11.5.6 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 also shows an error message. To enable the movements, you must
leave the shutdown range and acknowledge the error message;

ple, the overall height is increased if you set down the load.
