10.7.6 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 hazard area. Bear in mind that, due to the boom bending for example,
the overall height is increased if you set down the load.
