL, the shutdown will be overridden and all movements
enabled.

Risk of accidents due to overriding shutdown procedures!
Override RCL only if it is absolutely necessary and you have a clear view of the
danger area. Bear in mind that, due to the boom bending for example, the overall
height is increased if you set down the load.
