safe working load. An overload status may therefore be imminent!

Overload warning
This red symbol is lit to indicate that the maximum crane load has been reached or has already
been exceeded. At the same time the yellow warning symbol is lit.
The acoustic alarm sounds an uninterrupted tone.
Warning, SLI bypass
This red symbol lights up during the manual override of the power-off function of the safe load
indicator.
No acoustic alarm. This status is recorded in the data logger.
Warning, stroke end (A2B)
This red symbol lights up to indicate that a stroke end status has occurred.
A stroke end status is recorded if the load block comes into contact with the boom head. There is a
danger in this case that the lifting rope will break and the load will drop. A stroke end state can be
caused by the load being pulled against the boom head or the boom being extended or lowered
without playing out the lifting rope.
The red STOP symbol also lights up at the same time. The acoustic alarm sounds an uninterrupted
tone.
Warning, stroke end bypass
The symbol is lit during the override of the power-off function of the hoist limit switch system.
No acoustic alarm. This status is recorded in the data logger.
